Olympus OM-D E-M1 Mark III

It's been a little over three years since Olympus released its high-speed OM-D E-M1 Mark II, a camera that we liked a lot due to its pacey performance, excellent handling, and incredibly effective in-body image stabilisation (IBIS). Last year, the firm followed up with the E-M1X, a higher-end model with an integrated vertical grip for use with large lenses, and some really clever new features. It's an impressive camera, but due to its bulk and £2,200 body-only price, inevitably of niche appeal. Now the firm has revisited the smaller form factor with the E-M1 Mark III.

At first glance, the new model looks very much like its predecessor, with essentially the same core specifications and body design. Externally, the biggest update is the addition of a joystick for selecting the AF area. But the most important upgrade is inside, because the E-M1 Mark III debuts a brand new processor, the TruePic IX. This allows the inclusion of some of the best new features from the E-M1X, including LiveND that mimics the effect of neutral density filters up to 5 stops, and a hand-held high-resolution multi-shot mode that outputs 50MP images. But it also boosts many other aspects of the camera's operation, making the Mark III a more significant upgrade than it first appears.

At £1,600 body-only, the Mark III is distinctly aimed at serious photographers. Compared to other fast-shooting, weather-sealed models with IBIS, it costs £50 more than Fujifilm's impressive-looking new X-T4, and £200 more than the Sony Alpha 6600. It's about the same price as the full-frame Nikon Z 6, and £150 less than the Sony Alpha
