Not comparable but still, here we go! A80 vs Xti + 50 1.8!! Here's what I've noticed. In order of decreasing importance. Xti doesn't have the flip screen thing! Oh man, I tried to take a shot of these aloe vera flowers in my backyard from the TOP but they're as tall as me, and I couldn't. That makes taking some shots impossible!! (advice? haha) 50 1.8's DOF is really shallow at f/1.8! So it seems like a lot of things are not sharp. I need to get used to this, as in what aperature to use in what circumstances. It seems that it's NOT (GRRRRRR) use a larger aperature for low lighting!! (GRRRR) (or am I wrong? ) I'm not sure if it's just me or what but the Xti seems to make things darker - like I'll need to +Ev to get what I like - and this in turn seems to make me use a higer ISO (although not much noise c.f. A80's [max] 400ISO) or makes me get camera shake. I like the bokeh haha, which isn't readily available on A80. Here's the aloe flower from the side. More to come later as I notice them heehee.
