When reviewing images in playback mode on the EOS 5D Mark IV, you can select various methods of magnification. One popular one is to zoom to ‘Actual Size’ (from selected point) which shows you a 100 percent view at your active focus point. This is a very quick way to check critical sharpness. If you set this and then zoom in, but find the camera is zooming to the centre of the image, check which AF setting you are using – in :-)+tracking or FlexiZone – Single the camera will always zoom to the middle of the frame rather than the active AF point. It is also worth checking whether you have Distortion Correction enabled as this will also cause the camera to zoom to the middle of the image.
