Is The Canon 70d A Full Frame Camera

two. Full-Frame vs. Ingather Sensors

Even if you're new to the globe of digital single-lens reflex (DSLR) photography, you've probably heard a comparison between full-frame and ingather sensors. It might not have meant much to you when purchasing your kickoff photographic camera, but it certainly ways a lot in regard to the utilize of lenses and your future lens purchases.

Full-Frame Sensors

A full-frame sensor is the same size equally a 35mm film frame—just recall of the film shot in many pre-digital cameras. Y'all can find full-frame sensors in Canon camera models such equally the 6D, the 5D (all versions), the 1D-X, and all of the older 1D-S models. For those photographers moving from flick SLR cameras (and many other types of cameras) to a DSLR, a full-frame sensor does not affect how you lot apply your lenses and run into your images, and y'all tin can more than likely use the same lenses, as long as they are designated every bit EF drinking glass. For many, a full-frame sensor is much desired for many reasons beyond how information technology correlates with the utilise of our lenses, particularly among portrait and landscape photographers and photojournalists.

Crop Sensors

A crop sensor shares the same rectangular perspective (often referred to as the 3:2 ratio) merely is considerably smaller. How much smaller? For Canon crop-sensor cameras, a bit more than than 50 percent smaller. At the time of writing, Canon makes only one size of crop sensor, known every bit an APS-C sensor (Figure one.5). These sensors can be institute in anything "beneath" the 5D lineup, such every bit the Rebel series, the 70D (and its previous iterations), and the 7D. Up until a few years agone, Catechism 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-Ten, at which bespeak the APS-H sensor disappeared from production.

Figure ane.v This epitome represents what yous would capture using the three unlike-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 scrap-tighter shot considering of its 1.3x crop. Even tighter is the APS-C sensor'due south crop (green stroke), offer a roughly 32mm perspective.

The size deviation for crop sensors is determined past 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 cistron of one.6x (the now-discontinued APS-H has a one.3x crop factor). The larger the crop factor, the smaller the sensor. For the ingather cistron to become relevant in this instance, you lot must multiply the focal length of the lens by 1.6 to determine the bodily focal perspective in which you are shooting. Sounds confusing, and it is unless yous see information technology for yourself!

Permit's say y'all are using a 50mm focal length on both a full-frame camera, such every bit the Catechism 6D, and on an APS-C crop-sensor camera, such equally the Catechism 70D. For the full-frame camera, which has a crop factor of 1x, the perspective provided when looking through and shooting with the 50mm focal length is really 50mm. Notwithstanding, for the 70D, we must multiply the focal length, 50mm, by the ingather factor, 1.6, to determine the visual perspective with which we're shooting: 80mm. Since the crop sensor chops a considerable amount of sensor away from a full-frame flake's perimeter, the area of the lens now used tin be equated to an 80mm lens on a full-frame sensor. If yous are using a ingather-sensor photographic camera, multiply any focal length by 1.6 (or i.3 if you have an APS-H camera), and you'll find out what the equivalent perspective is on a full-frame camera.

A crop sensor does not actually magnify the focal length of whatsoever lens. It simply crops the sides, top, and bottom of the lens's angle of view. Withal, crop-sensor cameras are a big hit with folks in the sports and wildlife photography arenas, because compared to a total-frame camera that packs the aforementioned resolution (megapixels) as a crop-sensor camera, the crop sensor provides a flake further "reach" when looking at two images of the same size. This is not magnification, only simply the result of two different-sized sensors of the same resolution being combined with the same focal length.

Putting Them in Perspective

Then, practically speaking, how does this affect you? Information technology really all depends on which camera you are using. If you are shooting with a full-frame Canon camera, the focal length of the lens with which yous are shooting is going to event in that truthful perspective. Notwithstanding, on a crop-sensor camera, the perspective you get when putting any lens on the camera is just not as "broad" every bit it would be on the former type of camera. There is zippo incorrect with a ingather-sensor photographic camera. They are more than affordable because of manufacturing costs, and many are built with the aforementioned structural quality equally their total-frame versions. However, the next time you read online that an ultra-wide image was shot with a Canon EF sixteen–35mm f/2.8L on a Canon 5D Mark III, y'all might consider looking into a Catechism EF-S 10–22mm f/3.v–4.5 for your Canon Insubordinate T5i. At 10mm with this latter philharmonic, you are actually achieving the 16mm perspective of the former's prototype.

Wait, nosotros're not done with this subject yet! To make it fifty-fifty more complicated, Canon makes a set of lenses that work exclusively with their APS-C crop-sensor cameras. Whereas all EF-marked lenses piece of work on both total-frame and crop-sensor cameras, EF-S lenses merely work on ingather-sensor cameras. The EF-S lenses are fewer in number, but Catechism tries to accommodate crop-sensor camera owners by offering equivalents to some of the most popular EF lenses (such as the previous case). Typically, EF-S lenses are more affordable than their EF counterparts, but if yous are thinking about upgrading your camera body from a crop-sensor to full-frame sensor unit of measurement, y'all might hold out for EF glass instead of purchasing a lens that might exist useless in the most future. This is one of the deficiencies of moving to a full-frame sensor photographic camera system: Some, if not all, lenses might also demand to exist updated (or upgraded) to fit the new camera. Usually, photographers see this every bit a valuable transition from one organisation to the other, but it does come at a premium.
