Now that those fundamentals are out of the way, the results and recommendations. I took several photos using this TC mounted on my Sigma 70-200/2.8 and my Sigma 150-500/5.6~6.3. I also attempted to mount my Canon 28-70/2.8L on it, but the fit did not work (it scrapes and sticks and will not lock into place), and thus I believe they are incompatible. I did not test it with my Sigma 10-20/4.5~5.6 for obvious reasons.
AF is maintained throughout the entire range of the 70-200/2.8, as advertised in Sigma's compatibility chart. MF is engaged electronically for the entire range on the 150-500/5.6~6.3, again per the chart. AF through the 70-200 is solid, accurate, and has no degradation of speed. MF through the 150-500 @ 500 is, as one should understand, a touchy process, though it's aided considerably by the optical stabilization function.
Image quality @ 500mm (really, 1000mm) is not spectacular (though what does one expect, given a maximum aperture of about f/12.9). I didn't expect wonders but I had hopes of better. Some of this is inevitably due to my challenge in focusing, which is difficult without a split-prism finder.Read more ›
After shooting with the teleconverter for 3 weeks I decided to send it back. I REALLY wanted it to work. The images were unusable for me. Like I said, I'm not a pixel peeper that obsesses over tack sharp images. Even my wife (a non photographer) asked by the images were blurry. I thought maybe it was my technique. So I mounted it on tripod, in the middle of the day with a fast shutter speed just to see if I could get something that was sharp. No matter what I did I got really soft images with what looked like a dreamy blur to them (think cheesy 1980s portraits) and color fringing.
I love Sigma glass. Its high quality, professional level equipment that will stand up to professional abuse. I shoot the Sigma 70-200mm 2.8, 18-50mm 2.8 and the 30mm 1.4. Amazing glass at a fraction of the cost as Nikon or Canon. But this 2x converter does not hang with the rest of them. Maybe I just got a bad copy but it sounds like others have had the same experience. Guess I'll just need to save up for the big boy: Sigma 50-500mm.
Hope this helps.
The only reason I couldn't give this converter a perfect mark is I can't use it with my other Nikon lens.

I use the Sigma 2x Tele Converter with my Sigma 50-500mm f4.5-6.3 APO lens and Canon bodies, so it changes to 100-1000mm, and if on crop sensor that makes it 1600mm that's some... Read morePublished 15 days ago by Robert Weller

Works well with my Sigma 150mm-500mm lens. However, it is very limiting with other Sigma lenses. It will only work with a few of the Sigma lenses. Read morePublished 11 months ago by Lisa
Nicely done again Sigma! It's compact and light which is good because when attached to my pretty heavy 70-200mm f/2.8...it.could have led to shoulder surgery! But it won't. Read morePublished 12 months ago by Jason Aldridge
