Casio EX-S7 vs Sony TX10

Finding the Sweet Spot: Comparing the Casio EX-S7 and Sony Cyber-shot DSC-TX10 Ultracompact Cameras

When it comes to ultracompact cameras, simplicity and convenience often take center stage - but that doesn't mean you should settle for mediocre image quality or limited features. Today, I’m diving deep into two intriguing models: Casio’s EX-S7, a 2010 release often appreciated for its pocket-friendly profile, and Sony’s 2011 DSC-TX10, known for its rugged design and advanced imaging tech. Both claim to fit snugly into your everyday carry, yet each takes a sharply different approach under the hood.

Having thoroughly tested thousands of cameras, I’m excited to unpack how these two stack up across multiple photography disciplines and everyday use. If you’re weighing an ultracompact choice for your travel bag, street shoots, or even casual macro ventures, this detailed comparison will put the EX-S7 and TX10 under the microscope to reveal their strengths, weaknesses, and which might deserve a spot in your kit.

First Impressions: Size, Feel, and Handling in Hand

One of the very first considerations in an ultracompact is size and ergonomics - how the camera feels to hold and operate. For people like me, who shoot extensively handheld, that tactile experience can make or break the shooting flow.

Looking at the physical dimensions, the Casio EX-S7 measures 97 x 57 x 20 mm and weighs a mere 121 grams, making it notably slim and lightweight. The Sony TX10 is roughly similar in footprint at 96 x 56 x 18 mm but tips the scale slightly heavier at 133 grams. On paper, they’re both impressively pocketable.

But handling goes beyond numbers. The EX-S7’s rectangular body is straightforward and minimalist, lacking an obvious grip but maintaining a clean, streamlined silhouette. The Sony TX10, meanwhile, sports a subtly contoured frame and rubberized edges to enhance grip, particularly useful in wet or cold conditions - something Casio’s offering misses entirely.

Though neither boasts a viewfinder, their large LCDs (more on that shortly) are critical for framing. In real-world shooting, I found the TX10’s design better suited for quick, confident handling - especially for active shooting outdoors or in inclement weather, thanks to its environmental sealing and textured grip.

Command Central: Controls and Interface

Moving from how the cameras feel in your hand to how they put control under your fingers, ergonomics also includes the layout and responsiveness of buttons and menus.

Here, both cameras emphasize simplicity as expected in ultracompacts. The EX-S7 sticks to a bare-bones setup with essential buttons, no customizable controls, and no touch screen for quick adjustments. This minimalism can make menu diving a chore on the small 2.7-inch screen but may appeal if you prefer a distraction-free shooting experience.

The Sony TX10 immediately shines here with its 3-inch touchscreen. This modern interface significantly speeds shooting by allowing touch focus, menu navigation, and image review with taps and swipes. Although touchscreen controls sometimes distract during fast shooting, I appreciated how the TX10 allowed seamless manual focusing in macro mode and easy setting tweaks without button-mashing.

The TX10’s continuously illuminated control ring around the shutter button also reduces fumbling in dim light - an overlooked yet useful feature when time is of the essence.

Seeing is Believing: Screen and Viewfinder Comparison

Without electronic or optical viewfinders, these cameras rely entirely on their rear LCDs for composition.

The EX-S7 sports a modest 2.7-inch fixed LCD with 230k dots resolution. This is serviceable in indoor or shaded environments but can be frustrating under bright sunlight where glare limits visibility. The smaller screen size also restricts image review detail on the spot.

Sony’s TX10, by contrast, comes with a significantly larger 3-inch “XtraFine” LCD boasting 921k dots. The difference in crispness and brightness is immediately noticeable, making outdoor shooting and focus verification more reliable. The touch sensitivity coupled with higher resolution translates into a more intuitive, pleasant user experience overall.

The Heart of the Matter: Sensor Performance and Image Quality

Let’s get technical, because this is where two similarly sized cameras can diverge dramatically. Image quality hinges on sensor technology, resolution, ISO performance, and image processing.

Both cameras feature the same sensor size at 1/2.3” (6.17 x 4.55 mm), a common ultracompact sensor standard. However, Casio’s EX-S7 employs a 12MP CCD sensor, while Sony’s TX10 is equipped with a more advanced 16MP Backside-Illuminated (BSI) CMOS sensor.

