Canon PowerShot SX730 HS vs Samsung SL720: A Comprehensive Comparative Analysis

In the landscape of compact digital cameras, discerning the best choice often hinges on the specific photographic needs, technical performance, and ergonomic considerations. This detailed comparison examines two distinct compact cameras released nearly a decade apart: Canon’s PowerShot SX730 HS (2017), a superzoom small sensor compact, and Samsung’s SL720 (also referred to as PL70, launched in 2009), an ultracompact point-and-shoot. Both cameras cater to users looking for portability combined with specific feature sets, yet their underlying technologies diverge significantly. Having personally tested thousands of cameras across different categories, this analytical review will unpack their construction, imaging capabilities, and real-world usability in a variety of photographic disciplines.

Core Design and Ergonomics: Handling in Real Conditions

The first tangible aspect influencing image making is the physical design and control layout. The Canon SX730 HS positions itself as a compact superzoom camera with significant reach but weighs 300 grams and measures 110 × 64 × 40 mm. The Samsung SL720, by contrast, is markedly more diminutive and lighter at 168 grams, with smaller dimensions 92 × 61 × 23 mm, trading optical versatility for compactness.

From hands-on experience, the Canon’s body offers a more substantial grip area and button placement conducive to extended shooting and manual adjustments. Samsung’s SL720, being ultracompact, sacrifices deeper ergonomics for pocketability. This design trade-off impacts comfort in longer shooting sessions, particularly for users intending to leverage manual controls, which Samsung nearly omits.

In field testing, the SX730 HS’s physical heft contributes to steadier handheld shots at longer focal lengths, especially when the optical zoom is fully extended, where camera shake is a concern. Samsung’s SL720 is better suited for casual carry-and-shoot scenarios where ultimate portability is prioritized.

Sensor Architecture and Image Quality: Highlights and Limitations

Both cameras utilize a 1/2.3" sensor format, which classifies them as small-sensor compacts, but they differ in sensor technology and resolution fundamentally influencing image outcome.

• Canon SX730 HS uses a backside-illuminated CMOS sensor at 20.3 megapixels.
• Samsung SL720 houses an older CCD sensor offering 12 megapixels.

The CMOS sensor in the Canon provides notable benefits: superior noise control at high ISO, improved dynamic range, and faster data readout enabling high-speed shooting modes. Conversely, the Samsung’s CCD sensor is known for delivering comparatively good color rendition but suffers from higher noise at elevated sensitivities and slower response times.

The SX730 HS’s higher resolution (5184 x 3888 max image size) enables more significant cropping flexibility, while Samsung’s 4000 x 3000 pixel output, though adequate for casual prints, is less versatile in professional workflows.

Given the sensor size equivalence, dynamic range remains inherently limited, but Canon’s DIGIC 6 processor optimizes sensor output better, delivering improved detail retention in shadows and highlights.

Display and User Interface: Interaction with the Camera

Display technology profoundly affects shooting convenience and image review efficiency.

• The Canon SX730 HS features a 3-inch tilting LCD with a resolution of 922k dots but lacks touch input.
• Samsung SL720 offers a fixed 2.7-inch LCD with 230k dots - a significantly lower resolution.

Canon’s articulated screen design provides increased compositional flexibility, especially useful in complex shooting angles, macro, and street photography scenarios. The higher pixel density enables sharper live view and playback, facilitating fine focus confirmation and menu navigation, which benefits both enthusiasts and pros seeking precision.

Samsung’s fixed screen serves basic framing needs but may frustrate users due to limited viewing angles and resolution, with no touchscreen functionality or live histogram display - tools commonplace in modern cameras.

Autofocus Systems: Speed and Accuracy Under Diverse Conditions

Autofocus is a critical performance vector across photographic genres, and these two differ widely here.

• The Canon SX730 HS employs contrast-detection autofocus enhanced with face detection, center and multi-area AF modes, continuous AF, and limited tracking.
• The Samsung SL720 uses only contrast-detection AF without face or tracking capabilities.

In practical testing, Canon’s AF system proves significantly faster and more reliable, accomplishing focus in well under a second under adequate lighting, and maintaining reasonable accuracy in moderately low light. Eye detection and face recognition - though rudimentary compared to modern standards - assist in portraiture and casual shooting.

Samsung’s AF, being older and rigid, lagged in acquiring focus especially in low-light or moving subjects. The absence of AF tracking makes the SL720 unsuitable for action, wildlife, or sports photography.

Optical Systems: Focal Range and Aperture Impacts on Use Case

The lenses fitted to these cameras reveal their intended photographic emphases.

• Canon SX730 HS’s lens covers a vast 24–960 mm equivalent focal range (40x optical zoom). Maximum aperture ranges from f/3.3 (wide) to f/6.9 (telephoto).
• Samsung SL720 sports a 28–102 mm equivalent zoom (3.6x optical) with a brighter f/2.8–5.7 aperture spread.

Canon’s elongated zoom span offers unmatched versatility in this segment, capable of close macro shots down to 1 cm and distant wildlife or sports capture. However, the trade-offs include narrower apertures at telephoto, leading to limited low-light capability and slower autofocus in that range.

Samsung’s lens excels in wider apertures at the base, beneficial in low light and portraits, but with limited zoom flexibility, restricting reach.
