Lenstip reviews the Sigma 100-300mm f/4 EX DG IF HSM APO and writes;
“At 100 mm focal length, there simply is no chromatic aberration for the Sigma at all. No matter which diaphragm was used, its value reaches only 0.05%.”

SLRLensreview reviews the Sigma 100-300mm f/4 EX DG IF HSM APO and writes;
“Sigma APO 100-300mm f/4 EX DG HSM showed outstanding performance in the 100-200mm zoom range. Both center and border quality was top notch throughout the tested aperture range. The overall performance in this zoom range was quite even, with somewhat better results in the f/4-f/5.6 range.”

Photozone reviews the Sigma 100-300mm f/4 EX DG IF HSM APO and writes;
“The Sigma AF 100-300mm f/4 EX HSM DG is one of the most impressive Sigma lenses tested to date. It is able to deliver a near-flawless performance with great resolution figures, low vignetting, low distortions, low CAs and a very decent bokeh (albeit slightly underdeveloped regarding the moderate max.”

Ephotozine reviews the Sigma 100-300mm f/4 EX DG IF HSM APO and writes;
“The constant aperture and faster, quieter autofocusing make all the difference, ably helped by a constant length and internal focus mechanism to make handling a joy. Four SLD glass elements in the construction help to make a nice improvement to the output quality too.”
rating: N/A

Photodo reviews the Sigma 100-300mm f/4 EX DG IF HSM APO and writes;
“Things like distortion are well controlled and measured figures of –0.1% (barrel) at the short end and 0.45% (pincushion) at the full stretch of the lens are negligible and cannot be seen with the naked eye..”

Blazing fast focusing!! | Rating: ★★★★★
“The HSM of this lens is faster than Nikon 80-200 on D70s.. and Sigma 70-200 on 350D. I could say that it is as fast as the EF-S 18-55 kit lens! Do bear in mind, usually wide lenses focuses faster than tele. Besides, the handling and build of this lens is good.” – by Kam L. L. Lily

Great Telephoto Zoom | Rating: ★★★★★
“The zoom and focus rings are wide and move smoothly with just the right amount of resistance. This lens is sharp wide open. At the overlapping focal lengths, the 70-200 at F/4 is just barely sharper than this lens at F/4 (wide open). At 200mm, this lens is actually sharper (200mm is this lens’s sweet spot.) At 300mm, the lens is still sharp wide open, but I like to stop down to F/4.5 just to keep things super-sharp..” – by M. Farrell

Good lense | Rating: ★★★★★
“I use it with a 1.4X teleconverter and it still give me a very good image quality “ – by Yvan Frechette

Sigma 100-300mm F4 – Great lens for the price. | Rating: ★★★★☆
“I bought this lens because the Canon 100-400mm was alittle to much for my pocket book. I have had the lens over 5 months and used it mostly outdoors with a monopod. A monopod is a must, Living next to Yellowstone Park I use this lens alot, however it is alittle heavy, and needs alot of light to get a perfect picture..” – by John Nelson

Sigma 100-300mm F4 EX DG IF Zoom Telephoto | Rating: ★★★★★
“The lens is very well constructed. The mount is all metal. Auto focus is quick and accurate. I especially like the fact that all movement is internal.. Image sharpness at the minimum focusing distance of 71 inches is excellent. Image sharpness on distance shots at f4 is not good but improves at f5.6 and is very good at f8 thru f16. “ – by D. Hills

Excellent optical and build quality. | Rating: ★★★★★
“It handles and balances really well on my Nikon D2X, has solid zoom ring in a great position, smooth movement of manual focus override if needed, near silent use, non-rotating and non-extruding front element, removable tripod clamp.. The long end of this is so much sharper, brighter to compose, and richer in quality (as well as longer in telephoto) than the Nikon.” – by Gary Craggs

Features & Specifications

Sigma 100-300mm f/4 EX DG IF HSM APO Specifications

The Sigma 100-300mm EX DG HSM lens is the ideal telephoto zoom lens for Digital SLR cameras. This telephoto zoom lens provides a large f4 aperture at all focal lengths. With minimal light-fall-off, superior peripheral brightness is ensured. It’s the ideal lens for digital SLR cameras.

SLD (Special Low Dispersion) glass for high image quality.
This lens uses two pieces of SLD glass elements in the front lens group and another two in the rear group for excellent correction of chromatic aberration. High optic performance is demonstrated throughout the entire zoom range.

Inner focusing and inner zooming systems
This lens incorporates an internal focusing system, which eliminates front lens rotation, allowing the use of a petal-type hood and more convenient to use of circular polarizing filter. Since focusing and zooming do not change its overall length, this lens is easy to hold and use.

APO lens
The use of an Apochromatic design and 4 SLD (Special Low Dispersion) glass elements (two SLD glass elements are utilized in the front lens group and two in the rear group) provide for full correction of chromatic aberration and a high level of optical performance.

EX Lens
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.

APO Tele-Converter EX (optional)
High-speed focusing is possible when this lens is used with dedicated APO EX tele-converters (1.4x and 2x). With the optional APO tele-converter 1.4x EX, it works as AF zoom lens from 140mm to 420mm at f5.6. With APO tele-converter 2.0x EX, it works as a manual focus zoom lens from 200mm to 600mm at f8. It is possible to use AE (Automatic Exposure) function, even EX Tele-converters are attached to the lens.
