The Gamma shutter consists of two curved aluminium curtains and each curtain has a curved toothed rack which is engaged by a spring loaded pinion. The spring loadings are adjustable to balance the curtain crossing speeds. Being seven years and scores of cameras since I restored my Gamma III I cannot recall the curtain latching method but like the Leica mechanism the curtain crossing speeds are fixed and the shutter fast speeds are controlled by the slit width between the curtains. The slow shutter speeds are controlled by an escapement and can be engaged by a lever under the fast dial while the fast dial is at any setting. To engage any fast speeds the slow lever must be set on the red asterisk.

Gamma from Italy should not be confused with Gamma Optikail Művek of Budapest, Hungary, makers of the Gamma Duflex.

Gamma (Gamma Officine Meccaniche de Precisione) was an Italian camera maker founded by Ireneo Rossi and based in Rome. It worked together with lens maker Koristka in Milan and later Officine Galileo. It made the rangefinder camera Gamma as well the Perla. Gamma ceased camera production in 1957 or 1958. The Gamma shutter consists of two curved aluminium curtains and each curtain has a curved toothed rack which is engaged by a spring loaded pinion. The spring loadings are adjustable to balance the curtain crossing speeds. Being seven years and scores of cameras since I restored my Gamma III I cannot recall the curtain latching method but like the Leica mechanism the curtain crossing speeds are fixed and the shutter fast speeds are controlled by the slit width between the curtains. The slow shutter speeds are controlled by an escapement and can be engaged by a lever under the fast dial while the fast dial is at any setting. To engage any fast speeds the slow lever must be set on the red asterisk.
