[QUOTE="WayneF, post: 236650, member: 12496"] The internal flash will not trigger again if it has not recycled, and the Ready LED is not yet on. Hot shoe flashes will trigger again anytime, but if not yet recycled and Ready yet, the results will be poor (and dim). The flash is ready for operation only when the Ready LED is on. On a hot shoe flash, low power level (like say 1/32 power) can recycle fast, and should work at several frames per second. Some flash models have a repeating mode, to flash several times a second, maybe 20 times per second, but which is of course only imaginably possible at pretty low power level, so they can recycle each time, for each flash. To achieve low flash power (and fast recycle) for TTL, you need high ISO, or wide aperture, or close distance, or maybe some degree of all three. To give proper exposure, the flash needs to recycle for each flash. The Ready LED must be on. The internal flash is a tiny flash, and probably needs near maximum power for about anything, where a SB-700 is larger and more capable (the lower power level it uses for same job will recycle faster). Saying, the internal flash will have to operate at an even lower power level to recycle quickly. [/QUOTE]
