All ¨L¨ Lenses in One Package.

I was a little disappointed using it at high ISO... it doesn't look ¨too¨ sharp as I expected to be an L lens of this price tag, but besides that the picture quality is outstanding. For video it's a little difficult to handle and control the manual focus compared with other small lenses, but is not a big issue (while handheld).
The weight... well.. it's literally like a bazooka, but you will get used to it.
This lens worth every cent you pay. You have all the range covered with the outstanding ¨red ring¨ quality.
I will just add my super-wide angle 10-20 for some special shots.

Pros: Fast Auto-Focus, Superior Build Quality, Super-Sharp Images, it's an all-weather lens..
Cons: Semi-Sharp Images, Difficult To Manual Focus For Video Shooting.

Maybe the problem with high iso shots looking soft is more to do with the 7D than the lens as the 7D has the unfortunate reputation of a higher noise level. I have two 7Ds and found this to be the case. I sold my 100-400mm lens in facour of the 28-300mm and am very happy I did so. The photos are so much clearer and sharper but at twice the price I would expect no less. After the first hour of carrying the lens the weight is no longer an issue, but if you are coming to it from small kit lenses you will  notice a significant difference for a hile. For me however coming frorm the 100-400mm it wasnt that noticeable. I used the 18-200IS lense as my travel lens but this one has replaced it prettty much, so good is the zoom range..
