I still strongly recommend an autofocus capable body, such as the D70, D80, D200, D300, D700, or D1/2/3 series. Some excellent lenses you won’t be able to buy, or will have to pay for the AF-s version are the 50/1.8, 80-200/2.8 (USD$900 more for the AF-s), 17-35/2.8 (USD$700 more). Used? Most used lenses are NOT AF-s, so the majority of the used lens market will be useless for you.
Ok, and the D3000 and D60 havn’t isn’t compatible. Thats a very good point. do you know if the Canon EOS450D (rebelXTI) is compatible? [/quote]
…no, Canon lenses and Nikon lenses aren’t compatible without an adaptor. As i understand it, full frame lenses do fit on crop sensor camera’s but not the other way round. FF lenses are expensive though, so for you that won’t be an option. Third party manufacturers make lensen for either brand, are cheaper and offer similar quality, so check that out…
