As I mentioned here, I’ve quite a stable of lens adapters. They all came in boxes that are too big for me to use in a storage cabinet, let alone a camera bag. They’ve been sitting in a pile in a Sterilite bin.
When I change a lens on a digital camera, I have a procedure that’s calculated to allow the minimum amount of dust to settle on the back of the lens or the inside of the camera, because I’m worried that said dust will make a semi-permanent home on the sensor. I loosen the back lens cap on the lens that’s going on the camera, and put that lens filter ring down on a table. I take the lens that’s being benched off the camera, and, holding the camera in one hand with the face pointing down, set it on the table and move the back lens cap from one lens to the other. Then I mount the new lens, set the camera down, and tighten the back lens cap on the old lens. It’s worked well for me.
Now, in the brave new world of adapters, I’m just as likely to take an adapter out of the camera bag and mount it to the lens. But what’s been keeping dust out of the adapter?
Nothing.
Realizing the stupidity of my ways, I’ve ordered a bunch of body caps and back lens caps, so each and every adapter can have its insides protected from demon dust when it’s not in use.
If you haven’t already, you might think about doing the same.
Like! I even go another step when I’m changing lenses at home. I go to place in the house that is rarely active with people. The dust in the air is greatly reduced. I always hold the camera clamped between my knees the free hand dismounts the lens and the other hand holds the lens to mount. The camera spends about 3 seconds exposed without a lens.
