For several reason's Im thinking of switching to Canon mainly for the optics and sharpness, among other things... Right now I have an Olympus Evolt-520 and like it but want to move "up" as it looks like Im getting back into photography again. Through help here I've started using off camera flash via some wireless triggers found on Ebay. I've started experimenting and the results show promise. I do a lot of outside glamour. I had my eye on a good deal for a Canon Digital Rebel XSi but then opened an issue of POP-Photography to read about the XSi: "Not So HOT: Still no built-in wireless flash control". So I cant use the wireless flashes system with the Canon XSi? (I have a Olympus FL-36 Flash and Im looking at the Canon Speedlite 430EX. The triggers work w/my FL-36 on M.) Opinions?
