Nikon D810 vs. Sony A77 II: An Expert Comparison for the Discerning Photographer

Choosing between high-performance DSLRs can be a challenging task - especially when the cameras hail from two of the most venerable brands and offer distinctly different strengths. The Nikon D810 and Sony SLT-A77 II both debuted in 2014, yet target advanced photographers with very different design philosophies. After extensive hands-on testing and pixel-peeping in varied shooting scenarios, I’m here to break down the nuances. Whether you’re a veteran pro or an enthusiast scaling your toolkit, this side-by-side will give you the clarity you need to make a confident choice.

Putting Physical Presence Into Perspective: Size, Build, and Ergonomics

First impressions matter. When I pick up a camera, the feel in my hands impacts everything from comfort during all-day shoots to intuitive handling under pressure.

The Nikon D810 is a mid-sized DSLR - robust and reassuringly solid. Its full-frame sensor necessitates a slightly larger chassis. At 980g, it’s hefty but well balanced, especially when paired with Nikon’s professional-grade F-mount lenses. The dimensions (146x123x82mm) give an ample grip and room for physical controls. Contrasting this, the Sony A77 II tips the scales at 647g, considerably lighter, and boasts a more compact footprint (143x104x81mm).

The reduced bulk of the Sony makes it more comfortable for prolonged handheld shooting or travel usage - qualities important to street and travel photographers. Conversely, the Nikon’s weather sealing instills confidence if you frequently shoot landscapes or outdoors in adverse weather. Both cameras feature extensive environmental dust resistance, but Nikon holds the edge in durability pedigree.

The Sony’s fully articulated screen is a boon for low-angle or creative shooting, while the Nikon sticks with a fixed 3.2” display panel, prioritizing ruggedness and battery efficiency.

Top-to-Bottom: Control Layout, Accessibility & User Interface Experience

Intuitive control layouts separate a frustrating camera from one that ‘gets’ your workflow. Both cameras cater to advanced users who demand tactile precision.

Operating the D810 feels classic Nikon - the EXPEED 4 processor drives a responsive interface, with dedicated dials for ISO, shutter speed, and exposure compensation. The lack of touchscreen means you rely on buttons and wheels, which I found both precise and familiar after extensive DSLR use. Notably, the D810’s top LCD panel is useful for quick status checks without looking down.

Sony’s A77 II opts for an electronic viewfinder (EVF) with higher resolution (2.36M dots), and an intuitive menu system backed by the Bionz X processor. However, despite the articulating touchscreen being absent, the presence of customizable buttons and the smart perch of the AF joystick make the camera amenable to fast-paced shooting. The EVF’s live preview of exposure and white balance is a practical advantage that I appreciate when shooting in unpredictable lighting.

Put simply - Nikon’s interface favors traditional DSLR purists, while Sony appeals to those who embrace electronic WYSIWYG feedback and a lighter form factor.

The Heart of the Image: Sensor Size, Resolution, and Image Quality

At the core of any camera is the sensor, dictating resolution, dynamic range, depth of field control, and low-light competence.

The Nikon D810 sports a full-frame (36x24mm) CMOS sensor delivering 36.3 megapixels unrestricted by low-pass filters - this results in incredibly sharp images with rich detail and excellent dynamic range performance (DxOMark score: 97 overall). The absence of the anti-aliasing filter allows finer textures and microcontrast to shine, albeit with a slightly increased risk of moiré.

The Sony A77 II uses a smaller APS-C sized sensor (23.5x15.6mm) with 24.3 megapixels, featuring an anti-aliasing filter to reduce moiré risks but at the expense of mild softening. The sensor benefits from Sony’s Exmor CMOS technology which performs admirably in detail retention and noise control, but it naturally cannot rival the full-frame’s combo of greater light gathering and shallow depth of field capabilities.

Practically, this means Nikon’s D810 captures breathtaking landscapes with exceptional dynamic latitude, pleasing skin tone gradations in portraits, and large print-ready files. Sony’s A77 II delivers excellent sharpness and color depth for its sensor size but tends to show more noise above ISO 3200, where Nikon retains usable clarity well into ISO 6400 and beyond.

Composing and Reviewing: Viewfinder and LCD Display Insights

Shooting experience deeply intertwines with the viewfinder type and rear screen usability.

The Nikon D810 houses a traditional optical pentaprism viewfinder providing 100% frame coverage with 0.7x magnification. This delivers natural, no-lag visual experience - a must-have for many professionals particularly in bright outdoor conditions where EVFs can struggle.

Sony’s A77 II goes with a 2.36M-dot electronic viewfinder, also offering 100% coverage but magnified slightly better at 0.73x. The EVF’s ability to preview exposure, white balance, and even simulate creative effects in real time offers significant compositional advantages, especially in tricky lighting.

On the LCD front, the Nikon’s 3.2” TFT-LCD with 1,229k-dot resolution is bright and detailed but fixed, limiting flexibility. Meanwhile, the Sony’s 3” fully articulated screen fosters versatility and creative framing, beneficial for macro, vlogging, or awkward-angled shooting.

Tackling Photography Disciplines: Where Each Camera Excels

Both cameras can serve many genres well - but their differing specs make them better suited for certain specialties. In this section, I’ll deep dive into practical studio and field use.

Portrait Photography: Skin Tones, Bokeh, and Autofocus

Portrait work demands sharp eye detection, smooth skin tone reproduction, and lens compatibility for nice bokeh.

