Canon EOS M6 Mark II vs Nikon 1 S2: An Expert Face-Off Across a Decade of Mirrorless Innovation

In a camera market where mirrorless systems have surged to the forefront, placing different generations and tiers side-by-side often yields sharp contrasts - and invaluable lessons. Today, I’m diving deep into the Canon EOS M6 Mark II, a 2019 APS-C advanced mirrorless offering, and the Nikon 1 S2, a 2014 entry-level 1” mirrorless that marked a pivotal stage in Nikon’s mirrorless journey. Both share a similar rangefinder-style body design but are aimed at distinctly different users and represent different eras of technology.

Having spent countless hours testing cameras across genres and workflows, I am committed to bringing you a comprehensive, technically informed, yet practical comparison to help clarify what these two models can - and cannot - do for your photography today.

First Impressions: Ergonomics and Build Quality in the Hand

The moment I picked up these cameras side by side, the Canon M6 Mark II reveals itself as a much more substantial and robust tool. Weighing in at 408g and sporting dimensions of 120x70x49mm, the Canon offers a solid grip and a reassuring heft that invites confidence during extended sessions. Its magnesium alloy chassis (though not weather-sealed) delivers durability beyond its entry-level price tag.

In contrast, the Nikon 1 S2 is noticeably compact and lightweight at 190g with a 101x61x29mm body profile. This stripped-down build is excellent for casual carry and street photography where discretion and portability trump ruggedness or heavy-duty usage. The trade-off comes in the form of a more plasticky feel and the absence of a viewfinder - a glaring omission for serious photographers.

Ergonomically, Canon's carefully laid-out controls provide tactile feedback and thoughtful placement, while Nikon’s minimal buttons and no touchscreen limit operational flexibility. If you rely on well-positioned dials and predictable control ergonomics, the Canon clearly leads here.

Sensor Size and Image Quality: Where the M6 Mark II Really Shines

Sensor technology underpins image quality, and here Canon’s APS-C sensor (22.3x14.9mm, 33MP) decisively outperforms Nikon’s 1” sensor array (13.1x8.8mm, 14.2MP). The M6 Mark II’s sensor area is nearly three times larger, admitting more light and therefore delivering greater dynamic range, lower noise at high ISOs, and higher resolution detail.

My hands-on testing in landscape and portrait scenes reveals the Canon’s ability to render nuanced skin tones and textures with superior color depth. The inclusion of an anti-alias filter balances detail and moiré control effectively. Conversely, the Nikon exhibits more noise beyond ISO 800 and struggles to maintain detail in shadows - a direct consequence of its smaller sensor and earlier sensor design generations.

The Nikon 1 system’s severe crop factor (2.7x) means telephoto reach is extended but at a cost to overall image quality and creative depth of field control. This cropping can be a boon for wildlife on a tight budget but will frustrate portraitists seeking creamy bokeh or detail-rich landscapes.

Viewing Experience: LCD and Electronic Viewfinder

The Canon EOS M6 II sports a 3-inch 1,040k-dot tilting touchscreen, striking a great balance for versatile shooting angles and intuitive autofocus point placement. This flexibility is a boon when shooting video, self-portraits (though not marked as ‘selfie friendly’), or low-angle macro shots.

The Nikon 1 S2 also has a 3-inch screen, but its resolution languishes at 460k dots and it is fixed in place without touch capabilities. In practice, this makes composing in bright daylight tricky and navigating menus sluggish.

Crucially, the Canon supports an optional 2.36MP electronic viewfinder (EVF), while the Nikon offers none. For outdoor and action shooters who rely on stable framing, an EVF eliminates glare issues and improves focus accuracy - a non-trivial advantage that the Canon clearly stakes a claim in.

Autofocus Systems: Tracking, Speed, and Accuracy

One of the most exciting technological leaps in mirrorless since 2014 has been autofocus evolution, and here the EOS M6 II comfortably outclasses the older Nikon 1 S2.

Canon’s M6 II features 143 autofocus points utilizing Dual Pixel CMOS AF with phase detection for fast, smooth, and reliable focusing. It supports eye-detection for humans, face detection, continuous tracking, and works admirably well even at relatively low light levels. I specifically tested this capability in portrait and wildlife settings: it kept up pace with moving children and subjects in dynamic cityscapes with minimal focus hunting.

In contrast, the Nikon 1 S2’s 171 contrast/phase hybrid AF points, though numerous, rely more heavily on contrast detection, resulting in slower acquisition and poorer tracking accuracy. It lacks eye AF and animal detection features. While in bright, static conditions it performs adequately, it struggles to maintain focus on erratic or fast-moving subjects such as sports or wildlife.

Burst Rate and Buffer Depth: Capturing Decisive Moments

With sports and wildlife photography demanding high frame rates, the Nikon 1 S2 excels in burst shooting with a blazing 60 frames per second (fps). However, this speed comes with a major compromise: buffer size. The tiny buffer limits continuous shooting duration to short bursts before the camera slows, reducing practical usefulness.

Canon’s M6 Mark II offers an extremely respectable 14 fps with a vastly larger buffer, especially when shooting JPEG + RAW. This translates into sustained high-speed capture sessions ideal for sports, wildlife, or fast-moving street scenes. I found it a solid performer in real-world action, providing flexibility to select the best frames from a series without missing a beat.

Video Capabilities: A Decade Apart in Motion Imaging

Video has become a critical feature even for stills-focused shooters, and here the Canon M6 Mark II firmly steps ahead. It supports UHD 4K recording at 30p using H.264 compression, backed by 120 Mbps data rate for good clarity with manageable files. The inclusion of microphone input makes it suitable for casual videography or vlogging, though the lack of headphone output limits on-the-fly audio monitoring.

In contrast, the Nikon 1 S2 is limited to Full HD 1080p at 60 frames per second with no external microphone port. For anyone serious about video, the older S2 quickly reveals its age. Canon’s M6 II also benefits from modern video features like built-in timelapse and improved in-body processing for smooth exposure transitions.

Lens Ecosystem and Compatibility: How Much Glass Can You Access?

Canon’s use of the EF-M mount provides access to 23 native lenses, spanning wide-angle primes, fast portrait lenses, and versatile zooms in compact form. While not as extensive as Canon's EF or RF DS (full-frame) lines, the EF-M selection is solid for APS-C shooters and compatible adapters allow use of Canon’s full DSLR lens lineup if desired.

Nikon 1’s mount, on the other hand, is limited with just 13 dedicated lenses, focused mainly on compact zooms and primes designed for the smaller sensor - and adapters tend to be cumbersome or unavailable. This limits creative flexibility, especially as mirrorless systems have proliferated lens options dramatically since its launch.

Battery Life, Storage, and Connectivity

Canonical’s LP-E17 battery offers around 305 shots per charge, excellent for an APS-C mirrorless with an EVF option. Nikon’s EN-EL22 is rated at 270, which isn’t far off but comes paired with less power-hungry electronics.

Storage-wise, Canon accepts SD/SDHC/SDXC cards with UHS-II compatibility, offering fast write speeds ideal for high-res bursts and 4K video. Nikon uses microSD - fine for casual video and JPEG shooting but slower and less reliable for intensive RAW capture.

Wireless connectivity with built-in Wi-Fi and Bluetooth on Canon gives seamless image transfer and remote control from smartphones. Nikon requires optional adapters for wireless features, limiting functionality.
