Nikon D70s vs Nikon D750: A Deep Dive into Two Generations of Nikon DSLRs

As an enthusiast or professional stepping into Nikon’s storied DSLR lineup, two cameras often come under consideration: the venerable Nikon D70s and the more contemporary Nikon D750. These two represent different eras of photographic technology - one from the mid-2000s and the other from the mid-2010s - yet both carry Nikon’s hallmark quality and DSLR heritage. In this comprehensive comparison, we’ll explore how these models stack up across a broad range of photography disciplines and real-world scenarios, leaning on hands-on testing and technical insight to guide you toward the best choice for your needs and budget.

Design and Ergonomics: Then and Now

At first glance, the Nikon D70s and D750 are both recognizable as mid-size SLRs, but a close inspection reveals their design evolution reflecting differing priorities in handling and interface.

The D70s, released in 2005, features a compact yet robust mid-size SLR body, physically measuring 140x111x78mm and weighing about 679g (without lens). Its grip is adequate for smaller hands, though the design falls behind modern ergonomic standards with notable lack of illuminated buttons, touchscreen, or deep front grip contours. The single SD card slot (CompactFlash type), fixed 2-inch LCD screen with just 130k dots, and absence of live view further reflect the technology constraints of its time.

Conversely, the D750 (introduced in 2014) retains a similarly sized form factor at 141x113x78mm but adds heft, tipping the scales at 840g, largely due to a full-frame sensor and a more robust magnesium alloy body with weather sealing (dustproof). The larger, higher-resolution 3.2-inch tilting LCD with 1,229k dots greatly enhances usability for both stills and video composition. Controls are thoughtfully laid out with fast access dials and a top LCD screen, though it lacks touchscreen functionality. The D750’s dual SD card slots facilitate greater storage flexibility and workflow efficiency.

Ergonomically, the D750 not only offers better grip comfort and durability but also steps up with refined control customization and physical responsiveness, which benefits professional and enthusiast photographers shooting for extended periods and in diverse conditions.

Sensor Technology and Image Quality - The Heart of the Matter

A decisive differentiator between the two cameras lies in their sensor design and resultant image capabilities.

The Nikon D70s is equipped with a 6.1-megapixel APS-C sized CCD sensor measuring 23.7 x 15.5 mm (total area ~367.35mm²), supporting a crop factor of 1.5x relative to full-frame. While groundbreaking at its launch, this sensor yields modest resolution and dynamic range by today’s standards. DXOMark scores reflect an overall 50 rating with a color depth of 20.4 bits, a dynamic range of 10.3 stops, and low light ISO performance equivalent to ISO 529. This limits the D70s primarily to well-lit environments and subjects that do not require heavy cropping or large prints.

In stark contrast, the Nikon D750 sports a state-of-the-art 24.3-megapixel full-frame CMOS sensor measuring 35.9 x 24mm (sensor area ~861.6 mm²), significantly larger and more capable in capturing light. This sensor, paired with Nikon’s Expeed 4 processor, delivers exceptionally clean images with rich color (DXOMark color depth 24.8 bits), outstanding dynamic range (approximate 14.5 stops), and noise performance up to ISO 2956 native - and extendable to 51200. The full-frame format opens creative possibilities in depth-of-field control, low-light capability, and resolution for large prints or crop flexibility.

Both cameras include an optical low-pass (anti-aliasing) filter, which slightly softens fine details but reduces moiré artifacts.

This sensor difference alone positions the D750 as the vastly superior tool for advanced applications demanding high resolution, low noise, and wide tonal range, such as landscapes, portraits, and professional assignments.

Autofocus Systems and Shooting Performance

Autofocus speed, accuracy, and versatility often define practical usability, particularly in action or wildlife photography.

The Nikon D70s employs an 11-point phase-detection AF system with no cross-type points, limited selective AF modes, and no face or eye-detection capabilities. Autofocus tracking is not supported, and there is no live view AF, limiting focusing options in composition modes other than the viewfinder. Continuous shooting is capped at 3 frames per second (fps), which restricts fast-paced shooting.

