I have two Minolta SrT with a modification performed by a technician to make them work properly with ordinary 1.5V silver cells. Very nice and dandy, but you have to send the camera to a technician (this work was performed during a general CLA for both).

I am a satisfied customer of Frans de Gruijter and consider his solution to be the best overall one, being cheap and practical.

And by the way, welcome to APUG!
