I seem to gaining a collection of batteryless Exposure Light-meters. Sekonics appear to hold their sensitivity much better than Weston models.
Here it is:
Notice that there is no scale on the meter, unlike foot-candles on other models. You turn the circular scale until the cursor thingy in the meter window lines up with the needle. So ... what is the foot-candles for a given circular scale position??
From the image it for example is recommending f/2.8 at 1/60 sec at ISO 100 equivalent to about 83 foot‑candles