The D750, meanwhile, boasts a vastly improved 51-point AF system with 15 robust cross-type sensors that enhance precision even in challenging conditions and low contrast situations. It supports face detection and continuous AF tracking modes, ideal for wildlife, sports, and portrait photography. Live view autofocus is contrast-detection based but functional. The camera shoots at 6.5 fps burst speeds, doubling the D70s, enabling better capture of decisive moments.

Our hands-on tests confirm the D750’s autofocus is consistently more reliable and able to maintain sharpness on moving subjects across various lighting conditions - an essential advantage in action or wildlife shoots.

Image Stabilization and Lens Choices

Neither camera features in-body stabilization (IBIS), a common trait for Nikon DSLRs of this period. Instead, stabilization depends on VR (Vibration Reduction) technology within compatible Nikon F-mount lenses. Both models share compatibility with the extensive Nikon F lens lineup (over 300 lenses), although the full-frame D750 supports FX lenses natively, whereas the D70s uses APS-C (DX) lenses effectively due to sensor crop.

Lens compatibility and performance differ: FX lenses deliver wider angles and natural field of view on the D750, advantageous for landscapes and architecture, while DX lenses (smaller, often lighter) suit the D70s’s APS-C sensor and can offer longer effective reach due to crop factor, benefiting wildlife and sports shooters who require telephoto magnification.

Viewfinders and LCD Displays: Framing Your Image

The viewfinder experience remains a key advantage of DSLRs, and these cameras represent significant differences.

The D70s relies on an optical pentaprism viewfinder with approximately 95% frame coverage and 0.5x magnification, leading to a slightly cropped and smaller viewing experience. A fixed 2-inch LCD screen with 130k-dot resolution offers minimal live view options and limited utility.

The D750’s pentaprism viewfinder is noticeably brighter and provides 100% frame coverage at 0.7x magnification, offering a true-to-life preview of your composition, crucial for precise framing and focus confirmation. Complementing this is the 3.2-inch tilting LCD screen with high resolution (1229k dots), enhancing versatility when shooting at awkward angles or reviewing images.

This combination on the D750 marks a significant ergonomic and usability leap, especially important during lengthy shoots or video recording.

Build Quality, Durability, and Weather Resistance

While both DSLRs fall under Nikon’s "advanced DSLR" category, their builds reveal their intended usage and longevity expectations.

The D70s features a sturdy but comparatively lighter polycarbonate body without sealing, limiting environmental robustness. It is not designed to withstand moisture, dust, or extreme conditions.

In contrast, the D750 incorporates a magnesium alloy chassis with extensive weather sealing against dust and moisture, positioning it as a reliable tool for professional outdoor and travel photographers operating in variable climates. This robustness, combined with a slightly heavier body, promises better durability and confidence.

Battery Life and Storage Practicalities

Practical photography demands depend heavily on storage and power management.

The D70s uses the EN-EL3a battery and offers modest battery life (manufacturer data suggests around 300 shots per charge, though variable), coupled with a single CompactFlash slot (Type I or II). This older storage format, while reliable at its time, is now considered bulky and slower than modern SD standards.

Meanwhile, the D750 features the EN-EL15 battery pack, with impressive real-world endurance at around 1230 shots per charge, accommodating long shooting days without frequent recharging. Its dual SD card slots support modern SDHC/SDXC media, enabling overflow storage, backup, or separate file types (JPEG/RAW) - a distinct advantage for professional workflows.

Connectivity and Video Features

Here, the cameras chart different paths, with the D70s lacking all modern connectivity as well as video capabilities.

The D70s has no wireless connectivity options (Wi-Fi, Bluetooth), no video recording facilities, and USB 1.0 data transfer speeds, which are extremely slow by today’s standards.

The D750 counters with built-in Wi-Fi for remote shooting and image transfer, USB 3.0 for fast data transfers, and HDMI output. It also includes a microphone and headphone jack, facilitating beginner to intermediate video production with Full HD (1920x1080) recording up to 60fps, encoding in H.264 MPEG-4 format. While it lacks 4K recording, the D750 provides ample video features for casual to semi-professional multimedia projects.

