Excerpt: I added batteries as per the instruction and used this flash on a non profit event. The flash unit got very hot so I could not use the flash and returned this back to B&H for an exchange. B&H was very professional on getting me another new unit right away.
Excerpt: Not too small, not to big, but just right. Just purchased the Sony A7II. I wanted a lighter camera for some extensive travel I have planned. This flash works wonderfully to keep the weight and size down while still giving me all the features I've come to expect of a speed light.
Excerpt: Mounted on a Fujifilm X-T1, very versatile in that you can flash straight-on, bounce, use the included bounce white card, flip over the wide-angle cover, or mount the plastic 'soft-box' dome, plus manually zoom the flash head, or let it use the intelligence from the camera to zoom appropriately.
Excerpt: I have used this flash for Canon, Nikon, m43, and Fuji formats. It performs flawlessly and is easly handled. Great match for a D750 and fully iTTL and FP compatible ans is well-balanced on the top of the camera.
Excerpt: This flash is Perfect for my Sony a6000 camera. It is small enough that it doesn't unbalance the camera, yet is quite powerful. I started off with the Nissin di700 - I was all jazzed up about the radio controlled slaves.
Excerpt: I've only been using it for 1 week, my initial impressions ok. One of the things I have done very successfully in the studio is use the i40 to wirelessly trigger other branded much bigger speed lights and studio strobes. It worked very well in that situation.
