In this detailed comparison, I’ll walk you through the essential strengths and weaknesses of each model, drawn from exhaustive real-world testing paired with in-depth technical analysis. My goal is to help you make an informed decision based on practical experience and expert insights rather than marketing hype.

Let’s dive in.

Getting to Know the Cameras Up Close: Design and Ergonomics

When I first picked up the Canon R8 and Panasonic S5, their SLR-inspired mirrorless bodies felt distinct in hand. While both cameras embrace the classic DSLR silhouette, their physical dimensions and weight differ substantially.

The Canon R8 is remarkably lightweight at just 461g with compact dimensions (133×86×70mm), making it one of the smallest full-frame mirrorless cameras on the market. Holding it felt like a breath of fresh air after lugging heavier setups - ideal for long shooting days or travel without sacrificing sensor size. The grip is modest but quite comfortable, especially for smaller-to-medium hands. Controls are well-placed, though the body’s compactness limits the number of customizable buttons slightly.

In contrast, the Panasonic S5 is notably more substantial at 714g and measuring 133×97×82mm, with a sculpted grip that inspired confidence for extended handheld shooting. It feels robust without being cumbersome. The extra heft contributes to better balance, especially when paired with longer lenses – a point worth considering for wildlife or sports photographers who often rely on telephotos.

Keen observers will appreciate subtle layout differences apparent from above:

The Canon favors simplicity, channeling all-important dials and buttons efficiently with a somewhat minimalist approach on top, including a shutter speed dial and mode dial. Panasonic’s S5 adds a dedicated ISO dial atop the camera alongside aperture and shutter speed adjustment wheels - catering nicely to seasoned photographers who value tactile, direct control over exposure settings.

In daily use, the S5's longer battery life (440 shots vs. Canon’s 290) and dual SD-card slots significantly contribute to reliability during longer shoots, an advantage for working professionals. The R8’s single UHS-II slot is still fast and dependable but requires more frequent media swaps or external backup strategies.

Sensor Technology and Image Quality - Keeping Image Quality Front and Center

Both cameras mill around a 24-megapixel full-frame sensor, yet their designs and performance nuances reveal noticeable differences that matter in the field.

The Canon R8 utilizes a CMOS sensor of 36x24mm with a conventional anti-aliasing filter, balancing sharpness with moiré artifact control. Canon’s sensor architecture and image processing pipeline deliver excellent color depth (24.5 bits), dynamic range (~14.5 stops), and solid low-light ISO performance rated at 3295 ISO according to DxOMark. I personally found the skin tones to be impressively natural and warmth inviting in portrait sessions, an important aspect when photographing people that’s often subjective but critical in my experience.

Panasonic’s S5 sensor of 35.6x23.8mm lacks an anti-aliasing filter, resulting in very crisp images with exceptionally fine detail - great for landscape and macro shooters who prioritize resolution fidelity. Panasonic pairs this with versatility across dynamic range and excellent noise control up to ISO 51200 (native) and extendable to 204800. While not formally tested by DxOMark, my hands-on comparison revealed Panasonic’s images retain remarkable shadow detail in tricky lighting conditions, making it a reliable starry-night or low-light landscape tool.

Examining actual samples illustrated these traits beautifully:

The Panasonic, meanwhile, excelled at texture-rich subjects like foliage and rock-detail in landscapes, highlighting how each system’s sensor and lens ecosystem align with different creative priorities.

Autofocus Systems Put to the Test

Autofocus can make or break a camera’s real-world performance, especially in fast-moving or dynamic shooting conditions.

The Canon EOS R8 features an impressive Dual Pixel CMOS AF II system with 1053 selectable points, combining phase-detection and contrast-detection for fluid, accurate focusing. Its standout feature is comprehensive eye and face detection that extends to animals - a relatively recent Canon innovation I’ve tested extensively. When tracking wildlife or pets, the R8 maintained lock with very few focus misses, even in rapid movement or complex backgrounds.

Panasonic’s S5 employs a contrast-based DFD (Depth From Defocus) autofocus system with 225 focus points distributed strategically. While refined for smooth live-view focusing, it can lag behind Canon’s hybrid system in certain fast-tracking scenarios. I found that during sporting events or birds-in-flight, the S5 occasionally struggled with erratic focus shifts, especially in lower light. However, it compensates with excellent manual focus aids, focus peaking, and focus bracketing/stacking - a boon for macro and landscape photographers who prefer deliberate control.

If autofocus speed and reliability in action-sports, wildlife, or portraiture with unpredictable subjects top your priority list, Canon’s sophisticated AF architecture currently holds an edge in my experience.

Handling and Intuitive Controls for Real-World Shooting

Beyond technical specs, a camera’s handling profoundly affects how comfortably and quickly you can capture moments.

Both cameras sport 3.0-inch fully articulated touchscreens, but the Panasonic S5 boasts a higher-resolution 1.84M-dot panel compared to the Canon’s 1.62M dots. I found the Panasonic’s screen delivered crisper previews with better visibility in bright daylight, enhancing composition and menu navigation on the fly.

Both manufacturers provide intuitive touchscreen-based menu navigation, though Canon’s interface felt slightly more streamlined and beginner-friendly, with clearly categorized controls and helpful explanations - a plus for those transitioning from DSLR to mirrorless.

While neither camera offers built-in image stabilization in the R8, the Panasonic integrates 5-axis in-body image stabilization (IBIS) that proved invaluable in handheld shooting, particularly for low-light interiors, night scenes, and telephoto work. On several occasions, I captured sharp images at shutter speeds two stops slower than typical handheld limits, without fatigue-inducing tripod setups.

Exploring the Lens Ecosystems

Lens availability and compatibility are crucial for long-term satisfaction.

Canon’s R8 inherits the RF lens mount, which, despite being relatively new, already offers an expanding portfolio of 37 native lenses, including outstanding fast primes and versatile zooms. Thanks to Canon’s optical engineering, I appreciated the exceptional sharpness and background separation when using RF lenses, particularly in portraiture and macro shots.

Panasonic’s S5 utilizes the Leica L mount, shared with Sigma and Leica themselves. This results in a growing but still limited lineup of roughly 31 native lenses. However, this system benefits notably from the compatibility with Panasonic’s excellent line of Lumix S-series lenses optimized for sharpness and optical image stabilization - effectively complementing the camera’s IBIS.

If lens availability and investment continuity matter to you, Canon’s RF mount currently offers broader selection and innovation, while Panasonic’s system promises quality with some niche and manual-focus gems favored by video and hybrid shooters.
