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. If you are hesitating to buy this teleconverter I can tell you that in my opinion it's well worth the money. It's a darn site cheaper than a comparable telephoto lens and Olympus glass is some of the finest on the market.
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. I get crisp, clear, undestorted photos. It's perfect for taking long distance photos of wildlife. You loose about 2 F-stops, but it's worth it.
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. Have uploaded and printed images from my first trial with 2x converter....very pleased.
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. No regrets and although it was used - it was in mint condition. Wish I knew more about specs for the real photographers out there - but to an untrained eye - it is a great buy.
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. Resolution will get a bit worse, but again, any lens you add brings additional distortion and quality loss.
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. It was obvious to me even before taking a picture that the image was darker just looking through the view finder. I would not recommend this product at all unless you are shooting on a perfect sunny day.
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. If you are hesitating to buy this teleconverter I can tell you that in my opinion it's well worth the money.
Summary: I love this product. Never had an issue with focus. With all the photo retouching software out there its no problem if you loose 1 f stop. Just make sure you use a mono pod or tripod and there is no problem.
