This GDR lens made by CARL ZEISS JENA is very simlar to the famous ZEISS Pancolar because of its symmetric double GAUß construction of 6/4 elements.

++ because multi coating nearly no flare

++ very high sharpness at f 5.6-11

++ fine color rendition

+ good correction of CAs

very highly recommended

Lens Review Date: November 4, 2021 I can recommend this lens: Yes | Price: $30.00 | Rating: 9 

Pros: Close focus 0.33, Bubble bokeh, metal, low price,clear at f/4
Cons: There is a plastic part to the focusing ring I had made a metallic one.

Is very sharp easy to use I had made a 4k video all shots at f/1.8 iso 200, auto mode 4k 30p with YI-M1. Because the sensor is cropped the lens are like 125mm.

Pros: Close focus, Creamy bokeh, all metal, low price
Cons: m42 (maybe not a con?)

Wow. Just wow. Picked this up on ebay after seeing various rave comments online. I own the 1st final version (with PENTACON electric 1.8/50 MULTI COATING on front ring, and one metallic ring on focus ring).

This thing is great for close focus and creamy bokeh. Flowers, portraits, nature close ups. It captures colours vividly and has a great contrasty feel in a lot of shots.

Some have said it's quite soft, but IMO the sharpness and focusing is actually very good. I haven't checked corners or 100% crops a lot - personally I think fixating on those things is a dead-end for 99% of photographers. Photography is art... and this lens is truly an art lens.

I've not tested it hard in bright light situations - so cannot speak about the flair. However a rew times I've used it in light situations, a hood or shade has been more than sufficient most of the time.

My focus ring is rather stiff - I hear that many of these models can become harder as the grease slowly bakes hard over the decades. But it's perfectly usable.

This picture is the "dreamy style with bokeh" lol.

For the price, this is one of the best value lenses I own.

Lens Review Date: December 25, 2019 I can recommend this lens: Yes | Price: $30.00 | Rating: 9 

Pros: Minimal focus distance, bokeh, sharpness, price value
Cons: focus
Sharpness: 9    Aberrations: 7    Bokeh: 9    Handling: 7    Value: 9    Camera Used: K-5   

My copy seems to have an issue with focus from far distance, it stops at around 6 Meter at infinite

However since I bought it for close up's and portrait it does it job.

Simple love the bokeh and the effects it brings in non standard light and wide open at 1.8 - 2.8
From 4 on its really sharp like any excellent 50mm you dream of.

Worth each cent :-)

Lens Review Date: September 29, 2018 I can recommend this lens: Yes | Price: $15.00 | Rating: 10 

Pros: sharpness, contrast, color, bokeh, close-focusing
Cons: not as well made as Takumars
Sharpness: 10    Aberrations: 10    Bokeh: 10    Handling: 8    Value: 10    Camera Used: Sony a7   

I've only had this lens for two days, and the aperture needs to be cleaned and relubed, but it's already a favorite and my flower lens. Until I can tend to the aperture, I'm shooting with it wide-open and often at minimum focus distance. It's extremely sharp wide-open and has great contrast, renders colors very well and has the creamy bokeh I like. My copy was made in 1958 and has only a single coating but that might be an advantage as far as contrast goes. I found it in a shop in Arequipa, Peru. The seller wanted $50 but readily accepted the $15 I offered.

Lens Review Date: June 21, 2018 I can recommend this lens: Yes | Price: $40.00 | Rating: 8 

Pros: Minimum focus distance, quite sharp, unique bokeh (smooth with bubbles), cheap
Cons: Build quality is not as good as other vintage lenses
Sharpness: 9    Aberrations: 8    Bokeh: 8    Handling: 7    Value: 10    Camera Used: Olympus OM-D   

Bought this lens "by accident"... It was in bad conditions, focus ring was very stiff. But I tried it and liked the results so much that I bought another one.

I only used it on a micro 4/3 camera because I wanted to play with the good minimal focus distance, it's funny on a 50mm but really amazing on a 100mm equivalent !

Sharpness is quite good even wide open. A bit of chromatic aberration. It becomes very sharp when stopped down.

Bokeh is smooth, but it can also be distracting because the lens tends to produce funny light bubbles sometimes. It is also quite prone to flare.

Build quality is not the best. Still ok for a 40$ lens, but it is not up to OM, Nikkor, Pentax or even other m42 standard. It's usually dusty and diaphragm can become oily, be careful when buying.

Price is given in € for a used one in good conditions.

