Re: Not that I'm aware of.

It is an implementation of two separate functions odf the camera: locking of the AF distance, and using focus priority to dictate the release of the shutter.

It basicallyworks in AF-s or AF-C, but you need to focus priority as prefered option in A1 and A2.

First you decouple the the AF fucntion fro mthe release button. This is done by assigning the AF-on button as the only button to achieve AF. The shutter button is only used to relse the shutter

Than AF is actived using he AF-on button at an object with a given distance. You than point set the camera to scene where no object yet is in focus at that given distance.
As long as the camera does not refocus ( do not touch AF-on) and you keep the shutter button pressed (wired or wireless is best), any object that appears in front of the camera at the distance you focussed on will be considered as 'in focus' and the shutter will be released.

Very handy if you know where action is going to be, e.g. catching bees or humming birds, anything to do with macro, or in sports. The good thing of this method is that you can put the camera on tripod or monopod without having to touch it when you a use cable or wireless release.
