This ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows photographers to bring the subject close and short perspective. Sigma's original OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower. It is ideal for sports, wildlife and landscape photography with handheld shooting. Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with a rear focus system that minimizes fluctuation of aberration caused by focusing. The super multi-layer lens coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The addition of the (optional) 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 210-700mm F7-9 MF ultra-telephoto zoom lens or a 300-1000mm F10-13 MF ultra-telephoto zoom lens respectively. A removable tripod socket (TS-31) is included as a standard component.

I was so ignorant when I bought my first two goals for my Canon camera. It has nothing to do with a Canon camera lens or a second or a third party. I really do not even know what I'm saying, until it cost me money on a lens I could use my new Canon camera. The camera lens at the time of purchase to know what are all these numbers, abbreviations and letters. Do you know what is a telephoto zoom lens verses. Or what is a telephoto zoom lens is and what an objective third party? Know ifThe lens of camera you have or if you put the camera you can buy along the road. There is no data to buy the same type of lenses for the new camera, if you can guarantee that the lenses are compatible with the new camera.

I bought a Canon 50D and then a year later I wanted a Canon 5D and if I leave my wide angle lens I bought for my 5D to 50D, it does not fit well. The lens is mounted on the new camera is fine, but there was a large dark ring, when I looked throughthe viewfinder. I was with the thought that I became a new wide-angle lens for the camera I had just bought for landscape photography purchase sick. My thought was a Canon of not knowing a Canon camera, high-end cameras that have different mount brackets. 400 f/4.5 - - I've never given much to all the letters and numbers with a Canon EF 100mm f/5.6L IS USM telephoto zoom lens attached thoughts. So let me break you.

I prefer my Canon camera so when IBuy Canon lenses for EOS cameras there are, the electro optical systems. But the Canon EF Lens for Focus on the Electro. Canon lenses have built the engine of the lens. EF lenses are compatible with all EOS cameras. And there is also an EF-S series of Canon lenses and they do not fit all EOS cameras. The EF-S have a smaller image circle, take the exit towards the camera and does not fit full frame Canon digital bodies like the 5D or 1Ds. If you are seeing is the 100-400Focal length of the lens and is measured in millimeters. F/4.5 to 5.6 which refers to the station F. This is the mesh size of the lens, the smaller the number, the faster the lens. And what do you mean with a faster lens, the opening is bigger and requires less light for recording in low light conditions.

The L, which is indeed the case is synonymous with luxury, some people clam stands for low dispersion glass UD. I have several articles in which these are the two most important answers to read. But no matterwhat it stands for the L actually means that this is a career goal. No matter what sporting event you go to what event or place that is photographed by a photographer making a living with his camera and lens. If there is shooting with a Canon camera, the use of an L-series lens This is identified by the red stripe that runs around the front of the lens. The IS is the lens is equipped with an Image Stabilizer and USM stands for Ultrasonic Motor. ATelephoto lens to zoom in so much farther and are closer than they are. A zoom lens offers strictly as a matter similar to a point and shoot camera with zoom.

When someone refers to a goal as the first party or third-party lens, which means that it is one of the first lens portion is produced by the camera and probably the best solution for your camera, but usually is more expensive than a third lens. A third-party lens, you guessed it, consists of aLens manufacturers make lenses for all camera manufacturers. These lenses are more compatible with the camera and will do a great job for you and are usually a few hundred dollars less than the first party lenses. And, I like to save a dollar, but the next goal I buy for my Canon 5D, a first-party lens.
