So... for the past few years with my XSi.. i was under the impression that full frame- under ALL circumstances- gave u better quality images... I was assuming that FF was always sharper, better color and better performance in low light, with wider latitude for post-editing.... But i have been told a few times now that it depends on the situation.., and that perhaps it is really almost always MORE about the quality of the LENS..... Yet i dont know ANY 'professional' who works with anything less than a FF... I am becoming increasingly serious about my photography- especially since i have an increasing amount of work that is coming my way, through word of mouth... I am interested more and moreso in fashion/food/travel/portrait and nude photography... I have about 4 lenses so far - 18-55 kit, a wide angle tamron, a 50mm/1.8 and a 200mm/2.0...i think a macro will be next, as well as a zoom portrait... Am i wrong in thinking that a FF would ALWAYS serve me better with those subject interests...? I am really probably goning to get a FF regardless... but just wanted yo see if there are really are any reasons NOT to, with my eventual photography interests as listed here... my site, if it helps http://stefographer.zenfolio.com/ Thanks so much all..u guys (and gals) give great help..
