I bought my 50/1.5 Summarit from him...
I'm still of the thinking that ultimately, it's the 50AA for everything that requires great sharpness plus other 50s for specific w/o character. I'm already kind of doing this with the 21s... the Lux for speed and subject/background separation and the SEM for 'perfection.' Yes, I actually walk around most times with both. But there is so much more variety of 50s, it would be easy to bring along several just for each's look.
If you're willing to spend the $$$ on the 0.95 Nocti, then for the same money you could get the 50 AA and a bunch of vintage 50s to give you much greater variety of rendering options:
50 Lux pre-ASPH
Joe, that's interesting about the pre-ASPH, but also probably how I would use it mostly - portraits, etc. For far distances the Lux ASPH is great, though almost certainly topped by the AA.
