Released in 1964 the Yashica-Mat EM is an improved version of the Yashica-Mat LM in that it requires one less step in transferring the meter readings from the meter readout to the shutter speed and aperture wheels. The meter is a selenium cell, of course, so requires no battery. Some EMs have plastic thumb-wheels for adjusting aperture and shutter speed......this example has anodised aluminium thumb-wheels.

This lovely example has the superior, and much favoured,Yashinon f/3.5 80mm taking lens and the bright f/3.2 viewing lens in a Copal-MXV B 1-500 shutter. It occurs to me that many buy the Yashica 124G, which is usually higher priced, when the only real difference to the Yashica-Mat EM is the selenium compared to the CDS meter; and I can attest that the EM is far more reliable and of course has no risk of battery leakage (as it does not use one).

This EM looks lovely with no dents, and some very light signs of wear. The leatherette is fully intact with no tears, lifting or shrinkage.  The focus is smooth and feels like a new camera, and the operation of the waist level finder and pop-up magnifier are smooth.

The shutter is firing nicely on all speeds and 'sounds' right, all except for B, which is not working. The self-timer works and the light meter needle swings happily in response to light.
