Both are heavyweight contenders in Nikon’s full-frame DSLR lineup, aimed at serious enthusiasts and professionals. While the D800 revolutionized full-frame imaging with its staggering 36MP sensor and rich feature set back in 2012, the D780 arrived in 2020 with a modernized personality that embraces hybrid shooting - DSLR form with mirrorless guts.

Having logged hundreds of hours shooting with both cameras across genres - from intimate portraits on golden-hour streets to blistering bird-in-flight sequences in wild terrain - I want to take you through an in-depth, no-nonsense comparison. I’ll dissect the specs, share real-world findings, and offer clear recommendations based on my hands-on experience.

Whether you are upgrading from an older model or weighing these models against other cameras, this detailed exploration should settle whether the venerable D800 or the versatile D780 deserves your hard-earned investment.

First Impressions: Size, Build, and Ergonomics Up Close

Both cameras share Nikon’s characteristic robust mid-sized SLR body, designed to withstand demanding fieldwork, but subtle differences define their handling personalities.

The Nikon D780 (left) is slightly more compact and lighter than the older D800 (right), impacting portability and grip comfort.

The D780 weighs in at approximately 840g with dimensions of 144x116x76mm, slightly lighter and more compact than the D800’s heftier 900g and 146x123x82mm footprint. While neither is pocketable, the weight difference is noticeable during long handheld sessions - the D780's subtly refined grip contours feel sleeker and less bulky in my hands.

The D780 feels purpose-built for a broad hybrid usage pattern, offering a tilting touchscreen that modernizes composition and image review, whereas the D800 sticks with a fixed screen with much lower resolution. Both feature magnesium alloy chassis with environmental sealing, confident companions in rain or dusty landscapes, although neither is fully waterproof.

The D780 refines the control layout with illuminated buttons and a touch-enabled LCD, giving it an ergonomic edge over the D800’s more dated interface.

Controls on the D780 are more intuitive: touch-enabled menus and customizable buttons streamline workflow, especially in live view mode where touch-focusing is invaluable. The D800 retains classic, reliable physical controls but feels slightly less fluid for video or fast-paced live shooting.

Practical Tip: If you spend much time in live view or video mode, the D780’s intuitive touchscreen will noticeably speed up your workflow.

Sensor and Image Quality: Megapixels, Dynamic Range, and ISO Performance

Arguably the heart of any camera, image quality depends heavily on sensor technology. This is where the D780’s newer sensor shines - pun intended.

Both cameras employ full-frame sensors of similar physical size, but the D780 features a newer backside-illuminated CMOS sensor that boosts sensitivity and noise control.

The D800 has a 36.3-megapixel CMOS sensor that made waves upon release for its phenomenal resolution, delivering ultra-detailed 7360x4912 pixel images perfect for large prints and extensive crops. However, this older sensor uses a front-illuminated design and benefits differently from post-processing.

The D780 sports a newer 24.5-megapixel backside-illuminated (BSI) CMOS sensor, paired with Nikon’s fast EXPEED 6 processor. Although it trades some megapixels, this design significantly enhances high ISO noise performance and dynamic range - a boon when shooting in challenging light.

In practice, I noticed that the D780 offered cleaner images at ISOs over 6400, making it more versatile for event photography or shadowed scenes. The D800’s strength lies in daylight and studio photography where fine detail and resolution trump sensitivity.

The D800's dynamic range performance is excellent too, with over 14 stops allowing shadow recovery, but the D780 catches up with its sensor optimization, especially in JPEGs and RAW files converted in modern software.

Technical Insight: The BSI sensor architecture in the D780 relocates wiring behind the photodiodes, improving quantum efficiency. This translates into better light gathering and improved signal-to-noise ratio at higher ISOs - a key for low-light and night photography.

Autofocus Systems: Precision Meets Speed

A photographer’s real-world experience often hinges on autofocus reliability and speed. Here, technological leaps between the 2012 D800 and the 2020 D780 become evident.

Both cameras use a 51-point autofocus system with fifteen cross-type sensors for precise tracking, but the D780 benefits from several crucial upgrades.

• The D780 combines traditional phase-detection AF for viewfinder shooting with hybrid on-sensor phase-detect and contrast-detect AF during live view and video.
• The D800 relies solely on phase-detection AF in the viewfinder, with contrast detection during live view, which is notably slower.

During wildlife and sports sessions, I found the D780’s autofocus superior for continuous tracking - the 7fps burst rate combined with eye-detection AF (which the D800 lacks) prevents missed shots of fleeting moments. In contrast, the D800 manages a slower 4fps and lacks sophisticated subject tracking, often requiring more deliberate focus lock before capturing critical action.

The D780’s tilting touchscreen facilitates intuitive AF point selection and focus confirmation, enhancing autofocus usability compared to the fixed lower-res screen on the D800.

That said, both cameras depend on quality lenses to maximize AF speed and accuracy. With Nikon F-mount compatibility and a broad ecosystem of over 300 lenses, users of either camera enjoy extensive glass options.

Portraits and Bokeh: Rendering Skin Tones and Eye-Detection

In portrait photography, subtlety counts: not just resolution but how skin tones, bokeh smoothness, and focus precision come together to create compelling images.

The D800’s higher pixel count means more detail in skin textures and fabrics, ideal for studio setups or formal portraiture. However, this also reveals minor skin imperfections more aggressively, which might not suit every style.

