Yeah i'm talking about old nikon lens on modern nikon FX body, ignore my comments.
However, since you are into video, this is a good read for you:
"I recently took the plunge into DSLR cinematography by purchasing an $800 Canon T2i. If you scoff at the idea that video shot on a consumer grade Rebel can be taken serious by pros, I look forward to showing you some of the video I’ve been shooting. I’ll post a proper review of how this unpretentious game-changer is working for me in my documentary work soon. But today I want to talk about lenses."
It basically talks on use of adapters and whatnot.
Good Read, but I'll probably look into the adapters and new lenses in the future. I'm still not sure about having the adapters permanently stuck on the lens..
