Small suggestion about the review "The physical length of the lens remains constant regardless of the focus setting".
This statement is not quite accurate. The lens does actually extend, it's a helical focus drive that moves the whole
lens assembly forward. However, the movement is tiny, i.e. about 0.5mm.

Are you talking about the inner lens tube or the whole lens (including hood that is) ?
I didn't notice any extension of the overall physical length but maybe I'm wrong.
Thx
