Cameras are optical devices for recording images as individual still photographs or as part of a series of ideas, such as in a video. Cameras use electronic sensors or photographic film to capture visible light or electromagnetic waves. Today, most people own a camera in some form, although the increasing acceptance of smartphone cameras represent less demand for stand-alone camera products.

The unparalleled growth of the smartphone sector and the mere idea of striving for a picture-perfect finish have become dominant, encouraging camera lens suppliers to inject funds into research and innovations. While most professionals prefer mirrorless and DSLR cameras, smartphone cameras come with new lens technology such as improved zooming, nominal weight, and space to cater to a more extensive retail consumer base.

Various factors must be considered carefully before investing in a camera system. What type of photography are you planning to do? The budget? How realistic about carrying a lot of equipment with you when you travel? Quantity of video you are planning to capture alongside your photography? These are all critical facts to consider before plunging into a system.
