Canon G9 X II vs Casio EX-100: A Hands-On Comparison for Serious Enthusiasts

When I first sat down to compare the Canon PowerShot G9 X Mark II and the Casio Exilim EX-100, I knew we were dealing with two interesting compact cameras aimed at users who want more than just a point-and-shoot experience - but from rather different angles. The Canon focuses on offering excellent image quality from a larger sensor and a sleek pocketable body, whereas the Casio trades sensor size for a longer zoom and a more versatile lens.

After extensively testing both, I’m ready to share how they stack up through the lens of practical photography disciplines, real-world performance, and pure technical muscle. Whether you’re a portrait shooter, travel buff, or weekend wildlife hunter, my goal is for you to leave here informed, confident, and maybe a little inspired.

Setting the Stage: Form Factor, Build, and Handling

First impressions matter, and in compact cameras, size and ergonomics can make or break your shooting experience. Here’s a quick look at the physical aspects that you’ll deal with daily:

Both cameras wear their compactness proudly, but the Canon G9 X II is the more petite sibling. Measuring just 98 x 58 x 31 mm and weighing 206 grams, it slips neatly into a jacket pocket or purse - perfect if size and discretion are your priorities. The Casio EX-100 is a chunkier 119 x 67 x 50 mm at 389 grams mainly due to its more complex zoom mechanism and battery size, which some will appreciate as a more substantial grip.

From my hands-on time, the Canon G9 X II feels intuitively designed for quick one-handed operation. Controls are accessible and well-placed, although the lack of a viewfinder can feel odd if you’re used to framing through one. The Casio’s tilting screen and the longer zoom lens make it more versatile for creative compositions but slightly less pocket-friendly.

Notice on the top views how the Canon keeps things simple and clean, with a traditional mode dial, zoom lever, and shutter placement aimed at photographers who want to jump into manual modes quickly. The Casio sports a more recessed shutter and zoom ring combination, which sometimes benefits stability but feels somewhat dated in an era of faster controls.

If portability with decent handling is your aim, the Canon wins by a hair. But for zoom versatility and tilt screen flair, Casio deserves a look.

Sensor & Image Quality: Big Sensor vs. Superzoom Sensor

The sensor is the heart of any camera, dictating much of the image quality and dynamic range you can extract. Here’s where the Canon G9 X II excels:

A 1-inch BSI-CMOS sensor (13.2 x 8.8 mm) with a 20MP resolution gives Canon a considerable edge in pixel-level detail, noise handling, and color depth. The Casio EX-100’s smaller 1/1.7-inch sensor (7.44 x 5.58 mm) delivers 12MP, pushing it into superzoom compact territory but sacrificing the finer image quality nuances Canon offers.

In real-world tests, the Canon’s sensor produces cleaner images at higher ISO settings - even up to ISO 3200 is usable with modest noise, thanks to the DIGIC 7 processor’s excellent noise reduction algorithms. Color depth clocks in at 21.9 bits on DxOMark metrics, reflecting subtle tonal transitions, especially important for skin tones in portraits and complex landscapes.

The Casio’s smaller sensor understandably struggles more with noise beyond ISO 400, and while the native ISO tops out at 12800 (boosted to 25600), usable images above 800 become questionable.

Sharpness-wise, the Canon’s anti-aliasing filter balances moiré control with crisp detail retention, while Casio’s filter is similar but hampered by lower pixel count and sensor size.

For pixel peepers and those thirsting for dynamic range (notably 12.5 EV on Canon), the G9 X II offers clear advantages. Casio focuses more on focal range versatility than pure image sensor performance.

Autofocus and Focusing Experience

Autofocus systems on compact cameras are often overlooked but hugely impact your ability to nail shots in real time.

The Canon G9 X II employs a contrast-detection AF system with touch-to-focus capability on its 3-inch touchscreen, offering single, continuous, and tracking modes. While it lacks phase-detection sensors, in daylight and typical scenes the AF is snappy and reliable. Face detection works well but animal eye AF isn’t supported, so wildlife portraiture can demand manual focus or patience.

Casio’s AF system, featuring 25 contrast-detection focus points, helps a bit with zone focusing and tracking moving subjects. It offers continuous AF but no touchscreen, so manually shifting focus requires buttons or dials, which slows shooting speed a bit compared to Canon’s tap-to-focus flow.

