(This is likely in the wrong section but it is power related)

I just got my A75 (it rocks) and am trying to get some basic accessories on a budget. The Canon specific 4.3 volt ac to dc adapters are expensive but there are many affordable 4.5 volt adapters that have proper amps and the right connecter.

So, my question is this, has anyone tried one of these 4.5 volt adapters with the A75? Alternatively, is there a way to reduce the voltage by that ever-important .2 volts?

Thanks a bunch,

Mark

It should work without problem, but don't take my word. I don't have a Canon Ax. Never tried. I use a third party 6 v adapter for a 6 volt nominal camera need.

BTW:

A Germanium diode in series with the load will drop .2 volt.

A silicon diode (cheaper and very popular) in series will drop .7 volt ( 5 - .7 = 4.3 volt):-)

Found some more info about this over at Steve's.

It appears that there is some range in terms of voltage and the A70/75 can take arround 5v with no problems. Radioshack has an adapter that is 4.5v and 1600ma, ill try it out and post observations.
