Yes, this is, sadly, Yet Another "What Lens Should I Get?" Thread (YAWLSIGT?) Long story short: Was gifted a 20D. Having fun with it. Found myself wishing for Certain Features. Found I could get most of what I wanted in a 40D, economically. Have one On The Way from Adorama. My wife plans to take possession of the 20D. (She's had a hard time prying it out of my hands.) Currently have an EF-S 17-85mm f/4-5.6 IS USM and EF 100-300mm USM. A friend is gifting me an EF 70-300mm f/4.5-5.6 DO IS USM for my birthday. We'll need another general-purpose/walking-around lens. Reading the various reviews of lenses my impulse would be to go for the Canon Zoom Lens EF-S 18-135mm f/3.5-5.6 IS USM. The only thing I can find not to like about that lens is the focus-by-wire, which I expect might be annoying. Recommendations on anything else we should consider? (Then comes the... *cough*... discussion over which lens goes on which camera body... .) TIA!
