Yeah, I've had mine since January, it didn't come with any dust inside that I could see, but now I have a few small flecks in there.
It's not something I'm worried about, I did know about it ahead of time also. I'm sure it hasn't affected any of my shots.
I also have experienced the VF jumping sometimes when the IS kicks in. I guess it happens more in AI Servo mode. Hasn't bugged me at all, though.
R6 II --- RF 14-35mm f/4L IS --- RF 24-105mm f/4L IS --- RF 100-400mm F5.6-8 IS
70D --- EF-S 10-22mm f/3.5-4.5 --- EF-S 17-55mm f/2.8 IS --- EF 70-200mm f/4L IS --- EF 85mm f/1.8
On at least one instance, evaluating a newly-arrived rental up in our "studio", with AI Servo active, I had continued issues. I was focusing on a dark gray, opaque window covering. It had folds in it, and was lit by a nearby ceiling fan/light, so it had contrast to work with. However, focus (on a 40D) didn't want to lock in, and IS was jerking left/right in conjunction with focus hunting in/out. LensRentals replaced the lens lickety-split.
We're a Canon/Profoto family: five cameras, sixteen lenses, fifteen Profoto lights, too many modifiers.
