I have been contemplating buying a larger zoom lens (currently have 70-300) and have been looking at the Sigma 150-600. I like the Canon "L" lenses but one in that range is way out of my price range. Another alternative was to look into getting a crop sensor camera body to get a virtual extension to my current zoom. I found a 'bundle' on a police property auction site for a 7D body, 2 kit lenses, LED video light panel, backpack and a few other knickknacks. The camera looked in good shape so I made an offer figuring I would be outbid since it was somewhat low. Well, turns out, I wasn't outbid and my decision was made for me. I am now the proud owner of a Canon 7D body and other assorted items I don't need and will sell to recoup some of my money. The camera itself is almost blemish free and functionality checks out 100%. The shutter count is about 69k out of a 150k life, so that's OK. The battery(which is the same for my 5D2 body) still has a lot of life in it and my lens range is now extended to 480mm with my Canon 70-300 DO lens. I'm selling the 2 kit lenses to a coworker who is just getting into photography for cheap and will probably sell the LED light panel as well. I was surprised at the price on Amazon ($200). I got the entire package for 500 so I think I got a really good deal if I can recoup about half. So far, I like some of the features on the 7D. And, some of them are better than my 5D2 that I've been shooting with. I just need some better weather to go out and put it through its paces.
