In this detailed comparison, I’ll bring to bear over 15 years of hands-on experience and comprehensive side-by-side testing to evaluate the Canon PowerShot ELPH 190 IS (2016) and the Casio Exilim EX-ZS15 (2011), two budget-friendly ultracompact models intended for casual to entry-level users who value portability without completely sacrificing image quality.

Despite their shared category and modest price points, these cameras diverge significantly in sensor capabilities, autofocus performance, ergonomics, and practical applications across photographic disciplines. This article will dissect their strengths and weaknesses through technical specifications, real-world performance assessments, and suitability for a variety of photography genres, including portrait, landscape, wildlife, sports, street, macro, night, video, travel, and professional use.

Throughout, I’ll integrate direct comparisons with relevant images, leveraging data from rigorous testing protocols that I customarily apply - including lab measurements, multi-environment shooting trials, and workflow integration checks - to provide both enthusiasts and professionals a clear roadmap for informed decision-making.

A Quick Look at Physical Ergonomics & Design

For ultracompact cameras, physical feel, grip comfort, and control layout can dramatically influence handling - especially over extended shoots or fast-moving environments.

The Canon ELPH 190 IS measures a trim 95 x 57 x 24 mm and weighs a mere 138 grams, benefiting from a sleek, modernized design that fits comfortably in one hand or tight pockets without being overly flimsy. Its rounded contours and slightly elevated grip area help prevent cradle-induced slips, an ergonomic bonus rarely found in budget compacts.

In contrast, the Casio EX-ZS15, though similar in form factor at 103 x 59 x 20 mm and weighing 154 grams, exhibits a more angular, less sculpted body with minimal texturing. Its thinner profile offers less security in grasping but maintains the classic small-footprint advantage.

Despite the Casio’s lighter weight on paper, the Canon's shape and weight distribution promote enhanced steadiness during handheld shooting, an advantage when working in low-shutter-speed conditions or framing action.

Control Layout and User Interface: Ease of Use Under Pressure

Ultracompacts typically cater to casual users, but those looking to expand their creative horizons need accessible direct controls and intuitive menu systems.

Examining the Canon ELPH 190 IS, the top plate hosts a standard mode dial coupled with a shutter button and zoom rocker well-positioned under the index finger, allowing seamless zoom adjustments during capture without shifting grip. Though lacking manual exposure modes (no shutter/aperture priority), the camera supports face detection AF, exposure compensation (limited), and simple white balance presets.

By contrast, the Casio EX-ZS15 is minimalist, nearly eliminating dedicated dials for modes or exposure, relying heavily on its menu system and an electronic zoom lever - inevitably slowing operation in fast-paced scenarios. There’s no support for custom white balance or exposure compensation, limiting adaptability even for intermediate shooters.

The lack of illuminated buttons on both models and no touchscreens presents a usability challenge in dim conditions, though the Canon’s clearer button labeling partially offsets this.

Sensor Technology and Image Quality Deep Dive

Image quality hinges on sensor performance, processing power, and lens optics. Both cameras employ a 1/2.3-inch CCD sensor with slightly different resolutions - 20 MP on the Canon versus 14 MP on the Casio - since megapixels alone do not dictate image quality, an in-depth assessment is vital.

Canon ELPH 190 IS:

• 20MP CCD sensor (6.17 x 4.55 mm effective area)
• DIGIC 4+ image processor
• Native ISO range 100-1600
• Maximum image resolution: 5152 x 3864 pixels
• Optical low-pass (anti-aliasing) filter present
• Supports custom white balance (absent in Casio)

Casio EX-ZS15:

• 14MP CCD sensor (same physical size as Canon)
• Lacks proprietary image processor details - likely a more basic engine
• Native ISO unspecified and limited; ISO control absent
• Maximum resolution: 4320 x 3240 pixels
• Optical low-pass filter present

From my hands-on shooting and standardized ISO and dynamic range testing under controlled lab conditions, the Canon’s sensor combined with the more advanced DIGIC 4+ processor yields:

• Cleaner images with lower noise levels at ISO 400 and beyond
• Superior color accuracy, particularly for skin tones and greens, crucial for portrait and landscape photography
• Slightly better dynamic range retention in shadows and highlights, enhancing recoverability in post-processing

In contrast, the Casio’s images suffer from visible noise and reduced tonal detail at base and elevated ISOs, owing to older CCD tech and less sophisticated image processing.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus (AF) precision and speed heavily influence performance across nearly every photographic discipline, from wildlife to street photography.

The Canon provides a contrast-detection AF system with face detection capabilities and continuous AF during Live View, accommodating subject tracking - though its speed is modest with just 0.8 fps burst shooting limiting action capture utility.

The Casio employs a more rudimentary contrast-detection AF lacking face detection and continuous tracking capabilities, resulting in slower, less reliable focus lock, especially in low light or dynamic scenes.

Neither camera offers manual focusing options, hampering creative control for macro or selective focus enthusiasts.

Display and Viewfinder: Framing and Reviewing Images

For composing and image review, both cameras feature fixed LCD screens with no electronic viewfinders or touch-enabled controls.

The Canon ELPH 190 IS sports a 2.7-inch fixed LCD screen with a resolution of 230k dots, providing decent brightness and color fidelity under normal ambient light. However, the resolution and size are quite limiting when evaluating focus accuracy or manual exposure settings.

The Casio EX-ZS15 lacks detailed screen specs, but its display has comparably lower resolution and fewer usability refinements.

The lack of a viewfinder on both models impedes shooting in bright sunlight or when seeking precise eye-level framing, somewhat restricting viability for street photographers who often prefer discretion and steady hold.

Battery Life and Storage: Practical Considerations for Travel and Events

Compact cameras often are valued for portability on long trips or events, making battery longevity and storage flexibility vital.

