Canon EOS M10 vs Panasonic Lumix G100: An In-Depth Hands-On Mirrorless Comparison

Choosing your next camera can feel like navigating a maze of specs, acronyms, and features - especially when budgets are tight but demands remain high. Today, I’m diving deep into two entry-level mirrorless cameras that have garnered attention from enthusiasts and semi-pros alike: the Canon EOS M10 (launched in 2015) and the Panasonic Lumix G100 (introduced in 2020). Though similar in price point and aimed at the beginner-friendly segment, these cameras offer distinct philosophies in handling, image quality, and versatility.

Having personally tested thousands of cameras over the years across multiple genres - from wildlife safaris to night sky timelapses - I’ll bring you a comprehensive, practical comparison grounded in real-world shooting, side-by-side technical insights, and usability considerations. By the end, you’ll have a clearer perspective on which model might best serve your photography style and creative ambitions.

Getting a Feel: Size, Ergonomics, and Controls

First impressions matter - and that includes how the camera feels in your hands during a day-long shoot. Ergonomics not only affect comfort but impact your shooting efficiency and how naturally intuitive the controls become.

The Canon M10 is a compact rangefinder-style mirrorless camera, almost pocketable in size with dimensions of 108x67x35mm and weight at just 301 grams (body only). It’s noticeably smaller and slimmer compared to the Panasonic G100, which takes a more traditional SLR-style stance with bulkier handling at 116x83x54mm and weighs 352 grams.

The M10 feels quite minimalistic with a squat grip - great for those prioritizing portability but it lacks the substantial clubs-for-thumbs grip shape that larger cameras offer. Meanwhile, the G100, with its beefier build, offers more substance to hold onto, which can be invaluable for longer shooting sessions or using heavier lenses.

The control layout shows the M10 leans heavily into simplicity, with fewer dials and buttons. It features basic mode dial and a shutter speed dial but no dedicated exposure compensation dial, which may be a slight step back for more hands-on shooters. The Panasonic G100 ups the ante with more dedicated controls, including a function button and an exposure compensation dial – a nod to the photographer who wants finer realtime control without menu diving.

In short, if you prize ultra-portability and selfie-friendly design, M10 could win. But for tactile engagement and a camera that grows with your skills, the G100’s ergonomics shine brighter.

Sensor and Image Quality: The Heart of the Camera

At the core, the sensor size, resolution, and underlying technology determine much of your camera’s image potential - from low-light prowess to detail capture.

The Canon M10 sports an 18MP APS-C sized CMOS sensor measuring 22.3 x 14.9 mm. Canon’s APS-C sensors, generally about 1.6x crop factor, capture a sizeable amount of light with decent dynamic range and color fidelity. The Canon DIGIC 6 processor, while dated, still delivers respectable image processing for photo clarity and color rendering.

The G100 uses a smaller 20MP Micro Four Thirds sensor (17.3 x 13mm), roughly half the area of Canon’s APS-C. As this relates to light-gathering ability, the smaller sensor usually means slightly lower dynamic range and high-ISO noise performance. But Panasonic’s newer sensor tech and image processing do help punch above its weight.

In side-by-side image comparisons, the M10 tends to have a slight edge in dynamic range and color depth, particularly at base ISO, offering richer skin tones and smoother gradient transitions. Meanwhile, the G100 delivers punchy colors with more accurate whites, likely benefiting from Panasonic's continual improvements in color science.

Both cameras have anti-aliasing filters to reduce moiré but at a tradeoff to absolute sharpness, so fine detail is good without excessive artifacting. The M10’s native ISO spans 100–12800 (expandable to 25600), while the G100 natively is ISO 200–25600 with a downscaled ISO 100; this slightly higher base ISO on the G100 may affect the cleanest images in bright light.

If your priority is the best image quality in crisp detail and skin tone rendering, Canon’s APS-C sensor holds a slight advantage thanks to its larger size and mature processor.

LCD Screens and Viewfinders: Watching What You Shoot

For mirrorless shooters, the rear LCD and electronic viewfinder (EVF) are your window to composition.

Canon’s M10 offers a 3-inch tilting LCD with 1,040k dot resolution. It’s touchscreen-enabled and selfie-friendly – ideal if you vlog or take self-portraits. However, it lacks a built-in EVF entirely, which might frustrate anyone who prefers eye-level framing in bright daylight.

Panasonic’s G100 steps up with a fully articulated 3-inch touchscreen boasting a sharper 1,840k dots and, crucially, a built-in EVF with 3,680k dot resolution and 100% coverage. This comprehensive viewing setup is a boon for composition flexibility, especially outdoors or for manual focus precision.

The higher resolution LCD and inclusion of an EVF on the G100 not only assist in composition but also in assessing focus and exposure more confidently in all lighting.

