Unless I missed something, somewhere, 'EF' is the naming used for Canon lenses (previously FD). Canon camera's (since the 80's I think) have been know as EOS ***

There might be alternate replacement for the mercury battery. Check out those 2nd hand camera shop. They still sell battery for those classics.

Hey I need these too. I have a Canon EF with a 50mm f/1.4 FD lens that still amazes me with the lens performance.:thumbsup:

For people who are interested to know... The EF has a voltage regulator, it takes 1.5V 625 batteries. Some are Silver Oxide some Maganese Oxide... doesn't matter. :)

You better hope your camera's voltage regulator still works... haha... :bsmilie: anyway i just heard that the difference in voltage gives slightly off in metering. I think u gotta experience it 1st hand :) ... everyone keep safe a distance! :bsmilie:

Hey,

one of my favourite camera of all time. I used to own 2 samples, but they had high battery drain rate (about a set of battery for 3 hrs)
So I left with both the old and new F-1.

There is a battery adapter that allows you to use the more regular batteries. As P&G photo B1- @ adelphi.


Happy shooting.

The 1.4V Zinc-Air batteries used for hearing aids will last for 3mths only once in contact with air. If the silver oxide can be found then they will last long.

Remember to switch off the camera if not using or else whichever batteries will only last only abt 4 days!!:sweat:

Adapter can also be used can also buy them(x2) but i've found a way to DIY them. But thanks for the info on the location. Will be helpful for CSer!! :thumbsup:

Wow, fellow EF users.. amazing.... Your EF will need 2 PX625 Mercury batteries, someone mentioned can still find it at some Sim Lim shop. There are supposed to be alkaline alternatives but these are 1.5V as opposed to the 1.35V of the mercury cells so your metering may be affected, or worse overload the metering circuit.

The EF needs the batteries only for metering and shutter exposures from 1 - 30 secs. From 1/2 to 1/1000 sec, it's mechanical shutter so no batts required. Yup, 30 secs to 1/1000 in a 1970s camera!! It's a solid camera with all the pro features of the F1 but no motordrive option.
