The Tokina AT-X M100 AF PRO D is a new macro lens capable of life-sized (1:1) reproduction at 30 cm. 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 AT-X M100 AF PRO D 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 AT-X 100 PRO D are:
Note: Autofocus with this lens is not supported with Nikon DSLRs that do not have a focus motor in the camera body.
Tokina AT-X M100 AF PRO D for Nikon mount conforms to the specifications of "Ai AF-D" Nikon lenses.
When using with a Nikon DSLR camera or a film camera with CPU system, it is necessary to set the aperture ring to the minimum aperture value (f/32).
To prevent accidental movements of the aperture ring from the minimum aperture value the ring can be locked in place with the small slide switch adjacent to the ring (to release the lock, slide the lever to the opposite side).
When setting the aperture value to f/32 and then changing it by the dial on the camera, the aperture value displayed in the viewfinder will be other than f/32.
At this time, the diaphragm blades do not move but will operate according to the aperture value displayed when shuttering.
Note: When set on other than the minimum aperture value (f/32), the "FEE" error message flashes and the shutter cannot be released.
