SUMMARY
Autofocus technology has significantly improved, leading some to believe it eliminates the challenge of photography. However, even experienced photographers regularly miss focus. Factors such as shooting erratic subjects, using long lenses, shooting at wide apertures with shallow depth of field, and low light conditions can challenge even advanced AF systems. The hit rate depends on more than just algorithms, involving the lens, aperture, light, and subject behavior.
TAKEAWAYS
Autofocus systems are not infallible and misses still occur regularly.
Subject movement, lighting, lens choice, and aperture significantly impact focus accuracy.
Long lenses and wide apertures reduce depth of field, demanding precise focus.
Even advanced AF systems struggle with erratic subjects in challenging conditions.
