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. Quality of photos, under E-3 excellent, under EM1 beyond outstanding. Be sure to shoot RAW/LSF -- don't use just LF, which is set by factory. Go into menus to access the LSF.
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. It really is like having a series of high quality primes with the control of your framing- very important to me. I expected to operate strictly in manual, but the systems worked well together.
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
31 May 2012
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. You usually need to get into the tele range for that sort of thing.
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. However I can only give it three stars because in lower-light conditions with the FL-50R flash attached it struggles to find focus and usually fails to do so. I have had to set it to manual. My discontinued 14-54 kit lens performs better in this regard.
Olympus f2 14-35mm on the E-5 is like giving a Ferrari paint job to a Mustang

Summary: I tested the Olympus f2 14-35mm lens doing some night shots and architectural photography. The Olympus f2 14-35mm lens is not intended for this application; however, this would allow me to see where the lens shines and fails. These are my preliminary observations: At F2, Olympus f2 14-35mm, when focused to infinity provides great DOF. I find it remarkable how much light I was able to capture to get fast exposures. I was photographing moving floodlight beams in the sky.
Excerpt: I'm using this on an AF100 and the image quality is excellent. It's an expensive lens but with a constant f2.0 aperture, it's like having 22 high quality primes in one lens. There are a few gotchas when using this on an AF100 but they're relatively easy to deal with. My lens had a dust particle inside the lens element (which did not affect the video) but I still exchanged it and the exchange process was painless, with BH paying the shipping.
Summary: It is absolutely perfect. I love the lens. Yes it is big, both in size and performance. I'm glad I have it and would do it again in a heart beat. Build quality and picture quality are just what I wanted and expected.
