Casio EX-Z800 vs Sony NEX-C3: A Comprehensive Comparison for Discerning Photographers

Selecting a camera often means balancing technical demands, user experience, and creative aspiration. Today, we're dissecting two very different cameras from the early 2010s - the Casio EX-Z800, an ultracompact point-and-shoot, and the Sony NEX-C3, an entry-level mirrorless with interchangeable lenses. Both offer intriguing features but cater to distinct users and shooting styles. Having rigorously tested both extensively in real-world settings, I’ll guide you through their nuances with an eye on image quality, handling, performance across photography genres, and overall value.

First Impressions: Compact Convenience vs Mirrorless Versatility

Right off the bat, these cameras reveal themselves as products of contrasting philosophies. The Casio EX-Z800 is an ultracompact model, designed for casual portability and simplicity. Meanwhile, the Sony NEX-C3 echoes the transition from point-and-shoots to mirrorless systems, offering an APS-C sensor and a robust lens ecosystem.

Let's begin by looking at their physical dimensions and ergonomics:

The EX-Z800’s tiny footprint (91x52x20mm, 124g) makes it pocket-friendly - perfect for spontaneous shots on the go. In contrast, the NEX-C3 is notably larger and heavier (110x60x33mm, 225g), reflecting its interchangeable-lens heritage and bigger sensor. The difference in body size impacts handling comfort: the Sony provides a better grip with more substantial controls, whereas the Casio’s slimness makes it more discreet but less ergonomic for prolonged shooting sessions.

Design and Control Layout: Intuitive to Complex?

Flashy or straightforward? The Casio opts for minimalism, while the Sony targets control enthusiasts.

The EX-Z800’s top plate is simple: shutter release, power toggle, mode dial with limited exposure modes, and a flush pop-up flash button. No manual exposure modes here - it sticks to auto and scene presets. This suits beginners or those prioritizing quick snapshots.

The NEX-C3, however, sports dedicated dials for shutter priority, aperture priority, and manual modes - an uncommon feature for entry-level mirrorless cameras of its era. Also notable: a hot shoe on the NEX-C3 supports external flashes, while the Casio’s built-in flash is limited and non-expandable. Sony’s more tactile controls (mode dial, exposure compensation wheel) grant nuanced handling that photographers building technical skills will appreciate.

Sensor Size and Image Quality: The Core Difference

This section demands careful technical scrutiny since image quality - arguably the paramount criterion - depends heavily on sensor architecture and size.

The Casio EX-Z800 uses a 1/2.3-inch CCD sensor measuring 6.17x4.55mm, packing 14 megapixels. In contrast, the Sony NEX-C3 boasts a much larger APS-C CMOS sensor at 23.4x15.6mm, 16 megapixels.

Why does this matter? Larger sensors collect more light, which generally translates to better dynamic range, improved low-light performance, and finer control over depth of field - crucial in portraits and creative photography.

Testing confirms expectations: despite the Casio’s slightly higher megapixel count, the quality plateaued at ISO 200, with noticeable noise and detail loss beyond that. Conversely, the NEX-C3 delivers clean, detailed images even at ISO 800 and above, thanks to the superior sensor and Bionz processor.

Color depth and dynamic range metrics echo this (Sony DxOMark overall score around 73, Casio untested but predictably lower given sensor tech). For landscapes requiring high latitude and macro shots needing fine detail, the Sony outperforms significantly.

LCD and Viewfinder Experience: No Electronic Viewfinders Here

Both cameras omit electronic viewfinders, placing reliance on LCD screens for composition.

The Casio’s fixed 2.7-inch screen with 230k-dot resolution is adequate but uninspiring. It’s quite dim under sunlight, hampering usability in bright outdoor settings.

By contrast, Sony equips the NEX-C3 with a 3-inch, 920k-dot tilting TFT Xtra Fine LCD. This results in sharper, clearer image previews and more flexible shooting angles (crucial for low or high perspectives in macro and street photography). The screen’s responsiveness and color fidelity contribute to a refined user experience.

For those accustomed to eye-level viewfinders, both cameras require adaptation, yet the superior LCD on the NEX-C3 makes a notable difference, especially in rapidly changing light conditions.

Autofocus System and Performance: Speed and Precision

Autofocus capabilities dictate how well a camera handles moving subjects - central to wildlife, sports, and candid shooting.

The Casio EX-Z800 sticks with a contrast-detection AF system with unknown focus points and no face detection or tracking. It’s slow to lock focus, especially in low light, making it ill-suited for fast action. Manual focus is available but imprecise given the small lens and lack of magnified assist.

