For people who have a camera
that uses a 1.35 Volt Mercury battery.
Like the Minolta SRT, Olympus OM-1, Canon FT, or Canon F-1 or many more
Mercury 1.35 Volt
batteries are no longer
available in the US, but many are selling a Alkaline so called
replacement, which is 1.5 Volts and will change the meter reading up
to two stops. The problem with Alkaline is the voltage changes as the
battery gets older. With some cameras like Minolta SRTs and Olympus
OM-1, a diode and adaptor can be installed so you can use a Silver
Oxide 1.5 volt battery.
I think the
best thing is to buy a MR-9 adaptor sold by C.R.I.S This will
last indefinitely and can be exchanged from camera to camera.
Here is a Link to C. R. I. S.
