I rarely use my Sigma fp so it's basically like new and nothing could have worn mechanically up to now.

But the dial on the back of the camera suddenly started to behave erratically. Instead of changing the value up it could randomly change it down, and vice versa.

I wonder if someone has met this problem, and maybe there is some way to fix it without sending the camera to repair.

I'm thinking about maybe injecting a small drop of 99.7% isopropyl alcohol under the wheel to clean it from the inside, could it be harmful?

This dial was a disappointment from the start. It is so flimsy and cheap and rotates too easily.

Just fast rotate it a few times it should clean oxidation or dirt
