Canon t2i Edges Look Terrible
 

I'm assuming it's my fault but I'm not sure what I'm doing wrong. Any instance where a thin line is is in my shot, the line looks pixelated and flickers.

It's shaky, I know! Need to get some IS lenses or start dragging the tripod around.

Do a search on "Canon aliasing", "T2i aliasing", or "DSLR aliasing" and you'll get lots of hits.

DvSLRs do best when shooting people with a shallow depth of field. If you shoot things with straight lines with everything in sharp focus, you will get ratty edges.
