Re: Best M42 Camera?

I don't know, I've only had experience with models from the Spotmatic II 
on.  They could, but I don't know when Pentax started using the bridge 
circuitry for their meters.

Do you mean early Spotmatics would not give accurate metering with a

Spotmatics were originally designed to use a single 1.35 volt 625 or 
PX13(?) mercury cell.  Later models were designed to give correct 
meter readings with 1.5 volt replacements as well.
