I was waiting for this release for a good while, having allot of hopes as i am Canon shooter on crop for the moment. I own Canon EF and EF-S lenses and vintage glass, M42 Carl Zeiss, Pentacon and C/Y Yashica ML lenses. This release is the decisive moment to choose between Canon body or Sony in stepping up to full frame; IBIS and focus peaking were my main expectations from this camera along EF (and EF-S) compatibility... also custom buttons. I will wait till the official announcement but It appears i am forced to choose Sony. The 1 card is not really a main deal braker for me, yet i find silly that after Sony responded to the market feedback implementing redundancy in all new FF cameras, the industry giants just ignore this fact... I am tempted to feel more confident in a company that listen to the customer feedback and needs, compared to companies that do what they want. I am not a fanboy of any brand, i just need specific features. I will probably stick to Canon glass since is good and less expenssive than Sony glass.
