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 work with both the newer MFT 12-40mm f2.8 PRO and this lens. This is still my go to lens for my important work. For the client, the smaller E-M1 looks much bigger than it really is once you throw in the 14-35 and the HLD-7.
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.
Summary: I have owned this lens for 6 months or so and use it professionally in a portrait studio with an E-5. I just cannot say anything bad about it. While it is somewhat large, it is an f2 lens with outstanding sharpness, contrast and color.
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.
