Pros: Weight speed maneuverability

Cons: As always for these lenses the high price

Opinion: I have been using this lens for a few months, I had many doubts to replace my EF 500 f4 ISII that for many years has given me a lot of satisfaction. I spent an interlude of time using a canon EF 400 f4 DO II with which the spark did not go off. My only doubt for this lens were the missing 100 mm that these days always serve, but if I compare the weight and handling I am convinced immediately, I reduced the weight to a minimum using leofoto bracket (recovered from the previous lens) and folding lens coat hood by doing so you can afford to do wandering hunting even at my age. Autofocus speed certainly the fastest I've ever had, with 1.4 you don't notice any difference and with the 2x it's very fast. Quality: remarkable optical yield at 2.8 if I think that I can have an 800 mm f 5.6 using the 2x also considering the fact that the quality suffers, but I do not see all the difference that I have found in other optics. I will continue to use it in various conditions to see more strengths and weaknesses. I continue to trust mom Canon, but considering that parts of the body have already taken my kidneys I need. Surely the positive thing that the used is easily given away and this makes the difference because it sweetens the pill.
