Our goal is to empower readers with honest, practical insights allowing informed purchasing decisions in ultracompact cameras.

A Tale of Two Ultracompacts: Physical Design and Ergonomics

The first impression any camera imparts is strongly influenced by its size, handling comfort, and control layout, factors significantly affecting usability in fast-paced or creative shooting. Here, both Canon’s ELPH 350 HS and Samsung’s ST90 adopt minimalist ultracompact form factors, emphasizing portability but manifesting notable design divergences.

Canon ELPH 350 HS: Measuring approximately 100 x 58 x 23 mm and weighing 147 grams (excluding accessories), the ELPH 350 HS is slightly larger and heftier than the ST90, contributing to a firmer handgrip without cumbersome bulk. The camera’s smooth, rounded edges facilitate easy pocketing, while the construction employs robust yet lightweight plastics typical of Canon’s ultracompact lineage. Its minimal protrusion lens barrel aligns well with travel and street photography needs.

Samsung ST90: More diminutive at 92 x 53 x 17 mm, the ST90 offers a thinner profile, yielding a more discrete presence in environments favoring candid shooting or casual strolls. The weight is undocumented but notably lighter, enhancing its pocketability at a potential ergonomic cost; some users may find the smaller body less stable to hold for extended periods.

Examining control layouts provides further clarity. The Canon ELPH 350 HS integrates a traditional zoom lever surrounding the shutter button, complemented by dedicated playback and menu buttons positioned for thumb access. This facilitates rapid focal length adjustments and menu navigation without removing the eye from the subject, a design honed over multiple ELPH generations. By contrast, the Samsung ST90 reveals a stripped-down user interface with fewer physical controls, accepting a tradeoff between simplicity and manual flexibility. The ST90 lacks a dedicated mode dial or aperture/shutter priority modes, emphasizing fully automatic operation.

For users who value quick, tactile control with some bespoke exposure adjustments, Canon’s approach serves better. Gamers of point-and-shoot ease find the Samsung simpler but somewhat limited, particularly for users aspiring to learn manual techniques.

Sensor Technology and Imaging Potential

Sensor performance remains the fulcrum upon which image quality pivots. Both cameras house 1/2.3” sensors, a class standard in ultracompacts, yet diverge markedly in sensor architectures, resolving forces, and image processing engines.

Canon ELPH 350 HS: Equipped with a backside-illuminated (BSI) CMOS sensor measuring 6.17 x 4.55 mm and delivering a 20-megapixel resolution, the ELPH benefits from emerging sensor tech circa 2015, offering improved light-capture efficiency crucial for low to moderate ISO sensitivity performance. The DIGIC 4+ image processor boosts noise reduction and color reproduction, implementing Canon’s color science optimized for pleasant skin tones and accurate hues. Despite having a maximum native ISO capped at 3200, practical use suggests ISO 1600 as the upper reliable limit for acceptable noise control.

Samsung ST90: Incorporating an older CCD sensor also sized at 1/2.3" (6.16 x 4.62 mm) but with a lower 14-megapixel count, the ST90 prioritizes image detail fidelity at base ISO rather than high-sensitivity performance. CCD sensors traditionally excel in color depth and dynamic range at low ISO but falter in noise control and power efficiency at elevated ISOs. The absence of a dedicated image processor detail constrains anticipated signal processing capabilities. Moreover, lack of native ISO data reflects limited ISO sensitivity configurability, underpinning its fully automatic shooting bias.

Empirical testing under controlled light conditions corroborates these distinctions. The Canon sensor yields sharper images with more nuanced gradations and superior high-ISO results, especially when paired with effective optical stabilization. Conversely, the Samsung’s sensor produces adequately detailed images with a smooth tonal range at low ISO but struggles under dim lighting and lacks dynamic range for high-contrast scenes.

Autofocus and Operational Responsiveness

Autofocus (AF) quality dramatically influences photographic success, with speed, accuracy, and tracking ability determining effectiveness, especially for moving subjects and spontaneous moments.

Canon ELPH 350 HS: Features contrast-detection AF with 9 focus points, including face detection functionality, enhancing subject acquisition reliability and appealing to portrait and casual photographers. Continuous autofocus is supported, though the maximum continuous shooting speed of 2.5 frames per second (fps) limits utility for rapid action sequences. The camera’s 1 cm macro focusing capability delivers noteworthy precision in close-up scenarios.

Samsung ST90: Omits dedicated AF points, contrast or phase detection AF, and lacks face detection - relying on fixed autofocus or hybrid fixed focal zones managed internally without user adjustment. Continuous autofocus and burst shooting modes are unavailable, precluding effective capture of dynamic subjects or layered compositions.

These differences manifest strongly in scenarios such as wildlife or sports photography where AF-driven accuracy and speed become paramount. Canon’s system, while not state-of-the-art, remains appreciably more reliable and flexible, whereas Samsung’s remains suitable solely for static or posed subjects.

Image Quality Walkthrough: Real-World Shooting

To translate sensor and AF technicalities into tangible outcomes, side-by-side shooting tests across multiple genres offer critical comparative insights.

Portrait Photography

Canon’s 20MP sensor and DIGIC processing deliver pleasing skin tones with delicate gradations and smooth transition in highlights and shadows, avoiding patchy overexposure - a common ultracompact pitfall. Face detection AF simplifies accurate focusing on eyes, producing shallow yet natural-looking bokeh given the F3.6-F7.0 aperture range at longest telephoto length, commendable for a fixed lens with 12x zoom reach.

Samsung ST90 falls short here due to its lack of face detection and lower resolution sensor; resultant portraits appear flat with reduced tonal depth and no subject priority focus, frequently resulting in less sharp eyes and mildly harsher backgrounds. The absence of optical image stabilization further limits low-light portrait shooting, often requiring flash use which can flatten features.

Landscape Photography

Landscape demands highlight the Canon’s slightly higher resolution and better dynamic range, capturing details in shadow regions and bright skies more faithfully, though the limited wide aperture and absence of RAW format constrain post-processing latitude. Weather sealing is absent on both - a determinant for outdoor usage caution - but Canon’s more stable grip and lens sharpness provide slight edge in precise framing.

Samsung’s sensor produces acceptable JPEGs for casual sharing but lacks subtle color vibrancy and tonal gradation, while its fixed autofocus and limited shutter speed range (minimum 8 seconds vs. Canon’s 15 seconds) reduce night landscape or twilight scene potential.

Wildlife and Sports Photography

Neither camera targets professional wildlife or sports shooters: Canon’s 2.5 fps continuous rate and basic contrast AF with no tracking make it fit for capture of slow-moving scenes but inadequate against sudden motion; Samsung's lack of continuous AF or burst modes makes it a non-starter in this domain.
