MEIKE – MK420 – TTL HSS 2.4GHz Lithium-ion Speedlite for SONY Announced



Chinese flash and accessory manufacturer Meike have announced development of the MK420 Speedlite, a compact TTL and HSS enabled 2.4GHz radio flash for the Sony Alpha system, set to be available in June 2016.

The MK420 will feature both radio Master and Slave modes, providing TTL, Remote Manual, and High Speed Sync to 1/8000 shutter speeds.

A 2 watt LED light is also provided for focus assist and video use.




What really sets the MK420 apart though, is the option of using either an 8.4 volt Lithium-ion battery, or 2 regular AA batteries (mounted in a provided cartridge) to power the flash.

Use of a compact, though high capacity, Lithium-ion battery allows the MK420 to remain small in size and weight, for use with popular Sony mirrorless cameras. While still providing HSS, and a decent Guide Number or 42 meters (ISO 100).

    Glad to see more Li-ion flash units.
    I am also happy to see more options for our Sony friends.

    I am not sure when we will see this thing though as it is clearly not in physical form yet.

      Hi Mark,

      I think Meike are further along with this than the images might suggest. They could be available as soon as May (2016).

    That control layout looks very similar to the newly announced sony radio transmitter.
