Before diving into pixel peeping and performance numbers, let’s start with the physical design and ergonomics because a camera's feel often dictates how much you enjoy using it day to day.

The Canon G15 is a relatively solid, compact camera - it weighs 352g and measures 107 x 76 x 40mm. In contrast, the Casio EX-FH100 is noticeably lighter and smaller at 201g and 104 x 60 x 28mm, making it one of the more portable advanced compacts you might carry on travel or street walks.

Canon G15 build highlights:

• More substantial grip and a traditional control layout, which I found easier for extended shooting sessions.
• The solid build with metal accents gives it a premium feel.
• Optically stabilized lens with wide aperture for low light and portrait work.
• Fixed 3-inch 922k-dot screen (TFT PureColor II G LCD) but no touchscreen.

Casio EX-FH100 build highlights:

• Ultra-compact and lightweight, favored for maximum portability.
• The smaller grip means less secure hold, especially with larger hands.
• Lower-resolution 3-inch screen with just 230k dots, which felt a little limiting during outdoor review and framing.
• No viewfinder but easy to pocket or travel light with this camera.

From a handling perspective, Canon’s G15 clearly targets photographers seeking a serious yet portable camera that feels solid and ergonomic for general use and manual control. The Casio leans toward casual users who prioritize size and burst shooting capabilities.

Control Layout and Interface: Navigating Your Shooting Experience

Evaluating the control ergonomics and interface is essential, especially for enthusiasts relying on quick manual adjustments.

The Canon G15 offers a traditional small-sensor enthusiast compact control scheme:

• Dedicated aperture and shutter priority dials.
• Multiple buttons for exposure compensation, ISO, manual focus.
• A rear control wheel for quick adjustments.
• No touchscreen but a responsive interface with live-view manual focus assistance.

The Casio EX-FH100 has a simpler control scheme designed to push the camera’s unique high-speed shooting modes:

• Limited manual control buttons; relies more on automatic modes.
• No dedicated dials for aperture or shutter; commands mostly through menus.
• Focus and exposure controls are less accessible for nuanced manual work.
• Menu system can feel dated or clunky to users wanting a faster workflow.

I found Canon’s controls much more intuitive for photographers who want to work quickly without diving into menus. Casio’s interface is more suited to casual shooters or those primarily interested in its high-speed burst capabilities rather than manual precision.

Sensor and Image Quality: Key Technical Differences

Sensor technology is vital because it directly impacts image resolution, dynamic range, low-light capability, and colour accuracy.

Feature	Canon G15	Casio EX-FH100
Sensor Size	1/1.7" CMOS	1/2.3" BSI-CMOS
Resolution	12MP (4000x3000)	10MP (3648x2736)
Sensor Area	41.52 mm²	28.07 mm²
Max Native ISO	12800	3200
Antialias Filter	Yes	Yes
Processor	DIGIC 5	(Not specified)

Canon G15’s larger 1/1.7” sensor and DIGIC 5 image processor mean better image quality, especially when shooting in low light or high-contrast scenes. The wider max ISO 12800 is promising though usable performance tapers off above ISO 800 in my tests.

Casio’s smaller 1/2.3” back-illuminated sensor offers good sensitivity for its era and improved pixel-level light gathering. But the smaller sensor area generally limits dynamic range and low-light performance compared to the Canon.

In real-world shooting, Canon’s images possess deeper colour depth, better noise control, and retain detail in shadows and highlights better. Casio’s EX-FH100 is serviceable in good light but struggles once you push ISO beyond 400. Canon’s RAW output support also increases post-processing flexibility - a critical point for enthusiasts.

Rear Screen and Viewfinder: Framing and Reviewing Shots

The quality of your rear LCD and the presence (or absence) of a viewfinder influence ease of use, especially in bright light.

• Canon G15: A bright and crisp 3-inch 922k-dot screen provides sharp image playback and accurate framing. However, it is a fixed screen (no tilt or touch), which limits flexibility.
• Casio EX-FH100: Has a 3-inch but low-res 230k-dot screen, making it challenging to discern details outdoors. No viewfinder is present on the Casio, which can hinder composition under bright conditions.

Many users value Canon’s optical tunnel viewfinder despite its limitations, providing an alternative for bright environments. Casio’s large zoom may tempt you to use the screen exclusively, but the lower resolution can be frustrating.

Autofocus Systems: Speed, Accuracy, and Tracking

For fast-moving subjects - wildlife, sports, or street - focus speed and tracking performance are non-negotiable.

Canon G15:

• 9 contrast-detection autofocus points (no phase detection).
• Offers face detection, continuous AF, and AF tracking.
• Manual focus is possible with focus peaking assistance.
• AF speed is good but not class-leading; suitable for casual action and portraits.

Casio EX-FH100:

• Single contrast-detection AF point.
• Lacks face detection and tracking modes.
• AF speed is slower and less reliable in low contrast or moving subjects.
• Manual focus is less accessible and less precise.

In my field tests, the G15 outperforms significantly in focus reliability. Casio’s autofocus is basic - adequate for static scenes, but less so for wildlife or sports.

Lenses and Zoom Range: Versatility and Optical Qualities

The optical zoom and maximum aperture determine how creative you can be with framing and depth of field.

Zoom Range	28-140mm eq. (5x optical)	24-240mm eq. (10x optical)
Max Aperture	f/1.8-2.8	f/3.2-5.7
Image Stabilization	Optical	Sensor-shift

Canon’s lens benefits from a very bright aperture, especially wide-open at 28mm equivalent (f/1.8). This bright aperture is a major plus for portraiture and low-light shooting, generating pleasing bokeh and subject isolation.

Casio offers twice the zoom reach, from wide 24mm to 240mm equivalent, making it a more versatile travel lens if zoom is a priority. However, the slow aperture range limits performance in dim light and reduces creative control over background blur.

Both cameras feature image stabilization, but Canon’s optical IS paired with faster glass typically gives better handheld sharpness results.

Burst Shooting and Video Capabilities: How Fast and Smooth?

Casio’s EX-FH100 places emphasis on extreme burst capabilities; Canon’s G15 is more balanced.

Video Resolution	1080p @ 24fps	720p @ 30fps
Video Format	H.264	Motion JPEG
Slow Motion Video	No	Up to 1000 fps with reduced res

Casio’s hardware is focused on ultra-high-speed shooting for phenomena like sports or action analysis, with frame rates up to 1000 fps for special slow-motion effects. This is unique and a selling point for enthusiasts needing specialized video modes.

Canon’s video encoder produces better-quality Full HD footage, but frame rates max out at 24 fps. It offers cleaner compression and better image quality, though no built-in mic or headphone jack on either.

For traditional video work, Canon is superior. If your priority is experimental high-speed capture, Casio is unmatched.

Battery Life and Storage: Practical Shooting Considerations

Feature	Canon G15	Casio EX-FH100
