Olympus flagship telephoto zoom with exceptional optics in a compact weather-sealed body.
The Olympus M.Zuiko Digital ED 40-150mm f/2.8 PRO is the telephoto anchor of Olympus's professional Micro Four Thirds lens lineup. Launched in 2014, it delivers an 80-300mm equivalent range at a constant f/2.8 in a package significantly smaller and lighter than equivalent full-frame 70-200mm f/2.8 lenses. It quickly earned a reputation as one of the finest MFT telephoto zooms.
Optical quality is outstanding with sharpness across the frame wide open, excellent contrast, and minimal chromatic aberration. Bokeh is smooth and pleasant for a zoom. Autofocus is fast, silent, and accurate via a linear motor system. The lens is fully weather-sealed, dust-proof, and freeze-proof. Build quality is exceptional with a metal barrel.
Micro Four Thirds mount only, 72mm filter thread. A 1.4x teleconverter designated MC-14 extends reach to 420mm equivalent. No other mount options exist. The lens remains current in the OM System lineup and has not been replaced since its 2014 release, testament to its enduring quality.
Used prices range from five hundred to seven hundred pounds depending on condition. Check the focus motor which should be silent, zoom ring smoothness, and weather seal integrity around the mount. Inspect for front element scratches. This lens holds its value well due to strong demand.
