Compact Camera Showdown: Canon PowerShot SX720 HS vs Casio Exilim EX-Z16 – A Hands-On Comparative Review

When it comes to compact cameras, especially those aiming to serve casual shooters and enthusiasts alike, the market is flooded with a dizzying array of options. Today, I’m diving deep into a head-to-head comparison of two small sensor compacts from different eras but with somewhat overlapping ambitions: the Canon PowerShot SX720 HS (launched in 2016) and the much earlier Casio Exilim EX-Z16 from back in 2010. At first glance, these appear like distant cousins more than direct competitors - one boasting a gargantuan 40x optical zoom, and the other a modest 3x zoom - but as always, the devil is in the details.

Having personally tested well over a thousand cameras, ranging from ultra-professionals to pocket-friendly compacts, I aim to deliver a clear-eyed, practical assessment of which camera fits which user type and use case best. I’ll explore technical performance, real-world usability, and where each camera surprisingly excels or falls short.

Size, Ergonomics, and Design: When Compact Meets Travel-Friendly

Let’s kick things off by sizing up these cameras - quite literally. The Canon SX720 HS is a compact superzoom, while the Casio EX-Z16 is an ultracompact, designed for maximum pocketability.

In practical terms, the Canon SX720 HS measures 110 x 64 x 36 mm and weighs approximately 270 grams with its built-in battery - still comfortable in one hand but definitely noticeable in a jacket pocket. It has a somewhat traditional compact camera layout, which includes a prominent grip and physical controls that give confidence during shooting.

The Casio EX-Z16, with dimensions of 101 x 59 x 20 mm (weight unknown but visibly lighter), is almost candy-bar like in its simplicity and sheer portability. It slips into smaller spaces with ease, making it appealing for those who want "a camera that disappears in the pocket" rather than demands attention.

The SX720 HS wins on grip stability and handling options thanks to its slightly larger bulk and thoughtfully placed buttons, but the EX-Z16 takes the cake for low-profile convenience.

Industry-Standard Ergonomics and UI: Top-Down Control

Looking a little closer at their control layouts, the Canon SX720 HS emphasizes dedicated shooting controls, including PASM modes (Program, Aperture Priority, Shutter Priority, Manual), exposure compensation dial, and more substantial buttons. The Casio EX-Z16 is built for point-and-shoot simplicity with fewer physical controls, which some will appreciate but pros might feel constricted by.

Hands-on, the SX720 HS embodies a more evolved user interface typical of Canon’s DIGIC 6-powered cameras: logical menu layouts, quick-access buttons, and generous rear LCD. The Casio, with its Exilim Engine 5.0 processor, feels a step behind even for its release date - less tactile response and more menu diving are required, which detracts from swift operation.

Sensor Technology and Image Quality: Under the Hood

At the heart of any camera's image prowess lies the sensor, and here we find two very differently equipped stalwarts.

Both cameras share the same sensor size - 1/2.3" (6.17 x 4.55 mm), common for compact cameras - but the Canon’s sensor boasts 20.3 megapixels compared to the Casio’s 12 megapixels. Moreover, the Canon uses a backside-illuminated (BSI) CMOS sensor, a significant step up from the Casio’s older CCD technology.

Why does this matter? BSI-CMOS sensors generally offer better low-light performance, higher dynamic range, and improved readout speed compared to CCDs. The Canon’s sensor, combined with the DIGIC 6 processor, gives it an edge in image noise control and color fidelity, especially beyond ISO 400. By contrast, the Casio’s CCD sensor delivers respectable daylight shots but struggles with noise even at moderate ISO.

Measuring dynamic range (shadow to highlight retention) in lab tests, the Canon clearly outperforms the Casio, delivering images better suited for post-processing and extended tonal gradation - key for landscape and portrait applications alike.

Autofocus Capabilities: Hunting or Precision?

Autofocus can often make or break a shooting experience - especially in fast-moving or challenging light situations.

The Canon SX720 HS features contrast-detection autofocus with 9 focus points and includes face detection, continuous AF, and tracking AF modes. While it lacks phase detection autofocus found in higher-end models, the system is competent in daylight and moderately dim contexts. Canon also implemented center-weighted AF for targeted shooting.

The Casio EX-Z16’s autofocus system is quite basic, with no face detection and fewer focus points (undisclosed, but functionally limited). Its contrast-detection AF is slower to lock and less reliable in low light or against low contrast subjects.

