Camera Equipment Guide | How to Choose the Right Lens for Your Camera
Camera Equipment Guide | Lenses are probably the most important part of your camera setup; they make or break your photos. They control the image that’s transferred onto your imaging sensor, and ultimately what photos you are taking home. Once you’ve bought a new interchangeable lens camera you’ll definitely start thinking of adding an extra lens or two to your inventory. When you buy an interchangeable lens camera you’re part of a relationship with the specific hardware mount determined only by the brand.
Nikon uses an F and CX mounts, Canon EF and EF-S, Sony A and E mounts depending on the type you choose. Be advised that even though they are all interchangeable lens cameras, you cannot use Nikon glass on a Canon and vice versa.
Zoom vs Prime | Camera Equipment Guide
A zoom lens is a lens that has a specific range of focal lengths available to the photographer in the one lens. These have become more and more popular over the past few years as they are obviously a very convenient lens to have on your camera as they mean you can shoot at both wide and longer focal lengths without having to switch lenses mid shoot. A prime lens is a lens that has one focal length only. These come in a variety of range from wide angle ones through to the longer telephoto ones, all depending on focal length. Both prime and zoom lens users strongly defend their choice and will argue at great length about their choice of lens.
Speed | Camera Equipment Guide
Faster lenses have wider maximum apertures – f/2.8, f/1.8 etc. They let in more light and enable you to achieve faster shutter speeds. The only negative side to faster lenses is that they’re heavier and more expensive. Faster lenses allow you for shallower depth of field. This means that when you’re focusing upon a subject the foreground and background will be blurrier. Of course having a very fast lens means that this can actually make focusing trickier as your depth of field is very shallow.
Focal length | Camera Equipment Guide
Usually shown in millimeters (mm), this is the basic description of a photographic lens. It is not a measurement of the actual length of a lens, but a calculation of an optical distance from the point where light source rays converge to create a sharp image of an object to the digital sensor or 35mm film at the focal plane in the camera. The focal length of a lens is determined when the lens is focused at infinity. This number, in combination with the camera’s sensor size, determines the angle of view covered by the lens, with smaller numbers indicating a wider angle. Zoom lenses are named using two numbers which indicate the maximum range, for example 18-55mm for a typical kit zoom lens.
Lens Mount | Camera Equipment Guide
Camera manufacturers usually make lenses with proprietary mounts which will only fit their devices, sometimes having multiple lens mounts for different camera lines. Each camera maker uses its own proprietary lens mount, considering that lenses can’t be swapped across brands (a Canon lens won’t fit on a Nikon body, for example, and you’ll cause damage to lens and camera if you try).
Format | Camera Equipment Guide
In addition to being able to mount the lens on your camera, you need to be sure it will produce an image big enough to fill the image sensor. Due to the fact that various cameras use different size sensors, manufacturers produce specific lenses to work with. Lenses designed for full frame will also work on APS-C cameras. However APS-C lenses won’t work properly on full-frame cameras, and in the case of Canon, it’s physically impossible to attach an APS-C-optimized EF-S lens to a full-frame camera. This is something worth thinking about if you are thinking of upgrading to a full frame camera body in the near future.
A lens is an extremely important component in photography, and as a photographer, you want to have not only great skills but you want to use equipment and parts that will not only make your job easier, but that will help to produce the best possible photography. You should have the right lenses for the diverse situations you will encounter. The front element of your lenses is very delicate to physical damage so it makes sense to protect it with a skylight or ultra-violet (UV) filter. Always remember that changing a scratched filter is cheaper than buying a new lens.
