Our selection method
We searched the catalog for every camera listed under the OM SYSTEM brand and found 16 listings. After removing near-duplicate color and bundle variations, we narrowed the field to 10 distinct models. We shortlisted based on the specifications each seller states, such as sensor format, video resolution, lens kit, and weather sealing. We also considered the Micro Four Thirds system standard, which is described on the four-thirds.org site, and the brand transition from Olympus, as explained on the Olympus global page. Prices are read directly from each store listing and may change. None of these cameras have been tested by us; we rely on the make and seller's published information.
What matters when choosing
Micro Four Thirds: the shared system
Most mirrorless OM SYSTEM cameras in this guide use the Micro Four Thirds standard, an open lens mount shared across multiple manufacturers. According to the four-thirds.org site, this open standard lets you combine bodies and lenses from different brands. That means you are not locked into a single lens line. If you already own Micro Four Thirds optics, a body-only model like the E-M10 Mark IV can be a smart addition. If you are starting fresh, a kit such as the OM-3 with its PRO lens gives you a proven starting point.
Sensor and resolution: what the numbers tell you
The pool lists a mix of sensor information. Some entries state "Micro Four Thirds" (such as the OM-3, OM-5, and E-M10 Mark IV), while others omit the sensor entirely. Resolution ranges from "Under 20 MP" (the 12MP TG-7) to "20 to 29 MP" on the E-M10, and one listing claims "50 MP or more" for the OM-5, which is unusual and may be a seller error. For general photography, 20MP is plenty; for large prints, higher counts help, but you should verify the OM-5's spec from the manufacturer before relying on it.
Video: 4K availability by model
Only a few picks explicitly state 4K video: the E-M10 Mark IV, the PEN, and the TG-7 variants. If you plan to shoot video, check that your chosen model lists 4K. The TG-7 also notes 2160p (another name for 4K) in one bundle. None of the OM-3 or OM-5 listings mention video resolution, so they may lack 4K or the seller just omitted it. For a video-first purchase, the E-M10 Mark IV kit with lens is the most straightforward.
Weather sealing and ruggedness
Outdoor photography often demands protection from rain, dust, or submersion. The TG-7 series is specifically marketed as waterproof and freeze-proof, making it the top choice for underwater use. Among mirrorless models, the OM-5 and PEN claim weather-sealed designs in their names, while the OM-3 does not list that feature. If weather resistance is non-negotiable, focus on the OM-5 or PEN; if you need to go deeper, the TG-7 rugged compacts are the only ones built for submersion.
Lens kit vs. body only
Some listings include a lens, others do not. The OM-3 ships with a M.Zuiko 12-45mm F4.0 PRO lens, the E-M10 Silver includes a 14-42mm EZ lens, and the PEN comes with a 14-42mm III lens. Body-only options like the E-M10 Black and OM-5 require you to own or buy lenses separately. For beginners, a kit eliminates the initial lens decision. For experienced users, body-only lets you reuse existing glass and avoid paying for spare lenses you do not need.
Compact vs. mirrorless: choose the form factor
The TG-7 compacts are fixed-lens cameras, smaller and simpler, ideal for pocketable travel. The mirrorless models (OM-3, OM-5, E-M10, PEN, E-M1X) offer interchangeable lenses but weigh more and cost more. The PEN is the most compact mirrorless in the list, while the OM-D E-M1X is the largest and most professional. Decide whether you prioritize portability or system flexibility; that choice narrows your list quickly.
Questions
What does OM SYSTEM mean?
OM SYSTEM is the camera brand used by OM Digital Solutions, which took over the Olympus camera business in January 2021. The Olympus global site confirms that cameras, audio, and binoculars previously under Olympus are now handled by OM Digital Solutions. As a result, many new models carry the OM SYSTEM name, while older models may still show the Olympus logo.
Are Olympus cameras still being made?
Yes, but under the OM SYSTEM brand. The Olympus global page states that since January 2021, cameras and audio products have been transferred to OM Digital Solutions. That company now produces cameras like the OM-5 and TG-7 series. Products sold today are mostly listed as OM SYSTEM, although some older stock remains under the Olympus name.
Is Micro Four Thirds a good system for beginners?
Micro Four Thirds is a compact, lightweight system ideal for beginners, as noted on the four-thirds.org website. The open standard means you can mix bodies and lenses from multiple makers, giving you lots of affordable options. The E-M10 Mark IV kit, for example, includes a lens and is easy to learn on. The smaller sensor also keeps lenses small, which reduces the initial cost and bulk.
Can I use Olympus lenses on OM SYSTEM cameras?
Yes. Since OM SYSTEM continues the Micro Four Thirds mount, all Olympus Micro Four Thirds lenses work on OM SYSTEM bodies. The OM-3, OM-5, and E-M10 all use the Micro Four Thirds mount, so your existing lenses are compatible. The four-thirds.org site confirms that the Micro Four Thirds standard is open, meaning you can swap lenses across brands like Panasonic, Leica, and others that support the mount.
Which OM SYSTEM camera is best for underwater photography?
The Tough TG-7 series is the only one with waterproofing stated in the product name. If you plan to dive or snorkel, the TG-7 (in any of its bundles) is the clear choice. Most mirrorless models do not have waterproofing and would require a separate underwater housing. For a rugged, grab-and-go underwater camera, the TG-7 Red or the bundle with a 64GB card are the ones to consider.
Do all OM SYSTEM cameras record 4K video?
No. Only some listings state 4K: the E-M10 Mark IV (both versions), the PEN, and the TG-7 models that specifically mention 4K. The OM-3, OM-5, and E-M1X listings do not mention video resolution, so you should assume they might not offer 4K unless you verify with the manufacturer. Always check the product description for the video resolution before buying if 4K is essential.
