Backlighting control enables new forms of expression
As strong light sources can often penetrate the lens, wide-angle lenses in particular are made to resolve backlighting issues. The Model A037 has gone through repeated comprehensive ghosting analysis simulation during the development stage. The optical structure performance level has also been maximized. The BBAR (Broad-Band Anti-Reflection) Coating is applied for highly effective anti-reflection and ghosting and flare are brought under control.
AF to capture the moment
The AF drive employs a newly developed OSD (Optimized Silent Drive) to ensure silent operation. Upgraded and optimized for even further reduction in drive noise, this drive allows the lens to be used to your heart's content in all situations where silence is required. With its greatly enhanced quality and speed, the new outstanding AF performance and tracking capabilities mean you never have to worry about missing a shot even when focusing on moving subjects.
Protect your lens with Fluorine Coating and Moisture-Resistant Construction
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints. Leak-proof seals throughout the lens barrel further protect your equipment, especially when shooting outdoors.
