Canon ELPH 510 HS vs Canon SX730 HS: In-Depth Superzoom Compact Camera Comparison for Enthusiasts and Professionals

When exploring compact superzoom cameras, Canon’s lineup offers intriguing options that balance pocketability with versatile zoom ranges. The Canon ELPH 510 HS, also known as the IXUS 1100 HS outside the Americas, debuted in 2012 as an entry-level compact with a respectable 12x zoom. Five years later, Canon introduced the PowerShot SX730 HS, stepping up the game with a whopping 40x zoom and modern features. Both cameras cater to photographers seeking convenience merged with zoom flexibility but approach that goal quite differently.

Having logged extensive hands-on testing hours with both models, I’ll dissect these cameras on everything from sensor tech and image quality to autofocus performance and real-world usability. This exhaustive comparison is designed for enthusiasts and professionals who want to understand their practical strengths and limitations - beyond just the spec sheet. Let’s dive into how these two Canon superzooms stack up for various photography genres, technical prowess, and shooting scenarios.

First Impressions on Size, Build, and Handling

Right out of the gate, it's clear these cameras are designed with portability in mind, but they don’t feel identical in the hand. The Canon ELPH 510 HS is a slim, lightweight compact measuring just 99 x 59 x 22 mm and weighing 206g. Its sleek design and minimalist controls reflect the early 2010s trends aimed at casual point-and-shooters.

In contrast, the PowerShot SX730 HS is significantly larger and heavier at 110 x 64 x 40 mm and 300g - largely due to the physically longer 40x zoom lens and added feature set. While still pocketable in larger coat pockets or bags, it’s noticeably bulkier and more substantial.

Ergonomically, the SX730 HS offers more pronounced grip contours and a more robust feel. Meanwhile, the ELPH 510 HS’s ultra-slim profile means you often rely more on touchscreen controls and less on physical buttons. The SX730’s retention of dedicated manual controls, exposure compensation dial, and tilting screen caters better to enthusiasts who want tactile feedback and flexible framing options.

Personally, when testing these cameras over extended use, I found the SX730 HS's heft gave me more confidence during handheld shooting, especially with long focal lengths - reducing fatigue compared to the lighter but slimmer ELPH 510 HS.

Design Philosophy and Control Layout

Taking a detailed look at the top and back designs illustrates Canon’s evolving approach between these two models.

The ELPH 510 HS keeps the top plate clean with a simple shutter button and power toggle - minimalist and approachable for casual users. The rear is dominated by a fixed 3.2-inch PureColor II TFT LCD screen with 461k-dot resolution. Controls are touch-centric with minimal buttons, which can sometimes complicate fast adjustments or navigating menus under pressure.

The SX730 HS trades the larger screen resolution of the ELPH’s display for a 3.0-inch, 922k-dot tilting LCD. While smaller, the SX730's screen articulates upward, enabling low-angle and selfie-friendly shooting. Physical buttons and dials for manual exposure, menus, and zoom make it far more responsive during active shooting.

Overall, Canon shifted from a casual snapshot-style interface towards a more enthusiast-oriented control scheme, underscoring the SX730 HS’s design to support more deliberate photo creation. The lack of touchscreen on the SX730 HS initially feels like a downside but is offset by improved tactile control precision.

Sensor and Image Quality: The Heart of the Comparison

Both cameras use a 1/2.3-inch BSI-CMOS sensor measuring 6.17x4.55mm, a sensor size common in compact superzooms. However, the SX730 HS pushes the resolution envelope with a 20.3-megapixel sensor, compared to the 12.1-megapixel sensor in the ELPH 510 HS. Both employ an anti-aliasing filter to reduce moiré.

From a technical standpoint, the higher resolution sensor in the SX730 HS offers theoretically better detail capture and cropping flexibility, which is a boon for landscape and wildlife photographers demanding finer resolution. Canon’s DIGIC 6 processing engine in the SX730 HS also improves noise control and dynamic range relative to the older DIGIC 4 processor (or earlier) found in the ELPH 510 HS.

In practice, the ELPH 510 HS produces clean, pleasing images in good light, but noise and detail degradation become evident beyond ISO 400, limiting usable ISO range to 100-400 for quality handheld shots. The SX730 HS extends usable ISO range up to 800 or even 1600 with better noise management, courtesy of the higher-res sensor and updated processor.

Color reproduction for both models is typical Canon: generally accurate and natural skin tones, though the SX730 HS delivers richer, more nuanced colors, particularly in outdoor scenes with complex lighting.

Without raw support on either model, photographers must accept some post-processing limitations - these cameras focus on straight-out-of-camera JPEGs. The SX730 HS’s slightly better in-camera processing algorithms help reclaim shadow detail and control highlight roll-off more effectively - an asset for landscape and portrait shooters seeking more dynamic range.

Versatile Zoom Lenses: Reach vs Aperture Trade-offs

One cannot discuss these cameras without addressing their zoom capabilities - the core appeal of small sensor superzooms.

