The World According to Your AF Sensor
Extract from thread initiated by Rainer Hönle (Nightshot) on


It is not easy to get access to the image data generated by the AF sensor, so I thought, if you remove the AF chip from the AF module and substitute it with your own sensor then you can capture that image at will. The experiment was performed with the AF module of a 7D, but the principles outlined here are applicable to other cameras as well, except the AF point layout will vary.
