Description:
Macro lens in standard focal length for the Pentax 6x7 system. The lens itself provides half life size magnification (1:2), and life size magnification (1:1) with the smc LIFE-SIZE CONVERTER which screws into the front of the lens. The trumpet-shaped lens hood attaches to the front of the converter as well as to the front of the lens in lieu of the converter.

Magnification is increased to 1x with the dedicated LIFE-SIZE CONVERTER 67, which screws into the front of the lens. The trumpet shaped lens hood also fits the converter.

Usage:
The 100/4 Macro is a bit of an odd lens. Its front element is recessed in a funnel and has a 49mm filter thread at the bottom. This is where the lens hood or 49mm filters screw into. If you are using the LSC you remove the hood and screw the LSC into the 49mm filter thread, then you screw the hood into the top of the LSC. You can also mount 77mm filters onto the top of the lens hood. The lens has two distance scales, one when using the LSC and one when you are not. Confused, refer to one of the later Pentax 67 “Interchangeable Lenses Operating Manuals” for more information.

OUTDOORS: The 100/4 macro is not the easiest lens to use outdoors, especially with the LSC attached. The subject to film distance is so small (inches/centimeters) that you will block a lot of light falling on your subject. Also to get the proper DOF you will be using slow shutter speeds, so hand held shooting is out and MLU is required. This also makes it very difficult shooting moving subjects, such as insects and wind blown flowers. Using a tripod will fix some issues, but maneuvering one into position that is strong enough to support a 6x7 body & 100/4 is also going to be very hard.

INDOORS: For me this is where the 100/4 macro shines. In a controlled environment using daylight colour temperature lighting, I can get close enough to the subject using a tripod, MLU, slower film (100ISO) and very slow shutter speeds. If you own a Pentax 67II, one of the “bright” telephoto/macro screens will help in focusing.

FILTER: As previously mentioned you can use either 49mm or 77mm screw in filters. You can’t use Pentax 6x7 77mm bayonet filters on this lens.






Summary:
I can produce brilliant shoots indoors with this lens and it’s extremely sharp. Getting 1x magnification without extensions tubes is also great, as the TTL/AE metering will work while the lens DOF lever is in left the “AUTO” position. The only real issue with the 100/4 macro is the short film to subject distance, this is mostly due to the shorter focal length of the lens and the higher magnification achieved. Ideally the FL would have been 200mm, but never the less this is a truly excellent lens.

The images this lens produces are EXACTLY why I bought into medium format in the first place. Can't imagine a sharper, contrastier lens. It's so stunning to view the chromes on the light table! Ordinary macro work won't stand up to 30x40 enlargements. No one can believe the 30x40's are from a 6x7 Macro lens and not a large format system. Even corner sharpness holds up quite well.
My initial fears about the standard multi-element life-size converter were unfounded. The lens reaches half life-size without the converter and comparing those shots with full life-size shots indicates almost no difference. I still can't believe how well the converter works. Add a 77mm Canon 500D multi-element close-up lens to the front of the "trumpet" and you get appx. 1.5x life-size with marketable sharpness and color rendition. This set-up has rendered my extension tube set moot. 1.5x in medium format is almost unheard of...
This lens also serves as a ridiculously sharp normal lens. It's bigger and heavier than the 105 (which is also sharp), but this "new generation" Macro model gets my vote based on imaging beyond belief. By "new generation" I'm referring to the fact that this lens was developed and released around the same time as the 67II--both very recently in Pentax 67 terms.
I pretty much put my 35mm system on the shelf for 3 years after shooting through this lens

The Pentax 67 system is almost four decades old and has been my camera of choice since its introduction. Many of the 67 lens designs are also that old. Then, they were state-of-the-art; today, not so much.

The 135mm ƒ/4 macro lens focused down to 1/3X magnification with no extension tubes while providing images of good quality at normal distances. But, it's a bit low in contrast, lacking the snap typical of other Pentax 67 lenses, and 1/3X is hardly close focusing by today's standards.

Enter the next generation: the 100mm ƒ/4 macro lens. It focuses to better than 1/2X with no extension tubes and greater than life-size with a front-of-the-lens converter. The compact lens hood screws into the front element of the lens or converter, and the lens cap snaps on the front of the hood, so the whole assembly makes a nice package when not in use.

The front converter means I don't need to dismount the lens to get greater than 1/2X magnification. The converter goes on and off much faster than extension tubes, takes only one hand, and I'm less likely to disturb my macro set-up. Of course, I can still add an extension tube or tubes to get more than 2X magnification.

