| p.1 #10 · Push/Pull Zoom vs Rotating Zoom Ring |
I use two similarly weighted lenses, 100-400L and 70-200L f2.8 II.
I don't even think twice about it when using either the push-pull 100-400 or the twist 70-200. It quickly becomes natural.
The 100-400L works well as a push-pull, since if it were a twist zoom and it still extended the same amount, the balance would quickly get thrown off. With push-pull, this is not an issue as your hand moves with the balance point.
Since the 70-200 is an internal zoom lens, shifting balance is a moot point, so a twist zoom is no issue.
When you think about it, the lenses are exactly the way they are for very good reasons, almost like Canon has experience in lens designs
