Hi all. I've recently come into a little money and can upgrade from my 40D if I wish to. I started back into photography with a 40D about 15 months ago, and have been using a Sigma 10-20, and a Tamron 28-300 VC. I thought I would use a couple of decent zooms until I had a good idea of what primes to get, if indeed my skills would merit any more expense. Well I think I can justify moving upwards so I have a question or two. If invest in a 7D will I still get images as good I do with the 40D with the zooms? Or will I need better glass from the outset with this body? I would like to continue using the zooms as general use lenses, as I find them handy as "walkabouts", depending on my "focal length" mood. Ideally I would like to keep the 40D for using with the zooms, and get primes for the 7D as funds permit. Thanks in advance for any advice.

) and I think improved it. I'm very pleased with the lens and have had some cracking results with it
