Since December 2007, when I bought my first DSLR, I've been shooting with a Canon 40D and loving it (thanks, MRailing, for the recommendation!). I bought the 40D from Best Buy on a super duper special that included a 28-135 mm lens and a 70-300mm lens. In the past year and a quarter, I've accumulated the following lenses to go with my 40D:

• Canon 10-22mm f/3.4-4.5 USM
• Canon 100mm macro f/2.8 USM
• Canon 50mm f/1.8 (a.k.a. the "nifty fifty")
• Canon 17-55 f/2.8 IS/USM (I highly recommend this lens; it has become my primary lens, especially indoors)
• Canon 70-200mm f/2.8 IS/USM (a.k.a., "Big Bertha")
• Canon 24-105 mm f/4 IS/USM
• Tamron 28-300mm f/3.5-6.3 VC/AF (a very nice, walk-around lens when you don't want to carry more than one lens).

I also picked up the 1.4X and the 2X tele-extenders to go with the 70-200 and a 430EX Speedlight (though I wish I had gone with the 500 series).

As a result of my purchase of the Tamron 28-300mm , I no longer carry the Canon 28-135 or the Canon 70-300, I only wish Canon would come out with a 24-70mm f/2.8 with IS.
