Made in Japan

How to use it:

First set the correct ISO for your film.  Say 200.

Then point it at the spot you want to get the reading, look into the viewfinder, press trigger and get the red LED reading (for example, 11, see picture)

Then rotate the ring to 11, the speed/aperture pairs will show: 250/f4, or 125/f5.6 or 60/f8,..... these are the settings you can use.

There are signs of wear over the body.  Some small name plates are missing, which of course do not affect the operation, but the price is lowered.
