Hi. I'm trying to decide on going full-frame (Nikon D700) vs keeping my old D80 and buying a wide-angle lens for those landscape/architectural photos, which I like to shoot. Wide-angle lens Much cheaper (spending <1000 EUR for the lens) Can keep my old D80 body (though I probably will buy a D300 if I go for this option) Can keep my Nikon 18-200 lens which I absolutely love as an all-purpose walk-around lens. I didn't find a full-frame equivalent for that lens and I doubt there will ever be one since a full-frame equivalent lens would be too heavy and bulky. May have to get rid of all the DX lenses I buy now and in the future if I decide to go full-frame at a later time. Full-frame Much more expensive (EUR 3000 - 4000 for a D700 and a good starters lens). No good replacement for my Nikon 18-200 DX VR lens. Full-frame lenses in general more heavy and bulky and more expensive. Future-proof. Anyone give me some good advice? Will the DX cameras disappear in a few years in favor of the full-frame cameras or will they continue to coexist? Thanks.
