Canonet QL17 with LR44 battery?

[David Hughes]

davidnewtonguitars--Why are you bothering to use expensive Wein cells in your Spotmatic? The meter circuit is a Wheatstone bridge which works with any voltage. When the bridge is balanced, the meter reads zero because no current is flowing through the meter. With a no current condition, it doesn't matter what the voltage is.

I think the problem is that we have to know, or be told, about the bridge circuit being used. It doesn't get mentioned in the cameras' manuals and a lot of people would not expect it in a camera designed around mercury batteries, with their stable voltage...

It would be nice if there was a list of cameras with bridge circuits but I've yet to see one.

Regards, David

I've seen many posts, over the years, about the meter circuit in Spotmatics.

The QL17 and the QL17 GIII have the same battery chamber.

The o-ring works very well on both.

Ahh, mine must be a differnt type of QL17, maybe they just did a short run. Here is a photo I just found online: https://goo.gl/images/fkNDjP
I will try gluing what I have to plastic or something.

That's a Yashica Electro 35 not a Canon QL17.

I find it hard to believe that the OP has been referring to his Yashica Electro as a Canon QL17 this whole time...

OP seriously needs to post a photo of their battery compartment because this is all quite bizarre.

Oh, man. I just laughed out loud! "facepalm"

Go to home depot and get a very short section of tubing with appropriate inside and outside diameters for the battery and the camera, and fill one end with a wad of aluminum foil.

Oh yeah, curved edges but mine is not a Yashica, I would post a photo if I knew how, seems to be no upload feature. Just found it- too limited for my tablet. Its the same sort of thing.

To the last poster I thought of that before then thought of the big wide straws in 7/11. Will get it working somehow.

Although the developers said my photos turned out well with the Sunny 16 rule, so its not essential. I thought developing was printing 😀 so told them just to scan the 2 rolls and I will see in 2 days. I have an XA2 on the way as I don't like the ergonomics of the Canon so may get rid of it anyway.

What is going on in here?!? Lol

Seriously though. If you actually have a canonet ql17 then you have the options of a Wein cell battery, getting one of the expensive adapters, using a zinc air hearing aid battery and using something to hold it in place, or getting another 1.5v battery and adjusting the asa a few stops to make the meter accurate. It does seem confusing at first but just pick one and you’ll be happy.

I am not a DIY type and not into the camera enough to buy an adapter, so it is up for sale and that is not because of the battery issue.

Problem solved. I got an Olympus XA2 instead which I instantly fell in love with, I have been able to do my preferred fast and personal street shooting. I tried the rangefinder thing and glad I did, but it is not for me. So I guess that makes me irrelevant on this forum, as I soon wont have a rangefinder. Laterz all, thanks for the advice ☺
