Seeing everything vs seeing some of it. Confused huh, so was I. When talking about DSLR's you will hear people say I have a full frame and I will never go back to a crop sensor camera again. What they are in fact referring to is the size of the sensor of the camera. If you want to get really number specific, older film cameras had a film size of 35mm so a full frame camera's sensor had basically the same size as this, a crop sensor camera would be less. How does this translate to you? Well the easiest way is to show you. If you look at the photograph below you will see a red square, basically if you were using a crop sensor camera (such as the Canon T3i Rebel) that is the image you would actually see, whereas if you were using a full frame camera such as the Canon 5d MkIII your image would be the entire photo.
The full frame camera simply gives you more image to work with. Now do not disown a crop sensor camera simply because of that reason. One of the major advantages of crop sensor DSLR's is that they are usually cheaper, so if you don't have the cash to splurge on that full frame you can get a crop sensor. Also the other advantage is the "crop factor".
Nikon cameras are either full frame (FX) or crop sensor 1.5x (DX) with a crop factor of 1.5x
Canon cameras are either full frame or crop sensor with a crop factor of 1.3x or 1.6x
The crop factor comes in very handy for telephoto lenses. Say for example you have a 5dMkIII with a 300mm lens attached. That 300mm focal length is only 300mm, however if you were to attach that to a crop sensor camera with a crop factor of 1.6x then you effectively have a 480mm lens!!. More lens for your money, sadly though it works the same way for smaller lenses so that 35mm lens would really be 56mm on a crop sensor camera which makes getting wider angle shots a bit harder.
