The Holga 6x6 model looks to me like the perfect camera to tinker with. Has anyone modified one of these to use salvaged lenses and shutters? From the posts of Holga prints I have seen the camera seems to be a respectable lightproof container and film transporter. Holding the film flat without scratching is about all you can ask for twenty bucks. Who knows what a clever person could produce using a good salvage lens & shutter assebly from an old folder or a TLR parts camera?
