If you are shopping for the best camera, pay more attention to top camera lens 2013 from Nikon camera lenses reviews. On the front of a camera lens there is a glass lens that focuses light into the camera body and onto the film. Inside the lens body, there are several other optical lenses that further refine the image. These lenses are sometimes called "elements". In front of the first optical lens, there is a small ring with screw threads cut into it. These screw threads allow for filters and other accessories to be easily attached to the front of the lens.

Each lens carries a second mm rating that tells the diameter of this front attachment point. Each lens has a focusing ring. This is a section of the lens that rotates to allow the photographer to focus the image. On automatic cameras, this ring is moved by a small motor within the lens whenever the photographer presses the shutter release button halfway down. These rings are usually marked with guide numbers showing how far away a subject is when focused. Each lens that has zoom capability has a focal length ring. This ring allows the photographer to zoom in or zoom out on a subject. Lenses are often described by their focal length. For example, a lens may be called a 70-300mm lens. This indicates that the lens can zoom from 70mm to 300mm. Example of images taken with different focal lengths.

Nikon Camera Lenses Reviews The preferred “workhorse” among many professional photographers since 2003, Nikon’s AF-S 70-200mm f/2.8G ED VR model was also my favorite lens in the Nikkor series. It was just about perfect in all aspects, except for some slight corner softness at wide apertures with a full-frame digital SLR. Some reviews also mentioned less than ideal flare control, but frankly, that was nit-picking. In any event, Nikon has replaced that earlier model with a new VR II-designated version boasting a superior optical design, more effective VR stabilizer plus some other benefits. An f/2.8 lens is desirable for several reasons. The very wide maximum aperture allows for faster shutter speeds than the more typical f/4.5-5.6 zooms. That’s valuable in low light or action photography, allowing us to use lower ISO levels for superior image quality. A maximum aperture of f/2.8 also allows more light to reach the AF sensor for faster autofocus. And AF is maintained even when a 1.4x or 2x teleconverter is used. Granted, this 70-200mm f/2.8 lens is very large and heavy, but it’s built to tolerate pro-level abuse and it’s also dust- and moisture-resistant.

Pipping the Nikon D800/E by one percentage point in the overall count, the Olympus OM-D EM-5 won out in this year's poll by a whisker. Although a very different camera to the D800, the OM-5 EM-5 is a seriously impressive product. With the launch of the E-M5, Olympus harks back to one of its most fondly-remembered camera systems - the Olympus OM range of 35mm SLRs. Initially the E-M5 looked like it might simply be an upgraded E-P3 with a built-in viewfinder, but in use it proved much more than that - probably the most competent enthusiast mirrorless camera so far. When we reviewed the OM-D in April we commented on its excellent image quality which at that point set a benchmark for Micro Four Thirds cameras. As we'd expect from Olympus it's also an incredible customizable camera, and with the huge range of compatible Micro Four Thirds lenses available it's also one of the most versatile. About the only thing the OM-D can't do well is continuous autofocus, but if you can live with this limitation, it stands as one of the best cameras currently on the market, and a worthy winner of our poll.
