A Tale of Two Cameras: Canon SX720 HS vs. Sony A7R II - Compact Convenience Meets Professional Precision

When faced with the challenge of choosing between the Canon PowerShot SX720 HS and the Sony Alpha A7R II, you're essentially deciding between two wildly different beasts under the same photography umbrella: one a portable superzoom pocket rocket, the other a full-frame professional mirrorless powerhouse. Both bear the Canon and Sony badges, but their ambitions diverge dramatically - and so do their capabilities, handling, and workflows.

Having spent thousands of hours behind camera grips, pushing gear through demanding tests, I've learned that the best camera rarely comes down to megapixels alone (spoiler: the A7R II packs 42 MP against the SX720’s 20) but rather how the tool matches your vision, shooting style, and budget. So, buckle up. Let's peel back the specs, look under the hood, and - most importantly - see how they hold up in real life across every major photography domain.

First Impressions: Size, Ergonomics, and Build Quality

Imagine comparing a sprinter to a marathoner; that's roughly what we face when looking at these two. The Canon SX720 HS is a compact superzoom designed for convenience, cramming a 40x zoom into a pocket-friendly chassis. Meanwhile, the Sony A7R II is a beefy, mirrorless full-frame camera built for uncompromising image quality and professional control.

When placed side by side, the Canon SX720 HS measures a dainty 110 x 64 x 36 mm and tips the scales at a mere 270g. It fits nicely in a jacket pocket - perfect for strolling the streets or traveling light. The Sony A7R II is substantially larger and heavier at 127 x 96 x 60 mm and 625g, reflecting its robust mid-sized body with room for interchangeable lens mount and a hefty sensor.

Build quality echoes these distinctions. The Canon’s plastic compact body feels well put-together but lacks weather sealing, dustproofing, or any rugged protections. Good for casual use, less ideal for challenging environments. Conversely, the Sony A7R II features a magnesium alloy frame with extensive weather sealing - a camera you’d trust hiking through a drizzle or a dusty landscape.

The Canon’s control layout is minimalistic with essential buttons and a fixed 3-inch screen - more on the screen later - whereas the Sony A7R II boasts a thoughtfully milled grip, numerous customizable buttons, a top panel status screen, and a refined shutter release that feels as serious as its price tag.

If you’re prioritizing portability and shooting spontaneity, Canon’s offering charms with its diminutive frame. For photographer-types who value tactile controls and durability, the Sony announces its presence instantly.

Sensor Size and Image Quality: The Heart of the Matter

Canon’s SX720 crams a 1/2.3-inch type BSI-CMOS sensor with 20.3 megapixels - a common size for compact superzooms - while the Sony A7R II proudly houses a 35.9 x 24mm full-frame BSI-CMOS sensor with a whopping 42.4 MP resolution.

The sensor size difference alone is monumental: 861.6 mm² (Sony) vs. 28.07 mm² (Canon) - that’s roughly 30 times larger in sensor area for the Sony. This translates directly into vastly superior image quality potential for the A7R II, thanks to:

• Better low-light performance
• Wider dynamic range
• Shallower depth-of-field control
• Higher resolution detail rendering

In my extensive testing, the A7R II’s sensor shines in all conditions, resolving intricate details in landscapes, maintaining skin tone fidelity in portraits, and preserving shadows and highlights remarkably well. Its lack of an anti-aliasing filter sharpens details further - making pixel-peepers very happy indeed.

On the other hand, the Canon SX720 HS offers respectable daylight images suitable for casual sharing or family albums. It’s not designed for large prints or pixel-level cropping. Noise becomes prominent above ISO 800, and dynamic range is limited, often requiring careful exposure choices or post-processing compromise.

So, if image quality is paramount (say, client work, gallery prints, or serious landscape shoots), the Sony’s full-frame sensor is an unbeatable advantage. But if you’re after quick grabs with versatile zoom and easy sharing, the Canon serves well.

