Canon SX730 HS vs. Olympus SZ-15: Which Superzoom Compact Suits You Best?

Choosing between two compact superzoom cameras like the Canon PowerShot SX730 HS and the Olympus SZ-15 can feel a bit like trying to pick your favorite lens – both offer solid capabilities but vary enough in key areas to sway purchasing decisions. With over 15 years of hands-on camera testing behind me, I’ve put these two small sensor superzoom compacts through the wringer, evaluating everything from image quality to ergonomics to real-world shooting scenarios. This deep dive aims to arm you with practical insights - not just spec sheet recitation - helping you find the best match for your photographic passions and budget.

Let’s jump in.

Size, Handling, and Controls: How Do They Feel in Your Hands?

Before any technicalities, the physical experience of handling a camera shapes much about your shooting comfort and speed. While both cameras are categorized as compact superzooms, the subtle differences in size, weight, and design ergonomics can influence your day-to-day use.

The Canon SX730 HS measures about 110 × 64 × 40 mm, weighing in at 300 grams. The Olympus SZ-15 is slightly slimmer at 108 x 70 x 40 mm but lighter at 250 grams. If pocketability and carrying light matters to you - say, for travel or street photography - the Olympus offers a slight edge here. The Canon feels a touch more substantial, which for me translates to better grip and stability, particularly important during longer handheld shooting sessions at extended focal lengths.

Looking at the control layout from the top, the Canon SX730 HS showcases a clean design with clearly marked dials and buttons that make switching shooting modes and adjusting exposure straightforward even on the fly.

By contrast, the Olympus SZ-15 adopts a more minimalist approach, which might appeal if you prefer fewer distractions but could feel limiting if you want quick access to manual controls. Neither has a viewfinder - a common compromise for compact superzooms - meaning you’ll rely mainly on the rear LCD for framing.

The SX730's tilting 3-inch screen with a resolution of 922k dots outshines the SZ-15's fixed 3-inch LCD at 460k dots, presenting a notably crisper viewing experience:

For my workflow, the sharper, articulating screen on the Canon isn’t just a luxury - it’s a productivity booster, especially when shooting low or high angles, or capturing videos.

Sensor Technology and Image Quality: The Heart of the Matter

Both cameras share the 1/2.3" sensor size (6.17 x 4.55 mm) often found in superzoom compacts, but the underlying sensor technology and resolution tell a story about image quality potential.

The Canon SX730 HS uses a 20.3-megapixel backside-illuminated CMOS sensor coupled with the DIGIC 6 image processor - a combination that favors better light sensitivity and noise control compared to older or CCD sensors. The Olympus SZ-15, meanwhile, packs a 16-megapixel CCD sensor, reflecting its 2013 heritage.

Practically, this translates to cleaner images at higher ISOs on the Canon, enabling usable shots in dimmer conditions without excessive grain. Given both cameras max out at ISO 3200, the SX730 HS’s sensor and processor advantage manifests in lower noise and improved dynamic range. That said, neither are going to challenge APS-C or full-frame cameras for ultimate image quality, but around 20 MP on a BSI CMOS in a 2017 budget superzoom is pretty respectable.

Zoom Performance and Optics: Getting Close and Staying Sharp

Superzoom cameras hinge on their long focal lengths. The Canon boasts a 24-960mm equivalent zoom (40x optical zoom) compared to the Olympus’s 23-483mm (21x zoom).

This ultra-telephoto reach with the Canon opens doors for shooting wildlife or distant subjects without lugging heavy telephoto lenses - quite a feat from a compact camera!

Both cameras feature optical image stabilization to counteract shake, which is critical for long zoom focal lengths, but Canon’s system benefits from incremental improvements over four years newer tech, delivering steadier shots handheld.

Macro performance tips in Canon’s favor as well, with a minimum focusing distance of 1 cm versus Olympus’s 5 cm - if close-up flower shots or tiny details excite you, Canon nudges ahead.

Autofocus Systems Put to the Test: Speed, Accuracy, and Flexibility

I ran autofocus tests in typical daylight and dimmer indoor scenarios to compare speed and reliability.

• Canon SX730 HS: Employs contrast-detection AF with face detection and continuous AF modes. AF speed is snappy for a compact, rarely hunting in daylight and maintaining lock well in video mode.

• Olympus SZ-15: Uses contrast-detection based AF with face detection and multi-area options but lacks continuous autofocus - resulting in slower and more hesitant focusing behavior, especially in lower light.

The Canon’s ability to track moving subjects more smoothly (though still limited compared to enthusiast mirrorless or DSLRs) makes it better suited to casual wildlife and sports shooting. Olympus’s AF performance is more basic and suited for static subjects or casual snapshots.

Image Stabilization and Burst Shooting: Catch the Moment or Freeze Action?

When shooting wildlife or sports, frame rate and stabilization are crucial.

• Canon SX730 HS offers continuous shooting up to 5.9 fps and optical IS which feels effective up to moderate telephoto reach.

• Olympus SZ-15 claims a faster physical rate of 10 fps continuous shooting but lacks continuous AF, so most shots outside static subjects risk being out of focus.

In practical terms, Canon’s balanced system will yield more keepers during action sequences despite a slightly lower burst rate.

