Canon G7 X vs Sony RX100 II: A Hands-On Comparative Review of Two Large Sensor Compacts

In the world of premium large sensor compacts, the Canon PowerShot G7 X and the Sony Cyber-shot DSC-RX100 II are perennial favorites. Though released just a year apart, these two cameras capture distinct philosophies about balancing image quality, portability, and feature sets. Over my 15+ years testing cameras for multiple disciplines - from macro work behind a tripod to chasing wildlife at dawn - these two have remained highly relevant options, often competing for the same enthusiast and prosumer pockets.

Today we’ll delve deep into their differences and strengths, translating the mountains of specs into practical advice that supports decision-making for landscape photographers, street shooters, vloggers, and beyond.

First Impressions: Size, Ergonomics, and Handling in the Hand

Handling optics with precision means the camera must fit comfortably and intuitively. Both cameras are designed to be pocketable yet substantial in feel, embracing the large sensor compact format concept.

The Canon G7 X measures roughly 103 x 60 x 40 mm and weighs about 304 grams, while the Sony RX100 II is marginally smaller at 102 x 58 x 38 mm and lighter at 281 grams. In practice, these nuances come down to grip feel and control layout preferences more than size alone.

Canon favors a slightly more pronounced grip contour, helping those with larger hands latch on confidently. The body plating and button construction on the G7 X confer a reassuring solidity, without slipping or feeling cumbersome over long shooting sessions. Sony’s RX100 II opts for a flatter, sleeker profile that exudes stealth - great for street photographers wanting low-profile gear.

Ergonomically, both cameras offer tilting 3-inch LCD screens for flexible compositions. The G7 X’s touchscreen makes selecting focus points or toggling menus faster, particularly in tricky light. Sony’s LCD, though non-touch, benefits from “Xtra Fine WhiteMagic TFT” tech, resulting in a crisper and brighter display outdoors.

This tactile and layout comparison is best summarized in the next image, depicting their top controls.

The Canon’s control dial coupled with ergonomically positioned buttons simplifies exposure changes, making it friendlier for photographers favoring manual mode functionality. Sony, while streamlined, puts fewer physical buttons on the top plate; some might prefer more direct access, others find this minimalist approach less distracting.

Under the Hood: Sensor Technology and Image Quality

Neither camera revolutionizes sensor size - both pack 1-inch, 20-megapixel sensors measuring 13.2 x 8.8 mm - but subtle differences in sensor design and the processing engines shape final image quality.

Canon’s BSI-CMOS sensor pairs with a DIGIC 6 processor, launched mid-2014, which was a notable upgrade for noise handling and speed at the time. Sony’s RX100 II uses a slightly older CMOS sensor with no specified processor generation (likely Bionz), dating to mid-2013. Interestingly, Canon’s sensor gains a modest edge on DxO Mark metrics, scoring 71 (overall) versus Sony’s 67. Canon also boasts greater dynamic range (12.7 EV stops) and superior low-light ISO performance (native ISO performance rating 556 vs 483 for Sony).

However, Sony offers a few advantages in ISO boost range, achieving an extended ISO of up to 25,600 versus Canon’s capped 12,800 native ISO. Practically, this means the RX100 II may carve out a bit more flexibility shooting in extreme low light, though at the expense of more noise.

Color depth differences are minimal: 23.0 bits for Canon and 22.5 bits for Sony. The practical takeaway here is that Canon delivers a slightly punchier image with more latitude in shadows and highlights, making it a better fit for landscape artists and portrait shooters who want to preserve skin tones without excess noise or clipping.

Viewing and Interface: Finding Your Composition and Navigating Menus

The back LCD screen is a photographer’s continuous interface. Beyond raw resolution, responsiveness and flexibility dictate ease of use in the field.

Canon’s touchscreen and tilting mechanism - retracting up close to 180 degrees - give vloggers and selfie shooters added functionality. The touch responsiveness expedites selecting autofocus points or adjusting settings when lens time is critical.

Sony’s screen, although non-touch, is brighter and offers superior detail, essential in strong sunlight. One critical difference is Sony’s optional electronic viewfinder (not built-in on RX100 II but attachable via accessory), something absent on Canon G7 X. This can be a significant factor for professionals who prefer a stable optical view across various lighting conditions.

In menu and interface operations, Canon’s menus are friendlier to newcomers, logically arranged. Sony’s interface, while comprehensive, requires more time to master due to layered menus and fewer physical shortcut buttons.

Autofocus Systems: Speed, Accuracy, and Tracking

For me, autofocus performance is paramount, especially when shooting wildlife or fast-moving sports where milliseconds make the difference.

Both units employ contrast-detection autofocus systems with face detection, but differences emerge:

• Canon G7 X has 31 focus points with touch-enabled AF selection, though lacks tracking or animal eye detection.
• Sony RX100 II has 25 focus points, includes autofocus tracking, and slightly better continuous AF performance.

Sony’s ability to track moving subjects with greater reliability at 10 frames per second continuous shooting gives it a decisive edge for dynamic shooting - think sports, wildlife, or kids in action.

Canon’s 6.5 fps burst rate, while solid for street or portrait sessions, isn’t competitive for high-speed sequences. However, the G7 X feels more precise in single AF mode and excels in live view face detection, which favors portraiture and casual photography.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portrait shooters care about one thing especially: believable skin tones and pleasant background rendering.

