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.
