I bought this spot meter some time ago to use with my Deardorff 8×10 camera.
It was considerably less expensive than the more popular Pentax alternative. For all that, it works just fine.
The readout uses old-fashioned ‘Light-up’ LEDs rather than LCDs, which I rather like. (It reminds me of the first digital device I ever saw, a Texas Instruments LED watch my Aunt Sheila brought over from America in 1977.)
Anyway, this meter is simple to use: you point it at the target and press the trigger. The E.V. value is displayed and you take your shutter speed and aperture from a rotating scale on the lens. Easy peas.
I don’t use it much now that I’ve sold my Deardorff, so I may just put it back on eBay someday soon…
(It proved very difficult to get a decent picture of the LEDs in action.)
