Editorial Review

The Sigma APO Teleconverter 2x EX DG for Minolta 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 2. 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. ...

Good wide angle, very bad optics
I ordered this lens because I wanted the widest angle without getting a cropped lens (the Canon 10-22).I have had great luck with Tamron 3rd party lenses and the price was great so I thought what could be better?I should have paid more attention to what everyone else said about quality control.On the good side the wide angle is truely fantastic (can't wait to see the 10-22).Also the color responce, saturation, and contrast are absolutely stunning.Comes out right with no post production needed.Unfortunatly the good ends there.As far as sharpness, clarity, and focusing the camera is simply not usable.It is simply the worst quality lens I have eveer used.Even manually focused, stopped down, high shutter speeds, and clear skys this lens is so blurry and fuzzy you think you took it with a cheap camera phone.Not to even start about the chromatic ab., noise, and fringing.None of my images were usable at all.I decided that wasn't worth the price and I didn't want to deal with sending it back to Sigma 2-3 times like others had when I could get a Canon 10-22 for a bit more and know I will get good quality.Don't get this lense, it isn't worth the money.(If you are using a full frame camera like the 5D then it would be a shame to put such a bad lens on it.Get the Canon 10-22.Not to mention the Sigma really is huge with rather poor quality construction.The zoom and focusing ring were also almost impossible to use.

Unique Ultra-Wide Angle Lens But Poor Sigma Quality Control
There's nothing else this wide for use on a full-frame 35mm camera or digital such as the Canon 5D.It's so wide on a full-frame that you can almost see behind you (well not quite, but close to 180 degree field of view).It is not a fisheye, so straight lines stay straight. There is some minor vignetting at 12mm but less than the Canon 17-40 L-lens I had at 17mm. This lens is pushing the limits of physics so it is not as sharp as some lenses but it takes in so much more of the view and provides a crisp image all the way to the corners.
Professional 12-24 lens
I use this lens primarily for architectural work. It's rugged, fast focusing, and most important, distortion free (i.e., straight lines stay straight). Dramatic design, built for full frame use if (when) you decide it's time to go that way. It's also performed extremely well for landscapes....even some shots at weddings. My most frequently used lens. (Hint: on the APS-C format digital SLRS, you can leave the accessory ring on the lens - it provides additional flare resistance, and there is no vignetting.) ...

Sigma's 1.4X APO teleconverter lens features gives you a high-performance optical design with five elements in three groups. It is optimized for use with long telephoto and telezoom lenses, and is ideally suited for use with the 70-200mm f2.8 APO EX HSM zoom lens. Using 10-pin electrical interfaces, there is no loss of autofocusing speed when these teleconverters are used with compatible HSM type lenses. This model is dedicated to Nikon AF SLR cameras. ...

Excellent Teleconverter
Works wonderfully with my Sigma 70-200 f/2.8 HSM. Fast, very sharp. Seems to be very well made. A great addition to any fast Sigma lenses.

Excellent converter.
I use this converter on my Sigma 70-200 f/2.8 HSM Nikon mount.I used it first last fall at the Petit Le Mans at Road Atlanta and was very impressed with the results. Aperture is reduced to f/4, which is still a bright finder, and autofocus operation is not negatively effected. All electronic functions such as HSM and D coupling still work. Very sharp from my experience. ... Read more

Can't beat this lens if you want something flexible.
I love this lens.Let me say that I'm writing this from a amature/enthusiast point of view.I'm not a professional photographer.I've tried a lot of digital cameras, though, and this lens is certainly better than any of the Non-SLR cameras with this kind of zoom range.I guess if you're a pro you can see some imperfections but I can't find them.

never
do a little research and don't be fooled. Sigmas are generally a hit or miss thing for the lease quality. And wordt off if you travel and with the camera..seals are not at all reliable. Last but not least go ito a store and compare the drive noise on this unit to any other brand...very very noise...sorry i can not recommend them. Nikon, Tamron, Tokina...I personally prefer Nikon and Tokina...good luck

Good on a digital SLR
My copy of this lens gives good image quality, though it does have slight barrel distortion (things near the edge of the field of view bulge out very slightly). This is typical for this wide of a lens, and isn't noticeable unless viewing something with lots of straight lines near and parallel to the edge of the frame. What a wonderful piece of glass
To echo what is said about the new release SIGMA lenses - WOW.Read more

Fantastic lens for the price
I had the pleasure of using this lens for about a month.
GOOD quality, RELATIVELY cheap
I'm D100 user, and I have been watching this lens for a year. But, the old version of this product (NOT DG) had a problem with focusing accuracy, So I hesitated to buy the old version.
