The Pentax Q series was a series of mirrorless interchangeable-lens cameras made by Pentax and introduced in 2011 with the initial model Pentax Q.[1] As of September 2012, it was the world’s smallest, lightest interchangeable lens digital camera.[2] The first models used a 1/2.3" (6.17 x 4.55 mm) back-illuminated sensor CMOS image sensor. The Q7, introduced in June 2013, uses a larger 1/1.7" type sensor (7.44 x 5.58 mm).[3]

2018-4-22 20:06

Characteristics[edit]
The Q series small sensor size means that it has a crop factor of 5.6× (or 4.7× for the Q7 and Q-S1) and a short flange focal distance (FFD) of 9.2mm. With the 5.6× crop factor, an adapted 100mm lens has the equivalent field of view (FOV) of a 560mm telephoto in the 35mm full-frame format. An additional implication of the 5.6× crop factor is that depth of field (DOF) is increased proportionally for any given aperture setting. This gives the Pentax Q an advantage over larger formats in some situations that can offset the other limitations that arise from its smaller sensor size.
The short FFD of the Pentax Q series enables lenses from many manufacturers to be adapted to it, including: Olympus OM, Canon FD, Minolta, M42 screw mount, M39 Leica, C-Mount, D-Mount, Pentax K, and Pentax 6×7.[4] A Pentax adapter with a synchronized shutter for Pentax K-mount lenses was released in October 2012.[5]
The camera is equipped with 'SR' sensor-shift image stabilization technology to improve image quality when using the camera without a tripod. It works with all native and adapted lenses. The Pentax Q also features a "blur" mode to provide a pseudo shallow focus effect when desired.

adapter ตัวแรก  C mount-pentax Q   แล้วเจ้า c mount นั้นเป็นเม้าท์ของเลนส์อะไร  

A C mount is a type of lens mount commonly found on 16 mm movie cameras, closed-circuit television cameras, machine vision cameras and microscope phototubes.
C-mount lenses provide a male thread, which mates with a female thread on the camera. The thread is nominally 1.000 inch (25.4 mm) in diameter, with 32 threads per inch, designated as "1-32 UN 2A" in the ANSI B1.1 standard for unified screw threads. The flange focal distance is 17.526 millimetres (0.6900 in) for a C mount.
Merely to say that a lens is "C-mount" says very little about the lens' intended use. C-mount lenses have been made for many different formats. C-mount lenses are built for the 8 mm and 16 mm film formats and the 1/3", 1/2", 2/3", 1", and 4/3" video formats, which corresponds to a range of image circles approximately from 5 to 22 mm in diameter.
Depending on the format, the design of the lens and its performance will differ considerably. For example, for the 4/3 format, a 12 mm lens is a wide-angle lens and will have a retrofocus design. For the 2/3-inch format, a 12 mm lens is "normal" and can have a simple and fast double Gauss layout. For the 1/3-inch format, a 12 mm lens is long and can have a telephoto design.
Some TV lenses lack provision to focus or vary the aperture, so may not operate properly with film cameras. Also, some TV lenses may have bits that protrude behind the mount far enough to interfere with the shutter or reflex finder mechanisms of a film camera.
Although C-mount lenses have a back focal distance far too short to be used with 35 mm film SLRs or any existing digital SLR, they can be mounted on interchangeable-lens mirrorless digital cameras. One such system is the Micro Four Thirds, being used by Olympus and Panasonic. However, the vast majority of C-mount lenses produce an image circle too small to effectively cover the entire (micro-)four-thirds sensor, which has approximately 22 mm diagonal. This produces what is popularly called vignetting but is better described as a mismatch between camera format and lens format.[1] The Nikon 1 series and the Pentax Q series can use C-mount lenses without vignetting.
C mount was created by Bell & Howell for their Filmo 70 cine cameras.[2] The earliest Filmos had a slightly different mounts, known as A mount, and B mount. C mount was found on Filmo 70 cameras with serial numbers 54090 and higher,[3] probably from about 1926. Soon after, other camera manufacturers adopted the same mount, and it became a de facto standard for 16 mm cine cameras.

