When I made the move from Nikon to Sony, dust became an issue for me. I was not only moving from one brand to another but also from a DSLR to a mirrorless system. While my Nikons were not immune to sensor dust, it was never a big issue. I suspect that the mirror protected the sensor from stray particles. With the mirror gone1, dust seemed to be magically attracted to the sensor every time I swapped a lens.
I used to fight dust with a Rocket Blower. But recently, I also started carrying a small Nitecore BlowerBaby BB2 fan. It’s about the same size as the Rocket but can do a bit more. Actually, I like it so much that I think it’s the number one sensor fan in the world2.
