My wife bought me this yesterday. We have a charity shop in town that seems to specialise in cameras at times. Every so often, they'll have something interesting. Yesterday, they had this.

It's a Wray Stereo Graphic camera - which is why it has two lenses (obviously). It takes 35mm film. There's some Kodak Gold in it now - I have no idea how light fast it is, but I'll find out when I get the film processed. You get around 15 shots from a 24 exposure film.
It's an odd thing. It has a fixed shutter speed (1/50 second) or one you have to manually time or use with a flash. You can control the aperture using a knob on the front, which has some useful words on it like "hazy" or "bright". There are also f-stop numbers, but there's no automatic exposure settings, so you have to either use a light meter or "best guess" and pick the right word.
There's no focussing either. Some Googling tells me that it has a special system in place that makes everything in focus (read: focus on infinity). Not a bad thing, really. This isn't an SLR, and focussing would have to be based on known measurements or more guesswork.
The viewfinder is this tine 3x3 mm hole round the back. It's hardly useful for anything other than as a rough guide.
I've not taken any photos with it yet - but I'm hoping that if the weather holds out over the next few days, I'll be able to take it with me to a few places to try out.
