The composition is to that in the previous example where the 5D Mk II with 300mm lens filled a similar amount of the frame. Lastly, we attach the 600D to the lens, and now the eagle is filling the frame (red lines), with little space around the subject. Like we've zoomed in tighter (blue rectangle). Switch to the 1D Mk III body, and it looks WhenĪttached to the 5D Mk II body, notice how much space there is around the eagle (black rectangle). Okay, let's take a second scenario, with the same eagle (amazing how it holds its pose!), but this time using a 200mm lens. Now attach a Canon 600D (Rebel T3i) to the lens and even more of the eagle falls outside the sensor (red rectangle), cropping off significant bits of the bird. Sensor, and parts of the bird overlap or fall outside the edges of the sensor (blue rectangle). You were to switch bodies and attach a Canon 1D Mark III (with APS-H sensor) to the lens, the image of the eagle is now too big for the In this example - using a 300mm Canon EF lens on a Canon 5D Mark II body - note how the eagle fits snugly into the area of the full-frame sensor (black lines). See diagram below, where the black rectangle represents a full-frame sensor (36 x 24mm in size), the blue rectangle represents anĪPS-H sensor (28.5 x 19mm in size), and the red rectangle represents an APS-C sensor (22.5 x 15mm in size) (Note: sensor sizes not to scale). So a portion of the image, along the top, bottom, and sides, will "spill" over the edges of the sensor and be lost. However, if you replace the full-size sensor with a smaller one (sub full-frame), some of the image will "overflow" as the size of the image will be bigger If the same lens is attached to a full-frame digital camera, the image will similarly cover the area of the sensor. Lenses made for traditional 35mm SLR cameras are designed so that the circular image cast by the lens fully covers the rectangular area of theįilm.

APS-C sensor - smallest of the three (22.5 x 15mm) found on Canon Digital RebelĬameras (like the 450D, 500D, 550D, 600D, 650D, 700D), the prosumer Canon **D models (30D, 40D, 50D, 60D), plus the Canon 7D.APS-H sensor - slightly smaller than full-frame (28.7mm x 19.1mm) found only onĬanon EOS 1D digital cameras (now discontinued).
