Left top conner is much worse than centre of this image...
That's why I am ordering this camera with the Zeiss 24 mm and keeping a couple of my CV M-lenses.
There should really be a lot more detail than there is in this image... they need to test this camera with proper glass.
I'm very impressed with the sensor from what I can see.. usable iso 3200 it seems.
Overall very nice. The body and sensor look like they will be stellar. I'm not sold on this lens though. The corners of 7 are pretty ugly. OTOH, there certainly are enough pixels to crop the edges out.
The left corners seem to be much worse than the right... :/ decentered lens?
