DSLR Controller AFMA is an app made to assist Auto-Focus Micro-Adjustment calibration of your lenses on your Canon EOS bodies, based on the moiré method.
It is based on the code for DSLR Controller ( http://dslrcontroller.com/ ) and as such runs on the same devices and has the same connection capabilities. Of course, your camera must support Auto-Focus Micro-Adjustment for this to be useful at all.
It is currently in alpha stage. I'm releasing it in the currect state because I will be out of the country for a while, and I won't be able to finish it up further before I go. The manual ( http://dslrcontroller.com/afma/ ) seems long and daunting, but once you've used it once or twice, it really only takes a minute or so to set up.
You can play with it now for free. Fair warning, it wil probably transition to a (cheapish) paid product if it ends up being useful.
Read more in the quickly improvised manual which can be found on the DSLR Controller AFMA website ( http://dslrcontroller.com/afma/ )
