Again...

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.

Shutter speed / Sharpness

20 / 70%
40 / 80%
80 / 80%
100 / 40% !
125 / 15% !!!
160 / 10% !!!
200 / 20% !!!
250 / 80%
320 / 70%
400 / 80%
>500 / 95%

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?




How is the percentage of sharpness determined? You mentioned they were all not sharp?
