Ah, yeah if you're after a 2.8 then yes, big money. Want to get myself a 50mm lens with a large aperture for doing some portrait stuff etc, and the difference in price between the f1.8 and the f1.4 is daft.
Still, quite happy with my 300D, got it off someone who has to have the latest model, so every time a new one comes out, his current one goes up for sale
Might at some point upgrade to one of the more expensive models, if I ever take any photos to justify it that is! Think I'll stick with Canon though, that way any lenses I get now will still be useful to me.
