Yup, the original OM-3 and 4 had unacceptable, irreparable problems with battery drain, which is the main reason why my OM-3 sees less use than the OM-2. The only solution is to buy an OM3T/Ti or 4T/Ti which was not really an acceptable way of solving the problem seen from the user side, not then and not now. But at least the OM-4T/Ti stayed in production for 16 years (the original OM-4 was only made for 4 years), giving users a few years to cover the extra cost. I somehow doubt that any current digital camera will stay in production for 16 years