Navigating the Interface: Screens, Viewfinders, and User Experience

Another critical consideration for hands-on photographers is how well the camera interfaces accommodate your shooting style.

The Canon SX720 HS has a 3-inch fixed LCD screen with 922k-dot resolution, which is bright and reasonably sharp for framing shots or menu navigation. However, the lack of a touchscreen makes quick focus shifts or menu changes less intuitive, and the absence of an electronic viewfinder (EVF) means composing exclusively via LCD in all lighting conditions - a challenge under bright sunlight, where glare kills visibility.

The Sony A7R II’s 3-inch tilting LCD boasts a higher 1.23 million-dot resolution, which makes reviewing images a delight. It also sports a high-res 2.36M-dot OLED electronic viewfinder that covers 100% of the frame with 0.78x magnification. For me, this EVF is a game changer: it offers eye-level shooting, precise focus checking, and reduced eye fatigue during long sessions or harsh daylight.

While the Sony lacks touchscreen functionality (a bit surprising for a modern camera at its price point), its button and dial ergonomics compensate, providing swift access to settings without fumbling. The Canon’s simplified controls suit beginners but feel limiting for advanced users.

Lens Options and Zoom Capabilities: Fixed Versus Interchangeable

A considerable gulf exists between these models’ optical systems.

The Canon SX720 HS is equipped with a fixed 24-960mm equivalent lens - an impressive 40x optical zoom that covers ultra-wide to super-telephoto ranges. This makes the SX720 an outstanding pocket telescope for wildlife snapshots, distant monuments, or casual travel photography without the burden of multiple lenses.

However, the lens’ maximum aperture varies from f/3.3 at the wide end to a rather dim f/6.9 at full telephoto. This brightness limitation constrains low-light capability and depth-of-field control. Additionally, fixed lenses limit creative flexibility.

In contrast, the Sony A7R II leverages the immensely versatile Sony E-mount lens ecosystem. With over 120 native lenses catering to every genre - fast primes for portraits, macro lenses for intricate close-ups, ultrawide landscapes, and super telephoto zooms for action and wildlife - the A7R II offers unmatched creative expansion. Lens changeability is key for professionals who demand optical excellence for each scenario.

The 5-axis in-body image stabilization on the Sony further enhances telephoto and macro performance, allowing sharper images at slower shutter speeds - something the Canon SX720 lacks.

Autofocus: Staying Sharp When It Counts

In my hands-on tests, autofocus performance often dictates user satisfaction.

The Canon SX720 HS employs a contrast-detection AF system with 9 focus points (including face detection), and provides tracking AF and continuous focus modes. While it does a decent job locking focus in good light, speed and accuracy diminish under low light or fast motion. The lack of phase-detection AF limits predictive tracking, which is noticeable when attempting wildlife or sports shots at long zoom.

Sony’s A7R II sports a hybrid autofocus combining 399 phase-detection points and 25 contrast-detection points, widely regarded as one of the best systems available at its launch. It offers swift, accurate, continuous tracking - even for erratic subjects like birds in flight or fast athletes. Face and eye-detection AF work reliably, a boon for portraiture.

This autofocus superiority generally translates into a much higher keeper rate, less frustration behind the lens, and more creative freedom to capture fleeting moments.

Shooting Performance: Burst Rate and Shutter Speeds

Burst rate and shutter speed windows impact sports, wildlife, and action photographers significantly.

The Canon SX720 offers 5.9 fps continuous shooting at its full resolution, with a shutter speed range of 15s to 1/3200s. For superzoom compacts, that’s reasonable but not exceptional. The max shutter speed limitation can curtail shooting in bright light wide open.

Sony’s A7R II clocks 5 fps burst rate - slightly slower but with a far higher-resolution sensor, which is impressive. Shutter speeds span from 30s up to 1/8000s, covering a broad range of creative shutter control, including freezing fast action and long exposures.

In real-world use, the A7R II’s burst buffer and AF tracking confer a competitive edge for wildlife and sports shooters demanding precision timing.
