Very interesting, thanks for posting. Wondering why the D800 resolution (or 'sharpness') is so relatively low (about the same as the 24mp A7)?

Seeing this data raises a number of questions in my mind; unfortunately I lack the technical background to even begin to answer them. I will be watching what you gentlemen and the other experts discover with great interest. There may be implications for everyone in this.

Another mFT camera with a serious shutter shock issue (I assume) in the new comparison tool is the Panasonic G6. Seems to be even worse than on the E-M1. Could probably have been avoided if DPR had used the optional electronic shutter on G6. Olympus E-P5 and E-PL5 are affected too, but it doesn't seem to be a problem on the (also mirror less) Fuji X-E2 and X-Pro1. Can't spot any problems on Canon and Nikon DSLRs, except maybe a bit with the D5300.

One thing that concerns me; if this is shutter shock vibrating the sensor, external damping (heavier tripod, draping the camera body on the tripod with weights, etc.) may not be of much help.

I do wonder; how could high-end camera manufacturers, with vast resources for testing, possibly miss an engineering problem like this with a potential for degrading the value of their premium products?

More data!
