Introducing the world’s widest full-frame constant F2.8 lens at 12-24mm. Spectacular G Master resolution and drastically reduced chromatic aberration is realized from 3x Extreme Aspheric, 1x Aspheric, 2x Super ED (Extra-low dispersion) and 3x ED elements. Nano AR coating II suppresses reflections, flare and ghosting while the constant F2.8 and 9-blade circular aperture delivers on beautiful bokeh. Fast, precise autofocus tracking comes from 4x XD (Extreme Dynamic) linear motors.

• World’s widest full-frame constant F2.8 12-24mm zoom: Introducing the world’s widest full-frame constant F2.8 aperture zoom lens1 with 12-24mm focal length. The ultra-wide 12mm fills your frame with full scenes of Landscapes, architecture, street views and even sports.
• Crisp clear images: Three ED (Extra-low Dispersion) glass elements that reduce chromatic aberration, plus two Super ED glass elements that provide even more powerful chromatic aberration suppression, combine to minimize color fringing in high contrast scenes which challenge wide angle lenses.
• New Nano AR Coating II enhances clarity: A new Nano AR Coating II has been developed that can be evenly applied to large lens elements or highly curved element surfaces to suppress internal reflections and minimize flare and ghosting for clear, crisp imagery.
• XD Linear Motors achieve outstanding AF performance: The FE 12-24mm F2.8 GM employs four high-speed, high-thrust XD (Extreme Dynamic) Linear Motors, two for each of the lens’s focus groups, for fast, precise continuous autofocus and tracking.
• Dust and moisture resistant: The dust and moisture resistant design make this lens appropriate for heavy-duty outdoor use, especially when combined with a camera that employs weather resistant measures, providing the reliability needed in challenging conditions.
• Beautiful G Master Bokeh: Fine tuning of the lens’s spherical aberration characteristics during both design and manufacture contributes to its impressive blend of high resolution and smooth bokeh.
• Customizable multi-function focus hold button: A focus hold button, focus mode switch, zoom ring, focus ring, and other controls are designed and positioned for easy operation and a smooth workflow.
• Natural, linear manual focus response: Linear Response MF (manual focus) ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, so control feels immediate and precise.
• Instant auto/manual focus selection: Instantly and quickly switch between auto and manual focus via an AF/MF switch on the side of the lens. This makes operation faster and easier as you let the camera and lens focus for you or decide to take control and manually focus on the precise point you choose.
• Fluorine front element coating: The front lens element features a fluorine coating that repels water, oil, and other contaminants, while making it easier to wipe off any contaminants or fingerprints that do become attached to the lens surface.
• Integral petal-style lens hood: An integral lens hood effectively blocks off-axis light that can cause flare and ghosting. The supplied lens cap covers the hood, attaching easily and locking securely with the hood at any angle.
• Moviemaking advantage: The FE 12-24mm F2.8 GM lens has clear advantages for moviemaking. With an ultra-wide 12mm angle of view, four XD (Extreme Dynamic) Linear Motors for fast, precise and quiet autofocus and tracking, this lens is ideal for all types of content creators.
• 35mm equivalent on APS-C and Super-35bodies: The FE 12-24mm F2.8 GM lens is highly recommended for full-frame as well as APS-C and Super-35 users. It balances well on smaller format bodies, providing a very useful wide-angle focal length of 18-36mm (35mm full-frame format equivalent).
