Designed for ultra-high magnification shooting and built for adventures, the M.Zuiko Digital ED 90mm f/3.5 Macro IS PRO is the ideal field macro lens for Micro Four Thirds shooters. This telephoto prime mixes a 180mm-equivalent focal length with a 2:1 maximum magnification for close-up shooting at a greater-than-life-size scale. Coupled with an intuitive manual focus clutch mechanism, quick AF performance, and optical image stabilisation, this is a versatile lens for handheld shooting, and IP53 weather sealing makes it suitable for use in harsh weather conditions.

High Magnification and Close Focusing
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. The minimum focusing distance of 22cm translates to a minimum working distance of about 8.89cm from the front of the lens. A manual focus clutch mechanism reveals magnification and focus distance markings on the lens barrel for easier recognition of the focusing position. The 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.
M.Zuiko PRO Optics
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, colour accuracy, and sharpness. Optical design has been optimised to suppress chromatic aberrations and colour 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 colour fidelity when working in strong lighting conditions.
High-Precision Focus and Image Stabilisation
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 more responsive focusing action. Optical image stabilisation reduces the appearance of camera shake to provide sharper imagery when shooting handheld. When used in conjunction with cameras featuring in-body image stabilisation, Sync IS utilises both lens and camera-based stabilisation systems and corrects for up to 7 stops of camera shake across five axes.
Physical Design and Handling
IP53-rated weather sealing guards against dust and splashes, as well as temperatures down to 14°F, for confident use in harsh weather conditions. The 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. The l-Fn button is featured on the side of the lens for making lens-based settings adjustments. Despite being a 180 mm-equivalent telephoto lens, this lens sports a relatively sleek and lightweight design, measuring just 137.16 mm long and weighing 453.59g.
