About OM System OM-1 and OM-5

Although the OM-1 still bears the “Olympus” label across its front, it represents the first camera to debut under the new “OM System” branding and the maiden release from OM Digital Solutions. This separate entity was formed after Olympus Corporation spun off its Imaging Division in 2021. Despite the name change, this camera essentially serves as the spiritual successor to the Olympus E-M1 Mark III, packing several upgrades and enhancements over its predecessor.

The physical design of the OM-1 remains largely unchanged, although there have been some welcome ergonomic improvements. The camera’s EVF also features a higher-resolution screen and larger magnification. Additionally, the OM-1 boasts improved durability, an impressive feat considering the Olympus OM-D-series cameras’ history of exceptional weather sealing.

The OM System OM-5 is a mid-range mirrorless camera with a 20MP Micro Four Thirds sensor, geared primarily towards still photography with a decent set of video features. Although its exterior and sensor are similar to the older OM-D E-M5 Mark III, the OM-5 has received a processing boost, enabling computational photography features that were previously only available on pricier cameras. With the OM-5, the OM System has been given a prominent position as the camera fully embraces the new branding. While this significant change hints at the potential for future cameras within the OM System, the OM-5 is not a revolutionary new design.

Design and Build Quality

The OM System OM-1 has a classic, vintage design that is often praised by photography enthusiasts. It has a solid metal body that feels durable and sturdy in the hand. The camera is relatively compact and lightweight, making it easy to carry around for extended periods. The OM-5, on the other hand, has a more modern design with a plastic body. While adopting the same ergonomic, the OM-1 feels heavier and more premium on hand; it is also bulkier than OM-5.

Features and Performance

Both the OM-1 and OM-5 offer advanced features that cater to the needs of professional photographers. The OM-1 has a micro four-third format and offers a 20MP resolution. It has a maximum continuous of 10fps with continuous drive. The OM-5 uses the same specs, but it is not a stacked sensor like the OM-1 and this camera can do 30fps continuous shooting.

One thing we love from the OM-1 is the viewfinder because it is much better and cleaner than the EVF on OM-5. In addition, the autofocus has improved immensely that it is now competing with the best mirrorless cameras in the market, a perfect choice if you often hunt for the subject.

Image Quality

When it comes to image quality, both the OM-1 and OM-5 offer excellent results. The OM-1’s stacked sensor produces excellent results that are highly sought after by some photographers. The OM-5’s Micro Four Thirds format produces just as good images in decent lighting but since these small sensors are not made for low-light applications, the high ISO performance is not as amazing as those with bigger sensor area. As for the video, the stacked sensor in OM-1 benefits faster readout, making this camera able to record 4K 60fps, something that OM-5 can only do at 30fps.
