The lens EF-S mount is a derivative of EF mount created for a subset of Canon digital single-lens reflex cameras with APS-C sensors sized image. It was released in 2003. Cameras supporting the EF-S mount are backward compatible with EF mount. Only the Canon cameras sensor APS-C size released after 2003 are compatible with the saddle. All other cameras do not support it. The "S" in EF-S means "again short approach ", which means that the rear element of the target is closer to the image sensor than regular 35 mm SLR camera. The proximity of the element back to the image sensor greatly enhances the possibilities for wide angle lens and wide angle, allowing them to be smaller, lighter glass (Less), faster (larger aperture) and less expensive. The current majority are Canon EF-S wide angle. Lenses designed specifically for size sensors APS-C has been optically designed to provide a narrow light cone to match the sensor. However, not all such lenses require more focus back short, and may depending on the standard EF mount. These lenses give appreciable vignetting if used on a 35mm film camera or sensor. 3.5-5.6 max media openings are f3.5 at 18mm focal length and F5.6 at 55mm focal length 4-5.6 mean maximum aperture f4 at 55 mm focal length and F5.6 at 250mm focal length lens that is half built in image stabilization Without going into all the specifications of the lens and I like the comments of two lens kit for $ 1999. I have no taste of a zoom with a wide dispersion starting going wide to telephoto. In addition, the kit of 2 lenses up to 250 mm compared to the other 200 mm. You will need to investigate all the specifications of the lens and comments. I I'm not sure why the lens 2 has a much lower price. Are all the original objectives of Canon?

Which goal is better Canon EF-S 55-250mm f/4-5.6 IS or Sigma 28-300mm F3.5-6.3 DG for Canon XSi?

I am new to photography and it my first digital SLR. I have the kit lens 55mm-18 that accompanies it, but I'm looking for something with a little more length coordination to take some pictures of wildlife. My plan is to use this device and the objective nature especially wildlife and portraits. I'm looking for ideas on what everyone thinks is a better target these situations and I would be willing to make other suggestions. In the list you can see that I'm keep prices down at least $ 500.

The Canon for two reasons … continue to the end of the existing lens … 55 mm and therefore do not "overlap" in focal lengths. Two and perhaps more pressing, Canon lenses are really the best lenses for Canon cameras has … contact lenses will last held by five or six bodies to be updated every four or five years to adapt to digital SLR technology. I, for example, have one month old Nikon D300 that uses two lenses all Nikon has done since 1959, but for a handful of fish-eye lens specialists. My oldest is a 105 mm Nikon lens is the end of 1960. I use it when making the order / Photos glamorous.
