Canon EOS 7D Mark II vs Nikon D70: A Hands-On Comparison of Two Mid-Size DSLRs

In the ever-evolving landscape of digital photography, camera enthusiasts and professionals often weigh legacy models against newer generations to determine the best fit for their needs, balancing body design, image quality, and usability. Today, we look closely at two mid-size DSLRs that, despite a decade separation, continue to appeal to certain photographers: Canon's EOS 7D Mark II (announced 2014) and Nikon’s classic D70 (released 2004). Having extensively tested both cameras, I’ll share detailed insights from sensor performance through real-world handling - helping you decide which suits your photography ambitions.

First impressions matter: The Canon 7D Mark II is larger and more robust than the Nikon D70, a direct visual of their physical footprint shows.

Build and Handling: Ergonomics that Define the Experience

Even before firetrigging the shutter, the tactile experience largely determines photographer satisfaction. Both cameras belong to the "mid-size SLR" category, but as you’d expect, ergonomics have evolved significantly over the decade between their releases.

The Canon 7D Mark II measures 149x112x78mm and weighs a hefty 910g with battery, lending a reassuring heft that balances well with heavier lenses - an essential feature for wildlife and sports shooters who demand extended use without fatigue. The solid magnesium alloy body offers extensive weather sealing, shielding against dust and moisture. You can rely on this build for shooting in less-than-ideal environments.

Contrast this with Nikon’s D70 at 140x111x78mm and 679g - a lighter, more compact body aimed squarely at enthusiasts stepping up from point-and-shoots or earlier DSLRs. While it feels nimble and easy to carry, it lacks weather sealing, making it less forgiving in harsh conditions.

Another engraving of difference is control layout. The 7D Mark II sports a top panel rich in direct access buttons and dials, including a dedicated AF point selector and a top status LCD, allowing quick parameter adjustments in the heat of action. The D70’s controls, while functional, feel more spartan, with fewer custom buttons and no top display, pushing you more often into menus.

For photographers who prioritize quick, tactile control and weather resistance, the Canon clearly leads here. However, if lightweight portability and straightforward operation matter most, the Nikon still has merit.

Sensor Technology and Image Quality: A Generational Leap

In side-by-side image quality discussions, sensor performance remains the cornerstone. Here, technological evolution is readily apparent.

The 7D Mark II boasts a 20.2-megapixel APS-C CMOS sensor sized 22.4x15mm with a crop factor of 1.6x. Canon wisely integrated a dual DIGIC 6 processor setup, accelerating image processing pipelines and noise reduction algorithms. By contrast, the D70 houses a 6.1-megapixel APS-C CCD sensor measuring 23.7x15.5mm with a 1.5x crop factor. While slightly larger in surface area, the older CCD tech can only compete so much against the Canon's newer CMOS sensor.

These figures translate into meaningful practical differences. The 7D Mark II delivers a maximum image resolution of 5472x3648 pixels, far exceeding the D70’s 3008x2000 resolution. Higher pixel count means greater detail capture potential - especially critical for cropping or large prints.

Sensor specs directly influence image clarity, dynamic range, and ISO performance.

Measured by DxOMark’s industry-standard tests, the Canon achieves an overall score of 70 with color depth of 22.4 bits, dynamic range of 11.8 EV, and impressive low-light ISO performance rating of 1082. The Nikon lags with a 50 overall score, 20.4 bits color depth, 10.3 EV dynamic range, and lower ISO sensibility at 529.

In practical terms:

• Dynamic Range & Color Reproduction: The 7D Mark II captures more nuanced tones in highlights and shadows, an asset for landscape and portraiture demanding subtle gradations.

• High ISO Noise Handling: Canon's CMOS sensor retains cleaner images at ISO settings up to 16000 native (expandable to 51200). The D70 tops out at ISO 1600 native with notable noise - limiting nighttime, indoor, or action shooting under low light.

• Resolution Impact: The higher megapixel output on the 7D Mark II also benefits wildlife and macro shooters who need sharpness and cropping flexibility.

Autofocus and Performance in Action

For photographers reliant on speed and accuracy - sports, wildlife, or event shooters - the autofocus (AF) system distinguishes itself as a critical feature.

The Canon EOS 7D Mark II integrates a 65-point all cross-type autofocus system, including face detection and continuous AF tracking. This setup delivers precise focus lock and swift adjustments even in challenging lighting, maintaining consistency for fast-moving subjects. Coupled with a robust 10-frames-per-second burst rate, the 7D Mark II suits photographers who can’t afford to miss a beat.

The Nikon D70, on the other hand, offers a modest 3fps burst speed and a less sophisticated autofocus system, lacking face detection and continuous AF tracking. Its AF points are fewer and less sensitive in low contrast, restricting its suitability for fast-action capture.

The 7D Mark II’s Hybrid CMOS AF allows live view focusing with contrast and phase detection - a boon for video or tripod-based shooting; the D70 has no live view functionality at all.

This difference is palpable when shooting dynamic subjects outdoors or indoors:

• With the 7D Mark II I was able to capture a rapid series of bird flight sequences sharply within seconds.

• The D70 required more careful pre-focus and slower shooting, missing many decisive moments.

Real-World Performance Across Photography Genres

Portraiture

Portrait photographers value skin tone accuracy, pleasing bokeh, and reliable eye detection.

Canon’s 7D Mark II, paired with Canon EF and EF-S lenses, delivers excellent skin tone reproduction thanks to Canon’s proprietary color science and advanced sensor. The 65-point AF includes face and eye detection, aiding precise focus on subjects’ eyes - a must for compelling portraits.

