Used Gossen Luna-Pro Light Meter

This meter is the choice of professional photographers and discerning amateurs, all over the word. Experience proven, it provides accurate reflected or incident light readings in all kinds of light, from a flickering candle to bright summer sun. It can be relied upon to provide correct exposures in any situation. More than just a superb handheld meter, the Luna-Pro S has a wide range of optional accessories which further increase its versatility.

The Luna-Pro S can be adapted to calculate correct exposure for photomicrography with the optional Microscope Attachment. A Variable Angle attachment turns it into a dual angle "spot meter". It can be used to take through-the-lens readings from a large format camera's ground glass with the Flexible Fiber Optics Probe Attachment, or you can use it for copy work with the Copy Attachment. And its also handy in the darkroom; the Enlarging Attachment helps find the right paper grade for black and white prints.

Proven accuracy. Proven reliability. Proven versatility. That's why pros have chosen the Luna-Pro S since its introduction in 1963.
