EC - 20 Teleconverter

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. It's a darn site cheaper than a comparable telephoto lens and Olympus glass is some of the finest on the market.

Great Lenz

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.

It is very good product !

This product exceeded my expectations. It is very well built and works well with all Zuiko lenses I have. (50mm, 12-60mm, 50-200mm 70-300mm).
In certain low light conditions, naturally, auto focus is problematic, but also depends on the equipment used. It works perfectly with fixed aperture lenses, placing the camera in the form of priority in the opening, as the 500mm mirror lens I have. Perhaps it is expensive but gave a new spin on how to use my lenses. The new depth of field that allows me with my old lenses, it is very interesting.

Affordable Way to Zoom

I've had this converter for two years now and have found it very useful for zoo and wildlife photography.

This trick to this teleconverter is that you need bright light because of the loss of stops. I use it with my 50-200mm and find shots in bright light to be crisp and sharp even handheld. However, when the light is not good the shots can be soft. This is why I did not give it 5 stars. Overall, it's a great deal for long range photography.

Problem with AF

Whatever the lense used, AF not working properly. Require focusing manually...

Always out of focus

No matter what lens I use I can not get a in focus shot at all.
Using tripod make no difference
