As the technology inside our cameras continues to advance, understanding and controlling all its new capabilities becomes a little more complicated. Between autofocus modes, points, zones, calibration, and the material components making it all function, there’s a lot going on that can potentially make you miss your shot. In this easy to follow video, Steve Perry from Backwoods Gallery shows us eight (sorry, not 99) common autofocus problems and solutions to make them work the way they should.
The video discusses several autofocus issues you may have been able to figure out yourself at some point, but also probably a few you didn’t realize affected autofocus performance. Perry goes over lens calibration, dirty autofocus points and how to properly clean them, how to make sure you are in the right autofocus mode, the inaccuracy of in-camera autofocus guides, how heat refraction can make autofocus difficult, how to clean dirty contacts on your lens and camera, mistakes that are due to poor shooting technique rather than autofocus error, and lastly how to shoot objects that inherently cause trouble for autofocus systems. As you can see there is a lot going on here, but Perry manages to touch on them all with enough explanation and demonstration that it is easy to understand.
Are there any extra tips for autofocus perfection you want to share? Let’s hear them in the comments below.
