Canon 90D vs Nikon D750: A Hands-On Comparison for the Discerning Photographer

Selecting the right DSLR is a crucial choice for both photography enthusiasts and seasoned professionals. Canon’s 90D and Nikon’s D750 have been favorites in the advanced DSLR space, albeit from slightly different eras and with distinctive feature sets. After extensive in-field testing and technical analysis, I’m here to provide a detailed, hands-on comparison that addresses real-world usage, sensor performance, ergonomics, and suitability across major photography genres.

Let’s embark on this data-driven yet experience-rich journey to help you make an informed decision - no marketing fluff, just honest, tested insights.

First Impressions: Size, Build, and Handling

When you first pick up the Canon 90D and Nikon D750 side by side, differences in their physical stature and ergonomics are immediately apparent.

The Nikon D750 carries the heft and feel of a full-frame DSLR, weighing in at 840g with robust environmental sealing. Its larger grip and broader chassis (141x113x78mm) deliver a reassuring presence, especially for users accustomed to full-frame cameras. The Canon 90D, by contrast, embraces a more compact APS-C form factor (141x105x77mm) with a weight of just 701g, making it noticeably lighter and easier to carry for extended shoots or travel.

Both bodies exhibit excellent build quality consistent with their class, featuring weather sealing to withstand dust and moisture - though per manufacturer specs, the Nikon edges slightly ahead with dust proofing explicitly noted.

Ergonomically, the Nikon D750’s grip is deeper and perhaps better suited for larger hands or when using hefty tele lenses, while the 90D’s controls feel more suited for agility and quick handheld shooting.

Examining the control layouts from the top reveals that Canon’s 90D favors a traditional modern Canon design with a slightly more compact top plate and a more forward-placed shutter release. Nikon’s D750 incorporates a slightly larger top LCD screen, providing quick glance information - a feature the Canon lacks. Canon offsets this with a fully articulated touchscreen on the back (covered later), while the Nikon sticks to a tilting but non-touch display.

These physical and interface choices are not just about feel but workflow - you’ll want to consider which better suits your shooting style and hand size.

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

The heart of any camera is its sensor, and here the Canon 90D and Nikon D750 tell very different stories:

• Canon 90D: Features a 32.5MP APS-C CMOS sensor, measuring 22.3x14.9mm. The 33MP resolution allows for impressive crop flexibility and detailed images, though the smaller sensor size means a 1.6x crop factor - a boon for telephoto reach but a challenge for wide-angle framing. The sensor uses a traditional anti-aliasing filter which slightly softens images but reduces moiré artifacts.

• Nikon D750: Sports a 24.3MP full-frame (35.9x24mm) CMOS sensor without an anti-aliasing filter, delivering superb detail, dynamic range, and superior low-light performance. The larger sensor captures more light per pixel, enhancing image quality in challenging conditions, though the 6MP lower resolution compared to the 90D means somewhat less cropping latitude.

In field tests, the Nikon D750’s sensor shines in landscape and portrait scenarios, delivering smoother tonal gradations, greater dynamic range (per DxOMark score of 14.5 EV), and cleaner high ISO images even beyond ISO 3200. The 90D, however, offers high megapixels that benefit wildlife and sports shooters who want to crop in tight without losing detail - and its native ISO range up to 25600 is respectable though noisier at higher values.

Color depth is excellent on both, with Nikon’s 24.8 bits slightly edging Canon’s generally strong output. Canon’s DIGIC 8 processor also lends improved image processing speed and noise reduction.

For photographers prioritizing ultimate image quality, especially in low light or heavy post-production workflows, the Nikon D750 generally wins. But if you prefer high-resolution files for tight crops or printing large, the Canon 90D’s sensor is compelling in an APS-C package.

Autofocus and Performance: Speed, Accuracy, and Tracking

Autofocus systems can make or break the shooting experience, especially in fast-paced genres like sports and wildlife.

Canon 90D:

• Uses a 45-point all cross-type phase-detection AF system.
• Includes Dual Pixel CMOS AF in live view, enabling smooth, fast, and accurate focus for video and stills.
• Eye detection is available, aiding portrait shooters.
• Offers continuous shooting up to 11fps, an impressive spec for the genre.

