The term crop sensor or full frame refers solely to the size of the imaging sensor inside a camera.
35mm vs full frame camera.
Full frame cameras have better high iso performance and more megapixels.
Any digital sensor of this size is regarded as a full frame.
Full frame cameras have a larger 35mm sensor compared to crop sensor cameras.
The first dslrs had cropped sensors and would render different fields of view.
Full frame digital cameras use a sensor that s equivalent in size to 35mm film 36 x 24mm and is the largest consumer format you can buy without moving up into the specialized realm of medium.
A full frame sensor is the same size as a piece of 35mm film which was and still is the most widely used type of film in analog cameras.
That means it is great for situations where you want to include more of the environment in the frame or you need to be close to the action.
If you mount the same lens to a camera with a full frame sensor vs one with a super 35 sensor the super 35 camera will give you an image that is 1 5x optically zoomed in.
Since the beginning of the 20th century the 35mm film format has been the standard.
But crop sensor cameras increase your effective focal length which is often useful for wildlife and bird photographers.
The more popular aps c sensor size found in most dslrs and mirrorless cameras.
The full frame sensor is based on film photography.
A full frame camera uses a sensor that s the same size as a single frame of traditional 35mm film measuring 36 x 24mm.
This has several practical effects.
The size of a 35mm frame in film photography is 36 mm 24 mm.
If you have a full frame camera then as i said above a 35mm is going to allow you to fit more in the frame than you can see with the naked eye.
A 24mm focal length lens will have the equivalency of 36mm.
Portrait or macro photographers however might find this very advantageous.
And the 35mm lens will give you much more depth of field because of its shorter focal length.
The term full frame comes from the early days of dslrs when the only lenses available were 35mm film camera lenses.
