The M.Zuiko Digital ED 90mm f/3.5 Macro IS PRO, developed by OM SYSTEM, is specifically engineered for ultra-high magnification photography and is well-suited for adventurous environments. This macro lens serves as an excellent choice for Micro Four Thirds users, offering a telephoto prime with a focal length equivalent to 180mm and a maximum magnification of 2:1, allowing for close-up photography at a scale larger than life. It features an intuitive manual focus clutch mechanism, rapid autofocus capabilities, and optical image stabilization, making it a highly adaptable lens for handheld use. Additionally, its IP53 weather sealing ensures reliability in challenging weather conditions.

• Offering up to 2x magnification, this lens can reproduce virtually microscopic subjects with greater-than-life-size rendering, making it perfect for highlighting details of small subjects like flowers, insects, coins, and other intricate objects.
  
  
• Minimum focusing distance of 8.8" translates to a minimum working distance of about 3.5" from the front of the lens.
  
  
• Manual focus clutch mechanism reveals magnification and focus distance markings on the lens barrel for easier recognition of focusing position.
  
  
• Floating focus design maintains sharpness throughout the focusing range, offering matched image quality from minimum focusing distance up to infinity.
  
  
• When used with the optional MC-14 or MC-20 Teleconverter, the effective maximum magnification can be increased to 2.8x or 4x, respectively.
  
  
• Optical design includes a variety of extra-low dispersion and high refractive index glass elements to reduce various aberrations and produce imagery with a high degree of clarity, color accuracy, and sharpness.
  
  
• Optical design has been optimized to suppress chromatic aberrations and color fringing at close range for more realistic and detailed rendering.
  
  
• ZERO (Zuiko Extra-low Reflection Optical) coating suppresses flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.
  
  
• Despite the long focal length and close-focusing performance, this lens features an adept MSC (Movie & Stills Compatible) autofocus system that achieves quick and quiet focusing performance with high accuracy.
  
  
• AF is supported at the closest focusing distances and can be used in conjunction with Focus Stacking functions that automatically move the focus position in between exposures.
  
  
• Internal focusing design, which uses two focusing lens groups, maintains the overall lens length during use for greater usability at close range and for more responsive focusing action.
  
  
• Optical image stabilization reduces the appearance of camera shake in order to provide sharper imagery when shooting handheld.
  
  
• When used in conjunction with cameras featuring in-body image stabilization, Sync IS utilizes both lens and camera-based stabilization systems and corrects for up to 7 stops of camera shake across 5 axes.
  
  
• IP53-rated weather sealing guards against dust and splashes, as well as temperatures down to 14°F, for confident use in harsh weather conditions.
  
  
• Front element features a protective fluorine coating that repels moisture, dirt, and oils, and is easier to clean than an uncoated surface.
  
  
• As an alternative to AF, manual focus control is benefitted by a focusing clutch mechanism for rapidly transitioning between focusing methods by pushing or pulling the focusing ring.
  
  
• A focus limit switch can constrain the available focusing range for faster focusing, especially when focusing solely on close-up subjects.
  
  
• L-Fn button is featured on the side of the lens for making lens-based settings adjustment.
  
  
• Despite being a 180mm-equivalent telephoto lens, this lens sports a relatively sleek and lightweight design, measuring just 5.4" long and weighing 1 lb.
