So DPP rendering has proven to be faulty, easily corrected by changing High Quality -> High Speed. ACR6.7 is beta and used with DNG converter to edit/view files in LR4. Does anyone else find the pictures in DPP once this setting has been changed to be markedly sharper/vibrant? I know the ACR is beta, but the good news is, that the camera sensor itself is producing great images, although some might have some MA issues with lens, i'm beginning to think all of this hysteria is due to poor rendering with currently available software. Here is a little side-by-side I did with the two current options, the JPG is a poor representation obviously as its just a screen shot but I think you will get an idea. The DPP version appeared much sharper. Albeit the 'test' anything but scientific
