Not knowing what a "Global Shutter" is - what would the implications of this be if (hypothetically), it was launched on the (to be named) 7D update? Is there any benefit to the stills photography world or is it purely a video thing?
If 24-70mm f4 IS is parfocal - I would consider that. If it's not - you can not zoom on target and maintain focus.
The 24-105L is parfocal, the 24-70/4L IS is not.
Are you sure about this ? I always thought the 24-105 wasn't parfocal. After reading your post I tried it specifically to test this.
When focusing at 105mm and then zooming out it does seem to hold focus, but this may be the result of DoF on a f4 lens. However when focusing at 24, then zooming in it seems to loose focus.
