After a friend had become the i40 bought for Micro Four Thirds and kindly made available for a test on my Olympus OMD 5, I was thrilled. Very compact and extremely powerful for its size. (5 Stars) As I was still looking for a flash for my RX10 and RX100II, have you bought this in the photo dealer I trust. Unfortunately, he only worked sporadically in both cameras and resulted in 90% of the shots to incorrect exposures. So back to the dealer, who ordered a new one for me immediately. This was immediately tested in the store and also was not working.
Conclusion: Super Flash, but does not (yet) with Sony.