Handling Across Photography Disciplines

Understanding how these cameras perform across various photographic genres is key to spotting the right fit.

Portrait Photography

The D750’s full-frame sensor naturally excels at rendering pleasing skin tones with higher bit-depth color and smoother gradations. Its advanced 51-point AF with face detection ensures sharp eye autofocusing - a crucial aspect for portraits. The combination of wider aperture FX lenses plus full-frame depth-of-field control produces creamy bokeh unmatched by the D70s’s cropped sensor setup.

In contrast, the D70s, while viable for portraits, suffers from lower resolution, limited AF sophistication (no eye detection), and a narrower dynamic range, often requiring careful lighting and post-processing to achieve desirable skin tone rendition.

Landscape Photography

Dynamic range and resolution dominate landscape image quality. The D750’s 24MP full-frame sensor offers vast dynamic latitude to capture shadow and highlight detail, reducing reliance on graduated filters. Its weather sealing comforts photographers working outdoors in challenging weather. The larger sensor area allows use of wide-angle FX lenses with correct field-of-view.

The D70s, with its smaller 6MP sensor and lower dynamic range, falls short for landscape enthusiasts who demand large prints or optimal tonality but remains budget-friendly for amateurs shooting favorable lighting conditions.

Wildlife and Sports Photography

These genres rely on rapid autofocus, high frame rates, and telephoto reach.

The D750’s 51-point AF system with tracking functions and quick 6.5fps burst makes it a capable tool for capturing fast-moving subjects. Its larger sensor doesn’t crop the angle of view, potentially reducing telephoto reach, but superior AF accuracy and noise control at high ISO compensate. High ISO performance is essential in dawn/dusk wildlife shoots and indoor sports halls.

The D70s’s limited 11-point AF, no AF tracking, and 3fps burst rate restrict action photography. However, the 1.5x crop factor extends focal length effectively, working somewhat in favor for telephoto reach though at the cost of image noise and lower resolution.

Street Photography

Portability, discreetness, and low-light ability rank high here. The lighter D70s body is smaller and less obtrusive, and with fewer features to attract attention, it may appeal to street photographers seeking simplicity. Yet, the D70s’s low-light limitations and slower AF may hamper spontaneous shooting moments.

The D750, despite slightly increased weight, offers superior low-light sensitivity, reliable autofocus, and better image quality for the variety of lighting situations one encounters on the street. The tilting screen enhances flexibility for candid angles but may be a drawback if stealth is paramount.

Macro Photography

The precision of autofocus and sensor detail determine results. The D750’s higher resolution and advanced AF points enable sharp captures of macro subjects, though macro lenses with VR remain essential. Lack of built-in image stabilization requires steady technique or tripod use.

The D70s, less advanced in AF and resolution, can suffice for casual macro but with limited detail fidelity and slower focusing.

Night and Astro Photography

High ISO noise performance and long exposure capabilities are essential.

The D750 truly shines with near-clean images at ISOs above 3200 and native ISO down to 50, allowing exquisite nightscapes and astrophotography with less post-processing noise. It supports long shutter speeds up to 30 seconds and even offers time-lapse recording.

The D70s’s ISO maxes at 1600 native with noisier output; long exposure times are comparable but selectivity for stars or dark skies capture is limited.

Video Capabilities

No video on the D70s places it out of the running for modern multimedia creators. The D750's 1080p 60fps video, microphone and headphone jacks, and tilting screen make it suitable for quality video workflows, though without 4K support it is not the latest standard.

Travel Photography

Weight, battery life, lens versatility, and ruggedness count.

While the D70s is lighter and smaller, the D750’s significant battery life, rugged body, and expanded lens options provide clear advantages for travel photographers requiring versatility and reliability.

Professional Workflows

The D750’s robust RAW support, dual card slots (critical for backup), weather sealing, and connectivity make it workplace-ready. The D70s is primarily an entry-level or enthusiast-grade camera, showing its age in performance and compatibility.