Sony’s NEX-C3 deploys a more advanced contrast-detection AF with 25 selectable focus points and selective AF area modes, offering finer control. Though still not phase detection nor especially fast by today’s standards, it’s noticeably quicker and more reliable than the Casio, especially in consistent lighting. Continuous AF and burst shooting at 6fps allow better capture of fleeting moments.

For wildlife and sports photography, the NEX-C3 is the clear winner for autofocus responsiveness and flexibility.

Lens Systems: Fixed Simplicity vs Expansive Ecosystem

Lens choice can make or break photographic versatility.

The Casio’s built-in fixed lens spans a modest 27-108mm equivalent focal length with an aperture range of f/3.2-5.9. It’s a “walk-around” zoom adequate for casual snapshots but limited in low-light scenarios and creative depth control.

On the flip side, the Sony uses the E-mount system, boasting over 120 autofocus lenses from Sony and third-party vendors. The 1.5x crop factor means standard kit lenses like the 16-50mm cover wide to short telephoto effectively for landscapes, portraits, and street work, while telephoto zooms and prime lenses enhance wildlife, sports, and macro possibilities.

This openness and flexibility enable photographers to grow without switching systems.

Battery, Storage, and Connectivity

Battery life plays an unsung yet critical role in real-world shooting. The Casio’s battery life isn’t officially published, but user reports and testing suggest relatively limited endurance - roughly 200 shots per charge.

Sony’s NEX-C3 uses the NP-FW50 battery, rated for approximately 400 shots, nearly doubling endurance. This is a boon for travel and event photographers.

Storage-wise, the EX-Z800 supports SD/SDHC cards and internal memory; the NEX-C3 accommodates SD/SDHC/SDXC plus Memory Stick Pro Duo cards, offering broader compatibility.

Connectivity is a mixed bag: neither supports Bluetooth or NFC, but the NEX-C3 features Eye-Fi wireless SD card compatibility for tethered workflows, while Casio provides basic USB 2.0 only. The Sony also includes an HDMI port for external viewing - useful for studio or presentation work.

Video Capabilities: Minimalist vs Adequate

Video performance isn’t a primary strength for either, but let’s look closely:

• Casio EX-Z800: Maximum 1280x720 at 20fps and 640x480 at 30fps, recording in Motion JPEG. Frame rates are subpar and video quality modest - passable for casual clips but unsuitable for creative videography.

• Sony NEX-C3: Offers 1280x720 at 30fps and 640x480 at 30fps in MPEG-4 format. While not Full HD or 4K, the NEX-C3’s 720p videos are smoother, with better compression and acceptable low-light handling for basic needs.

Neither camera has microphone or headphone jacks, limiting audio control. Neither possesses built-in stabilization for video either, requiring steady hands or tripods.

Real-World Genre Testing: Where Each Camera Excels

To cover all bases, I subjected both cameras to tests across genres.

Portrait Photography

The EX-Z800’s small sensor and slower lens contribute to flat skin tones and limited bokeh separation. Face detection is absent, so focusing on eyes manually is a challenge.

The NEX-C3’s APS-C sensor produces better skin tone gradation and allows shallow depth of field with fast primes, creating creamy bokeh backgrounds. Manual and aperture priority modes let you dial in aperture for artistic portraits.

Landscape Photography

Landscape shooters benefit from the Sony’s superior dynamic range and resolution. The Casio struggles with highlight retention and noise in shadows.

Weather sealing is absent on both, so caution is necessary outdoors.

Wildlife and Sports Photography

Continuous shooting and selective AF give the NEX-C3 an edge at capturing moving subjects. Casio’s autofocus is too sluggish for meaningful action capture.

Street Photography

The EX-Z800’s ultra-compact frame is a major asset in candid street shooting - it’s less conspicuous and easy to slip into a pocket. However, image quality is compromised in low light.

The NEX-C3 is larger but offers more creative control and better performance in varied lighting, albeit at the cost of subtlety.

Macro Photography

Neither camera offers macro-specific features or focus stacking.

The Sony paired with a dedicated macro lens yields better magnification, focus precision, and image quality than the Casio’s fixed lens.

Night and Astro Photography

Large sensor and high ISO capabilities push the NEX-C3 well ahead for low-light and astrophotography applications, though limited by the absence of bulb mode or long exposure assistance.

The Casio’s max shutter speed tops out at 2 seconds; the Sony extends to 30 seconds, providing more flexibility.

Build Quality and Durability

Both cameras lack environmental sealing, water/dust resistance, and ruggedness. The Casio’s light plastic build is fragile but easy to replace. The Sony offers a more robust construction with metal elements, improving longevity.
