Canon 70D vs Nikon D750: A Hands-On Comparison for the Serious Photographer

Choosing your next camera is always a journey - balancing features, price, usability, and image quality. Today, I’ll walk you through a detailed comparison between two notable DSLRs from Canon and Nikon: the Canon EOS 70D and the Nikon D750. Despite being announced just under a year apart in mid-2010s, these cameras target quite distinct segments. My goal is to provide you with practical insights drawn from years of photography experience and rigorous camera testing, to help you decide which model fits your photographic ambitions.

First Impressions: Handling and Build - Size Matters?

At first glance, neither camera is “compact” by modern mirrorless standards, but ergonomics and size tell a compelling story. The Canon 70D, announced in October 2013, is a mid-size DSLR designed with enthusiasts and advanced amateurs in mind. Weighing 755g and measuring 139x104x79 mm, it feels relatively lightweight and nimble in your hands. Contrastingly, the Nikon D750, revealed in September 2014, is a full-frame powerhouse, coming in at 840g and slightly larger dimensions of 141x113x78 mm.

What strikes me about the Canon 70D is its grip comfort and carefully balanced body for extended handheld shooting, especially useful for street and travel photographers valuing portability. The D750’s bigger heft isn’t overwhelming but noticeably sturdier and reassuring - ideal for professional or serious hobbyist work where durability matters.

The 70D is built with some degree of weather sealing, helpful but not foolproof, while the D750 ups the ante with a sealed/chambered body officially rated dust-resistant and more robust against environmental challenges. Neither is waterproof or shockproof, so you’ll need care in extreme conditions regardless.

Both cameras maintain the classic DSLR-style optical pentaprism viewfinder - vital for photographers who prefer optical through-the-lens framing and tracking. The D750’s viewfinder covers 100% of the frame with 0.7x magnification compared to the 70D’s 98% coverage and 0.6x magnification, meaning the D750 provides a marginally more immersive view - especially beneficial when precisely composing shots in landscapes or architectures.

When it comes to top-panel controls, both cameras offer direct access to essential shooting modes and settings, but the 70D’s touchscreen LCD lets Canon sneak some more modern UI convenience for quick focus point selection and menu navigation.

Sensor Tech and Image Quality - The Heart of the Matter

One of the clearest distinctions between these two lies in sensor size and capability.

The Canon 70D sports a 20-megapixel APS-C sized CMOS sensor (22.5 x 15mm). The smaller sensor crops the field of view by a factor of 1.6x, effectively extending your telephoto reach but narrowing wide-angle potential.

In contrast, the Nikon D750 features a 24-megapixel full-frame CMOS sensor (35.9 x 24mm), which is more than double the sensor area of the 70D. This larger sensor inherently gathers more light, giving the D750 advantages in dynamic range, low-light performance, and color depth.

Let’s look at measurable scores from DxOMark, a respected industry standard for sensor analysis:

• Overall Score: D750 - 93 / 70D - 68
• Color Depth: D750 - 24.8 bits / 70D - 22.5 bits
• Dynamic Range: D750 - 14.5 EV / 70D - 11.6 EV
• Low Light ISO: D750 - 2956 / 70D - 926

These figures underscore the D750’s clear edge in delivering cleaner images with better tonal gradation, especially in challenging lighting like shadow/highlight recovery. For portrait and landscape photographers valuing rich color fidelity and flexible post-processing latitude, the D750’s sensor holds a significant advantage.

Having personally tested both cameras, I observe the 70D produces sharp, punchy images with respectable noise control up to ISO 3200, but noise becomes more noticeable beyond that. The D750 keeps usable images up to ISO 6400 and beyond, valuable for event photographers or night shooters.

Autofocus Systems - Keep Your Subjects Sharp and In Focus

Autofocus can make or break a shoot, especially in dynamic genres like wildlife and sports. Here, the Nikon D750 enjoys a more sophisticated AF system with 51 focus points, including 15 cross-type sensors that read contrast on both axes for higher accuracy. The Canon 70D has 19 focus points - all cross-type, which was innovative at its release but still modest by modern standards.

Both cameras offer face detection AF during live view and video, but neither supports modern animal eye recognition autofocus - something later models have remedied.

Continuous autofocus speed and tracking are noticeably better on the D750. When photographing wildlife or sports, the D750’s more sensitive and denser AF points allow easier tracking of erratic movement, better focus lock, and fewer missed shots.

That said, the Canon 70D still delivers a reliable AF experience for casual fast action and portrait work. When paired with Canon’s extensive EF/EF-S lens lineup (326 kits and counting), it’s a versatile performer, especially given the option for touchscreen AF point selection, which speeds up focusing in live view - a favorite feature of mine for macro and video work.

