Nikon D800 vs Sony A77 II: An Expert’s Side-by-Side Exploration of Two Advanced DSLRs

Choosing an advanced DSLR that matches your evolving photography style and workflow is never purely about megapixels or shutter speeds. It’s about the confluence of sensor technology, autofocus finesse, handling comfort, and how all these tools marry your creative necessities on the field. Today, I’m diving deep into two noteworthy “mid-size SLR” cameras from a slightly past era - the Nikon D800 (2012) and the Sony A77 II (2014). Having personally run thousands of test shots and scenarios on both, I’ll walk you through a comprehensive head-to-head comparison that covers every vital photography genre, practical performance measures, and usability aspects that really matter.

Let’s get into the grit and grace of these cameras.

First Impressions: Size, Feel, and Build Quality

When grabbing a camera, the first tactile connection profoundly impacts long shoots. While specs tell one story, hands-on experience often reveals how intuitive a device truly is.

Here, the Nikon D800 comes in as a substantial, sturdy beast - bigger and heavier at 900 grams with dimensions of 146mm x 123mm x 82mm. It’s not just weight; the D800’s magnesium alloy body and weather sealing bring a durable, pro-grade feel. For landscape photographers often battling rough environments or sports shooters in variable conditions, this solidity signals reliability, especially with its environmental sealing to fend off dust and moisture ingress.

The Sony A77 II, by contrast, is lighter at 647 grams and marginally smaller in footprint (143mm x 104mm x 81mm). It’s less imposing and more nimble, which will appeal to street shooters and travellers valuing discretion and ease over sheer robustness. Still, it doesn't skimp on body strength or sealing, offering environmental protection that should suffice for most fieldwork barring extreme conditions.

In practical terms, prolonged handheld use reveals the Nikon’s heft aids steadiness, while Sony’s lighter profile reduces fatigue, especially when paired with smaller lenses. The D800’s grip is beefier, accommodating larger hands with greater comfort and control.

The ergonomics discussion continues as we look at top controls:

The Nikon’s control layout is classic: dedicated dials for ISO, exposure compensation, and a top LCD info panel make tactile adjustments swift without diving into menus. Sony adopts a more modern, streamlined organization, with fewer physical dials but a generously functional top screen and customizable buttons. For photographers used to tactile immediacy (think wedding or sports shooters needing rapid exposure changes), Nikon pulls ahead. Sony’s setup is not clunky, but more menu-dependent and arguably less intuitive in fast-paced environments.

Sensor Technology and Image Quality: Debating the Full Frame vs APS-C Divide

The heart of any camera is its sensor. Here is where the two differ most fundamentally and profoundly affect subsequent use.

The Nikon D800’s 35.9 x 24 mm full-frame CMOS sensor packs an impressive 36.3 megapixels - a resolution leap even now respected for delivering ultra-high detail and tonality. That larger sensor area (approximately 862 mm²) directly translates to better light-gathering ability per pixel, improved dynamic range, and cleaner high ISO performance. For studio portraiture, landscapes, or commercial work demanding fine detail retention and extensive cropping latitude, the D800 remains a tough reference point.

By contrast, the Sony A77 II sports a smaller APS-C sensor measuring 23.5 x 15.6 mm with 24 megapixels. While smaller, Sony’s APS-C is generously resolving and competent in most lighting, benefiting from the Bionz X processor and back-illuminated sensor design for enhanced noise control. However, low light ISO performance and dynamic range cannot quite match Nikon’s full-frame prowess - notable especially beyond ISO 1600.

Real-world testing in natural and controlled light confirms these observations:

• Dynamic Range: Nikon’s sensor extends around 14.4 EV stops (measured by DXOMark), offering greater latitude for preserving highlights and shadows. Sony’s A77 II lands slightly lower at 13.4 EV stops, still respectable but more prone to clipping in harsh light conditions.

• Color Depth: The D800 records 25.3 bits vs. 24.4 bits for Sony, a subtle but real advantage in color gradation sophistication, critical for skin tones and subtle ambient hues.

• High ISO: Nikon’s native max ISO of 6400 with expandable to 25600 stands comfortably against Sony’s higher max ISO 25600, but with Nikon delivering cleaner images at elevated sensitivities thanks to sensor size.

In essence, the D800 is your best bet for applications where ultimate image quality and flexibility in post-processing reign supreme.

Handling the Screen and Viewfinder: Where Optical and Electronic Clash

Display and viewfinder technology define how a photographer interfaces with the scene before the shutter clicks.

The Nikon D800 uses a fixed 3.2” TFT LCD with 921,000 dots and a wide 170-degree viewing angle. This screen offers sharp, natural rendering of images and menu readouts but lacks touch or articulation features. This can be limiting when shooting off-angle or in cramped spaces where tilting might ease composition.

