If you want a small camera that accepts interchangeable lenses, start by choosing between a viewfinder-equipped body and a screen-first one, then compare the complete camera-and-lens kit—not just the body. The available product information supports three useful candidates, but not a defensible ranking of five models or a current, like-for-like price comparison.
What “compact interchangeable-lens camera” means
These are mirrorless cameras that let you change lenses. “Compact” describes the body relative to many camera systems; it does not mean the camera will fit in a pocket. A long zoom or bright lens can make even a small body a substantial carry. Compare the size and weight of the body with the lens you expect to use.
They are different from fixed-lens compact cameras: the lens is replaceable, but that flexibility comes with a system choice. Each camera uses a lens mount, and choosing a body also means considering which compatible lenses are available to you.

These are candidates for different needs, not a universal top-three ranking. The cited sources do not establish a consistent five-camera comparison.

Canon EOS R50: a beginner-focused option
The EOS R50 is a mirrorless interchangeable-lens camera with Canon’s RF mount. Canon lists RF and RF-S lenses as compatible. An EF-EOS R adapter allows use of EF and EF-S lenses, while EF-M lenses are excluded. Check the exact lens and adapter compatibility before buying, especially if you already own lenses. Canon’s EOS R50 specifications
Tom’s Guide highlights the camera’s subject-detection autofocus and vari-angle display in its comparison with the EOS R100, and positions the R50 for beginners. Those are the publication’s assessments, not controlled measurements or a claim of hands-on testing for this guide. Tom’s Guide’s mirrorless-camera roundup

Nikon Z50II: an option with an electronic viewfinder
Nikon lists the Z50II as an interchangeable-lens camera with a Nikon Z mount, an electronic viewfinder, and a DX-format sensor measuring 23.5 × 15.7 mm with 20.9 million effective pixels. Its compatible lenses include NIKKOR Z lenses; F-mount NIKKOR lenses can be used with an adapter, subject to restrictions. Nikon’s Z50II specifications
Nikon USA says its Z system includes more than 40 NIKKOR Z lenses. That is the manufacturer’s stated system count, not an independently audited count or a guarantee that every lens is in stock in your region. Nikon USA’s Z50II product page

Fujifilm X-M5: a screen-first, small-body candidate
RTINGS describes the X-M5 as a compact interchangeable-lens option and reports a 26MP APS-C sensor and 6.2K open-gate recording. Its key tradeoff is that it has no electronic viewfinder. If you usually compose through a viewfinder, that omission may outweigh the smaller-body appeal; if you are comfortable composing on the screen, it may be a better fit. RTINGS’ compact-camera roundup
How to choose between them
Decide whether you need a viewfinder
A viewfinder gives you another way to compose besides the rear screen. The Z50II has an electronic viewfinder; RTINGS identifies the X-M5’s lack of one as a major compromise. Confirm the viewfinder specification on the exact model you are considering rather than assuming that every mirrorless camera includes one.
Rank #4
- Beginner-Friendly Mirrorless Power: The Canon EOS R100 offers an accessible entry into mirrorless photography with a 24.1MP APS-C CMOS sensor and DIGIC 8 image processor, delivering vibrant, detailed images and smooth video.

From family portraits and daily snapshots to travel landscapes and vlogs, this zoom lens delivers sharp results and smooth autofocus.

Choose a lens system as well as a body
Canon RF/RF-S and Nikon Z are distinct mounts, not interchangeable systems. Adapters can expand options in some cases, but compatibility has limits: Canon excludes EF-M lenses from the R50’s compatible lenses, and Nikon notes restrictions for adapted F-mount lenses. Before buying, make a short list of the lenses you would actually use and verify mount, adapter, and feature compatibility for each.

Think about what you photograph, how you compose, and whether you mainly take stills or also record video. The cited material identifies subject-detection autofocus and a vari-angle screen as R50 strengths noted by Tom’s Guide, while RTINGS reports 6.2K open-gate video for the X-M5. These are different kinds of information, not a direct head-to-head test; check the full specifications and independent comparisons for the specific features that matter to your work.
Compare the whole kit and the exact listing
A body-only listing does not include a lens. A kit listing does, but bundles can differ in the included lens, so inspect the exact contents before comparing prices. Add the lens you need to the body cost, and consider the kit’s carried size. Prices, availability, and bundle contents vary by retailer and region; the sources cited here do not establish a comparable current price for these three cameras.

Manufacturer pages are the right place to confirm mount, sensor, and stated compatibility. Review roundups can help identify tradeoffs or intended audiences, but their recommendations are editorial judgments rather than universal rankings. The information cited here does not provide a controlled comparison of all five leading compact interchangeable-lens cameras, so it cannot support a claim that one model is objectively the best.
