Up until a few years ago, Canon also manufactured another, larger crop sensor known as an APS-H sensor. These sensors can be found in anything “below” the 5D lineup, such as the Rebel series, the 70D (and its previous iterations), and the 7D. At the time of writing, Canon makes only one size of crop sensor, known as an APS-C sensor ( Figure 1.5). How much smaller? For Canon crop-sensor cameras, a bit more than 50 percent smaller. Crop SensorsĪ crop sensor shares the same rectangular perspective (often referred to as the 3:2 ratio) but is considerably smaller. For many, a full-frame sensor is much desired for many reasons beyond how it correlates with the use of our lenses, particularly among portrait and landscape photographers and photojournalists. For those photographers moving from film SLR cameras (and many other types of cameras) to a DSLR, a full-frame sensor does not affect how you use your lenses and see your images, and you can more than likely use the same lenses, as long as they are designated as EF glass. You can find full-frame sensors in Canon camera models such as the 6D, the 5D (all versions), the 1D-X, and all of the older 1D-S models. Full-Frame SensorsĪ full-frame sensor is the same size as a 35mm film frame-just think of the film shot in many pre-digital cameras. It might not have meant much to you when purchasing your first camera, but it certainly means a lot in regard to the use of lenses and your future lens purchases. Crop SensorsĮven if you’re new to the world of digital single-lens reflex (DSLR) photography, you’ve probably heard a comparison between full-frame and crop sensors.
