Casio EX-100 vs. Sony RX100 VA: An Expert Hands-On Comparison for Enthusiasts and Professionals

In the realm of high-performance compact cameras, two models from different eras and philosophies stand out: the Casio EX-100, a 2014 small sensor superzoom marvel, and the Sony RX100 VA, a 2018 large sensor compact with a fine balance of image quality and portability. Both cameras pack a punch for photographers seeking advanced features in a pocketable form, yet their design choices, sensor technology, and real-world usability tell quite different stories.

Having spent months extensively shooting, testing, and analyzing both these cameras across multiple photography genres, I am excited to present a detailed head-to-head that will guide enthusiasts and professionals alike in making an informed choice. Let’s dive into every critical aspect - from ergonomics to image quality, autofocus performance to video capabilities, and value-for-money considerations - using firsthand experience and technical analysis.

Handling and Ergonomics: Size Matters - But How Much?

Compact cameras often walk the tightrope between portability and comfortable handling. The Casio EX-100 and Sony RX100 VA both emphasize pocketability but interpret this in distinct ways.

Physically, the Casio EX-100 measures 119 x 67 x 50 mm and weighs roughly 389 grams, making it noticeably larger and heavier than RX100 VA’s 102 x 58 x 41 mm and 299 grams. That extra bulk in the Casio translates mainly into a more substantial grip and slightly larger lens barrel due to its 10.7x zoom range. The Sony, in contrast, opts for a denser but sleeker chassis that’s easier to slip into a coat pocket.

The Casio’s body shape yields better stability during one-handed shooting, which tactile shooters appreciate, especially when using longer focal lengths or longer exposures. On the downside, the EX-100 forgoes any electronic viewfinder, relying exclusively on its bright, large 3.5-inch Super Clear LCD, which tilts to aid shooting from awkward angles. The Sony RX100 VA sports a smaller but sharp 3.0-inch tilting screen augmented by a built-in pop-up electronic viewfinder (EVF) with 2.36-million dots. This EVF, although small, is invaluable for bright environments and precision framing that LCDs can struggle with outdoors.

Control layout also reflects design priorities. The Casio’s traditional button and dial placements emphasize simplicity, while the Sony’s top-deck arrangement feels more refined for advanced users, with well-placed dials for shutter speed and exposure compensation.

The RX100 VA’s controls are slightly more tactile and responsive, making for faster adjustments when shooting in dynamic conditions. Casio’s interface responds adequately but lacks the finesse and customization options professionals crave.

In everyday carry, the Sony RX100 VA undeniably wins on sheer portability and thoughtful design, while the Casio EX-100 offers a reassuring heft and an exceptionally large rear display that pleases manual shooters.

Sensor Technology and Image Quality: Size and Resolution Battle

Arguably the most defining characteristic of these two cameras lies in their sensors and resultant image quality. The Casio EX-100 features a 1/1.7" CMOS sensor measuring 7.44 x 5.58 mm and producing 12 megapixels (4000 x 3000). The RX100 VA, on the other hand, sports a much larger 1" back-illuminated CMOS sensor at 13.2 x 8.8 mm with 20 megapixels (5472 x 3648).

While sensor size isn’t everything, this difference equates to roughly 2.8 times the sensor area. Larger sensors invariably collect more light and produce cleaner images, especially at higher ISOs. Sony's BSI-CMOS design further enhances light-gathering efficiency, critical for low-light and dynamic range performance.

In controlled studio tests and real-world field shoots, the RX100 VA consistently delivers superior detail, richer colors, and lower noise levels beyond ISO 800. Landscape shots reveal the RX100's edge in resolving fine textures and subtle tonal gradations. The Casio EX-100, while respectable for a small sensor superzoom, shows more noise and diminished sharpness as ISO rises, attributable to its smaller sensor and older processing engine.

Color rendition on the Sony also trends towards more neutral and natural skin tones, which benefits portraiture immensely. The Casio leans slightly towards warmer hues, which might suit some artistic preferences but sometimes skews accuracy.

Autofocus Systems and Speed: Tracking the Action

Modern photography demands reliable autofocus (AF) in both stills and video. Here, the cameras diverge sharply. The Casio EX-100 uses contrast-detection AF with 25 focus points and face detection but lacks phase-detection points. The Sony RX100 VA integrates a hybrid AF system combining 315 phase-detection points with contrasting autofocus, enabling faster and more precise focusing.

This difference becomes glaring in dynamic shooting situations such as wildlife or sports. The Casio can hunt a bit in lower contrast environments and struggles to maintain lock on fast-moving subjects, despite its ability to shoot bursts up to 30 frames per second (fps) - a number that on paper might sound remarkable, but in practice, is hampered by slower buffer clearing and less reliable AF tracking.

Conversely, the Sony RX100 VA, though limited to 24 fps maximum burst, features highly effective AF tracking that manages eye detection and subject tracking with impressive accuracy. Its phase-detection points cover much of the frame area and provide superior responsiveness under mixed lighting.

Flash and Image Stabilization: Help When the Light Dips

Both cameras incorporate built-in flashes, but their specifications differ:

• Casio EX-100: Flash range ~6.1 meters, basic modes including auto and red-eye reduction
• Sony RX100 VA: Flash range up to 10.2 meters at Auto ISO, with advanced modes such as Slow Synchro and Rear Sync

The Sony's flash offers more versatility for creative lighting control and better power, enhancing low-light fill options.

Regarding stabilization, the Casio employs sensor-shift stabilization, while the Sony uses optical image stabilization. My tests reveal that the Sony’s OIS reduces handheld blur more effectively, especially at longer shutter speeds or zoomed focal lengths.

LCD Screens and Viewfinder Usability: Seeing Your Shot

The Casio’s large 3.5-inch Super Clear LCD at 922k dots is arguably its standout physical feature. The tilting mechanism - though limited to certain angles - makes composing low-angle shots comfortable, and the screen’s brightness is commendable.

The Sony RX100 VA’s 3.0-inch screen has a higher resolution (1229k dots), is also tilting, and works well in the field, but it’s also accompanied by the EVF previously mentioned, which the Casio lacks entirely.

In direct sunlight, the Sony’s EVF proves indispensable for framing accuracy, especially with fast-moving subjects or when precision is paramount. Though some might prefer the Casio’s large screen for studio shooting or tripod use, I found the presence of an EVF increases overall shooting confidence outdoors.
