I purchased this lens shortly before a trip to Hawaii. It is very large and requires its own carrying bag. It is heavy so a tripod is almost a must; I have occasionally used it freehand but more often with a tripod or monopod. It provides outstanding sharp photos at long distances; with the f2.8 stopping action is great (surfers; shore objects from a ship a mile or two off shore). I have used it at sporting events and have even used it for some astronomy work (great for the moon). It was perfect for several graduations. I generally use it with my E3 body, which makes the whole system very weather resistant; I have also used it with my older Evolt 500 body with equally impressive results.

It is an expensive lens but I have never regretted the investment in it; I've gotten more use from it than I expected when I purchased it.
