Lubitel 166 Universal
The Lubitel is the poor man's twin lens reflex camera. Being made of plastic, it is sometimes lumped into the toy camera category, but it does have a glass lens and other features like several aperatures and shutter speeds. Despite the apparent ability to "control" this camera, I have to admit that this isn't my favorite machine. Although bright, the screen is really hard to focus.
It has a ground circle in the center and a small magnifying glass to help with the task, but the results don't seem worth the effort. You are almost better off estimating the distance Holga-style. But all-in-all, it is capable of taking pretty sharp photos, and if you are willing to put up with its idiosyncracies, it can be a nice little camera.