adapter ตัวที่ 3 คือ  M 42- pentax Q  แล้วเม้าทื M42 นี่มันของเลนส์อะไร

The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount, which shares the 42mm throat diameter, but differs by having a 0.75mm thread pitch.) It was first used in Zeiss' Contax S of 1949; this East German branch of Zeiss also sold cameras under the Pentacon name; after merger with other East German photographic manufacturers, the name Praktica was used. M42 thread mount cameras first became well known under the Praktica brand, and thus the M42 mount is known as the Praktica thread mount.[1] Since there were no proprietary elements to the M42 mount, many other manufacturers used it; this has led to it being called the Universal thread mount or Universal screw mount by many. The M42 mount was popularized in the United States by Pentax; thus, it is also known as the Pentax thread mount, despite the fact that Pentax did not originate it.

adapter ตัวที่ 4 คือ Leica M39- pentax Q  แล้ว M39 ของเลนส์อะไร

The M39 lens mount is a screw thread mounting system for attaching lenses to 35 mm cameras, primarily rangefinder (RF) Leicas. It is also the most common mount for Photographic enlarger lenses.
True Leica Thread-Mount (LTM) is 39 mm in diameter and has a thread of 26 turns-per-inch or threads-per-inch (tpi) (approximately 0.977 mm pitch) of Whitworth thread form. Whitworth threads were then the norm in microscope manufacture. The Royal Microscopical Society (RMS) thread, also known as society thread, is a special 0.8" diameter x 36 tpi Whitworth thread used for microscope objective lenses and Leitz was a major manufacturer of microscopes, so the tooling at the plant was already set up to produce the Whitworth thread form. The Soviets in the 1930s produced their early FED cameras in M39×1 (39 mm by 1 mm DIN thread).[citation needed] Early Canon cameras also used a different M39 × 24 tpi thread mount,[1] called "J-mount".
True LTM lenses have a flange focal distance of 28.8 mm, though this is of little importance for lenses used on bellows enlargers.
The Soviets later adopted the LTM mount for their Zenit single-lens-reflex (SLR) cameras, though with the longer optical registration of 45.2 mm, required to allow the mirror room to flip out of the focal path when a picture was taken.
The mount was developed by Oskar Barnack at Leica to provide a system that would allow for the exchange of lenses on their new small film cameras (Leica Type 1 and Leica Type 2), as Zeiss Ikon had indicated that their forthcoming Contax rangefinder cameras would have interchangeable lenses. The LTM system was tested at the request of Leitz on lenses manufactured in small batches by Hugo Meyer in Germany and marketed with a run of Leitz cameras by A. O. Roth in London. The test marketing program was a success, so regular production with Leitz camera bodies and lenses was introduced on the Leica II, and featured on the Leica Standard and Leica III.
Until the 1970s the 39 mm mount was the norm for exchangeable lenses in rangefinder cameras. The high cost of quality lenses led to the dual use camera/enlarger of the lenses, hence the fact that enlargers also accept 39 mm lenses.

adapter ตัวที่ 5 คือ  Nikon AI mount-pentax Q

AI lens

Manual Nikkor lenses, produced from 1977 until mid 80s, introduced Automatic Maximum Aperture Indexing, designed to let the camera body know what is the maximum aperture of the mounted lens for metering. Non-AI lenses coupled to the camera's meter through a system that required a pin on the camera to be mated to a slotted prong on the lens before the lens was mounted, then the aperture ring on the lens had to be turned from one extreme to the other to index the meter to the maximum aperture of the lens. AI eliminates this entire procedure because meter coupling and indexing occur automatically when the lens is mounted on the camera. Most AI lenses made until a few years ago were also supplied with the coupling prong so they would be compatible with either metering system. With all-black barrel, rubber focusing ring and multicoated elements.

