Does any one know what would happen if you were to put a digital only lens on a 35mm SLR?

I am not going to do this, I do not want to ruin my camera body and/or lens, but I was just wondering. I have a Nikon D50 and Nikon N65. The D50 came with an 18-55 mm 3.5-5.6 DX lens. All my other lenses I can use on both my cameras, but this one I cannot. I was just wondering.

The Nikon DX digital lenses can be used with no harm on most recent Nikon 35mm SLRs (don't try on an older manual focus camera).

The downside is that you may lose some features, such as VR , AF-S autofocusing, ability to meter, or ability select aperture (G lenses with no aperture ring) depending on the camera. The N65 should be able to use any recent autofocus lens, see here for details:

Given that, however, most DX lenses have a smaller image for the digital sensor, so you will see vignetting or dark corners in your images. Put the lens on your camera and you should see this in the viewfinder. So, the lenses are usable, but you may or may not like the effect!

One exception, however, is the 12-24 f/4 DX, this wide angle is usable without vignetting from about 18 mm to 24 mm on a film camera. It doesn't damage the camera, and it's very useful when I need a wide angle, but only happen to have the DX lens around!

I think the lens is closer to the mirror so it will hit or something like that.

Are you talking about a lens for a digital slr with a smaller sensor than 35mm? I wouldn't try it. Sell it and get yourself a good quality lens.

If the Lens is compatible with Both 35MM SLR and Digital
-Then Yes!! It will work!!

Some Pro Digital cameras work fine with Non-Digital Lenses
(Of The Same Manufacturer)
What separates them is Auto Focusing mechanisms-What did we do before they invented Auto Focus??

The earth would stop rotating on its axis and there would be chaos and destruction. Dogs would run happy and gay with cats. The sky would turn black. The media would report on some of the good things Bush has done. Pandemonium, I tell ya, pure and udder chaos.

The 18-55 DX has a smaller image circle than regular lenses. At the wide end of the zoom, this would result in severe vignetting - like that cheap effect on tv shows when you supposedly look through a periscope.
It would not do any damage to the lens or the N65. And from around 35 to 55mm, you can use it with no ill effect at all.

You'll get dark corners. Just try it on a few shots and see.
