one of the reasons why "the crop factor" was ever introduced into slr's is this: lenses naturally have lower image quality on the edges. no matter what kind of lenses you have, even the L's, this will always be true. with aps-c cameras (like your 40d, which is probably one of the best cameras around for its class to-date), the image is cropped such that you will get the image that is in the middle area of the lenses - where quality is at its peak. secondly, a pseudo-zoom factor is naturally in place due to the crop, as mentioned by @smc. for me, this is a good thing. heck, i know a lot of full frame photographers who end up adding hours and hours on their workflow due to cropping alone. might as well nip it in the bud.

sure, who wouldn't i kill for a mark3, but i'd rather go for a 40d with a stockroom's worth of L lenses. i don't know if this will help, but here's my medium term daydream. just play along with me - dreaming doesn't cost a thing.

- a brand new canon 40d body
- at least 3 batteries and the wifi grip
- at least 2 580EX II's, remote triggers
- a bigger apartment where i can have a studio
- umbrellas, light stands, wall outlets
- a maxxed out macbook pro and a maxxed out mac pro

and then the lenses
- EF 85mm f/1.2L II USM (hey, what can i say... this is probably the best there is for portraits. the 85mm 1.8 is nice, but let's go crazy)
- EF 16-35mm f/2.8L II USM (the 10-22 is nice, but it's not L, and useless if, in case i win the lottery, decide to upgrade to full frame)
- EF 24-70mm f/2.8L USM (rumors of a mark2 for this lens is going around, but no one can subtantiate. besides, it's almost perfect as it is)
-EF 70-200mm f/2.8L IS USM ('nuf said. oh, and i might want to get a Extender EF 1.4x II for this. the EF 28-300mm f/3.5-5.6L IS USM would be a good alternative, but i'd rather have the 70-200 with the extender)
