Sigma 1.4x EX DG APO Tele-Converter AF for Canon EOS Cameras

It worked great on pictures I took of an Osprey nest that I've been watching. Even without the automatic focusing.

Haven't had enough light to use yet (sweet spot for this 1.4X teleconverter is f/11-f/14). The build quality is excellent though!!!

This teleconverter is worth it's money. I used it with the sigma 180mm f2.8 macro OS. Autofocus and image stabilizer work fine. Can also be combined with older non-CPU lenses to extend their tele range and seems to work ok in terms of image quality and automatic exposure on the d810.

I have Sigma APO70-200 F2.8EX DG HSM and APO150-500 F5-6.3 DG HSM lenses. The 70-200 worked very well with the teleconverter and the A6300/LA-EA3 or A6000/LA-EA4, including autofocus. The 150-500 worked with the A6300/LA-EA3 or A6000/LA-EA4, but only in Manual Focus. Based on info on Sigma's web site (http://www.sigmaphoto.com/lenses/lens-resources/teleconverter-compatibility), I wasn't sure that the lens/teleconverter/E-mount converter combo would work. I am pleased to report that it does work fully with the 20-200, and in Manual Focus mode with the 150-500. Sigma says explicitly (in a private e-mail) that the MC-11/TC-1401/150-600 will not work together. My experience with my setup suggests there are no technical impediments to making the combo work, if they chose to do so.

Small, lightweight Sharp and autofocus performs well

It works nicesly with my Nikon D7100 and my Nikor 300mm F/4 lens. Works with autofocus, takes a little bit more time than without the TC, but does the job.

This TC is compact, very similar to my Nikon TC of the same magnification. So it can fit on the lens and be left there if desired and it doesn't really add much to it in terms of weight or length but it adds a lot in terms of focal length and image quality. I cannot tell a difference in using it and using my 120-300 Sport in "native" mode without the TC. I have a 168-420 f/4 zoom with the same IQ as the 120-300 2.8. Wow. Thats with a D800; with my D7100 and the APS-C crop factor its pure bonus. Solidly built, good looking item giving up nothing but a stop.

When I bought this and originaly got it I had a Sigma 100-300mm lens, everthing was peachy. But the Sigma 100-300 turned oud to be a bad copy. I bought a Nikkor 300mm AFS f/4. Now the problem is the Sigma TE was not talking to my D600 body properly, I could not tell when I was using the TE or not in the EXIF data. Optically it seemed quite good, mechanically (mounting fit) seemed very good as well.

Originally purchased to use on a Sigma 100-300 f/4. That didn't work out as that lens turned out to be a very poor copy of a lens which was considered very very good by many. I have used it on my Sigma 150mm f2.8 Macro and it works very well there. Now I'm waiting for a new Nikkor 300 f/4, so the 4 star rating is because I figure that pairing is how I will know how good this TE is optically. In all other ways this is a well built piece of equipment.

Very hsppy with the added range and output of the units

Sigma tele-converter will mount up with my canon lens. But it will not mount up to my Sigma 17-70 2.8 lens.Be wear! It has its good range and bad range.Mostly good.

Very Nice output for the price

I've got a generic Kenko TC but the camera doesn't see the change in aperture or focal length. This works perfectly well on my two Sigma telephoto lenses.

I use the Sigma 1.4 tele-converter with a Nikon 70-300mm VR, f4.5-5.6. Since it reduces the amount of light autofocus is not dependable past 200mm. This is not a complaint, just the way it works with a small aperture lens. The tele-converter will not mate physically with my Nikon 16-85 VR or my Nikon 50mm, f1.8. I have tried the tc on my Sigma 150-500mm but the clarity became too poor to be useful. Bottom line, the Sigma 1.4 tele-converter does what it is supposed to do at a very nice price.

Typical of the better Sigma lenses, this teleconverter does its job extremely well. As indicated though, it is designed to be used with Sigma lenses. I use it consistently with their 100-300 zoom for wildlife and it allows auto focus with my Minolta. I would have preferred that it work with all my lenses but after using it once in the field, I was hooked.

Sigma lenes shine with Sigma TC's

The converter are made only for SIGMA-lenses and did not fit my MINOLTA-lenses. I sold it.
