I looked through the past posts, but couldn't find this exact issue. I am looking into getting my first DSLR. I am assuming I will buy Nikon since I have 4 nikon lenses already - 24/f2.8, 50mm/f2, 105mm/f2.5, and a 200mm. However, they are all AI, so no metering if I got the d90. While I only shoot for a hobby (and probably only ever will), this still seems like a major negative. Is it? Is it worth it to spend the extra on the d300 to have the metering?
