Brilliant! You forget it's there, until looking at the awesome results!

Summary: I was brought up on tele-converters being the poor relation, for those who couldn't afford prime lenses, but this one is superb! The optical quality is excellent and without access to expensive test equipment I can't say that it degrades the image at all, though of course it must.
Excerpt: I used this teleconverter with my Olympus 50-200 SWD telephoto lens, and got some fantastic results. The teleconverter is small and neat, and with it, my telephoto lens becomes a 70-280mm telephoto, with a loss of only 1 f-stop of light.
Pros: Durable, Easy to Use, Improves Function, Lightweight
Summary: I'm using this 1.4x tele converter with the Zuiko Digital 70-300mm lens to extend the range without as much light loss as the 2x tele converter would bring. I'm been using it for birding and flower close-ups where you're not allowed off the trail and it works quite well.
Summary: I got this to give my Zuiko 50-200mm zoom a bit more reach. With the EC14, the long end is 283mm (566mm effective focal length). I've used this combination on an Oly E-30 and an OM-D E-M1. When I have it mounted on the E-M1, I connect my sling at the lens' tripod collar.
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.
Summary: I do a lot of animal life pictures with my Olympus cameras,and needed some extra gain in distance for my Sigma Big Ma(50-500 mm) and this one gets me 708mm with almost no lossof quality!!(The EC20 works with some lenses but not too good with Big Ma!!