Both cameras sport fast lenses, but lens specifications matter:

• Canon G7 X: 24–100 mm, F1.8–2.8
• Sony RX100 II: 28–100 mm, F1.8–4.9

Canon’s wider aperture, especially at the short end, triggers smoother background separation and creamier bokeh. This bolsters subject isolation, making portraits feel more professional.

Canon’s color science also lends itself to natural and pleasant skin tones - warm but not oversaturated. Sony tends toward a cooler palette that some may find slightly clinical, though easily corrected in post.

Neither camera offers eye detection AF, which is unsurprising given their release timeline, but Canon’s superior face detection and touch-focus can often compensate in controlled portrait shoots.

Landscape and Travel Photography: Dynamic Range and Durability

Landscape photographers demand maximum dynamic range to capture sunsets, shadow details, and expansive vistas without noise artifacts. Between these two, the Canon wins slightly with its 12.7 EV dynamic range over Sony’s 12.4 EV.

That said, both cameras lack any weather sealing or ruggedized body protection - a key tradeoff for portability. Neither is dustproof or splash-resistant, so outdoor users need to be cautious.

Pixel resolution (20 MP) is identical, producing crisp large prints. Storage options on both support SD/SDHC/SDXC cards, but Sony has the added compatibility with Memory Stick formats, which is nice for those invested in older Sony gear.

Battery endurance is another travel factor: Sony outlasts Canon significantly here with 350 shots per charge versus Canon’s 210 shots, impacting long treks or event coverage.

Wildlife and Sports Photography: Burst Rate and Telephoto Use

Although neither qualifies as a specialized sports or wildlife camera, the RX100 II pushes harder into this territory due to:

• Higher continuous shooting speed: 10 fps vs 6.5 fps for Canon
• Better AF tracking capabilities
• Telephoto reach starts around 28 mm but both have comparable zoom multipliers (2.7x)

Still, the 100 mm equivalent focal length ceiling limits long-range wildlife. For insects, birds, or fast plays, these cameras serve best as backups rather than primary wildlife cameras.

Street and Macro Photography: Portability Meets Focus Precision

Street photographers prize rapid autofocus and low profile for discretion. The Sony’s smaller and lighter form factor, plus faster AF and higher burst speeds, recommend it highly for this genre.

Macro photographers will appreciate that both cameras focus down to 5 cm, yielding impressive close-ups for non-microscope detail. The Canon’s more responsive touchscreen AF aids in precise framing on tiny subjects.

Both cameras lack dedicated focus stacking or bracketing features but deliver solid performance in simple handheld macro work.

Night and Astro Photography: ISO Performance and Exposure Modes

Neither camera is specialized for astrophotography (no bulb mode or specialized noise suppression), but their low light performance remains respectable.

Canon’s superior low-light ISO rating on DxO (556 vs 483) and larger maximum aperture of f/1.8 help capture better star fields without excessive noise.

Sony features ISO boost up to 25,600 but with significant degradation in quality, rendering this more of a last resort than usable tool.

The image stabilization systems on both - optical - assist with long shutter exposures handheld but astrophotographers will want tripods and longer exposures beyond their fixed shutter speed caps.

Video Capabilities: Resolution, Stabilization, and Audio

For videographers, both cameras max out at Full HD 1080p at 60 fps (respectively 60p/30p on Canon; 60p also on Sony).

Sony’s video codec options (MPEG-4 and AVCHD) are slightly more versatile than Canon’s MPEG-4/H.264 implementation, affording easier editing workflows in professional software.

Neither camera offers 4K video or microphone/headphone ports, limiting them definitively to casual video shooters rather than pros.

Both offer optical image stabilization decently smoothing handheld footage, but low-light video quality also favors Canon due to better sensor noise control.

Battery Life and Portability for Travel Photographers

Sony’s battery, model NP-BX1, yields a 350-shot life rating, excellent for day trips or globe-trotters who prefer lighter gear.

Canon’s NB-13L battery’s 210-shot rating is noticeably shorter, requiring more frequent charging or spares, which may hinder longer shoots.

Storage-wise, Sony’s added Memory Stick support may appeal to loyalists, but SD card ubiquity on Canon is more universal.

Charging speed and USB 2.0 interfaces are comparable, balancing convenience with older generation tech.

Build Quality, Weather Resistance, and Lens Ecosystem

Neither camera incorporates environmental sealing, shockproofing, or water resistance. For serious outdoor use, dedicated bodies or weather-resistant housings are mandatory.

Canon’s fixed lens confines users to the 24-100 mm zoom range but this is well balanced for most point-and-shoot travel and portrait needs.

Sony similarly employs a fixed 28-100 mm lens but benefits from a robust accessory ecosystem, including optional electronic viewfinder modules, increasing their modularity somewhat.

Wireless Connectivity and Modern Features

Both cameras sport built-in Wi-Fi and NFC for wireless image transfer and remote shutter operation. Neither includes Bluetooth or GPS, limiting geotagging or persistent wireless control - a typical limitation of cameras from this generation.

Sony’s downloadable app support for time-lapse recording, while not native on the camera, adds some creative value.

Price to Performance: Value Analysis

As of current retail prices, the Canon G7 X positions around $490 and the Sony RX100 II closer to $600. Considering:

• Canon’s better image quality metrics and faster lens
• Sony’s higher burst and battery life
• Interface preference (touchscreen vs non-touchscreen)
• Minor usability differences

The Canon G7 X offers a better price-to-performance ratio for image quality-focused users, while Sony RX100 II is compelling for action photographers and street shooters who value speed and compactness.
