Vintage Bewi Automat “A” Exposure Meter

Straight from the desk of a mid-century designer, this super cool (and fully working) selenium cell exposure meter is a joy to use and play with.


The first thing I noticed about it is that unlike typical meters from this period (the 1950s) there’s no visible meter needle or pointer. Everything that moves does so inside. I know, I took it apart to see what was going on and there was the needle being “busy” reacting to light. Maybe this ad will do a better job at describing just what makes this meter so special.



Semi-transparent cover over the selenium cells allows for incident light readings.


Selenium cells exposed for full reflected light readings.


In its case, it’s about the size of a deck of cards but it fits nicely in the palm of your hand. I have it available in my shop as it’s time to pass it along to the next collector. You can see additional pictures of it and a complete description at
