The M.Zuiko Digital ED 300mm f/4 IS PRO from Olympus is an extensive super telephoto lens designed for Micro Four Thirds mirrorless cameras, offering a 600mm equivalent focal length. This lens expertly combines advanced optical design with a lightweight, hand-holdable structure. It incorporates Super ED, E-HR, and HR glass elements to effectively minimize both chromatic and spherical aberrations, ensuring exceptional clarity and sharpness. Additionally, a Z Coating Nano has been applied to the individual elements to reduce lens flare and ghosting, resulting in high-contrast and color-accurate images.

In addition to its optical excellence, this lens features an optical image stabilization system that works in tandem with the camera's sensor-shift IS, achieving a six-stop effective reduction in camera shake for enhanced handheld shooting. The lens is equipped with a Movie & Still Compatible (MSC) autofocus system, providing rapid and silent focusing capabilities. A manual focus clutch allows for easy switching between autofocus and manual focus, enhancing user experience. Furthermore, the lens includes a removable rotating tripod collar for improved stability and support, and it is weather-sealed to protect against dust, moisture, and freezing conditions, making it suitable for use in challenging environments.

• Super telephoto prime is designed for Micro Four Thirds mirrorless cameras and provides a 600mm equivalent focal length.
  
  
• Three Super ED (extra-low dispersion) elements are used to control color fringing and chromatic aberrations for improved clarity and color accuracy.
  
  
• Three high refractive index elements and one E-HR (extra-high refractive index) element help to minimize spherical aberrations and distortion for greater sharpness and accurate rendering.
  
  
• A Z Coating Nano has been applied to individual elements to significantly reduce lens flare and ghosting to improve contrast and color fidelity when working in strong lighting conditions.
  
  
• Lens-based image stabilization helps to minimize the appearance of camera shake to benefit shooting handheld with this lens in difficult lighting conditions. Additionally, this lens supports Synchronized IS, which pairs the optical IS system with select Olympus cameras' 5-axis sensor-shift image stabilization to control up to six stops of camera shake.
  
  
• Movie & Still Compatible (MSC) autofocus system benefits both photo and video applications due to its smooth, quiet, and fast performance.
  
  
• Manual focus clutch lets you quickly pull the focusing ring into place for direct, intuitive focus control.
  
  
• Programmable L-Fn (lens function) button for easily accessible settings adjustment.
  
  
• Dust, splash, and freezeproof construction incorporates 17 separate seals to ensure this lens's performance in inclement conditions and harsh environments.
  
  
• Removable rotating tripod collar offers a stable platform for working with this lens atop a tripod or monopod. The included DR-79 Decoration Ring can also be used on the lens when shooting handheld to take the place of the removed tripod collar.
  
  
• Built-in retractable lens hood shields the front lens element to reduce surface reflections and flare.
  
  
• Compatible with the optional M.Zuiko Digital MC-14 1.4x Teleconverter to further extend the reach to a 840mm equivalent focal length.
