The Meike MK-320 is a compact hot-shoe flash featuring TTL functions and tilt/spin capability. It runs off of two AA batteries. This flash is also known as the Neewer NW320.
When I first mounted the flash on my camera I thought it was broken because the TTL function was not exposing correctly, however I realized that the camera didn’t initially recognize the flash so I had to pull it off and put it back on. Once I did that the camera recognized it fine. When you first put it on at any shoot though, you’ll need to pay attention to make sure the camera is properly recognizing it as it seems 1 in 6 times the camera didn’t see that a flash was mounted so the flash was just firing at an incorrect brightness.
Comparing this flash to the built in one on my D750, they’re about the same power, but where the benefit of this is in its diffusion and ability to bounce the flash off of the ceiling or walls. Because the flash face is larger, the light is smoother, and there’s less harsh reflections on skin. Included in the case is an additional diffuser that helps even more. I’m also fond of the LEDs that it includes for video mode, however, they don’t really illuminate all that much to be useful beyond a few feet. Exposure with TTL is good, perhaps a little bit on the bright side at times. Manual mode is easy to adjust functions and slave mode works fine.
Build quality seems reasonable at this pricepoint. All the buttons have a nice click to them and the plastic feels solid. With the 2 AA batteries inserted (you’ll need to provide your own), the flash has a decent weight to it. Not as much as a big flash mind you, but this is the type of device for someone who wants something more compact, so that’s a win.
This flash is small, so it is not a master of heat dissipation while repeating flash. Don’t fire too many in succession otherwise it will pause to cool down.
Overall it would make a better addition to a micro 4/3rds camera or a point and shoot than a standard full size DSLR. I wouldn’t personally use it in professional situations, but for the type of person who wants something to mess around with it’s cheap, compact and works decently once the camera recognizes it. My honest recommendation though: if you want to spend less and don’t mind a full size flash grab the Neewer VK750 II. It has more power, better TTL accuracy and a built-in zoom function (USA Link | Canada Link).
