I love my 24-105, and it continues to be my most used lens. You can find them at a slight discount as many were sold as "kit" lenses with the 5d and 5dII. I also bought a 70-200 2.8IS this spring and it is remarkable, but not necessarily what I'd recommend for "building" photos, as you'd need some distance. As you mentioned, the 10-22 is fantastic. I have borrowed a copy my bro-in-law owns and have taken many of my favorite shots with that lens. For me, the 10-22 is next on my list, and would just about complete all my needs. (OK, the next gen 100-400 would quickly jump onto my list once that comes out, just don't tell the "minister of finance" if you know what I mean.)


I HAD a 40d, but sold it to a friend this week, and have a 7d on order. I wanted the micro focus adjustment, improved AF, but could live without the video -- oh well. Now I just wish it would show up, as the leaves in NH are getting very pretty ;-)
