I have the Canon EF 100-400mm f4.5-5.6L IS USM Lens that I nearly always use with the monopod...(it all gets a bit heavy after awhile!)...

The question, "Do ya think I should be turning the 'IS' off?"

My theory up til now is, that there is still movement as I track/pan/follow my subject (Birds) through the bush, unlike the camera/lens sitting motionless on a tripod...but, I nearly always photograph perched birds, so, I've come to a complete stop before clicking!

Obviously, now that this thought has crossed my mind, I'm going to switch it off for the next few days and see if I can notice any difference...
I guess in short..."has anyone else considered this or experimented as well, or am I just overthinking everything?"



Cheers -
