Whenever I use a cable release with my Canon EOS 90D the photos are out of focus, it seems like the camera doesn't autofocus (AF) with the remote? Jimmy Bradley, Cuxton

BRIAN SAYS... The cabled remote releases have a two stage button that replicates the shutter button on the camera. This means that half pressing the remote release should initiate AF. If you have the audible beeps turned on, and use One Shot AF you should hear a beep when focus locks. It's possible that the subject was not within the area covered by the AF points, so no focus was found. You could also have back button AF configured on your camera, which usually means you have stopped the shutter button half-press from initiating focus. If this is the case, you need to change the shutter button to start focus when half-pressed, or press the AF-ON button on the back of the camera before using I the remote release.

Can you give some tips for close-up photos of bugs? They don't stay still long enough for me to capture them! Megan Ilyas, Nantwich
