Canon PowerShot SX540 HS vs SX740 HS: The Definitive Comparison for Small Sensor Superzoom Shooters

In today’s crowded compact superzoom market, Canon’s PowerShot series has long offered compelling, affordable options for photographers seeking big zoom ranges without lugging heavy gear. Within this lineup, the Canon PowerShot SX540 HS (released in early 2016) and its successor, the SX740 HS (arrived mid-2018), stand out as popular choices. On spec sheets alone, they seem closely matched - yet their real-world capabilities and user experience show important differences.

After extensive hands-on testing and technical benchmarking of both models, I’m sharing a detailed, practical comparison tailored to enthusiasts and professionals curious about these cameras’ strengths and limitations. Whether your interest lies in travel, wildlife, portraiture, or video, this guide breaks down the nuances you won’t find just from specs - covering everything from sensor performance to autofocus behavior, ergonomics, and image quality.

A Tale of Two Cameras: Body Design and Handling

At first glance, the Canon SX540 HS and SX740 HS share Canon’s typical point-and-shoot styling cues, but a closer look reveals notable ergonomic shifts reflecting the evolution in compact zoom cameras over two years.

• SX540 HS: This model sports a bridge-style SLR-like body with a chunky grip and broad external controls. With dimensions at 120 × 82 × 92mm and a weight of 442g, it offers a tactile, substantial feel in the hand - comforting during extended shooting sessions or when using its massive 50x 24-1200mm equivalent zoom.

• SX740 HS: More compact and streamlined, the SX740 measures just 110 × 64 × 40mm and weighs a mere 299g, shaving over 140 grams and adopting a true compact form. Despite this size reduction, it still manages a decent, though less beefy, grip area - ideal for travelers prioritizing portability.

From a usability standpoint, the SX540’s dedicated dials and buttons allow faster manual adjustments without diving into menus, a boon for photographers who like granular, tactile control. The SX740, meanwhile, switches to a more minimalist layout, sacrificing some physical controls in favor of ease of carry and operation by casual users.

My takeaway: If you prioritize handling comfort and quicker access to manual controls, the SX540’s body style feels more traditional and robust. Conversely, the SX740’s smaller footprint excels if ultralight travel or street photography discretion is paramount.

Sensor and Image Quality: Are They Twins or Distant Cousins?

Both the SX540 HS and SX740 HS utilize a 1/2.3-inch backside-illuminated CMOS sensor measuring approximately 6.17 × 4.55 mm, with around 20MP effective resolution (20MP in the SX540 and 21MP in the SX740). This sensor size is common in superzoom compacts but inherently limits dynamic range and noise performance compared to larger APS-C or full-frame sensors.

Key sensor-related insights from my side-by-side tests include:

• Resolution & Detail: Both produce images with a maximum resolution of 5184 × 3888 pixels, offering sufficient detail for casual prints and web sharing. The SX740’s one-megapixel bump makes little perceptible difference in real-world sharpness.

• Dynamic Range & Color Depth: Using standardized RAW (although neither camera shoots RAW, so JPEG processing is key), both cameras deliver moderate dynamic range. The SX740 benefits from the newer DIGIC 8 processor’s improved noise reduction and color rendering, yielding slightly cleaner shadows and more accurate color reproduction under varied lighting.

• ISO Performance: Native ISO tops out at 3200 on both cameras. However, the SX740’s upgraded processor handles higher ISOs marginally better, making it less noisy for indoor or evening shooting.

• Anti-aliasing Filter: Both retain the traditional optical low-pass filter to combat moiré, which slightly softens images but helps prevent artifacts - a sensible choice given the long telephoto zoom possibilities.

To sum it up, while their sensors are fundamentally the same size and resolution, the processing improvements in the SX740 translate to incrementally better image quality - especially in challenging lighting conditions where noise and color fidelity matter.

The Viewfinder and Screen: Evolution in Display Feedback

Neither camera includes an electronic viewfinder, a cost-cutting omission common in this class, so framing must happen on the rear screen.

• SX540 HS: A fixed, non-touch 3.0-inch LCD with a modest 461k-dot resolution - adequate but admittedly dimmer and less sharp, which can make composing in bright sunlight a challenge.

• SX740 HS: Steps up notably with a 3.0-inch tilting screen boasting 922k-dot resolution, nearly double the pixel density, and flexibility in angles. This makes it easier to shoot at waist level, high angles, or for selfies - a function the SX740 explicitly supports with “selfie-friendly” design.

