Casio EX-ZR400 vs Sony RX100 VA

Casio EX-ZR400 vs Sony RX100 VA: A Compact Clash for the Enthusiast's Pocket

When it comes to compact cameras, size often dictates convenience, but image quality and handling separate the casual from the serious enthusiast. Today, I’m diving deep into a head-to-head between two intriguing contenders from different eras and market segments: the 2013 Casio EX-ZR400 and the 2018 Sony RX100 VA. They both promise pocketable versatility, but from my extensive experience testing hundreds of compacts, these two deliver quite different experiences - and reveal much about how small sensor cameras evolved over the last decade.

Join me as I break down their design, performance, and real-world usability across all major photography genres, from portraits to astro shots. By the end, you’ll be equipped to decide which one, if either, deserves space in your camera bag.

First Impressions: When Size Matters - And When It Doesn’t

In the world of compact zoomers, physical ergonomics shape everything from comfort during long shoots to steadiness in hand-held conditions. The Casio EX-ZR400 and the Sony RX100 VA are both designed to stow away easily, but their handling philosophies diverge sharply.

The Casio (105 x 59 x 29mm, 205g) looks like your classic slim bridge camera - light and unobtrusive, perfect for casual outings. The RX100 VA (102 x 58 x 41mm, 299g) is slightly thicker and heavier, but that extra heft translates to a more solid grip and an impression of robust construction. The Sony also features a more substantial lens barrel, hinting at the larger sensor and higher performance under the hood.

From my hands-on trials, the Sony’s increased thickness didn’t make it feel bulky; it actually enhanced one-handed shooting stability, especially when using faster shutter speeds or in low light. Meanwhile, Casio’s slender build was ideal for quick snaps and pocket carry, but it sacrificed some grip comfort and steadiness, especially with extended zoom use.

A Tale of Two User Interfaces: Controls and Screens

Look beyond the raw specs, and usability nuances come into sharp relief. The camera’s interface often is make-or-break for sustained creative enjoyment.

On the top plate, the EX-ZR400 keeps it minimalistic - few buttons and a simple control dial, which is fine if you’re happy with point-and-shoot ease and occasional manual tweaking. The Sony RX100 VA, on the other hand, is button-heavy, sporting a dedicated exposure compensation dial, a custom function button, and a ring around the lens - delightfully tactile for those who prefer direct access to settings without diving into menus.

Moving to their back screens, Casio employs a fixed, 3-inch 461k-dot super clear TFT panel - adequate but lacking flair. The RX100 VA impresses with a 3-inch 1229k-dot tilting LCD, dramatically improving framing versatility and outdoor visibility.

Notably, the Sony includes a bright electronic viewfinder (EVF) with 2359k dots resolution, 0.59x magnification, and full 100% coverage - critical for precise composition in bright sunlight or when you want to conserve battery. The Casio lacks any viewfinder, making it less suited for tricky lighting or more deliberate framing.

From the perspective of daily creative control, the RX100 VA’s refined interface and EVF presence make it infinitely more usable in diverse shooting environments - something I’ve experienced first-hand during prolonged photo walks.

Under the Hood: Sensor Size and Image Quality

Now, to the heart of every camera debate: the sensor. It’s where the rubber truly meets the road in image fidelity.

The Casio EX-ZR400 sports a tiny 1/2.3-inch BSI-CMOS sensor (6.17 x 4.55mm, 28.07 mm²), delivering 16 megapixels maximum (4608 x 3456 px). This design targets a superzoom segment with a 24–300mm (equiv., 12.5x optical zoom) lens, impressive on paper for one compact body.

Sony ups the ante with a 1-inch BSI-CMOS sensor, physically much larger (13.2 x 8.8mm, 116.16 mm²) and sporting 20 megapixels (5472 x 3648 px). This difference means notably better light gathering, higher dynamic range, and cleaner image outputs at elevated ISOs.

From extensive sensor testing, including DXO Mark references and practical shooting, the RX100 VA’s sensor manifests as clear winner in detail resolution and noise control. The Casio is more prone to noise creeping above ISO 800 and shows modest dynamic range; shadows and highlights compress noticeably under contrasty light.

For landscape shooters, the Sony’s expanded resolution and enhanced dynamic range deliver richer tonal gradations and finer detail capture. Casual day-to-day users might find the Casio sufficient, but in challenging lighting or print-sized work, it doesn’t keep pace.

Autofocus: Snappiness, Accuracy, and Tracking

Autofocus is where a camera’s personality really rises or falls, especially if you photograph moving subjects.

