adapter ตัวที่ 30 คือ Minalta AF mount-pentax Q

The α mount (or Minolta AF mount or A-mount) was introduced with Minolta's first popular fully automatic autofocus single lens reflex camera Minolta 7000. It is a bayonet lens mount with three main components: The bayonet, the set of electrical contacts, and a rear engagement to couple the camera's lens focusing motor drive with the lens's focusing mechanics. The introduction of the Minolta 7000 in 1985 was a historical step to fully automatic SLR systems for the mass market.
There were some main product generations. The first were the original AF camera body series and the i-series bodies. These were followed by the xi-series bodies which could use the xi-lenses with internal zoom motor drive. The suceeding camera models tolerated the xi-lenses but didn't support their zoom motor. The last generation of analog SLR bodies supported lenses with own internal focusing motor drive (SAM micro motor lenses or SSM ultrasonic silent motor lenses).
The G-lenses became Minolta's series of superior camera optics. The series was continued by Sony when the Japanese electronics giant took over Konica Minolta's SLR development and production assets. Zeiss supported Sony by creating further top-quality α lenses, the ZA-lens edition. In its first 4 years the Sony α system was just a continuation of Konica Minolta's DSLR concept. For the following 4 years 2010 - 2014 it was modified by replacing the DSLR concept by Sony's own SLT concept. But probably the system's second bayonet, the E-bayonet introduced in 2010 for the Sony NEX series of handsome mirrorless digital system cameras and for professional Sony camcorders, will replace the original α mount completely except on the available A-mount/E-mount adapters.

adapter ตัวที่ 31 คือ Pentina Carl Zeiss mount-pentax Q

The Pentina was the Pentacon attempt to produce a leaf shutter SLR, similar to the West German leaf shutter SLRs. I haven't tried Pentina lenses, but Contaflex and Retina lenses have driven me off bothering to adapt leaf shutter SLR lenses - the lenses mostly are optically constrained by the shutter location and diameter, so that they perform worse than the same lens in a focal plane shutter SLR mount, and they are harder to adapt.

adapter ตัวที่ 32 คือ Altix zeiss mount-pentax Q

Altix was a series of sophisticated 35mm viewfinder cameras, made by Eho-Altissa and its successors in Dresden, Germany, from 1938 onwards.[1] Later models have interchangeable lenses.The Altix-NB is the last model built by Altissa in 1958-59 before the merger of several small factories to the huge Kombinat VEB Pentacon.

adapter ตัวที่ 33 คือ Microscope mount-pentax Q

A microscope c-mount adapter is used to connect a microscope camera to the microscope trinocular port. A c-mount adapter has a standard 1" (or 25mm) diameter male thread. This thread matches with the female thread on the camera. C-mount adapters are microscope specific in that the lenses are made to match up with your specific microscope. For example, you would not want to use an Olympus C-Mount adapter on a Meiji microscope. This would most likely result in an image that is not parfocalled, or is not in focus at the same time that your eyepieces are in focus. C-Mount adapters have lenses in them in order to match up with the similar magnification you are seeing through the eyepieces. If you were to use a c-mount adapter with no lenses built into it you would see more magnification than what the eyepieces are currently seeing. This is due to the inherent magnification with image sensors and microscopes. Although this setup can work, most people generally prefer an image that looks similar to their field of view through the microscope.

To compensate for too much magnification at the camera, or to most closely match the field of view in the microscope, you will need a c-mount adapter with a reduction lens built into it. The chart on the right lists the suggested adapter to use when using 10x eyepieces in your microscope, based on the chip size in the camera.
Camera Chip
Suggested
C-Mount
1/4"
0.265x or 0.3x
When using 20x eyepiece you will generally move up one step in magnification. If you had a 1/2" chip with 10x eyepiece the corresponding c-mount would be 0.45x or 0.5x. With 20x eyepieces you would want to use the 0.7x c-mount adapter.
1/3"
0.3x
1/2"
0.45x, 0.5x or .6x
If you were to use a camera with a 1/2" chip in it with a 0.7x c-mount adapter the camera would still work, you would just have a smaller field of view and more magnification at the camera than you would see through the eyepieces

adapter ตัวที่ 34 คือ telescope mount-pentax Q

A telescope mount is a mechanical structure which supports a telescope. Telescope mounts are designed to support the mass of the telescope and allow for accurate pointing of the instrument. Many sorts of mounts have been developed over the years, with the majority of effort being put into systems that can track the motion of the fixed stars as the Earth rotates.

adapter ตัวที่ 35 คือ S mount-C mount-pentax Q

The S-mount is a standard lens mount used in various surveillance CCTV cameras and webcams. It uses a male metric M12 thread with 0.5 mm pitch on the lens and a corresponding female thread on the lens mount; thus an S-mount lens is sometimes called an "M12 lens". Because the lens mounts are usually attached directly to the PCB of the sensor, the standard is often called "board lens". The supported sensor formats range from the smallest 1/6-inch type to the largest 2/3-inch having an 11mm diagonal sensor. The lens mount is usually made of plastic and the lenses lack an iris control. S-mount lenses do not have a flange and therefore there is no fixed lens to sensor distance and they must be adjusted to focus.[1]

คงพอแค่นี้ละครับ  แค่นี้จำนวนเลนส์ที่จะสามารถมาใช้กับ  กล้อง pentax Q ก็มากมายมหาศาล  ขึ้นกับว่าของเดิมเรามีเม้าท์เลนส์อะไรอยู่จำนวนมาก ก็ซื้อเม้าท์นั้นมาใช้ก็จะคุ้มมากที่สุด  

สำหรับตัวผม คงจะซื้อแค่ adapter PK-pentax Q กับ C mount-pentax Q  แค่นี้คิดว่าพอ

แล้วจะเอารูปมาให้ดูกันครับ