The 100mm macro lens is a fine performer at all distances. That its close-up performance is beyond reproach will not surprise anyone, but it's a really great lens all the way out to infinity.

Weight  600g (21.2 oz)  






Pentax 67, 100mm F4 Macro lens is part of my system for last five years. It performs great on it's own and with life size converter it is perfect. Contrast, sharpnes and colour are outstanding. I use it with 2X converter and/or with extension tubes hend held. Magnification goes to 2.7X with Life Size Converter and Extension tubes. With bellows and copy stand that lens can do magnification of 5X and more. With bellows exposure factors are about 40-50. So, one needs good studio lights with such set up

Surprisingly small for a 200mm macro. Not a lot larger than a 100mm.
Nothing to complain about the image quality. Excellent sharpness and good controlled aberrations even fully open. Bokeh and colours are very good, too. Wish it would have 9 aperture blades.

Now the negative aspects:
Handling on the K-1 is very bad because you can´t switch the tripod mount to vertical orientation... it collides with the huge protuding prism. The screw on the right side of the mount is very near the cameragrip and don´t leave much space for the fingers. Even my small fingers...
Very frustrating to work with that issues.

A larger focus throw would be nice for better focusing at close distance. It´s already easy, but could be better.

A little bit overpriced...

I´ve only used that lens for macro work. So I have no experience how it performs on longer distances.
Output is outstanding, but the usage is sometimes not a joy.

It performs outstanding with the Rear Converter A 1.4x-L, too. Even fully open absolutely pleasing image quality. This is my tool to eliminate the mentioned negative things with the tripod mount

This lens is an amazing piece of engineering. It is an excellent macro (1:1) as others have raved about. It provides fantastic working distance for those tricky subjects such as spiders, particularly jumping spiders. Colours are superb, natural but with a nice vibrant lift. Sharpness is there from wide open with DOF not too punishing like 50mm lenses can be. Best of all, this lens can be stopped down a loooong way without diffraction damaging IQ.

I have also used this lens for distant portraits. Surprisingly, the lens gives a wonderful 3D effect owing to the narrower FoV and simply stunning OoF Bokeh. The 200mm allows for subject isolation in crowded spaces giving the impression of intimacy when it is not really there. I used this feature to great effect by snapping candid portraits without the subject knowing.

IQ loss is almost negligible when used with a quality teleconverter turning the lens into a 300mm. I would like to try the Pentax AF teleconverter to see what is offers.

Focusing on subjects at medium to long distances is very easy through tiny finger tip twists of the focusing helicoid, while macro subjects are dealt with through effortless yet pronounced focusing adjustments giving a sense of control - although movements are never overly involved (some adjustments on other lenses can take an uncomfortably long time to adjust when close focusing). The tripod mount is perfectly designed as a focusing aid when hand held shooting. The mount sits nicely in the palm of my hand while I toggle the focusing helicoid with gentle fingertip control.

There is some fringing evident and when it emerges can take some effort to remove in PPing. Not overly distracting but noticeable. Perhaps the only negative. I have market it down in that regard.

The lens costs a lot of money and is a very serious investment. Not having the benefit of testing the lens prior to purchase was a significant barrier to making a $2000 investment - BUT - I took the leap of faith and glad I did. This lens will be with me till the end, then, hopefully, enjoyed by my children. It is heir loom quality - no doubt about that

และสิ่งที่ต่างคือ cine lens ใช้เป็น T stop ไม่ใช้ F stop  แล้วมันต่างกันอย่างไร เวลามีการซูม รูรับแสงจะเปลี่ยนเอง

t.stop ค่าทุกอย่างเหมือน f.stop แต่วัดจากปริมาณแสง ไม่ใช่ขนาดทางผ่าน t.stop คือ f.stop ที่ชดเชยแสงที่เสียไปจากเนื้อแก้ว (t.stop เดียวกัน จะ lens ตัวไหนก็สว่างเท่ากัน และที่ค่าเดียวกัน t.stop จะสว่างกว่า f.stop)

Description:       
The Helios 44 (-x) is the standard, fast, 58mm lens typically found as the kit prime on the Zenit-series russian SLRs. The earliest versions were just "-44", later they acquired the additional -2, -3, -4 etc up to -7, the latter is supposed to be the highest resolution version and normally commands highest prices, however sample variation is likely to be more significant with soviet lenses! This page reviews the 44-2 - probably the most common version. It is a classic preset lens with two rings, one to set the desired f-stop, one to open/close the iris, f2-f16. More recent versions include multicoated lens elements. There are also non-preset "M" versions, and "K" versions with PK mount. See relevant review pages.
Helios 44's were made in more than one factory. KMZ was probably the most prolific producer, the one in pic 1 however has the Valdai logo.

