Canon EOS M6 Mark II vs Sony SLT-A77 II: A Hands-On, Expert-Level Comparison for Enthusiasts and Pros

When it comes to choosing your next camera, the sheer number of options on the market can be overwhelming. I’ve spent years putting cameras through their paces - from cushy studio shoots to rugged outdoor adventures - and it’s clear that the right choice isn’t just about specs on paper. Today, I’m diving deep into two tasty options for enthusiasts and professionals alike: the Canon EOS M6 Mark II, a 2019 advanced mirrorless camera, and Sony’s 2014 mid-size DSLR alternative, the SLT-A77 II. At face value, these cameras hail from different design philosophies and eras, but both pack enough features to seriously tempt buyers.

I’ve personally tested both extensively across various real-world scenarios, from portrait sessions to wildlife tracking, so this is a no-fluff breakdown of how they perform practically, plus some honest pros and cons to help you decide which will fit your photography style and budget.

First Impressions: Size, Ergonomics, and Build Quality

Right off the bat, your hands will notice the difference. The Canon M6 Mark II is a rangefinder-style mirrorless camera, which makes it significantly more compact and lighter compared to the heftier Sony A77 II mid-size SLR body.

The Canon measures 120 x 70 x 49 mm and tips the scales at just 408 grams - ideal for traveling light or street shooters who’d rather not lug around clubs for their thumbs. Meanwhile, the Sony A77 II is a bulkier beast at 143 x 104 x 81 mm and a hefty 647 grams, more suited to photographers who prize a solid, traditionally ergonomic grip for long days shooting sports or wildlife. That extra size also translates to more physical controls - a boon for quick settings adjustments without diving into menus.

Speaking of ergonomics, here’s a closer look at their top decks:

The Canon’s minimalistic top plate can feel a bit stripped down at first but packs essentials like a robust shutter mode dial and a front command dial, while Sony’s A77 II offers more dedicated buttons and a top LCD display that shows your settings at a glance - particularly useful if you’re changing settings on the fly in bright conditions.

Build and weather sealing? Sony takes a clear win here. The A77 II features weather sealing to resist dust and moisture, making it suited for harsher environments. The Canon M6 Mark II, however, doesn’t have any official environmental sealing - something to seriously consider if you shoot outdoors frequently.

Sensor and Image Quality: The Heart of Your Shots

The sensor often decides how your photos actually look, so let’s geek out a little. Both cameras utilize APS-C sized CMOS sensors, but with some notable differences worth your attention.

• Canon M6 Mark II: 32.5MP resolution, measuring 22.3x14.9mm
• Sony A77 II: 24.3MP resolution, measuring 23.5x15.6mm

The Canon cranks out a whopping 33MP, the highest resolution I’ve tested in an APS-C Canon to date, which shows in fantastic detail capture and cropping flexibility. The smaller physical sensor size slightly reduces the sensor area compared to Sony’s, but its newer DIGIC 8 processor pushes dynamic range and color rendering to impressive levels, especially at base ISO.

The Sony’s sensor is physically larger with better individual pixel size, leading to slightly improved low-light performance and dynamic range, according to DxO Mark’s ratings (A77 II scoring an 82 overall versus not tested for the Canon). The Sony also edges the Canon for color depth and dynamic range according to lab tests, partly thanks to its sensor design and Bionz X processor - but that gap is narrower than you’d expect given the age difference.

Real-world takeaway? The Canon’s higher resolution makes it more suited to landscapes and studio work where detail is king, while Sony remains solid for low-light shooting with its cleaner high-ISO files and better noise control.

Viewing and Interface: How You See and Navigate Your Shot

You want a great viewfinder or screen to nail focus and composition, and both cameras offer electronic viewfinders (EVFs), but with some differences in experience.

• The Canon M6 Mark II sports a 3-inch tilting touchscreen LCD with 1.04M dots. It’s crisp, bright, and a touchscreen means you can tap to focus or quickly navigate menus. Its optional EVF (sold separately) offers 2.36M-dot resolution.
• The Sony A77 II has a fully articulated 3-inch LCD with 1.22M dots, but no touchscreen (a sore point if you’re used to tapping). Its built-in EVF is also 2.36M-dot, but benefits from higher magnification (0.73x vs. Canon’s 0.5x equivalent), giving a more immersive view.

I personally prefer Canon’s touchscreen for studio setups or casual shooting where you want quick retouching on the fly. However, the Sony’s built-in EVF feels more “optical-like” and less laggy, which is appreciated when tracking fast action.

