You can click to get 100% image, but jpeg is in 30% compression, its file size is still 1.2MB.
See the shot by G-Sonnar 90mm > http://www.pbase.com/kkawakami/image/69121574/original
This lens seems sharper, but bear in mind this has larger magnification due to M8's crop factor.
And also this was shot at f3.5 w/o LPF, whereas G-Sonnar 90mm's shot was at f2.8 by EOS_5D.
(LPF = Low Pass Filter for sensor) ... Btw this is M8's full-size image.
