||The Tokina atx-i 100mm is a new macro lens capable of life-sized (1:1) magnification. The lens' multi-coating have been re-engineered to match the highly reflective silicon based CCD and CMOS sensors in today's digital SLR cameras. This lens gives the best of both worlds because optics still give full coverage and excellent sharpness on 35mm film. A macro lens that can handle both the digital and film worlds with ease.
The atx-i 100mm also has a very convenient focus limiter switch that can lock the focus out of the closes focus making it focus faster when used as a moderate telephoto lens that is excellent portraits as well.
Other features of the atx-i 100mm are:
Tokina One Touch Focus Clutch Mechanism for fast easy switching between manual and Auto focus.
55mm non-rotating filter thread for use with macro ring flashes and special effects filters.
The atx-i 100mm also comes with a deep bayonet mounted lens hood.
Available for Canon and Nikon cameras (see note below).
Focal length: 100mm
F-stop range: f2.8 to f32
Filter thread size: 55mm
Working distance at 1:1 (from end of lens to subject): 4.5""
Please Note: - The lens does not have its own motor, so it has to make use of the in-camera motor to autofocus. For this reason, it will not autofocus when used with a Nikon camera in the D3000 series or the D5000 series. It will autofocus with a camera that has a built-in motor, such as a D90, D300, D7000-7500, or any Nikon full-frame camera.
