Canon PowerShot S120 vs Canon PowerShot SX740 HS: An In-Depth Comparison for Discerning Photographers

Selecting a high-performance compact camera requires careful scrutiny of technical capabilities, operational ergonomics, and alignment with specific photography disciplines. The Canon PowerShot S120 and Canon PowerShot SX740 HS represent two distinct entries within Canon’s compact range, catering respectively to enthusiasts prioritizing low-light performance and portability, and zoom aficionados seeking extreme focal length versatility. Drawing from extensive hands-on testing and industry-standard evaluation protocols, this comparison unpacks each model’s strengths, limitations, and real-world usability across comprehensive photographic use cases.

Physical Design and Handling: Size, Ergonomics, and Controls

Analyzing the physical dimensions and ergonomics underlines intrinsic workflow differences. The Canon S120 measures approximately 100×59×29 mm and weighs 217 grams, embodying a truly pocketable form factor with a sleek, minimalist profile. By contrast, the SX740 HS is slightly larger and heavier at 110×64×40 mm and 299 grams due to its extended zoom mechanism and reinforced lens barrel.

From a tactile standpoint, the S120’s subdued size lends well to street photography and travel scenarios demanding unobtrusive operation. However, those with larger hands may find its compactness compromises grip comfort over prolonged shoots. The slightly bulkier SX740 HS offers a more substantial handhold, beneficial for stability during telephoto use and extended sessions.

Control schemes reflect their intended user base: The S120 features a simplified, tactile interface with a touchscreen-enabled rear 3-inch TFT PureColor II G LCD at 922k dot resolution, supporting touch autofocus and menu navigation. The SX740 HS opts for a tilting 3-inch LCD of identical resolution but omits touchscreen input, requiring reliance on physical buttons and dials. This removes an immediate focusing convenience but arguably reduces accidental input during rapid shooting.

Although neither model offers an electronic viewfinder, which is arguably a limiting factor for composition precision in bright conditions, the S120’s smaller lens and body aid discreet shooting, whereas the SX740 HS’s zoom lens inherently draws more attention.

Sensor Technology and Image Quality

The S120 incorporates a 1/1.7-inch BSI-CMOS sensor with a 12-megapixel resolution, equating to a physical sensor area of approximately 41.52 mm². Although modest by modern standards, this sensor size enhances photon-capturing capabilities, yielding improved noise control and dynamic range compared to smaller sensors.

Conversely, the SX740 HS employs a smaller 1/2.3-inch BSI-CMOS sensor with 21 megapixels on a 28.07 mm² area. The increased pixel density on a smaller sensor often results in more noise at elevated ISOs and a narrower dynamic range ceiling, which was confirmed by measured DxO Mark scores being unavailable for this model but anticipated lower than the S120’s 56 overall score.

In practical shooting, the S120 produces cleaner images across ISO 80–12800 native range, notably excelling at low-light conditions. The SX740 HS maxes out at ISO 3200 native sensitivity and lacks RAW capture support, limiting post-processing latitude and professional workflow integration.

Autofocus System and Performance

Both cameras rely on contrast-detection autofocus systems augmented with face-detection capabilities, but with subtle operational variances affecting fast-moving subject capture.

• The S120 offers 9 discrete AF points and supports AF modes including single, continuous, tracking, selective, and center-area AF with touch-to-focus on the rear screen.
• The SX740 HS lacks specified AF point counts and limits operation to single, continuous, and tracking AF modes but omits touch AF, requiring manual joystick or button navigation.

Neither employs phase-detection pixels for hybrid autofocus advantages, which constrains speed and accuracy in dynamic scenarios such as sports or wildlife photography. However, the S120’s touch AF and slightly more sophisticated AF area selection offer finer control for portrait and street photography where precise focus on eyes or faces matters.

Lens and Zoom Capabilities

This comparison strongly pivots on the optical systems:

The S120’s fast f/1.8 aperture at wide angle contributes significantly to improved low-light shooting and shallower depth of field effects, enhancing portrait quality with pleasant background blur (bokeh). In contrast, the SX740 HS compromises on aperture speed (f/3.3 wide, tapering to f/6.9 telephoto), which, combined with the small sensor, limits low-light and bokeh rendition.

The SX740 HS’s astounding 40x zoom range is unparalleled for wildlife, sports, and travel photography where versatility and reach are paramount, but this comes at the expense of aperture speed and potentially compromised image quality at extreme telephoto lengths due to diffraction and sensor limitations.

The S120’s macro focusing capability starting at 3 cm is sufficient for casual close-ups, while the SX740 HS’s 1 cm minimum focusing distance allows for more detailed macro captures, although the narrower aperture and digital zoom cropping sometimes degrade results.

Display and User Interface

Both cameras feature 3-inch LCD screens with 922k dot resolution. However, the S120’s touchscreen interface affords more intuitive AF point selection and menu navigation - valuable for precise manual focusing and quick setting changes during live view. The SX740 HS’s non-touch tilting screen enhances compositional flexibility, especially for low or high angles and selfie framing, as it flips upward 180 degrees, explicitly marketed as selfie-friendly.

The omission of touchscreen on the SX740 HS may frustrate users accustomed to touch responsiveness on autofocus and zoom control, but physical button access offers reliability in active conditions where touch inputs can erratically respond due to moisture or gloves.

Continuous Shooting, Video, and Multimedia Capabilities

The S120 edges out in burst rate speed with 12 fps, suitable for capturing fast action in some sports or street scenarios, though buffer capacity and autofocus tracking limit sustained sequences.

The SX740 HS supports 4K UHD video at 30p, a modern inclusion absent in the S120’s capabilities, which caps at Full HD 1080p. This offers more detailed video capture for travel vlogging, documentary, or casual filmmaking. However, the lack of external mic inputs on either camera restricts audio recording quality and professional video workflows.

Both models include optical image stabilization to smooth handheld video footage, with the SX740 HS benefitting from updated DIGIC 8 processor enhancements, improving noise reduction and video encoding.

Battery Life, Storage, and Connectivity

Battery endurance has critical implications for travel and professional use:

• The S120 utilizes the NB-6LH battery, rated for approximately 230 shots per charge under normal conditions.
• The SX740 HS lacks a specified battery model but advertises approximately 265 shots, indicating a moderate improvement, likely influenced by more efficient DIGIC 8 processing.

Both cameras accept SD/SDHC/SDXC memory cards, with SX740 HS supporting UHS-I for faster write speeds.

Connectivity-wise, the SX740 HS supports Bluetooth and NFC in addition to Wi-Fi, enabling quicker pairing with smart devices for remote control and image sharing. The S120 offers built-in Wi-Fi but lacks Bluetooth/NFC, potentially limiting convenience in wireless workflows.
