Early Pocket Spot Baffles

Unpainted older metal baffle.

If you have an early Pocket Spot Meter, then the baffle in front of the lens (outside) will be one with several individual 'rings' made of anodized aluminum. If this is the case, there is an improvement to be done if it hasn't already been done. You should be able to tell. The edges of the rings, at least the forward most two, should be painted with flat black paint. Krylon UFB is the best, but most any will work. Put some on a Q-tip or paint brush, and go around those edges without getting any on the lens. This improves metering contrast. If you'd like us to do it, send it in.

If you have a baffle that appears to be threaded and made of plastic, then this is not an issue and you can sleep at night.
