I went with the gpio for my camera setup, mostly for convenience. If you do, remember to use a fuse or other overcurrent protection, as you will be bypassing Raspi's own self-resetting fuse, F3.

700mA is marginal for use with the camera module. I suggest 1A as a practical minimum, and higher if you are using other power-hungry peripherals at the same time. 700mA might do, if
it's a high quality supply that doesn't blink at power surges up to it's full rating, and you are using no other peripherals.

a bit on the low side, certainly outside the generic TTL 5V +/- 5% spec. Interesting that the system is stable with this supply; possibly the raspi/cam setup is more sensitive to voltage drop from power surges (which a higher current power supply should more easily swallow), than absolute voltage level. You might want to measure the voltage drop over F3 (located near the micro-USB connector, possibly on the bottom side of the PCB), to see if that is the cause of the low voltage. There will always be some voltage drop there of course, but 0.5V is a bit much. Powering through the gpio pins will avoid that drop, but bear in mind that there will be some (though hopefully lower) voltage drop over the fuse you use instead.
