Check the lens mount and sensor size first. The mount decides which lenses you can add later, and the sensor size affects image quality, body size and lens cost. Then look at the kit lens, the viewfinder, battery and video features. More in the cameras and drones department.
Sensor size
Mirrorless cameras come with several common sensor sizes. Full frame sensors are large and gather the most light. APS-C sensors are smaller, and Micro Four Thirds sensors are smaller still. Smaller sensors mean lighter bodies and lenses, which many travelers like.
| Sensor | Body and lens size | Good for |
|---|---|---|
| Full frame | Larger and heavier | Low light, shallow depth of field |
| APS-C | Mid-size | All-round photos and video |
| Micro Four Thirds | Smallest | Travel, light kits, video |
Lens mounts and the system you are joining
Each maker has its own mount, and some mounts are used by more than one brand. Buying a body is also buying into a system, because lenses made for another mount may not fit without an adapter. Look at what lenses exist for the mount at a range of focal lengths before you commit.
Mirrorless Cameras to compare
Check the lens mount and whether a kit lens is included. The links below sort listings by brand and body.

Body only or kit
A kit includes a starter zoom lens, commonly one that covers a wide to short telephoto range. It lets you start shooting right away. Body-only listings are meant for people with lenses in hand. If a listing says “kit”, check which lens comes with it and that the lens mount matches the body.
Viewfinder, screen and handling
Most mirrorless cameras show the scene through an electronic viewfinder. Check that it exists, since entry-level bodies sometimes skip it and use only the rear screen. A screen that tilts or flips out helps with low angles and video of yourself.
Hold the camera if you can. A grip that feels too small or a body with too few buttons can slow you down. Weather sealing is useful for outdoor shooters but is not found on every body.
Autofocus, video and battery life
Many bodies have autofocus that tracks faces or eyes. For video, check the maximum resolution, the frame rate options and whether there is a jack for an external microphone. Image stabilization in the body helps handheld shots with any lens.
Mirrorless cameras draw more power than older SLRs because of the electronic screen and viewfinder. A spare battery is a good addition, and a USB charging option is handy when you travel.
Memory cards and ports
Check which card type the camera takes, since some use SD and others use faster formats. Two card slots give you a backup. Look for the connections you need, such as USB-C, HDMI and a headphone or microphone port.
Accessories worth planning for
A new camera usually needs a few extras. Add a spare battery, a memory card rated for the video you plan to shoot, and a padded bag or case. A strap that spreads weight across your shoulder makes a heavy lens easier to carry. If you shoot in low light or at night, a small tripod helps keep the camera steady. Check whether the body charges over USB, since that lets a power bank top it up on a trip.
Buying online
Listings for cameras should show the actual body from several angles, including the sensor area, the screen and the mount. Look for a stated shutter count on used bodies, and a list of what is in the box: battery, charger, strap and cap. Match the model number to the maker’s own name for it. Sealed packaging is expected for new items. Read seller feedback and the return policy, and ask for a clear photo of the sensor if the listing shows none.
Frequently asked questions
What is the difference between mirrorless and DSLR?
A mirrorless camera has no mirror box, so the body can be smaller. It shows the picture through an electronic viewfinder or the rear screen.
Does a bigger sensor always mean better photos?
A bigger sensor gathers more light, which helps in dim scenes. Lens quality, skill and lighting also matter a great deal.
Should I buy the body only?
Body only suits you if you already own lenses for that mount. Otherwise a kit with a starter lens is the simpler way to begin.
