If you turn off the feature that crops the image when you use a DX lens, you can get some funky vignettes.
Now, I know you could achieve this with a bit of cardboard, but it's not that much fun.
I shot this with the D700 from the back of a bus, with the 18-70 DX lens. I shot it in JPG and it was set to B&W, so no post-processing done besides sticking the logo on it.
I never use the crop feature though, because you lose like half the resolution if you do, so just don't buy a D700 with the 18-200 lens, like some rich stupid people I have met.
This is a quite pointless post, but I think the photo is interesting.
Anyways, here is a post on the DX FX subject. I have to update the table though, because it's missing some stuff from the very wide angle, but it's still useful IMO.
Have fun, kids!
