Lens

Lenses are easily more important than any other part in your camera. Finding the right lens for your camera can be a daunting task. A good lens is ideal for proper projection of the image on your imaging sensor. For beginners, lenses and related factors can be quite confusing. 

Here are the key factors that users should understand before buying a lens.

1.      Focal length

Focal Length is the angle of view of the lens. Focal length is measured in mm. A higher number offers a bigger zoom, while a lower number is perfect for wider shots.

2.      Aperture

Aperture is the measure of light that the lens can effectively gather. Lenses which have larger maximum apertures can gather more light. Lower maximum aperture means less gathering of light.

3.      Image Stabilization

A lot of lenses feature optical stabilization units that counteract the blurring effects caused due to handshake or camera motion. Image stabilization can be handy in most conditions. However, users should keep in mind that image stabilization might not work if the camera is violently shaken while capturing the images or videos. It can work only till a certain level of camera shake.

  1. Format

Format is the sensor size of the lens that it is designed to work with. Different cameras use different sensors; you should always make sure that the lens will produce an image that is large enough to be able to cover your image sensor.

  1. Lens mount

A lens mount determines whether the lens can physically fit with your particular camera model. You should know the mount which your camera uses before you buy a lens. Usually, camera manufacturers make lenses with proprietary mounts that fit only their devices. There are even third party lens manufacturers that provide similar solutions.
