Q: 10. Hello and thanks in advance for the help to however is going replay; I do have 2 Sony lens ( SONY FE 24-70/2.8 GM LENS and Sony FE 16-35mm f/2.8 GM (G Master) i like to use the Tilta M motor but I don't know if this ring will be spinning on the lens or it will be mooving or is the best solution comparing to the soft follow focus ring? Once more thanks Fabry

A: Tilta makes their own rings which are measured for use with these specific lenses. For both the Sony FE 24-70mm f/2.8 GM II Lens and Sony FE 16-35mm f/2.8 GM Lens, Tilta recommends the Tilta Seamless Focus Gear Ring (81 to 83mm). This is what we would recommend for use with your set up. https://bhpho.to/3EYPODd
