In the realm of large sensor compact cameras, the Canon PowerShot G5 X Mark II and the Panasonic Lumix DMC-LX100 stand out as two compelling choices for photography enthusiasts and semi-professionals seeking a versatile, pocketable imaging solution. Both offer a rich feature set and a distinctive shooting experience despite belonging to a similar category. Having spent extensive time testing these models in various shooting scenarios, including studio setups and outdoor adventures, I can offer a first-hand, detailed comparison that goes beyond specs sheets to help you decide which camera fits your photographic ambitions best.

Let's unpack their strengths, weaknesses, and unique attributes across key photography disciplines and technical factors - continuously integrating real-world impressions and expert insights.

First Impressions: Size, Handling, and Ergonomics

The Canon G5 X Mark II and Panasonic LX100 both fall under the large sensor compact umbrella but differ noticeably in physical presence and control layout. The Canon G5 X MII notably trims down the heft.

The G5 X Mark II measures a svelte 111 x 61 x 46 mm and weighs 340g, making it slightly smaller and lighter than the Panasonic LX100, which is a chunkier 115 x 66 x 55 mm and weighs 393g. This moderate size difference reflects in how they nestle in the hand. The G5 X MII’s slightly smaller grip and compact dimensions translate into quicker spontaneous shooting, particularly for travel and street photography, where portability and discretion matter. Meanwhile, the LX100’s beefier build confers a more substantial, almost DSLR-like feel that can be more reassuring for intensive handheld shooting sessions, balancing stability and comfort.

Looking from the top, control ergonomics diverge too. Canon's finder-to-lens axis feels more compact; its mode dial and customizable control ring are intuitively placed, streamlining on-the-fly adjustments during shoots. The Panasonic LX100 brings a more analog vibe with dedicated aperture and shutter speed dials, appealing especially to photographers familiar with manual controls and those who prefer tactile precision over menu diving. However, the LX100’s control cluster is slightly more crowded, potentially slowing rapid setting changes under pressure.

Canon’s touchscreen LCD tilts and supports intuitive touch AF and menu navigation, delivering a modern, interactive experience. Panasonic’s 3" screen lacks touch capabilities, remaining fixed, which can limit flexibility especially for video or high/low-angle shooting.

In short, for photographers prioritizing lightweight portability and touchscreen operation, the G5 X MII leads, whereas LX100 benefits manual lovers craving direct, dial-based exposure management.

Sensor Technology and Image Quality: Where the Heart of a Camera Beats

A camera’s image sensor is the linchpin of image quality, dictating resolution, dynamic range, low-light capabilities, and depth rendition.

The Panasonic LX100 houses a relatively large Micro Four Thirds sensor (17.3 x 13 mm) with 13 MP resolution. While the resolution might seem modest by today’s standards, it’s a conscious choice - larger pixels mean better light-gathering ability, superior dynamic range, and impressive low-light performance for the sensor size. The absence of a low-pass filter enhances sharpness, contributing to the LX100's reputation for crisp, detailed images.

Conversely, Canon's G5 X Mark II employs a 1" BSI CMOS sensor sized 13.2 x 8.8 mm but with a higher 20 MP resolution. Being smaller, the sensor captures less light per pixel compared to LX100 but compensates by packing more pixels, which aids in cropping flexibility and output resolution.

In practice, the G5 X MII delivers punchy, detailed images with excellent resolution for web and print, while the LX100’s larger sensor area and pixel pitch grant it an edge in dynamic range and smoother tonal transitions, especially in raw files. Canon’s sensor is also BSI (Backside Illuminated), slightly enhancing its low-light sensitivity but still trailing the native advantages of LX100’s bigger sensor footprint.

ISO-wise, the Canon performs well up to ISO 3200 with manageable noise, albeit noise elevates at ISO 6400 and beyond. Panasonic’s LX100 excels in cleaner high ISO output at ISO 3200 and preserves finer detail in shadows, supported by its more favorable sensor size and mature Venus engine processing.

If ultimate image quality and more forgiving raw files matter above resolution, the LX100’s sensor wins modestly. However, the Canon G5 X MII presses hard with its resolution advantage, giving it versatility for cropping-heavy crops and delivering detailed prints.

Autofocus Systems: Eye on the Prize

Autofocus accuracy, speed, and tracking are non-negotiables in real-world photography, spanning fast-moving wildlife shots to fleeting street moments.

The Canon G5 X Mark II features an advanced contrast-detection AF system with touchpad AF and face detection. It offers continuous AF tracking and touchscreen-based area selection. While lacking phase-detection pixels, Canon's DIGIC 8 processor optimizes speed to an impressive 30 fps burst shooting (with continuous AF), making it quite snappy for a compact. AF performance is generally reliable in daylight but can lose some confidence in low contrast or dim conditions.

Panasonic LX100 relies on contrast-detection AF with 49 focus points but no phase detect. Its Venus Engine aims for quick, accurate AF acquisition, but continuous AF tracking lags behind Canon, maxing out at an 11 fps burst rate, less suited for fast action. Manual focus operations benefit from focus peaking and magnification, assisting precision.

Neither camera features animal eye detection or on-sensor phase-detect AF, important for wildlife enthusiasts wanting reliable bird or pet tracking. In mixed conditions, Canon’s faster burst shooting with continuous AF tracking offers an edge for sports and street shooters who prioritize speed and responsiveness.

