The Lens is very crisp and I have been able to take some very nice images with it. I do suggest using a Mono Pod with it for assistance. The drop in filter system makes it work easy. Using with the EM-1...it is very fast focusing and handles well.

Frozen Feather Images
I'm a nature photographer, primarily photographing birds. I need a lot of power, razor-sharp quality and good performance in low light. This lens delivers. It is without question the best lens I've owned.
It performs well with a 1.4 and 2.0 teleconverter, at the cost of one and two f-stops, respectively. I've lugged it (and it is a beast) from Barrow, Alaska to Antarctica. It's performed well in the steamy Amazon basin and at -40 F in mid-winter in the boreal forest.
I've owned the lens for more than five years. I've had exactly one problem with it, which Olympus fixed at its expense, AND gave me a loaner lens while mine was being repaired. I've fallen in it, cracking two ribs, without damage to the lens.
Solidly built, dependable and stupendous performance. My unqualified endorsement.

I rented this beauty for this year's Canadian Grand Prix in Montreal. This lens is simply amazing. build quality is almost tank like, although I was more careful with it than a newborn baby. The focus range selector is great and performs very well. The focus itself is responsive although it has a tendency to be a bit touchy. When coupled with my E-30 it produced stunning pictures. Pictures came out sharp with great detail and color, even when shooting handheld (yes I managed to last 3 days without a tripod/support). The drop in filters are amazing and are very easy to swap out. There are only two drawbacks to this lens: first and foremost the price, although I understand why it's still a lot of money, second is the weight this thing nearly broke my neck. It is a very hefty piece of kit. If you have the money to invest then it is definitely a must have, if you only shoot at 300mm on special occasions then it is a great rental and I would recommed it to anyone who is part of the Olympus family. Thank you Olympus for a piece of art. 9/10 (the price made you loose the perfect mark).
