Full frame refers to a digital camera with a sensor the same size as a frame of 35m film. These are the high end professional level digitals. The more affordable models use smaller sensors of various sizes. These are called "crop sensor" cameras. My EOS50D for instance, uses an APS-C size sensor, which is roughly 2/3 the size of a full frame. Your sony also uses an APS-
C sensor.
Because of the smaller field of view these sensors have, the effective or perceived focal length is multiplied by a factor of 1.6. This means that you need to multiply the focal length by 1.6 in order to get what the 35mm equivalent would be. for instance 50mm is a fairly normal focal length on a 35mm frame, but on a crop sensor camera, it provides a slight telephoto field of view, about what an 80mm lens would on the 35mm film cam. Hope that makes sense.
Compact cameras have an even smaller sensor. |

"Full frame" is one of those manufacturer terms designed to make something seem like it is more than it is. It is sorta like when they say that a 100mm lens is a 160mm "equivalent" on a small sensor camera. It isn't and don't be fooled into thinking it is. Its really just a 100mm lens with the field of view of a 62mm lens. But sounds a lot better to call it a 160mm "equivalent".
"Full frame" is another made-up term by dSLR manufacturers to make a dSLR sound better than just a standard 35mm sensor size. 35mm is still considered small frame in the "real" photography world.
If you've always used small sensor cameras then the word "equivalent" describing lenses is totally meaningless to you but the term "full frame" takes on meaning because of the wider field of view it gives by comparison to what you are used to.
But if you are an old timer who predates dSLR cameras and move back to a 35mm sized sensored dSLR then it is just like going back home.

True... Was hitting up some film yesterday and god I miss the view finder of a "FF" 35mm camera. The 7D has a great VF as these things go but it's not FF and it's not the same but I have no way to describe it other then it's just more comfortable then the crops.... and maybe that is just for us old farts that got used to it in film bodies [I DON'T miss the single horizontal point AF though....]. |
