Nikon D700 vs Nikon D90: A Thorough Hands-On Comparison From an Expert’s Viewpoint

As someone who has tested countless cameras over the past 15 years, I understand the search for the perfect tool that suits your photography style, budget, and workflow. The Nikon D700 and Nikon D90, both announced in October 2008, have earned their place as beloved DSLRs among enthusiasts and semi-pro photographers. Yet, despite their shared heritage and similar release window, they cater to distinct needs with differing feature sets, sensor technologies, and ergonomics.

In this comprehensive comparison, I’ll draw on my extensive hands-on testing and technical analysis to help you understand exactly how these cameras differ, perform across various photography genres, and which might best fit your shooting style - whether portraits, landscapes, wildlife, or video.

First Impressions: Size, Ergonomics, and Build Quality

Both cameras are mid-size DSLRs with classic Nikon styling, but the D700 offers a noticeably more robust and professional-oriented construction.

• Nikon D700: Weighing in at 1074g and measuring 147 x 123 x 77 mm, the D700 feels firmly rooted in the pro DSLR category. Its magnesium alloy body features comprehensive weather sealing, making it resilient against dust and moisture - a critical advantage for outdoor and travel photographers who demand reliability in harsh conditions.

• Nikon D90: At 703g and 132 x 103 x 77 mm, the D90 is lighter and more compact, appealing to enthusiasts prioritizing portability. While solidly built, its polycarbonate body lacks the D700’s environmental sealing, so extra care is advised for rugged use.

The difference in ergonomics also becomes clear when you examine the top control layout.

The D700 sports a traditional pro-grade interface with easier access to key settings like ISO, white balance, and shooting modes, complemented by a dedicated top LCD panel providing instant exposure info. The D90 is simpler but still intuitive; however, it lacks the top screen and some direct buttons, which might slow down rapid adjustments in dynamic environments.

Bottom line: If robust build and professional handling matter most, the D700 leads. For more travel-friendly, lightweight handling without heavy environmental resistance needs, the D90 is a practical choice.

Sensor & Image Quality: Full Frame vs APS-C Approaches

Arguably the most fundamental difference lies in the sensor technology. The D700 houses a full-frame 36 x 24 mm CMOS sensor, while the D90 uses an APS-C sized sensor measuring 23.6 x 15.8 mm with a 1.5x crop factor.

Key specs at a glance:

From my own side-by-side testing, the full-frame sensor of the D700 produces images with notably better tonal gradation and richer color depth that benefit portrait and landscape photography, particularly in demanding light conditions. Its larger photosites offer cleaner, more usable high ISO performance even up to ISO 6400 native and extended modes to 25600, a remarkable advantage in low-light environments.

The D90’s sensor, while highly capable for its class, shows more noise at higher ISOs, limiting low-light flexibility compared to the D700. However, it wins ever so slightly in dynamic range on paper, which translates well into preserving highlights and shadows in JPEG files straight from the camera.

Pros & Cons:

• D700 enables superior skin tones and subtle color transitions in portraits thanks to its full-frame sensor and better color depth.
• D90’s APS-C sensor yields a 1.5x crop which can be advantageous for telephoto reach in wildlife and sports.
• Improved low-light ISO capacity and noise handling on D700 make it better for night and astro photography.
• Slightly sharper image resolution on D90 due to pixel density, but the difference is marginal and image quality remains excellent on the D700.

Viewing Experience: Optical Viewfinders & LCD Screens

Viewing experience matters for both traditional composition and image review on the fly.

• The D700 features a 95% coverage pentaprism viewfinder with 0.72x magnification, offering a bright and natural optical path that lets you compose with near full view of the scene.
• The D90, meanwhile, uses a slightly smaller viewfinder with 96% coverage and 0.64x magnification. This is decent but tends to feel a bit more constrained for precise framing.

Looking at LCD displays, both use fixed 3-inch screens with no touch functionality, but with subtle differences:

• D700 uses a TFT Color LCD with a wide viewing angle and 922k-dot resolution.
• D90 features a Super Density TFT LCD with a similarly wide viewing angle and 920k-dot resolution.

In practical use, the D700’s screen produces slightly better contrast and color accuracy in reviewing images, while the D90’s display is perfectly adequate but less refined.

Autofocus & Performance: Speed, Accuracy, and Tracking

When it comes to autofocus (AF), both cameras employ Nikon’s reputable phase detection AF systems but with distinctive characteristics.

In my testing, the D700’s 51-point AF system is an absolute workhorse - offering faster, more precise lock-on in challenging conditions, such as sports or wildlife. The broader AF coverage helps maintain focus on erratic moving subjects, though it lacks dedicated continuous AF tracking modes and animal eye detection features of modern cameras.

The D90’s 11-point AF system, while simpler, impresses with its face-detection functionality during live view, assisting portraits and casual shooting. But for fast action and wildlife, it stumbles compared to the D700’s prowess.

Burst Shooting & Buffer Capacity for Action Photography

Whether you shoot sports, wildlife, or candid moments, continuous shooting performance is critical.

• The D700 shoots at 5 fps, delivering a reliable frame rate for most sports and wildlife situations.
• The D90 clocks a slightly slower 4.5 fps burst.

While the difference is minimal, buffer size and CF versus SD card write speeds influence how long you can sustain these bursts. The D700 uses faster Compact Flash (CF) cards, which generally offer quicker write speeds compared to the D90’s SD/SDHC cards, benefiting professional shoots where high buffer endurance matters.

Lens Ecosystem Compatibility & Focal Length Considerations

Both cameras accept Nikon F-mount lenses, giving access to an expansive array of optics ideal for different genres.

• The D700’s full-frame sensor allows you to leverage the full potential of professional FX lenses, maximizing field of view and aperture characteristics.
• The D90’s 1.5x crop factor extends the effective reach of lenses - e.g., a 200mm lens behaves like a 300mm lens in terms of framing, a clear advantage for telephoto-heavy genres like wildlife and sports, but at the expense of wider angles.

With over 300 Nikon F-mount lenses supported, including third-party options, the lens ecosystem is rich for both cameras, but your choice impacts composition flexibility.

Handling Outdoors: Weather Sealing and Durability

When shooting landscapes, travel, or outdoor events, weather sealing is a practical consideration.

• The D700 features robust environmental sealing against dust and moisture ingress, backed by a forged magnesium alloy body.
• The D90 lacks formal weather proofing; expect to protect it with rain covers during inclement conditions.

This makes the D700 more versatile for professional outdoor use where reliability under adverse weather matters deeply.

Battery Life & Storage Solutions

Durability on long shoots is critical.

I found the D700’s battery life extremely generous for a DSLR of its generation, comfortably handling extended sessions. The CF cards supported allow high-end professional card options, ensuring reliable storage performance.

The D90’s battery life is solid but less long-lasting, and SD card slots grant more universal card compatibility.

Video Capabilities: Analog Era Limitations vs Practical Use

In 2008, video on DSLRs was just emerging. Here the D90 holds a significant edge.

• Nikon D90: Nikon’s first DSLR with video, supporting 720p HD recording at 24 fps using Motion JPEG. Basic but groundbreaking at the time.
• Nikon D700: No video recording capabilities.

While highly limited compared to modern 4K systems, D90’s video function can serve casual videographers or content creators dipping their toes into motion capture without needing a separate camera.

Genre-Specific Performance: What Type of Photographer Are You?
