bocaburger Posted May 16, 2012 Share #7 Â Posted May 16, 2012 Advertisement (gone after registration) All my Leica lenses (mostly Mandler-era) are as sharp as I need. I draw the line at the point where the quest for bleeding-edge sharpness results in a hemmorhage of my savings. Link to post Share on other sites More sharing options...
farnz Posted May 16, 2012 Share #8 Â Posted May 16, 2012 Difficult to choose between the 100/2.8 APO-Macro-Elmarit-R and the 90/2 APO-Summicron-M asph beyond 2 metres but both reputedly bow to the 280/4 APO-Telyt-R on pure sharpness if that's your 'thing'. (Incidentally, I also own the 50/1.4 Summilux-M asph and while it is the best corrected of them all it is not as sharp as any of the three to my eye.) Â Pete.

sdk Posted May 16, 2012 Share #11 Â Posted May 16, 2012 Really high resolution and contrast wide open or 1 stop closed: 25mm/2.8 Biogon ZM, 24mm/3.8 Elmar M ASPH, 28mm/2 Summicron M ASPH, 28mm/2.8 Elmarit M ASPH, 35mm/2.8 C Biogon ZM, 75mm/2 Apo-Summicron M ASPH, 90mm/2 Apo-Summicron M ASPH. None of these is probably quite as good as the new 50mm Apo, but the 35mm C Biogon and 75mm and 90mm Apos are probably closest. Link to post Share on other sites More sharing options...

rramesh Posted May 18, 2012 Share #16 Â Posted May 18, 2012 At what point does 'Sharp' become 'Too Sharp'? Link to post Share on other sites More sharing options...
IWC Doppel Posted May 18, 2012 Share #17 Â Posted May 18, 2012 At what point does 'Sharp' become 'Too Sharp'? Â I had an interesting conversation with one of the guys at Leica and he spoke about film grain size and the impact on apparent sharpness. I think most know what sharpening does when you adjust in LR or other. seems the grain size, picture size and lens, camera resolution all play a part. Â The feedback on the APO was very good, he said it's amazingly sharp but in a very natural way. Â Too sharp for me is either looking unrealistic or compromising the over all look. I really love the way my 50 Lux paints images and forgive it every time for the lower contrast at f1.4 and the slight softness. Â I also wonder if there is possibly some synergy in a positive or negative way with a digital back and a lens that is as we all know not quite perfect !

On numerous occasions I have exhibited (and sold) 1700 x 900 landscape prints produced from this lens - each of them magnificently pin sharp. Over the years I've had both Canon and Nikon kits with prime lenses - none of which have come anywhere near to this standard. Link to post Share on other sites More sharing options...

lct Posted May 18, 2012 Share #20 Â Posted May 18, 2012 None of my M or R lenses have MTF charts similar to those of the 50/2 asph. Great glass like 50/1.4 asph, 90/2 asph, 75/2 asph or 28/2 asph don't play in the same league from this standpoint. In fact i have only one lens which is comparable to the 50/2 asph on charts, the Apo-Telyt-R 280/4. Link to post Share on other sites More sharing options...
