Last summer in Alaska I carried both the 645Z and the K-1. Both made good photos. Both had lots of shadow detaiI. Each has its advantages and disadvantages, but I don’t think IQ ultimately discriminates between the two. Maybe a slight edge to the 645Z. I am not going to do any sort of technical comparison myself. However, I am quite sure I have a few mountain landscape sequences where I used one camera for a few shots, adjusted composition slightly, did a few more, left the tripod in place, just switched to the other camera, did a few more shots… So I should have some shots done under similar/identical circumstances as far as lighting etc are concerned. Of course the lenses will be different. If anybody wants to explore an IQ comparison with those images, I can send you the original DNG files. Do note that they were not shot with such a comparison in mind. E.g., the shots I am thinking of, I likely was using the D FA 24-70 on the K-1 and the FA 150 on the 645Z. If anybody wants to spend time on this I will dig out some sample images and put them in Dropbox with a link posted here.
