Non Hg devices
Although the following cameras were designed for and require a 1.35 volt cell, they include voltage regulation circuitry and thus do not require a mercury cell, an alternative cell of the correct voltage or an adapter. Alkaline batteries can be used instead. Each camera takes a single cell unless otherwise indicated.
(Many cameras and lightmeters were designed for and require a 625 mercury cell: list of cameras and list of exposure meters.)