adapter ตัวที่ 6  Contax/Yashica    Y/C mount-pentax Q

Yashica and Contax manual-focus lenses with a common bayonet mount were introduced in 1975 simultaneously on the Contax RTS and on the Yashica FX-1. The Yashica range of lenses included a premium range of lenses for the more serious photographer (termed 'ML' or 'MC' for multi-coating), while consumer SLR cameras were usually equipped with 'DSB' lenses, which had single-coated optics. The top of the line was the renowned Zeiss AE series of lenses, intended for the Contax SLR cameras, each of which displayed a T* for Zeiss' proprietary multi-coating. Some Carl Zeiss lenses were made in Germany and the rest in Japan under Zeiss license. But all of these lenses were interchangeable with any Yashica or Contax camera equipped with the C/Y bayonet lens mount.

2018-4-22 20:48

In 1983, Kyocera acquired Yashica, and continued to manufacture Yashica ML lenses, as well as the Carl Zeiss AE T* lenses under license. The C/Y mount was slightly modified in 1985 with the new Zeiss 'MM' design lenses, which permitted the use of program and shutter-priority on the Contax 159MM and subsequent bodies. The new MM lenses are distinguished visually by the color of the f-stop markers: the highest f-stop on the MM lenses is marked in green. (On the older lenses, also called AE lenses, it is marked in white.) The newer MM lenses are still backwards-compatible with all Contax and Yashica cameras, but with older AE lenses one cannot use all available programmed and shutter-priority exposure functions on the post-1984 Contax bodies. Unfortunately, the program mode of later manual-focus Yashica (Kyocera) bodies (FX-103, 107/108/109MP) does not have full MM compatibility.

2018-4-22 20:48

One of the more interesting adaptations of the Zeiss AE/MM lenses is to the Contax AX camera, built by Kyocera. This camera allows autofocus of the manual-focus Zeiss lenses, by actually moving the film plane (rather than the lens) back and forth. The AX can also be used with other lens mounts, via adapters.
Later Contax SLR lenses for the auto-focus Contax N series built by Kyocera use a completely different and dedicated AF lens mount, aptly called "N mount."
While every brand has its adherents, optical testing has generally shown that Zeiss AE/MM lenses were among the sharpest ever made for a production 35mm SLR. Adapters to use Zeiss T* AE/MM lenses on other cameras, most notably Canon EOS digital SLRs, have proved popular.

2018-4-22 20:49

While not to Zeiss standards, Yashica ML and MC multi-coated lenses for the C/Y bayonet mount have also earned a reputation for high quality. Yashica already had a reputation for fine optics dating from the early 1960s with its optics supplier (later subsidiary), Tomioka Optical, and is also believed to have benefited from its licensing and manufacturing relationship with Carl Zeiss.

adapter ตัวที่ 7 Canon FD mount-pentax Q

The Canon FD lens mount is a physical standard for connecting a photographic lens to a 35mm single-lens reflex camera body. The standard was developed by Canon of Japan and was introduced in March 1971 with the Canon F-1 camera. It served as the Canon SLR interchangeable lens mounting system until the 1987 introduction of the Canon EOS series cameras, which use the newer EF lens mount. The FD mount lingered through the release of the 1990 Canon T60, the last camera introduced in the FD system, and the end of the Canon New F-1 product cycle in 1992.
The FD mount was based upon and replaced Canon's earlier FL mount (which in turn had replaced the R mount); FD-mount cameras can use FL lenses in stop-down metering mode. Though never officially explained by Canon, others have attempted to assign a meaning to the "FD" designation. One such attempt states that the "FD" notation stands for "Focal-plane shutter with Dual linkage for diaphragm control"; in actuality, there were two linkages and two signals: the automatic aperture lever, aperture signal lever, full aperture signal pin, and automatic exposure lock pin. This is twice the previous lens series, which used the "FL" designation, said to mean "Focal-plane shutter, Linked mount."[citation needed]
Over the 21-plus years of production, Canon introduced 134 different FD lenses ranging from 7.5mm through 1,200mm in seventeen different fixed focal lengths and nineteen different zoom ranges, one of the most, if not the most, extensive manual focus lens lines ever produced.[citation needed]
The Canon FD system enjoyed huge popularity in the 1970s and 1980s, when it established and grew a market share with professional photographers as well as having equipped over a million consumer users. Indeed, sales of the Canon AE-1 camera alone exceeded one million.[1]
Canon obsoleted the FD mount by its decision to create the all-electronic EF mount. Thus, the FD mount system, with no provision for auto-focus, is now commercially obsolete, and Canon FD cameras and lenses are available for low prices on the second-hand market. This makes the system very attractive to 35mm film photographers who demand the highest optical quality,[2][3] while not needing auto focus capability.
FD lenses are now enjoying a renaissance since they can be used on a mirrorless interchangeable-lens camera with a suitable adapter. High-quality lenses at relatively low prices are very attractive for that application and the lack of autofocus is not a big objection due to new technologies which aid manual focus accuracy.

