Lens review: The Porst Color Reflex MC Auto 50mm f/1.4 G

This review is about the Porst Color Reflex MC Auto 50mm f/1.4 F lens. I must admit that I hadn't heard of this specific lens before I was doing research on its bigger brother, the Porst Color Reflex MC Auto 55mm f/1.2 F lens. As it happens, an eBay seller had both the 55mm f/1.2 (early f/22 version) and 50mm f/1.4 for sale. The f/22 version of the 55mm/1.2 went for € 139. I was however intrigued by the 50mm/1.4 so I bid on it and was able to purchase it for a mere € 56.




Like its bigger brother this lens was made in Japan for the German Photo Porst chain of camera stores. I have since managed to find that the Porst lenses in K mount were actually produced by Cosina, thereby confirming my hunch. It is no surprise that both lenses have the same kind of style, the later f/16 version of the 55mm/1.2 and this 50mm/1.4 look very much alike. 

The 50mm/1.4 has a nice solid feel to it. You can tell that these were lenses that were made to last. 

Specifications:

Focal length:                        50mm

Minimal focus distance:        0.5 meters

Aperture:                             f/1.4 - f/22

Aperture blades:                  8

Lens elements:                    7

Diameter:                            49mm

Mount:                                Pentax K

Manufacturer:                     Cosina

Built:                                  1970s-1980s

Use

This lens is equipped with the Pentax K mount. As with the 55mm/1.2 its focus ring turns to the left towards infinity. Again this may seem a bit unnatural at first for Pentax users as the Pentax lenses turn to the right.

Focusing is smooth and in general, the lens has a nice feel to it. I've used this lens with Pentax film cameras and with a digital Canon EOS camera via an adapter. Due to the design of the K mount these lenses will not fit APS-H and full frame EOS cameras, the mirror will hit the back of the lens. K mount lenses will only work on EOS cameras with an APS-C sensor (much like the EF-S mount). 

Images

The images you see below were shot with a Canon EOS 90D set at ISO 200. These images were converted from RAW to JPEG, slightly cropped (to just show the chessboard) and resized. No other actions were taken in Photoshop.


f/1.4


f/2.8


f/4


f/8


f/16

As you can see at f/1.4 subject isolation is great! Wide open it also shows chromatic aberration (CA) which disapears when the lens is stopped down. At f/4 it is almost gone and at f/8 there is no sign of it. Wide open there is also some vignetting, although this does not show on these slightly cropped images. As with the f/1.2 version I found it hard to focus with this lens on the EOS 90D which shows, the f/2.8 and f/4 shots are slightly out of focus. When using these lenses solely on AF cameras I do recommend getting a split-image focusing screen for better accuracy.

In the field

I fitted the Porst Color Reflex MC Auto 50mm f/1.4 G to my Pentax LX, loaded it with Fomapan 100, teamed up with fellow photographer Joeri van Veen and headed out for some shots. 

In the field the lens is easy to operate, the fact that it focuses the 'other' way round did not hinder me in any way. And as for the results, judge for yourself:






The harsh winter light posed no problems for this lens. Only when shooting directly into the sun the back light bleached out the subject somewhat as can be seen below.

All in all I found this lens to be a solid performer, both wide open and stopped down. When using it with the Pentax LX I found focusing no issue at all, whilst using it with a digital camera without a split-image focusing screen was sometimes challenging wide open. For the price this lens is a fine performer for as far as I am concerned, this is a keeper.

Camera review: The Kiev 88

The camera

When you see a Kiev 88 the first thing you notice is how much it resembles a Hasselblad V series camera. This is not by accident. When Hasselblad introduced the 1600F model camera, built from 1949 until 1953 they introduced a new camera design. This was not lost on engineers in the Soviet Union and it was decided that the Arsenal factory in Kiev would develop a camera based on the Hasselblad 1600F design. In 1957 they came up with the Салют (Salyut) camera which was basically a reverse-engineered 1600F. At the time the similarity of the two cameras was explained by stating that both Hasselblad and Arsenal based their camera design on that of a camera prototype designed in Germany at the end of World War Two. A nice story but as this mythical prototype has never been found or shown elsewhere that is probably all it is. 

Now the Salyut and the Hasselblad 1600F look very much alike but the Salyut is no exact copy. Both are modular camera's with detachable lenses, film backs and viewfinders. The lenses and film backs however are not interchangeable with the Hasselblad versions. The viewfinder actually is compatible with not just the Hasselblad 1600F but also its V system successors. These are smaller differences too, for instance the fastest shutter speed on the first Salyut models was 1/1500th of a second whilst the Hasselblad had a 1/1600th of a second shutter speed (hence the name).

