When you come to display an image to fill a computer screen or a print, the result from the full-frame sensor is shown above. The field-of-view is narrower, but nothing else changes. The end result is a smaller area captured, but exactly the same as the central area of the full frame image. An APS-C camera only records a part of the full image (as shown by the white box on the central image). A full-frame camera captures the full image. The original shot was taken with an EF 400mm lens. The focal length might not change, but what does change is the field-of-view. Use the same lens on a full frame camera and an APS-C camera, and you end up with results like those below. It doesn’t.įACT: Focal length is a characteristic of the lens and is not affected by the camera or sensor size. There is a lot of confusion about crop factors, extended reach and telephoto effects when using lenses on APS-C cameras.įirst, let’s dispel the myth that the focal length of a lens changes when switched between a full-frame camera and an APS-C camera. So what does this all mean for your photography? ![]() Crop refers to the fact that the image you get with the smaller sensor is a cropped part of the image obtained with the full frame sensor. The main reason for the introduction of the smaller sensor was cost – full frame sensors are expensive. Then, in 2000, along came a camera with an APS-C 'crop' sensor – the EOS D30. EF lenses, like the FD lens system that went before, gave full coverage to 35mm EOS film cameras, then subsequently full-frame – 36 x 24mm sensor – digital cameras. The EF lens mount was introduced in the same year that the EOS was announced – 1987. Terms like ‘crop factor’, 'extra reach’ and ‘equivalent focal length’ just aren’t helpful. This is exactly what happened – as far as we’re concerned – when Canon introduced the EF-S lens mount. Which do you shoot, and why? Are you shooting work where it doesn’t make a difference which you have? Do you find the advantages of crop more useful to you than those of full frame? Or is even full frame too small for you? Let us know in the comments.Sometimes when an attempt is made to simplify or explain a term or reference point, it can end up complicating the situation. Whether I shoot crop, full frame or medium format, I usually want more depth of field, not less. People like Manny and others make it look amazing, but it’s not for me. Personally, I don’t do the shallow depth of field thing. Generally speaking, the glass you use is often far more important than the size of the sensor. If you like the full frame look and frequently like to shoot with a shallow depth of field, then get full frame. It’s all just personal preference, so study images and see which you prefer the look of. It’s not a question of one being “better” than the other, though, they’re just different. It’s one of those debates that’s never going to go away. Of course, you can still do it with crop sensor bodies and super fast glass, but it’s easier with a full frame. Throwing the background out of focus removes distractions and draws attention to your subject. Getting in close again, they pop right back up. It’s still there, but you don’t notice it as much unless you zoom in or print big. On other shots, the difference isn’t quite so obvious as you start to move away from your subject. This softness is one of the main reasons photographers choose to go full frame. The full frame is noticeably softer in the out of focus areas. The difference between the two is immediately apparent.
