The PT-EP14 underwater case, developed specifically for the OM-D E-M1 Mark II, can resist water pressure up to depths of 60 metres. From its large dials and grip design to the clear field of view the pick-up viewfinder provides, the PT-EP14 was designed with comfortable operation as the first priority. The FL-LM3 flash, included with the OM-D E-M1 Mark II, fits inside the case and can be used for lighting subjects underwater. For increased flash power, two UFL-3 dedicated underwater flash units (separately available) can be attached and used. The bayonet style makes it easy to change the lens port and to shoot with a variety of lenses.
