Canon EOS M6 Mark II vs Canon EOS R8: A Hands-On Comparative Review for Photography Enthusiasts

When choosing a mirrorless camera that delivers professional-quality results without breaking the bank, Canon’s EOS M6 Mark II and EOS R8 are two tempting options. Though sharing the Canon heritage, these cameras target distinct segments with notable differences in sensor technology, autofocus systems, ergonomics, and versatility. Having personally tested both extensively across varied photography disciplines, I’m here to guide you through the real-world nuances that differentiate these two models. This way, whether you’re a portrait artist, wildlife hunter, sports shooter, or video creator, you’ll be sure you’re buying the best tool for your specific creative workflow.

Physical size and ergonomic differences between the Canon EOS M6 Mark II and EOS R8.

Introducing the Contenders: Canon EOS M6 Mark II and EOS R8

Before diving deeper, here’s a brief overview:

Sensor Technology & Image Quality: APS-C vs Full Frame

The sensor lies at the heart of any camera’s image quality, dictating resolution, low-light performance, depth of field control, and dynamic range. Here, the M6 Mark II packs a 32.5MP APS-C sensor, while the R8 boasts a 24.2MP full-frame sensor.

Comparing sensor dimensions and how they influence image quality.

What Does This Mean in Practice?

• Resolution: Though the M6 Mark II has a higher megapixel count, the larger sensor area of the R8 means individual photosites are bigger, generally translating to better light gathering per pixel - excellent for low-light and cleaner images at higher ISOs.

• Dynamic Range: In my testing under controlled studio lighting and harsh outdoor highlights, the EOS R8’s full-frame sensor offered superior dynamic range, recovering shadow and highlight details more gracefully without introducing noise.

• High ISO Performance: The R8’s enhanced sensor and newer processor handle ISO sensitivities up to 102,400 (boosted to 204,800) with less noise than the M6 Mark II’s APS-C sensor at its max 51,200 boosted ISO. This is particularly beneficial for astrophotography and night scenes.

• Color Depth: The R8 provides richer gradations and more vibrant color rendition, which I observed in landscape scenes and portrait skin tones.

Summary: If ultimate image quality, particularly in challenging lighting, is your priority, the EOS R8’s full-frame sensor is a clear winner. However, the M6 Mark II’s 32.5MP APS-C sensor still delivers impressively sharp images that suit many enthusiast needs, especially with the right lenses.

Autofocus & Burst Performance: Speed and Accuracy in Action

Autofocus (AF) performance greatly influences your success, whether capturing fleeting wildlife moments or fast-paced sports.

Real-World Autofocus Testing

The R8’s autofocus system impressed me with its vast coverage and precision. Tracking moving subjects felt natural and reliable - even under tricky lighting or fast 3D movement - thanks to the tremendous 1053 AF points and animal eye AF. On the other hand, while the M6 Mark II’s 143-point system is capable and quick for its class, it occasionally struggled with erratically moving wildlife and tighter tracking of sports subjects, particularly in lower light.

Regarding burst shooting, the M6 Mark II’s 14 fps mechanical shutter is quick for an APS-C camera. Meanwhile, the R8’s 6 fps mechanical speed may seem slower but is balanced by an incredible 40 fps electronic shutter mode, ideal for silent shooting and action bursts, though with some rolling shutter considerations on fast motion.

Summary: For wildlife and sports shooters who demand top-tier autofocus tracking and burst capability, the R8 is the more robust performer. The M6 Mark II remains competent but not quite at the same league.

Build Quality and Ergonomics: Handling Your Vision

Physical handling impacts shooting comfort and intuitiveness.

LCD design and user interface layout: tilting vs fully articulated.

Size and Weight

The M6 Mark II is more compact and lightweight (~408 g vs 461 g), appealing for travel and street photographers seeking discretion. However, its rangefinder-style body lacks a built-in viewfinder by default - you must purchase an optional EVF accessory. The R8’s more robust SLR-style body provides a built-in, larger magnification EVF plus weather sealing for use in challenging environments.

Ergonomics and Controls

The R8 features a fully articulated touchscreen, improving usability for vlogging, low-angle, or high-angle shooting. The M6 Mark II’s tilting screen suffices for self-recording but is less flexible.

Control layouts favor the R8’s newer design, with refined button placement and more customizable dials, enhancing quick-access settings changes during fast-paced shoots.

Summary: Ergonomically, the EOS R8 feels like an upgrade for professionals and serious enthusiasts demanding durability and extensive control. The M6 Mark II suits casual users and those prioritizing portability.

Lens Ecosystem: EF-M vs RF Mounts

The available lenses significantly impact your creative options.

• EOS M6 Mark II uses the Canon EF-M mount, with 23 native lenses available. While compact and often affordable, the EF-M lineup lacks some professional-grade optics and telephotos for wildlife or sports.

• EOS R8 uses the RF mount, which benefits from Canon’s newest lens designs offering superior optics, faster apertures, and image stabilization. The RF mount currently supports 37 native lenses and is backward compatible with EF and EF-S lenses via adapters, expanding your options.

Having tested both ecosystems, the RF lens lineup exhibits clearer edge-to-edge sharpness and better control over apertures ideal for portraits and landscapes. The EF-M lenses remain good for general use but can limit versatility at the professional level.

Video Capabilities: Bringing Your Stories to Life

Video quality and features have become essential, whether creating vlogs, short films, or multimedia content.

The R8 offers superior video specs with 4K up to 60p for smoother slow motion and richer video compression codecs, supporting H.265 alongside H.264. Also, the inclusion of a headphone jack lets you monitor audio, critical for professional workflows. The M6 Mark II lacks this headphone port and maxes out at 4K/30p.

Both cameras omit in-body image stabilization, so lens stabilization is vital for handheld video smoothness.

Summary: Video shooters will appreciate the EOS R8’s more advanced 4K capabilities and audio options, making it the logical choice for multimedia creators.
