Olympus M.Zuiko Digital ED 8-25mm f/4 PRO Lens

The M.Zuiko Digital ED 8-25mm f/4 PRO from Olympus is a versatile wide-angle zoom lens designed for the Micro Four Thirds system, offering an equivalent focal length of 16-50mm in full-frame terms. Its advanced optical architecture incorporates a range of aspherical, low dispersion, and high refractive index elements, effectively minimizing both chromatic and spherical aberrations across the entire zoom range, resulting in exceptional clarity, sharpness, and color fidelity. The lens is enhanced with a ZERO coating, which significantly boosts contrast in challenging lighting situations. In addition to its sophisticated optical features, this zoom lens boasts a constant maximum aperture of f/4 and a robust weather-sealed construction, making it suitable for diverse shooting environments. Furthermore, it is equipped with a Movie & Still Compatible autofocus system that delivers rapid, smooth, and silent focusing, along with a manual focus clutch that allows for immediate switching between autofocus and manual focus modes.

• Ultra wide-angle to portrait-length zoom lens designed for Micro Four Thirds mirrorless cameras provides an 8-25mm equivalent focal length range.
  
  
• Constant f/4 maximum aperture enables consistent low-light performance and selective focus control throughout the zoom range.
  
  
• The lens construction integrates one DSA (Dual Super Aspherical) element, one ED (extra-low dispersion) element, two aspherical ED elements, one Super ED element, one HR (high-refractive index) element, one Super HR element, and one HD element elements into its design to minimize aberrations, distortion, and color fringing throughout the zoom range while also contributing to overall image sharpness, clarity, and color accuracy.
  
  
• A ZERO (Zuiko Extra-low Reflection Optical) coating has been applied to individual elements to minimize lens flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions.
  
  
• Movie & Still Compatible (MSC) autofocus system benefits both photo and video applications due to its smooth, quiet, and fast performance.
  
  
• Manual focus clutch allows the focusing ring to be quickly pulled into place for direct, intuitive focus control.
  
  
• Programmable L-Fn (lens function) button for easily accessible settings adjustment.
  
  
• Dust-, freeze-, and drip-proof design ensure the lens' performance in inclement and harsh conditions.
  
  
• Front optic features protective fluorine coating.
  
  
• Rounded seven-blade diaphragm produces a smooth bokeh quality.
