Liquid Photography

There are many types of lenses which are designed as per the requirements one needs underwater. Some lenses are designed keeping in mind the challenges one face in underwater photography.

The types of lenses are-

1. Prime Lenses – A 20mm, 60mm and 100mm lenses are the examples of prime lenses. A lens which is directly attached to the body of the camera is known as prime lens. Prime lens are optically superior lenses. The only disadvantage of these lenses is that they cannot be removed during a dive.

All cameras have a lens. There are compact cameras known as point-and-shoot cameras which have built-in lenses and they cannot be changed. On the other hand there are dSLRs which gives the flexibility to change the lens. Hence dSLRs cost more and you have to purchase one or more lenses. Lenses involve many complicated terms such as 18-55mm, zoom lens, telephoto lens, fisheye, macro lenses and many more.

In the good old days the cameras came with a normal lens – 50mm. These lenses were strong and rough but provided high quality shots. However these lenses provided low quality zoom and had other problems.