Lens Review Date: July 16, 2013 I can recommend this lens: Yes | Price: $23.00 | Rating: 9 

Pros: Resolution,colors and a fantastic bokeh esp. at f/1,8
Cons: none significant
Sharpness: 9    Aberrations: 9    Bokeh: 10    Handling: 9    Value: 10   

Superb at f/1,8 for a slight soft halo effect and a killer bokeh.
Very sharp stopped down with minimal CA.
A very underrated lens which in my opinion isn't that bad built.
Metal construction which after some 35 years is handling very well.

Pros: Sharp, decent build, f1.8
Cons: Needs to be stopped down a bit ...
Sharpness: 7    Aberrations: 7    Bokeh: 7    Handling: 7    Value: 7   


Another thrift store find ... almost new appearance and in its original box. Acquired so inexpensively that I am not going add this info to the database ... I paid less than $3 for it ... actually 2€!

Overall a decent lens that I will have to test outside soon. Until then and based solely on indoors test shots, I'm giving this lens a "7" grade across the board ... and will post samples soon.

Lens Review Date: March 11, 2013 I can recommend this lens: Yes | Price: None indicated | Rating: 8 

Pros: Extremely sharp, close focusing distance, built like a tank
Cons: Very difficult to properly focus
Sharpness: 9    Aberrations: 8    Bokeh: 6    Handling: 3    Value: 8   

I basically stole this from an old film kit of my father in law (hence the 0 $ price), along with a Pentacon 200mm tele, and I use it on a Pentax K-x

In order to focus from closest to infinity you must really work on rotating that damned ring, which takes any kind of spontaneous photography out of the question. On top of that, focusing with the lens stopped down at 11 or higher in anything but direct sunlight is basic almost guesswork, the camera is unable to confirm any focus and you can't see it either. To add insult to injury, after you manage to catch focus you have to do the whole exposure procedure which takes another second or so. So basically, the use of this lens is limited to static subjects (that almost excludes children entierly).

The bokeh gives me mixed feelings. Wide open it's soft and ok but the DOF is very narrow and difficult to work with. Stopped down the bokeh becomes rather nervous and unpleasant for my taste but DOF improves significantly.

That being said, when you do manage to get the entire procedure done, exposure is spot on and focus is correct, the results center frame are spectacular. The sharpness is simply brutal. I have used it to make two female portraits with it and the result was invariably outrage. The details were so perfect, down to every pore and otherwise invisible hair, I was asked to delete forever the pictures. As sharpness goes, I have never seen anything like it. My 40mm Limited pancake is frustratingly soft in comparison.

What I really don't like about it the corner resolution. For any pin-sharp center image, around F5,6 to F8, the corner resolution is simply abysmal. The branches of a tree nicely framed fade to hysterical double shadows towards the edges.

Simply put, if you can wrestle with it, you can get the right exposure and focus, you have the perfect light source and you are concentrating on one subject in the center of your frame, it's a great lens. For anything else, try not to throw it out the window in frustration.

Lens Review Date: December 31, 2011 I can recommend this lens: Yes | Price: $38.00 | Rating: 8 

Pros: Sharp, f1.8, cheap, quality build, great portrait capability
Cons: stop down, 50mm rise to 75mm at APS-C
Sharpness: 9    Aberrations: 8    Bokeh: 9    Handling: 9    Value: 10   

This MF lens is excellent for it's price! My lens is M42 screw mount so I need an adapter M42-->Pk. There is no problem to use it.

Wide open it is a little soft, but still good IQ.
Focus ring is nice and smooth, but too long (turn over 360 deg)
Aperture ring very precise and easy to use.
Good in low light conditions
Great feeling for manual focus
Great correspondence with camera (K-r)

It is hard to focus while aperture is set to narrow because image is too dark. Camera set light automatic but always it is too dark (step down problem), so the best way is use it in full manual mode or Aperture priority mode.

Pros: Min focus distance of 1,1 feet; generally pleasing bokeh; almost no ca
Cons: Cheaply built; a bit soft wide open.

Biggest problem with this lens is its cheap built quality. The aperture ring of my copy does not click in at all anymore; there's no "feeling" at all left while changing the aperture. I have an earlier version of this lens which is also cheaply built.
Both lenses do function though.
I generally like the bokeh of this lens; it is busy but nevertheless appealing. Only on some occasions I find it to be too busy. The making of close-ups of flowers with this lens is a pleasure; I really like the soft focus kind of touch this lens is able to give to the scene as a whole while photographing flowers. Wide open the lens is a bit soft; stopped down to f2,8 it is sharp. The min. focus distance of only 1,1 feet ads to the pleasure if making close-ups.
If you can get it cheap, I would recommend it!
