Since a reflex lens is not equipped with a diaphragm system, the use of filters and the shutter speed control play an important factor in the control of light and contrast. In order to compensate focusing when normal positioning may be altered due to extreme temperature change, the focusing ring has been designed to allow rotation beyond the fixed marks of the distance scale. To avoid mistakes, always focus while looking through the viewfinder. T-Mount Included Thanks to the easy handling, the lens is also especially suitable for beginners.
