I got this lens and an adapter for my Nikon 8800 for Christmas this year. You need the adapter - unfortunately, the adapter is so long that once the lens is assembled on your camera and you try to take a picture with the wide angle lens, you get a black halo effect on your image as it looks like you're taking the picture through a dark tunnel. I tried moving my zoom out a little to account for the long adapter, but you have to be careful not to zoom out too far or you get a lens error message after running into the wide angle lens. And by that time, you've lost your wide angle effect you were going for in the first place. Spend the extra $$ and go to an actual camera store to get a wide angle lens. I'll be going to Wolf Camera next week to see what I can salvage from this new lens. By the way, trying to return this lens is like working in the circus... Just how many hoops are you willing to jump through to get your money back??
