Olympus M.ZUIKO Digital 17mm f/1.8
Image quality: 9/10
Value for money: 7/10
The beautifully crafted, all-metal Olympus M.Zuiko Digital ED 17mm f/1.8 is a strong performer in the optical department, offering very good sharpness wide open, and excellent performance when stopped down to f/2.8 or f/4. The f/5.6 and f/8 settings also yield perfectly usable results, with good sharpness uniformity across most of the frame. As typical with smaller formats, diffraction takes its toll on resolution at f/11 and beyond, but this is hardly the lens's fault. Lateral chromatic aberrations are almost a non-issue and longitudinal CAs are not very intrusive, either, which is very good news for such a fast lens. At maximum aperture, there is some light fall-off in the image corners, but this essentially disappears upon stopping down to f/2.8. As common with wide-angle lenses, there is visible barrel distortion in the raw files, but this is quite well corrected in-camera and in most raw converters. Bokeh is really pleasant when shooting subjects that are fairly close to the camera.
Olympus M.Zuiko Digital 17mm 1:1.8 review
- Classic wide-angle prime
- Smooth and silent AF
- Larger than 17mm f/2.8 lens
- Some softening at f/22
This is where you see the advantage of Olympus's Micro Four Thirds format. This 35mm equivalent f/1.8 lens is a fraction of the size of a DSLR equivalent. Its optical performance is first rate too.
