The electronic viewfinder is one of the greatest advantages of mirrorless cameras, offering the ability to preview your exposure in real-time, leaving behind the days of miscalculated shots. However, as this informative video details, it can easily mislead you and cause you to mess up important photos.
Coming to you from Katelyn James, this helpful video details a subtle problem with real-time exposure previews in electronic viewfinders. The problem is that the exposure preview in an electronic viewfinder is correct in the sense that it shows you the relative brightness of the overall exposure, but not necessarily in the individual contributions of each exposure parameter. In other words, your shutter speed might be far too slow for the action at hand, and you might not even realize this because the total exposure is still correct. What is worse is that a lot of photographers check their shots less with a mirrorless camera because of the confidence they get from the exposure preview. So, while that real-time exposure preview can be tremendously useful and can help you stay more engaged with things like posing and composition, make sure you are checking the actual shots every once in a while to ensure the individual settings are where they should be. Check out the video above for the full rundown from James.
