Lomography "Actionsampler" aperture?
On my rounds through the thrift store today, I came across what I'm fairly certain is the pre-Lomography incarnation of this camera ("QUAD Camera"on the package). I figured it was worth the two dollars. Like a moron, I loaded it with a roll of 400 iso without really inspecting the lens array very carefully. Lomo heretic that I am, I'd like to actually meter for the damn thing and possibly get a proper exposure.
It seems like a fun diversion, but given what I paid for it, I don't want to explore the "dreamy world of lomo lifestyle" by burning up a roll of film. The package says the shots span one second, so I'm assuming the shutter is roughly 1/4 second. Any guesses for the aperture?
