What You Should Know About Your Digital Camera Lens

The lens is the most important part of a digital camera and there’s every reason why camera owners need to get to know this component. Lenses control what a camera captures in terms of the image, perspective and quality and how much light can get in. Adjusting this part plays a vital role in capturing quality images.

The lens is described through its focal length which can either be the single type or the one with various ranges. A lens that has a single focal length is known as the prime lens while the type that has a range of focals is referred to as a zoom lens. Most digital cameras today feature zoom lenses including the point and shoot models.

Cameras having a zoom lens can accommodate tamron camera lens price different focal lengths within its range. This can be done just by turning a ring around its body. In most cases today, though, this can be done automatically with a click of a button.

Through the focal length, the angle of view for a specific camera sensor size is determined. For instance, a lens with a full-frame sensor can give the same angle of view similar to a 35 mm film camera. A smaller sensor, on the other hand, means that the angle of view is smaller as well.

A short focal length means the angle of view is greater while a lens with longer focal length features a smaller angle of view. With a wider focal length, you are able to take an image at a closer range. With a wider angle-of-view, on the other hand, you can capture a larger subject at a distance. If the angle of view is narrower, you can take a small subject from a specific distance.

Another part of the lens is the aperture. This is the opening inside the lens that allows light to pass through. Wider apertures are also known as bright and fast apertures because of their ability to let more light in. With more light, faster shutter speeds can be achieved.

Apertures are indicated through numbers. A small number means a large aperture such as F/2while a large number implies a small aperture. With prime lenses, they only have one particular aperture. Zoom lenses, meanwhile, have two or more apertures.

The mount is also a vital component of a lens. This is the one that connects the camera and the lens itself. This is often used with interchangeable lens, some of which can fit different types of digital cameras. They can be used directly or through a special adapter.

When using mounts, make sure that the lens is also compatible with the camera. It may be that the lens and mount fit together but the lens is not suitable for the camera due to a different sensor size. Most camera manufacturers produce their own lens mounts that can be used with the same brand of cameras only. But it is also possible today to get a mount from a third party manufacturer which can then be used in varying types of lens and camera.