• Canon ELPH 510 HS: 28-336mm equivalent (12x zoom), aperture f/3.4-5.9
• Canon SX730 HS: 24-960mm equivalent (40x zoom), aperture f/3.3-6.9

The 40x zoom of the SX730 HS is truly impressive, extending from moderately wide-angle framing (24mm) up to a super-telephoto 960mm reach. This versatility unlocks possibilities from casual landscapes to full-frame wildlife and sports telephoto shots - all in one package.

However, apertures on the SX730 HS narrow substantially - dropping to f/6.9 at full zoom - which challenges low-light telephoto shooting. The ELPH 510 HS’s modest 12x zoom sports somewhat faster apertures at the long end (f/5.9 vs f/6.9), aiding indoor or dim-light telephoto scenarios.

For macro photography, both cameras focus down to 1 cm (approx. 0.4 inches) from the lens - excellent for close-up shots of flowers and small objects - with optical image stabilization (OIS) helping reduce blur from hand movements.

Bear in mind, longer reach on the SX730 HS magnifies camera shake effects. While OIS does an admirable job, a tripod or monopod is recommended for sharp results beyond 400mm equivalent focal length.

Autofocus Systems: Speed and Accuracy Under Various Conditions

Neither camera has phase-detection autofocus - a technology usually reserved for DSLRs and mirrorless models - but both rely on contrast-detection AF, including face detection.

• The ELPH 510 HS supports touch-based AF, continuous and single autofocus modes, and simple tracking.
• The SX730 HS improves AF speed somewhat with DIGIC 6 processing, offers manual focus override, and has more sophisticated AF area modes.

I evaluated autofocus performance across several scenarios:

• Portraits: Both cameras lock onto faces reliably indoors and outdoors. Slightly faster AF acquisition from the SX730 aids capturing fleeting expressions.
• Wildlife and Sports: Tracking fast-moving subjects reveals the limitations of contrast-detection AF, especially in low contrast or low light. The SX730 HS manages burst rates near 6 fps - almost double the ELPH’s 3 fps - helping frame action sequences, although buffer capacity and AF tracking capabilities constrain prolonged shooting.
• Macro: Both models excel at focusing close, but the SX730 HS’s manual focus ring allows precise adjustment, vital for shallow-depth-of-field macros.

Overall, neither camera replaces professional autofocus systems, but the SX730 HS’s refined AF and burst mode make it more capable for dynamic shooting.

Screen and User Interface: Viewing and Playback Experience

Both cameras lack electronic viewfinders (EVFs), which puts more emphasis on rear LCD usability for framing and reviewing images.

The ELPH 510 HS offers a larger 3.2-inch fixed touchscreen with modest resolution. The touchscreen functionality simplifies menus and quick settings access - important for beginners or casual shooters. However, fixed position LCD limits shooting flexibility and harder outdoor viewing.

By contrast, the SX730 HS’s 3.0-inch, higher-resolution LCD tilts upward roughly 180 degrees, a boon for selfie and low-angle shots. The lack of touchscreen is somewhat mitigated by the more thoughtful physical controls and the more detailed display.

In bright sunlight, both screens struggle with reflections. The SX730 HS’s anti-reflective coating and slightly better brightness give it an edge.

Image Stabilization, Shutter, and Flash Capabilities

Optical image stabilization (OIS) is crucial in small-sensor zoom cameras, especially with long reach focal lengths.

Both the ELPH 510 HS and SX730 HS sport optical stabilization systems that proved effective in reducing camera shake during handheld shooting, including macro and telephoto captures. However, the SX730 HS's newer processor allows slightly improved stabilization responsiveness.

The shutter speed ranges are similar, with both cameras offering 15 seconds to around 1/3200-1/4000 second maximum shutter speed. Neither offers electronic shutter modes or silent shutter options.

Integrated flashes on both cameras provide basic fill-in light, with the SX730 HS's slightly longer range flash (4.00m vs 3.1m), and modes like slow synchro that help balance ambient light in portraits.

Video Recording Capabilities: A Modest Upgrade

Videographers won’t find 4K or advanced video features here, but both cameras deliver good 1080p performance.

• ELPH 510 HS: Full HD 1920 x 1080 at 24 fps; slower frame rate and older codec (H.264).
• SX730 HS: Full HD 1080p at 60 fps, a notable advantage for smoother motion capture; also records in MPEG-4 and H.264.

Neither camera has external microphone input, limiting audio quality control, and both lack headphone jacks. Image stabilization helps smooth handheld video footage, but with longer telephoto zoom engaged on the SX730 HS, some jitter noticeable remains.

Battery Life, Storage, and Connectivity

Battery life is a key practical consideration for travel and extended shoots.

• The ELPH 510 HS lacks official rated battery life but uses NB-9L batteries; in my testing, battery capacity lasted roughly 200-250 shots per charge.
• The SX730 HS specifies 250 shots CIPA rating, which aligns with my experience, though this decreases when frequently using the zoom and Wi-Fi.

Storage options for both cameras use SD/SDHC/SDXC cards with one slot, standard for compacts in their class.

Wireless connectivity is where the SX730 HS outshines the ELPH. It features built-in Wi-Fi, Bluetooth, and NFC support - providing seamless image transfer and remote shooting capabilities through Canon’s Camera Connect app. The ELPH relies on Eye-Fi card compatibility for wireless transfer, an outdated solution requiring specialized SD cards.
