YS-D1 / Z240 or another one fpr E-M1

Hi,

on the next week i will get my new housing for my Olympus E-M1, actually i use a RX100 with on flash, the INON D2000.

Im ponder about to by a second flash for my setup.

Which one are the best opnion? The Z240 or the YS-D1?

Is it nessesary for makro tho use 2 flashes?

It is not necessary to use 2 flashes for macro, but can be helpful. I uses 2 D1's on my housing and an off camera Z240 for a snoot when shooting macro. I find the controls on the D1 a bit more intuitive, and find them a bit more powerful than the Z240 for macro work. I use the Z240 for my snoot because it's modeling light works better with my Retra light shaping device snoot. Because you are already using the D2000, it may be easier for you to stay with Inon. Both the D1 and Z240 are superior strobes.
