The Canon EOS M100 is a genuinely small interchangeable-lens camera built around a 24.2-megapixel APS-C sensor. It was designed for beginners moving beyond a smartphone rather than photographers who wanted extensive physical controls, a viewfinder or professional video features.
Its age does not prevent it from producing attractive photographs. The sensor, Canon colour and Dual Pixel autofocus remain useful, while the light body is easy to carry. The larger question is not whether the EOS M100 can take good pictures—it can—but whether buying into the discontinued EF-M system makes sense for your needs.
Short verdict: the EOS M100 can still be a good low-cost travel, family or beginner camera when bought used with a suitable lens. It is a weaker choice for anyone planning to build a long-term system, record serious video, photograph through a viewfinder or develop into fast action and wildlife photography.

Image quality: much better than its size suggests
The 24.2MP APS-C sensor is the main reason to consider the EOS M100. It is much larger than a typical phone sensor and can capture detailed images with natural background separation when paired with the right lens. Resolution is sufficient for large prints, cropping and normal commercial or stock use when the photograph is properly exposed and focused.
Canon’s JPEG processing produces pleasant colour and convincing skin tones without demanding immediate editing. RAW files preserve more information and give greater control over white balance, shadows, highlights and noise. Beginners can therefore start with JPEG and move to RAW when they want more control.
Low-light results depend heavily on the lens. The compact EF-M 15–45mm kit zoom is convenient, but its modest maximum aperture forces the camera to raise ISO as light fades. A brighter prime lens can deliver cleaner indoor images and stronger background blur. Our guide to understanding camera ISO explains why more sensitivity also means more visible noise and less fine detail.
The EOS M100 has no sensor-shift stabilisation. It can benefit from lenses that include optical Image Stabilizer technology, but an unstabilised lens receives no physical correction from the body. Stabilisation also cannot freeze a moving child, pet or person; for moving subjects, shutter speed remains the critical control.
Autofocus and everyday performance
Dual Pixel CMOS AF gives the EOS M100 smooth, decisive focusing across much of the frame. Touching a subject on the rear screen is often the quickest way to select focus, and face detection makes the camera approachable for portraits and family photographs. It feels far more responsive than older entry-level mirrorless cameras that relied mainly on contrast detection.
Continuous autofocus is useful for ordinary movement, but the camera is not designed for demanding sport or wildlife. Its maximum 6.1 fps burst uses fixed focus; with continuous autofocus the rate is closer to 4 fps. Tracking also lacks the sophisticated subject recognition found in newer Canon RF bodies.
For holidays, street scenes, food, portraits and daily life, the performance is adequate. For birds in flight, field sports or erratic action, both the autofocus system and the small control layout become limiting.
A camera built around the touchscreen
The EOS M100 keeps buttons and dials to a minimum. Most settings are changed through Canon’s touchscreen interface, which is clear and responsive. This makes the camera accessible to someone arriving from a phone, but photographers who frequently adjust shutter speed, aperture, ISO and autofocus settings may find the body too simplified.
The 3-inch screen tilts upward through 180 degrees for self-portraits, low-angle compositions and filming yourself. It does not articulate sideways or tilt down significantly, but its upward movement is useful for the audience the camera was designed to serve.
There is no built-in electronic viewfinder and no connection for an optional one. In bright sunlight, composing on the rear screen can be less comfortable than using a viewfinder. This is a fundamental design choice, not an accessory that can be added later.
Video: useful Full HD, but no 4K
The EOS M100 records Full HD video at up to 60 frames per second. Dual Pixel AF provides smooth refocusing, and the flip-up screen helps when the camera is facing its operator. For family clips, travel memories, simple tutorials and social-media video, the results can be perfectly usable.
There is no 4K recording and no external microphone socket. Audio therefore comes from the built-in microphones, with limited options for improving it. The screen also flips above the body, where it can be obstructed by accessories mounted near the top of the camera.
Anyone buying primarily for video should treat these as meaningful restrictions. The EOS M100 is best understood as a small stills camera that can record occasional Full HD footage, not as a modern content-creation system.
