The three contestants are: Sony A7 with Leitz Summicron-R 1:2/35 (Made In Canada, early '70s vintage) Sony NEX-7 w/ SEL24 Canon EOS-M w/ EF-M 22mm pancake lens Here's some full test images: A7 w/ Summicron-R 35 @ f/5.6 35 @ f/8 by Jeff Addicott, on Flickr NEX-7 w/ SEL24 @f/8 by Jeff Addicott, on Flickr EOS-M w/ 22mm @ f/5.6 by Jeff Addicott, on Flickr With some 100% crops from the mid upper left: 35-shootout-upper-centers by Jeff Addicott, on Flickr Is it just me or is the NEX-7 / SEL24 combination getting beaten up a bit at the pixel level? Well, when you get an unexpected result, best thing is to repeat the test. Here's the upper right corner from a different series of shots (focused specifically on that corner): 35-shootout-corner by Jeff Addicott, on Flickr I must say, I really did not expect the A7 with a 40-year-old lens to be leading so comfortably, so repeatedly! Here's a center crop from a test scene at about 5': 35-shootout-center by Jeff Addicott, on Flickr And now the part of the comparison where I sort of expected a bloodbath: the BOKEH test! A7 w/ Summicron-R 35 @ f/2 by Jeff Addicott, on Flickr NEX-7 w/ SEL24 @f/1.8 by Jeff Addicott, on Flickr EOS-M w/ 22mm @ f/2 by Jeff Addicott, on Flickr A7 w/ Summicron-R 35 @ f/4 by Jeff Addicott, on Flickr I repositioned the EOS-M to compensate for the wider lens & smaller sensor. Even with a slight unfair advantage, it trails the pack for BOKEH potential. The full-frame rig looks about the same, stopped down two stops! So there you have it! A few extra notes: The Summicron-R is pretty rock solid for the most part, but I did observe a tiny bit of smearing in the extreme outer corners at f/8. The color response seems noticeably different. And finally, be warned: it is really freaking heavy! The EOS-M is very nice optically and very compact - I routinely throw it in a jacket pocket. This comes at the cost of very slow AF performance and a very awkward interface. Much more frustrating to actually work with than either of the Sonys IME.
