At first glance, both the Nikon D700 and D810 share the hallmark mid-size DSLR footprint characteristic of Nikon's pro-oriented bodies, with robust construction and familiar handling ergonomics. The D700, announced in late 2008, weighs approximately 1074 grams and measures 147 x 123 x 77 mm, while the D810, introduced in mid-2014, is slightly lighter at 980 grams but marginally deeper with dimensions of 146 x 123 x 82 mm.

The D700’s slightly bulkier physique provides a reassuring grip favored by users with larger hands or those who prioritize a substantial feel in the hand. Conversely, the D810’s marginally more compact form - with a deeper body mainly due to updated electronics and additional features - offers improved balance when paired with heavier zoom lenses, thanks to refined ergonomics. Both bodies feature high-grade magnesium alloy construction and comprehensive environmental sealing, ensuring durability against dust and moisture, crucial for outdoor and professional use in challenging conditions.

The physical control layout also shows subtle evolution: the D810’s buttons provide crisper tactile feedback, and additional customizable controls offer enhanced workflow efficiency, particularly during extended shoots.

Design and User Interface: Controls, Viewfinder, and LCD Displays

Constructed with professional demands in mind, both cameras feature traditional optical pentaprism viewfinders, yet with notable distinctions. The D700 offers approximately 95% frame coverage at 0.72x magnification, typical for its release era, requiring photographers to anticipate slight framing adjustments when previewing shots. Meanwhile, the D810 boasts 100% frame coverage and improved 0.7x magnification, providing a critically accurate and immersive view that facilitates precise composition, critical in landscape or studio work where edge-to-edge accuracy is paramount.

Moving to rear LCDs, the D700’s 3-inch TFT color LCD offers 922,000 dots with wide viewing angles but lacks touch capabilities, consistent with its 2008 design philosophy. The D810 upgrades to a slightly larger 3.2-inch TFT-LCD with a WRGB pixel structure yielding about 1,229,000 dots. This translates into sharper image previews and easier highlight recovery during playback review. Both cameras eschew touchscreens, reflecting Nikon’s preference at these levels for button and dial-based operation - a plus for users who prefer tactile control over finger swipe interfaces.

The D810 also includes an improved top LCD panel with more convenient illumination and control over shooting parameters, making it easier to verify settings in dim light.

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

The sensor is where the Nikon D810 truly distinguishes itself from the older D700. The D700 features a 12.1-megapixel, full-frame CMOS sensor equipped with a conventional optical low-pass anti-aliasing (AA) filter. While its limited resolution by modern standards restricts cropping potential and large print sizes, its comparatively larger photosites provide solid signal-to-noise ratios, yielding excellent performance at base and mid-range ISO settings (native ISO from 200–6400, expandable to 100–25,600). This makes the D700 a strong choice for photographers prioritizing low-light reliability and fast post-processing.

Conversely, the Nikon D810 employs a 36.3-megapixel full-frame CMOS sensor without an AA filter, enabling superior resolution and sharpness ideal for landscape, studio, and commercial photographers demanding intricate detail reproduction. It also has an extended ISO range from 64 up to 12,800 natively (expandable to ISO 32–51,200), delivering remarkable dynamic range of approximately 14.8 stops as measured by DxO Mark, significantly enhancing highlight recovery and shadow detail in post-processing.

The absence of an AA filter in the D810 can introduce potential moiré patterns in certain textile or repetitive pattern scenarios, but Nikon’s advanced processing algorithms and higher pixel density mitigate this effectively in most shooting conditions.

In practical testing across ISO ranges, the D810’s superior sensor exhibits finer gradation, richer color fidelity (25.7 bits color depth vs. 23.5 bits on D700), and higher usable ISO before noise degrades images, making it substantially more versatile for challenging lighting situations.

Autofocus Systems: Speed, Accuracy, and Tracking

Both the D700 and D810 harness Nikon’s renowned Multi-CAM phase detection autofocus system with 51 points, offering robust focusing capability. However, the D810 integrates the Multi-CAM 3500FX II autofocus module, compared to the older Multi-CAM 3500FX in the D700, providing 15 cross-type sensors versus an unconfirmed count in the D700 model but known to be fewer cross-type points.

This upgrade, combined with enhanced autofocus algorithms, renders the D810 vastly superior in autofocus performance - especially autofocus tracking, where the D810 incorporates 3D tracking to lock onto moving subjects with increased accuracy. The D700 supports continuous AF but lacks this advanced tracking, making it less competitive for fast-action subjects.

Live view autofocus is comparable and manual focus remains equally viable on both, benefiting from wide compatibility with Nikon’s extensive F-mount lens lineup.

This difference is most noticeable in action photography workflows - sports, wildlife, and street shooting frequently demand rapid, reliable tracking that the D810 handles more effectively.

Burst Shooting and Buffer Depth

Both cameras cap continuous shooting at approximately 5 frames per second - a respectable rate in their respective eras but modest compared to modern professional standards. The D810, however, offers a more generous buffer due to faster processing and higher-speed UDMA CompactFlash and SD card support (it uniquely supports dual card slots), meaning it maintains sustained burst shooting longer without slowdown.

The D700, while dependable, can fill its buffer rapidly, especially capturing RAW files, which may impose limits when tracking fast-moving sequences.

Build Quality, Weather Sealing, and Durability

Ruggedness is critical for DSLRs intended for professional or field use. Both bodies feature magnesium alloy chassis with comprehensive environmental sealing against dust and moisture ingress. Neither camera is officially waterproof or freezeproof but can withstand adverse weather when paired with weather-sealed lenses.

The D810, benefitting from newer manufacturing improvements, exhibits slightly enhanced sealing and weather resistance, a consideration if working extensively outdoors or in inclement conditions.

Both models utilize Nikon’s venerable F-mount, compatible with an expansive array of over 300 lenses ranging from affordable primes to professional-grade telephotos and specialty optics. This compatibility is a significant advantage, permitting users to invest in high-quality glass without forced obsolescence.

However, it’s important to remember that the D700’s focus motor system requires lenses with built-in motors (AF-S or AF-P) for autofocus; similarly, the D810 supports full autofocus compatibility with modern lenses, plus superior exposure metering with advanced G and E-type lenses.

For macro photographers, both depend primarily on external macro lenses; neither body features specialized macro focusing enhancements beyond what the lens provides.

Battery Life and Storage Solutions

The D700 relies on the EN-EL3e battery pack, typically rated around 1000 shots per charge under CIPA standards. The D810 uses the newer EN-EL15 battery, achieving approximately 1200 shots per charge - slightly better endurance to sustain prolonged field shooting.

Storage media also differs considerably: the D700 employs a single CompactFlash Type I slot, a solid but somewhat antiquated format by today’s standards, whereas the D810 integrates dual slots (one SD SDHC/SDXC and one UDMA CompactFlash slot), facilitating flexible backup, overflow, or raw+JPEG workflows favored by professionals.

Connectivity and Video Capabilities

Here is where the two cameras radically diverge. The D700 predates widespread demand for video recording, offering no video capabilities whatsoever. In contrast, the D810 introduces full HD 1080p video at up to 60 frames per second, with support for MPEG-4/H.264 compression, external microphone and headphone jacks for professional audio control, and HDMI output for external monitors or recorders.

While the D810’s video specs do not reach 4K resolution - reflecting its 2014 design timeframe - they provide a significant creative expansion over the D700, allowing hybrid shooters to capture high-quality stills and complementary video without switching gear.

Wireless connectivity is modest on both; the D810 supports optional WU-1b wireless adapters for image transfer and remote control, whereas the D700 lacks any built-in wireless features.