The discontinued EF-M system explained
The EOS M100 uses Canon’s EF-M mount. Canon has ended development of the EOS M camera line and shifted its mirrorless future to the RF mount. That does not make existing EF-M cameras and lenses stop working, but it means buyers should not expect new Canon EF-M bodies or lenses.
The existing lens range covers common needs and contains several genuinely compact options. The EF-M 15–45mm kit zoom is convenient for general use, the EF-M 22mm f/2 is an excellent small everyday prime, and wider, longer and macro choices can be found on the used market. Third-party EF-M lenses also expand the selection.
Canon EF and EF-S DSLR lenses can be attached with an EF–EOS M adapter while retaining electronic aperture control and autofocus. This increases compatibility considerably, but larger DSLR lenses reduce the size advantage of the tiny M100 body.
RF and RF-S lenses do not fit the EOS M100. EF-M lenses also cannot be transferred to Canon’s current RF bodies. This separation is the central buying decision: the EOS M100 makes sense as an inexpensive, self-contained kit, but it is not the ideal foundation for a system you intend to expand for many years.
Portability, connectivity and battery
At roughly 302g including battery and card, the EOS M100 is easy to place in a small bag and light enough to carry throughout the day. Combined with a compact EF-M lens, it provides a real advantage over larger DSLRs and many full-frame systems.
Wi-Fi, Bluetooth and NFC support image transfer and remote connection through Canon’s app. Wireless behaviour can depend on the phone, app version and operating system, so it is sensible to confirm compatibility rather than buying the camera solely for connectivity.
The LP-E12 battery is small, and battery life is modest. Screen use, wireless connections, image review and video recording all reduce endurance. A genuine or reputable spare battery is one of the most useful accessories for travel.
What you need besides the camera
- An EF-M lens: check used listings carefully because some are body-only.
- An SD card: a reliable card from an established manufacturer is more important than chasing the highest advertised speed.
- A spare LP-E12 battery: useful for days away from a charger.
- An EF–EOS M adapter: only if you intend to use Canon EF or EF-S DSLR lenses.
- A small bag or protective case: the compact size is worth preserving rather than surrounding the camera with oversized accessories.
Who is the Canon EOS M100 for?
The camera suits beginners who want better image quality than a phone without carrying a large body. It also works well as a lightweight holiday camera, a simple family camera or an inexpensive second body for someone who already owns EF-M equipment.
It is less suitable for photographers who rely on a viewfinder, regularly change exposure settings, need an external microphone, photograph fast action or want a clear upgrade path. The Canon EOS M50 adds a viewfinder and more traditional camera controls while remaining within the same discontinued EF-M system.
Buying a used EOS M100
Check the touchscreen across its entire surface, the tilt mechanism, memory-card slot, battery compartment, lens mount, flash and USB connection. Test autofocus with a known lens and inspect the sensor for scratches or stubborn marks. Confirm that the correct charger and LP-E12 battery are included.
Look at the complete package rather than the body price alone. A clean camera supplied with the EF-M 15–45mm lens, battery and charger may represent better value than a cheaper body requiring each item separately. Availability of the specific lenses you want should be checked before purchase.

The 30-second decision
Buy it if you want a genuinely small, inexpensive camera for still photography, are satisfied with the existing EF-M lenses and find a complete used kit at a good price.
Skip it if you need a viewfinder, 4K video, a microphone input, advanced action tracking, in-body stabilisation or a lens system with an active future.
The price rule: the EOS M100 should be inexpensive enough to justify entering a discontinued system. If a newer RF-mount beginner camera costs only a little more, the newer system is normally the better long-term purchase.
Final verdict
The Canon EOS M100 is simple, light and capable of producing photographs that are far better than its small body might suggest. Its 24.2MP sensor, Canon colour, responsive touchscreen and Dual Pixel autofocus still make it pleasant for travel, portraits and everyday photography.
Its value now depends on realistic expectations. It lacks a viewfinder, 4K, IBIS, extensive controls and an external microphone connection, while the EF-M mount has no development path. Bought cheaply as a complete compact kit, it can still be an enjoyable camera. Bought as the beginning of an ambitious future system, it is difficult to recommend.
