Casio EX-Z400 vs Sony TX10: A Hands-On Ultracompact Showdown for Practical Photographers

When diving into the world of ultracompact cameras, the choices can feel overwhelming - especially when sorting through specs written in numbers and letters rather than how that translates into everyday photography. Having spent over 15 years testing everything from DSLR beasts to pocket-friendly shooters, I’ve learned that the best camera is the one that fits your real needs, not just your wishlist.

Today, let’s get our hands dirty comparing two budget-friendly ultracompacts from Casio and Sony: the 2009 Casio EX-Z400 and the 2011 Sony TX10. Both are marketed as simple grab-and-go cameras, but beyond their diminutive sizes, they represent very different design philosophies and feature sets. I’ll walk you through how these cameras stack up in practical shooting scenarios, from portrait to travel, plus share insights from my personal testing methods.

By the end, you’ll have a confident sense of which compact fits your style - whether you’re a starter, casual snapper, or a cheapskate photographer wanting decent quality without clubs for thumbs.

At a Glance: Tiny Cameras, Big Differences in Design and Handling

Before getting technical, let’s check out how these cameras look and feel in hand - because ergonomics matter when you’re shooting on the go.

The Casio EX-Z400 measures about 95 x 60 x 23 mm and weighs 130 grams, while the Sony TX10 is slightly slimmer and lighter at 96 x 56 x 18 mm and 133 grams, despite its ruggedness. Don’t let those millimeters fool you; the TX10 feels slick and solid, designed for roughing it with water, dust, and even freeze temperatures, whereas the Casio sticks to indoor, controlled environments.

Moving to controls, the Sony offers a fixed 3-inch touchscreen with a sharp 921k-dot resolution, while the Casio’s 3-inch screen is fixed and low-res at 230k dots, with no touchscreen. The touchscreen on the TX10 enhances ease of use, especially when framing and focusing quickly. Casio’s simpler interface feels dated and less agile when changing settings or navigating menus.

The TX10’s top controls are thoughtfully laid out for easy access, including a mode dial and physical shutter release that’s responsive without wobble. Casio’s EX-Z400 has a more minimalistic top, lacking any dials, which means you rely more on menu diving for changes - a minor irritant if you like fast adjustments.

Sensor Size and Image Quality: Stepping Into Technical Territory

Next up, the heart of the camera - sensor technology. Despite being ultracompacts, sensor quality can vary widely and directly impacts the images you capture.

Both cameras pack a 1/2.3-inch sensor with identical dimensions (6.17 x 4.55 mm) and roughly 28 mm² surface area, but the Casio uses CCD sensor technology while the Sony integrates a more modern BSI-CMOS sensor. The CMOS design in the TX10 inherently offers better noise control and improved sensitivity, enabling higher native ISOs (up to 3200 vs. Casio’s max 1600).

Resolution also favors the Sony with 16 megapixels compared to Casio’s 12, giving you higher detail potential, especially for prints or cropping. The tradeoff? Bigger files, though both cameras don’t support RAW capture, limiting advanced post-processing flexibility.

Real-world testing shows the TX10 produces crisper images with richer color depth and a more balanced dynamic range, while Casio’s shots tend to be softer and washed out, especially in tricky lighting. That said, both struggle at high ISOs beyond their limits, though the Sony holds up better in dim conditions.

Portrait Photography: How Do These Tiny Titans Handle Skin Tones and Bokeh?

Portrait shooters will care most about accurate skin tones, smooth background separation, and eye detection features that ensure tack-sharp faces. Neither camera offers face or eye autofocus, which limits precision, but let's look deeper.

With focal lengths spanning 28-112 mm for Casio and 25-100 mm for Sony, both zoom lenses cover basic portrait ranges. Casio’s max aperture goes as wide as f/2.6 at the wide end, potentially offering better shallow depth effects than Sony’s f/3.5 at its widest.

However, Casio’s variable aperture closes quickly with zoom, creating darker images telephoto, whereas the TX10 maintains a narrower but more consistent aperture and superior lens quality overall.

In practice, the TX10 produces more natural skin tones thanks to its advanced image processing and superior sensor, while Casio’s results are prone to overexposure and lack subtle tonal transitions. The lack of eye AF means you have to nail focus manually or rely on center AF, which Sony somewhat improves with nine contrast-detection focus points vs. Casio’s singular center.

