(More customer reviews)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.
