Lensse recently released a new Dual Follow Focus called the S5. At NAB 2015, I finally had a chance to test the unit out in person. The black anodized metal body S5 uses a quick 15mm clamp for mounting, incorporates A/B hard stops, 360 degree rotating marking indicator, front or rear mounted gear design, Left or Right handed operation, and adjustable focus drag.
For a very very limited time, if you opt to use COUPON CODE: cheesycam50, you'll receive $50 USD off the retail price. For more information about the Lensse Dual Follow Focus S5, visit their website at Lensse.com (here).