Nikon D750:

• Employs an older but reliable 51-point AF system, with 15 cross-type sensors centered.
• Phase-detection AF works brilliantly through the optical viewfinder; however, live view AF relies on contrast detection, which is slower.
• Continuous shooting bursts up to 6.5fps, decent but not class-leading anymore.
• Lacks integrated eye detect autofocus.

In practice, Canon’s more modern AF system coupled with the DIGIC 8 processor carries a clear advantage in speed and tracking, especially for wildlife and sports photographers heavily reliant on fast-moving subjects. The higher fps rate also allows capturing multiple decisive moments in rapid succession.

Nikon’s D750 autofocus remains accurate and trustworthy, particularly in standard shooting and portraiture, but can struggle in low contrast or fast action compared to the Canon.

LCD Screens and User Interface: Touchscreen vs Traditional Precision

User interface is often underrated - yet it can make daily shooting far more comfortable or frustrating.

The Canon 90D’s 3-inch, fully articulated touchscreen (1040k dots) is a huge plus for videographers and photographers who rely on flexible angles. Touch capabilities extend to AF point selection, menu navigation, and image playback zooming - making the user experience much more intuitive, especially for those stepping up from mirrorless or smartphone workflows.

The Nikon D750’s 3.2-inch tilting LCD (1229k dots) offers clearer resolution and slightly more screen real estate but lacks touch responsiveness. While solid, the reliance on buttons and dials for menu navigation is slightly more cumbersome in fast-changing environments.

If you’re shooting video, vlogging, or working in live view often, Canon’s articulating touchscreen adds undeniable operational ease.

Lens Ecosystem and Compatibility: Choice Meets Legacy

Lens selection is fundamental for most photographers, and here the mounts dictate your options.

• Canon 90D mounts Canon EF and EF-S lenses - covering the extensive DSLR lens lineup, including upwards of 326 native lenses (counting third-party offerings). The EF-S mount specifically provides access to a wide range of relatively affordable APS-C optimized options.

• Nikon D750 mounts Nikon F-mount lenses, supporting both FX (full-frame) and DX (APS-C) glass. Nikon boasts a slightly broader standard DSLR lens array as well, with around 309 compatible lenses. Full-frame FX glass unlocks the sensor’s full potential, though some specialty DX lenses offer affordability.

Practically, both cameras have wealth of options - but if you are already invested in either Canon or Nikon lens ecosystems, sticking to your brand makes sense. Third-party lens manufacturers like Sigma and Tamron equally support both mounts well.

Battery Life and Storage: Shooting Sustained or on the Go

No photographer wants to be sidelined by power or file storage.

• Canon 90D’s LP-E6N battery delivers roughly 1300 shots per charge, using CIPA standards, or longer in eco modes. Its single card slot supports SD/SDHC/SDXC UHS-II cards.

• Nikon D750’s EN-EL15 battery claims a similar 1230 shots per charge but with the advantage of a dual SD card slot for overflow, backup, or RAW+JPEG split recording - a big plus in professional settings.

The 90D benefits from modern USB charging with Power Delivery (PD) compatibility, offering convenient in-field recharging options, whereas the D750 depends on external chargers.

Video Capabilities: 4K and Beyond

If video is a secondary or primary use case, the two diverge notably.

• Canon 90D offers UHD 4K recording at 30fps, 120 Mbps locked to 1.6x crop, with MP4/H.264 compression, plus headphone and microphone jacks. Dual Pixel AF remains smooth and reliable for video, making it suitable for hybrid shooters.

• Nikon D750 restricts video recording to Full HD 1080p up to 60fps, also with mic and headphone ports. No 4K means less flexibility in cropping or high-res delivery.

For content creators, the Canon offers the more modern and versatile video feature set.

Environmental Sealing and Build Reliability

Both cameras share weather sealing, essential for demanding outdoor use. Neither is explicitly waterproof, crushproof, or freezeproof, but their robust designs protect against dust and moisture typical in adventurous shoots.
