Amazon.com Product Description

The Sigma APO Teleconverter 1.4x EX DG for Canon Digital SLR Cameras is a dedicated APO teleconverter that can be mounted between select lenses and the camera body to increase the focal length by the power of 1.4. The multi-layer coating reduces flare and ghosting, which is a common problem with digital cameras. The lens also offers maximum magnification without any variation in the minimum focusing distance. Compact and lightweight, this teleconverter can convert your lenses into longer focal-length lenses, so you don't have to do a lot of unnecessary footwork. A case for the lens is included.

5.0 out of 5 stars Great match-up with the Sigma 70-200, f2.8 that gives you a 100-300, f4 zoom, July 14, 2007

Optically outstanding when combined with the Sigma 70-200 f2.8 EX DG. This new Sigma EX DG lens and converter is super sharp and great color that stacks up to the famed Canon L series at about 60% of the cost. I see incredible clarity at 800% magnification doing touch ups in Photoshop.

I've used both and wouldn't hesitate a second buying the Sigma DG series again.

Advanced amateur who loves Canon.

5.0 out of 5 stars Great alternative to extend the reach of your Sigma telephoto lens, November 2, 2009

This review is from: Sigma APO Teleconverter 1.4x EX DG for Nikon Mount Lenses (Electronics)

I get the Sigma Teleconverter 1.4X especially for outdor sport games. I have Nikon D700 & D90 and Sigma 70-200mm f/2.8 HSM. I feel that 70-200mm f/2.8 is too short on D700 (full frame) and D90 (1.5x crop), therefore i get this teleconverter. It is a good alternative because it is much cheaper than buying 300mm f/2.8 or 100-300mm f4 lens.
Build quality

Build quality is the same as typical Sigma EX (professional line lens) and very well match with Sigma 70-200mm f/2.8 HSM.

COMPATIBILITY

Sigma teleconverter 1.4 only works with Sigma lenses. There are about a dozen compatible lens, but only a few retain auto focus function. There are: Sigma 180mm macro f/3.5 EX HSM, Sigma 300mm f/2.8 EX HSM, and Sigma 70-200mm f/2.8 EX HSM.

AUTO FOCUS PERFORMANCE

I don't feel any difference in auto focus performance, so it remain excellent.

IMAGE QUALITY

It loses a bit of contrast and sharpness, but generally still very good. Check out sample images from my web blog. You can get the address from my Amazon profile.

CONCLUSION

Sigma teleconverter 1.4x is a great affordable alternative for Sigma telephoto lens' user, especially for those who need extra reach. It does not sacrifice auto focus performance and only degrade a little bit of image quality. But remember that the maximum aperture will be smaller by one stop. So it might not be very good alternative if you shooting in low light like night sports.

For the past year I have used mine on a regular basis with my Sigma 150 macro lens. This creates a 210 F4 macro that is amazing. It is not possible to tell, by looking at the pictures, which were taken with or without this TC. Buying this gives you a second lens of equal quality for a little bit of money.
