To have a 75 MB file from a 50 MP sensor for one-twentieth the price of a Hasselblad is an extraordinary gift. And thats what this camera delivers. The images are sharp as a tack. Theres a lot said about moire with the SR version, but if you look at comparisons between the same scene shot by both cameras, theres still moire in photos shot by the S, just not as vivid, but certainly requiring correction.
Im not concerned about the ISO to only 6400, as Ive never shot a photo for sale at anything higher. Fps are not an issue, as I dont shoot sports. Poor Dynamic Range is talked about a lot, though its the same as the 5D3 which Ive owned since it came out, and there are easy work-arounds that dont involve buying the D810 or the Sony A7R.
Its almost good enough to use as a walkabout camera, but theres a big disappointment there for me. It takes 2-3 seconds for the RAW image to write to even the fastest CF card; JPEGS are a bit faster but even those are slow. I called Canon tech support, and they were surprised when then tested their model that the speed was so slow; they said it was a feature of the camera, not of any settings such as NR.
Its a shame to use this camera only for landscapes or studio work, I would have liked to have thought I could use it in the field generally. Its shame they didnt speed the buffer. Will have to stick with the 5D3 for that. 4/5, not 5/5 for me.
