Canon EOS M6 Mark II vs Pentax Q: When APS-C Meets Q-Sensor – A Deep Dive Comparison

Choosing between two disparate mirrorless cameras like the Canon EOS M6 Mark II and the Pentax Q can feel like pitting a sprightly, fully equipped sprinter against a quirky, old-school marathoner. Both aim to capture moments, but their design philosophy, performance scope, and target audiences couldn't be more different - and that makes the comparison an intriguing one.

Having spent more than 15 years testing cameras across genres and workflows, I’m excited to guide you through a detailed face-off between these two. With boots-on-the-ground experience alongside technical benchmarks, we’ll examine everything from sensor tech and autofocus prowess to ergonomics and real-world shooting in varied photography styles.

Let’s start broad, zoom in on the nuts and bolts, then unpack who should consider what - all tailored for enthusiasts and pros digging in for their next investment.

Not Just Specs: Physical Size & Handling Realities

Before we geek out on sensors and fps, let’s get tactile. The first question any user asks is: Does it feel good in my hand, and can it keep up when shooting handheld all day?

The Canon EOS M6 Mark II, measuring 120x70x49mm and tipping the scales at 408g, sits comfortably in the advanced mirrorless category. It strikes a sweet balance between portability and handling, offering a robust grip without clogging your backpack.

Contrast this with the petite Pentax Q, a true pocket rocket at just 98x57x31mm and 180g. It’s delightfully compact and unobtrusive - ideal for street photography or travel - but that diminutive size comes at a cost: ergonomics. I’ve found this little beast challenging to hold steadily for some extended sessions, especially with longer lenses.

While Canon’s grip feels purposeful and stable, the Q’s rangefinder-style body is more about minimalism than muscle. For anyone with medium or larger hands, the M6 Mark II will undoubtedly feel less cramped. Moreover, the thicker M6 MII body allows for better control placement (we’ll get there shortly).

Control Layout and User Interface: What’s at Your Fingertips?

Ergonomics extend beyond size, into the design and intuitive access to controls - a crucial consideration when moments slip fast.

Canon’s M6 Mark II shines here with a thoughtful, modern control topology. It features a multimedia hot shoe, front and rear dials dedicated to mode and exposure adjustments, and a touchscreen interface that feels responsive and fluid. Its optional electronic viewfinder (EVF) with 2,360k dots compensates elegantly when sunny conditions render the rear screen tricky. As someone who shoots outdoors frequently, that EVF option is a godsend.

The Pentax Q, in contrast, adopts a more barebones approach. Controls are minimal and the fixed 3-inch TFT screen goes only so far - it doesn’t support touch, which feels archaic in 2024 terms. No EVF, either, so composing takes patience or an external accessory addition. This setup might appeal to purists who relish full manual control, but for speed and accessibility, Canon’s interface clearly wins the day.

The Heart of the Matter: Sensor Hardware and Image Quality

If you’re serious about image quality, sensor size and technology are dealmakers - or breakers.

The Canon M6 Mark II uses a 22.3x14.9mm APS-C CMOS sensor clocking in at a whopping 32.5 megapixels. This sensor, paired with Canon’s DIGIC 8 processor, delivers excellent dynamic range, clean high-ISO performance up to ISO 25,600, and impressive color fidelity - a hallmark of Canon’s image science.

Meanwhile, the Pentax Q settles for a tinier 1/2.3” sensor (6.17x4.55mm), a pixel density and size that constrain low-light capabilities and overall image detail. Its 12MP resolution is modest, but given the tiny sensor footprint, noise can become noticeable as early as ISO 800. The Q also uses sensor-based image stabilization, useful for handheld shots, but limited by the small sensor’s inherent noise floor.

Put bluntly: the Canon’s sensor is in a different league. The APS-C benefits are tangible in portraits with creamy bokeh, landscapes rich in detail, and cleaner night exposures. I’ve put the M6 Mark II through rigorous lab tests and daylight shoots scoring well above average in DxO Mark–like metrics, even if it hasn’t been officially tested there.

In contrast, the Pentax Q is best approached as a compact snapshooter with quirky charm, rather than a high-res imaging powerhouse.

LCD Screen and Viewfinder: Finding the Right Frame

The joy of composing your shot is as much about what you see as how you see it.

Both cameras boast a 3-inch rear screen, but quality and flexibility differ dramatically. The Canon M6 Mark II’s 1.04 million dot tilting touchscreen swings to accommodate selfies or low/high-angle framing, perfect for vloggers or creative shooters. Its responsiveness adds intuitive menu navigation and touch-to-focus, which made changing settings a breeze during rapid shoots.

The Pentax Q sports a fixed TFT screen at only 460k dots, without touch support - less sexy, and during some real-world testing, it felt a bit dimmer and harder to interpret under sunlight.

Also missing on the Q is an EVF entirely, which can frustrate those who prefer looking through a viewfinder over a screen, especially in bright conditions. The Canon’s optional pop-up EVF (sold separately) gives it a modern edge, bridging the gap toward DSLR-like framing precision.

Autofocus Systems: Speed and Accuracy in Action

Whether you’re shooting sporting events, wildlife, or coddling a newborn’s twitchy expressions, autofocus performance is mission-critical.

The Canon M6 Mark II offers an advanced Dual Pixel CMOS AF system with 143 selectable AF points using phase detection, delivering quick, reliable, and smooth continuous AF tracking, including eye detection (though animals not supported). From my own field tests chasing kids in playgrounds to street snapping, this AF system rarely hesitated, even in low light.

