well dont be too disappointed, but, as if i needed another example of why i hate cannikon, the good folks over at nikon decided to go against the grain and have its software 'not recognize' any lens attached with a third party adapter. they make their own adapter for nikon legacy glass, everyone else can go to hell!
as a consequence the camera will not allow you to shoot an adapted lens in any but 'mamual exposure' mode. not such a problem, but because the software does not recognize a lens is attached, the in camera aids for manual focus (three step focus zoom) and for camera metering (an on screen gauge that shows under, over and proper exposure) do not work. dont even try, it just doesnt work and its intentional.
the work around is obviously using longer lenses because focus can only be achieved by eyeballing at the lenses native distance. or, thanks to increased DOF of three stops (5.6=f16 DOF), zone focusing. for metering, while the cam locks the shutter in aperture priority, it DOES ttl meter, so a good approximation can be derived there, then move to 'manual' exposure and start the shutter speed at that value, and chimp. or sunny 16 and chimp.
btw, it also means auto iso doesnt work, so you first need to set that manually.
have fun and thanks for nothing nikon.
