I had an opportunity to borrow a monopod on sunday to attach to my new sigma, and immediately reached for the switch to disable the optical stabilization of the lens.
Then while I was trying to photograph birds on the island in the lake at Forest Lake, I noticed there was still movement.
But it got me thinking.
I know that when you place a camera on a tripod, that it is always a good idea to disable optical stabilization, as the 3 legs provide a "very stable" base of operations
BUT
when a camera is on a monopod, the monopod can only provide stabilization in the vertical plain, and horizontal movement is still a real possibility.
so, how is the "rule" of "turn off image stabilization when using a tripod" affected if you are using a monopod?