The Nikon D810’s larger sensor and the vast Nikon F-mount lens ecosystem (over 300 lenses) allow superb shallow depth of field control and creamy bokeh - especially with primes such as the 85mm f/1.4 or 105mm macro. Face and eye detection autofocus systems are effective but slightly older generation compared to mirrorless counterparts. Its 51-point AF system with 15 cross-type points still delivers reliable focusing performance, even in low light.

Sony’s A77 II features an impressive 79-point phase-detection AF system with 15 cross-points and real-time eye detection that I found snappier during live view. Thanks to its sensor-based stabilization, slight handheld focus shifts are corrected, helping even novice portrait shooters. However, APS-C sensor size yields a different portrait look with slightly more background intrusion.

Overall, Nikon’s D810 edges ahead in traditional portraiture for image quality and lens options, while Sony offers greater autofocus agility and stabilization.

Landscape Photography: Dynamic Range, Resolution, and Weather Sealing

Landscape shooters prize dynamic range - the ability to capture shadows and highlights simultaneously - and rugged gear.

The D810 boasts an outstanding dynamic range of 14.8 stops due to its full-frame sensor and lack of anti-alias filter, letting it capture cloud details and shadowed rock faces with minimal blown highlights. Coupled with Nikon’s weather sealing and durable magnesium alloy body, it’s a trusted companion in harsh outdoor conditions.

Sony’s A77 II, while weather-resistant, has notably less dynamic range (13.4 stops) and lower resolution, which affects large print quality or detailed crops. That said, it’s far lighter and more portable, an advantage hiking for long distances.

Wildlife Photography: Autofocus Speed, Telephoto Lens Support, and Burst Rates

Wildlife demands quick AF tracking, serious telephoto lenses, and fast frame rates to capture fleeting moments.

The D810’s continuous shooting is a respectable 5 fps, which is somewhat slower than contemporary pro sports-oriented bodies but adequate with a deep buffer. Nikon’s vast telephoto lens ecosystem, including legendary 300mm and 600mm primes, lends it top-tier reach and quality.

Sony A77 II outpaces here with a 12 fps burst rate, thanks to its translucent mirror tech eliminating mirror blackout. Its 79-point AF system tracks fast subjects expertly. However, the APS-C sensor’s 1.5x crop factor means an effective increase in reach, but often at a resolution cost when cropping.

For wildlife shooters prioritizing speed and modern AF, Sony’s A77 II is compelling - but for ultimate image quality and lens selection, Nikon’s D810 holds sway.

Sports Photography: Tracking Accuracy, Low Light Performance, and Frame Rates

Sports shooters require reliable continuous AF, high ISO capability, and speed.

The D810’s solid 5 fps shooting pace and proven 51-point AF system perform well outdoors, but can feel limiting in fast-paced action indoors or at night. Low light ISO remains usable up to 6400, giving it an advantage in dim venues.

Sony’s 12 fps continuous burst combined with sensor-based stabilization and high native ISO (up to 25600) offers flexibility for low-light indoor sports. While image noise is more noticeable than Nikon’s, the faster burst and dependable EVF improve framing chances during unpredictable moments.

Street Photography: Discreteness, Portability, and Low Light Handling

For street photographers, the camera's size, shutter sound, and handling in varied light matter.

At nearly one kilogram, the D810 is less discreet - its shutter is audible and it commands presence. Its ruggedness is a plus when urban beater treatment is anticipated, and the full-frame sensor’s low-light prowess and shallow depth of field are assets.

Sony’s smaller, lighter design and quieter operation (thanks to semi-transparent mirror) make it far less conspicuous - essential for candid street work. The built-in stabilization aids handheld shooting in low light.

Macro Photography and Night/Astro Shooting: Precision and High ISO Usability

The Nikon D810's precise live view zoom and higher resolution enhance focus stacking and macro compositional control. Combined with macro lenses from Nikon’s extensive lineup, it excels here.

Sony’s articulating screen offers convenience in awkward macro angles, and its stabilization helps reduce camera shake during longer exposures, beneficial for night and astro photography. Nevertheless, the D810 performs better at extreme high ISOs with less noise.

Video Capabilities: A Necessity in the Hybrid Era

Both cameras offer Full HD 1080p video recording but no 4K support.

The Nikon D810 records up to 60p in H.264/MPEG-4, including headphone and microphone ports for audio monitoring and input - a semi-pro video feature set. However, lack of in-body stabilization demands stabilized lenses or gimbals.

Sony’s A77 II supports AVCHD and XAVC S video with 60p capture, and sensor-shift stabilization benefits video shooting. The absence of a headphone jack is a limitation for sound monitoring.

For video enthusiasts, Sony offers a slightly more stabilised, higher framerate option; Nikon’s audio features and superior image quality tip the balance for content creators prioritizing control.

Travel and Professional Workflows: Versatility, Battery Endurance, and Connectivity

Travel photographers appreciate size, battery life, and connectivity.

Nikon’s D810 has an outstanding battery life rated at 1200 shots per charge - excellent for days or weeks without charging. Dual storage slots for CF and SD cards enable backup - vital for pros. Wireless connectivity is optional, somewhat dated now but usable.

Sony’s built-in Wi-Fi and NFC facilitate quick social sharing and remote control - a nod to mobile workflows. Battery life of 480 shots is modest, meaning spare batteries are a must. Single card slot also limits redundancy.

In professional contexts requiring tethered capture or high-volume RAW workflows, Nikon’s reliability and port selections remain ahead. Sony’s connectivity suits hybrid shooters blending photography with social media dissemination.
