Choosing a small sensor superzoom camera entails balancing optical reach, sensor capability, handling, and modern connectivity features. Canon’s PowerShot series has long served enthusiasts seeking compact versatility with extensive zoom ranges. The Canon SX240 HS, announced in early 2012, and its 2017 successor the SX730 HS both target this niche - but their five-year evolution reflects notable technological progress as well as compromises tied to their compact designs.
Having personally tested thousands of cameras across years in diverse shooting conditions, this comparison focuses on practical usability, image quality nuances, and workflow considerations that matter most to discerning users. From sensor behavior to autofocus performance, plus the ergonomics demanded by varying shooting styles, this analysis guides you through the core distinctions of these two Canon superzooms.
Body Design and Handling: Compact Convenience Meets Control Limitations
The Canon SX240 HS and SX730 HS both adopt compact form factors emphasizing portability; however, subtle dimensional and handling differences impact real-world comfort and steadiness.
-
Canon SX240 HS:
Dimensions measure 106 × 61 × 33 mm and weigh a mere 224 g. The lightweight build favors casual travel and impromptu captures but can feel slightly unstable when shooting at longer focal lengths, due to less substantial grip contours. The controls are straightforward with limited customizability, suitable for users desiring a simple interface without overwhelming dials or buttons. -
Canon SX730 HS:
Slightly larger at 110 × 64 × 40 mm and 300 g, the SX730 HS adds heft that contributes to steadier handling, especially when employing its 40x zoom. The thicker body accommodates a tilting rear LCD and a broader control layout, which generally improves operational speed and tactile feedback. Although still fundamentally a pocket-friendly design, this model better balances compactness with grip security.
Neither camera includes a viewfinder, which is a notable consideration in bright outdoor shooting. This heightens reliance on their respective LCD screens.
Screen and Viewfinder Analysis: From Fixed LCD to Tilting Flexibility
Screen technology directly influences compositional workflow and on-the-go usability.
Feature | Canon SX240 HS | Canon SX730 HS |
---|---|---|
Screen Type | Fixed PureColor II TFT LCD | Tilting LCD (screen tech not specified) |
Screen Size | 3.0 inches | 3.0 inches |
Resolution | 461k dots | 922k dots |
Touchscreen | No | No |
Selfie-Friendly | No | Yes (due to tilting screen) |
Viewfinder | None | None |
The SX730 HS’s higher-resolution tilting screen offers more precise framing and review capabilities. Its articulating mechanism enhances shooting versatility - particularly for low-angle or selfie-style captures, which the SX240 HS cannot accommodate.
However, both cameras lack electronic viewfinders (EVFs), which restricts compositional reliability in direct sunlight. This might be a decisive negative for users expecting complete control in variable lighting conditions.
Sensor and Image Quality: Resolution Gains and Noise Handling
Both cameras utilize the same physical sensor size: a 1/2.3-inch BSI-CMOS sensor with an area of 28.07 mm², a standard in compact superzooms offering significant zoom without bulk. Despite this shared baseline, sensor improvements and processing upgrades yield markedly different image outcomes:
Specification | Canon SX240 HS | Canon SX730 HS |
