Canon PowerShot SX530 HS vs SX730 HS: A Hands-On Exploration of Two Small-Sensor Superzooms

Choosing the right superzoom camera in today’s crowded market can be as tricky as nailing a perfect candid shot in busy street photography - fleeting and endlessly subjective. Canon’s PowerShot SX series has long catered to those craving big reach in a compact package. Here, I take you through a deep-dive comparison between the Canon SX530 HS (announced in early 2015) and its slightly newer sibling, the SX730 HS (introduced in 2017). My aim? To unlock the real-world performance story hiding behind their spec sheets and marketing glitz, based on countless hours testing camera ergonomics, image quality, and usability across diverse shooting scenarios.

If you’re a photography enthusiast or a professional eyeing a reliable superzoom for travel, wildlife, or versatility without the bulk of interchangeable lens systems - this is the place to start. Grab a cuppa and let’s compare what these two compact titans deliver, from sensor tech to button clicks, zoom reach to burst speed.

Getting to Know the Contenders: Physical Design and Handling

Before plunging into pixellated nitty-gritty, size and handling set the stage for any shooting experience. The Canon SX530 HS adopts a classic bridge camera approach, with an SLR-like body that aims to marry a big grip and stability with sub-DSLR heft. The SX730 HS, by contrast, trims down into a more genuinely compact form factor - closer to a pocketable superzoom - trading some bulk for easy portability.

The SX530 HS tips the scales at about 442 grams, with dimensions of 120 x 82 x 92 mm. It feels robust and comfortably chunkier in hand, thanks to its larger grip and pronounced control dials. This camera is suited for those who want a solid, almost DSLR-esque feel without the interchangeable lens complications.

The SX730 HS weighs just 300 grams and measures a neat 110 x 64 x 40 mm. That’s almost half the volume of the SX530 HS - quite a difference! If you juggle backpacks stuffed with gear or want a camera always on hand for street, travel, or casual snaps, the SX730 HS’s svelte profile feels less intrusive and easier to stash.

One trade-off with this slimness is the ergonomics. The SX530 HS offers a heftier grip and more accessible manual controls - crucial for traditionalists who prefer turning dials over menu diving. The SX730 HS feels more minimalist and less “camera-like,” highlighting that it’s designed for users who prioritize convenience over extensive tactile feedback.

The top plates tell a parallel story. Let’s zoom in on the control layout.

Here, the SX530 HS sports a more traditional camera-top layout, including a dedicated mode dial and more visible buttons arranged ergonomically around the shutter. The SX730 HS trims those back, offering fewer physical dials and more reliance on menu navigation - it feels more streamlined, but some users will miss the tactile control spontaneity.

Sensor and Image Quality: Tiny Sensors with Big Responsibilities

Both cameras utilize a 1/2.3-inch BSI-CMOS sensor measuring 6.17 x 4.55 mm - small by DSLR or mirrorless standards, but common in superzoom compacts to keep costs and lens designs manageable.

The SX530 HS comes with 16 megapixels, while the SX730 HS edges ahead to 20.3 megapixels - a bump on paper that suggests crisper images and more cropping flexibility. However, my own tests (involving controlled studio charts and real-world shooting) revealed that this resolution difference doesn't directly translate to significantly sharper images under typical shooting conditions - small sensors run into the same diffraction and noise ceilings regardless of megapixel count.

Both lack RAW support - no surprising news, but disappointing for those aiming to squeeze every ounce of post-processing flexibility. JPEG output is the only choice, so maintaining exposure accuracy and white balance freshness is critical.

In terms of dynamic range and ISO performance, the DIGIC 6 processor in the SX730 HS brings modest improvements to noise handling and color fidelity, especially beyond ISO 800, where the older DIGIC 4+ in the SX530 begins to show more luminance noise smudging fine detail.

Low-light landscapes or twilight portraits benefit from this advance, though expectations must remain realistic. Neither camera can rival APS-C or full-frame sensors here, but the SX730 HS's incremental image processing advancements matter when you’re pushing limits.

The Lens Showdown: Superzoom Capabilities for the Reach-Hungry

Superzooms are all about lens versatility, and these two models both cover impressive focal length ranges.

• Canon SX530 HS: 24-1200mm equivalent (50x zoom), aperture F3.4-6.5
• Canon SX730 HS: 24-960mm equivalent (40x zoom), aperture F3.3-6.9

The SX530 HS offers the longer focal reach by a significant margin. This 1200mm equivalent telephoto is a powerful tool for distant wildlife, faraway sports shots, or when climbing atop a mountain isn’t on the day’s agenda. The maximum aperture range is similar - neither lens is particularly ‘fast,’ reflecting the inevitable trade-off of extreme zoom in a compact body.

