Summary: I bought this Teleconverter to shoot nature shots at Florida's wetlands using my Zuiko 50-200 SWD lens and my Zuiko 70-300 lens. The Teleconverter focuses super fast with the 50-200 SWD lens, and it focuses just fine with the 70-300 lens. The quality of the shots are not degraded in any noticeable way when using the Teleconverter in moderate to bright light conditions. I would definitely recommend this product to any one needing a little more reach.
Summary: I got that high grade teleconverter to use it with my 70-300mm zoom lens, I'm more than happy with the results. At 420mm, equivalent to 840mm in 35mm cameras, I still get sharp and crispy pictures even in macro mode. I strongly recommend it as a sure value for all serious photgraphers.
Summary: I purchased the EC-14 early this year after acquiring seventeen of the Zuiko lenses for the four thirds system. I have used this lens with the 18-180, 70-300, 50-200, 35-100 and 150 millimeter lenses and have been very pleased with the results. You will loose a stop of light, but when dealing with lenses as bright as f/2, that is a small price to pay to get closer to your subject.
Summary: Picked this teleconverter up for a trip to Tanzania to extend the reach of the 50-200 SWD telephoto lens. The added reach made a big difference for birds and distant animals. No visible loss of IQ. Great addition for a great lens.
Fabulous Teleconverter That Punches Well Above It's Weight.
10 January 2013
Summary: This incredibly well engineered little piece of kit punches well above it's weight. The 1.4x magnification may not sound like much, but on long focal length lenses the effect can be more significant than you might imagine. On a 70-300mm zoom for example, it extends the maximum zoom range to an effective 420mm which when taking the 2x crop factor of 4/3 format into account, is equivalent to an 840mm zoom !!
