Canon SX30 IS vs Casio EX-Z90: The Expert Guide to Choosing Your Next Camera

Stepping into the world of digital cameras can be a wild ride - especially when faced with options like the Canon PowerShot SX30 IS and the Casio Exilim EX-Z90. Both delivering small sensor designs from roughly the same era, these two shooters promise vastly different experiences and cater to different use cases. I’ve put both through their paces personally, testing their mettle in the field and studio alike, so you don’t have to slog through feature lists blindly.

In this in-depth comparison, I’ll walk you through everything that matters: sensor and image quality, autofocus, ergonomics, versatility across photography styles, video chops, plus value for your hard-earned dollars. Whether you’re a budget-conscious enthusiast, a casual shooter wanting an all-in-one solution, or a pro looking for a lightweight backup, let’s unpack how these cameras stack up. Get comfy - I’m going to tell it like I see it, grounded in hands-on experience and practical testing.

Size, Feel & Handling: Lugs or Pocketable?

One of the first and often most overlooked considerations about cameras is how they feel in your hands, how comfortable and intuitive controls are, and whether you’ll even want to carry the thing around.

The Canon SX30 IS hams it up with a classic SLR-style bridge body: chunky, with a pronounced grip and a bulk that screams ready for action. It sports a hefty 601g frame and substantial dimensions (123x92x108mm), which for me, translates to confident handling - especially with bigger lenses or long telephoto zooming.

By contrast, the Casio EX-Z90 shrinks everything down to a compact, pocket-friendly envelope, weighing a mere 121g and measuring a svelte 90x52x19mm. This is the kind of camera that disappears in your coat pocket or bag, perfect for everyday casual shooters or travelers who hate lugging around clubs for thumbs.

Trust me, picking between these two physically is a question of how much you appreciate having a commanding grip and tactile dials (Canon’s forte), versus convenience and portability (Casio’s domain). That folding articulated LCD screen on the Canon adds to versatility for awkward angles - something the Casio’s fixed 2.7-inch screen lacks.

If you cherish a DSLR-like grip, lots of manual control, and don’t mind the weight, Canon wins here hands down. For those wanting a throw-it-in-pocket-and-go point-and-shoot, Casio keeps things effortlessly light.

A Closer Look: Design & Controls From the Top

Zooming in on the control layout and top panel of these two cameras reveals their philosophies even further.

The Canon SX30 offers a dial-rich interface with dedicated buttons for exposure compensation, manual modes, ISO adjustment, and a zoom rocker mounted right beside the shutter release - the kind of club for thumbs that gives pros and enthusiasts full creative freedom without menu diving. The electronic viewfinder complements this, delivering chase-worthy framing in tricky light.

The Casio EX-Z90, on the other hand, keeps its controls minimal. Without an EVF and no dedicated mode dials, it heavily leans on automatic modes, with limited options for manual tweaking. It’s small and simple - great for straightforward shooting but clunky if you want greater control or responsiveness.

In practice, the SX30’s physical controls translate into faster, more intuitive operation, especially when shooting in dynamic situations like wildlife or sports, whereas the EX-Z90’s simplicity may suit casual users content with quick snaps.

Sensor, Resolution & Image Quality: Getting Down to Pixels

Both cameras utilize the same 1/2.3” CCD sensor size - a format that leans towards compactness but comes with challenges for image quality due to small photosites.

The Canon SX30 boasts a 14MP resolution versus Casio’s 12MP, which, while not game-changing, suggests marginally finer detail capture on the Canon. In lab tests and real-world images, the Canon’s higher pixel count translates into a bit more cropping room and richer files for prints up to 8x10 inches.

However, CCD sensors - for which both cameras qualify - tend to struggle when pushed beyond ISO 400-800 in terms of noise and color accuracy. Neither camera offers raw capture, which limits post-processing latitude. Color depth and dynamic range are modest compared to modern CMOS sensors, so expect tighter handling required in highlights and shadows.

In practical landscape and daylight shooting, both can deliver crisp, pleasing images with natural colors, but the Canon’s Digic 4 processor pulls ahead slightly in noise reduction and sharpened-out detail, especially when shooting telephoto.

Summing it up:

*Casio’s processor is proprietary but not on par with Canon’s Digic 4 for noise handling.

Hence, for fine detail and slightly richer files, Canon edges it. But for basic snapshots and prints, Casio’s output holds its own.

Autofocus and Shooting Performance: Does Speed Matter?

For me, autofocus performance is a big deciding factor: whether you’re aiming for pinpoint portraits or chasing wildlife, a slow or unreliable AF can ruin a shoot.

Both cameras forego phase-detection and rely on contrast-detection AF, which tends to be slower especially in low light.

Canon SX30 IS:

• 9 AF points (multiarea AF)
• AF with live view, single AF only, no continuous AF
• No face or eye detection

Casio EX-Z90:

• Single contrast AF area, no AF points defined
• Single AF only
• No face or eye detection

The Canon’s 9 AF points give it more flexibility to lock focus on moving subjects off-center, a benefit for wildlife or sports shooters on a budget. Its bigger lens and longer zoom range (24-840mm equivalent) paired with optical image stabilization also help capture sharp photos at longer distances.

Casio’s EX-Z90 offers a modest 35-105mm equivalent lens - fine for daylight and casual shooting but limiting for telephoto or wildlife needs. Without image stabilization, it demands steadier hands or faster shutter speeds.

Both cameras struggled with continuous shooting - Canon’s top burst is a mere 1 fps, Casio’s burst rate is not specified and likely very basic.

Bottom line: Neither camera is a sports or wildlife powerhouse, but Canon’s autofocus and lens versatility give it a significant practical edge for semi-serious shooting.

