Summary: This is a very expensive lens but it produces superb pictures. Highly recommended for landscape, interiors, and architectural photography. It is a fantastic lens in virtually every respect. Thanks to in-camera JPEG correction, distortions are kept to a bare minimum, which is why it is so effective for architectural photographers. Sharpness is fantastic across the frame. It is very well made.
Awesome! Be inspired by what you can do with this wide-angle lens!

Summary: I have had some amazing results using this wide-angle lens! I used it in Lisbon in the narrow streets and in cathedrals and achieved breathtaking shots that were impossible with my standard lenses. The shots were clear without distortion edge-to-edge. I am so inspired by the results.
Outstanding lens, small size, excellent super wide lens.

Summary: I purchased this lens for my Olympus E-P3 and for the upcoming E-M1. This is a super lens, sharp and well made. While it does take a little getting used to it can produce outstanding images obtainable with little else. One must be mindful of the bulging lens element in front not to bang it into something so I try to keep the cap on the front when I am walking about. I have used this lens at festivals, interiors, large groups, fine art and landscapes.
Summary: expensive, but if you love wide angle lens, this is the one to buy. One of the sharpest lens in M4/3 lens line up. Built quality is rigid and excellent compared to its rival, olympus 9-18mm. Is compact and internal zoom. Very versatile lens, photo and video due to fixed F4.
