lct Posted July 30, 2010 Share #21 Posted July 30, 2010 Advertisement (gone after registration) At .7 meter subject distance i would have expected less DoF (2 cm?) and less sharpness as well but i may be wrong. Lux 50 asph, f/1.4, one meter (R-D1). Link to post Share on other sites More sharing options...
Advertisement Posted July 30, 2010 Posted July 30, 2010 Hi lct, Take a look here M9 50/1,4 ASPH and close range sharpness. I'm sure you'll find what you were looking for!
GlennB Posted July 30, 2010 Share #22 Posted July 30, 2010 LCT, You are aware, I hope, that the M lenses have NO electronic data transfer of the f stop or focus distance to the M8 or M9 body ?!? Even if the M lens is 6bit coded (which is only read via IR light, not electrical contacts), only the lens Model is read by the body. The f stop value is ONLY Estimated (calculated approximately, ballpark guesstimation) for the exif information on the M system. The M8 & M9 are Not the same as D-SLRs. Now,,,, back to the original discussion !! Link to post Share on other sites More sharing options...
UliWer Posted July 30, 2010 Share #23 Posted July 30, 2010 Just a quick comparison between the 50-lux asph and the 2.8/50 Elmar(the former benchmark for Leica 50mm lenses at close focus), both at 0,75m with M8, 100% crops f/1.4: Welcome, dear visitor!

farnz Posted July 30, 2010 Share #24 Posted July 30, 2010 At .7 meter subject distance i would have expected less DoF (2 cm?) and less sharpness as well but i may be wrong. Lux 50 asph, f/1.4, one meter (R-D1). DOF at 0.7 metres and f/1.4 is 69.3 cm to 70.8 metres (1.5 cm) according to Leica's datasheet for the Summilux-M 50 mm f/1.4 ASPH. DOF at 0.7 metres and f/2 is 69.0 cm to 71.0 metres (2.0 cm) so it's going to be very hard to distinguish between DOF at f/1.4 and f/2. Pete. Link to post Share on other sites More sharing options...
hoppyman Posted July 30, 2010 Share #25 Posted July 30, 2010 The photographer said that the shot was taken with the lens wide open and the aperture value recorded in the EXIF for the M8 and M9 is an approximation using information from the brightness sensor. It is not an accurate recorded value the way other cameras with electronic lens interfaces do it. EXIF says f/2 no? Link to post Share on other sites More sharing options...
Leicakillen Posted July 31, 2010 Author Share #26 Posted July 31, 2010 UliWer - thanks very much for these images. I would say your Summilux is doing a very good job and is better than Elmar, also notable improvement when going from wide open to 5,6. This is good news for me - I will continue to try with my Summilux. Thanks /Anders Link to post Share on other sites More sharing options...
