The MK-R200 is a tiny and strictly wireless macro flash triggered by a 2.4Ghz signal from the MK-GT620.
The MK-R200 is very similar to the Nikon SB-R200 but at a fraction of the price. It uses 2xAAA each and communicates using radio frequency signals so no line of sight is required.
The MK-R200 can be only be triggered by its corresponding MK-GT620 version. Please make sure that you are purchasing the correct version to ensure compatibility.
Note that all current stock are of the new models MK-GT620NII MK-GT620CII MK-GT620SII. They are not compatible with the old versions.
Also sold as a set in MK-MT24.
MK-R200NII is no longer in stock.
