[robbert100]

I had the 70-300 4.0/5.6L IS for a few days but wasn't impressed so I send it back.

Looking at the price (€1540,-- incl. tripod ring) I expected more from this lens. It's not a replacement for my 100-400 4.5/5.6L IS or 70-200 4.0L IS



The good things:



- very fast AF

- 4 stop IS is real

- compact

- scratch proof hood

- build like a tank



The bad things:



- to expensive (relative)

- optically less than my 70-200L IS

- optically about the same, maybe a little better but not much than my 100-400 4.5/5.6L IS

- no tripod ring standard, tripod ring feels gritty when rotating the lens, in no way comparable with the rings like the one on the 100-400 or 180-3.5L macro

- bad ergonomics due to position of the zoom and focus rings.



ps1: Lens was tested on a 5DmkII and 7D