Below the autofocus scores, Canon’s touch interface makes manual focus tweaks feel natural. Casio’s more traditional approach may suit shooters accustomed to physical controls, but the lack of touch can frustrate those used to smartphone-like control.

LCD and Viewfinder Usability

Neither camera supports an electronic viewfinder, but their rear screens are quite different in both size and quality.

The Canon’s 3-inch fixed touchscreen provides a very sharp 1,040k-dot resolution, with excellent brightness and color accuracy. Touch responsiveness is smooth, and navigating menus or setting focus points is intuitive after just a few shots.

In contrast, Casio’s 3.5-inch "Super Clear" LCD with a 922k-dot resolution is larger and tilting. This tilt is a bonus for shooting from unusual angles or low positions - a creative advantage you won’t find on the Canon. However, the lack of touch means you have to fish through menus with buttons, which can slow you down and feel a bit old-fashioned.

If you value touch responsiveness and clarity for quick settings, Canon is the clear winner here. But the Casio’s tilt screen is compelling for certain creative workflows.

Performance Across Photography Genres

Portrait Photography

Canon's larger sensor combined with the fast f/2 aperture at wide end creates beautiful shallow depth-of-field effects that are crucial when shooting portraits. The 3x zoom (28–84mm equivalent) covers a comfortable portrait focal length range. The colors are naturally rendered with skin tones looking pleasing and accurate, especially with the DIGIC 7 processor aiding color science.

The Casio’s longer zoom (28–300mm equivalent) can reach flattering longer portrait perspectives, but the smaller sensor and f/2.8 aperture mean less background blur and weaker low-light performance. Its face detection AF is solid but struggles to gently render skin tones as well as Canon’s sensor and processing combo. I’d put Casio as a secondary option for portraits - fine for casual shots but lacking the nuanced bokeh and color fidelity you get from Canon.

Landscape Photography

The G9 X II's larger sensor paired with its 20MP resolution delivers images rich in detail and excellent dynamic range (12.5 stops when RAW shooting). This allows retention of highlight and shadow details especially when shooting sunrise, sunset, or complex scenes.

Casio’s smaller sensor reduces dynamic range and resolution, but the superzoom’s 28-300mm range allows framing distant landscape features that Canon can’t capture without additional lenses.

Neither camera is weather-sealed, so outdoor shooters should care for them in wet or dusty conditions. For pure resolution and tonal quality, Canon’s G9 X II is your pick. For telephoto landscape shots, Casio’s EX-100 lens offers versatility - but with image quality compromises.

Wildlife Photography

Telephoto reach is king, and here Casio flexes its muscles. The EX-100’s 10.7x zoom from 28mm to 300mm equivalent allows framing distant wildlife where the Canon’s 3x zoom falls short. However, the smaller sensor and limited AF functions (contrast only) mean focusing on fast-moving animals can be slow or inaccurate, especially in low light.

Canon counters with cleaner high ISO performance, aiding in faster shutter speeds, but the zoom reach is less practical for serious wildlife shooting. Also, neither camera offers burst rates or autofocus systems optimized for fast tracking of erratic wildlife movement - the Casio does offer an impressive 30fps continuous shooting mode though with likely reduced AF accuracy, while the Canon manages a decent 8.2fps but exercises more AF intelligence.

Wildlife enthusiasts will find Casio’s zoom tempting, but image quality and tracking limits mean it is best as a casual backup rather than a dedicated wildlife camera.

Sports Photography

Neither camera caters directly to sports professionals, but I tested their tracking and frame rates.

Casio’s 30fps burst mode stands out and, combined with 25 AF points, gives a snappier experience catching fast action – though focus tracking can still lag with complex subjects or low contrast environments.

Canon’s 8.2fps is respectable, with better noise control at higher ISO and commendable image quality. Yet the limited zoom and no phase-detect AF can frustrate capturing unpredictable action.

For casual sports, especially outdoors with good light, Casio has an edge in catching fleeting moments. Serious sports shooters should look elsewhere, but these cams can manage fun family events or street sports with some patience.

