You can consider me impressed.

As some of you remember, I got a Carl Zeiss Pancolar 50f/1.8 – 8 aperture blades, zebra version, the so called “radio-active” version. This one is significantly different lens compared to the subsequent 6 aperture blades, zebra/MC versions. Have a look <here> this page has all the information you need about the Pancolar.

I sent mine to Luton cameras to have it serviced. When I got it back I thought I should compare them to the Takumar 55f/2 and the two different versions of Helios I have (44-2 and 44-M4). I will leave the pictures of the 44-M4 out of this post as most came out soft and slightly out of focused. The only one that was acceptable was one shot at f4. I suspect I have a faulty sample.

Most of us are familiar with theTakumar 55 (f/1.8 or f/2). It is an outstanding lens, very difficult to criticise it. Sharp from wide open, gets sharper when stopped down, very nice out of focus area. On the other hand, the Helios 44-2 enjoys a lot of popularity on the internet due to it's swirly bokeh and good sharpness in the centre. Once stopped down centre gets sharper but edges will never impress you. Personally, I have never been a great fan of the Helios although I have used it a lot in the past and gave me some pictures I really like.

The Pancolar is what you will get if you marry Takumar's sharpness with Helios' character. The biggest fault I find with the Pancolar is that due to slight yellowing, it is the most difficult of the three to focus. It might not seem like a lot of yellowing but with cameras and dark focusing screens, it is noticibly more difficult to focus.

All pictures are shot with the Praktica LTL and an Agfa APX100, developed in Rodinal. Many thanks to my ever-willing model which doesn't miss a chance to pose for me every time I get a new lens.

First picture is the Pancolar, second is the Takumar, third is the Helios.

All lenses are wide open – that is the Pancolar is at f/1.8 and the rest at f/2. The Pancolar has slightly better contrast (possibly due to the slight yellowing) and i think it renders a bit more detail. The Helios swirls around like a washing machine – nice effect but you can get tired of it quickly. The Takumar is more neutral in this respect – there is a slight swirl but not too much. The Pancolar has a swirl but if you stop to f/2.8 it goes away completely.

At f/4, the difference between the Takumar and the Pancolar is negligible. Both are very sharp although I think the Pancolar has a slightly more contrast and tiny more detail (or not?).

I absolutely love the character of the Pancolar when using wide apertures. There is a slight glow but is plenty sharp. The swirl is not always obvious as you might think.

By f/2.8 the lens is very sharp and contrasty. It renders highlights so nicely.

Together with the Zuiko silvernose 50f/1.4 and the Rokkor 58f/1.4, I consider the Pancolar as one of the most characterful lenses. But unlike the other lenses, the Pancolar keeps a very nice balance between having character and being a sharp and contrasty lens.

Very nice. I also have a thorium Pancolar I purchased to go on my Pentacon Super as the 55/1.4 is “out of sight$”. Had it serviced a few yrs ago as it had sticky aperture blades, but by the time I got around to trying it out, the issue returned. Don’t think my service provider did a good job as obviously the focusing lubricants came back very quickly. I relied on the use of an earlier Pancolar 50/F2, which is very nice indeed.
Maybe I’ll eventually get the F/1.8 sorted out , and find the same satisfaction as you have…

The only solution is to complete disassemble, remove all old grease and relube with new synthetic grease that doesn't migrate to other parts. I was tempted to do some of the advice found online but eventually I went for a full service.
 
The Helios 58mm has enjoyed a certain fame, especially thanks to many videos by influencers, who have praised its performance. Many enthusiasts have purchased them and now have poured them onto the market, so much so that they are found for little money.
I have had almost all versions of the Helios 58mm (44M; 44M2; 44M4, 44M6 and 44M7) and I found interesting for the performance (not for the bokeh which honestly does not interest me) only the M4 and M6 on B&W film. I find the Takumar to be from another planet. I used the Pancolar with satisfaction on an Exakta Varex, I think the scheme was 6 lenses in 6 groups, the performance was still excellent.
 
I’ve used the Helios 58 for the same reason. It’s sharpness and character, not per se it’s swirl.

The Soviets improved the glass and the resolution with each new version, but kept the focal length of 58mm

It is important to know that each lens element has to be individually centered with special equipment on the Helios. (If you take them apart to clean them) I recommend to leave them alone as much as possible and only unscrew the front and rear group when cleaning the aperture.

This is when a lens gets an unsatisfactory performance after service.
 
Got me thinking about my radioactive super takumar.....yes, yes, I know it's not the same thing as pancolar. It's just that you guys got me thinking about the sharp vs. bokeh I can see in one of my few radioactive lenses. I don't remember what my Exakta 50mm lenses are. Haven't looked at them for a really long time. Heck, I might have one of these Pancolars. I'm going to go look when I get home......
 
Very nice lens you’ve got! I was on the spending spree and now have quite a few M42 primes - Helios 44-2, Helios 44M, Helios 81 automat (converted to M42) and my old Super Multi Coated Takumar 50/1.4. Now the project is to test them against each other. I made a few shots via adapter on Fuji X-E1, but APSC sensor does not give a good idea how swirly (or not) the image is. Sharpness wise they are quite similar (without pixelpeeping).
 
After I picked up my later model one a few months ago for peanuts and found out how nice it can be, I looked for more versions but I'll never buy one this cheap ever again it seems....Some of the prices are 🤪 😉
 
There are other M42 lenses in the 50mm range that are interesting, even if in some respects inferior in sharpness to the Takumar: I'm thinking of the Yashinon 50 1.7 or the Mamiya 55 1.8: the latter in particular has a character all its own with a rather "vintage" rendering. The Yashinon is certainly sharp already wide open but its bokeh, in my eyes, is not at the level of either the Pacolar or the Takumar (although here the discussion is less objective).

The Yashinon is excellent! Isn’t it radioactive too? Mine has turned yellow…
 
Just to satisfy my curiosity, I read that the images were shot on APX100 film. Could I ask what your development and especially drying process is?
The images don't appear to show traces of dust, which are normally always found on films developed at home (but also in laboratories).

Pan, it’s lucky you are not trying to sell these lenses - no man’s wallet would be safe!

And if that’s your own daughter, you are a very lucky man. Mine went permanently camera-shy at 12yo.

There is this one on FB marketplace, Cannock area. I exchanged a couple of messages with the seller, it is the second, non-radioactive Pancolar sn: 89-something) but I think it's good for £50. I am not sure where about in UK you live though.

I decided to pass as I prefer my lenses glowing in the dark.

Edit: yes that's my younger daughter. The older is 15 and is camera shy - I have to beg for a portrait.

Sorry Alberto, I just saw this comment. I will have a look on the comments I wrote on the negative sleeve and let you know.

Tempter! But no, I’m not going back to SLRs … although I helped my daughter choose a Pentax MX recently, and I was a little bit envious. 😬
