Extend the reach of your telephoto lens with this APO Teleconverter 1.4x EX DG from Sigma for Nikon F-mount cameras and lenses. This model will increase the focal length by about 40% while only losing 1 stop of light in the process. It also retains communication between the lens and camera, allowing users to use automatic metering and autofocus. Additionally, this teleconverter has a multi-layer coating that reduces flare and ghosting for sharp, clear imagery.

For compatibility please see this chart from Sigma which outlines which lenses can be used and the various functions possible with each.

    APO Teleconverter 1.4x EX DG for Nikon F is rated 4.2 out of 5 by 37.
    Rated 4 out of 5 by from Good accessory, but beware manual focus Very handy accessory for my Sigma 150-500mm making it up to about 750mm. Wow! A little soft but very very adequate. Easy to carry. Cuts an f/stop off, as expected, but more workable than the 2 f/stops we lose with the 2X teleconverter. But beware, I was unaware that it does not support autofocus on most lenses. So be sure to check the list of lenses supported before you buy. Thus, worthless for catching birds on the fly, and fast moving sports -- a big draw back. I follow the company's recommendation of putting telecoverter on the lens first, then the two onto the camera. Don't know why they say that, but I am afraid to test it.

    Rated 3 out of 5 by from Sharp but not great AF with Tamron 70-200 I bought this teleconverter to use with the Tamron 70-200mm f/2.8 Di VC USD on a Nikon D810. The image quality is great (the Tamron 70-200mm f/2.8 Di VC USD is a very good lens - almost as good as the Nikon 70-200 f2.8 VR II), but the autofocus stutters a bit, and is certainly not good enough for sports photography. It *may* work better on a Sigma lens, but I wouldn't know. The reason I got this Sigma 1.4 TC instead of the Tamron 1.4 TC is that the Tamron will NOT AUTOFOCUS AT ALL with their own Tamron 70-200mm f/2.8 Di VC USD lens. You gotta wonder how the Tamron 1.4 TC even made it out of the testing lab and into stores... but that's another story.

    Rated 4 out of 5 by from Using for about 6 weeks I bought this converter to go with my Sigma 70 - 200 f/2.8. I wanted a longer focal length while still being hand-held. The results are excellent. The autofocus works well and the images are sharp. I then added it to my Sigma 150 - 500 lens. The autofocus was lost, but I expected that. With manual focus, I shot multiple images to try to tune in to the subject. At 700mm, results are, dare I say, fuzzy'. But, with less than maximum focal length, some images were good (will still need some post-processing sharpening, but may make an acceptable 11 x 14). Bottom it for the 200 mm zoom.

    Rated 2 out of 5 by from Nice sharpness, poor construction At first, I was in heaven with this converter. I used it with teh Sigma 100-300, F4 lens and boy, did it work great! But then, after 3 months, the converter started to come apart. And now, it is unuseable.

    Rated 5 out of 5 by from very good product The Teleconverter is small light weight and doubles the usefulness of your lens. I am using this in conjunction with a Sigma 120-300 f2.8 and Nikon D7000. Results are very good, nice sharp images at F5.6 and still very good at F4. Have tried with my Nikkor 70-300 VR but results a bit soft, all functionality of the lens in maintained with both lenses. When using a heavy lens I would not recommend picking up by camera body as this will put a lot of strain on the converter, the 120-300 Sigma weighs(3kg) and would destroy this and your camera mount anyway, Holding by lens and body will see a longer life. All in all very happy with ... purchase, be sure to check compatibility chart before purchasing .

    Rated 4 out of 5 by from Good Choice for Modest Budgets the SIGMA 1.4 teleconverter is used on the SIGMA 120-400mm telefoto lens mounted on a Nikon D200 using a Manfroto tripod and Really Righ Stuff Ballhead. This combimation of equipment is used when photographing wildlife, primarily wetland birds. The teleconverter has worked flawlessly. A potential user must keep in mind that a lens with less than a f/4 maximum opening will have to be manually focused. Not a good choice if you plan on handholdimg a lens this large and manually focusing. This lens/teleconverter is a good combination for photographers on a modest budget

    Rated 4 out of 5 by from Useful Accessory I purchased this to expand the utility of my Sigma 70-200mm f/2.8 lens. While the sharpness does go a bit soft, the overall effect of increasing my lens to 100-280mm while decreasing the speed to only f/4.0 seems really useful.

    Rated 5 out of 5 by from RELIABLE PIECE OF EQUIPMENT Always wanted to buy this tele-converter and as soon that I acquired the Sigma 70-200 f2.8 II, I bough it. Works great with My Nikon D300 for birds on a fly and landscapes.
