Now that we're seeing actual results and feedback from owners there's a lot of rejuvenated interest in this lens, which now seems to be approaching the highly regarded status of the 35mm f1.2.
I disagree - while Nokton 50/1.1 may have some followers - it's nowhere near the 35/1.2 one following. Why? - it's not as good. Ok, now , please , all the Nokton 50/1.1 owners (or sellers) - dont get on my case about it. I'm not saying it's a bad lens - just there are others that are cheaper and better.
I too was excited about it BEFORE it came out, I didnt like what I saw from it originally and still dont like most of the images I have seen from it. Purely personal thing, mind you. I like and own several CV lenses and to me - if you had to by a 50mm lens made by CV - it's always a Nokton 50/1.5 . Far better value and I like images from it way more. When I got me a Super-speed 50mm lens - I first got a Canon ltm 50/1.2. A very good lens I think. Old, has some faults, but I liked it's character. When I decided to spend the money for a "perfect" super fast lens - well, nothing really came to mind other than Hex 50/1.2.
So, opinions vary - but if I had to advise a fast CV lens - it would be 50/1.5, 35/1.2. or 35/1.7.
As far as Heliar goes - I used to have a 50/2 version and while it was not bad and had it's character - I just have way too many other 50mm lenses I like better. And if I need a slow collapsable one - I have a russian Industar that I like just fine.
So, if I had some money to burn - I'd get something challenging - like a CV 15 or even 12mm lens. Those are fun and photos I have seen from them impress me far more than ones from either Nokton 50/1.1 or Heliar 50/3.5.
