I got a T1i 2 months ago and have taken 8000 shots. 50-75% were probably messing around with different settings, bracketing (WB, exposure), and other tests. It seems like a lot of work for the internal components. How many times can you flip the mirror until you wear it out? Any estimates out there? I know I'm not the only one to take this many pictures in 2 months....it may seem low to some....to others it may seem high. I'm just wondering how many shots a DSLR is good for and how much it costs to fix once you wear out an internal component. Thanks.
