I played with this camera back in March. It is a very well made, simple camera. Using a bellows would increase the price of the camera, make it more complex to operate and make is less durable.

The camera, as Lachlan 717 mentioned is designed to take a standard 4x5 film holder so it isn't just for paper. On the pre-production version the holder slides in and is held securely. Using a graflok style back would drastically increase the price is isn't necessary for a pinhole. If you sight along the edges of the cone you can estimate the field of view.

Some of you seem to be bashing the camera without any knowledge or hands-on experience with the camera, or don't have an interest in a pinhole camera. Maybe you could lighten up a little. It is a nice little camera for what it is intended. I told Harman that I would hope that it would be around $150, but other than that, it should do well for its intended market
