Karpman does the D50 have an internal AF motor, it'll be in the specifications in the manual. Failing that call Nikon and ask.
I used my Tokina 400mm on a D90 and D300. As far as I'm aware Nikon don't usually suffer with focussing problems using some older lenses in the same way that Canon do. It would'nt
af on a D40, D60, D3000, D5000 of course. I've used lots of older second hand lenses and the only time I ever had a problem was with an old Sigma 400mm prime on later Canon bodies. When using a TC it generally depends on the speed of the lens whether AF will operate. Using a 2x on an f2.8 or a 1.4x on an f4 should'nt be a problem.
Ok give in lol
Gonna get me a nikon 300 f4 af, If i get the non AF-S version it won't autofocus with a TC?
anything else i should know before i plunge, Ill maybe have a tokina 400mm that is un usable LOL
/slaps self
karpman
why wont it AF with a 1.4? Either in this thread or one of you others I did say that my 300/4 IF-ED worked well with a Sigma 1.4tc, the AF-S also works extremely well with a 1.4TC
Cant use a Nikon with the non AF-S lens as it doesn't have a mechanical pass through, I only ever used it with a Sigma TC but Kenko should be okay, someone else may be able to talk Kenko
