PIC relays control

[Pic_User]

For the kind of current your looking at. I would use a n-channel FET. I dont really have any easy way of making a schematic for you but I will try and explain.

Take the HIGH from the pic and run it through a series resistor that will limit the current to about half the Imax of the PIC (about a 100 ohm should give you about 12mA off the top of my head) hook the resistor to the gate of the FET put the load (your camera) in the source circuit and ground the drain.
Hope I have helped....

5 V/100 Ohms = 50 mA
5 V/400 Ohms = 12.5 mA (half the Imax of the PIC)
