Photography podcast #84 is based on a single comment by Richard from our forum where he mentions rear-button autofocus to aid in sharpness. This technique was developed by Canon about 20 years ago but I first heard of this technique on the MPB podcast (link in shownotes — thx for finding it for me Martin!) about two and a half years ago. Basically this technique REMOVES autofocusing from the shutter release button and assigns it to a button on the back of the camera. Especially when tracking a moving subject, this is a great technique and will likely get you more keepers. It will also STOP your autofocus from tracking things that you don’t want it to.
