Peter - thanks for the reply. In regards to the distortions I am seeing, I suppose at A3 it may not be visible. However when I blow my photos up to full size on the screen, around the corners I notice that the straight lines such as building begin to be curved. Is this what you call vignetting?

I suppose the only reason why I am even seeing it is because of the 550D's incredible resolution. On my old 6mgp there was no magnification to 5000 odd by 3500 or so. I was curious if there was a lens that is designed to cope with that level of detail.

And hoping like hell it isn't an L series (yikes! the $$$''s). Do Prime lenses behave better in this regard?

Jason, thanks for the tip RE 17-55 USM. Yes that is a faster lens.

thanks everyone for the discussion, I kind of wish I had come here sooner and learnt more before plunging down the mullah. I was seriously eyeing off the 7D Platinum pack.

Having said that, I just could not justify the extra $1200 or so (specially since this is my first DSLR).

Cheers
