When I bought my Canon 5DM4, it came to me with a slipping top wheel. Mostly, this wasn’t that big a deal since it controlled my shutter speed in natural light – there is a lot of wiggle room in shutter speed, and I don’t usually have to fine tune shutter speed shot to shot. After 7 years of use though, it was pretty apparent that the slippage was worsening and needed taking care of. Even then, though, I was willing to live with it since getting it fixed seemed way too hard.
Things came to a head though when I decided I wanted to relearn some lighting techniques that involve going up a stop or down a stop on my settings, and which involved counting clicks. Counting clicks doesn’t work if your dial skips or slips, so it was time.
Thankfully, my friend had just sent in his Canon last year and said that the experience was really positive. He recommended that I call Canon, explain the problem, and see what their turnaround times were in this pandemic era. When I called, the Canon people were great. I’d registered my camera with Canon already, so they knew what they were looking at, and they printed me a shipping label and explained the process. Overall, it took about a week for them to receive my camera, get it checked out and repaired, then do a maintenance check to make sure all was well.
The whole thing cost over $400, which is pretty expensive, but the work was done by pros, the process was pretty seamless, and I got a functional, clean camera back within a week.
