You are using the lens wrong! The clamp is designed to keep the lens from changing focus when ON. You are moving the focus collar and slipping the clutch in the lens. Turn the clamp off and lens will work perfectly. If you want manual focus only use the switch on the camera body. Closeup macro works best with preset focus then moving camera in and out to achieve focus. Especially in the half to full life size range. Have fun macro is a blast.
