Thanks to Degreef & Partner, Nissin distributor for France and Benelux, I could test the Nissin MF-18 ring flash for Sony.
1 Presentation
1.1 Introduction
The Nissin MF-18 (370 eur) is a ring flash to be used in macro. It exist since a long time for Nikon and Canon but Nissin has now released a version for Sony E count compatible with the Multi interface hotshoe
The only other one I know for Sony E mount is the Metz Mecablitz 15 MS-1 (290 euros) but that has less functionalities (no TTL, only 6 power steps, no graphical user interface) and its performances are less good : Flash lights are concentrated in small areas on the side and not well spread around the ring

1.3 Build quality & handling
The flash consist of 3 elements
a Commander unit to be placed on the hotshoe with a control panel and hosting the 4 AA batteries
an adapter that you screw on your lens
the ring flash itself (linked by a fixed cable to the commander unit) that has two curved and diffused flash tubes (labelled A & B), supplemented by LED modelling lamps (you plug it on the adapter)
The box is nicely made, it includes
the main unit and
a series of adapter : 52mm, 58mm, 62mm, 67mm, 72mm and 77mm. You can order 49mm, 55mm and 82mm if you need one of them.
A quick user guide printed on the box
Overall the build quality is very good
The hotshoe is all in metal as well as the (blue) screw
All items are perfectly adjusted
A door is hiding: a USB port for firmware upgrade , a Synchro X , and an external power supply port (Nissin PS 8 Ni-MH Battery Pack for Sony Camera).
For the Sony 90mm F2.8 macro you will need the 67mm adapter
2 Basic operations
2.1 Mounting the flash
Attach the controller on the hotshoe of the camera
Screw the adapter ring that is the same size as the filter size of the lens onto the front thread of the lens
Attach the flash head to the adapter: Press the release buttons on top and bottom of the flash head to insert the four mounting tabs on the inside of the flash head on the adapter ring.
