Thanks for quick reply... I love my 28-135 IS USM... which attached to my A2E all the time. As you said, I will loose the wide angle.. I do have a 200mm L f/4 ( an old one, forgot the exact zoom range, because I hardly use it).

I like the 17-85 zoom range too, but was thinking that the 17-40 is an 'L' series... maybe the quality won't be noticeable?

Actually my budget is not that great.. since 20D has $100 and I have been waiting to get a DSLR since D30... (maybe this is a good time to get a new toy???... )..

I have been using my 'old' Powershot G1 for years... take good pictures.. but hate the shutter lag....

My newborn baby 'boy' will be coming in August... I would love to use this new 'toy' to do some good pix of him.

Thanks again.
Kevin
