The Power of Back Button focus.

When it comes to capturing stunning images of horses, every photographer seeks precision—a razor-sharp focus that showcases the grace and majesty of these magnificent creatures. In this article, I'm thrilled to share with you a game-changing technique that can elevate your equine photography to new heights: back button focus. With its ability to separate autofocus from the shutter button, back button focus empowers you to unleash your creativity, capturing every detail and movement with unparalleled clarity. So, let's dive into the world of back button focus and discover how it can transform your equine photography journey.


1. The Essence of Back Button Focus:

Imagine a dance between you and your camera, where autofocus becomes an independent partner. By default, the shutter button handles both focus and image capture, but with back button focus, you assign the autofocus function to a dedicated button on the back of your camera. It liberates you from the traditional autofocus-shutter button marriage, offering newfound control over focus and composition.


2. The Benefits of Back Button Focus:

  • Precision and Control: With back button focus, you have the power to decide precisely when and where to activate autofocus. Separating focus from the shutter button allows you to lock focus on the horse's eye or a specific point of interest, ensuring tack-sharp details even when recomposing the shot.

  • Continuous Focus for Dynamic Scenes: Horses are known for their graceful movements, and capturing their energy in sharp focus requires continuous autofocus. By keeping the dedicated autofocus button pressed, you engage the camera's continuous autofocus mode (AF-C or AI Servo), tracking the horse's motion flawlessly and seizing those fleeting moments of equestrian beauty.

  • Avoiding Accidental Refocusing: In fast-paced shooting situations, such as photographing horses in action, the last thing you want is your camera to refocus unintentionally when you half-press the shutter button. Back button focus eliminates this risk, allowing you to release and re-press the shutter button without affecting the focus you've carefully set.

  • Empowering Focus and Recompose: Sometimes, the most captivating compositions arise from positioning the subject off-center. With back button focus, you can achieve precise focus on the horse's eye or chosen focal point, and then comfortably recompose the shot without worrying about the camera refocusing as you press the shutter button. It streamlines your creative process, giving you the freedom to explore unique angles and perspectives.


3. Setting Up Back Button Focus:

While the specific steps may vary depending on your camera model, here's a general guide to help you set up back button focus:

  • Navigate to the camera's menu or custom settings.

  • Look for the autofocus settings or custom controls section.

  • Find the option to assign autofocus to a specific button, usually labeled AF-ON or AE-L/AF-L.

  • Select the desired button and activate it as the dedicated autofocus button.

  • If needed, disable autofocus activation on the half-press of the shutter button.

Remember, consulting your camera's manual or referring to online resources specific to your camera model can provide detailed instructions tailored to your equipment.


Back button focus is a powerful technique that unlocks new levels of precision and control in your equine photography. By separating autofocus from the shutter button, you gain the ability to precisely focus, track movement, and recompose your shots without the risk of accidental refocusing. With every click, you can capture the very essence of horses—their spirit, elegance, and strength—in razor-sharp detail. So, embrace the magic of back button focus, and let your equine images come alive with the beauty that only true precision can deliver.
