Found some old kit that my dad gave me years ago in my loft and wondered if it was worth integrating somehow into my OMD-E5 system,Theres an old lens which is branded either Topmon or Topman I haven't a clue about the brand at all but it seems in good condition, its a 135mm 2.8 manual focus prime with an adaptor ring. Theres also a Hoya 2 times converter both are Pentax k fit I believe as they fit on an old Chinon camera. Theres also a Chinon flash, I know not to put it directly on the hotshot as it might fry my camera but is there any other way which will be worth me utilising it in some way as ive never used flash before so haven't a clue lol, thanks for any advice