Sony’s tilting screen here is a major ergonomic advantage for many photographic styles, from street to travel and vlogging.

Practical insight: The SX740’s improved screen markedly enhances user experience, especially in the field under varied lighting. The lack of touchscreen is a downside for some, but the added tilting mechanism almost compensates.

Autofocus and Burst Performance: Tracking the Action

Autofocus and continuous shooting capabilities are crucial in genres like wildlife, sports, and street photography. Here the two cameras diverge notably.

• SX540 HS: Employs contrast-detection autofocus with face detection, but lacks AF tracking or animal eye AF. Continuous shooting records roughly 6 fps - a decent speed for casual use, though with some lag between shots under difficult focus conditions.

• SX740 HS: Moves forward with improved AF algorithms offering AF tracking, which aids in maintaining focus on moving subjects. Its continuous shooting rate doubles to 10 fps, offering a significant advantage for fast-paced capture.

Neither can compete with mirrorless systems’ hybrid AF or DSLR phase-detect, but for a small sensor bridge/compact, the SX740 is clearly better optimized for decisive moments.

In my field tests - tracking a fast-moving dog, for example - the SX740 had fewer focus drops and higher keeper rates. Yet both cameras’ autofocus lag becomes apparent in very low light or challenging contrast scenarios.

Zoom Range and Lens Characteristics: Versatility vs Reach

One of the biggest selling points for both models is the extensive zoom capability.

• SX540 HS: Features a 50x optical zoom ranging from 24mm ultra-wide to a staggering 1200mm equivalent telephoto, the longest in this comparison. Aperture ranges from f/3.4 at wide to f/6.5 at max telephoto.

• SX740 HS: Drops to a 40x zoom reaching 960mm equivalent focal length, slightly less reach but still very versatile. Aperture range is marginally smaller at f/3.3 to f/6.9.

Longer zooms increase possibilities but exacerbate camera shake and reduce sharpness at extreme telephoto ends. Both incorporate optical image stabilization, which I found effective but limited when handholding beyond 600mm equivalent.

For wildlife or distant subjects, the SX540's extra zoom can be meaningful, but with the tradeoff of a bulkier body and heavier weight. The SX740 offers a more travel-friendly package with slightly less reach but better overall image stabilization and faster AF to help get the shot.

Video Capabilities: UHD 4K Arrives

Now a critical criterion for many buyers is video functionality, and here the SX740 HS decidedly steps ahead.

• SX540 HS: Max video resolution caps out at Full HD (1920×1080) 60p, recorded in MPEG-4/H.264 formats. No 4K option is available.

• SX740 HS: Supports 4K UHD recording at 30p, also in MP4 (H.264), along with Full HD 60p. This offers much finer detail, enabling cropping and stabilizing in postproduction with less quality loss.

Neither camera offers a microphone or headphone jack, limiting professional audio control. Both have digital zoom during video, but note that digital zoom significantly degrades quality.

In practical use, the SX740’s 4K video capability widens creative opportunities, especially for travel and casual documentary work. Its time-lapse mode adds versatility absent from the SX540.

Battery Life and Connectivity: Staying Power and Sharing Ease

Battery life can impact field shooting plans.

• SX540 HS: Rated for about 205 shots on a single charge per CIPA standards.

• SX740 HS: Improved stamina with approximately 265 shots - suitable for full-day excursions with moderate use.

Both use proprietary battery packs; the SX540 uses model NB-6LH, while the SX740’s exact model is unspecified but presumably optimized for better longevity.

On connectivity:

• SX540 HS: Built-in Wi-Fi and NFC allow wireless image transfer and remote control; no Bluetooth support.

• SX740 HS: Adds Bluetooth Low Energy alongside Wi-Fi/NFC, improving pairing speed and energy efficiency, a real convenience for smartphone tethering.

Both feature USB 2.0 and HDMI output for wired transfers and external monitor use.

Build Quality and Environmental Resistance

Neither camera offers weather sealing, dustproofing, or ruggedness features. Their plastic constructions trade durability for lighter weight and lower cost.

Given their target audiences (travelers, casual photographers, zoom enthusiasts), I advise care in adverse weather or demanding environments. Consider additional protection like sleeves or rain covers if shooting outdoors frequently.
