thanks guys! actually when you think about the price of thef2.8 IS mark II you can actually buy 2-3 lenses with that amount. in regards with the need of the f2.8, personally i think i don't really need it with what i do anyway but its nice if i could have it handy as i seeboth lenses are very good build quality & image quality wise. again, i think it goes down to personalpreference. thanks!