Both cameras rely on contrast-detection autofocus. The Casio EX-ZR400 offers a simplistic system with center-weighted focus area but supports AF tracking in stills mode - somewhat helpful but prone to hunting outdoors.

The Sony RX100 VA employs a hybrid AF system utilizing 315 phase-detect points with complementary contrast detection - a considerable upgrade.

My real-world testing across wildlife and street photography reveals stark differences. The RX100 VA locks focus swiftly and tracks subjects smoothly in continuous autofocus (AF-C) mode, even when zoomed in at 70mm equivalent. The Casio struggles with autofocus sluggishness and less consistent subject tracking once moving elements enter the frame.

This makes the RX100 VA better suited for action, sports, and wildlife shooting scenarios - with reliable eye detection support for portraits improving sharpness on faces. The Casio, while fine for static scenes, can frustrate burst shooting or erratic subjects.

Zoom Range and Lens Aperture: Reach vs. Speed

Let’s talk glass. The Casio’s advantage is its expansive 24-300mm equivalent zoom - a 12.5x optical multiplier - versatile for everything from wide-angle group shots to distant subjects. Aperture ranges F3.0 at wide end to F5.9 telephoto are typical of zoom compacts but not exactly “fast.”

Conversely, Sony’s RX100 VA lens covers a shorter 24-70mm equivalent range (2.9x), but boasts much brighter maximum apertures (F1.8 – F2.8). This opens creative doors - with shallower depth of field for portrait bokeh effect, better low light performance, and improved subject separation.

For portrait shooters craving creamy backgrounds, the RX100 VA’s faster optics excel - especially combined with larger sensor and face-detection autofocus. The Casio’s superzoom is great for travel and wildlife where reach is king, but will yield flatter, noisier images in dim settings.

Portrait Photography: Skin Tones and Bokeh Battle

Portraiture demands subtle tonal reproduction and controlled background blur to isolate subjects elegantly.

Thanks to a combination of its sizeable 1” sensor, brighter lens, and intelligent face-detection AF, the Sony RX100 VA captures skin tones with a pleasing natural look - fleshtones are true without oversaturation or muting. Its background separation is authentic and smooth, lending a professional air for headshots or candid images.

The Casio EX-ZR400, with its smaller sensor and narrower aperture, produces flatter skin tones and less convincing bokeh. Backgrounds simply don’t melt away well, and portraits feel more snapshot than studio-like. Not a killer flaw, but for serious portrait lovers, the RX100 VA stands head and shoulders above.

Landscapes: Dynamic Range and Resolution in the Field

Landscape photography puts a premium on wide dynamic range to hold detail from shadowed forests to bright skies, combined with ample resolution to capture fine textures.

Sony’s larger sensor and better optics shine here. The RX100 VA reliably captures intricate detail in foliage, rocks, and water reflection, plus it preserves sky gradations with minimal clipping. While it lacks weather sealing, its sensor capability and 20MP resolution deliver images that stand up well for large prints or cropping - a real boon outdoors.

The Casio can handle ordinary daylight landscapes with decent sharpness but often shows pronounced noise in darker shadow areas due to its smaller sensor and limited dynamic range. The max aperture narrowing to F5.9 at telephoto restricts creative framing slightly and complicates handheld twilight shots.

For landscape pros or serious hobbyists, RX100 VA’s superior image quality outweighs Casio’s zoom advantage.

Wildlife and Sports: Speed, Burst, and Focus Tracking

If your photographic passions lean toward action - be it feathery forest dwellers or sports arena chaos - camera responsiveness is non-negotiable.

Sony RX100 VA delivers a maximum continuous shooting rate of 24 fps (frames per second) in speed priority mode, an impressive feat allowing you to capture fleeting moments in bursts with retained autofocus via its hybrid AF system. This high frame rate, combined with 315 focus points, makes tracking erratic movement feasible.

Casio EX-ZR400 offers a blistering 30 fps burst rate, but this chops focus tracking as it uses a fixed focus point in burst mode - a typical limitation of small sensor superzooms. So while you get lots of frames, many may be out of focus or blurrier if subjects move unpredictably.

Moreover, the Casio’s contrast-only AF lags behind Sony’s hybrid system in precision and reaction time, a critical factor for sports shooters chasing rapid play action.

Street Photography: Stealth and Quick Reflexes

Street photography thrives on discretion and spontaneity. Here, a camera’s profile and operational speed are paramount.

The Casio’s slim, low-profile body is an asset; it's less intimidating in social settings and slips easily in a pocket. But its autofocus lag and slower startup can mean missed moments.

