OM SYSTEM M.Zuiko Digital ED 8-25mm f/4 PRO Lens (Micro Four Thirds)

The M.Zuiko Digital ED 8-25mm f/4 PRO covers ultra-wide through standard in a
single lens — a 16-50mm full-frame equivalent — at a constant f/4, so exposure
holds as you zoom. That range makes it a one-lens solution for landscapes,
architecture and general shooting.

Optics

The formula combines a DSA (Dual Super Aspherical) element, Super ED, ED and
aspherical ED elements, HR and Super HR elements, and an HD element, working
together to control distortion, aberration and color accuracy across a demanding
zoom range. ZERO (Zuiko Extra-low Reflection Optical) coating reduces flare and
ghosting, and a rounded seven-blade diaphragm keeps out-of-focus areas smooth.

Focus and controls

• Movie & Still Compatible (MSC) autofocus for smooth, silent focusing.
• Manual focus clutch for immediate switching between autofocus and manual.
• Customizable L-Fn button.

Build

• Dustproof, freezeproof and drip-proof construction.
• Fluorine-coated front element repelling water, dust and fingerprints.
