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

film camera while maintaining a bright constant aperture of f/4.

Professional Features:

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.

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.

2 sharp-cut aspherical elements accurately correct aspherical aberration usually associated with ultra-wide angle lenses.

Bright, constant f/4 aperture allows plenty of light to enter the camera for shooting in a wide variety of photographic situations.

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.

" Less expensive by far than Nikon's or Sigma's 12-24mm, Tokina's optical quality is unsurpassed."Popular Photography lens test article published April 2005