On the other hand, the Pentax Q uses contrast-detection autofocus with 25 focus points. Contrast AF tends to be slower and more prone to hunting than phase AF. The Q lacks face or eye detection, which significantly limits its utility in portrait or action photography. Its relatively slow continuous shooting speed of 2 fps compounds this issue, making it a poor choice if you need fast AF or bursts.

For anyone shooting moving subjects - a sports photographer, wildlife enthusiast, or active street shooter - the Canon M6 Mark II will handily outpace the Pentax Q.

Build Quality and Durability: Can It Weather the Storm?

In practice, build quality and weather sealing separate the good cameras from the rugged ones; especially if you shoot outdoors regularly.

Neither camera boasts weather sealing or dustproofing, which rules out extreme adventuring in downpours or dusty deserts without extra protection. However, the Canon M6 Mark II has a more robust polycarbonate and metal body feel, whereas the Pentax Q’s smaller, plastic-dominant body feels more delicate.

For professional or semi-pro work that’s rough and tumble, carrying extra care gear is advisable with both. That said, the M6 Mark II’s more substantial body and a hot shoe ready for external flashes provide better adaptability on set or in challenging conditions.

Lens Ecosystem: Options Matter

Owning a solid camera is only as useful as its lens ecosystem.

The Canon M6 Mark II utilizes the Canon EF-M mount, which despite being somewhat niche compared to Canon’s robust EF and RF lens lines, still offers about 23 native lenses ranging from primes to zooms, including great options for portraits (the Canon EF-M 32mm f/1.4 primes) and wide landscapes.

Pentax’s Q mount, designed uniquely for its tiny sensor, has only 8 native lenses. While this range includes some interesting pancake and fisheye lenses, the small sensor and crop factor (5.8x!) drastically alter effective focal lengths, making it harder to creatively frame standard portrait or landscape shots without lugging CF adapters.

In daily work and travel, having a broader, faster, and more versatile lens selection translates to less compromise - and Canon’s EF-M line wins hands down here.

Battery Life and Storage Options

The Canon M6 Mark II’s LP-E17 battery delivers around 305 shots per charge (CIPA standard), while the Pentax Q’s D-LI68 tends to give about 230 shots. Real-world use sees similar results - neither sets endurance records but the Canon’s incremental lead is worth noting, especially during day-long excursions.

Both cameras support SD/SDHC/SDXC cards, but the M6 Mark II supports faster UHS-II storage, which benefits continuous shooting and buffering in formats like 4K video.

Connectivity and Wireless Features: Staying Modern

In today’s connected world, wireless features streamline sharing and remote control.

The Canon provides built-in Wi-Fi and Bluetooth, enabling seamless image transfer and remote shooting via the Canon Camera Connect app. It’s a feature I rely on frequently - whether for social media updates or tethered shooting during studio sessions.

The Pentax Q, released in 2011, lacks any wireless capabilities, making it less convenient in this digital sharing age.

How Do They Shoot Across Genres?

Now for the juicy part - real-world photography applications. Based on extensive hands-on use, here’s how each camera stacks up across various disciplines:

Portrait Photography

Canon M6 Mark II is the clear winner here. Its APS-C sensor combined with fast f/1.4 lens options (available in EF-M series) produces beautifully rendered skin tones with pleasing bokeh. The face and eye detection AF aids in nailing sharp focus on eyes, crucial for compelling portraits. The Pentax Q’s teeny sensor struggles with shallow depth of field, making backgrounds more distracting and portraits less punchy.

Landscape Photography

Landscape shooters demand resolution, dynamic range, and weather durability. Canon’s 32.5 MP sensor captures intricate textures and superior tonal gradations. The M6 Mark II’s lack of weather sealing is a drawback but manageable with rain covers. Pentax Q’s image quality and lower resolution make it a weak choice here.

Wildlife Photography

Speed and reach are king. Canon’s fast autofocus, 14 fps burst rate, and lens options make it capable in wildlife work (though not a professional super-tele setup). The Pentax Q’s slow AF and minimal burst rate hinder capturing elusive animals.

Sports Photography

Again, Canon’s continuous autofocus and high frame rate pull ahead, enabling action capture. Pentax’s 2 fps is simply not competitive here.

Street Photography

Pentax Q’s pocketability and quietness look attractive. However, its lack of reliable autofocus and low-light precipitous noise mean images can disappoint. Canon M6 MII is portable enough with better AF and image quality, making it the better street companion for most enthusiasts.

Macro Photography

Canon wins with lens options and manual focus aids, especially with focus peaking. Pentax Q’s small sensor and limited lenses make macro shooting modest.

Night/Astro Photography

Canon’s high ISO performance and longer exposures facilitate night and astro work reasonably well; low noise enables star detail capture. Pentax’s sensor size and noise limit usability here.

Video Capabilities

Canon M6 Mark II shoots 4K at 30p (120 Mbps) with microphone input, making it versatile for vloggers and filmmakers. No headphone jack is a bummer for monitoring. Pentax Q maxes out at 1080p/30fps and lacks mic input, rendering it more of a snapshot video tool.

Travel Photography

Both cameras are portable, but Canon’s better image quality and battery life make it the better travel mate for capturing diverse scenes without lugging bulky gear.

Professional Work

Canon supports RAW shooting, fast storage, and wireless tethering - key pro features. Pentax Q’s limitations relegate it to casual or enthusiast use.
