Olympus OM-D E-M5 Mark III Review

November 21, 2019 | Mark Goldstein |

Image Quality

All of the sample images in this review were taken using the 20 megapixel Super Fine JPEG setting, which gives an average image size of around 8Mb.

The Olympus OM-D E-M5 Mark III produced images of excellent quality during the review period. It produces noise-free images at ISO 64 up to 1600, with limited noise starting to appear at ISO 3200.

ISO 6400 exhibits quite visible noise and loss of fine detail, and the fastest settings of ISO 12800 and 25600 are even noisier but still usable for small prints and web use. The corresponding raw files are inevitably more noisy at lower ISOs.

The image stabilisation system works excellently for both stills and video, even when hand-holding the camera at very slow shutter speeds.

The High resolution mode can create a 50 megapixel JPEG or an 80 megapixel RAW file, although it only really works for non-moving subjects.

The various Art Filters and Picture Styles produce special effects that would otherwise require you to spend a lot of time in the digital darkroom.


There are 9 ISO settings available on the Olympus OM-D E-M5 Mark III. The base sensitivity is ISO 200 but there is an expanded low sensitivity setting equivalent to ISO 64. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and the RAW equivalent on the right.

File Quality

The file quality settings available on the Olympus OM-D E-M1 Mark II include Basic, Normal, Fine and Superfine for JPEGs, and you can also shoot in Olympus’s proprietary ORF raw file format.

Long Exposures

The Olympus OM-D E-M5 Mark III lets you dial in shutter speeds of up to 60 seconds and has a Bulb mode as well for exposure times as long as 30 minutes, which is very good news if you are seriously interested in long exposure photography. The shot below was taken using a shutter speed of 1 second at ISO 64.



Image Stabilisation

The Olympus OM-D E-M5 Mark III comes with a five-axis sensor-shift image stabilisation (IS) system, which allows you to take sharp hand-held photos at slower shutter speeds than with cameras that lack this feature, up to an incredible 6.5 shutter speed steps of correction.

The following 100% crops are taken from images taken with the M.ZUIKO Digital ED 12-100mm 1:4.0 IS PRO lens at a shutter speed of 1/15th of a second, with and without IS. The image stabilisation system also works during video capture, producing remarkably steady hand-held footage most of the time.

High Resolution Mode

The Olympus OM-D E-M5 Mark III can create a 50 megapixel JPEG or an 80 megapixel RAW file in the High Resolution Shot mode, achieved by shifting the sensor in half-pixel steps and capturing eight images over a period of one second.

Olympus recommends that you mount the camera on a tripod or other stable surface to obtain sharp results.

Picture Modes

Olympus' Picture Modes are essentially pre-set combinations of saturation, contrast and sharpness, except for the i-Enhance mode that aims to optimise each photo individually. You can tailor each Picture Mode to your needs. The following examples demonstrate the differences across the available Picture Modes.

Art Filters

The Olympus OM-D E-M5 Mark III offers 16 different Art Filters, which allow you to quickly apply an artistic effect to a photo before taking it (JPEG images only).

Note that applying the Art Filters slows the camera down somewhat as the camera takes several seconds to process and save the image.
