Panasonic Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. Lens
Key Features
  • Micro Four Thirds System
  • 85mm (35mm Equivalent)
  • Aperture Range: f/1.7 to f/22
  • One Aspherical Element
A standard portrait-length prime, the Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. from Panasonic is an 85mm-equivalent lens designed for the Micro Four Thirds system of mirrorless cameras. One aspherical element is incorporated within the optical design, which helps to control spherical aberrations and distortions for enhanced sharpness and accurate rendering. The f/1.7 maximum aperture is particularly beneficial for selective focus imagery, and also aids shooting in low-light conditions. Further cementing its place as a versatile tool for portraiture, the rounded seven-blade diaphragm produces a smooth out-of-focus quality when making shallow depth of field photos and movies.

Panasonic Lumix G 42.5mm f/1.7 Overview

A standard portrait-length prime, the Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. from Panasonic is an 85mm-equivalent lens designed for the Micro Four Thirds system of mirrorless cameras. One aspherical element is incorporated within the optical design, which helps to control spherical aberrations and distortions for enhanced sharpness and accurate rendering. The f/1.7 maximum aperture is particularly beneficial for selective focus imagery, and also aids shooting in low-light conditions. Further cementing its place as a versatile tool for portraiture, the rounded seven-blade diaphragm produces a smooth out-of-focus quality when making shallow depth of field photos and movies.

Complementing the optical attributes is a fast stepping AF motor and internal focus design, which provides smooth, quiet, and responsive focusing performance for intuitive handling. The POWER O.I.S. (Optical Image Stabilizer) also benefits hand-held use by compensating for the effect of camera shake for sharper imagery.

It's an OK zoom lens. I would prefer something with a lower apeture.

I've made 90% of my paying images in the past 25 years with either the Nikkor 105 1.8, the Zeiss Batis 85mm 1.8. Looks like this is my new best friend.

Even it's 3/4 lens, but in mostly condition, it worked well!

As sharp and contrasty as the Olympus 45/1.8

By Aaron

Excellent lens! sharp and contrasty, ultrafast focus, smooth focusing ring, small, light and with a very pleasing modern clean design. It feels high quality, the fact that it's made in Japan probably add to that feeling, I suppose. Very similar optical performance to the well know Olympus 45mm/f1.8, but with significantly closer focusing distance, and of course the great addition of IS. Only thing I would change is the front threads diameter so it would fit a 46mm cap; with the current 37mm it looks a bit strange and protruding, just an aesthetic thing. Using a simple step up ring 37mm--46mm fixes it easily, and it just looks better. It's of course also practical, if your other lens/s have 46mm diameter you can now just carry extra caps/filters with one diameter.

Small, light, fast focus, close focusing, Sharp. Comes with lens hood, case. Nice control over depth of field. Cons? Perhaps the tiny 37mm filters needed. Nothing a step up ring won't fix. Need a portrait lens for m4/3? Get this lens.
