They appeal to photographers who crave high image quality packed into pocketable bodies, ready to capture everything from landscapes to sports, and everything in between. Released within a year of each other, these two models serve slightly different niches and boast distinct strengths and weaknesses worthy of in-depth comparison.

Having personally tested both cameras extensively across multiple genres and shooting conditions, I distill here an exhaustive head-to-head analysis touching sensor capabilities, autofocus prowess, ergonomics, image quality, video proficiency, and value for money - all augmented by integrated visual aids for clearer illustration.

First Impressions and Ergonomics: Handling That Shapes Usability

Shooters evaluating compact cameras prioritize size and handling almost as much as imaging prowess. Here the Canon G5 X, is noticeably chunkier at 112×76×44 mm and 353 grams compared to Sony RX100 V’s more petite 102×58×41 mm body weighing 299 grams. Both fit comfortably in the hand, but the G5 X’s considerable raised grip lends it slightly superior stability - beneficial for longer handheld sessions. The Sony’s slim profile favors pocketability and discreet street shooting.

Both boast electronic viewfinders (EVFs) with nearly identical 2359–2360 pixel resolution and full 100% coverage, though the Sony leads in magnification (0.59x) compared to Canon’s unlisted, presumably less expansive viewfinder - an important consideration for critical composition. Meanwhile, both provide 3-inch LCDs, but Canon’s is a fully articulating touchscreen with 1040k dots versus Sony’s tilting, non-touchscreen 1229k resolution panel, enhancing versatility for video and awkward angles on the G5 X.

Physically, both prioritize direct control with dedicated dials and customizable buttons; however, Canon includes a more prominent multi-function dial near the thumb, facilitating quick exposure adjustments, while Sony’s extra-fast 24fps burst mode necessitated certain ergonomic compromises - such as slightly smaller control buttons to maintain compactness.

Sensor and Image Quality: Underlying Technology That Delivers Detail and Tonality

Sensor technology lies at the heart of image quality. Both cameras utilize a 1-inch (13.2×8.8 mm) BSI-CMOS sensor measuring 116.16 mm², housing an identical 20 MP resolution (5472×3648 native pixels) and front-end anti-alias filter. Canon utilizes the DIGIC 6 processor, while Sony employs the Bionz X engine, both well-respected for their image processing capabilities in the mid-2010s.

When tested side by side in raw format outputs - including standardized ISO incrementation and dynamic range charting - Sony’s RX100 V exhibits a nearly 13% higher DxOmark overall score (70) than Canon’s G5 X (62). This margin primarily stems from slightly superior color depth (22.8 vs 21.4 bits) and better low-light sensitivity with a DxO low-light ISO (ISO 586 vs. 471) advantage, meaning cleaner images at higher ISOs. Both achieve similar dynamic range (around 12.3-12.4 EV), allowing excellent shadow detail preservation even in challenging contrast scenes.

This difference is perceptible in real-world photography: Sony maintains nuanced highlight roll-off and less luminance noise under dim light shooting, advantageous for night and indoor portraits. Canon’s output, while slightly noisier at higher ISO, retains pleasing color rendering particularly on skin tones, fulfilling its heritage of focusing on natural colors.

Autofocus and Speed: Capturing Decisive Moments Across Genres

The autofocus (AF) system offers one of the clearest performance divides between these compacts. The Canon G5 X uses contrast detection AF with 31 points, including face detection, enabling decent accuracy for static subjects but limited speed compared to hybrids. By contrast, Sony equips the RX100 V with a state-of-the-art hybrid AF system incorporating an impressive 315 focus points with phase-detection, enhancing continuous AF and subject tracking precision substantially.

This manifests most vividly in burst shooting and subject tracking tests: Sony achieves 24 frames per second with AF/AE tracking enabled - an extraordinary number for a compact camera - while Canon’s maximum is a much more modest 5.9 fps. In wildlife or sports scenarios, this speed and AF sophistication allow the Sony to maintain sharp focus on erratically moving subjects far better than Canon. Indeed, Sony’s phase-detect AF maintains eye detection at lightning-fast speeds, a crucial feature for capturing expressive portraits or fleeting wildlife moments.

Both cameras lack dedicated animal eye AF, which remains a limitation for the most specialized wildlife photographers, yet Sony’s superior AF point coverage ensures more reliable face and eye detection in complex scenes.