The SX730 HS’s 960mm telephoto is shorter but still formidable. Its lens also delivers a slightly brighter aperture on the wide end. Practically speaking, aside from absolute maximum reach, the SX730 HS benefits from a slightly more modern optical formula and improved image stabilization - which shows when you handhold at long zoom settings.

This brings us to macro capabilities: the SX730 HS’s macro focusing starts at a notably close 1cm, allowing for interesting near-subject details. The SX530 HS, in contrast, does not specify a macro focus range and tends to struggle closer than a few centimeters, delivering less snappy close-up results.

Focusing and Speed: Tracking Your Subject Without Breaking a Sweat

Autofocus is where the rubber often meets the road - especially for active or wildlife shooting.

Both cameras employ a hybrid autofocus system combining contrast-detection with limited phase detection on the SX530 HS (9 focus points) and contrast-only on the SX730 HS (point count unspecified by Canon, but thousand tests show it utilizes traditional contrast detection).

• The SX730 HS delivers a significantly faster burst shooting speed (5.9 fps vs 1.6 fps on the SX530 HS). This advantage translates to more confidence when tracking action - whether it’s jumping squirrels or a football game.

• Eye detection autofocus and animal eye AF are absent on both models. For portrait shooters wanting precision on eyes, the face detection helps but isn’t as robust as modern mirrorless systems.

• Continuous autofocus during video live view performs better on the SX730 HS given its newer processor, resulting in smoother focus pulls and tracking.

Viewing and Composing: Screens and Viewfinders

Both cameras forgo electronic viewfinders - a disappointment for some, but fairly standard in this segment.

• The SX530 HS opts for a fixed 3-inch LCD panel with 461k dots, adequate but showing its age.
• The SX730 HS boasts a brighter, tilting 3-inch 922k dot screen - crisper and more versatile, especially for vlogging or shooting at challenging angles.

In bright sunlight, the SX730 HS’s better resolution and tilt mechanism make framing easier, while the SX530 HS’s fixed screen sometimes necessitates awkward hand positions or squinting.

Neither has a touchscreen, so menu navigation relies on buttons, which are better spaced on the SX530 HS due to its larger body.

Sample Shots and Real-World Images

Technical specs are fascinating, but what ultimately impresses (or disappoints) is the output. Below is a gallery comparing images from both cameras under controlled and real-life conditions:

• Portraits: SX730 HS’s higher megapixel count edges ahead in detail, but skin tones and color rendition remain similar - both produce pleasing tones albeit with a slight softness typical of small sensors. Bokeh is modest on both, as aperture and sensor size limit shallow depth.

• Landscape: Dynamic range shows slight improvements in the SX730 HS, with modest recovery of shadows and highlights. Resolution bump helps when printing or cropping.

• Wildlife/sports: SX530 HS’s longer reach allows tighter framing from the same spot, but slower AF and burst rate mean more missed moments versus SX730 HS.

• Macro: SX730 HS shines with sharp close focus and better stabilization here.

• Night: Both are noisy at ISO above 800, but SX730 HS’s DIGIC 6 processor tames noise better - a subtle but useful advantage for astro enthusiasts dabbling in star trails or cityscapes.

Durability, Battery Life, and Storage

Both cameras lack weather sealing or ruggedized construction, limiting outdoor use in adverse conditions.

Battery life favors the SX730 HS at around 250 shots per charge, slightly better than the SX530 HS’s 210 shots - helpful for travel or day-long excursions.

Both rely on SD/SDHC/SDXC storage cards, with a single slot. Neither offers dual card slots, which again reflects their consumer-friendly positioning rather than professional robustness.

Connectivity and Extras

The SX730 HS more fully embraces wireless convenience. It supports Wi-Fi with Bluetooth and NFC pairing for seamless smartphone transfers - ideal for social media sharing on the go.

The SX530 HS offers basic built-in Wi-Fi but lacks Bluetooth or NFC - an understandable omission in 2015 but somewhat dated now.

Both cameras record Full HD video at 1080p, but the SX730 HS extends codecs to 60fps with higher bitrate MP4, promising smoother footage. Neither supports 4K, external microphones, or headphone jacks - limitations that will chafe serious videographers.

Overall Performance Scores and Genre-Specific Ratings
