Canon EF 300mm f/4L IS USM Telephoto Lens for Canon SLR Cameras
Compact L-series telephoto lens with an Image Stabilizer which compensates for camera shake with the equivalent effect of a shutter speed two stops faster. Two Image Stabilizer modes are provided: Stabilizer Mode 1 (the same mode featured on the EF 75-300mm f/4-5.6 IS USM) and the new Stabilizer Mode 2 which steadies the image during horizontal or vertical panning. Mode 2 detects the panning direction automatically. The closest focusing distance is 4.9 feet (1.5 m).

Tokina 12-24MM F4 Pro II Zoom Lens for Digital Nikon SLR Cameras
The Nikon mount AT-X 124 PRO DX II has a built-in AF motor drive. The motor inside the lens was loaded onto the Nikon mount specification anew. The AF operates smoothly and quietly due to a DC motor that uses a new AF control gear assembly. With the built-in motor the lens can be used in AF mode with the Nikon D60 and D40 and other silent wave bodies.
The Canon version of the lens already has a built-in AF motor and will benefit from the improved multi-coating.
The optical system of original AT-X 124 PRO DX won awards for its sharpness world-wide. This design was maintained in the AT-X 124 PRO DX II and improved with the introduction of new multi-coating_ system. The new multi-coating helps reduce reflections that can cause flare and ghosting even more than in the AT-X 124 PRO DX.
The AT-X 124 PRO DX II features the one-touch focus clutch mechanism. _ To use the one-touch focus clutch mechanism move the focus ring forward towards the front of the lens for AF or back for MF. This allows for a fast and easy manual over-ride in difficult lighting situations.
