Understand your camera's manual focus mode and practice focusing on stationary objects before attempting to capture fast-moving hummingbirds.
Set your camera to single-point focus mode to ensure precision when focusing on the hummingbird's eye, which is crucial for sharp images.
Use focus peaking if available on your camera to highlight in-focus areas, helping you achieve sharpness in your hummingbird images.
Adjust your aperture to achieve the desired depth of field, balancing sharpness on the hummingbird with a pleasing background blur.
Consider using a tripod or monopod to stabilize your camera and lens, especially in situations where you need to maintain focus for an extended period.
Practice patience and be prepared to take multiple shots to increase your chances of capturing a perfectly sharp image of a hummingbird in action.
