A full-frame sensor is the size of a 35mm film camera frame, which is 24mm x 36mm.
In digital photography, the term "full-frame" refers to a sensor size that mirrors the traditional 35mm film format. This is significant because it's used as a benchmark when comparing sensor sizes in digital cameras. Cameras with full-frame sensors are often preferred by professionals and serious enthusiasts due to their ability to capture more light, resulting in better image quality, especially in low-light conditions, and shallower depth of field.
Here's a breakdown:
- Dimensions: The sensor measures 24mm in height and 36mm in width.
- Relation to 35mm Film: It matches the size of a single frame on a standard 35mm film roll.
- Benefits:
- Improved image quality, especially in low light.
- Wider dynamic range.
- Shallower depth of field capabilities.
- Less noise at higher ISO settings.
- Comparison to Crop Sensors: Sensors smaller than 24mm x 36mm are often referred to as "crop sensors" and introduce a "crop factor" which affects the field of view.
Therefore, when someone refers to a "full-frame" camera, they are highlighting the size of the image sensor, and its implications for image capture.