Sony’s slightly thicker RX100 VA is quick to start, autofocus is snappy, and the tilting screen helps compose candid shots from unconventional angles. However, its shiny lens barrel and EVF might draw more attention on the street - even if it rewards with image quality.

Both tackle low-light street scenes with varying success: Sony’s superior sensor handles neon-lit streets and dim cafés better; Casio’s smaller sensor and slower lens force higher ISO and thus more grain.

Macro and Close-Ups: Precision and Magnification

Macro photography requires close focusing and stability. Casio’s minimum focus distance is impressive at 1 cm, beating Sony’s 5 cm minimum.

Though Casio’s zoom outperforms at true macro distances, image quality hits limitations due to sensor size and lens resolving power. Detail can be softer upon frame edges.

Sony’s RX100 VA, despite longer minimum focus distance, benefits from its large sensor and sharp optics to render fine textures crisply - useful if you’re willing to move physically closer or use focus stacking techniques.

Additionally, Sony’s superior stabilization aids handheld macro shooting, reducing blur and offering more creative freedom.

Night and Astro Shooting: ISO Performance and Long Exposure

Astrophotography or night shots put sensors through extreme tests - pushing high ISO performance, noise control, and exposure accuracy.

Sony’s RX100 VA shines with native ISO up to 12,800 and boosted ISO 25,600. Superior sensor technology yields lower noise levels at these sensitivities compared to the Casio’s max native ISO 3,200, which is more prone to luminance and chromatic noise.

Exposure controls, including manual shutter and aperture, exist on both, but the Sony offers the benefit of an electronic shutter enabling speeds as fast as 1/32000s and true silent shutter modes - handy for shooting in quiet environments without camera shake.

Although neither is a dedicated astro system, the RX100 VA’s sensor and extended ISO range provide better chances to capture stars and nightscapes with detail - something I verified under starry skies using long exposures.

Video Capabilities: 1080p vs 4K - Not Just Megapixels Matter

Videographers have benefited greatly from compact camera advances, though compromises often remain.

Casio’s EX-ZR400 outputs 1080p at 30 fps using H.264, with several slow-motion modes up to 1000 fps in lower resolutions - a novelty for ultra-slow-motion enthusiasts. However, lack of microphone input and basic stabilization limit serious video use.

Sony takes the cake with 4K (3840 x 2160) at 30 fps in XAVC S format and supports built-in optical stabilization. The RX100 VA’s 4K video quality, combined with better autofocus in video mode, makes it suitable for vloggers and casual filmmakers wanting compact 4K capability without carrying a larger rig.

Both cameras lack headphone jacks and mic inputs, curtailing audio monitoring and external recording possibilities - a common compact camera compromise.

Travel Photography: Battery Life, Weight, and Versatility

True travel companions balance image quality, battery endurance, and form factor.

Casio boasts an impressive 500-shot battery life (CIPA standard) on a lighter body, a definite plus on longer trips without recharging options. Sony’s RX100 VA, with more demanding sensor and OLED EVF, manages about 220 shots - typical for high-performance compacts but necessitating spares or USB charging en route.

Looking at lens versatility, Casio’s 24–300mm superzoom offers reach for landscapes and cityscapes without swapping lenses, appealing to travelers prioritizing simplicity.

Sony’s 24–70mm range, albeit narrower, covers wide-angle through short telephoto, arguably the sweet spot for typical travel needs - accompanied by APS-C and full-frame mirrorless options should you want more reach.

Professional Use and Workflow: Formats and Reliability

For professional photographers needing reliable workflows, file output and build quality are decisive.

Sony RX100 VA supports RAW shooting, enabling superior post-processing flexibility - crucial for critical color grading or noise reduction workflows. Casio offers JPEG only, limiting creative control over final images.

Neither camera offers weather sealing; however, Sony’s professional lineage and build quality feel more reassuring for travel pro work.

Connectivity and Extras

Sony edges ahead with built-in wireless - Wi-Fi and NFC - enabling rapid image transfer to phones and remote control via apps. Casio EX-ZR400’s Eye-Fi card support offers wireless capability but relies on external memory cards, a less elegant solution.

Both have HDMI output, but neither offers USB charging standard (Sony uses a proprietary battery), so spare batteries remain wise investments.

Final Scoreboard: Performance by Genre

From portraits to sports, Sony RX100 VA dominates in most categories thanks to its sensor, AF, and lens advantages. Casio holds ground chiefly in travel (due to zoom range and battery life) and casual macro due to minimum focusing distance.

Overall performance measured across major photographic disciplines:

Where Sony RX100 VA ranks as a premium compact powerhouse, Casio EX-ZR400 positions as an affordable, flexible point-and-shoot.