The Sony A77 II compensates with a 3” fully articulated LCD boasting a higher 1,229,000-dot count. This flexibility suits videographers and photographers working from low, high, or awkward angles. Plus, Sony’s screen is “selfie-friendly,” a nod to its appeal for casual or vlog-style usage, albeit without touchscreen responsiveness.

The viewfinder debate is also quite polarizing:

• D800: Optical pentaprism viewfinder with 0.7x magnification and 100% coverage, offering an unmediated, natural scene view appreciated by traditionalists. Optical finders excel with zero lag, pristine clarity in bright light, and zero color artifacts.

• A77 II: Electronic viewfinder (EVF) with a high resolution of 2,359k dots and 100% coverage. The EVF provides real-time exposure preview, focus peaking, and histogram overlays, invaluable during tricky exposures and manual focus. However, some users report slight lag or rainbow artifacts in fast-moving scenes, typical of EVFs.

For purists and studio shooters, Nikon’s optical finder keeps the edge. For those embracing digital versatility and real-time information, Sony’s EVF offers undeniable smart advantages.

Autofocus Systems: Precision, Speed, and Tracking

Autofocus (AF) can make or break shooting fast-moving subjects - so this is a crucial battleground.

The Nikon D800 masters autofocus with 51 points (15 cross-type) all-phase detection sensors spread generously across the frame, paired with face detection and multi-area AF modes. This system proved stellar in accuracy and consistency during my wildlife testing, locking onto erratic bird wings with remarkable steadiness. However, the burst rate tops out at 4 fps, making it less suited for high-action sports.

Sony stepped up technologically for the A77 II, integrating a 79-point AF system (15 cross-type) with an advanced hybrid AF combining phase detection and contrast detection. The continuous shooting rate hits 12 fps - three times Nikon’s pace - yet with continuous AF tracking active, a standout on paper and in action. This made the A77 II a winner for sports and wildlife enthusiasts needing speed and flexible subject tracking.

However, in low-light focus tests under tungsten illumination, Nikon’s superior sensor sensitivity helped it retain focus accuracy slightly better. Sony’s hybrid system could hunt intermittently in dimmest conditions.

In terms of animal eye autofocus - neither model supports modern implementations, a feature now popular and useful but understandably absent given their age.

Image Stabilization and Shutter Mechanism Impact

One must note the inclusive image stabilization difference:

• Nikon D800 requires stabilized lenses for shake reduction; the camera mount itself lacks in-body stabilization (IBIS).

• Sony A77 II features sensor-shift stabilization, compensating for camera shake regardless of attached lens. This is a boon for handheld macro and low-light shooting, noticeably smoothing results without tripod reliance.

Regarding shutter durability and noise:

• Nikon’s mechanical shutter offers a lifespan around 200,000 cycles, with a quiet but definitive click.

• Sony’s SLT design uses a fixed translucent mirror, eliminating mirror slap and reducing shutter lag and vibration - great for quiet environments, though some photographers may find the audible shutter sound less refined.

Storage, Connectivity, and Battery Life for Long Hauls

Both cameras offer dual slot opportunities but differ in implementation.

Nikon’s D800 supports both CompactFlash Type I and SD cards simultaneously - a photographer-friendly feature allowing overflow or backup, increasing workflow flexibility.

Sony A77 II opts for a single card slot (compatible with SD and Sony Memory Stick formats), which may be limiting for professionals desiring instant backups or extended storage capacity.

Battery life tells a similar story:

• Nikon D800’s EN-EL15 offers approximately 900 shots per charge, impressive for long shoots or remote use.

• Sony’s NP-FM500H falls to about 480 shots, closer to the typical APS-C DSLR range, meaning you might need to carry backups during intensive sessions.

Connectivity-wise, Sony edges out slightly with built-in WiFi and NFC for wireless sharing and remote control - practical features for fast online uploads or tethered shooting without cumbersome cables. Nikon’s D800 does not offer wireless connectivity natively but does support optional external GPS modules enhancing geotagging capabilities.

Lens Ecosystems: Critical for Growth and Flexibility

Nikon’s F-mount lenses number over 309, encompassing everything from pro-grade Nikkor primes and zooms to highly specialized macro and tilt-shift optics. The breadth and quality make it a versatile system - from high-speed 85mm f/1.4 portraits to 600mm super-telephotos for wildlife.

Sony’s Minolta Alpha mount lens count stands roughly at 143, fewer but supplemented by Sony’s recent E-mount mirrorless lenses via adapters, albeit with variable AF performance. Admittedly, Sony’s native lens lineup for the A77 II era was strong on quality primes but limited on ultra-specialized optics or fast zooms - possibly constraining professionals heavily reliant on lens variety.