The original Salyut camera was produced between 1957 and 1972 and during its production run several changes were made. The first series had a self timer and a maximum shutter speed of 1/1500th of a second, the second series lost the self timer and the third series had a reduced maximum speed of 1/1000th of a second. All of these were supplied with the Industar-29 80mm f/2.8 lens. Export versions were built under the names of Zenith 80, Revue 6x6, Revue 80 and Vitoflex. Around 50,000 Salyuts of all versions have been built.

My Kiev 80 as bought

Next in line was the Салют-C (Salyut-S), an improved Salyut produced from 1972 until 1981. Around 30.000 were made. The main difference was the fully automatic diaphragm that the original Salyut lacked. It was standard equipped with a Vega-12B 90mm f/2.8 lens. Like the original Salyut, this camera was exported under different brand names like Soyuz, Zenith 80 (second use of this name) and Kiev 80. Some Kiev 80s were supplied with a different standard lens, the Volna-3 80mm f/2.8. My Kiev 80 however came with the standard Vega-12B lens.

My Kiev 88 as bought

The Salyut-S was succeeded on the production line by the Киев 88 (Kiev 88). These models were produced between 1980 and 1994. The biggest difference between the Kiev 88 and its predecessor was the addition of a hot shoe on the camera body. The Kiev 88 also came with a new TTL metering prism This combination was called the Kiev 88 TTL but as the viewfinder is detachable the only difference between the Kiev 88 and 88 TTL is the use of the metering prism. Its standard lens was the Volna-3 80mm f/2.8. Like its predecessors the Kiev 88 was also exported. In the US it was sold under the Cambron name but usually it was sold as a Kiev 88, the main difference was that this was written in Latin rather that Cyrillic script.

Last in the line was the Kiev 88CM. By now the Soviet Union had collapsed and Arsenal was now a Ukrainian company. The Kiev 88CM (by now Arsenal stopped using the Cyrillic script) was produced from 1994 up until the factory closed in 2009. The biggest difference between the Kiev 88 and the 88CM was the new lens mount. All previously built Salyuts and Kievs had a screw mount not unlike but different from the original Hasselblad mount. With the Kiev 88CM that lens mount was replaced with the Pentacon Six mount. This meant that beautiful lenses such as the Carl Zeiss Jena lenses built for the Pentacon Six could be used on Kievs. As Arsenal already produced their lenses in this mount for the Kiev 60 series of cameras both the original Soviet/Ukrainian lenses in Pentacon Six mount and other lenses who use the Pentacon Six mount can be used.

The closure of the Arsenal factory was not the end of the Kiev line of cameras. There were loads of unsold Kiev 88CMs around and companies like Hartblei and Arax took over that stock. Both companies already offered repairs and upgrades to this line of cameras and started producing their own versions using unsold Kiev 88CMs, upgrading them and selling them on under their own brand names. 

Arax offered the Arax CM and CM-MLU versions, the last one adds a mirror lock up (MLU) to the camera. Hartblei offered the Hartblei 1006 and 1006 Master models with the Pentacon Six mount with the Master version also receiving MLU and Hartblei 1008 and 1008 Master models with the original screw mount. Hartblei also offered a commonality with Hasselblad, theirs are the only Kiev cameras modified to take Hasselblad film backs. The Hartblei modified film backs can also be used on Hasselblad V type bodies, something that cannot be done with the original film backs. 

Unfortunately both companies no longer sell their brands of the Kiev 88 cameras. Hartblei stopped selling and servicing these cameras around 2018. A shame really, I would have loved to get my hands on one of those Hartblei 1006 Master cameras with that Hasselblad commonality. In 2021 Arax also stopped selling new cameras as their supply of Arsenal built bodies ran out. However Arax still offers repairs and modifications to all Salyut/Kiev models at this time (October 2021).

Back to the Kiev 88. My copy was built in 1985 and when I acquired mine (together with a 1976 Kiev 80) it was still in full working order. At that time I had just bought my first Arax version of the Kiev 88CM which I was very happy with. With Arax also servicing, repairing and upgrading all models of this design I decided a few months ago to send mine off to the Ukraine for servicing. I decided to have everything serviced and MLU added. It would also get a black coating replacing the silver look.

Shooting

Shooting with the Kiev 88 (or any of the other camera models described above for that matter) is not for the impatient. Are you in a hurry? Go grab something digital. But if you're willing to spend the time then shooting with this camera is fun. Now when shooting with these Kievs there are a few things you'll always have to remember. By far the most important is to cock your shutter before setting the shutter speed. Doing it the other way around will most likely damage the shutter mechanism. Now, your shutter needs to be cocked before you can compose your shot anyway (cocking it also lowers the mirror) so it is best to just learn and use the mantra 'before doing anything else, cock the shutter'. My Kiev 88 came with both the folding view finder and the TTL metering prism. Working with the folding view finder takes some getting used to. You're looking at a mirror image and when composing moving the wrong way happens almost inevitably the first few times - or more... I opted to fit the TTL viewfinder that I bought together with my Arax after trying the folding view finder. Shooting handheld is no problem with these cameras but I would recommend a tripod when using the folding view finder or when using lower shutter speeds. So, you've set op your shot, cocked the shutter, composed, focused, selected the proper shutter speed and aperture and removed the metal sheet from the film back so you're good to go. One last focus check and CLACK, there the shutter and mirror go. A very satisfying sound.