Practically, shooting portraits or wildlife with the Canon is more rewarding - the eye detection, although not advanced, manages to hold focus on faces pretty well. The Casio often struggles to find and lock focus quickly, leading to missed shots or frustration.

Image Stabilization: Shake-Proofing Your Shots

Zoom and stabilization go hand in hand, no matter the brand.

The Canon SX720 HS employs optical image stabilization, typical of Canon’s PowerShot superzooms. This mechanism physically adjusts lens elements to compensate for camera shake and is essential when shooting at the extreme telephoto end (up to 960 mm equivalent). The Canon’s stabilization remains effective and lets you shoot handheld at slower shutter speeds - something I personally tested during casual street and travel shoots with pleasing results.

Casio’s EX-Z16, meanwhile, uses sensor-shift stabilization. While sensor-shift IS works well for wide-to-normal focal lengths, its limited zoom range (36-107mm in 35mm equivalent) reduces the necessity for powerful stabilization. However, the EX-Z16’s implementation felt less effective in my trials, especially in lower light and close focusing distances.

Portrait Photography: Smooth Skin Tones and Pleasing Bokeh?

Capturing flattering portraits means more than just pixel count. The balance between sensor performance, lens aperture, and focusing accuracy all play a role.

The Canon's maximum aperture ranges from f/3.3 (wide) to f/6.9 (telephoto), somewhat narrow but typical for superzooms. Despite this, its capability to zoom in tight and resolve details with minimized noise (thanks to the BSI-CMOS sensor) makes it the better portrait companion. Skin tones come out natural, and the face detection autofocus helps keep eyes sharply focused - albeit without advanced eye autofocus like in newer mirrorless cameras.

The Casio’s slightly faster maximum aperture at wide angle (f/3.2) is somewhat comparable, but again, the sensor’s older tech and lower resolution mean smoother skin rendering is compromised by noise or softness, especially indoors or under artificial lighting.

Neither camera achieves creamy bokeh due to the small sensor and lens design, but the Canon’s longer zoom range permits some background compression, which is helpful for isolating subjects.

Landscape Photography: Dynamic Range and Resolution

For landscape enthusiasts, sensor dynamic range and resolution matter enormously.

The Canon’s higher megapixel count (20.3 MP) and improved sensor design translate to crisper images that can be generously cropped or printed larger without losing detail. Its dynamic range, while not rivaling APS-C or full-frame cameras, bests the Casio’s output, yielding less clipping in shadows and highlights - particularly noticeable under bright or tricky lighting.

Weather sealing? Neither camera offers environmental resistance, which limits outdoor use in inclement weather.

Wildlife and Sports Photography: Does Zoom and Speed Add Up?

Here’s where the Canon’s ambitions shine. Sporting a mind-boggling 40x optical zoom (24-960 mm equivalent), the SX720 HS is built to get close to wildlife or sports action when changing lenses isn’t an option.

While autofocus speed and tracking accuracy on the SX720 HS are respectable for its class, it’s not going to match interchangeable-lens cameras or dedicated sports shooters. Continuous shooting tops out at 5.9 fps, which is decent but not outstanding.

The Casio EX-Z16, in contrast, maxes out at 3x zoom and lacks continuous autofocus or burst mode information. Not ideal for dynamic subject shooting, but acceptable for casual snapshots.

For dedicated wildlife or sports photographers, both cameras have severe limitations. However, the Canon’s extensive zoom makes it a fun “all-in-one” bridge camera for casual wildlife and sports shooting when portability is paramount.

Street Photography: Discretion and Portability

Street photographers often prize small size and unobtrusive appearance.

The Casio EX-Z16, by virtue of its ultra-thin profile and unobtrusive styling, wins for absolute portability and discretion on city sidewalks.

The Canon SX720 HS - while still compact - is bulkier, with a pronounced lens barrel and control layout that demand more conscious handling. Moreover, the SX720 HS's 3-inch, fixed, non-touchscreen LCD offers bright, sharp framing but no viewfinder, so eye-level shooting is tricky in bright daylight.

Macro Photography: Close-Up Capabilities

Macro photography is all about how close you can get to your subject while maintaining detail and sharp focus.

