Often you read reviews of self-proclaimed professionals and / or whiners
I would now like to measure this objective by normal standards and how it ideal for everyday use a man of simple delights in the Photography
Line pair counter and DxOMark worshipers please do not read :)
I myself pursuing it on a 7D next to a 70-200 2.8 (I) and a 100mm 2.8 L macro
Mainly I photograph dog sport if you want to call it so because that is. I need fast lenses
Personally, I'm excited and I can not fault it ala jiggling ill-fitting sun visor in my copy of which you read occasionally.
Also, I find that this objective one of the sharpest part of which I have ever use, the autofocus is quick and to the co-rotating focus ring can interfere with, I do not do it.
Every now and then is the weight faulted but seriously, who wants to have with 17-50mm throughout 2.8 simply has to take some glass in hand, at the 7D it feels the weight of absolutely ok.
My Conclusion:
Who is worried that not this lens is fast enough for sports -> It is fast enough
Who about lack of processing ensures -> It is very well made and worth every euro
Who is afraid of front / back focus -> Works with any lens happen please check times as it happens -> my fits perfectly
Who's afraid because of problem XY -> the people here is Amazon who is unhappy it may indeed simply return ..
All others I wish a lot of fun with it and Good Light
Addendum: The lens cap is really not very high but that is no reason for me here deduct a star, but a minor complaint