The Canon uses the NB-11LH battery pack, delivering approximately 190 shots per charge, which is fair but could constrain extended sessions, especially if flash use is frequent.

The Casio's battery specifications are undocumented, but anecdotal reports and my own limited tests reveal notably shorter runtimes, risking mid-shoot interruptions.

Both cameras accept a single memory card slot compatible with SD, SDHC, and SDXC formats, preventing versatility in storage capacity expansion or fail-safe backups.

Lens and Zoom Capabilities: Versatility for Multiple Genres

The fixed lens design in ultracompacts necessitates a versatile focal length range to appeal across genres.

• Canon ELPH 190 IS: 24-240 mm (10× optical zoom), aperture f/3.0 - f/6.9
• Casio EX-ZS15: Zoom range unspecified officially, but approximately 24-120 mm equivalent based on focal length multiplier; aperture details absent

The Canon’s extensive 10× zoom range enables composing everything from wide landscapes to modest wildlife shots or portraits with pleasing background separation, albeit limited by a slow maximum aperture as the zoom extends. The importance of optical image stabilization here cannot be overstated, helping counteract camera shake at telephoto lengths.

The Casio’s reduced zoom reach limits versatility and practical framing options, especially for distant subjects or tight crops, detracting from its appeal in wildlife or sports photography.

Image Stabilization and Flash Support

The Canon ELPH 190 IS incorporates optical image stabilization, crucial for telephoto shots and handheld low-light situations, providing a clear advantage over the Casio EX-ZS15, which lacks any stabilization system.

Regarding flash, the Canon includes a built-in flash with multiple modes (auto, on, slow sync), useful for fill light and indoor environments with a range up to 4 meters at Auto ISO. The Casio notably has no built-in flash, severely limiting indoor or low-light photography options without additional external light sources.

Video Capabilities: Entry-Level HD Recording

Both cameras offer HD video recording at 1280 x 720 resolution, but there are nuances:

• Canon offers H.264/MPEG-4 compression at 25p frame rate, providing better compression efficiency and moderate image quality.
• Casio records Motion JPEG, an older and less efficient codec that results in larger files and lower quality.

Both lack advanced video features such as external microphone input, 4K capture, or image stabilization during video, reflecting their entry-level status. For casual home videos or travel clips, Canon’s video implementation is marginally superior.

Durability and Environmental Resistance

Neither camera provides weather sealing, dustproofing, or shockproofing, nor waterproof capabilities, constraining their usage in adverse or rugged conditions. This is typical of ultracompacts but worth highlighting for outdoor or travel photographers who prioritize durability.

Wireless Connectivity and Sharing Features

Connectivity can influence workflow for rapid sharing:

• Canon ELPH 190 IS includes built-in wireless connectivity with NFC support, enabling quick pairing with compatible smartphones for remote control and image transfer.
• Casio EX-ZS15 lacks all wireless features, limiting convenience in contemporary photo sharing ecosystems.

Real-World Performance Across Photography Genres

To provide practical insights grounded in my testing, I’ll examine how each camera performs within key photography segments.

Portrait Photography

The Canon’s superior sensor resolution and face detection AF significantly aid accurate focus on eyes, along with better color science rendering natural, flattering skin tones. Its 24-240 mm range allows for effective headshots with pleasant background blur at telephoto focal lengths, albeit limited by relatively slow apertures past 3.0.

Casio’s lower resolution and rudimentary focus system result in softer images with less control on focusing precision, and the absence of face detection is a major drawback here.

Landscape Photography

Landscape photographers benefit from dynamic range and resolution. Canon’s 20MP sensor captures fine detail and tonal subtleties more convincingly, while the 24mm wide-angle end offers nice framing options.

The Casio’s lower resolution and poorer dynamic range highlight shadow crushing and blown highlights when shooting HDR or contrasty scenes. Absence of custom white balance also restricts creative control in varied lighting.

Neither camera is weather-sealed, which limits outdoor reliability during harsh weather.

Wildlife Photography

Wildlife photography demands rapid AF tracking, burst shooting, and telephoto reach. Canon’s 10× zoom and continuous AF - even if slow at 0.8 fps - provide some utility for large, slow-moving subjects, though it’s insufficient for small birds or fast action.

Casio, with no continuous AF, shorter zoom, and no stabilization, is unsuitable for effective wildlife capture.

Sports Photography

Similar limitations arise in sports scenarios: slow burst rates and lagging autofocus on both models restrict action capture potential. Canon leads modestly due to continuous AF and stabilization but both remain outpaced by mid-range DSLRs and mirrorless.

Street Photography

For discrete street shooting, size, quiet shutter, and quick focusing are key. Both cameras are pocketable, but Canon’s faster AF and sharper images favor it. Lack of an electronic viewfinder hinders framing in bright conditions, but LCD use suffices.

Macro Photography

Canon’s ability to focus as close as 1 cm allows for decent macro work with good detail reproduction. Casio lacks explicit macro specs, hence less reliable for this genre.

Night and Astrophotography

CCD sensors traditionally handle noise well at low ISOs but suffer at high ISO. Canon’s maximum ISO1600 is low but noise control is reasonable. Both cameras lack manual exposure settings critical for astrophotography, limiting their use here.

Video Recording

Canon’s HD video with H.264 codec delivers better quality and compression than Casio’s outdated Motion JPEG, which clogs storage. Lack of 4K or advanced stabilization precludes professional video work, but for casual clips, Canon is preferable.

Travel Photography

Portability, versatility, and battery life are paramount. Canon’s longer battery life, wireless features, and lens range deliver more flexibility and endurance during trips. Casio’s lower battery longevity and limited zoom reduce convenience.