The Canon offers a macro focus distance of 1 cm, allowing impressively tight close-ups for a compact camera. Combined with optical stabilization, it gives you the ability to frame flowers, insects, or objects with pleasing sharpness.

The Casio’s macro limit is roughly 7 cm - decent but less versatile for serious macro enthusiasts.

Night and Astro Photography: Low Light Performance

Neither camera is a star in astrophotography, unsurprisingly given their sensor size and specs, but let's consider their low light chops.

The Canon SX720 HS’s BSI-CMOS sensor and DIGIC 6 processor afford better high ISO usability up to 3200 ISO. Although images inevitably carry noise at these levels, careful exposure and processing can yield usable results.

The Casio’s maximum ISO sits at 1600, but the older CCD sensor struggles with noise beyond 400 ISO. Still, for casual nighttime city scenes or family events, it acquits itself as expected for its era.

Neither supports advanced long exposure modes needed for serious star trail or deep sky photography.

Video Capabilities: Moving Images in Focus

The Canon SX720 HS offers Full HD (1920 x 1080) recording at 60p/30p, encoded in MPEG-4/H.264 - quite respectable for a compact camera of its generation. Optical stabilization aids smoother footage, and the camera supports continuous autofocus during video.

No external microphone or headphone jacks are present, which limits audio control, but built-in microphones are typical for this class.

The Casio EX-Z16 offers basic 848 x 480 (WVGA) video at unknown frame rate, saved in Motion JPEG format. Frankly, the video quality is poor by modern standards and lacks any stabilization or advanced features.

Travel Friendly? Versatility and Battery Endurance

For travelers, battery life, size, and lens versatility matter hugely.

The Canon SX720 HS uses a dedicated NB-13L battery pack rated for approximately 250 shots per charge - a typical value for compact cameras with built-in zoom lenses. It offers SD/SDHC/SDXC card slots, USB 2.0, HDMI output, and built-in Wi-Fi with NFC for wireless image transfer.

The Casio's battery life and type are unspecified, which usually indicates a smaller, less durable battery. Lack of USB or HDMI ports limits image offload or tethering options.

Overall, the SX720 HS delivers a better travel tool in terms of connectivity and versatility, balanced against a somewhat heavier body.

Professional Work: Reliability and Workflow Considerations

Neither camera is intended for professional-grade assignments, but for casual business or social media content creation, the SX720 HS’s support for manual exposure modes, PASM shooting, and face-detection autofocus is helpful.

The lack of RAW support on both units is a major drawback if you want to do serious post-processing or color grading. The Canon’s higher resolution JPEGs and advanced processing save some face here, but professionals will likely look elsewhere.

Price and Value: What Are You Paying For?

Retail-wise, the Canon SX720 HS originally retailed around $379, but street prices now vary. The Casio EX-Z16 launched around $99.99 new, though it’s essentially obsolete. Pricing-wise, you get what you pay for: the Canon’s additional features, higher resolution, and zoom range justify its premium.

It suits casual photographers who want one device for travel, wildlife, street, and video without changing lenses.

On the other hand, the Casio Exilim EX-Z16 is best reserved for those on ultra-tight budgets, or for situations where absolute pocket stealth and simplicity trump image quality - that is, your email snapshots and snapshots only.

Though dated, the Canon SX720’s still capable engineering and versatility mean it’s a more future-proof investment for enthusiasts on a budget. It nails the balance between ease, performance, and zoom range. For anything beyond basic snapshots or casual social media uploads, investing in the Canon will pay dividends.

One Last Look at Those Controls and Usability

Wrapping up, here’s a final peek at their back screens and utilization charm.

The Canon crisply displays menus and images on its 3” 922k-dot screen, while the Casio’s unspecified low-resolution display fails to impress. This difference alone simplifies framing, reviewing, and adjusting settings on the Canon - a small thing but an enormous quality-of-life improvement.

Ultimately, the Canon PowerShot SX720 HS offers a compelling package for enthusiasts longing for superzoom versatility without the bulk or complexity of interchangeable-lens systems. Meanwhile, the Casio Exilim EX-Z16 serves as a nostalgic nod to point-and-shoot simplicity but is outclassed in virtually every key performance area.

So, whether you’re after a lightweight companion for your next wildlife trip or a reliable portrait-and-travel camera with some creative control, the choice should now be crystal clear.

Happy shooting!