While the Nikon D70 can produce decent portraits given good lighting, its 6MP sensor resolution limits large or detailed prints. It lacks face or eye detection autofocus, so focus precision relies heavily on user skill.

In terms of background separation, the 7D MII takes advantage of modern lenses with wide apertures; its sensor resolution allows enhanced bokeh quality.

Landscape Photography

High dynamic range and resolution shine in landscapes. The Canon’s 11.8 EV dynamic range and 20MP resolution easily outperform the older Nikon sensor’s capabilities.

Although the D70 sensor is slightly larger in area, the 7D’s newer sensor architecture yields cleaner shadows and richer highlights, preserving scene details that can be fine-tuned in post-processing.

Weather sealing and solid build make the Canon more reliable in outdoor weather changes - rain or dust. The Nikon D70's lack of environmental sealing means added caution is required when shooting in the field.

Wildlife and Sports

The demands of wildlife/formidably fast sports shooting speak to the 7D Mark II’s strengths - fast 10fps burst, robust AF tracking, and extensive lens support (over 320 EF/EF-S lenses).

In contrast, the D70’s constrained 3fps and basic AF system render it less capable for fast-moving subjects. However, for hobbyists not requiring ultra-high frame rates, it still offers a starting point.

Street Photography

Street shooters often prize compactness, low-light capabilities, and discretion.

Here the Nikon D70’s smaller size and lighter weight provide portability advantages. However, the Canon’s superior high-ISO performance and faster shutter speed (max 1/8000s) enable more creative freedom in variable lighting.

Still, the 7D Mark II’s more conspicuous design may attract attention, unlike the more understated D70.

Macro Photography

While neither camera offers specialized macro capabilities, image quality, autofocus precision, and stabilization matter.

The Canon’s superior AF system helps nail tight focus on small subjects, crucial for shallow depth-of-field macro shots. Lack of in-body image stabilization in both cameras means lens-based IS or tripod use is necessary.

Night and Astro Photography

ISO performance is key in night and astrophotography. Canon’s sensor shines here with cleaner images at high ISO values, while Nikon’s ISO ceiling seriously limits options.

Additionally, the 7D Mark II supports long exposure modes and built-in GPS for precise location tagging - a helpful feature for astrophotographers.

Video Capabilities

Video is a domain where the Canon 7D Mark II completes a generational leap.

Offering Full HD 1080p recording at up to 60fps (frames per second), microphone and headphone ports for audio monitoring, and dual DIGIC 6 processors for smooth handling - the 7D MII caters to hybrid shooters or videographers.

The Nikon D70 offers no video recording capabilities - simply reflecting the era it was designed in.

Travel Photography

Balance, weight, versatility, and battery life define a great travel camera.

The D70’s lighter weight and simpler feature set appeal to minimalist travelers, but limited low-light and resolution may frustrate serious shooters.

Conversely, the 7D Mark II’s versatility - with dual card slots, extended battery life (approx. 670 shots), and rugged body - makes it an all-rounder for travel professionals.

User Interface, LCDs, and Viewfinders

A quality viewfinder and LCD influence shooting precision and image review speed.

Both cameras sport optical viewfinders, but the Canon 7D Mark II features a pentaprism covering 100% of the frame at 0.63x magnification, providing a bright, clear view. The Nikon D70 uses a pentamirror offering 95% coverage and 0.5x magnification - noticeably dimmer and not fully representative of the image edges.

On the rear, the 7D Mark II sports a 3-inch 1040k-dot fixed LCD with live view and wide-angle viewing. Its screen allows quick composition and detailed image inspection.

The D70 includes a small, 1.8-inch LCD with 130k-dot resolution, which today looks dated and doesn’t support live view.

Rear screens: The 7D Mark II’s bright and larger display vastly outclasses the D70’s small, basic screen.

These differences affect workflow agility - important for event photographers who need fast access to settings and image review.

Lens Ecosystem and Compatibility

Both cameras use established lens mounts: Canon EF/EF-S for the 7D Mark II and Nikon F-mount for the D70.

Canon’s EF/EF-S system includes over 320 native lenses ranging from affordable primes to professional L-series zooms. Native compatibility with advanced lens features (IS, USM, STM) complements the 7D’s autofocus prowess.

Nikon’s F-mount also supports a vast lens selection (300+), including legacy glass from film days. However, with the D70’s autofocus limitations and older AF coupling, some lenses perform better than others - particularly AF-S lenses designed later.

For new buyers, Canon’s EF/EF-S mount provides a more modern and versatile lens landscape.

Battery Life and Storage

In the field, battery endurance can impact shoot duration.

The 7D Mark II uses Canon’s LP-E6N battery rated at approximately 670 shots per charge, with dual card slots (CF + SD), improving storage flexibility and data redundancy.

The Nikon D70’s EN-EL3 battery offers no official CIPA rating but is known for shorter life (estimated under 500 shots), paired with a single CF card slot.

Dual slots and longer life support professional workflows and event shooting, where the Canon has a marked advantage.

Connectivity and Extras

Both cameras miss the mark on wireless options - no Wi-Fi, Bluetooth, or NFC on either. The 7D Mark II includes built-in GPS for geotagging, a useful tool absent in the D70.

Interface-wise, the Canon offers USB 3.0 and HDMI out, enabling faster data transfer and live video monitoring. The Nikon sticks with USB 1.0 and no HDMI connections.
