    Sigma 876306 reviews

    APO Teleconverter 2x EX DG for Nikon F is rated 4.3 out of 5 by 56.
    Rated 5 out of 5 by from Just what I needed I bought this teleconverter to use with my Sigma 50-150mm f2.8 lens. On my cropped sensor (asp-c) camera, I seldom need a lens longer than 150mm (225mm full-frame equivalent), so I could not justify buying a longer lens. The teleconverter brings my lens up to 100-300mm (150-450mm full-frame equivalent), which is perfect for my occasional need for a longer lens. The maximum aperture drops from 2.8 to 5.6, which is something I can live with. Autofocus works normally in bright light, perhaps a bit slower in low light. If you are a pixel peeper, image sharpness may not be quite as good as using the lens alone, but I am quite happy with the results I've gotten.

    Rated 3 out of 5 by from Not the greatest product Just got my TC few days ago. Using it with Nikon D90 and Sigma 70-200 2.8 HSM Macro. There is a huge gap between what you see in the viewfinder and what you actually get when looking at the image on a computer screen. Images are not sharp as you would expect, colors are distorted arount the edges and after a comparison between images with and without the TC, it seems like a CROP will get a better resault than using the TC. On the other hand, I'm aware that I got it only recently and will experience with it a bit more. Who knows, I might figure out how to enhance the quality.

    Rated 5 out of 5 by from Better Than Expected A good alternative for those of us who dont have big bucks to spend on a lens. My expectations were not very high given the fact that all teleconverters take away some light (and a little sharpness). But after getting some shots that otherwise would have been too far away I think this was a good purchase. With that said, if you can afford to buy a big expensive lens you will spend less time correcting sharpness in your editing software.

    Rated 3 out of 5 by from Met My Expectations I've only had limited use of product so far. I've used it with my Sigma 120 - 400 mm lens to shoot some birds. I found it did a nice job of making the birds larger but the images are softer. I expected this to a degree but some of it could be my eyesight which is not as good as it used to be so I may not be focusing that well. Since I have to manually focus with the extender on I believe I need to use a tripod since the lens and camera are hard to hold and focus at the same time. Since it is my first extender I think I will grow more comfortable with it as I use it some more.

    Rated 5 out of 5 by from Awesome Converter I was hesitant to purchase this teleconverter to use with my Sigma 50-150 telephoto lens for my Nikon D7000 because of all the comments and answers to my question if it was compatible with my lens and camera. I contacted Sigma and they said it would work with no problems. I got it from UPS a couple of weeks later and I am very happy with my decision. The lens works perfectly, when attached to this converter! No manual focusing as some customers thought and I love that I can reach out a bit further now and makes my 50-150 a lot more versatile! Indoors I don't use the converter, but taking action shots of the surf on the North Shore, to hula dances at my daughter's school are great! I would highly recommend this teleconverter to a friend if he/she has the compatible Sigma lens listed on the website.

    Rated 4 out of 5 by from good value I use this with my Nikon D40x, and Sigma 50-500mm to take wildlife photos. It needs a very bright day, and manual focus, but brings the subjects much closer.

    Rated 5 out of 5 by from It works. I use it on a Sigma 120-300 2.8. Sharpness is excellent with this lens. The Kenko 2x I had was also sharp but wouldn't autofocus with this lens using Nikon D300 camera. The autofocus on this lens works great with this teleconverter.

    Rated 3 out of 5 by from Not what I expected I've been using the Sigma 1. 4x for several years with Sigma 150mm f/2.8 macro and the Sigma 100-300mm f/4.0 with excellent results. The image deteriorates a bit but worth it for the 1.4x magnifying. With the 2x you lose autofocus with both lenses (which I knew beforehand.) With both lenses the image deteriorates a little more than with the 1.4x. The corners are fatal with the 2x at 300mm on a Nikon D300. However, the 2x for the 150mm to do macro is excellent. I focus manually anyway with or without extender. You can stack the 1.4x + 2x with mixed results, but the camera does not recognize the focal length and there are too much deterioration of the image. Conclusion: If you are looking for a Teleconverter buy a 1.4x. If you already have the 1.4x, get the 2x only if you do macro. Note: I've read a good review of 2x with the new Sigma 70-200mm f/2.8
