Canon PowerShot SX720 HS vs. Casio Exilim EX-Z90: A Real-World Camera Showdown for Enthusiasts and Pros

As someone who’s spent over 15 years test-driving cameras across genres and shooting conditions, I’m often approached with questions about upgrading compact shooters or investing in travel-friendly zoom cameras. Today, I want to share my detailed hands-on comparison between two compact cameras that highlight quite different design philosophies and technological eras - the Canon PowerShot SX720 HS (2016) and the Casio Exilim EX-Z90 (2009). Both target the casual to enthusiast market, but their capabilities and workflows unmistakably reflect their generation and intended use.

In this article, I’ll guide you through the practical performance, design nuances, and photographic implications of choosing between these two models. Whether you are an enthusiast looking for travel versatility, a casual shooter craving zoom reach, or a professional in need of a pocketable backup, this head-to-head will provide clear insights to match cameras with your shooting style and budget.

First Impressions: Size, Build, and Handling in the Hand

I always start my evaluations by holding the cameras to get a visceral feel for ergonomics and portability - two crucial factors when choosing a camera you’ll carry often.

The Canon SX720 HS sports a compact but slightly chunky hard plastic body measuring 110 x 64 x 36 mm and weighing approximately 270 grams. Its size strikes a balance between pocketability and a comfortable grip, with enough bulk to accommodate a large zoom lens without compromising handling. Meanwhile, the older Casio EX-Z90 is markedly smaller and lighter at 90 x 52 x 19 mm and just 121 grams, fitting snugly into tighter pockets or purses.

In this size-comparison image, you can see the Canon’s substantial grip compared to the ultra-slim Casio, reflecting two different usage goals - versatility vs compactness.

While the Casio is ultra-portable, its slimness also limits direct access controls and ergonomics, making it less comfortable for extended handheld shooting sessions. The Canon’s larger body supports better button mapping, including dedicated zoom and exposure controls, which is a boon when speed and manual input matter.

If you’re prioritizing pocket comfort and ultra-lightweight travel, Casio’s EX-Z90 wins hands-down. But for any kind of manual control and extended handheld use, the Canon SX720’s form factor is noticeably better.

Control Layout and Interface: How Intuitive Is It to Shoot?

Control placement and user interface can make or break a photographic experience - particularly when moments come and go fast.

The Canon SX720 HS employs a classic point-and-shoot top and rear control layout, featuring a respectable physical zoom lever around the shutter and clearly marked mode dial options including manual exposure, aperture priority, and shutter priority modes. The camera's fixed 3-inch, 922k-dot LCD offers a sharp preview for framing, although it is non-touch and fixed (no tilt).

By comparison, the Casio EX-Z90 offers a more basic top layout with fewer external dials and buttons, relying heavily on menus for exposure settings due to the lack of manual exposure modes. Its smaller 2.7-inch, 230k-dot fixed LCD - which, by modern standards, feels dim and less detailed - limits precise framing and review.

Here you can compare the Canon’s robust, photography-centric controls to the Casio’s simpler, more consumer-focused button arrangement.

I found the Canon’s DIGIC 6-powered, swiftly responsive control system vastly more satisfying and practical in the field. The lack of physical exposure compensation on the Casio and the absence of aperture/shutter priority modes make fine-tuning almost impossible in dynamic lighting - frustrating for enthusiasts who like to take creative control beyond auto.

In short, the Canon’s more photographic layout makes it easier and more enjoyable to capture shots quickly with greater control, while the Casio remains firmly an entry-level point-and-shoot.

Sensor Technology and Image Quality: Behind The Scenes

Image quality differences often hinge on sensor generation, size, and processing. Both cameras feature a 1/2.3-inch sensor measuring 6.17 x 4.55 mm, but their node generations and sensor tech differ significantly.

• Canon SX720 HS uses a BSI-CMOS sensor with 20.3 megapixels and Canon’s well-regarded DIGIC 6 image processor. This combination yields respectable dynamic range and good noise control up to ISO 3200. Anti-alias filtering is present, software-based noise reduction is well implemented, and skin tones tend to be natural and warm. The sensor’s backside-illuminated technology helps gather light efficiently relative to older designs.

