This way, you can see the hard edges of the original image through the filtered one. To achieve the effect shown in the second example of Figure 8-16, the Opacity value was reduced to 65 percent, making the blurred image slightly translucent. Press Ctrl+Shift+F ( z +Shift+F on the Mac) to bring up the Fade dialog box. The results are shown in the first example of Figure 8-16. Enter some unusually large value into the Radius option box ” say, 8.0 ” and press Enter or Return. If you only want to apply the effect to a portion of the image, feather the selection with a Radius in the neighborhood of 5 to 8 pixels.Ĭhoose Filter Blur Gaussian Blur. And remember, with an optional Canon Lens Mount Adapter EF-EOS R, this same range of wide- and ultra-wide lenses can be used on the new EOS RP mirrorless camera as well.Select a portion of the image if desired. Whether you shoot landscapes, interiors, or architecture - or just love the exaggerated look a wide-angle lens can deliver -a full-frame photographer can choose among a broad range of zoom and fixed focal length wide-angle lenses.

On the other hand, the EF lens series offers many wide-angle and ultra-wide angle lenses that produce exactly this coverage and “look” when mounted on a Canon full-frame DSLR or full-frame mirrorless camera. However, as of early 2019, only two lenses in Canon’s current EF-S lens line-up can deliver this performance. Special zoom lenses in the Canon EF-S lens line - available for Canon APS-C camera users - deliver a true ultra-wide angle view with the smaller-sensor cameras. Unfortunately, that same lens conversion factor also affects any wide-angle lens you attach. For example, a 200mm lens provides coverage equivalent to what a 320mm lens would provide on a full-frame camera. In other words, any lens you attach to an APS-C sensor camera “acts” like a longer lens, providing more of a telephoto effect.īecause any lens you attach to an APS-C sensor camera acts like a longer telephoto lens than its marked focal length would traditionally suggest, it can actually be a benefit for telephoto shooters. For example, fitted with a Canon EF series lens like the EF 50mm f/1.4 USM, the full-frame EOS 5D Mark IV camera will produce a true field of view, whereas the EOS 7D Mark II camera with an APS-C sensor has a 1.6x crop factor that effectively crops the field of view, producing effective lens coverage similar to what an 80mm lens would produce on a full-frame camera. To capture sprawling landscapes and towering skyscrapers, a full-frame camera lets you fit more of the scene into view than an APS-C crop sensor camera, when using the same lens. That’s because the APS-C sensor has less than 40 percent of the surface area of a full-frame sensor or a 35mm film frame. Although an APS-C sensor can produce photographs that rival the 35mm in terms of initial quality, the resulting images appear cropped in comparison to full-frame photos. The modern full-frame camera is based on the classic 35mm film frame, long deemed an industry standard for professionals and enthusiasts.Ĭompact digital cameras and early digital SLRs could not accommodate a sensor equivalent to the large 35mm film frame, so camera manufacturers developed smaller sensors. An APS-C sensor is significantly smaller overall than the 36x24mm dimensions of a full-frame sensor.

Camera sensors range in sizes, from sensors only a few millimeters across, commonly used in smartphones and point-and-shoot cameras to the larger APS-C crop sensor found in most entry- and mid-level DSLR and mirrorless cameras all the way up to the full-frame sensors found in many professional series camera models.ĪPS-C is an industry-wide term that describes digital image sensors roughly 22x15mm in size. The sensor size, as well as the number of pixels that fit onto the sensor, affects how much you see through your viewfinder. Through complex processing, the camera converts light into the image you see in your electronic viewfinder or on the LCD screen. Whether you’re taking selfies, getting quick snapshots, or capturing sweeping scenic vistas, the size of your camera’s image sensor has a major impact on what you see in your viewfinder and how you compose your photos.Įach pixel on a camera’s image sensor captures light in a scene. When it comes to digital camera sensors, size can matter.
