Lovely pics ( though the lion eating does look macabre

)

Decent glass too....IS rocks
You will love the 30D.. more and more as you get to "know it" .
The ease with which you can access WB, ISO, AV comp, metering and drive mode , shutter speed and aperture, as well as speed of operation is nothing short of amazing. Shutter lag simply doesnt exist . Auto focus with the USM lenses is very fast and accurate and the 5fps is always a joy to have even if you dont use it often. Battery life is good too
You will get some duff shots but that will invariably be down to you

.
As time goes on the vast majority should be sharply focused and well exposed, the subject and framing will then then be ..once again down to you
