Question: What is a full frame camera as opposed to a crop sensor camera !?
Best Answer - Chosen by Asker:

The Canon 5D and most of the 1D series are full frame cameras!. also most of your film cameras are full frame, with the exception of APS cameras!.

Take a film camera (if you have one, doesn't even have to be a Canon) and your EOS 1000 and remove the lenses!. Look at the mirrors side by side!. The mirror is pretty close to the same size as the sensor/film!. The film camera will be bigger!. Full frame refers to the size of what the film was on 35mm cameras!. It's a common standard that most people know!.

Now, your probably scratching your head asking "why bother!?"!. When digital sensors were first made there were problems with heat and the amount of energy they used and cost and other things as well!. So they went to a smaller standard, the APS size!. This size stuck for quite a while and is still being developped!. For example the new Canon 50D still uses it while the 5D that's been out for quite a while uses full frame!.

Is it something to worry about!? Not at all!. It just means that your lenses are a little more telephoto than the same lens on a full frame/35mm camera!. If you aren't used to 35mm then ignore it and just shoot!. What you see in the viewfinder is what you get!.

The EOS 1000 (refering to your earlier questions) is an APS-C sensor!. If you multiply your lens' focal lenght by 1!.6 that's the "effective" focal length in full frame terms!. A 50mm lens on your EOS 1000 acts like an 80mm lens on a full frame camera in terms of field of view!. Since your sensor is smaller than full frame your essentially cropping the image, you then print that image and one from a full frame camera both at 4x6 and it will appear like your more telephoto on the crop frame camera!.Www@QuestionHome@Com

I don't know why anyone would call the smaller sensor a "crop sensor!." There is no cropping down!. The lenses are designed to match with the sensor and if you were to shoot a picture with a full frame and a smaller sensor, you would get the same picture!. The difference would be that the area that you have to work with would be larger which would work like the difference between 35mm film and a 67 film camera, you can simply blow it up more!.

With a full frame camera, you have the same field of view as you would with a 35mm SLR camera!. It's not narrowed!. As a result, there's no crop factor multiplication factors!. For example, the Nikon d80 has a cropped frame sensor, and if you put a 400mm prime lens on it, it becomes a 600mm lens!. However, on a Nikon D3 ( Full Frame ) It would remain a 400mm lens!. And, the same applies with any other kind of lens!.

Look at that image, it compared a full frame camera to that of a Nikon DX body ( cropped frame ) Full frame doesn't have anything to do with the quality of the pictures though!. Www@QuestionHome@Com

A "full frame" camera has a sensor that is a full 24x36mm in size - the same size as a frame of 35mm film!. A crop sensor camera, as you call it, uses a smaller sensor!. It's as if you're cropping the image!. Most of these are approximately 2/3 the size of a full frame (a!.k!.a!. APS-C, after the old Advance Photo System film and it's size)!. The notable exception is Olympus, which has a 1/2 frame size!.