Video Capabilities: More Than Just Stills

Both cameras record Full HD 1080p video, but how do they compare overall?

Canon’s smoother 60p frame rate offers more fluid motion capture - ideal for casual video work or travel vlogging. Meanwhile, Olympus includes high-frame-rate slow motion modes but at very low resolutions, limiting their creative use.

For anyone serious about video on a budget, Canon’s codec efficiency and quality edge offer a better starting point.

Battery Life and Connectivity: Staying Powered and Linked

Battery endurance and modern connectivity features can make or break convenience.

The Canon SX730 HS promises roughly 250 shots per charge - modest by today’s standards, but still typical for compact superzooms. It also features Bluetooth and NFC for quick pairing with smartphones and a micro-HDMI port for external viewing.

The Olympus SZ-15 battery life is unspecified in its specs (model SLB-10A), and it lacks Bluetooth or NFC, though it does incorporate GPS - fun for geotagging photos if you travel a lot.

USB 2.0 is supported by both, which is slow for large transfers but sufficient for casual use.

Image Samples: Real-World Quality to Guide Your Eye

Nothing beats looking at results. I captured identical scenes in controlled outdoor light with both cameras. Notice that while both produce decent JPEGs straight out of camera, the Canon’s images show more detail, crisper edges, and punchier colors with less noise.

You can see from these sample crops how the Canon handles texture better (skin, foliage) and maintains highlight details, whereas the Olympus yields flatter, softer results prone to early noise at base ISO.

How Do They Score Overall? A Performance Snapshot

From my comprehensive battery of lab and field tests, here’s how these cameras measure up across key performance criteria:

Canon SX730 HS leads comfortably in image quality, autofocus, video features, and usability. Olympus SZ-15 matches only in battery life (variable), portability, and offers unique features like embedded GPS and slow-motion video.

Genre-Specific Strengths: What Fits Your Photography Style?

To zoom in (pun intended) on specific photographic disciplines:

• Portraits: Canon’s higher resolution and better color rendering deliver pleasing skin tones and softer bokeh at longer focal lengths. Olympus’s brighter max aperture at the wide end helps in low-lit indoor portraits but less so overall.

• Landscape: Olympus SZ-15 performs adequately but Canon’s improved dynamic range and higher megapixels win here.

• Wildlife: Canon’s extensive zoom (40x vs. 21x), faster autofocus, and optical IS make it a better casual wildlife companion.

• Sports: Canon leads, due to continuous AF and decent burst performance.

• Street: Olympus’s lighter weight may matter if discretion and portability top your list, though Canon’s superior image quality is hard to ignore.

• Macro: Canon’s 1-cm focusing beats the Olympus’s 5-cm minimum distance hands down for extreme close-ups.

• Night/Astro: Neither excels here due to sensor size and high ISO limitations, but Canon’s BSI CMOS sensor copes slightly better.

• Video: Canon clearly outperforms Olympus with 60p capture and superior codec.

• Travel: Canon’s versatility, screen articulation, and connectivity edge make it the more flexible traveler’s camera.

• Professional Work: Neither camera is truly pro-level, but if limited to their class, Canon’s image quality and feature set could support casual pro workflows in pinch situations.

Final Thoughts: Who Should Buy the Canon SX730 HS? And Who the Olympus SZ-15?

After hands-on evaluation and cross-discipline testing, here’s my summing up:

Canon SX730 HS: The More Capable Performant Superzoom for Enthusiasts

Ideal if you want:

• Greater zoom reach to 960mm for wildlife or distant subjects
• Sharper 20 MP image quality and better low-light performance
• Responsive autofocus with face detection and tracking
• Articulating screen enabling flexible composition angles
• Full HD 60p video capture
• Compact but comfortable ergonomics for longer sessions
• Modern connectivity (Bluetooth, NFC) for instant sharing

Canonical shortcomings: Limited battery life (250 shots), no raw support, no external mic, and no viewfinder may deter serious shooters. Also, max aperture starting at f/3.3 limits bokeh effect somewhat in portraits.

Olympus SZ-15: Budget-Friendly Compact with Basic Features and Ease of Use

Better suited for:

• Casual users prioritizing light weight and simplicity
• Those who like built-in GPS for travel logging
• Users who want a bright wide-angle aperture (f/2.8) for snapshots and indoor shots
• High-speed burst shooting (10 fps) for static subject action
• Very affordable entry into a superzoom fixed-lens camera

But be aware: the CCD sensor limits image quality, slower AF and smaller zoom range constrict use cases, no continuous AF or high-frame-rate video, and fixed LCD reduce flexibility.

Closing Note: Your Next Superzoom’s Role in Your Gear Bag

Neither the Canon PowerShot SX730 HS nor the Olympus SZ-15 replace an enthusiast’s interchangeable-lens camera. Their smaller sensors and fixed optics limit ultimate image quality and pro-level control. Yet, for enthusiasts craving super-telephoto reach and compact convenience, the Canon SX730 HS ticks more boxes, especially for diverse shooting needs that include wildlife, travel, and casual video.

If budget constraints or GPS tagging specifically appeal - and you favor compact size and simple operation - the Olympus offers a competent package worth considering.
