Hi thanks for your help, the battery is brand new and the contacts are clean, I gave it to the photography technician in University who could not work out what was wrong...maybe a loose connection...I contacted pentax for advice but they haven't got back to me yet.
I bought mine before x-mas, I'm thinking it could be me not setting it properly and it would still be an excellent camera with a seperate light reading but I bought this camera so I won't have to use one ...AND NOW IT'S NOT WORKING GGGRRRR...!
Thanks anyway.

Hello all!

I just got a well reputated medium format, the Pentax 67 off ebay, it included a prism with light meter which seemed to be working fine when I first received the camera.
I do not have a manual and the light meter within the prism now seems to only be working when he wants and not when I want...Grrrrr...! I thaught the ebay seller got rid of it cause he knew something was dodgy but maybe I am not doing the right maneuver, help please!
Thanks
