I just got my new PT-E05 housing for my E-520 and am working my way through the instruction manual. I don't have my UFL-2 strobes yet and am wondering, do the TTL cables described in the PT-E05 Instruction Manual come with the UFL-2? I couldn't find any information on line specifically dealing with the TTL cables. I know that the PTCB-E02 cables will attach the flash to the housing, but is there something else I have to do to get the TTL feature to work? I found a part number (UW FL-TTL PTCB-E01), but there doesn't seem to be a lot of info on line about the use of it and whether it must be purchased separately or comes with the flash units. Please advise.
