I have a Rebel T2i. It has about 35,000 frames on the shutter. I think it is an awesome body for the price. A 5D Mk III is about a stop better in low light and a 1Dx is about 2 stops better. Both those bodies cost a lot more. If you are shooting demanding subjects, the more expensive bodies offer greater capabilities. Landscapes, cityscapes, portraits and wedding photography don’t strike me as usually needing more than a Rebel T2i/T3i/T4i.