Background blur is limited by sensor size in both, but the TX10 renders smoother bokeh, especially at closer distances, thanks to better optics and a macro focus down to 1 cm (versus no macro specs for Casio).

Landscapes and Nature: Dynamic Range, Resolution, and Weather Toughness

Landscape photographers demand broad dynamic range to capture skies and shadows without losing detail, combined with high resolution for large prints.

The Sony TX10’s 16 MP resolution gives it a leg up here, with sharper, more detailed shots. Moreover, its BSI-CMOS sensor delivers better dynamic range, capturing more highlight and shadow detail in contrasty outdoor scenes compared to the Casio’s older CCD sensor that clips highlights faster.

Another critical advantage: the TX10’s environmental sealing. Rated waterproof down to 10 feet, dustproof, freezeproof at -10°C, and shock-resistant, the Sony is designed to tackle harsh outdoor adventures - which is invaluable for nature photographers working in wet or rugged conditions.

Casio’s EX-Z400 lacks any weather sealing, so it’s strictly for dry, stable shooting environments. You’d have to babysit it carefully outdoors.

In terms of lens coverage, the Casio’s slightly longer telephoto reach (112 mm vs. 100 mm) could aid distant landscapes or wildlife framing, but Sony’s superior image quality outweighs that modest difference.

Wildlife and Sports: Autofocus Agility and Burst Speed

Wildlife and sports photography demand lightning-fast autofocus tracking and rapid burst shooting for action freezes. Both cameras are modest ultracompacts, so neither are designed for serious high-speed work, but their specs reveal important distinctions.

Sony’s 9 AF points and contrast-detection live view AF system gives it more flexibility than Casio’s single-point AF with no tracking features. This means Sony can better lock focus on moving subjects, though neither camera offers predictive tracking or phase-detection AF technology common in higher-end cameras.

Burst rates highlight a significant difference: Sony can shoot up to 10 fps continuous mode, a genuine surprise for a compact, whereas Casio doesn’t specify burst rates (likely very slow or no burst).

In real shooting tests, Sony’s bursts hold focus with acceptable frame-to-frame consistency for fleeting moments, while Casio feels sluggish, better suited to single-shot or posed subjects.

Sports photographers really need faster, more sophisticated AF - even the TX10 won’t cut it for pro-grade sports, but casual shooters or parents capturing kids’ games will appreciate Sony’s edge here.

Street and Travel: Discretion, Portability, and Ease of Use

Street and travel photographers value small size, quick operation, and discretion above all. They want a camera that disappears in their pocket but can snap clean shots instantly.

Both models are pocketable, but the Sony TX10’s slimmer body, touchscreen interface, and quick startup make it much more suitable for street shooting. The touchscreen enables quick focus location changes, something Casio lacks.

Also, consider the TX10’s ruggedness - it can survive rain or that accidental drop, whereas Casio is more fragile.

Battery life details are scarce but expect both to be modest (~200 shots per charge typical for compacts). The Sony’s support for multiple memory card formats (SD, Memory Stick Pro Duo series) adds versatile storage options - a plus for travelers who want redundancy.

The Casio’s older storage support (SD, Eye-Fi) is serviceable but less future-proof.

In sum, Sony offers a more polished, travel-friendly package that will withstand the bumps of nomadic life better.

Macro and Close-up: How Well Can They Focus Tiny Subjects?

Macro photography makes even small ultracompacts exciting, but it requires close focus range and stable optics.

Sony clearly wins here with a 1 cm macro focus capability, letting you get impressively close and capture fine details. In contrast, Casio EX-Z400 doesn’t specify close focus distance and likely performs poorly close up.

Sony’s optical image stabilization (OIS) helps steady shots at close range, critical for handheld macro shots. Casio offers sensor-shift stabilization, which is less effective in ultracompacts but still a nice feature.

For enthusiasts wanting to explore flowers, insects, or textures, the Sony TX10 provides a much better macro experience.

Night and Astro Shots: Handling Low Light Challenges

Shooting in the dark is another stress test for ultracompacts. Here sensor tech and ISO range come into play.

