Afternoon Utak,
We are thinking very alike on this. Several years ago, I was originally thinking about an 85. Wondering what to do - the FA 85 was expensive and too fast for my needs. I was thinking about the CZ at f2.8, but I really did not want to go through the trouble of swapping mounts. Then I saw the SuperTak here on the Marketplace and acquired it. If I were trying to acquire that very lens, it probably would not have happened. Wonderful lens, and it is very heavy (not a problem at all) - just metal and glass - it actually feels wonderful - especially for a 50 year old lens. I tend to wind up shooting in the dark, so with the M42 adapter, I was always fishing it out of the camera to swap lenses (I guess I should just have "permanently" mounted it on the lens). So, I turned around and found a CZ and swapped the mount. Now, I have two fabulous lenses - each with their own exceptionally fine character. Actually even though they are both labeled as 85's one is a bit wider (shorter) than the other.
That is probably why I have not done anything with the 85's. It just seems to be so wrong, and did not feel "right". So, I have just been doing nothing.
Even though I shoot landscapes, I have been picking up longer primes. My other though is to sell off my old kit lenses, along with several 50's that I don't use (M 1.4, M 2, A 1.7) and consolidating with a FA 43 or perhaps the 77 - I can't decide (I can kick that can down the road). I'll always have my Tak 55/1.8 on my Spotmatic II that I have had since 1970 - it will never go anywhere else.
Actually, I have now decided on an approach. The kits and 50s go, both the 85s stay - that feels like the right and best decision. That will make what goes into the bag a much simpler process.
