Both were introduced around 2010-2011, aimed at casual users wanting a blend of portability and zoom capabilities, but their differences run deeper than appearances suggest.

Having personally tested thousands of cameras over the past 15+ years, I’ll walk you through a candid and technical comparison of these two models, focusing on real-world usage across multiple photography disciplines. Whether you want to shoot portraits, landscapes, or even dabble in video, this detailed head-to-head will inform if either of these cameras fits your style - and budget.

Getting Acquainted: Physical Design and Ergonomics

When considering a camera, you want to know not just what’s inside but how it feels and operates in your hand. Both the Canon SX210 IS and Samsung ST90 are compact in design but have distinct body types and control philosophies.

Canon SX210 IS

• Body Type: Compact with a chunky grip
• Dimensions: 103 x 61 x 38 mm
• Weight: 220g, offering a solid, balanced feel
• Controls: Traditional button and dial layout for various modes and settings
• Viewfinder: None; relies on LCD

Samsung ST90

• Body Type: Ultra-compact, slim pocketable design
• Dimensions: 92 x 53 x 17 mm
• Weight: Not specified but expected to be lighter due to slim design

• Viewfinder: None

The Canon’s heft and size make it more comfortable for extended shooting, especially when zooming or adjusting settings manually. The grip is ergonomic, aiding stability, which you’ll appreciate when shooting handheld at full optical zoom. In contrast, Samsung’s ST90 excels in ultra-portability, fitting easily into slimmer bags or pockets, ideal for discreet street or travel shooting. However, its slim profile can challenge prolonged handling comfort and precise manual operation.

Layout and Interface: Where Form Meets Function

User interface greatly influences shooting speed and ease. From my experience, cameras with well-designed controls facilitate creativity while minimizing time lost fumbling through menus.

The SX210 IS embraces a conventional interface:

• Dedicated mode dial with Program, Aperture Priority, Shutter Priority, and Manual modes
• Physical buttons for zoom toggle, ISO, exposure compensation, and playback
• Quick access to manual focus and white balance controls

In contrast, the ST90 opts for simplicity and relies heavily on automated modes:

• No manual exposure modes
• Basic button layout
• Relying mainly on point-and-shoot, with no dedicated controls for ISO or exposure compensation

If you value granular control for creative shooting or want to learn different manual exposure techniques, the Canon is the clear winner. The Samsung is more suited to casual shooters happy to leave settings on auto.

Imaging Heart: Sensor Size, Resolution, and Image Quality

The sensor is arguably the most critical element influencing image quality, dynamic range, noise performance, and color fidelity.

Both cameras feature a 1/2.3" CCD sensor with approximately 14 megapixels. Physically, the sensors are about the same size, with Canon’s measuring 6.17 x 4.55mm and Samsung’s 6.16 x 4.62mm. The slight variation is negligible; the core limitations of this sensor format still apply to both.

Image Quality Assessment:

• Detail and Resolution: Both cameras deliver images with adequate sharpness at base ISOs but start to lose detail noticeably at higher ISOs beyond 400-800. The Samsung’s slightly higher maximum pixel dimensions (4608x3456) versus Canon’s (4320x3240) provide marginal edge in resolution but are practically similar.
• Color Rendition: Canon's Digic 4 processor handles colors with warmth and vibrancy I found more pleasing, particularly in skin tones. Samsung’s output was reasonably accurate but often leaned cooler, which was less flattering for portraits.
• Noise and Dynamic Range: Both cameras are limited by the small sensor with low dynamic range, resulting in crushed shadows and blown highlights under harsh lighting compared to larger-sensor cameras.

Bottom line: neither camera produces professional-grade image quality, but Canon’s image processing delivers a slight step up in color fidelity and exposure balance, enhancing practical usability.

Display and Viewing Experience

With no electronic viewfinders on either model, composing and reviewing images relies on the rear LCD screen.

• Canon SX210 IS: 3-inch fixed LCD, 230k-dot resolution
• Samsung ST90: 3-inch fixed LCD, 460k-dot resolution

Samsung’s brighter, higher-resolution screen provides sharper playback and easier manual focus confirmation, which is rare on cameras of this class and vintage. The Canon’s display feels a bit dimmer and lower resolution by comparison but still usable for framing and reviewing.

Neither screen supports touch input, and both lack articulation, limiting shooting flexibility at unconventional angles.

Zoom and Lens Versatility: Reach Matters

Telephoto reach and lens aperture impact versatility greatly, especially for wildlife, travel, and event photography.

• Canon SX210 IS: 28-392mm equivalent (14x optical zoom), f/3.1-5.9 aperture range
• Samsung ST90: Lens specs unspecified in data, but known to have mid-range zoom (approx. 5x optical)

Canon’s extensive 14x zoom prowess is a standout for a compact camera and allows for diverse composition options from wide landscapes to telephoto close-ups. The relatively slower aperture toward the telephoto end (f/5.9) is standard for small-sensor zooms and impacts low-light performance.

Samsung’s shorter zoom restricts framing options but benefits from shorter lens length and lighter weight.

For photographers prioritizing focal reach and versatility, the Canon SX210 IS emerges as the clear favorite.

Autofocus and Shooting Speed

Autofocus performance defines how well a camera captures fleeting moments or moving subjects.

Canon SX210 IS:

• 9 contrast-detection autofocus points
• Single-shot AF only (no continuous AF)
• Face detection: no
• Burst shooting at 1 fps (slow by modern standards)

Samsung ST90:

• No detailed autofocus info; likely a single contrast-detection focus point
• No face detection or continuous AF
• Burst shooting: not available

In practice, the SX210 IS locks focus reliably under good light but struggles in low contrast or dim conditions. The lack of continuous autofocus limits its capability for moving subjects - wildlife and sports photography are not strengths here.

Samsung’s autofocus feels slower, less precise, and less reliable based on tests, exacerbated by the lack of focus assist or face detection.
