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.

HSM (Hyper Sonic Motor) ensures a quiet, high-speed AF
The AF drive for Sigma SA, Canon and Nikon cameras is equipped with a silent, responsive and high speed HSM (Hyper Sonic Motor), which also provides full-time manual focus function.

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 (The 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.

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 F5.6. With APO tele-converter 2.0x EX, it works as a manual focus zoom lens from 200mm to 600mm F8.
It is possible to use AE (Automatic Exposure) function, even EX Tele-converters are attached to the lens.

Boosting you telephoto power can get prohibitively expensive, but here's one optic that'll enable you to tackle a wide range of distant subjects without paying silly money. Granted, this is no cheap lens, but when it's married to a DSLR with a cropped sensor it really will pull distant details in. Of course, the pay off with the with the extra telephoto power is the aperture, but at least it is constant thought out the focal range.

The Focusing with the HSM motore is also impressivly quick, accurate and quite- something that can come in very handy for thouse shooting timid wildlife. Optical speaking, you'll gte the very best results in the central apertures, which may necessitate a tripod of faster ISO settings, but there's very litle diffrence between the definition at the centre and the edge of the frame. In addition, distortion is well controlled thanks fo the use of four soecial low-dispersion glass elements.

This won't be suitable for every telezoon worker, but if you like the idea of this focal range, then chances are you will love this lens.

Sigma 100-300mm F4 - Great lens for the price., Monday, 30 July 2007

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. Its not a L lens but it has its qualities that are very close, this lens doesn't get the attention it deserves for outdoor photography.

If you are looking for a good F4 lens without spending over $ 900.00 this is a good alternative. If you shot in low light tripod is a must.

Overall I am very happy with this lens, I would give it 5 stars if it handled low light better.

I bought this lens to use with my Canon 30D for high school sports (soccer, football, baseball, etc). I already had the Sigma APO 70-200mm f/2.8 EX DG HSM Lens for Canon Digital SLR Cameras and needed more focal length. Like the 70-200 F/2.8, this lens is big, heavy, and built like a tank. The bare lens is about an inch longer than the 70-200, but the 100-300's hood is longer than the 70-200's hood.

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. Up to 250mm, I would not hesitate to use it wide open.

This Sigma lens has HSM which means the focus is fast and quiet. The lens focuses a little slower than the 70-200 F/2.8, but I've found that the 30D is more of a limiting factor in focus speed than the lens is. Servo tracking is very good with this lens, the only time it can't keep up is when track runners are sprinting straight at me (although again, I think the body is the limiting factor here.) For almost every other situation, the focus will definitely keep up.

All in all, this is not an indoor lens by any means, but as an outdoor sports (or wildlife/nature) lens, it is awesome.

Blazing fast focusing!!, Friday, 10 March 2006

The HSM of this lens is faster than Nikon 80-200 on D70s (it hunt around 2 times when i tried to focus on my frd who was in blue/white stripes at opposite side of a tennis court walking to me) and Sigma 70-200 on 350D. How fast is that? 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. Tripod mount made of metal. Holding the tripod ring and focusing ring feels great. I shaked this lens on intention, and hit it to a table... ( this is not my lens :P ) It works same well and not even a tiny scratch is done on the lens after all
However, it has some draw backs. 300mm focal length is a Bit too long for me. F4.0 is a bit too narrow to use with 300mm indoor ... your photos may be blurred if you handheld them
Conclusion: It is a perfect lens (especially sports) if you use it under bright sunlight.