• Casio EX-Z90 relies on an older CCD sensor with 12 megapixels and a Digic 4 processor. CCD sensors historically excel at color accuracy but struggle more with noise and dynamic range. Max ISO is limited to 1600, and noise becomes problematic over ISO 400 in my tests, resulting in limited low-light usability.

This sensor comparison illustrates how Canon’s newer BSI-CMOS design outperforms Casio’s older CCD in light collection and noise control - key for image quality.

In direct image comparisons, the Canon produces higher resolution photos suitable for 16x20 inch prints without softness, retaining fine detail in leaves and textures. The Casio’s images - though usable for 4x6 prints and social sharing - are less crisp, and the restricted dynamic range means highlights blow out more easily in contrasty outdoor scenes.

For enthusiasts seriously viewing image quality, the Canon’s 20MP sensor and processor will yield more pleasing raw-like JPEGs straight out of camera in most conditions.

Autofocus Performance and Focusing Flexibility

Autofocus speed and accuracy can change a shoot from frustrating to fluid. While neither camera is aimed at pro-grade AF, the Canon SX720 HS leads by a fair margin.

• Canon SX720 HS has a contrast-detection AF system with 9 focus points, including centre-weighted, face detection, and live view AF. It supports continuous and tracking autofocus modes, well suited for moving subjects at moderate speeds such as pets or kids playing.

• Casio EX-Z90 features contrast-detection AF as well but is limited to single AF without face detection or tracking. Its focus mechanism is slower, especially in low contrast or macro scenes.

During my testing when capturing moving subjects like street performers or children, the Canon’s AF locked focus faster and maintained it better than the Casio, which occasionally hunted or missed in tricky light.

Although neither camera can compete with DSLRs or mirrorless hybrids in AF sophistication, Canon’s system offers enough speed and flexibility to make quick snaps less stressful.

Lens Versatility and Zoom Range

When it comes to zoom reach, these two diverge substantially:

• The Canon SX720 HS features a formidable 24-960mm equivalent focal range (40x optical zoom), giving you outrageously wide to super-telephoto capabilities in one compact body. This makes it a dream for travel photographers, wildlife spotters, or anyone looking to cover a wide variety of scenes without changing lenses.

• The Casio EX-Z90’s fixed lens is a modest 35-105mm equivalent (3x zoom), suitable for casual snapshots but limiting if you want to shoot vast landscapes or distant wildlife.

The extreme zoom on the Canon, paired with optical image stabilization, allowed me to capture distant urban skylines or wildlife sharply handheld. With the Casio, I found myself constrained when framing subjects beyond medium telephoto.

Image Stabilization: Handheld Clarity Matters

At these small sensor sizes and long zoom ranges, image stabilization can make or break your results.

• The Canon’s optical image stabilization proved valuable especially at extreme telephoto. I could comfortably handhold shots up to 1/60s at 960mm equivalent focal length, a big practical plus for travel and wildlife.

• The Casio EX-Z90 lacks any form of image stabilization, meaning shots at its maximum 105mm zoom are more prone to blur unless you increase shutter speed or use a tripod.

I tested both indoors and outdoors in similar lighting and consistently noted better sharpness from the Canon at telephoto lengths. If you’re shooting on the go without a tripod, the Canon’s stabilization is a decisive feature.

Screen and Viewfinder Experience

Neither camera includes an optical or electronic viewfinder - this is consistent with their compact, budget-friendly class - so you rely fully on the LCD screens for framing and reviewing.

The Canon’s 3-inch fixed LCD with 922k dots provides a bright, clear viewing experience with excellent color rendition and sharpness. I found it easy to see in most lighting, although direct sunlight required shading.

The Casio’s 2.7-inch, lower resolution 230k dot display feels outdated by modern standards, making precise framing and playback review more challenging. In bright conditions, it washes out considerably.

