Hello, my first post. I have asked this question on other forums but have not had an answer so far. I have just bought a GF-1 and need a flash for macro photography of insects. The flash must be capable of High Speed Synch or FP. I am not worried about oodles of power, wireless capability, bounce or swivel etc. Just the ability to synch at higher shutter speed than1/160. I was using a Canon G12 with the most basic flash, the 220Ex which had HSS capability, and that was fine for what I wanted to achieve. I guess what I am really asking is which is the smallest and cheapest flash with HSS capability that I can use with the GF-1.
