TDP reviews the 85 f/1.4L IS USM

[Larsskv]

I read that as almost the entire optical system moving.

Indeed, looks like everything but the rear element is in the moving inner barrel. Thanks!

This helps me appreciate its accuracy and understand its lack of speed. I'm lucky with my copy--pinpoint even at 1.2.

+1. I am very satisfied with the accuracy of my 85L f1.2 as well. Paired with the 1DXII I have used it with success on running children as well.
