Feature-by-Feature Breakdown
Sensor Resolution
- Canon Eos R: Features a 30.3-megapixel full-frame CMOS sensor. This provides excellent detail and low-light performance, ideal for professional portraits and landscapes. However, it might be overkill for casual users and can result in larger file sizes.
- 90d: Boasts a 32.5-megapixel APS-C CMOS sensor. This higher pixel count on a smaller sensor can lead to impressive detail and cropping flexibility. The APS-C format also offers a “reach” advantage for telephoto shooting, but low-light performance may not be as strong as full-frame.
- Winner: 90d
Autofocus System
- Canon Eos R: Equipped with Dual Pixel CMOS AF, offering 5,655 manually selectable AF points covering nearly 100% of the frame. It excels in subject tracking and eye detection, providing fast and accurate focusing for both stills and video. This system is incredibly advanced and intuitive.
- 90d: Utilizes a more traditional 45-point all cross-type AF system (viewfinder) and Dual Pixel CMOS AF (live view) with 100% horizontal and 88% vertical coverage. While capable and reliable, it doesn’t quite match the sheer number of AF points or the advanced subject recognition of the EOS R.
- Winner: canon eos r
Video Capabilities
- Canon Eos R: Records 4K UHD video at up to 30fps with no crop, utilizing the full width of the full-frame sensor. It also offers 1080p at up to 60fps. The lack of a significant crop in 4K is a major advantage for videographers.
- 90d: Shoots 4K UHD video at up to 30fps, but with a 1.6x crop factor. It also offers 1080p at a faster 120fps for slow-motion playback. The crop factor can be a limitation for wide-angle video shots.
- Winner: canon eos r
Build Quality & Ergonomics
- Canon Eos R: Features a weather-sealed magnesium alloy body, offering a premium and durable feel. Its ergonomics are designed for comfortable handling, though some users find the control layout to be a departure from traditional DSLRs. The touch bar is a unique, albeit divisive, feature.
- 90d: Built with a robust polycarbonate exterior, still offering good weather sealing for its class. It retains the familiar DSLR ergonomics with a deep grip and well-placed physical controls, making it very comfortable for extended shooting sessions.
- Winner: canon eos r
Viewfinder & Screen
- Canon Eos R: Equipped with a high-resolution 3.69 million dot electronic viewfinder (EVF) and a fully articulating 3-inch touchscreen LCD. The EVF provides a clear and detailed view, while the vari-angle screen offers excellent shooting flexibility.
- 90d: Features a bright optical viewfinder (OVF) offering a 100% field of view and a vari-angle 3-inch touchscreen LCD. The OVF provides a direct, lag-free view of the scene, which some photographers prefer. The screen is also highly versatile.
- Winner: canon eos r
Lens Mount & Ecosystem
- Canon Eos R: Utilizes the newer RF mount, which is designed for higher performance and future lens development. While the RF lens lineup is growing rapidly and offers superb quality, it’s still a newer system with fewer native options compared to the established EF mount. Adapters for EF lenses are readily available.
- 90d: Uses the long-established EF/EF-S mount, offering access to a vast and diverse range of lenses, from budget-friendly to professional-grade. This extensive selection is a significant advantage for users who already own Canon EF glass or need specific lens types.
- Winner: 90d
Continuous Shooting Speed
- Canon Eos R: Achieves a continuous shooting speed of up to 8 frames per second (fps) with AF tracking. This is respectable for a full-frame mirrorless camera but might be a limiting factor for fast-action sports photography.
- 90d: Excels in this area with a blistering continuous shooting speed of up to 10 fps with full AF/AE tracking. This makes it a powerhouse for capturing fast-moving subjects like wildlife and sports.
- Winner: 90d
Battery Life
- Canon Eos R: Offers a CIPA-rated battery life of approximately 370 shots (using the EVF) or 350 shots (using the LCD). Mirrorless cameras generally consume more power due to the EVF/LCD.
- 90d: Boasts a significantly longer battery life, rated at approximately 1,320 shots (using the OVF) or 360 shots (using the LCD). The optical viewfinder’s lower power consumption contributes to its superior endurance.
- Winner: 90d