Shooting Speed and Buffer Performance

Both cameras offer decent continuous shooting rates:

• 70D: 7.0 frames per second (fps)
• D750: 6.5 fps

Though the 70D is a bit faster on paper, the D750’s buffer is larger and supports 14-bit RAW capture, which avoids bottlenecks during extended bursts. In practical use, for pro sports or wildlife shooting, I prefer the D750’s consistency in writing files and retaining focus tracking over longer bursts despite its slightly lower fps.

Screen and Viewfinder Features - Composing Your Shot

Let’s take a look at their rear displays, which some may feel are overlooked but deeply affect how you shoot in live view or review images.

The Canon 70D features a fully articulating 3.0-inch Clear View II TFT touchscreen with 1,040k dots resolution. The articulating hinge enables creative shooting angles - high, low, or even selfie-friendly compositions (yes, the 70D is selfie-friendly!). Touch AF and menu navigation feel responsive and intuitive, making the 70D popular among vloggers and hybrid shooters.

On the other hand, the Nikon D750 sports a larger 3.2-inch tilting screen with a higher 1,229k dot resolution but lacks touchscreen functionality. While not as flexible physically as a fully articulating screen, it still allows convenient positioning for awkward angles without compromising the clean, vibrant display quality.

For photographers prioritizing video work or diverse live view shooting positions, the Canon 70D’s screen edges out the D750. However, the D750’s clarity and size remain excellent for image playback and menu operation.

Video Capabilities - Who’s Better for Moving Pictures?

Neither camera supports 4K recording - a sign of the times, given their release dates in the mid-2010s - but both deliver respectable Full HD video.

• Canon 70D: Offers 1080p recording up to 30 fps, 720p at 60 fps, with H.264 compression. Includes a microphone input, and the articulating touchscreen greatly enhances focusing during video. Notably, the 70D was one of the first DSLRs to feature Canon’s Dual Pixel AF technology, which provides smooth and reliable continuous autofocus during video - immensely helpful for solo shooters.

• Nikon D750: Offers 1080p video at up to 60 fps and 720p at 60 fps, with MPEG-4 and H.264 formats. It features both microphone and headphone jacks for advanced audio monitoring and control - a big plus for videographers requiring sound fidelity. The autofocus during video, however, is contrast-detection based and less smooth/faster compared to Canon’s Dual Pixel AF.

Dear Canon, please bring Dual Pixel AF to a successor with 4K someday! For now, if video is a key priority, the 70D surprisingly outpaces the D750 in autofocus ease, despite limitations like lower bit rates.

Lens Ecosystem and Compatibility - Your Creative Toolbox

Both Canon and Nikon have extensive lens lineups, but their ecosystems differ by mount and generation.

• Canon 70D: Uses the EF/EF-S mount, compatible with hundreds of lenses ranging from affordable third-party primes to pro-grade L-series zooms. Canon’s vast and mature system ensures you can find optics for portraits, macro, wildlife telephoto, and everything in-between without compromise.

• Nikon D750: Uses the Nikon F mount, incredibly versatile from decades of Nikkor classics up to modern AF-S lenses. The full-frame sensor benefits from dedicated FX glass for edge-to-edge sharpness. Though fewer in number compared to Canon EF/EF-S lenses, Nikon’s FX lineup is revered for optical quality and reliability.

In my experience, both systems have enough choices to serve any genre you want. If budget is tight, Canon’s massive range of affordable EF-S lenses can help you build a kit incrementally, while the D750 might push you toward pricier FX primes for best results.

Battery Life and Storage - Staying Power in the Field

• Canon 70D: Rated for about 920 shots per charge (using LP-E6 battery), suitable for typical daily shooting or events but may require a spare battery for long outings.

• Nikon D750: Rated for an impressive 1,230 shots per charge (using the EN-EL15 battery), providing extended operational time - ideal for travel, weddings, or sports events where charging chances are minimal.

Also, note the critical difference in memory card configuration:

• Canon 70D houses a single SD/SDHC/SDXC card slot.
• Nikon D750 offers dual card slots (both SD/SDHC/SDXC), a valuable feature for professional reliability - allowing instant backup or separation of RAW and JPEG files.

For pros and enthusiasts shooting in demanding environments, the D750’s dual slots and longer battery life win hands down.

Connectivity and Extras

Both cameras have built-in Wi-Fi for image transfer and remote control, though these early Wi-Fi implementations are not as seamless as today’s mirrorless models. Neither supports Bluetooth or NFC, limiting instant sharing ease.

The D750’s USB 3.0 port allows faster data transfer compared to the 70D’s slower USB 2.0, a small but useful difference when offloading large RAW files.
