FX body can fix DX lens no issue. Not like Canon EF-S, which needs some slight physical mods or something (C users, correct me if i am wrong). Just set your body crop mode to manual.

Currently only the 35mm f1.8 DX lens is very usable on a FX body. Seen the samples, sharp like heck even wide open at 1.8, but really has a bit of CA issue.

Sigma designates the moniker "DC" on its lenses for cropped bodies.

Sigma 50/1.4 is full frame.

For Nikon bodies, there shouldn't be any problem. F Mount.

DG ideal for full frame bodies and DC as 2100 said.

In the past, I thought I could live with DX, so I invested in a few expensive DX lenses... But I finally decided to moved to FX primarily because of its potential, and I had to sell all the DX stuffs so I can get FX lenses. Not that DX lenses cannot be used on an FX body, but it kinda defeats the purpose.

Think wisely!

Why use DX lenses on FX body?
Besides sharpness, you should look at the contrasty level and colour of the images, which I think DX lenses can't replace FX lenses for these on a FX body. FX lenses are also more solid built with weather and dust sealed.

Emergency backup lens when weight is an issue.
Nearly happened to me when I was overseas before and not near a Nikon svc centre.

Actually the performance of the lens does not depend on whether its designed as a full frame or cropped frame. You might be reading too much into it + generalising. If that's the truth, users can throw away their CF Canon/Tamron/Sigma (some of which are better than Nikon FF glass btw). :bsmilie:

Anyway you are not supposed to use cropped frame glass. Plus only Nikon's 35/1.8 performs satisfactorily afaik, the others are phyiscally (as in serious blackouts in the corner, don't even call them vignetting). So your question is like "it will never happen". Can men give birth? :D

All your mentioned lenses are full frame.

:bsmilie: I like the way you put it. DX lens on FX body, not much problem, with the exception of cropping away several megapixels on the wide angle end. Some DX UWA lenses can actually work on FX bodies without the need to crop much when you shoot using the longer focal lengths, with the exception of a little vignetting.
