Now if I am right somewhere in my Nikon I can set the shutter speed to rise as the focal length of my lens increases .
This seems a bit obsolete today with VR .
Now what if I could programme the aperture to change with focal length. I could study my DXO sharpness and field map and use the best aperture for that focal length. So at 28mm I might have F4 and then at 100mm change to 5.6 and at 300mm f8.....
OK you say just move the thumb wheel to what you want ....No No they stay taped over ,too often the errant thumb has moved the wheel without permission..!! chimping ? dont do that either.
I once disabled the rear wheel and left it untaped but my wife discovered by pressing one of the rear buttons unknowingly she could then knock the wheel in error and do all sorts of great things to the colour balance !!!! No No tape them up !!!
Useful idea or not .?
