After nearly 40 years of pioneering new and better ways to capture and portray the ordinary - and extraordinary - Sigma is still creating new avenues of expression with innovative designs and enhancements.
The Sigma APO 170-500mm f5-6.3 DG Lens for Canon Digital SLR Cameras is an ultra-telephoto zoom that offers high performance with both digital or film SLR cameras. Optimized for digital SLR cameras, it features a new multi-layer lens coating and the lens design reduces flare and ghosting. This lens uses one aspherical lens and three SLD (Special Low Dispersion) glass elements for excellent correction all types of aberration, resulting in better picture quality on both film and digital SLRs.
The new multi-layer lens coating and lens design also creates optimum color balance through the entire zoom range. Ideal for sports, nature, wildlife, and landscape photography, this lens features a five-group zoom and rear focus system that ensures high performance stability and ease of use. Since the front of the lens does not rotate, a circular polarizing filter can be easily attached and usedd. A zoom hood is supplied with the lens to prevent flare and ghosting as well as extraneous light that's harmful to image quality. A removable tripod collar is also included as a standard component.
Customer Reviews
Great lens
I can't hold the darn thing steady under 1/100 sec, so with a tripod, it's awesome, otherwise you'll need a steady hand in lower light.
Great for sports
I bought this lens to shoot pictures of my son's football games. It has been fantastic and very clear. Lens creep is an issue but not one that has really bothered me. The price on Amazon was great as I had priced it in NYC and most retailers wanted twice as much if not more.
A great lens for the price.
This is an extremely versatile lens capable of handling many different shooting situations. I have been using this lens for a couple years now and my only complaint is that there is no zoom lock so in between shots where the lens is pointed up at a fairly steep angle you will need to make sure that the zoom is still in it's intended position. I'ts not exactly a walk around lens because of it's size and weight. It is a good lens to have for shooting wild life or taking photos of the moon. I compared it to the Tokina 400mm lens. This lens was far superior to the Tokina. and as good as the Canon EF 400mm f/5.6L USM Super Telephoto Lens. The only advantage is that the Canon had zoom lock.
This lens takes amazing photos. I am very happy with the quality of photos that I get, great color, sharpness and contrast. It comes with a tripod coller, a great carrying case and a hood.
I am very happy with this lens.
