Product Description

Amazon.com Product Description

The Sigma 2.0x APO teleconverter lens features a high-performance optical design with five elements in three groups. It is optimized for use with longer telephoto and telezoom lenses, and is ideally suited for use with the 70-200mm f2.8 APO EX HSM zoom lens. This lens provides both normal exposure and autofocus function, while maintaining its high optical performance. Since it uses 10-pin electrical interfaces, there is no loss of autofocusing speed when these teleconverters are used with compatible HSM type lenses. This model is dedicated to Canon AF SLR cameras.

This lens uses two ELD (Extraordinary Low Dispersion) glasses and two SLD (Special Low Dispersion) glasses for utmost correction against chromatic aberrations.

4.0 out of 5 stars Nice tele converter., January 28, 2002

This review is from: Sigma 2.0x APO Tele Converter Lens for Canon SLR Cameras (Electronics)

I bought this teleconverter to supplement a 1.4x converter that I already owned. I wanted to try it out with my Canon 200mm 2.8 lens and compare the results to my 400mm 5.6 lens.

The converter is nice and compact, has a good quality feel to it, and seems to work very well. I shot one roll of film with it so far and was very happy with the results.

Remember that you lose 2 shutter stops when using this converter so it should only be used with a fast lens such as a 2.8 or 3.5 etc.

This review is from: Sigma 2.0x APO Tele Converter Lens for Canon SLR Cameras (Electronics)

I bought this teleconverter with a 70-300 sigma lenses and it did not mention anywhere (editorial reviews or specifications) that it is compatible with only a specific number of lenses. But the review for the nikon compatible teleconverter it does so. Make sure before you buy it that it will fit your lenses.