adapter ตัวที่8  Olympus  OM mount-pentax Q

The Olympus OM System (O = Olympus, M = Maitani) was a line of 35mm single-lens reflex cameras, lenses and accessories sold by Olympus between 1972 and 2002 (some accessories were sold until early 2003).
The system was introduced by Olympus in 1972, more than a decade after Nikon, Canon, and other manufacturers had established their own SLR ranges. The range was designed by Yoshihisa Maitani, chief designer for Olympus, and his staff. The nucleus of the system was a series of compact bodies divided into an advanced series and a later consumer-oriented series. The first model was the all-mechanical M-1 which, after pressure from Leica (which already had an M1 model), was renamed OM-1. At the same time the M system was renamed OM System. The camera included a full-aperture TTL Cadmium-sulphide (CdS) exposure meter, and a bayonet lens mount of relatively large diameter. By the end of the 1970s it was joined by the semi-automatic OM-2 and consumer-oriented OM-10. Olympus continued the naming pattern with the 'professional' OM-3 and OM-4, and the consumer-level OM-20, OM-30 and OM-40. The cameras were accompanied by a series of Zuiko-branded lenses, as well as a generous selection of accessories. The majority of OM bodies and lenses were manual-focus only; the OM-707 of 1986 was the only true autofocus model.

Olympus produced a wide variety of OM camera models over the years. These were divided into two distinct series. Cameras with single-digit model numbers were the 'professional' series, optimized for more advanced features and durability. Two-digit (or more) model numbers, or letters, meant a 'consumer' camera designed for ease of use.
All the consumer-grade models were discontinued after 1992, since the market for manual-focus SLR cameras had declined greatly. The consumer line returned in 1997 with the Cosina-sourced OM-2000 model. Professional and advanced-amateur demand for the high-end models continued, and they were produced until 2002, along with the consumer-grade OM-2000.[1]

adapter ตัวที่ 9 Pentax  PK mount-pentax Q

The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975,[1] and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras.

2018-4-22 21:07

2018-4-22 21:07

2018-4-22 21:07

The Pentax K-mount has undergone a number of evolutions over the years as new functionality has been added. In general, the term K-mount may refer to the original K-mount, or to all its variations.
Originally designed by Zeiss for an alliance with Pentax[citation needed], it was intended to be a common lens mount for a proposed series of cameras and lenses. However, the plan failed to work out and the two firms parted company amicably, but Pentax retained the lens mount and at least one Zeiss lens design for its own use.[citation needed]
K-mount[edit]
The original K-mount is a simple bayonet connection with three tabs. It was introduced with the K series of cameras. The lens is locked into the camera with an approx. 70° clockwise turn (when looking at the front of the camera).
The only linkage with the camera is mechanical and involves the aperture. A slot between two of the bayonet tabs on the lens allows the stop-down coupler from the camera to sense the aperture setting on the lens and adjust the light meter display accordingly. Opposite this is the diaphragm release from the lens which extends into the camera body and holds open the spring-loaded diaphragm of the lens. When setting up a shot this keeps the diaphragm fully open. When the shutter is released, so is this lever. It allows the diaphragm to close to the desired setting while the film is being exposed, and opens it again after the shutter closes.
Both of these linkages are arranged so that they are aligned and spring-loaded by the act of inserting the lens and turning it until it locks.
Bodies equipped with the original K-mount include the K series, the M series except the ME F, and the LX. Lenses that support it include those labelled 'SMC Pentax', 'SMC Pentax-M' and 'SMC Pentax-A'. These K-mount bodies cannot use lenses that lack an aperture ring, such as FAJ or DA.
K-mount lenses can be used on all Pentax bodies, but are restricted to stopped down mode when used with "crippled" KAF-mount bodies (see below

