The 35mm that I use is the 35/2,8 Summaron that we tested vs. the pre-ASPH and the 8-element Summicrons on the Optikos Corporation MTF optical test bench; see the article in LHSA Viewfinder magazine, Vol 37 No 4 (4th qtr 04). Showed pretty clearly that if you don't need the added stop of speed, the Summaron was the choice.
