Excerpt: Be careful when buying an Olympus teleconverter as they work only on a limited number of cameras and with a limited number of lenses. This teleconverter is for the old and larger bayonet mount lenses and will not work with the Pen series, EM-5, EM-1, and other cameras that have the Micro Four Thirds...
It's a darn site cheaper than a comparable telephoto lens and Olympus glass is some of the finest on the market

Summary: I'm using this Teleconverter with my Olympus E-5 and my Zuiko 50-200 F2.8-3.5 telephoto lens and it works superb. Gives my lens a 400mm reach at F7.0 that I would not have and it does not degrade the photo's to any real noticeable extent.
Summary: I had a 2x multiplier that I purchased for about half this price a couple of years ago and I hated it. It was terribly distorted and gave a fish-eye look to the photos. I read the reviews on this one and purchased it because everyone loved it. I'm not disappointed.
Excerpt: I have a Olympus Evolt 620 and use it mostly with a 70/300 lens. Wildlife....mainly birds at this point...and, wanted to get even closer...less cropping. This is working perfectly....did not add a great deal of weight as I handhold the camera.
Summary: I have wanted this lens for over 2 years but couldn't afford it. Got it and although I'm a novice, I can see the improvement in pictures - it is amazing. I can crop pictures with better clarity and printed on Red River photo paper - WOW.
Excerpt: I purchased the teleconverter for wildlife photography.I was pleasantly surprised when I found that I retained the autofocus and exposure function on my Olympus E30 with a 4.0, 300mm lenses. It does occasionally produce a little noise but I guess that is be expected.
Pros: Durable, Easily Interchangeable, Strong Construction
Summary: Got the EC-20 mainly for telemacro photo. Even if not specifically stated by Olympus, it works well with the 50mm F2.0 macro lens as well. I tested it with the 70-300mm tele lens, and the results are good. Besides the 2-stop that you lose anyway, no major drawback.
Summary: I purchased this product in hopes that it would help me get more distance on my pictures at High School Football games. I had read others reviews stating that the converter was not that good in low light but had hoped that the lights in the stadium might be enough.
Summary: I'm using this Teleconverter with my Olympus E-5 and my Zuiko SWD 50-200 F2.8-3.5 telephoto lens and it works superb. Gives my lens a 400mm reach at F8.0 that I would not have without the EC-20, and it does not degrade the photo's to any real noticeable extent.
