Q: 10. I currently have a YS-03 strobe and am looking to add a second strobe, possibly the YS-01. Do you know if I can link the two strobes so that the strength of the YS-03 flash is controlled by the YS-01 strobe in manual mode?

A: The YS-03 is an auto only strobe, and uses a pre-flash. So the YS-03 exposure is set by the camera's built-in flash. Since the YS-01 does not use the pre-flash in manual mode it will not fire. To use the YS-03 and the YS-01 together you have to set the YS-01 on TTL, not manual. It is best to use two YS-03, or even better to use two YS-01.
