The term ‘full frame’ means that the digital sensor in the camera is same as the old strip of 35 mm film frame. This increased surface area lets you capture pictures with high resolution, with enhanced color and detail. Majority of digital cameras use less 35 mm frame.
The sensor does not allow any changes to be made on the the focal length, it remains the same. The sensors on full frame cameras are wider and help to take sharper photos with dynamic range. The full frame camera sensors have larger pixels, which contributes to higher image quality. It is more preferred in wide-angle photography like landscape or architectural photography. The sensor design result in lower noise levels at high ISO and a greater range for captured images. Large aperture may put in the background out of focus and small aperture may force you to use shutter speed. Turning your ISO or using a tripod will prevent camera shake.
Other features of a full frame camera are-
Full frame cameras offer higher dynamic range, which means it has the ability to capture the highlights and shadows in detail.
Pixel density is lower in full frame sensors. This means that the pixels are larger. As it has more megapixels, the images can be manufactured so as to get larger prints and larger images.
It is useful with wide-angle perspective control or tilt/shift lenses used for architectural photography.
Some full frame DSLR’s (digital single-lens reflex cameras) are intended mainly for professional photographers. It has more features, rugged construction, increased mass result and larger dimensions when compared to the typical consumer grade DSLR’s.
Tripods and monopods are used to support the weight and maintain stability of the camera and lens. It prevents shaky pictures and helps to take sharper photos. Telephoto lenses work best when photos are taken using monopod or tripod.
