I've recently acquired a sigma 150-500. It has a 3 position stabilization switch - off, 1 & 2. 1 being full stabilization, and two being only in one axis.
I understand that having the stabilizer on when using a tripod is not a bad idea.
What have you folks found when using a monopod? Still plenty of movement to damp out there.
Welcome any and all thoughts or experiences.
