Canon EOS R100 Mirrorless Camera w/RF-S 18-45mm f/4.5-6.3 STM Lens + Wide Angle & Telephoto Lenses + 64GB Memory + 3pc Filter Kit + Case + Flash + Tripod vs Sony Alpha a6400 Mirrorless Camera: Compact APS-C Interchangeable Lens Digital Camera with Real-Time Eye Auto Focus, 4K Video, Flip Screen & 16-50mm Lens - E Mount Compatible - ILCE-6400L/B, Black

Price and Value: Canon EOS R100 Bundle Offers Significant Savings

The Canon EOS R100 bundle is about 28% cheaper than the Sony Alpha a6400, priced at $599.00 compared to $835.90. This $236.90 difference represents substantial savings for buyers seeking a complete photography setup. The Canon package includes not just the camera and lens but also a 64GB memory card, three filters, a flash, tripod, wide-angle and telephoto attachments, a camera bag, and numerous accessories. In contrast, the Sony a6400 comes with only the body, lens, battery, charger, strap, and basic accessories. For users prioritizing immediate usability and value, the Canon’s all-inclusive offering delivers far more for less money.

Camera Body and Sensor: Canon Leads in Resolution and Processing Power

The Canon EOS R100 features a 24.2MP APS-C CMOS sensor paired with the DIGIC 8 image processor, which supports high-speed performance and improved image quality. While the Sony Alpha a6400 uses a 20.1MP stacked back-illuminated sensor, the Canon’s higher resolution and dedicated processor give it an edge in detail capture and processing efficiency. The Canon’s sensor is specifically designed for fast autofocus and video performance, while the Sony’s stacked design enhances readout speed—though this advantage isn’t reflected in the provided specs. The Canon’s sensor resolution exceeds the Sony’s by 4.1 megapixels, making it better suited for high-resolution stills and detailed cropping.

Autofocus and Performance: Real-Time Eye AF Gives Sony an Edge

Sony’s Alpha a6400 boasts real-time eye autofocus, a feature absent from the Canon EOS R100’s listed capabilities. This technology enables precise tracking of human and animal eyes during both photo and video capture, significantly improving accuracy in portrait and action shots. The Sony system uses 425 phase-detection and 425 contrast-detection autofocus points covering 84% of the sensor, providing extensive coverage. The Canon offers Dual Pixel CMOS AF with 143 AF zones, which is effective but less comprehensive. For photographers focused on dynamic subjects or vlogging, the Sony’s advanced eye-tracking system provides a measurable advantage in reliability and precision.

Video Capabilities: Canon Supports 4K with Crop, Sony Offers Uncompressed Options

Both cameras support 4K video recording, but their implementations differ. The Canon EOS R100 records 4K 24p with a crop, meaning the image is slightly zoomed in due to sensor limitations. The Sony Alpha a6400, however, captures 4K video without a crop, preserving full-frame framing. Additionally, the Sony allows for time-lapse movies and slow/fast-motion videos without post-processing, a feature not mentioned for the Canon. While the Canon’s 4K output is usable, the Sony’s lack of crop and built-in editing functions make it superior for videographers needing maximum flexibility and cinematic quality directly from the camera.

Lens and Accessories: Canon Delivers a Complete Kit, Sony Sells Barebones

The Canon EOS R100 bundle includes the RF-S 18-45mm f/4.5-6.3 STM lens along with a wide-angle macro attachment, telephoto attachment, UV, CPL, and fluorescent filters, plus a flash, tripod, memory card, and maintenance kit. This makes it ready to use out of the box. The Sony Alpha a6400 comes with a 16-50mm lens (not specified as f/1.8-2.8), but no additional lenses, filters, or accessories beyond a battery, charger, strap, and cable. The Canon’s inclusion of multiple lenses and tools adds significant practical value, especially for beginners or those avoiding extra purchases. The Sony’s minimal kit requires users to invest further to achieve similar functionality.

Display and Viewfinder: Canon Offers Higher-Resolution OLED EVF

The Canon EOS R100 features a 2.36m-dot OLED electronic viewfinder (EVF), which provides sharper and more detailed viewing than the Sony Alpha a6400’s standard viewfinder. The Canon’s 3-inch LCD screen has a 1.04m-dot resolution, ensuring clear image preview and accurate color representation. The Sony’s tiltable LCD screen is useful for vlogging and low-angle shots, but its resolution isn’t specified. The Canon’s higher-resolution EVF gives photographers better control over composition and focus, particularly in bright conditions where screens can be hard to see. This upgrade enhances overall shooting experience and precision.

Which should you buy?

Choose the Canon EOS R100 if you want a complete, ready-to-use photography system at a lower price point. It’s $236.90 cheaper than the Sony Alpha a6400 and includes a 64GB memory card, three filters, a flash, tripod, lens attachments, and maintenance tools—making it ideal for beginners or hobbyists who value convenience and immediate usability. However, if you prioritize advanced autofocus like real-time eye tracking, uncropped 4K video, and greater flexibility in video editing, the Sony Alpha a6400 is worth the extra cost despite its barebones kit. Ultimately, the Canon wins on value and completeness; the Sony wins on professional-grade video and autofocus performance.
