We have covered the majorly high-end Mamiya digital DSLR medium format cameras before here on SlashGear with one of the more recent offerings being the DM40 back in March. Mamiya and Phase One have announced a new accessory for the Mamiya 645DF cameras that offers fast flash synchronization for the line of cameras.
The new vertical grip is called the V-Grip Air and it offers flash sync speeds as high as 1/1600s. In addition to offering flash sync, the grip also extends the battery life of the camera while shooting thanks to an internal battery pack. The flash sync system works with most all Profoto flash systems and an optional receiver is available to allow the grip to work with other brands of flash systems.
The grip uses the same type of battery that is used in the Phase One and Leaf digital camera backs with the option to use standard AA batteries as a backup. The V-Grip Air for 645DF cameras sells for $1290 and the L-Bracket and hand strap package alone is $299 with both set for shipment in late September. That transceiver for other flash brands is available for $199.