Street Photography

The G9 X II’s small size, discrete design, quiet shutter, and touchscreen AF make it superb for street photographers valuing inconspicuous presence. The lens offers a versatile 28-84mm range covering most street scenes, including environmental portraits or candid close-ups.

The EX-100 is bulkier and zoomed longer, less ideal for stealthy street work. However, its super clear, tilting screen aids shooting from unconventional angles in crowded situations.

Low light favors Canon’s sensor and image stabilization, which reduces motion blur discreetly - a must on the street after dusk.

Overall for street work, Canon G9 X II wins hands-down.

Macro Photography

Both cameras focus as close as 5cm, but the Canon’s stabilizer and larger sensor enable sharper, cleaner macro shots with better color rendition.

Casio’s longer zoom helps if you want to shoot small critters at a slight distance preventing disturbance. However, sensor noise at macro apertures and less precise autofocus can hamper macro results.

For serious macro exploration, Canon again nudges ahead.

Night and Astrophotography

Canon’s 1-inch sensor combined with the DIGIC 7 processor and maximum native ISO of 12800 makes it surprisingly adept at night scenes and limited astrophotography. Exposure modes and manual controls are straightforward, plus optical stabilization helps reduce hand shake during longer exposures.

Casio offers similar ISO range but image noise crops up sooner, and no special astrophotography modes or long exposure aids put it at a disadvantage.

Serious night photographers will appreciate what Canon delivers at this price point.

Video Capabilities

Both cameras max out at Full HD 1080p video - Canon affords 60fps (smooth motion) with H.264 encoding and AAC audio, while Casio tops out at 1920x1080, frame rates less specified but presumably 30fps max.

Neither camera has microphone or headphone jacks. Canon's video autofocus is decent with continuous AF modes and touch targeting.

Casio’s stabilization system is sensor-shift and effective but less sophisticated than Canon’s optical stabilization.

For casual video, Canon delivers the slightly better package.

Travel Photography

Travel photographers will relish Canon’s pocket-friendliness, excellent image quality, and dependable battery life (about 235 shots per charge) for a day out. Wireless connectivity (Wi-Fi, Bluetooth, and NFC) makes quickly sharing photos on the go effortless.

Casio’s longer zoom reduces lens changes or compromises - it achieves almost double the battery life at 390 shots, a big plus on extended trips. However, lack of Bluetooth and smaller screen responsiveness are drawbacks.

Choosing between more portability (Canon) or zoom versatility and battery longevity (Casio) comes down to your trip profile.

Professional Workflow

Neither camera is designed as a professional rig, but the Canon G9 X II’s support for RAW files, “DIGIC 7” processing, and better color depth integrate well with standard editing workflows.

Casio also offers RAW but fewer controls and less stable post-processing benefit from smaller sensor data.

Canon’s USB 2.0 and HDMI ports stand on par with Casio’s; wireless features favor Canon allowing remote shooting and easier tethering.

Neither offers weather sealing or rugged build for demanding professional fieldwork.

Build Quality and Weather Resistance

Both cameras share a compact but unsealed design. Expect them to perform reliably in normal conditions but handle moisture, dust, or shocks with care.

Canon’s lighter magnesium alloy body feels premium and rigid; Casio’s extra weight comes from solid construction but is mostly plastic. Neither is freezeproof or crushproof.

If weather sealing is a priority - you’ll need to look to other options.

Battery Life and Storage

Canon’s 235-shot battery life is average but sufficient for casual daily shooting; the Casio’s 390-shot endurance impresses given its compact size.

Both support SD/SDHC/SDXC cards with single slots.

For longer outings or events, Casio edges out in endurance, though carrying spares is wise either way.

Connectivity and Wireless Features

Canon G9 X II surprisingly includes Wi-Fi, Bluetooth, and NFC, enabling seamless pairing with smartphones for instant sharing or remote capture.

Casio sticks with just Wi-Fi, no Bluetooth or NFC, limiting quick connections.

Wireless flexibility is thus a clear win for Canon.

Price-to-Performance Considerations

The Canon delivers more bang for most photography styles if sheer image quality, ease of use, and compactness are your priorities. The Casio appeals if zoom versatility and longer battery life are non-negotiable.
