Re: "Lossless Compression" creates artifacts in A7r
I think this thread may be on to something.
I didn\'t have a Coke bottle, so I was forced to take a picture of my cat. I converted it to a DNG and back and forth from SRGB to ProPhoto a few times as that is my workflow.
Looking at his whiskers at 800% it\'s clear that there are some strange pixels there. I\'ve looked at it on my 30 inch calibrated Apple Cinema Display, as well my Google Glass and a Zenith TV and even when I turn my head sideways the pixels are still there.
Regretfully, I\'ll be returning the A7R not only due to this defect, but also because of the \"crap\" implementation of exposure bracketing. Not to mention that the shutter shock is giving me carpal tunnel syndrome.
On top of al this, the camera is an ugly shade of black. My colorimeter measurements of the battery cover show RGB values of 1,2,1 not 0,0,0 as you would expect if Sony had any idea how to dye plastic. Of course I made those measurements in the Northern Hemisphere, so I plan to redo them in the Southern Hemisphere later today to double check.
Anyway ... see for yourselves .... WHO\'S CRAZY NOW, HUH?
