The Nikon version of the Tokina AT-X 124 AF Pro DX 12--24mm f/4 lens can be used on other Nikon cameras thanks to the universal F-mount system. The Nikon F4 and all other variants of the F4 camera are capable of mounting and effectively using the Tokina 12--24mm lens.
Instructions
1. Mount the Tokina lens the same as a Nikon-brand lens by aligning the index mark on the lens barrel with the index mark on the camera body and twisting the lens counter-clockwise until the lens locks in place.
2. Set the F4 camera to program mode using the shutter speed dial (P on the dial). Because the Tokina 12--24mm lens does not have an aperture ring, program mode must be used in order for the aperture to adjust to the lighting conditions to take a correct exposure. Otherwise, in manual mode, the aperture will remain at maximum f/4 for all photographs.
3. Alternatively, set the F4 camera to shutter-priority mode using the shutter-speed dial (S on the dial). This allows the user to choose a shutter speed while the camera selects an appropriate aperture based on the meter reading in the camera. This allows for greater flexibility and control by the photographer than using the program method.
4. Set the F4 camera to autofocus (S or C) using the selector switch on the left-hand side near the bottom of the front of the camera. To focus the Tokina manually, switch the selector to manual (M) and use the electronic rangefinder in the viewfinder window of the camera to confirm proper focus.
