Soft at f7 with the 50-200mm, Wednesday, 27 August 2008

I have been using Olympus 4/3 equipment since the advent of the E-1. I thought that the 2X teleconverter would be a nice addition to my lenses. Using my 50-200 mm zoom I was disappointed that the otherwise amazingly sharp lens became very soft wide open (f7) with the teleconverter. By upping to f11 the image sharpened and useable. Of course, I was hoping for a quick and dirty way to get a truly super-telephoto lens but it was not to be. i think that it was my expectation rather than the lens performance which was at fault here but none-the-less I thought it would be worthwhile to post this review to advise others that the combination of the 2x and the 50-200mm has some problems. Also, I was surprised to find that the lens was actually manufactured in China, not Japan. The build quality is excellent and for those who have lesser expectations this might be a very good choice. One needs a VERY fast lens with this piece of equipment. i have returned the teleconverter and will search for another purpose built option.

Fantastic piece of optics. I am a professional photographer and it's primary use will be to work with my Olympus 70-300mm zoom, creating the 35mm equivalent of 280-1200mm...WOW!!! Giving up 2 f-stops is no big deal when the trade off is such incredible magnification, short focal distance and cost savings compared to fixed 1200mm lens out on the market. Remember to check for lens compatibility before purchasing!

OK, let's get this out of the way -- the EC-20 isn't cheap. You can buy a nice lens for your E-system camera for less than this guy costs.

But once you start looking past the "kit" lens(es) you bought with your camera, you'll want to move up to Olympus' higher-grade optics. And if you ask me (although I'm quite aware you haven't), the EC-20 should be one of the first upgrades you look at.

Coupled with the 50mm f/2.0 macro lens, it's a boon to close work -- letting you get frame-filling images without having to be on top of your subject. For everything else, it can essentially double the number of lenses you own, presuming you plan ahead a Bit when you buy them. Buy the EC-20 as your first step up from your kit lens(es), and you'll save yourself money (and weight!) over the long haul.

And did I mention that images you take with it are tack sharp?

I just purchased Olympus Zuiko EC-20 2x Teleconverter. I have used it with the Zuiko 14-54mm zoom, the Zuiko 18-180mmm zoom and the Zuiko 70-300mm zoom on an Olympus E-330 with much success. I couldn't be more pleased. I'm accustom to Nikon film cameras with high dollar Nikon glass, but I am very pleased with Olympus digital products. I have already gotten some beautifully sharp, calander quality, wildlife pics @ 1200mm (35mm equiv) with the Zuiko 70-300mm four thirds digital zoom. Simply Amazing! I have paid Nikon much more for much less.

Excellent addition to my E-510. In fact I would almost consider it a must have. RFG

A 2X teleconverter requires a lot. Not only does it have to have good optics itself; it has to link well to the primary lens, supporting quick focus and aperture settings. It requires high end optics on the far end of the teleconverter, as well. The Zuiko 2X teleconverter easily meets these requirements.

Used with the Olympus E-3 and the Zuiko 300mm f2.8 lens over the course of two weeks in the field, it performed flawlessly. Autofocus, even on birds in flight, was quick and reliable. I've cropped photos taken with the teleconverter and my 300mm by as much as 50% and not been able to find any defects or flaws. The focus is crisp across the image. Because the Olympus System uses Four Thirds technology, with a much smaller sensor than most digital SLRs, the potential for problems is probably higher. I encountered none.

This is a fine piece of optics that does exactly what you ask of it. Highly recommended.
