Available Super8 cameras are more than 30years old. Even if they have solid mechanics - unfortunately they have weak electronics, cantacts, switches ....
Some selected Super8 cameras with reliable mechanics are the base for my modifications:
The camerabodies are dismounted, cleaned, lubricated and modified.
The old electronics has to be removed.
New designed electronics with microprocessor, LCD-panel and control buttons are mounted.
The optical system for the Super8MAX filmgate is slightly off-centre, but because it's such a small gauge no realignment is necessary!
The viewfinder was not designed to "see" the wider frame. Therefore, you have to compose the shots with this unmarked/unseen area on the right-hand side in mind.