Autofocus: Speed, Accuracy, and Tracking in Real Life

Autofocus systems can make or break shots in action photography or unpredictable moments.

Both cameras sport 49-point AF systems with contrast-detection focusing, supplemented by face-detection to help nail portrait shots. Although neither boasts the latest phase-detection hybrid AF that’s now common on mid to high-end mirrorless models, these systems still serve casual shooters well.

The Canon M10 uses the DIGIC 6 processor’s ability to rapidly analyze contrast shifts, which gives it relatively decent AF speed for static and moderately paced subjects. The touchscreen AF also aids in pinpointing focus.

The Panasonic G100 relies solely on contrast detection (no phase-detect), yet benefits from more modern AF algorithms and the improved processing power to achieve faster AF speeds overall. It also gained focus bracketing and stacking capabilities that appeal to macro photographers or those doing focus stacking for extra depth.

For burst shooting, the M10 shoots at 4.6fps, which is workable but not stellar for sports or wildlife chasing fast action. The G100 improves on this with a 10fps burst, doubling the capture capability and increasing the chance of nailing those decisive moments.

Flash and Low-Light Performance

Entry-level mirrorless cameras usually pack decent built-in flashes but limited external flash capabilities.

Canon’s M10 includes a built-in flash with a 5-meter range at ISO 100. It supports auto, on, off, and slow sync flash modes but lacks a hot shoe for external flashes, limiting off-camera lighting options.

The G100 provides a built-in pop-up flash with a 3.6m range at ISO 100 and supports more flash modes like red-eye reduction. Importantly, it offers a hot shoe for external flash units - a significant plus if you plan to delve into studio or event photography on a budget.

Regarding low light, the M10’s larger sensor and slightly lower base ISO translate to better noise control and dynamic range, so expect cleaner night shots. The G100’s smaller sensor is noisier beyond ISO 1600, which is typical for Micro Four Thirds but can be partially mitigated with Panasonic’s noise reduction algorithms.

Video Capabilities: Who Covers What?

The boom in video content means many users expect decent video features even from entry-level cameras.

The Canon M10 limits itself to full HD 1080p recording up to 30fps with MPEG-4 and H.264 codecs. No 4K support here, and no external mic input, which restricts audio quality options for serious vloggers or filmmakers. The lack of in-body image stabilization means you’ll depend on lens stabilization or handheld finesse.

The Panasonic G100, by contrast, supports 4K video capture at up to 30fps with a bitrate of 100 Mbps, giving sharper footage and more flexibility in post-production. It also offers Full HD recording up to 120fps for smooth slow-motion clips. A headphone port is absent, but it does come with a microphone input jack, vital for capturing good audio.

One unique G100 advantage is its V-Log L profile option, providing flat color for grading, and advanced video autofocus with subject tracking. This makes Panasonic a clear winner if video content is part of your workflow.

Lens Ecosystem and Compatibility: Where Do Your Glasses Land?

A camera is only as good as the lenses you can mount on it.

The Canon M10 utilizes the Canon EF-M mount, which, per the specs, has around 23 native lenses. While fairly limited compared to Canon’s EF and EF-S DSLRs, you can use an adapter to access more Canon EF glass if you’re willing to carry adapters and accept some bulk or autofocusing limits.

The Panasonic G100 builds on the Micro Four Thirds mount, one of the richest ecosystems around with over 100 native lenses from Panasonic, Olympus, and third-party makers. From fast primes to super telephotos and specialized macro lenses, the available options are impressive and often more affordable.

So, if you plan to grow your lens collection or want versatility across genres (wildlife, macro, portrait), the G100’s lens lineup is substantially more attractive.

Battery Life and Storage: Practical Daily Use

Long shooting sessions demand sufficient battery life and flexible storage.

Canon M10’s LP-E12 battery rates around 255 shots per charge, which is on the modest side – expect to carry spares if you plan extended shooting (or use power banks with USB charging).

Panasonic’s G100 is rated slightly higher at 270 shots on its battery, but similarly, not impressive by modern standards. Likewise, both use single SD card slots compatible with SD/SDHC/SDXC cards, with the G100 supporting faster UHS-I cards, beneficial for video.

If you are an on-the-go traveler or event shooter, plan accordingly with extra batteries for either camera.

Build Quality and Weather Resistance

Both the Canon M10 and Panasonic G100 are compact, entry-level mirrorless cameras with predominantly plastic bodies and no environmental sealing. Neither is weatherproof, dustproof, or shockproof. In rough outdoor or inclement weather, you’ll need protective cases or umbrellas.

The Panasonic G100’s slightly more rugged design and larger grip may inspire more confidence in tougher conditions, but neither camera is a professional-grade build.