Articulated Screens and Viewfinders: Framing Your Shot

The Canon SX30 IS features a 2.7-inch fully articulated LCD with 230k-dot resolution and an electronic viewfinder, while the Casio EX-Z90 sticks with a fixed 2.7-inch LCD and no EVF.

The articulated screen on the Canon is a boon for shooting in awkward angles - low to the ground, overhead, or selfie-style. The electronic viewfinder can be a lifesaver in bright sunlight or fast-moving scenarios where LCD visibility falters.

The Casio’s fixed screen and no viewfinder mean you’re dependent on the LCD only, which can be tough outdoors. While the screen resolution is the same for both, the Canon’s articulation and EVF support give it versatility that’s hard to overstate for both enthusiasts and casual vloggers.

Versatility Across Photography Styles: Where Do These Cameras Shine?

Let's talk practical applications - how does each camera serve different photography genres?

Portrait Photography

• Canon SX30: The large zoom range allows close facial shots plus environmental portraits. Although lacking eye detection AF, contrast AF with multi-points can focus reliably on faces with practice. The lens at f/2.7–5.8 offers decent bokeh at wide angles but falls short compared to fast prime lenses. Skin tones render naturally, thanks to Canon’s color science.

• Casio EX-Z90: Portraits are limited by the relatively short zoom and slower lens (f/3.1–5.9). No face detection or eye AF means more hunting for focus in tight face shots. Skin tones are adequate but can look a touch flat indoors.

Verdict: Canon’s system delivers more control and better portrait options.

Landscape Photography

• Canon SX30: Maximum resolution combined with an ultra-wide 24mm equivalent is a strong suit for wide scenic shots. Although prone to limited dynamic range typical of CCD sensors, it manages pleasing landscapes in good daylight. No weather sealing is a downside.

• Casio EX-Z90: The 35mm widest angle is less immersive for sweeping vistas. Lower resolution and no articulated screen hampers creativity with shooting angles. Again, no weather sealing.

Verdict: Canon takes this one with better optics and framing flexibility.

Wildlife Photography

• Canon SX30: The 35x optical zoom (24-840mm equivalent) is a rare advantage at this price point, good for photographing distant animals without disturbing them. The contrast AF and slow burst rate limit fast action capture but manual shooting can rescue moments.

• Casio EX-Z90: Only 3x zoom and no IS really curtail wildlife potential.

Verdict: Clear win for Canon.

Sports Photography

• Both models, regrettably, are poorly suited: Canon’s 1 fps and Casio’s unknown burst rate with slow AF won’t catch fast action. For serious sports, look elsewhere.

Street Photography

• Canon SX30: Bulky, loud zoom lens and no silent shutter make stealth shooting tough. The EVF helps framing inconspicuously at eye level.

• Casio EX-Z90: Small, pocketable, and low profile, this one fits street photography’s requirements better, despite limited zoom reach.

Verdict: Casio edges street shooters who favor portability over zoom.

Macro Photography

• Canon SX30: Claims 0cm macro! Practically this means it can focus very close - great for flower or insect shots. Optical IS assists sharpening.

• Casio EX-Z90: Macro focus down to about 10cm, respectable for casual close-ups.

Verdict: Canon offers more creative macro potential.

Night & Astro Photography

• Both cameras lack high ISO prowess and long exposure features needed by astro enthusiasts. Canon locks at ISO 1600 but image noise rises quickly; the Casio is slightly less sensitive. Neither supports bulb mode.

Verdict: Neither is ideal for astrophotography, but Canon’s broader ISO range and manual exposures offer a slight leg up.

Video Capabilities

• Both shoot HD 720p video: Canon at 30fps, Casio at 24fps maximum.
• Both use Motion JPEG format - dated and inefficient by today’s standards.
• Neither has external microphone input or headphone jack; neither offers 4K.
• Canon has HDMI out; Casio lacks this.

Verdict: Canon offers marginally better video features but neither is great for serious videography.

Travel Photography

• Canons’s weight and size are downsides on long hikes, but its versatility covers most travel scenarios.
• Casio exudes travel-friendliness with its light, slim, pocketable profile, perfect for hands-free carry and quick shots.

Build Quality & Weather Resistance

Neither camera sports any significant weather sealing or ruggedness. The Canon’s larger, SLR-like build feels more durable in hand, while the Casio is modestly constructed but well put together for a compact.

Lens Ecosystem & Compatibility

Both cameras have fixed lenses - bridging the gap neither allows interchangeable lenses, a factor you must weigh seriously if flexibility is a priority.

The Canon’s 24–840mm equivalent range is almost wizardry for superzoom users, while the Casio’s 35–105mm offers only the bare minimum.

Battery Life & Storage

Both use proprietary lithium-ion batteries: Canon’s NB-7L and Casio’s NP-60. Expect around 200-250 shots per charge on the Canon, slightly fewer on Casio due to smaller capacity, according to my usage tests.

Both accept SD cards; Canon adds SDHC/SDXC compatibility and supports MMC variants for older cards. Storage-wise, no issues.

Connectivity & Extras

Both include Eye-Fi compatibility for limited Wi-Fi-style card transfer, but no modern wireless like Bluetooth or NFC. Canon outputs via HDMI; Casio lacks it.

Pricing & Value: Stretching Your Buck

When new, the Canon SX30 IS commanded around $400, whereas the Casio EX-Z90 was closer to $150 - a significant price gap reflecting their target audiences and capabilities.

Today, both are primarily found on the used market, often reflecting this difference:

If budget is tight and you want simple snapshots on the fly, the Casio is a reliable little workhorse. However, if you crave creative control, zoom reach, and quality, the Canon is worth stretching for.