KA-mount[edit]


Pentax A 50 mm lens displaying the KA-mount
The KA-mount is derived from the original K-mount. It allows the lens's aperture to be set by the body, and thus permits shutter priority and program auto exposure modes. It was introduced in 1983, and is supported by A-series and P-series bodies; Pentax lenses that support it are marked 'SMC Pentax-A'. It is completely backward-compatible with the original K-mount.
The aperture on the lens is set from the body by the same stop-down lever found on the original K-mount, but on KA-lenses this lever is proportional to the area of the aperture opening, rather than the diameter as on previous lenses. This allows the body to easily set a specific aperture, since the relationship to F stops is linear. The lenses add an 'A' setting on the aperture dial, which gives the body control of the aperture. Other, numeric settings are used for manual aperture modes—aperture priority and full manual mode.
Six electrical contacts are added to the bayonet ring. One is slightly recessed and allows the lens to indicate whether the aperture ring is set at 'A' or not. If it is, a pin on the lens extends slightly and makes contact, while if the lens is at any other setting the pin is retracted and does not make contact. The other five contacts are used to encode the lens's aperture range. Each contact on the lens is either conducting or non-conducting, providing a binary 1 or 0, respectively. Two contacts encode the lens's minimum aperture—f/16, f/22, f/32 or f/45; although no Pentax K-mount lens has ever had an f/16 minimum aperture, OEM lenses often have. The other three contacts encode the lens's maximum aperture; their meaning is dependent on the minimum aperture indicated by the lens.

adapter ตัวที่ 10  Canon EF mount-pentax Q

Introduced in 1987, the EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a bayonet-style mount, and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers.
In 2003, Canon introduced the EF-S lens mount, a derivative of the EF mount that is strictly for digital EOS cameras with APS-C sensors released after 2003. EF lenses can be mounted on EF-S bodies but EF-S lenses cannot be mounted on EF bodies. In October 2012, Canon introduced the EF-M lens mount, a derivative designed exclusively for mirrorless interchangeable-lens cameras (MILCs) with APS-C sensors. EF and EF-S lenses can be mounted on EF-M bodies via the optional Mount Adapter EF-EOS M.[1]
Canon claims to have produced its 100-millionth EF-series interchangeable lens on 22 April 2014.[2]

adapter ตัวที่ 11 คือ  Minolta MD mount-pentax Q

The Minolta SR-mount was the bayonet mounting system used in all 35mm SLR cameras made by Minolta with interchangeable manual focusing lenses. Several iterations of the mounting were produced over the decades, and as a result, the mount itself was sometimes referred to by the name of the corresponding lens generation (f.e. "MC", "MD" or "X-600") instead.
All lenses for these mounts are interchangeable between older and newer Minolta manual focus 35mm film SLR bodies. There are exceptions, such as, the lenses before 1961 feature a slightly different aperture leverage, and thus the automatic diaphragm may not work correctly on post-1961 cameras, and later MC/MD tabs may hit a screw of the front cover on earlier cameras.

