Could someone explain the difference between the YN-560 and the YN-568EX flashes?
I've looked online and am unable to figure out why the YN-568 is nearly double the cost ($72 vs $137).
EDIT: I've looked on B&H and it appears as though the YN-568 has TTL where the YN-560 doesn't but the YN-560 has wireless and the YN-568 does not. It still doesn't seem to justify a double in price.
