A new article, this time explaining what Back-Button Focus is....
Below is an excerpt:
" Critical focus is one of the most crucial elements we attribute to a good photograph. This is especially true in my field of nature and wildlife photography where the accuracy of the focus will usually make or break an otherwise good photograph. A basic understanding of a cameras focusing system is fundamental at the outset of our photographic journey, but I often find that a more in-depth mastery of the camera’s focusing capabilities often takes a backseat while we improve other photographic aspects. Part of the reason for this is that it is effortless these days to pick up a camera and take sharp images with the default focus settings and issues only begin to arise when our subjects become more complicated. Whether it is a model’s eye in portraiture or the beak of a bird-in-flight, proper focus forms an essential part of the storytelling mechanism of photography. The key to sharp images starts with a fundamental understanding of your cameras focusing system and settings, which is why it is important to understand what back-button focus is and how you can take advantage of it in your photography."
