I finally sold my non-IS 70-200 and updated to this amazing piece of glass. So far I am incredibly impressed with the image quality it produces on both my 5D2 and 5D3. I just have a few questions regarding the proper use of some of the switches:
- I have heard in the past that it is not good for a lens to switch from the image stabilization off when the camera is powered on. Does it matter if I switch image stabilization modes from 1 to 2 when the camera is powered up, or should I turn the camera off before I make the switch?
- Another thing I noticed is that there is a slight wiggle, or a bit of movement left and right, when the lens is attached securely to the camera body. Is this normal to expect this slight movement?