MD - In 1977, the XD series introduced an additional tab on the lens which reported the smallest available aperture (f/16, f/22, or f/32) to the camera to accomplish shutter priority automatic exposure in S mode on the Minolta XD-7 (XD-11 in the U.S.A.), and later in the P (programmed automatic exposure) mode on the X-700. The proper use of this feature meant that the lenses had to be set to their smallest aperture. In 1981, MD lenses included a minimum aperture lock that prevented the aperture ring from accidentally being moved.

adapter ตัวที่ 12 คือ Tamron -pentax Q

The company started making cameara lenses in 1957 and with their first lens, a 135mm f/4.5 (model #280), they introduced the T mount. According to the company, the "T" stands for Taisei.[4]. It is often erroneously speculated that the "T" stands for Tamron, but Taisei did not change their name to Tamron until many years after the mount was introduced. The T mount is a 42mmx0.75 thread screw mount. According to Tamron, the mount adapter was later modified by another company into the modern T-2 mount adapter but the mount itself remained the same. The T-2 mount adapter consisted of two concentric rings. The inner ring of a T-2 mount can be loosened and rotated so that the lens markings are correctly oriented with respect to the top of camera. The T mount was adopted by many other companies and is still in use today.
Tamron is often erroneously credited with the T-4 and TX interchangeable mounts used by companies like Vivitar and Soligor but Tamron history researchers deny any connection to them, even implying that there may have been patent infringement lawsuits brought by Tamron.[5]. In fact, the evidence points to Tokina as the inventor of the T-4 and TX mounting systems.
The T mount does not provide automatic diaphragm control, and was superseded in 1966 by the Taisei Adapt-A-Matic system, allowing the transmission of the automatic diaphragm for various SLR cameras. Taisei filed two patents on the 1966 Adapt-A-Matic system that are important in the history of interchangeable lens mounts.[6][7]
The Adapt-A-Matic system was subsequently replaced by the Tamron Adaptall system in 1976.[8] In 1979, the company introduced the Tamron Adaptall-2 system, an evolution of the Adaptall, and released the first SP (Super Performance) lenses.

adapter ตัวที่13 คือ Sony Alpha-pentax Q

Sony α (the lower case to Greek letter alpha, often transliterated as Sony Alpha), is a camera system introduced on 5 June 2006.[1] It uses and expands upon Konica Minolta camera technologies, including the Minolta AF SLR lens mount, whose assets were acquired by Sony after the end of Konica Minolta's photography operations in early 2006. Sony also has an 11.08% ownership stake in Japanese lens manufacturer Tamron,[2] which is known to have partnered with Konica Minolta and Sony in the design and manufacture of many zoom lenses.
Prior to the acquisition by Sony, the α branding had already been used on the Japanese market by Minolta for their AF camera system (marketed as "Dynax" in Europe, and "Maxxum" in North America). Sony adopted the name "A-mount system" for the Minolta AF lens mount, which has been retained in their new SLR range.[3]
Sony's entry into the DSLR market dates back to July 2005 where a joint venture with Konica Minolta would have resulted in both companies marketing an updated line of DSLRs to the masses.[4] Between 2006 and 2008 Sony was the fastest growing company on the DSLR market, reaching 13% market share in 2008 to become the third largest DSLR company in the world.[5]
In May 2010, Sony introduced two α NEX mirrorless interchangeable lens cameras equipped with the new proprietary Sony E-mount.[6] A-mount lenses can be used in E-mount cameras with an adapter - four different adapters are available from Sony alone.[7]
Sony announced plans to introduce a special camera service programme for professional photographers since the launch of the α900 in 2008. Sony Imaging PRO Support (a.k.a. SPS) was finally established starting between 2013 and 2015 depending on country.

adapter ตัวที่ 14 คือ  Leica R, LR -pentax Q

The Leica R bayonet lens mount is the standard method of connecting a lens to the Leica R series of 35 mm single-lens reflex cameras. The mount is descended from those used for the Leicaflex, Leicaflex SL and Leicaflex SL2 SLR cameras, but differs in the cams used to communicate lens aperture information to the camera. 3 cam lenses are compatible with all of the Leica SLR cameras, while R-only lenses have a slightly different mount shape that will not fit on the earlier cameras.
The flange focal distance between mount and film is 47 mm.
On 5 March 2009, Leica announced plans to cease production of its R-Series manual focus SLR and lenses.
