Using old cameras can be troublesome dues to the use of old mercury cells ...that are now prohibed ! One solution is to use a suitable diode (see instruction). the assembly needs a DO35 package. I made several adapters : SR44 to PX625 : works well SR44 to PX675 : can be tricky/impossible to insert with the camera as the PX675 and the SR44 have the same size and the adapter add some thickness SR41 to PX675 : Haven't tested as I don't have SR41 ....but you have the source to adapt !The last image is a printed one with the diode in it. Juste be sure to put the diode in the right way in respect with the batteryPrint. Insert diode (thisone for exemple : http://fr.rs-online.com/web/p/diodes-de-redressement-et-schottky/2513025/?searchTerm=2513025&relevancy-data=636F3D3126696E3D4931384E525353746F636B4E756D6265724D504E266C753D656E266D6D3D6D61746368616C6C26706D3D5E5C647B367D247C5E5C647B377D247C5E5C647B31307D2426706F3D313426736E3D592673743D52535F53544F434B5F4E554D4245522677633D4E4F4E45267573743D3235313330323526) Insert in camera (right direction) Enjoy
