Dx lens on film slr

[borisnikon]

I currently own a nikon d3100 and I am looking to buy a f70, f80 or f90 but I want to know if I can use my current dx lens on it.

Anyone?? I am confused will it work with no autofocus or will it just not work at all? Thanks for the help.

It will probably work however the light from the DX-specific lens will not cover the entire FX sensor.

The lens will work but you are going to get some serious vignetting. Any DX lens is optimized for the APS-C sized sensor, which isn't a full 35mm sensor. Essentially you won't get any pictures worth taking unless you purposely want that effect.

This would happen.

Ok, thank you. So fx lenses would work and auto focus then.

As far as I'm aware, all Nikon film SLRs (from the late 80s forward) have an AF motor built into the camera. So any Nikon AF lens should be able to AF on them. It's only the new 'baby' Nikon DSLR cameras that don't have their own AF motor.

Yepp. My N80 has a (very powerful) AF motor in it, and will meter and autofocus with every lens my D80 will. But DX lenses will have insanely heavy vignetting, as in the example a few posts above this.

Sorry for all the questions but, nikon lenses have either a d or a g on the end of their name. For example: 50mm f1.4d
Does this mean fx and dx or is it something completely different.

D lenses have an aperture ring whereas g lenses do not. G lenses are newer, I believe.

The lens description will say if it is a dx lens. I'm assuming (and I may be wrong) that there aren't any d DX lenses. Could be wrong but I haven't seen any.

Also, the 50 1.4d and the 50 1.4g are both full frame lenses.

Thanks MTVision that explains it...

If its a g lens youl need a f5 or newer, and of course you cant auto focus with a manual focus body.

Some dx lens vignette worse than others, and the amount changes through the zoom range, good news is the effect is visible in the viewfinder So youll know before you pull the trigger.