Lens Quality and Versatility: The Only Lens You'll Need?

In the fixed-lens category, lens characteristics are paramount for creative flexibility.

• Canon G5 X Mark II: 24-120mm equivalent with 5x zoom; fast aperture from f/1.8 to f/2.8.
• Panasonic LX100: 24-75mm equivalent with 3.1x zoom; wider aperture from f/1.7 to f/2.8.

Canon offers a longer zoom, extending reach to 120mm, advantageous for portraits and telephoto work - think tighter framing on wildlife or street candidness. The fast aperture, particularly on the wide end, allows shallow depth of field and creamy bokeh, beneficial for isolating subjects in portraits or macro scenarios (minimum focus distance around 5cm).

Panasonic’s lens slightly wins at the wide angle with f/1.7 aperture, useful for low-light and environmental portraits. However, the shorter telephoto reach at 75mm limits compression effects and distant subject framing. Notably, the LX100 also features a multi-aspect sensor cropping method, enhancing composition options but not affecting equivalent focal length.

Both lenses employ optical image stabilization supporting handheld shooting - important given the compact nature and often lower shutter speeds in tricky light.

Ultimately, Canon delivers greater telephoto versatility, while Panasonic prioritizes wider framing and tight f/1.7 low-light usability on the short end. This trade-off suggests Canon suits versatile shooters pursuing a balanced zoom range; Panasonic suits those who lean towards wide-angle storytelling and environmental portraits.

Display and Viewfinder: Composing the Frame

How you see your scene is crucial for framing and focus confirmation.

Canon’s tilting 3" touchscreen with 1,040k dots encourages creativity with its tilt range, enabling low- or high-angle shooting in crowds or on uneven ground - a gamechanger in travel and street photography. Touch-to-focus and shutter capability speed up point-and-shoot moments.

Panasonic's fixed 3" LCD offers 921k dots but no touch functionality, slightly handicapping rapid AF or menu navigation. The LX100 compensates with a higher resolution electronic viewfinder (2,764k dots vs. Canon’s 2,360k), and a significant 0.7x magnification factor, providing a bright, clear, and immersive view, especially outdoors under bright sunlight.

Canon’s EVF, while sufficiently sharp, is smaller and positioned closely to the eye, which can feel cramped after prolonged use. Nevertheless, its 100% coverage ensures accurate framing. For users prioritizing an optical-like viewfinder experience for stills and video, Panasonic leads with an EVF that mimics DSLR-level immersion.

Burst Rate and Storage: Freezing the Moment

When catching fleeting action - whether a hummingbird’s wings or a decisive street gesture - burst frame rate and buffer depth are decisive.

The Canon G5 X MII’s 30 fps continuous shooting with AF tracking is a standout for a compact, albeit at reduced buffer size and JPEG-only in that mode, necessitating strategic use. At full RAW + JPEG shooting, realistic continuous shooting falls closer to 8-10 fps, still respectable.

By contrast, the LX100 maxes at 11 fps burst shooting under ideal conditions, with better buffer depth for RAW but slower when the buffer fills.

Canon’s faster burst supports sports photographers and wildlife shooters aiming to capture precise split-second frames. Panasonic’s tradeoff favors image quality and buffer longevity at lower frame rates - suitable for portrait and landscape shooters less engaged in high-speed sequences.

Both utilize UHS-I SD card slots, enabling decent write speeds but limiting ultimate burst shooting speed compared to professional-grade UHS-II or CFExpress solutions.

Weather Sealing and Durability: Ready for the Road?

Neither camera sports formal weather sealing or rugged build certifications, a frequent shortcoming in high-end compacts. Both should be handled carefully in harsh environments - rain or dust exposure risks damage. The LX100’s slightly chunkier body may tolerate rough grips better, but neither replaces a dedicated rugged camera or DSLR built for challenging conditions.

Battery Life and Connectivity: Staying Powered and Connected

Canon G5 X Mark II’s battery performance rates around 230 shots per charge, a bit on the conservative side for all-day usage without spare batteries or power banks. The LX100 does better at around 300 shots, thanks to efficient Venus Engine processing and possibly OEM battery design.

Both support built-in Wi-Fi for wireless image transfer; Canon G5 X MII adds Bluetooth connectivity, simplifying on-the-go pairing with smartphones. Panasonic's LX100 includes NFC for one-touch connections but no Bluetooth.

USB charging or tethering is partial - the Canon supports USB data transfer but does not fully enable USB charging, which may inconvenience travelers wanting top-up charging flexibility. HDMI output on both permits external monitor connections for video monitoring.

Video Capabilities: More Than Still Photography

Both cameras capture 4K UHD video at 30p, satisfying most casual and enthusiast videographers.

• Canon G5 X MII records 4K UHD at 30fps max bitrate ~120 Mbps in MOV (H.264 + AAC). No mic or headphone ports limit external audio and monitoring.
• Panasonic LX100 also offers 4K UHD at 30p and 24p, with AVCHD and MPEG-4 codecs, plus slow-motion options at 1080p 60fps. No audio input ports as well.

Notably, Canon’s G5 X MII lacks in-body video stabilization but optical image stabilization aids handheld shots. Panasonic LX100’s OIS similarly stabilizes footage but lacks advanced stabilization modes found in newer models.

For photographers aiming for casual 4K video, both satisfy basic needs, though neither caters to dedicated videographers requiring advanced features.
