• Vibrations resistant lens for M42-mount cameras.
• Lineup of 18 models: focal lengths from 18 to 100 mm and F-numbers of maximum aperture, 5.6, and 8.0.
• A lock ring locking the surface and the improved design of internal structure increase resistance to vibration in comparison to the previous model. This enables application in environments where the point-locked lens is moved under the effects of ambient vibration.
• Install in narrow space without a lock screw.
