The OM-1’s higher score reflects its superior performance and features. However, the E-M5 Mark III has its advantages, such as its lower launch price of $1199 compared to the OM-1’s $2199. This makes the E-M5 Mark III a more budget-friendly option for those seeking a capable mirrorless camera.
Taking into account the scores and specifications, the OM-1 proves to be the better camera. However, potential buyers should also consider their budget and specific needs before making a decision.
Olympus OM-D E-M5 Mark III vs OM System OM-1 Overview and Optics
The Olympus OM System OM-1 surpasses the Olympus OM-D E-M5 Mark III in optics with a 9-point difference, scoring 69/100 compared to 60/100. Both cameras share several key specifications, including 20-megapixel resolution, Micro Four Thirds sensor size, Micro 4/3 lens mount, and built-in image stabilization.
The OM-1’s superiority in optics is primarily due to its advanced Stacked CMOS sensor and powerful TruePic X Dual Quad Core Processor. This combination results in a significantly higher DXOMARK sensor score of 85, compared to the E-M5 Mark III’s 55. The OM-1’s enhanced sensor technology allows for better image quality and low-light performance.
Additionally, the E-M5 Mark III has a faster shooting speed of 30 frames per second, which is triple the OM-1’s 10 frames per second. This advantage enables the E-M5 Mark III to capture fast-moving subjects and action shots more effectively.
However, the OM-1’s slower shooting speed should not be disregarded entirely, as it may still be adequate for many photography scenarios. Moreover, the OM-1’s higher overall optics score indicates that its superior sensor quality and processing power outweigh its lower shooting speed in terms of overall image quality.
In the end, the Olympus OM System OM-1 emerges as the better option for photographers prioritizing image quality and low-light performance. The Olympus OM-D E-M5 Mark III, on the other hand, is the better choice for those needing a faster shooting speed for action photography. Both cameras offer strong features, and the final decision should be based on individual preferences and requirements.

Minimum ISO (Native) Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image. | 200 | 200 | |
Maximum ISO (Native) Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise. | 6,400 | 25,600 | |
Minimum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 64 | 80 | |
Maximum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 25600 | 102400 | |
Minimum Shutter Speed The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory. | 60 s | 60 s | |
Maximum Shutter Speed The maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries. | 1/ 8000 s | 1/ 8000 s | |
Autofocus Points Autofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings. | 121 | 1,053 | |
In-body Stabilization In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake. |   | | |
Viewfinder Type The viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens. | Electronic | Electronic | |

Olympus OM-D E-M5 Mark III vs OM System OM-1 Video Performance
The Olympus OM-D E-M5 Mark III outperforms the Olympus OM System OM-1 in video capabilities, scoring 91/100 compared to the OM-1’s score of 83/100. Both cameras share some common specifications, such as a maximum video resolution of 4K and dimensions of 4096 x 2160. Additionally, both cameras have built-in time-lapse functionality.
The E-M5 Mark III’s higher score is due to its superior video frame rate, which reaches up to 120fps, allowing for smoother slow-motion footage. This feature gives the E-M5 Mark III an edge over the OM-1, which has a maximum video frame rate of 60fps. The faster frame rate in the E-M5 Mark III provides more versatility for capturing fast-moving subjects and creating professional-looking videos.
On the other hand, the OM-1 does not surpass the E-M5 Mark III in any video-related specifications. Its lower score reflects its limitation in video frame rate compared to the E-M5 Mark III. The OM-1 still offers solid video performance, but the E-M5 Mark III is the clear winner in this comparison.
Both cameras are excellent choices for photographers and videographers, but the Olympus OM-D E-M5 Mark III offers superior video capabilities, particularly in terms of maximum video frame rate. The OM-1 is a strong contender, but those seeking the best video performance should opt for the E-M5 Mark III.
