It may , however, be of interest to those of us who like optical excellence whatever the source may be. 2 full-frame shots: taken with a Macro-Elmar 4/100mm and a Yashica ML 2,8/55mm Macro both at f8, Canon 20D at ISO 100, tripod mounted, daylight. http://gallery.leica-users.org/album150/Leicaf8_full_frame http://gallery.leica-users.org/album150/CY_full_frame 2 centre crops from the same shots http://gallery.leica-users.org/album150/Leicaf8 http://gallery.leica-users.org/album150/CY_f8 I think that the resolution of the Yashica is superior but the clour rendition of the Leica is better (richer). Just to make sure that the lenses were comparable they were both cleaned, front and rear elements, before taking these. I ran the test through 5 times and got the same results for f8 and for other apertures, refocussing each test series to eliminate any possible focussing errors, and picked the best of each run. Maybe I got a duff Elmar, this difference in quality is surprising to say the least. Cheers Douglas BTW it's a Miners Safety Lamp
