Converting

[Hgarrett]

I was thinking of switching to Canon , I now have a Nikon d2x . But the thing is I don't want to sell my lens, with the lens adapter will i be able to use the nikon lens on a canon 5d mark ii. Is there any negatives to switching? Does the lens adapter causes distortion/vignette?

Keeping old Nikor glass is a good idea. That way when Nikon comes out with their next body you will already have the glass. An adp will work with 5Dii really well if you buya good adapter. Just remember no auto focus or auto anything else.

Any adapters that you request ?

Why a 5DmkII?

I have no nikor glass so I know nothing about suitable adapters. sorry

If all your lenses are F-mount, not G, you should be able to adapt them (you need some way to control the aperture--if the lens doesn't have an aperture ring, you're stuck shooting wide open). I don't think I've heard of any 5D mirror-clearance issues with Nikkors (I do know that with some Contax lenses, the rear element can stick far enough into the body--particularly with wide angles--to hit the mirror when they're adapted, but the Nikon F-mount has the longest image-plane-to-flange distance of all the mounts).

The main thing is that you're going to lose all communication between the body and the lens. Your EXIF focal length and aperture fields will be empty. You won't have aperture control--which means stop-down metering. You can only shoot in M or Av. You won't have autofocus. It won't be the same as simply slapping your lenses onto another Nikon dSLR; you are going to be giving up quite a bit of function. If you used to shoot an all-manual film SLR in the old days, it's a piece of cake, but if you're used to auto-everything, it can be a bit of a stumbling block.

But yes, a simple adapter ring (F->EOS) will work.

The best "adapter" for Nikon lenses to a dSLR, honestly, is a D700.

Wide open or fully stopped down? When a G lens is removed from the body, it stops right down to minimum aperture.

I have been shooting manually so I'm perfectly content.

But so when you say open wide with the lenses without a aperture ring what do you exactly mean?

Most new Nikon lenses dont have aperture rings so you have to control aperture with the body. On your D2x, that's done with the front scroll wheel. Thing is, putting a Nikon lens to a Canon body, there's no way to control the aperture, so it automatically defaults to wide open and cant be controlled.
