I'm a student at academy of art, and am considering an SLR for portfolio development [imaging & new media], and use for photoshoots for a magazine I have. I've been checking out the nikon d80 and more recently the canon eos rebel t1i, which has been compared to the d90 because both the t1i and d90 have HD video capabilities [which is cool but not neccessary... but then again what really is?]. THEN there was talk about how the d80 was now obsolete because the d90 is out. I just want to know if the d80 has any major flaws. I'm considering buying one on craigslist for 590 [body+50mm f1.8 lens+batteries+8-16gb memory+manuals/cds, etc.] Can anyone give me any information/opinions on this subject? Also, if anyone knows how good the Nikon 50mm f1.8 lens is for close-up/close focus shots, or can explain what f1.8 even means, that would be helpful. Thanks!
