This lens has crystal clear optics.
I use it on my E-5 and I have to commend Olympus for creating such a fantastic four thirds prime lens.
I have taken thousands of photos with many lenses that I currently own and none have ever compared to the quality of this 150mm f 2.0 lens.
It works well for sporting events, wildlife photography, portrait photography, video photography, etc.
It's expensive but well worth the money. Unfortunately Olympus has stopped selling this lens at this time, but with a little luck they will eventually come to their senses or maybe some really nice ones can be found on the used market.

This lens is the first reason to buy the E-system. Top image quality, bright view finder, and still compact. The perfect walk around lens in an urban setting. It's effectively a 300mm, but it's still compact. The build-in image stabilization of the E-5 and the fast autofocus allows for sharp images with narrow depth of field at 1/100 sec shutter speed. Sharpness from edge to edge at all apertures.

Excellent lens. Very sharp. Brilliant contrast. Perfect Portrait lens.
