The question is (and no one knows the answer) is what percentage of shutters have actually had a problem. Obviously enough to make Nikon consider a recall; but perhaps its good after sales in that they are replacing shutters which have no issue at all. Has anyone here actually seen the "image shading from shutter" that Nikon are recalling the D750 because of? Its a bit of "damned if they do; damned if they don't".I guess Nikon need to offer a good after sales service given that their QC is poor resulting in recalls etc
