Olympus has announced the OM-D E-M1 Mark III today, updating the OM-D E-M1 Mark II which was released back in 2016. So what are the differences between this new model and the older one, and what's the same? Here, we compare the specs to find out which one is best on paper. 

The OM-D E-M1 Mark II will remain on sale at a revised price point of £1299 body only (on Amazon it's currently £1199 body only). The OM-D E-M1 Mark III will retail for £1599.99 body only.

The new OM-D E-M1 Mark III on the right above looks very similar to its predecessor. There's a 3-inch vari-angle touch screen on the back, with a D-Pad and playback/menu/record buttons. The camera features the same sensor - a 20.4-megapixel live MOS with a special coating for dust reduction. There's 5-axis image stabilisation, and there are 121 AF points (all cross-type) just like the OM-D E-M1 II. 

They both offer 4K video recording and a 50-megapixel multi-shot mode.

Aesthetically, the function button on the right shoulder has been replaced with an ISO button. The fonts and symbols on the dials have been updated and there's also the addition of a joystick next to the screen. The 'Menu' button has been moved to the top left, and the 'info' button has moved down. 

Olympus boasts that the new camera offers the world's best image stabilisation performance with up to 7.5 EV (Exposure Value) steps of compensation. This a full one-stop more than the OM-D E-M1 Mark II offered. 

There's a new image processor - TruePic IX, an upgrade to the TruePix VIII found in the OM-D E-M1 Mark II. 

Live ND is also available on the OM-D E-M1 Mark III. This is a feature that was first seen on the OM-D E-M1X, released in early 2019. The features allow users to select the level of ND filter from ND2 (1 stop) to ND32 (5 stops) and review the effect in the viewfinder before capturing an image. 

Previously, the largest size of image you could shoot on the OM-D E-M1 Mark II was 50-megapixels, using the high-res multi-shot mode. Now, you can create 80-megapixel images using the high-resolution tripod shot mode, as well as capturing 50-megapixel images hand-held.

Faster, more accurate AF options

Using the multi-selector joystick (something that was also introduced on the OM-D E-M1X) you can quickly shift AF areas with your thumb while looking through the viewfinder - this can also be done during sequential shooting, meaning that you can keep the focus on even the most erratically-moving subjects, such as wildlife.

Face-priority and Eye priority AF has been improved, so it's now more advanced, and more accurate, on the OM-D E-M1 Mark III. 

Olympus Say that Starry Sky AF, a new feature for the Olympus OM-D E-M1 Mark III will revolutionise the world of astrophotography. The powerful image stabilisation means that it's now possible to shoot astrophotography hand-held with a wide-angle lens. Amazing! 

The second Starry Sky AF mode, called 'Accuracy Priority', uses a fine-tuned focus scan, and is effective for shooting specific stars with telephoto lenses.

The new OM-D E-M1 Mark III uses the same battery as the older model. The BLH-1 can be charged in as little as 2 hours and with the Mark III is rated to 420 shots, or 900 shots with Quick Power Save switched on. 

The OM-D E-M1 Mark III has some interesting updates compared to its predecessor, so we'll be interested to see where it ranks in our Best Mirrorless Premium Cameras Roundup - can it knock the Sony Alpha A7R Mark II off the top spot? We'll have to see!
