The pixel pitch is the same as the one of NEX-7. Do not forget that we have also about 24% smaller image all over. If you produce the same image size with smaller sensor, you will have a loss, here we have 24% less image surface to cover.
IQ is absolutely amazing, Sony sensor performs excellent and IQ difference on APS-C is not noticeable. On the other side, is the DOF factor, it is hard to get good bokeh with a 4/3 camera. Maybe it is a reason for Voigtlaender to make Noktons with 0.95 to get DOF ranges that look good. I have compared 4/3 to APSC, found not that the IQ was less good, but with any 2.8 lens, I had good DOF and bokeh on the NEX-7, while on the 16mpix 4/3, it was almost impossible to get any blur. For tourism, family, and travel, I prefer a 4/3 format, on those events you want all sharp on the picture anyway. Now, concerning this camera, it has good features, is a bit too big for a mirrorless, and is salty priced, not exactly the way to go if you expect massive sales.
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
