Can you tell the difference? This is entirely nonscientific, harsh night lighting, shot wide open @ f/1.4, ISO 3200, wih the Leica MM (taking color out of the mix; I didn't do any editing to the basefiles; JPEGS uploaded directly from RAWS in LR4)....handheld, no tripod, yada yada
The 3 Leica Asphericals
--35 mm f/1.4 Summilux FLE
--35 mm f/1.4 Summulux Asph (pre-FLE)
--The legendedary 35 mm f/1.4 Double Aspherical (AA)
I will disclose results and my thoughts in after a few responses are in....
