Tokina AT-X 124 AF PRO DX (Nikon)

This lens gives the Digital Photographer an ultra wide-angle zoom lens that has the equivalent of an 18-36mm zoom range on a 35mm\nfilm camera while maintaining a bright constant aperture of f/4.\n\nProfessional Features\n\n- Non-rotating 77mm filter threads mean special effect filters will not change when the lens’ focus is changed. Tokina recommends using HOYA PRO 1 Series low profile filters with the AT-X 124 PRO DX.\n\n- Fast internal focusing with Tokina’s One-Touch focus clutch mechanism allows the lens to AF focus faster and switching between auto and manual focus is as easy as snapping the focus ring back and forth.\n\n- 2 sharp-cut aspherical elements accurately correct aspherical aberration usually associated with ultra-wide angle lenses.\n\n- Bright, constant f/4 aperture allows plenty of light to enter the camera for shooting in a wide variety of photographic situations.\n\n- Chrome plated brass mount plate and all-metal zoom unit can stand up to regular use while advanced polycarbonate outer lens barrels reduce the weight of the lens, making it a pleasure to carry.
