The 18-35mm F1.8 is a lens that lets APS-C cameras match the depth-of-field and low-light performance of a full-frame camera with a 27-52mm F2.8 zoom, obviating the need to upgrade, perhaps. On top of this, itâs made a 50-100mm F1.8, letting APS-C match a full-framer with a 75-150mm F2.8. Again, this lets an enthusiast who likes to dabble in
The answer is yes! You can use APS-C lenses on a full frame Canon camera, but there are a few things to keep in mind. First, using an APS-C lens on a full frame camera will result in a cropped image. This means that the edges of your image will be cut off.
One major difference is that a FF camera produces a depth of field that's around 1.3 stops shallower than an APS-C camera for the same subject & framing.This is most important when you have the aperture as wide as possible, e.g. for portraiture.
Photographer Manny Ortiz gives you a side-by-side comparison between the APS-C Sony a6000 and the full frame Sony a7 II for portrait photography so you can see the difference for yourself.
Hereâs the main advantage of mounting APS-C lenses on full-frame cameras: You can take advantage of smaller, cheaper APS-C lenses offered by manufacturers. These are often high-quality, but they cost much less than their full-frame equivalents. For instance, Nikon users often mount the (APS-C mount) 35mm f/1.8 lens on full-frame bodies. For whatever angle-of-view you see on your APS-C camera with a particular focal length lens (APS-C or FF), if you want the same angle-of-view using a FF camera you need to multiply the focal length of the lens you're using on your APS-C camera by 1.5X. 18mm on APS-C is the same AoV as 27mm on FF, so get a 28mm lens. 24mm on APS-C is the same hOLgm.
