When shooting action sports with a vertical grip in vertical position, which IS mode should I generally be using?
When I shoot horizontal action sports, I normally use Mode 2. However, I don't believe the lens knows that I'm in vertical mode and that Mode 2 should be switched 90 degrees. Is that a correct assumption?
Equipment used: Canon EOS 40D, Canon 70-300 IS USM, Opteka Vertical/Battery Grip.
Thanks in advance!