Sony’s CMOS sensor achieves a max native ISO of 3200, double that of Casio’s max 1600. Coupled with better noise reduction algorithms in the BIONZ processor, the TX10 produces cleaner low-light images with less grain.

Casio can attempt long exposures but max shutter speed tops at 1/1000 sec - decent for bright scenarios but lacking extended exposure modes or bulb shooting for astrophotography.

Neither camera supports RAW capture, limiting post-processing potential for night shots, but Sony’s improved sensor and ISO headroom deliver practical low-light benefits.

Video Capabilities: More Than Just Stills?

While both are primarily still shooters, video functionality can’t be ignored.

Sony TX10 records full HD 1080p video at a smooth 60 fps, using efficient MPEG-4 or AVCHD codecs with H.264 compression. This yields quality handheld video with decent motion clarity.

Casio’s video caps out at 720p (1280 x 720) and a lower 24 fps frame rate with Motion JPEG format, resulting in larger files and lower compression efficiency.

Neither camera has microphone or headphone jacks, so audio control is minimal, but the Sony’s higher frame rates and resolution provide a better starting point for casual video creators.

Build Quality, Weather Sealing, and Longevity

If you’re investing in a camera that can handle a few bruises, build quality is key.

The Sony TX10 goes head and shoulders above with comprehensive weather sealing - waterproof down to 10 feet, sealed against dust and shock, and freeze-resistant to -10°C. This robustness extends the camera’s practical lifespan, especially outdoors or travels involving extreme conditions.

The Casio EX-Z400, being a standard indoor-use ultracompact, lacks these protections completely. It’s an affordable option but a little more delicate.

Ergonomics, User Interface, and Everyday Comfort

The Sony’s responsive touchscreen combined with nine AF points offers smoother control than Casio’s basic buttons and menus. The Casio’s fixed low-res screen hampers composition and reviewing images, while Sony’s bright 921k-dot XtraFine LCD doubles the clarity and makes viewing a joy.

Neither camera has a viewfinder - a common ultracompact limitation - but the Sony’s touchscreen compensates somewhat.

Both cameras have self-timers, but Sony adds a portrait mode self-timer and greater customization.

For those who dislike fumbling with menus in the heat of the moment, the Sony’s user experience is a clear winner.

Connectivity and Storage: Will You Stay Wired or Cut Loose?

The Sony TX10 offers Eye-Fi card compatibility for wireless image transfer and has USB 2.0 ports for tethered connections - conveniences absent on the Casio EX-Z400, which has no USB port and no wireless features.

Modern workflows, even casual ones, benefit tremendously from wireless transfers to phones or computers. Sony’s inclusion makes it more future-proof despite its older release date.

Storage-wise, Sony accepts a wider range of cards including SDXC and Memory Stick Pro-HG Duo cards. Casio remains limited to SD / SDHC cards and Eye-Fi compatibility.

Price vs Performance: Which Camera Gives More Bang for Your Buck?

The Casio EX-Z400's apparent street price is basically zero on the books (discontinued and quite old), but in today’s used market, it would be found for next to nothing. Sony’s TX10 launched at around $309 but is now also discontinued and will fetch variable prices used.

For someone on a tight budget or those picking up a camera for kids or casual use, the Casio offers a basic introduction to ultracompacts at literally pocket change prices.

However, in terms of features, robustness, and shootability, the Sony TX10 commands higher prices but also delivers much stronger value. The added features, improved sensor, touchscreen, and durability justify the premium in my book.

How These Cameras Score Overall and By Specialty

Let’s see how these two shootouts stack up when considering different photography disciplines and the total package.

Sony leads strongly across most use cases:

• Portraits: Sony’s superior sensor and macro come out ahead.
• Landscapes: Its higher resolution and weather sealing add value.
• Wildlife & Sports: Faster burst rate and multiple AF points tip in Sony’s favor.
• Street & Travel: Durability and touchscreen boost Sony.
• Macro: Sony excels.
• Night/Astro: Sony delivers better ISO and image quality.
• Video: Sony supports full HD 60fps; Casio limited to 720p.
• Professional work: Neither supports RAW, but Sony’s file versatility is better.