This image highlights the Canon’s sharper and larger LCD advantage, which improves usability in diverse shooting environments.

For landscape, travel, and street photographers who rely heavily on LCD composition, the Canon’s superior screen is a real usability enhancement.

Battery Life and Storage Convenience

When on location shoots extend, battery endurance and storage flexibility matter greatly.

The Canon SX720 HS uses a Canon NB-13L battery rated for approximately 250 shots per charge. In my real-world travel tests with frequent zooming, reviewing images, and occasional video recording, the battery comfortably lasted a day of moderate shooting.

The Casio EX-Z90 uses an NP-60 battery but manufacturer-rated battery life is not well documented. In practice, I found shorter shooting durations, requiring carrying extra batteries for a full day out.

Both cameras support single SD card slots; the Canon supports SD/SDHC/SDXC, while the Casio accepts SD/MMC/SDHC cards plus internal memory for limited storage.

For longer trips, the Canon’s battery longevity and common battery model offer practical advantages.

Video Capabilities: How Do They Compare?

If you enjoy capturing video clips alongside stills:

• The Canon SX720 HS shoots Full HD 1080p video at 60 or 30 fps in h.264/MPEG-4, with optical image stabilization helping smooth handheld footage. However, it lacks a microphone input or headphone jack, limiting external audio options.

• The Casio EX-Z90’s video maxes out at 720p at 24 fps in Motion JPEG format - an older codec with larger file sizes but less quality than modern compression. No image stabilization is present for video either.

Canon’s video clearly outperforms Casio’s, offering crisper footage and steadier handling suitable for travel vlogging or casual clips.

Real-World Photography Scenarios

Let’s talk about how these cameras hold up specifically across varied photographic genres, drawn from my labs and on-location shoots.

Portraits and People Photography

Canon’s 20MP sensor with face detection and 9 AF points helped nail focus on eyes, producing skin tones that were pleasingly warm and natural under daylight and indoor tungsten lighting. The lens at wide angles (f/3.3) allows subject isolation, but bokeh is limited by sensor size and maximum aperture, as expected. Casio’s limited zoom and slower AF made portrait work less reliable, with harsher skin tones and sometimes sluggish focus acquisition.

Landscapes and Travel

Canon’s wide 24mm equivalent at the wide end is ideal for landscapes. Its improved dynamic range retained highlight and shadow details better in high-contrast skies compared to the Casio’s limited 35mm focal length and more compressed dynamic range. Canon’s weather-sealed body (though minimal) and better battery life lend confidence for travel outings where unpredictability is factored.

Wildlife and Sports

Canon’s zoom and AF tracking help catch moderate action scenes, though burst rate at 5.9 fps and lack of phase detection AF limit pro-speed sports. Casio’s limited zoom and lack of continuous AF make it unsuitable for anything beyond casual snapshots.

Street and Macro Photography

Casio’s slimness and lightness theoretically suited it better for discrete street shooting, but its AF sluggishness and inferior LCD hampered responsiveness. Canon’s superior focus and stable handgrip won out. Macro focus capability was better on Canon down to 1 cm versus Casio’s 10 cm, offering more creative close-up potential.

Night and Astro

Canon’s higher ISO ceiling and cleaner noise handling enable usable shots under dim ambient light, although 1/2.3 sensor limits astrophotography scope. Casio’s struggles with noise at ISO above 400 preclude detailed low-light shooting.

What About Professional Use and Workflow?

For professional or semi-pro photographers considering these cameras as backups or client-friendly devices, important specs include RAW capture and workflow compatibility.

• Neither camera supports RAW image capture, a significant limitation for those requiring precise post-processing latitude.
• Both output JPEGs only, with Canon producing better starting files but limited for heavy editing.
• USB 2.0 connectivity is standard but slow by today’s standards; Canon offers HDMI out for tethered shooting.
• The Canon’s manual modes and exposure compensation capabilities give more creative control, valuable in fast-paced work environments.
