I bought this flash for my Panasonic LX100. Now I also use it with a Panasonic GX-7. Mirrorless cameras have been smaller than DSLR cameras, but the accessories haven't always followed. The i40 is smaller than I would have thought possible for a flash using 4 AA batteries.

Good flash but poor service from Nissin. The flash worked for 2 shoots for a total ofI purchased a flash and I have been bounced around between the distributor and Nissin. Neither want to assume the responsibility of repairing or replacing the flash.
