Our selection method
To build this list, we searched current listings for Micro Four Thirds cameras and narrowed the pool to seven models available as new mirrorless cameras from OM System and Panasonic. We shortlisted based on sensor size, video capabilities, lens kit availability, and stated features like image stabilization and weather sealing. All prices shown are pulled live from the store listing and reflect the price at the time you view them. We have not tested these cameras; our recommendations are based on published specifications and manufacturer information.
What matters when choosing
Sensor size and megapixels
All cameras in this list use a Micro Four Thirds sensor, which balances image quality with smaller lenses and lighter bodies compared with APS-C or full-frame systems. Most picks have a 20 to 29MP sensor, while the OM-5 listing states 50MP or more for high-resolution capture. The GH5S omits megapixels in its listing, so its resolution is not stated by the seller. Choose a higher-resolution sensor if you plan to crop heavily or print large, but know that lens quality and stabilization affect sharpness just as much.
Video features
For video, look at the recording format and limits. The Panasonic GH5M2 supports 4K 4:2:2 10-bit video with unlimited recording, which suits color grading and long takes. The E-M10 Mark IV cameras also record 4K but their listings do not state bit depth or recording limits. The OM-3 and OM-5 listings do not mention video resolution at all, so those are weaker choices if video is a primary need. The GH5S is video-focused but its listing omits key specs, so verify details before buying.
Lens kits and compatibility
Some picks ship with a lens, and others are body-only. The OM-3 includes a premium M.Zuiko 12-45mm F4.0 PRO lens, while the E-M10 Mark IV kits include either a standard 14-42mm or a compact EZ version. Body-only options like the OM-5, GH5M2, GH5S, and one E-M10 Mark IV require you to buy a lens separately. If you already own Micro Four Thirds lenses, a body-only pick is more cost-effective; otherwise, a kit with a lens is simpler for immediate shooting.
Image stabilization and weather sealing
In-body stabilization is a stated feature on the E-M10 Mark IV and the OM-5, and it helps with handheld stills and video. Weather sealing is only stated on the OM-3 and OM-5, making them the best picks for rain, dust, and outdoor conditions. The Panasonic models in this list do not state weather sealing, so they are better suited to controlled environments. If you shoot outdoors in variable weather, prioritize the OM System sealed bodies.
Body design and portability
Micro Four Thirds cameras are valued for their compact size, and this list includes several small bodies. The E-M10 Mark IV with the EZ pancake lens is the lightest complete kit here according to its listing, while the OM-3 and OM-5 add weather sealing to a compact form. The GH5M2 and GH5S are larger bodies designed for video work, with more physical controls and cooling capacity. Consider how much you will carry the camera on foot or in a bag when choosing between these designs.
Questions
What is a Micro Four Thirds camera?
Micro Four Thirds is an open standard for mirrorless cameras and lenses defined by the Micro Four Thirds System Standard Group. It uses a sensor smaller than APS-C or full-frame, which allows for smaller and lighter bodies and lenses while still producing high image quality. The system is designed for interchangeable lenses from multiple manufacturers, giving photographers flexibility in building a kit. For this guide, all cameras use a Micro Four Thirds sensor as stated in their listings.
Are Micro Four Thirds cameras good for video?
Yes, many Micro Four Thirds cameras are strong video performers. In this list, the Panasonic GH5M2 supports 4K 4:2:2 10-bit video with unlimited recording, which is a professional-level feature. The E-M10 Mark IV cameras also record 4K, though bit depth is not stated. If video is your priority, choose a model with stated video specifications like the GH5M2, and consider that climate and recording limits can affect long sessions.
Do I need a lens kit or body only?
It depends on your existing gear. If you are new to Micro Four Thirds, a kit that includes a lens, like the OM-3 with its PRO zoom or the E-M10 Mark IV with a 14-42mm, lets you start shooting immediately. If you already own lenses, a body-only pick like the OM-5 or GH5M2 costs less upfront, though you need a compatible lens to use the camera. Check the mount compatibility of your existing lenses before choosing body-only.
What is the difference between OM System and Panasonic Micro Four Thirds cameras?
Both brands build cameras for the Micro Four Thirds standard, but they emphasize different strengths. OM System cameras, like the OM-3 and OM-5, focus on stills photography with features such as weather sealing and in-body stabilization, and they often ship with compact lenses. Panasonic cameras, like the GH5M2 and GH5S, are known for video features such as 4K 10-bit recording and unlimited recording time. Choose based on whether you prioritize outdoor stills or video production.
How many megapixels do I need in a Micro Four Thirds camera?
Most Micro Four Thirds cameras in this list have a 20 to 29MP sensor, which is sufficient for large prints and heavy cropping. The OM-5 goes further with 50MP or more stated for high-resolution capture, though its listing does not specify the exact count. Higher megapixels help if you frequently crop or shoot for large-format output, but they also create larger files. For most users, a 20MP sensor offers a good balance of resolution and file size.
