I am having a bit of a time deciding. right now i have a Nikon coolpix 5400. i love this camera and i bought it at the time to see if i was more interested in photography (prosumer camera). i have started getting the hang of it (after 3 years....) and am starting to think about making my next step to dslr. i am thinking getting the nikon d50/70, or the Canon EOS 350D. first of all the nikon. does it have TIFF format? i have only found that it has 3 size JPEG and RAW. no TIFF? also lenses. i am confused as to lenses. i am reading dpreview lots but cant figure it out. i am mostly aimed at macro photography. especially small animals, bugs, microscope etc. are there any good sites i can look up to learn what lenses do what and why? preferably in a comprehensible way. maybe not the most important but the D50 uses SD cards. i have always used CF. how are these? in comparison to CF? Canon EOS 350D 2 more mega pixels. i know these are not the only thing to look at, but i do want to make prints. Would these extra 2 make a large difference in macro prints? prints may be up to 60cm. would i be compromising something else by going for this over the nikon? "Aperture range n/a" i don’t get it? what does it not show the range (dp review)? -/+2 EV, nikon is 5. 2 JPEG settings and RAW, no TIFF? I heard a few bad things about the sensors in the canon A series (A90 and such). If they were true, how are the censors now? All in all if wildlife/nature/biology photography was your focus, as well as travel. You did a LOT of macro work, which would you choose and what features made that decision? This will be a next year purchase to ensure i know as much as i can before buying. Perhaps then one of the better cameras will be comparable price? i do not want to go over $1000US for the body though, and will have little extra for lenses right away. Thank you so much for any feedback!!!
