Nikon Z7 II vs Sony A7R II: A Deep Dive into Two Pro Mirrorless Giants

When I first picked up the Nikon Z7 II alongside the Sony A7R II for hands-on testing, I knew I was holding two serious contenders in the full-frame mirrorless arena. These cameras target enthusiasts and professionals who crave stellar image quality, robust build, and modern versatility. Although their debut dates are five years apart and they hail from different technology generations, comparing these models still provides valuable insights into how camera advancements have shaped user experience and performance.

In this thorough comparison, I’ll take you through everything from sensor tech and autofocus to ergonomics, lenses, and everyday usability. Drawing on years of field experience shooting portraits to landscapes, wildlife to street scenes - and countless lab tests with sensors and autofocus - I aim to arm you with an honest, practical guide tailored to your photographic journey.

Let’s dive in.

Size and Handling: Ergonomics That Make or Break Your Shoot

Handling a camera comfortably is foundational, especially when long shoots and changing conditions demand fast operation without fuss. The Nikon Z7 II and Sony A7R II both adopt an SLR-style mirrorless body, but they differ notably in size, weight, and design approach.

The Nikon Z7 II tips the scales at 705g (body only) and measures roughly 134 x 101 x 70mm. It feels substantial yet balanced in my hand, thanks partly to the deeper grip and slightly larger frame. The build quality exudes confidence - weather sealing is comprehensive, suitable for rigorous professional use in diverse environments.

The Sony A7R II, meanwhile, is more compact and lighter at 625g, measuring about 127 x 96 x 60mm. This makes it noticeably more pocketable and discreet, a boon for street and travel photographers who prioritize nimble setups. However, its grip can feel less secure if you have larger hands or use heavy telephoto lenses.

For me, the Nikon’s size enables more confident handling with bigger lenses and longer sessions, while the Sony appeals to shooters preferring stealth and portability.

Top Controls and Interface: Where Intuition Meets Speed

Responsive control layouts can elevate your creative workflow or frustrate when menus and buttons aren’t thoughtfully placed. Both cameras opt for tilting rear screens and robust EVFs, but their control philosophies diverge significantly.

The Nikon Z7 II’s top plate has a dedicated ISO dial, exposure compensation wheel, and an additional customizable button. This thoughtful arrangement allows me to adjust settings quickly without taking my eye off the viewfinder - critical when chasing fast wildlife or spontaneous street moments. The presence of dual UHS-II and CFexpress/XQD slots also reflects Nikon’s emphasis on reliability and professional readiness.

Sony’s A7R II opts for a minimalist approach, with fewer dedicated dials on top but a well-designed back wheel system. However, the absence of a touch interface means more menu diving for certain functions, which slowed me down in dynamic scenarios. It does have an illuminated button system on neither body, which is a minor letdown for low-light shooting.

In summary: Nikon’s controls feel more ergonomic and intuitive for on-the-fly adjustments, while the Sony excels for photographers comfortable navigating menus and micromanaging settings.

Sensor and Image Quality: The Heart of the Matter

Evaluating sensor tech is what I find most exciting. The Z7 II boasts a 45.7MP back-illuminated (BSI) CMOS sensor, while the A7R II houses a 42.4MP BSI CMOS sensor - both full frame but from slightly different eras.

The Nikon’s sensor size is essentially identical in physical dimensions (35.9mm x 23.9mm), providing a native ISO range of 64-25600 expandable to 32-102400. The Z7 II captures stunningly detailed RAW files with excellent dynamic range, allowing me to recover shadows and highlights impressively on landscape shots taken at dawn or dusk.

Sony’s A7R II, though older, scores highly on DxOmark (overall 98), with a color depth of 26 bits and dynamic range of 13.9 stops - numbers that rival many current models. However, the Sony’s minimum native ISO starts at 100, slightly limiting low-ISO performance versus Nikon’s cleaner 64 base ISO.

In practical shooting, the Nikon’s newer sensor translates to slightly better noise control at high ISO, cleaner color rendition - especially for skin tones - and a broader tonal latitude on challenging scenes. Landscapes benefited noticeably in my real-world tests.

Both cameras lack anti-aliasing filters, so fine details and textures appear crisp, but Nikon’s sensor improvements underscore a step forward in low light and highlight management.

Autofocus: Sharpness where It Counts

Autofocus systems can make or break your experience, especially for fast-moving subjects in wildlife and sports photography.

The Nikon Z7 II comes with an expansive 493-point phase-detection AF system that covers nearly 90% of the frame. It supports face, eye, and even animal eye detection focusing - features I found remarkably reliable during bird-in-flight and portrait sessions. Continuous AF tracking and responsiveness have been polished over its predecessor’s already competent system.

