Both target entry-level users but approach photography differently.

Drawing on years of hands-on testing and evaluations, we'll explore each camera’s strengths, weaknesses, and real-world performance across key photography disciplines. Whether you seek a versatile travel companion, a beginner-friendly first camera, or an affordable pocket shooter, this comparison will help you find your match.

Visualizing Size and Ergonomics: Compact Superzoom vs Ultracompact Snapper

Before we dive deeper, let's consider how these cameras feel in your hands - ergonomics affect how easily and comfortably you shoot.

• Canon SX170 IS: Larger and chunkier at 108 x 71 x 44 mm and weighing 251g, it feels solid with pronounced grip contours. This size accommodates the long 28-448mm equivalent superzoom lens and provides physical controls that improve handling for enthusiasts.
• Samsung ST93: Ultra-slim and pocket-friendly at 92 x 53 x 17 mm, weighing just 110g, the ST93 slips unobtrusively into any bag or pocket. However, it sacrifices ergonomics and control comfort due to its tiny body.

In practice: You’ll appreciate the Canon’s heft and grip if you plan longer shooting days or prefer manual adjustments. The Samsung’s diminutive size is ideal for casual snapshots when pocketability matters most.

Control Layout and Top-Down Handling

Good button placement and dials facilitate easier operation, especially for quick settings changes.

• Canon SX170 IS: Offers dedicated shooting mode dial, zoom toggle, and buttons for exposure compensation, ISO, and flash. With manual focus and exposure modes supported, tactile controls empower photographers seeking creative input.
• Samsung ST93: Very minimal controls; no manual focus or exposure options. Most settings are auto-managed, reflecting its point-and-shoot simplicity. This suits beginners or users valuing ease over versatility.

Expert tip: If you prefer control at your fingertips, Canon’s layout is superior. The Samsung offers simplicity but at the cost of flexibility and responsiveness.

Sensor Technology and Image Quality: Inside the Lens

The sensor is the heart of image quality. Let’s analyze sensor specs and expected performance.

Both cameras use outdated 1/2.3-inch CCD sensors with identical megapixel counts. This sensor size limits high ISO noise control and dynamic range, common in entry-level compacts.

• Canon SX170 IS's max ISO 1600 is adequate with noise control that does not degrade images severely up to ISO 800. Above this, noise becomes noticeable.
• Samsung ST93's extended max ISO 3200 sounds promising but in real-life low-light conditions produces heavy noise and color shifts. Additionally, no manual ISO options limit control.

Bottom line: Both cameras deliver decent daylight image quality but fall short under challenging lighting. The Canon’s sensor and Digic 4 processor handle noise slightly better overall.

LCD and User Interface: What You See Matters

Your ability to preview and review images depends heavily on the display quality.

• Canon SX170 IS: 3-inch fixed TFT LCD with 230k-dot resolution. Brightness and colors are acceptable but somewhat limited in outdoor sunlight.
• Samsung ST93: Also 3-inch but with higher 460k-dot resolution, making for crisper image previews. However, the glossy screen suffers from reflections.

Neither camera offers touchscreen operation, and both lack electronic viewfinders.

User insight: For daylight shooting and composing, Samsung’s higher resolution screen offers sharper previews. Canon’s interface provides more menu depth and creative options but is less crisp.

Real-World Photography Tests Across Genres

Let’s test how these cameras perform under the most common photographic situations.

Portraits: Skin Tone Accuracy and Background Rendering

• Canon SX170 IS: Although it lacks a large sensor for creamy bokeh, the long zoom allows subject isolation at telephoto. Face detection autofocus works reliably, properly locking onto eyes for sharp focus. Skin tones render naturally, consistent with Canon’s reliable color science.
• Samsung ST93: No face detection autofocus, only digital contrast-based focus with average speed and accuracy. Skin tones tend toward flatness and loss of subtle hues. Also, the short zoom limits background compression and blurring.

Verdict: Canon’s SX170 IS offers better portrait potential and results likely to please beginners moving beyond snapshots.

Landscape Photography: Resolution and Dynamic Range

With modest sensor performance, landscape quality depends on lens sharpness and dynamic range handling.

• Canon SX170 IS: The longer zoom supports varied compositions but wide-angle is only 28mm equivalent - less expansive than many competitors. Dynamic range is narrow, with highlights clipping easily on bright scenes. Image detail is adequate, though diffraction softens at smaller apertures.
• Samsung ST93: Fixed lens with unknown focal length limits creative framing. The CCD sensor and processing reveal lower shadow detail and highlight rolloff.

Recommendation: For beginners focusing on landscapes, neither excels by modern standards, but SX170’s flexibility edges out Samsung in usable framing options.

Wildlife and Sports: Autofocus Speed & Burst Rate

Capturing fast action requires responsive autofocus and quick continuous shooting.

Neither camera is designed for fast-moving subjects. The Canon’s single frame per second is the upper limit, while the Samsung’s slower processing further hampers action shots. AF tracking on Canon is rudimentary but helps a bit.

Takeaway: If wildlife or sports photography is your goal, these cameras are not suitable; consider DSLRs or mirrorless with higher frame rates and better AF.

Street Photography: Discreteness and Low-Light Performance

Street photographers need stealth, instant responsiveness and decent low-light ability.

• Samsung ST93: Ultra-compact, light, and near-silent in operation. Perfect for unobtrusive shooting. Low-light performance suffers due to weak sensor and electronic noise.
• Canon SX170 IS: Larger size may attract attention but offers optical image stabilization, useful for dim lighting. Slightly higher max shutter speed (1/3200s) helps with bright day conditions.

Insight: Samsung suits candid street photography well; Canon provides better image quality but at a size cost.

Macro Photography: Focusing Precision and Magnification

• Canon SX170 IS: Macro focusing range down to 1cm is excellent for close-ups. Optical stabilization aids sharpness handheld.
• Samsung ST93: No macro specification, and its autofocus struggles on close subjects.

For macro enthusiasts, Canon is clearly superior.

Night and Astrophotography: High ISO and Exposure Options

Low light demands the ability to control ISO and shutter speeds.

Canon’s manual modes and longer exposure options allow some experimentation with night shots and light trails, though sensor noise is a limiting factor. Samsung’s lack of manual exposure modes makes night or astro photography impractical.

Video Capabilities: Resolution and Stabilization

Both cameras are limited in video.

Canon’s stabilized footage results in smoother handheld video; Samsung’s lack of stabilization yields shakier clips. Both are adequate for casual clips but not suitable for serious video work.

Travel Photography: Versatility, Battery Life, Size, and Weight

• Canon SX170 IS: Offers effective zoom range covering wide-angle to super-telephoto, stabilized lens, and 300 shots per charge on a rechargeable battery. This versatility makes it travel-ready when you want an all-in-one camera.
• Samsung ST93: Very portable but limited zoom, no image stabilization, and unspecified battery life. Its ease of carry is balanced against lesser creative shooting potential.

If you want one camera for most travel scenes, Canon is the more practical pick; Samsung is backup-friendly.
