    Canon Canonet QL17

    Hi Everyone,
    I have been getting back in to film over the past year and I have been lurking here recently.
    I have been interested in the Canon Canonet QL17 and have been watching them on ebay. Well today I acquired one from my Father-in-Law, that he said he had purchased in Japan in 1966. It appears to be the original model with a 45mm 1.7 lens. The camera seems to function properly (I will run a roll of film through it tomorrow to see what I get). I have been online all day researching it and most of the info I have come up with deals with the giii which seems to be very similar but with a few changes - mostly the lens (40mm vs 45mm) and the battery.
    I am looking for info on the battery as it seems very different from the type used in the giii. The battery door says 1.3v which I believe is the same as the giii and the battery from the camera doesn't have any info on it other then a patent #. I have posted some pictures here (sorry taken with my iphone) including the battery that I pulled out of the camera. Any help regarding the battery or any other information would be greatly appreciated.
    Thanks in advance.
    Joe

    according to the photo, I think the battery you have is LR-50 or PX-1. But the manual said it needs 625 or PX-13. Of course any of these battery would have wrong voltage and might cause wrong exposure.

    Some of the modern 1.5v batteries are, LR-50...PX-1A...A1PX.
    Please note: 1.5 volt batteries will not provide accurate metering.

    Keep in mind that you don't need a battery for this camera. I have never put a battery in mine and have been using it for years.
    f/22 and be there.

    If the battery is slightly different voltage than needed than act accordling.

    You can use a battery adapter, like that available fro Gossen and others for voltage reduction from 1.5 to 1.3. It is a tight squeeze but they fit into a Canonet.

    I think the OP may have a validly odd battery question he's asking.

    If the battery in his picture came from that Canonet QL17, what is it?

    It's not a PX625 format. It's much too tall for that. (I have a QL17 GIII and a freezer full of 625 mercury cells.) But references I've looked at, including Canon's historical archives, says 1.3-volt (MP) mercury. And he says the compartment door reads 1.3-volts.

    The only form factor I could find that matched that voltage, used to be available in mercury, and looked similar was a PX640. But even that seems just a bit shorter. And nowhere could I find a reference to 640s in Canonets.

    There is the PX27 format, but I believe the voltage is incorrect (5.6-volts in the original mercury version), even though it closely resembles the photo.

    So what is that battery?

    (Regarding camera model, I also note that his lens collar levers are significantly different from other QL17s.)

    Thanks for all the responses. I have been looking into the various battery options mentioned in this thread. For the time being I am shooting with an external light meter.
    Regarding the differences Ken mentioned - is it possible that they exist because the camera was purchased in 1966 in Japan and that there may have been a slightly different model released to the US and Europe?

    That battery looks exactly like a PX-640 -- a 1.35v packaging of two mercury cells. I don't think it was ever intended for a Canonet but iof it fit it may have actually worked.

    Re: Canon Canonet QL17

    I've been using PX625A batteries for many years with no issues.
