Sigma 50-200mm f/4.0-5.6 DC IF SLD Optical Stabilized (OS) Lens with Hyper Sonic Motor (HSM) for Canon Digital SLR Cameras

This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabilizer function. The lens incorporates SLD (Special Low Dispersion) glass in the front lens groups and is equipped with an inner focusing system to provide high image quality throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures quiet and high-speed auto focus. The OS (Optical Stabilizer) function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds up to 4 stops slower than normal for steady, handheld photography. For Sony and Pentax mounts the built-in OS System allows the photographer to see the stabilized image in the viewfinder and can be used as an alternative with cameras having built-in image stabilization. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range. This lens has a minimum focusing distance of 43.3inches (110cm) throughout the entire zoom range and a maximum magnification ratio of 1:4.5. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters.

Good budget option Tele Adhi Sigma has very good product in this segment, much better than the cheapo 55-250mm supplied by Canon. Good build, good features (HSM is if the design). And the lens in the lower focal lengths and good bokeh sharp. The only drawback is that the lens is not sharp at longer focal lengths, but still very useful. 13 of 13 people found the following review helpful. Sigma 50-200 OS photogai By irJIM is a good budget lens, but I'm still trying to get it then to push its optimum performance. I have three lenses Sigma DC lenses are two, while the EX out preform my other only in detail, clarity when enlarged. Focus is fast, focus and zoom rings are smooth, but I like the sharpness was better during an increase in comparison with my Sigma lens. Nikon 55-200VR seems to be gaining a bit more sharper detail in the image when enlarged, but they are about the same size, Sigma better built. I wish I was closer to a lot of zoom focus range Minimum OS (Optical Stabilizer) is doubtful, sometimes it works well while other times it is very light double blur, even when the aperture seems sufficient 1/250- @ @ 200 mm a / 320th time operating system, sometimes I'm angry large images at slower shutter speeds up to 1/10th of a second hand fed OS. I was @ 200mm F-16 and F-11 @ 50 mm is the sweet spot is another way to default image, does not matter. I still love my Sigma'll's notes are EX. 9 of 9 people found the following review helpful. D3100 Nikon and Sigma 50-200 mm OS HSM lens compatibility By Jane Austen'm writing this comment for all the "newbies" out there have a Nikon D3100, which is tired of the included kit lens, because it can not do 'Reach "additional issues. This criticism applies to people who have written, written, and written reviews for lenses, which details the specifications of this lens "high price" lenses you keep whining about Blah Blah Blah in comparison! Save us from our precious time and if you have money to buy lenses at high prices. This is pretty simple. You all know that is strong in this price range of consumer markets and pr0-sumer-based. If you are a "pro" then go with high-end goals, I'm sure you have enough money with your photography. Also, maybe you want to add this type of case or even the name of your digital SLR, so that newcomers will have a better idea, if the lens or any other type of lens will be responsible for their DSLR body functions. First question is, this lens 'autofocus' with my Nikon D3100. The answer is YES! It has the distinction HSM, which is actually a replica of the Nikon AF-S. In addition, also has an internal motor that produces hard and fast "auto focus" that self-focus on a Nikon D3100. Secondly, it will support the vibration function of the decrease? The answer is YES! It has optical stabilization (OS) function, which is the equivalent of Nikon's VR. The characteristic of this operating system is very much appreciated the longer focal length lens with the placement of the stability of the poor, reduce camera shake expansion of the lens. The third question, fit the Nikon F mount D3100? The answer is YES! Without a doubt! It also has the function of the SLD (something about how the lens will do anything!), Which produces high quality pictures. Nikon's counterpart to this is emergency department. Do not worry about DX (a type of format), as Nikon's DX format D3100 and this lens is designed for digital. These are basically "owner" is similar to the Sigma 50-200 mm DC OS HSM SLD compared with 55-200 mm Nikon ED AF-S DX VR. To the extent that these two have much in common. They also have differences The main difference, first, of course, is the price. Nikon is $ 50 more. The second mounting plates. When I had the opportunity to go to best buy and have a real sense and feel of the Nikon 55-200 mm, which was more.
