So I attempted to buy the new Nikon AFS 300/4 PF ED VR today, for the third time. This seems like an odd thing to write, so please hear me out. Every sample of this lens I’ve tried, on every D810 body (now three of each) produces very strange double-image artefacts only with VR on. With VR off, the optics look consistently excellent. With VR on, I couldn’t get a single sharp image regardless of drive mode, shutter speed, EFC on/off, tripod or handheld. The funny thing is that I did not see this on any other body than the D810: the D800E was just fine with VR on, as were the D3, D4 and D750. I initially ruled this out as sample issues or QC, but now that I’ve tried several lenses from different batches and from different country stock with a range of bodies, I think there may be something much more serious afoot. I have reported my findings to Nikon and they are investigating…
I can only hypothesise that there is some very strange interference going on between the VR mechanism and the D810’s shutter unit. It appears plenty stable in the viewfinder – perhaps moreso than any other lens I’ve mounted – but the results are unusable. Is anybody else seeing this with their lenses, or is it just my bad luck with every sample and body?
There is a folder of full size samples here on dropbox.