Sony’s A7R II employs a 399-point hybrid AF system, which in 2015 was groundbreaking, and still delivers solid performance. However, it lacks dedicated animal eye AF and touch-focusing options, which became immediately obvious when testing for fast wildlife sequences.

Sony’s autofocus works well under steady conditions but occasionally hunts in lower light or with erratic subjects, making Nikon’s system feel more versatile and modern. For street photography, both cameras focus quickly on faces, but Nikon’s eye detection gave it a slight edge in precision.

Shutter and Continuous Shooting: Capturing the Moment

If you frequently shoot sports, wildlife, or fleeting street moments, frame rate and shutter reliability weigh heavily in your choice.

The Nikon Z7 II features a shutter speed range of 30s to 1/8000s, with a silent electronic shutter option. It shoots at up to 10 fps with continuous AF - fast enough for most action scenarios.

By contrast, Sony’s A7R II maxes out at 5 fps continuous shooting speed. Its shutter speed range is comparable but lacks the silent electronic shutter option, which can be an issue in noise-sensitive environments like weddings or wildlife hideouts.

Testing both in a sports arena, Nikon allowed me to capture faster bursts with consistent AF tracking, resulting in a higher keeper ratio. The Sony was more deliberate, better suited for static or slower-paced subjects.

LCD and Electronic Viewfinder: Your Eye to the World

Critical for composition and previewing images, the rear monitor and EVF quality define user comfort and shooting confidence.

Nikon equips the Z7 II with a 3.2-inch tilting touchscreen at 2.1 million dots, offering sharp, color-accurate display and very responsive touch AF point selection. This came in handy rapidly shifting focal points during candid portrait sessions.

Sony’s A7R II has a 3-inch tilting screen at 1.23 million dots and lacks touchscreen capabilities. It’s bright and adequate but less intuitive for quick AF adjustments. The electronic viewfinder, in contrast, is less impressive at 2.36 million dots versus Nikon’s 3.69 million dots EVF with 0.8x magnification - a tangible difference when shooting in challenging light.

The Nikon’s displays feel like a step ahead, enhancing live preview precision and menu navigation fluidity.

Lens Ecosystem: Which System Grows With You?

Lens choice and availability are vital for investment longevity and creative versatility.

Sony’s E-mount system is mature and expansive, boasting over 120 native lenses from Sony plus a broad third-party offering from Sigma, Tamron, and Zeiss. This array ranges from ultra-wide primes to super-telephoto zooms, optimized for video and stills alike.

Nikon’s Z mount, in contrast, is younger with about 15 native lenses at the Z7 II’s launch. That number is growing steadily, balancing high-quality primes and versatile zooms. You can also adapt Nikon’s huge F-mount DSLR lens library nearly seamlessly with the FTZ adapter, retaining autofocus and in many cases image stabilization.

For photographers wanting broad glass options now, Sony’s ecosystem leads. But if you have Nikon legacy lenses or prefer the newest optical engineering from Nikon’s Z lineup, the Z7 II is compelling.

Battery Life and Storage: Powering Through the Day

Reliable power and data handling can’t be overlooked, especially on demanding assignments.

The Nikon Z7 II houses a 420-shot battery life per CIPA ratings - an improvement over many mirrorless peers. Additionally, it features dual storage slots supporting CFexpress/XQD and UHS-II SD cards simultaneously. I found this dual-slot configuration invaluable for professional workflows requiring instant backup or splitting RAW and JPEG.

Sony’s A7R II accommodates a single NP-FW50 battery rated for around 290 shots, noticeably less than the Nikon. It also offers one card slot supporting SD and Memory Stick Duo cards.

In real-world use, Nikon’s longer battery endurance reduced mid-shoot swaps significantly, and having two card slots can be a game-changer for risk-averse pros.

Video Capabilities: Beyond Still Photography

For hybrid shooters, video specs and processing matter.

The Nikon Z7 II supports 4K UHD at 60fps (via full sensor readout, no crop) allowing high-quality slow-motion or cinematic capture. It can output 10-bit through HDMI and records in H.264 MOV format with linear PCM audio. Both mic and headphone jacks allow professional monitoring and capture.

Sony’s A7R II offers 4K up to 30fps using full pixel readout and no pixel binning - impressive for a 2015 camera - compressed internally with XAVC S codec. Although it has mic and headphone ports, the older USB 2.0 connection and lack of 10-bit support limit professional video uses today.

If video is secondary, both are capable; for extended or advanced filming, Nikon’s Z7 II has noticeable advantages.
