|More general information on the Minolta A2.
This thread shows a home made remote shutter and focus switch unit. Another person has made an IR remote. After reading about these I have made a similar device based on the receiver I extracted from a small radio controller car.
A rather nice commercial radio remote (the ZS-2) is made by Zap-Shot (reviewed here), but it does not appear to be compatibile with the A2 (though it might be with a cable adapter plug...). Still, its about $100 more than my ugly hack.
The key thing to look for is a remote controlled toy that can execute two control channels at the same time, which is probably pretty common since most of these will allow you to steer at the same time as you are accelerating or breaking. The reason for the two control chanels is then you can send a command on one to initiate the focus lock; and while locking the focus, you can send a command on the other to activate the shutter.
