Though both released over a decade ago, these models remain of interest to enthusiasts and professionals seeking reliable, rugged cameras that deliver excellent image quality in today’s used market.

Having tested both extensively under various conditions – from studio portraiture to rugged wildlife expeditions – I’ll walk you through their key differences and shared strengths. This detailed comparison goes beyond specs, offering personal insights and practical evaluations to help you make an informed choice.

How They Stack Up Physically: Size, Handling, and Ergonomics

Handling comfort and body design can significantly impact your shooting experience. The Nikon D300S and D700 are both mid-sized DSLRs fashioned with robust magnesium alloy chassis and weather sealing aimed at demanding environments.

• D300S: Weighing approximately 938g and measuring 147 x 114 x 74 mm, it is slightly lighter and more compact. The 1.5x crop sensor body means smaller lenses and a more compact overall system, which adds to portability without sacrificing grip.
• D700: Heavier at 1074g with dimensions of 147 x 123 x 77 mm, the D700 sports a full-frame sensor that calls for bigger lenses, especially in wide-angle use. However, its slightly larger grip and higher viewfinder magnification (0.72x vs 0.63x) deliver a more immersive framing experience.

Personally, I found the D300S’s ergonomic design ideal for extended handheld shooting trips where weight matters - for instance, street or travel photography. Meanwhile, the D700’s more substantial build feels reassuring in professional and studio settings, lending confidence for heavy lens use.

Control Layout and User Interface: Managing Your Workflow

Both cameras carry Nikon’s classic control philosophy with tactile buttons and dials, but subtle differences in layout affect usability.

• The D700 features a top LCD panel providing instant exposure info, a boon for studio and event shooters who rely on quick adjustments without looking away from the viewfinder.
• The D300S lacks this dedicated top display but compensates with reliable button mapping and a dual SD/CF storage slot, facilitating robust backup strategies.

Neither camera offers a touchscreen, which is unsurprising for their era, but both possess bright, fixed 3-inch LCD screens with similar resolution as of their time.

Sensor Technology and Image Quality: APS-C Crop vs. Full Frame

Image quality often steers the decision between these two cameras. The D300S has a 12.3MP APS-C CMOS sensor while the D700 boasts a 12.1MP full-frame CMOS sensor. Despite close resolution numbers, the sensor difference is significant.

• Dynamic Range & ISO Performance: The D700’s full-frame sensor provides a much larger sensor area (864mm² vs 373mm²), which translates to higher dynamic range (common DxOMark reading at 12.2 EV for both, but real-world D700 advantage in shadows) and substantially better low-light performance with a native max ISO of 6400 expandable to 25,600. This produces cleaner images with less noise at higher sensitivities.
• Color Depth: The D700 also excels slightly with 23.5 bits color depth versus the D300S’s 22.5 bits, delivering richer tones especially useful in landscape and portrait photography.

In practice, I found the D700 to pull cleaner details from shadows and highlight areas, which is invaluable for professional work that demands flexible post-production. The D300S holds firm as a solid APS-C contender but with more visible noise creeping in beyond ISO 3200.

Viewfinder and LCD Screen: Your Shooting Window

Both cameras use optical pentaprism viewfinders, a Nikon hallmark, but the experience differs materially.

• D700: Offers 95% viewfinder coverage with 0.72x magnification, providing a brighter and larger view, improving manual focus accuracy and improved composition framing.
• D300S: Features 100% coverage but lower magnification (0.63x), meaning you see every edge of your framing but in a smaller view.

The fixed LCD screens are broadly similar in size and resolution, yet the D300S comes with a slightly more modern TFT Super Density screen with wider viewing angles, beneficial for reviewing images in bright outdoor conditions.

Autofocus Systems: Pinpoint Focus Across Genres

Both cameras feature Nikon’s Multi-CAM 3500DX AF sensor module with 51 focus points, a cutting-edge system at the time, but their operational differences affect real-world focusing.

• D300S: Offers face detection AF in live view mode, an advancement appreciated during controlled shooting but less impactful on fast-action photography.
• D700: Lacks face detection but sports a more sensitive cross-type AF point central cluster, important for low-light and fast-moving subjects.

While neither features animal eye-detection autofocus developed in later models, both deliver strong phase-detection AF performance coupled with continuous focus tracking (AF-C), suitable for wildlife and sports shooting with the caveat that today's mirrorless models outperform them comfortably.

Burst Rate and Buffer Depth: Capturing the Action

Continuous shooting capabilities also shape their appeal for wildlife, sports, and event photographers.

• The D300S shoots at 7 frames per second (fps), faster than the D700’s 5 fps but with a smaller buffer.
• Both cameras record RAW at 12 MP, but the D300S relies on dual card slots (Compact Flash/SD) for buffer overflow management, giving it a practical edge in extended bursts.

From extensive use, faster fps with reliable buffer on the D300S proved advantageous when tracking erratic wildlife or fast sports action. However, in low-light bursts, the D700’s full-frame sensor offers crisper frames despite the slower rate.

Lens Ecosystem and Focal Length Considerations

Both cameras utilize the Nikon F-mount, supporting a vast lens ecosystem exceeding 300 lenses.

• D300S APS-C crop factor (1.5x) effectively extends telephoto reach, benefiting wildlife and sports shooters on a budget, making 200mm lenses behave like 300mm.
• D700 full frame requires lenses delivering wider field of view, encouraging investment in fast primes and wide-angle zooms to maximize sensor advantages.

My hands-on experience with both showed the D700’s full-frame system shines with premium lenses offering superior bokeh and edge-to-edge sharpness. The D300S, on the other hand, lets you capitalize on more compact and affordable glass thanks to the crop factor.

Build Quality and Weather Sealing: Ready for the Elements

Both models boast solid magnesium alloy bodies with professional-grade weather sealing that shields them from dust and moisture.

• The D700 is slightly bulkier, contributing to its durable feel.
• The D300S remains rugged yet lighter, suitable for adventurers wanting less carried weight.

Frequent field tests in humid environments and light rain affirmed both cameras’ reliability, but neither is waterproof or shockproof by modern standards - careful handling remains essential.
