Summary: When you — for comparison to full frame systems — multiply the crop factor of 2 (for four thirds) with the focal length of this lens you also must not forget to multiply the aperture number (F-stop) too.
Summary: I own several lens for my OMD-1 and this one is by far my favorite one, I also own the 35 - 100 and thats also a great lens but this one is used for more situations, thanks to the quality of the lens and because its a 2.0.
Excerpt: I have been using this 14-35 F2 lens for 4+ years on my old E-3 with excellent results. I was about to give up on it until the OMD EM1 entered the picture. Results have been nothing short of outstanding. Inside focusing under dim lighting, fast; under E-3, struggles.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Five primes in one and great interchangeability on other systems!

Summary: A was worried about a legacy lens costing this much and putting it on my om-d being worth the price. YES it was and so much more. This series of zooms is simply unparalleled at 2.0 through these ranges. And the result is an incredible boost to your images.
Summary: Excellent for portrait taking. Heavy piece of glass. You feel the quality of glass your holding when it comes to Olympus lenses. Along with my E-5 or my micro four thirds OMD EM5 this glass is the best for it.
Olympus 14-35mm f/2 ED SWD Zuiko Digital review by jnolan

Summary: You might have noticed that this lens costs a lot. That's okay, though, because it's absolutely fantastic. First off, though, it's worth mentioning that this lens is huge. It's heavy and it's big. I find that it feels good on my E-5, but on my E-420 it feels like I'm attaching my body to the lens.
Pros: Image quality, Speed, Weather sealing, Build quality, Pride
Excerpt: For the price of this lens I would expect it to outperform the lower-priced lenses in the Olympus/Zuiko line in all regards. The image quality and out of focus quality is very pleasing as other reviewers have enthused.
