Product Description

Amazon.com Product Description

The Sigma APO Teleconverter 1.4x EX DG for Nikon 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

By	Paul Johnson "pfjbaldwin" (Baldwin, MD United States) - See all my reviews (REAL NAME)

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 Excellent add on, May 29, 2008

By	Philip Loria - See all my reviews (REAL NAME)

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.

4.0 out of 5 stars Works as designed, great little gadget, October 6, 2007

By	G. M. Wong (Sacramento, CA United States) - See all my reviews (REAL NAME)

I have both a Sigma 50-500 (aka Bigma) and a Sigma 100-300 f/4. Prior to getting the latter, I was able to use the Bigma with my Kenko Pro 300 1.4X TC DG on my Nikon D70. However, the Kenko refuses to work with the 100-300 so I have to buy this Sigma TC which works extremely well with the 100-300. However, unlike the Kenko, I cannot retract the Bigma all the way with the Sigma TC which is why I only give the Sigma TC 4 stars.

The 100-300 f/4 focuses as fast with or without the TC and I don't seem to lose image quality with the Sigma TC either. The EXIF info also correctly shows 420 mm was used. [...].
