This is a very nice vintage item. Extinction meters were an early form of establishing correct exposure. Look through the little eyepiece and turn the dial until you can barely see any light. Then look at the calculator dial. Not great by modern standards but it was acceptable in its day.
PLEASE CAREFULLY REALLY READ ALL OF THE FINE PRINT BELOW BEFORE PLACING YOUR BID
I primarily sell used photo equipment. As such it is usually not 100% perfect. I try to advertise items as honestly as I can, but if you are looking for
something that is 100 % perfect it might be better if you buy the item new. Also, I do NOT use stock photos.
