There are still discussions in a German forum that the sharpness with activated VC is significantly related to the shutter speed. A guy with a D810 did more than 600 pics
shooting the same object and found the following.
The majority of pics taken with VR on with 1/125 / 1/160 and 1/200 shutter speed were all unsharp and it were reproducible.
It looks like an unsolved problem up to know. Any suggestion what the reason could
be causing such a problem? D810 or the 300 4.0 PF?
Here is the test I ran today.
Sitting in a lawn chair feet flat on the ground, my elbows stabilized on me knees, and the D800 pressed to my face. Rolled on the shutter button to AF-S and trip the shutter. ISO tweaked from 50 to 400 to keep the aperture in a the f5.6-16 range (except 1/15 where it\'s f22 and 1/20 where it\'s f19). These are untouched, 100% cropped, RAW images.
I\'m a bit concerned.
