Chronology
Predecessor	Olympus OM-D E-M1 Mark II
Successor	OM System OM-1

The E-M1 Mark III follows the E-M1 Mark II in embracing artificial intelligence-based features such as a deep learning autofocus system and multi-shot image processing to simulate neutral-density filters and a hi-res mode that allows the 20-megapixel camera to produce 50-megapixel images while handheld and 80-megapixel images while being on tripod. The camera also includes a 60 frames-per-second continuous shooting mode.^[2]

Features

• 20.4-megapixel Micro Four-Thirds sensor
• 121-point autofocus system
• Image stabilization (up to 7.0 EV or up to 7.5 with 'Sync IS' lenses)
• ISO range: 200 to 25600, with "LOW ISO 64"
• Handheld high-resolution shot mode
• Starry Sky AF for Astrophotography
• Up to 60 frames per second
• Multi-shot mode simulates ND filters (ND2, ND4, ND8, ND16, ND32)
• LCD viewfinder
• 3 inch screen
• 420 shots per charge
• Dual SD card slots (1 x UHS-II, 1 x UHS-I)
• 8-way joystick
• IPX1-rated weather sealing
• USB charging

Hi-resolution shot mode

In tripod and handheld mode, the camera rapidly captures 8 images (Tripod) or 16 images (Handheld) which are combined into 160 Mpx (tripod) or 320 MPx (handheld) of data, which the camera combines into 80 MPx (10368×7776 px) images in tripod mode or 50 MPx (8160×6120 px) image in handheld mode.^[3] The tripod mode ISO limit is 1600, or ISO 6400 in handheld mode. Pictures can be saved in RAW or JPEG format. Handhold exposure can be set up to 4 seconds.^{[citation needed]}

The benefit of hi-res mode is bigger resolution, low noise and an increase of dynamic range.^[4][5]

Reception

The E-M1 Mark III was generally favored for improvements made over the Mark II, such as the introduction of a handheld mode and a lower base cost.^[6]

The camera took criticism for including the same 20-megapixel sensor, electronic viewfinder, and screen, as its predecessor, the Mark II. The same sensor is also present in the enthusiast-level Olympus OM-D E-M5 Mark III which was released just months earlier.^[7]
