The different sensor sizes require some mathematical juggling to convert the fields of view of the lenses. But we’ll come back to this later in this article. Obviously, depending on the surface of the sensor and the number of photosites, these will be more or less large, which will have an impact on the image quality.

With the digital, these sensors have allowed to gain a lot of comfort, such as the possibility to increase ISO sensitivity where film cameras were more limited, to shoot photos AND videos, to retrieve digital files read directly by the camera or by a computer, etc… The sensor consists of a number of photosites which are sorts of light-sensitive cells which, to put it simply, correspond to the number of pixels. To put it simply, it is the sensitive surface that will capture (hence its name) the light sent by the lens.
Apsc sensor vs full frame full#
Although this format is a little less popular and avoids the APS-C/FF war (for Full Frame), it has some advantages and deserves its place in the hierarchy.īefore we start, let’s remind ourselves what a sensor is. Over the past 10 years or so, another format has made its appearance with some mirrorless cameras, the Micro 4/3. Before the introduction of mirrorless cameras, DSLRs were the kings in this field and mainly proposed two sensor sizes: APS-C and Full frame sensor. 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.When considering buying an advanced camera with interchangeable lenses, the choice of the camera sensor size is inevitable. 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.
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. 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. 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. Crop SensorsĪ crop sensor shares the same rectangular perspective (often referred to as the 3:2 ratio) but is considerably smaller.įor 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. How much smaller? For Canon crop-sensor cameras, a bit more than 50 percent smaller. At the time of writing, Canon makes only one size of crop sensor, known as an APS-C sensor ( Figure 1.5). 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. Up until a few years ago, Canon also manufactured another, larger crop sensor known as an APS-H sensor.
It was exclusively reserved for the 1D lineup until Canon introduced the 1D-X, at which point the APS-H sensor disappeared from production.įigure 1.5 This image represents what you would capture using the three different-sized Canon sensors. The red stroke represents a ull-frame shot made at 17mm.
When using the same lens, and APS-H sensor (purple stroke) captures a bit-tighter shot because of its 1.3x crop. Even tighter is the APS-C sensor’s crop (green stroke), offering a roughly 32mm perspective. The size difference for crop sensors is determined by the sensor’s crop factor.
This is where the sensor matters when it comes to lenses. A Canon APS-C crop sensor has a crop factor of 1.6x (the now-discontinued APS-H has a 1.3x crop factor). The larger the crop factor, the smaller the sensor. Sounds confusing, and it is unless you see it for yourself! For the crop factor to become relevant in this case, you must multiply the focal length of the lens by 1.6 to determine the actual focal perspective in which you are shooting. Let’s say you are using a 50mm focal length on both a full-frame camera, such as the Canon 6D, and on an APS-C crop-sensor camera, such as the Canon 70D.
