I've had the 5D Mark III for about 6 months and have shot over 11000 pictures with it so far. It is a great camera for practically anything and is great in the lower-light environments that I shoot in, coupled with appropriate lenses, of course. I highly recommend it.
Lenses: (all Canon except one Sigma, noted): 70-200mm f/2.8L (non IS version), 200mm f/2.8L, 135mm f/2L, Sigma 85mm f/1.4, 50mm f/1.4, 28mm f/1.8. Note that my higher quality lenses are 85mm and longer since that's what I shoot mostly. The 50 and 28 are not "L" but are fine for when I need them not so frequently.
