hello Sir, I am new to this forum and a newbie at photography. I have a question as I have an opportunity to purchase the Nikon 200-500 5.6 E lens at a good price and I have the Nikon D90. I see that there has been some talk about compatibility. My question is, is it just the Aperture that won't work as you stated? I just want to be sure but I am not to concerned as I plan on upgrading the body and figured I didn't want to loose out on this deal. thanks
