Excellent lens
I purchased this lens to use with my Olympus E-500 body. I was skeptical as to the image quality because of the low price. I'm glad I decided to give it a try. It takes excellent sharp pictures. I would highly recommend it! ... Read more

The Sigma 28-200mm zoom macro lens for Nikon Digital SLRs
The Sigma 28-200mm zoom macro is an excellent lens for the typical portrait or landscape photo.I was a bit disappointed in the macro feature for a couple of reasons.While I realize that no telephoto lens can really take "macro" images, I was used to the 28-135mm Sigma macro that I have for my SLR film camera. A friend does have a 28-135mm for his Nikon digital SLR, so I was hoping to get one.That lens has a macro switch and a image ratio of 1:2.Unfortunately, Sigma no longer makes the 28-135mm lens, at least not for digital cameras.So I selected the 28-200mm macro with an image ratio of 1:3.8 and no macro switch.With my old 28-135, I could use one lens for just about all my photos; I will not be able to do that with the 28-200.Even with these exceptions, however, I do find the 28-200 lens to have very good optics and flexibility. ...

junk
do a little research and don't be fooled. Sigmas are generally a hit or miss thing for the lens quality. And worse off if you travel 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

Sharpness High Price Low for this Lens
There are some that slam this lens and others that praise it.You have all heard the value of the 50mm 1.8 right?This Sigma lens isclose to the same value as far as cost vs sharpness.It is not as fast as a 2.8 lens but it also is not as expensive.If you can afford it get a 2.8 lens but if not then this is the lens you want. It is very sharp but does become soft at outer edges ... Read more

An excellent lens.
I won't repeat what other reviewers have said but I do want to say that this is a wonderfully sharp, bright, and very well built lens. Great lens with one important flaw
I love this lens. It is very fast and extremely sharp. However, after getting the lens I had to send it to Sigma in NJ for a software adjustment so that it would not freeze on my F100.Seems that after about three minutes of HSM focusing on F100s the Sigma lens freezes. It can be unfrozen by turning the power on the camera off and on, but that's a pain. Sigma repaired it very quickly and I now love it. I use a 1.4x Sigma converter with it and very much like the combination. A great lens with great features.
Having used the Sigma 70-200mm F2.8 EX HSM lens for portrature and wildlife work in Costa Rica recently, I can highly recommend this lens. The lens is very strong and well built, extremely fast, silent, and sharp. There are times when the lens will hunt a little bit when focusing, but this is not enough of a problem to cause you to miss a shot or cause a problem. The ability to imediately manualy focus the lens without having to switch to manual focus is not only a great convenience, it is absolutely a necesity when photoghaphing wildlife in the jungle, or even through the brush or in a tree in your own backyard. If your camera should focus on the foreground clutter instead of the desired subject matter, all one has to do is to rotate the focusing ring to focus on the subject, and shoot. I have found this lens to be extremely sharp and acurate over the entire frame area. The F2.8 light gathering ability is excelent, alowing you to add the Sigma APO 2X EX teleconverter to have a fully auto 140-400 F5.6 lens as well for little more money. Using this combination as well I have noticed no decrease in sharpness of image quality, although focusing may be slightly slower. In continuous focus mode this combination still had no trouble keeping up with birds in flight, although a tripod would be highly recomended. A nice feature is the tripod mount which can be used to grip and hold the lens and camera while shooting, or in less than a second can be detatched from the lens if so prefered. The camera can also be rotated a full 360 degrees within the tripod mount instead of the stndard 90 degrees of most other brands of lenses. The lens comes complete with with end caps, a padded soft side storage case, and even a lens hood, specialy designed to eliminate vigneting- at no extra charge. Although normaly dedicated to Nikor lenses, after inspecting and using this lens I found it to be equal in quality and better designed (in my opnion) in some areas than the Nikor 80-200 F2.8 silent wave lens. It is also smaller and lighter than the Nikor lens, a big plus in all day use, in or out of the jungle. On top of everything else I was able to purchase the Sigma lens for...less than the Nikor lens. A great lens at a great price. ... Read more
