The MF18 is a large circular ringlight for macro or fashion photography with Nikon DSLRs. Its two flash reflectors can be extended sideways to increase the light coverage and as well as offering TTL control it can act as master or slave gun in a multi-flash set-up. Two LED modelling lamps can be ratioed in line with the flash power setting. There is a large clear colour LCD control panel on the power unit, which also has a metal foot for durability. The display auto-rotates if the camera is turned sideways. External power packs can be used with the gun, and it's supplied with 58, 62, 67, 72 and 77mm adapter rings.