In terms of interface, Sony’s DSLR heritage shines with dedicated dials and buttons, which pros will appreciate for speedy, tactile control under pressure. Canon’s menu system is intuitive but requires a bit more menu diving for some advanced features.

Autofocus Systems: Speed, Accuracy, and Tracking

Arguably the most important feature for many photographers, autofocus performance defines how reliably you can grab sharp shots in any setting.

The Canon M6 Mark II employs an on-sensor Dual Pixel CMOS AF system with 143 phase-detection points spread across a wide area of the sensor. This provides smooth, reliable autofocus with excellent eye detection capabilities - particularly helpful for portrait shooters or street photographers requiring fast face and eye tracking.

Sony’s A77 II relies on a hybrid phase detection and contrast detection system with 79 AF points and 15 cross-type points - a bit dated but still capable, especially in good light. Its phase detection autofocus is fast, with excellent tracking for moving subjects, thanks to Sony’s translucent mirror technology (which lets the AF system work during continuous shooting).

During my wildlife and sports photography tests, Sony’s tracking held up better for erratic subjects at high frame rates, while Canon’s eye detection proved unbeatable for portraits and street portraits, nailing focus with ease even in challenging lighting.

Continuous Shooting and Buffer Depth

For sports and wildlife shooters, burst speed and buffer depth are essential to capturing the decisive moment.

• Canon M6 Mark II delivers a blistering 14fps burst with autofocus and exposure tracking, impressive for a mirrorless camera in this category.
• Sony A77 II shoots 12fps continuously, which on paper is slightly slower - but its translucent mirror allows for full-time AF tracking during bursts, giving practical advantages in sustained sequences.

This makes the Canon slightly better for fast action when you want sheer speed, but Sony may win in reliability for longer shooting bursts.

Image Stabilization: Do You Need It In-Body?

Sony’s A77 II sports sensor-based image stabilization, rated around 4.5 stops of shake reduction, which plays a huge role in handheld shooting especially with telephoto lenses or in low light. Canon’s M6 Mark II relies on lens-based IS and, crucially, its body lacks in-body stabilization. This means you’d either need a stabilized lens or risk some blur when shooting handheld at slow shutter speeds.

This is a major consideration if you often shoot walk-around or wildlife scenarios where you’re constantly on the move without tripods.

Video Capabilities: Not Just a Still Camera

Video performance is an increasingly important feature, especially for hybrid shooters.

• The Canon M6 Mark II offers clean 4K UHD recording at 30p with H.264 codec, full control over exposure modes, and an external microphone input but no headphone jack. Its clean HDMI output indicates it is a respectable vlogging and casual filmmaking tool.

• Sony’s A77 II tops out at 1080p Full HD, but impressively supports 60p frame rates and multiple codecs including AVCHD and XAVC S, with an external mic port but again no headphone jack.

If video is a priority, Canon’s 4K is a standout feature here. Note, neither camera offers in-body stabilization for video, so stabilization depends on lenses or external gimbals.

Lens Ecosystem and Compatibility

Lens options can make or break your camera system, especially for professionals.

• Canon EOS M6 Mark II uses Canon’s EF-M lens mount, which is still somewhat niche with around 23 native lenses available - mostly compact primes and zooms. However, Canon offers an adapter, allowing the use of its extensive DSLR EF/EF-S lens collection, which grants access to hundreds of professional optics.

• Sony A77 II uses the Sony/Minolta Alpha mount, which enjoys a mature ecosystem with 143 lenses, covering everything from consumer zooms to professional telephotos and macro lenses. This gives Sony a huge leg up for those who want a broad and affordable lens selection out of the box.

If you already own Canon lenses, the M6 Mark II offers a great bridge to mirrorless without losing that investment, while Sony’s mount is more extensive but requires DSLR-sized glass.

Battery Life and Storage

Battery longevity can be a pain point, so here’s the rundown:

• Canon claims around 305 shots per charge using the EVF, typical for mirrorless cameras that tend to drink power faster.
• Sony A77 II impresses with roughly 480 shots, a significant boost for day-long sessions without swapping batteries.

Both cameras accept SD cards, but Canon supports UHS-II cards for faster buffer clearing and data transfer, while Sony supports Memory Stick Pro Duo and SD cards (mainly UHS-I).

For travel photographers or those in the field, Sony’s battery advantage could be a significant factor.
