Hi Mt Spokane.
When you say high shutter speeds, are you referring to high frames per second, or 1/8000th sec shutter speed. I thought the increased wear of 1/8000th was a myth as the shutter blades travel at the same speed for a 1 second exposure as they do for 1/8000th sec exposure, just the delay between the first and second shutter changes.
I can see where 10 or 14 FPS could be more wearing than 5 or 6 FPS.
Cheers, Graham.

The shutter life is a average expectation. It can vary widely, temperature is a big killer, so one exposed to high temperatures is undergoing a lot of stress. Hish shutter speeds also is tougher on a camera. Bumps and knocks can also affect the shutter.
All of these things plus more impact the life, so its impossible to set a actual number.
There is always infant mortality due to defective parts or assembly, if it fails right away, the warranty usually covers it as long as it has low actuation's.
