I plan on getting a used body - probably 40D or 50D - and I notice some for sale already have replacement shutters. I have a few questions:
1) Is fitting a new shutter an easy job, or does it risk throwing some parameters out of alignment unless it's done very carefully?
2) Would you anticipate any differences between a Canon fitter and an independent person/lab?
3) If a camera already has a new shutter and we presume 50-100,000 actuations, are there any other parts of a body that are also at risk of wearing out?
Just wanting to know if high-mileage cameras should be avoided or if a new shutter is a simple matter and gives the camera another few years of good life.
Pros and cons?