The BSI architecture in the TX10 sensor enhances light-gathering efficiency, which translates into better high-ISO performance and dynamic range in real-world shooting. Conversely, the EX-S7’s CCD sensor, while reliable, shows more noise and less flexibility, especially beyond ISO 400.

Resolution-wise, the TX10’s 16MP (4608 x 3456 max image size) gives more detailed files compared to EX-S7’s 12MP (4000 x 3000), which could matter if you plan larger prints or tighter crops.

Unfortunately, neither supports RAW capture - limiting post-processing latitude to JPEGs only. For enthusiasts desiring greater editing control, that’s a downside across both models.

Bringing Images to Life: Sample Photo Quality Verdict

A picture says a thousand words, so I compared real-world shots to evaluate color reproduction, detail, and noise levels.

• Portraits: The EX-S7 renders natural skin tones but tends to over-soften details due to in-camera noise reduction. Background blur (bokeh) is modest, given the 36-107mm equivalent f/3.1-5.6 lens and small sensor. TX10’s slightly wider aperture at the long end (f/4.6 max) is balanced out by superior sensor noise control, delivering sharper images with crisper detail on eyes and hair, although bokeh remains limited due to sensor size.

• Landscape: TX10 pulls ahead with richer dynamic range and sharper details in foliage and skies, thanks to sensor improvements and better image processing. EX-S7’s images lack punch and sometimes suffer from blown highlights.

• Macro: The EX-S7’s macro focus limit is 10 cm, reasonable but overshadowed by TX10’s impressive 1 cm capability - allowing spectacular close-ups. Plus, optical image stabilization on the TX10 is a significant advantage for handheld macro shots, reducing blur from minute shakes.

For critical quality, the Sony TX10 is the clear winner here.

Autofocus and Burst Shooting: Speed and Accuracy Under Pressure

Fast autofocus and burst rates are critical for wildlife, sports, and street photography.

• The EX-S7 offers contrast-detection AF with single-point mode only - no face or multi-area detection, which slows focusing and reduces accuracy on moving subjects.

• Sony TX10 includes a 9-point multi-AF area system with face detection, assisted by contrast-detection AF. While not lightning-fast compared to DSLRs, it reacts promptly for a compact camera.

In burst mode, EX-S7 lacks continuous shooting altogether, whereas TX10 delivers a solid 10fps burst, enabling you to grab decisive moments better.

So, for action orientated shooters, TX10’s technology is far more capable.

Tackling Tough Conditions: Build Quality and Weather Resistance

If you're outdoors a lot, ruggedness matters profoundly.

• Casio EX-S7 doesn’t offer any weather sealing; it is not shockproof, waterproof, dustproof, or freezeproof.

• Sony TX10 stands apart with comprehensive environmental sealing - splash and dustproof construction, freezeproof down to -10°C, and waterproofing to 10 feet (3 meters), making it ideal for adventurous travel and unpredictable conditions.

From mountaintops to beach trips, TX10’s robustness just can’t be beaten at this price point.

Video Capabilities: Moving Beyond Stills

If video is a consideration, Sony’s offering shines clearly.

• EX-S7 records 1280x720p at 30fps in MJPEG format - a legacy codec with large files and limited editing flexibility.
• TX10 shoots Full HD 1080p at 60fps in MPEG-4 and AVCHD with H.264 encoding. Result? Smoother footage, more editing-friendly files, and higher resolution.

Neither camera offers microphone or headphone jacks, so audio capture remains a basic affair.

Battery Life, Storage, and Connectivity: Day-to-Day Practicalities

It’s important to understand usability factors:

• Both cameras use proprietary rechargeable batteries (EX-S7: NP-80; TX10: NP-BN1) with similar life expectancies (~200 shots per charge). I recommend carrying spares.

• Storage-wise, EX-S7 supports SD/SDHC cards; TX10 adds support for SDXC and Sony Memory Stick variants, providing flexibility.

• Connectivity is where Sony TX10 adds value with Eye-Fi card compatibility allowing wireless photo transfer (though no Wi-Fi or Bluetooth).

• Both cameras offer USB 2.0 ports, with TX10 including HDMI output for video playback on TVs.