I do love the Helios 44-2

While wide open the lens is still quite sharp in the centre of the frame, as you move outwards it becomes quite blurry, although much of this has to do with the shallow DOF and getting the manual focus spot on at first can be a little difficult. Once you master the MF this lens becomes one of my favourite pieces to shoot with.

Would highly recommend, especially with the price tag!!

I love the bokeh and flare in this lens!
The great thing with old lenses is that they have personality
which new digitally optimized items lack.
You must fight the flare into something creative and
the lower contrast wide open gives the images an analog feel to it.

When used properly (hood is a must), this lens has incredible sharpness. Corner sharpness wide open stinks, though. Absolutely unbelievable performance for a $15 lens, given that some pay up to 100 times more for a portrait lens. "It's all that one may ever, ever need", as a forum colleague said. The focal length is noticeably different from a standard 50mm.
I will let some of my pictures tell the story of the lens. The one which is not wide open, is at f/11.

The Mir-1 37mm f2.8 is essentially the standard USSR moderate wide angle lens. The optical formula is believed to be as shown and is a copy/derived from the Zeiss Flektogon. It is available primarily in M42 mount, also M39 mount (early versions particularly), t-mount (Mir-1A) and Russian bayonets like the Kiev-10/Kiev-15.
There are several variants see pics:
Mir-1 silver M39 (early versions);
Mir-1 black M42 (most common)
Mir-1A with t-mount (according to allphotolenses only manufactured for a year and seems uncommon);
Mir-1B M42 (VOMZ).
Mir-1V

Also at least three different manufacturies made them: KMZ, VOMZ, ZOMZ, ZA. Lenses with the logo of the ZOMZ: Industrial Amalgamation Zagorsk Optical-Mechanical Factory (as on the silver version pictured) are the most common. Note too the first two digits of the serial number indicates the year of manufacture. However the optical formula and technical construction of the variants appears to be consistent:

One word to describe this soviet wonder: SUPERB!

Sharpness is pretty good if stopped down a bit. Almost no signs of CA. This lens has a rather unique flare capability. Bokeh is quite surprisingly good, with the (in)famous Petzval effect. It is very sturdy, despite it's lightweight.

The photo below was taken using this lens,at f2.8 with a 12mm macro extension tube. Keep in mind that it was post-processed.

I just bought one of these on eBay and I am not familiar with the design. I notice that there is an aperture ring from 3.5 to 90 and another ring from 30 to 200 in green numbers. The two rings move in parallel. There is no obvious focusing ring. My questions are, what are the green numbers, why do they move in parallel, and how do you focus? Thanks.

Hello.. that's one of the classic 180° auxiliary fisheye lenses. It went by a number of different distributor names... Kenko, Soligor, Samigon, Spiratone, etc. Rumor has it that the front optic of one was used as the eye of Hal in Stanley Kubrick's 2001: A Space Odyssey.

It should have come with an adapter ring to screw on to the front of a prime lens. Sizes 49mm and 55mm seem to be the most common but you can probably add a low profile step up/down filter ring to the mix if needed to fit 52mm. The fisheye was designed to project a full 180° image circle on a full frame (digital FX, 35mm film) camera. The top and bottom of the circle will get cropped when used on a APS-C format camera.

The ring with the green numbers should be set to the focal length of the lens it is mounted on... in reality, the fisheye was designed to work best with a 50mm focal length and anything else just reduces the view. Set the f-stop of the prime lens wide open and use aperture control of the auxiliary lens instead. For best results you should never stop down more than what the prime lens is set to.

Focus is done using the prime lens, but you can probably just leave it on infinity.

Thank you, very helpful. The eBay seller did not mention its being an auxiliary lens, but it makes sense. I had just ordered a 49 to 49 adapter ring for something else, so I'm all set. I suspected it would crop on an APS-C. I do remember that scene from 2001.

Actually, the adapter is not needed at all for a 49mm filter size lens. I attached the Soligor to a 50mm prime lens and took my first shots. Very cool, except that the image is definitely not sharp around the edges! I was thinking that a smaller aperture would help. But I am not sure where the manual aperture control for the Soligor may be located.
Also, is there a way to use a polarizer on the lens? Maybe sandwiched between the prime and the Soligor? Thanks.

You might be able to sandwich a polarizing filter between the two lenses but the image circle will likely appear smaller.
