The AT-X M35 PRO DX boasts Tokina's exclusive One-touch Focus Clutch Mechanism. This groundbreaking feature allows the photographer to switch between Auto Focus and Manual Focus by simply snapping the focus ring forward for Auto and back towards the camera to focus manually. There is no need to change the AF-MF switch on Nikon cameras and there is no second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring.
Paul Kench, Kenro's managing director says: "Being able to shoot high quality 'life size' Macro images is the dream of many photographers. This lens is the answer to their prayers. The fast aperture will also be of great benefit when shooting under low lighting conditions or where the photographer needs to 'freeze' moving images such as when flowers are moving in the wind."
