I’ve had the Canon R5 for 18 months now and only recently began to find some dust spots. That is amazing, as I always had to clean the DSLR sensors every few weeks. The 1DX2 threw oil from the shutter and needed cleaning almost weekly. I assume the shutter protects the sensor better than the mirror did. But now it has a few more spots than I want, and they won’t blow off so it’s time to swab.
I saw something somewhere recently about an extra caution for cleaning a sensor with IBIS, but it was for something other than Canon – didn’t note what. I’m not sure why it wouldn’t apply, though. Canon gives the procedure for getting to the sensor for blowing off dust and won’t say anything beyond that except send it in for professional cleaning. But at over $60 a pop (last century’s prices) and over a week downtime, no way. I can do the same cleaning they can, but would appreciate the best information about it. I found some videos using Canon mirrorless bodies that do the same swabbing as everyone did with a DSLR, with no further steps with regard to an IBIS sensor, so maybe at least with Canon, it’s not important?
Here are the steps I found for that other mystery camera:
set IS to OFF (presumably IBIS?)
change shutter to ES so it won’t accidentally trip (what is different about ES?)
turn “shoot without lens” to OFF (should be default)
turn power saving mode OFF so camera will not power down in 2 min
I would think that going into cleaning mode would set whatever is necessary. I will test the 2 minute power down thing.
The Canon R5 manual does say if the battery is getting low it will beep to warn you before it shuts down and closes the shutter.
Is there anyone out there who cleans their own sensors in the mirrorless world? I’ve been cleaning my DSLR’s for 24 years with excellent results, and have a tutorial on my web site on the best way to check for dust spots.
What I didn’t say, and should have, is to check after swabbing, as it can sometimes take several tries and it may get worse before it gets better. I seriously doubt that any commercial cleaning operation would go to this much trouble after swabbing.