The D780’s 24MP sensor strikes a balance by smoothing out textures slightly while maintaining ample detail. Its expansive ISO range and superior autofocus with eye-detection, introduced in this generation, helped me nail sharp focus on eyes even at wide apertures.

Bokeh quality relates heavily to the lens but also sensor performance. Both cameras employ anti-aliasing filters, yet the D780 introduced subtle improvements in rendering tonal transitions smoother - beneficial with fast primes like the 85mm f/1.8 I frequently use.

Ultimately, for portraitists seeking ultra-high resolution, the D800 is still formidable, but the D780 offers modern touchpoints like eye AF and better low-light focus, critical for events and candid portraits.

Landscape Photography and Resolution Trade-Off

Landscape shooters will feel the D800's 36MP resolution offering netting large prints or detailed panoramas is the compelling reason to consider it. The finer pixel pitch captures intricate leaf veins, craggy mountain textures, and subtle tonal gradations exceptionally well.

That said, the D780’s sensor, with 25MP, still delivers razor-sharp images with excellent dynamic range - enough for most landscape work without excessive file sizes. It also offers an edge handling harsh lighting or early morning lows thanks to enhanced ISO range and better highlight retention.

Built to weather the elements, both models offer weather sealing to keep dust and moisture at bay, essential during outdoor excursions.

My observation: the D780’s lighter weight and ergonomic enhancements make it preferable for longer treks into wildlands or when juggling hiking gear and camera bags, especially when paired with compact Nikkor lenses.

Wildlife and Sports Focus: Speed and Tracking Under Pressure

One of the biggest differences surfaces shooting fast-moving subjects.

The D780’s autofocus system, complemented by 7 frames per second burst shooting, contrast sharply with the D800’s 4fps. This is no trivial difference - every frame counts when shooting action sports, birds in flight, or wildlife.

Tracking accuracy benefits from the D780’s software improvements, including AI-powered phase-detection in live view and the standout eye AF feature that locks on animal eyes too. The D800 relies on older phase-detection modules, which can struggle with erratic movement.

Battery life also plays a role during extended outings: the D780 supports around 2260 shots per charge vs. approximately 900 with the D800, minimizing battery swaps in the field.

Street and Travel Photography: Discreteness, Portability, and Flexibility

For street photographers, the difference in bulk and features can influence spontaneity.

While neither camera is mirrorless-small, the D780’s slightly reduced size and weight make it less intrusive. The silent electronic shutter mode - missing in the specs but present on D780 as per my tests - allows near-silent shooting, ideal for candid moments.

The tilting touchscreen enhances framing from unusual angles, beneficial when shooting from waist level or over crowds.

Travel photographers will also appreciate dual UHS-II SD card slots on the D780 (versus one UHS-I CF and one SD on the D800), allowing faster data transfer and more flexible storage options. Wireless connectivity and Bluetooth make image transfer and remote shooting easier.

Macro and Close-Up Work: Precision and Stabilization

Neither camera has built-in image stabilization, so macro shooting largely depends on handheld stability or stabilized lenses.

The D780’s focus bracketing feature provides an advantage in focus stacking macro photography, a function the D800 lacks natively. This feature proved useful during my tests capturing detailed insect shots, allowing precise control over depth of field extension.

Night and Astro Photography: ISO Performance and Exposure Control

Astro photography benefits heavily from sensor noise performance and exposure flexibility.

Here, the D780’s BSI-CMOS sensor, combined with ISO expandable to 204,800 (native max 51,200), allows cleaner images and longer exposures without severe noise introduction.

The D800’s 36MP sensor offers higher resolution star field captures but struggles more at ISO levels above 6400, producing visibly more noise and requiring denoise processing.

The D780’s live view exposure preview and highlight-weighted metering simplify setting exposure times for stars and night scenes - a workflow improvement I found invaluable during my overnight shoots.

Video Capabilities: 4K and Beyond

Video shooters will find a vast leap between these models.

The D780 supports 4K UHD recording at 30p, a first for Nikon DSLRs in this lineup, whereas the D800 caps at Full HD 1080p 30fps.

The D780 also offers 120fps slow motion in 1080p, clean HDMI output, and the ability to control audio levels via built-in mic and headphone ports - features highly welcomed by hybrid content creators.

While the D800 offers mic and headphone jacks too, its processing limits and lack of 4K confine it primarily to casual video work.

Professional Workflow and Reliability

Both cameras support Nikon’s RAW format and offer comprehensive exposure modes (aperture, shutter priority, manual). Dual card slots on both models enhance workflow resilience.

Build quality and weather sealing earn praise on both, with magnesium alloy bodies designed to endure professional usage. The D780 edges ahead with newer hardware and more efficient battery life for demanding shoots.

Connectivity and Storage: Keeping Up with Modern Demands

The D780 features built-in Wi-Fi and Bluetooth, facilitating seamless image transfer and remote control via Nikon’s SnapBridge app. The D800 lacks wireless connectivity, reflecting its era.

Storage options also differ: D780 favors dual SD cards with UHS-II compatibility, providing ultrafast write speeds, while the D800 uses an older combo of CF and SD cards, limiting transfer speeds and card choice.

Price and Value Considerations

The D780 launched at approximately $2300, while the aging D800 still commands around $3000 new or on the used market due to its reputation.

For photographers seeking cutting-edge hybrid functionality with excellent image quality and better video, the D780 represents excellent value. Conversely, if ultra-high resolution and maximum detail for large prints are paramount - and 4K video or fastest burst rates are less relevant - the D800 remains compelling.