Images

The Kiev 88 delivers twelve beautiful 6x6 images when using the standard film back. There is also a 645 film back that gets you sixteen 6x4.5 shots. I used the standard film back that came with my Kievs, fitted the Vega-12B 90mm f/2.8 lens and shot some black and white. A few examples, straight from the scanner:

Lens review: The Porst Color Reflex MC Auto 55mm f/1.2 F

This review is about the Porst Color Reflex MC Auto 55mm f/1.2 F lens. This lens was made in Japan for the German Photo Porst chain of camera stores. Two versions of this lens were made, an early version with f/22 as the smallest f-stop and a later version with f/16 as the smallest f-stop. 

This lens review is about the later f/16 lens. The two versions look pretty much the same, but apart from the f/22 f-stop there are a few differences. The f/22 closest focal distance is 0.5 meters, with the f/16 this is 0.6 meter. Cosmetically there are a few differences too, For instance, the f/22 version has the lens serial number on the front, whilst the f/16 variant has the serial number on the aperture ring. The f/16 version also has the Pentax style raised alignment dot, something the f/22 version does not have. The upper barrel of both lenses is slightly different too, although they both share the 55mm filter thread. These lenses look very much like contemporary Cosina lenses so they could have been made by Cosina. I however haven't found any confirmation of this.

I bought this lens about 5 years ago as sort of a backup for my Pentax 50mm f/1.2 lens. The price of the Porst that time was € 156, pretty cheap for an f/1.2 lens. I paid quite a bit more, € 429, for my Pentax version. As it was intended as a backup lens it never saw much use until recently, when I decided to give this lens some much-needed attention.

Specifications (f/16 model lens):

Focal length:                        55mm

Minimal focus distance:        0.6 meters

Aperture:                             f/1.2- f/16

Aperture blades:                  8

Lens elements:                    6

Diameter:                            55mm

Mount:                                Pentax K

Built:                                  1970s-1980s

Use

This is one of the bigger standard lenses in the 50mm - 55mm range. Its focus ring turns to the left towards infinity. This may seem a bit unnatural at first for Pentax users as the Pentax lenses turn to the right. Focusing is smooth and in general, the lens has a nice feel to it. I've used this lens with Pentax film cameras and with digital Canon EOS cameras via an adapter. Due to the design of the K mount these lenses do not fit APS-H and full frame EOS cameras much like the EF-S series of lenses. K mount lenses will only work on EOS cameras with an APS-C sensor (crop factor 1.6). 

Images

The images you see below were shot with a Pentax MZ-S loaded with Fomapan Profi Line Classic 100 black and white film and a Canon EOS 90D set at ISO 200.


f/1.2


f/2.8


f/5.6


f/11

As you can see at f/1.2 subject isolation is excellent! Wide open it also shows chromatic aberration (CA) which dissapears when the lens is stopped down. At f/2.8 it is almost gone and at f/5.6 there is no sign of it. The further you stop down, more pieces get in focus until at f/11 all pieces are in full focus. At f/1.2 there is also a bit of vignetting, although the APS-C sensor crops out some of it.

crop of the center of the first photo 

In these shots you can clearly see the paper thin focus area when the lens is wide open. Again wide open it shows CA which is clearly visible at the edges of the coins in the second cropped image. In this shot the vignetting at f/1.2 is quite strong.


f/11

There appears to be some very slight barrel distortion, although the chess board itself is a bit crooked in that sense so it might not be the best subject to judge distortion with.

Conclusions

Overall I really like this lens. It produces dreamy images when shot wide open and when stopped down this lens performs excellent with crisp sharp images. Of couse, this is a 1970s-1980s lens so focusing and setting the aperture have to be done manually. Focusing is tricky wide open due to its very narrow depth of field, I find that I prefer using it with classic cameras that have a split-screen focusing screen. The fact that is suffers from vignetting and CA wide open is unfortunate but can be fixed in post quite easy. When stopped down these are no longer issues. And then there is the price. This is a really  affordable f/1.2 lens. All in all, I find this to be a fine standard lens and I find myself wishing that I had started working with this lens sooner. I'm interested what you think and what your experiences with this lens are. Drop me a line in the comment section below.
