Now we have scaled it down and its a perfect match for DSLR's. This 1 amp stepper motor clamps right on to your 15mm camera rods and swings in to mesh with any industry standard 32 pitch (0.8 mod) lens gear. Works great with Dragonframe. Motor included.

    I love these little focus motors. I use them primarily with Dragonframe.
    They are easily adjustable, reliable and the customer service from Berkey is top.

  2. Berkey Focus Motor

    Berkey Focus Motor.

    I use this motor for aperture ramping on a 24mm Cine lens, using GBTimelapse and an eMotimo TB3 move-shoot-move unit, for astro timelapses going from 1-2 hours before sunset to 3-5 hours after sunset.

    Aperture ramping using this motor totally eliminates aperture flicker.

    Excellent product, solid build, highly recommended.
