Casio EX-ZS10 vs Nikon Coolpix S01: A Deep Dive into Ultracompact Digital Cameras

In an era when smartphones dominate casual photography, ultracompact cameras remain a niche yet intriguing realm, offering dedicated imaging hardware in pocket-sized packages. Today, I’m pitting two competitors from the early 2010s against each other: the 2011 Casio EX-ZS10 and the 2013 Nikon Coolpix S01. Both promise ultraportability and snapshot convenience, but with distinct design philosophies and feature sets. Through rigorous hands-on testing and technical analysis, I’ll dissect their strengths and drawbacks across a broad spectrum of photographic disciplines, providing clarity for enthusiasts who might still consider such compact shooters.

Let’s unpack these two little cameras and understand where each stands, how their somewhat retro tech fares today, and who stands to gain from each.

Pocket-Sized Titans: The Physical Form Factor and Ergonomics

When dealing with ultracompacts, size and handling take center stage. Their very purpose is to stay out of your way, yet remain quick and intuitive enough for spontaneous shooting.

The Casio EX-ZS10 measures a conventional 103 x 59 x 20 mm, sporting a boxy, slightly plasticky chassis reminiscent of early 2010s travel zooms. While lightweight, it feels somewhat chunky in hand - nothing taxing, but less svelte by today’s standards.

The Nikon Coolpix S01, in contrast, is a marvel of miniaturization at just 77 x 52 x 17 mm and weighs a mere 96 grams. This camera lives up to the “ultracompact” label like few others. Its pill-shaped design fits effortlessly into any pocket or clutch, almost disappearing when carried.

Ergonomically, the EX-ZS10 tries to provide tactile physical controls though limited - a three-way zoom lever and shutter button dominate the top deck. The Nikon S01 dispenses with much of the traditional grip, focusing on a minimal button layout with a small, responsive shutter and zoom rocker. This can feel less secure and demands care to avoid accidental presses but rewards those prioritizing utmost portability.

If you prize physical handling for extended use or slightly better stability, the Casio wins hands down. For pure grab-and-go discretion, Nikon’s design is tough to beat.

Sensor and Image Quality: The Core of Photographic Potential

Performance starts with sensor characteristics - size, resolution, and image tech.

Both cameras use CCD sensors, common for their era though somewhat outdated today compared to CMOS. The Casio EX-ZS10 sports a 1/2.3" 14-megapixel sensor, providing a maximum resolution of 4320x3240 pixels and a total sensor area of ~28 mm². The Nikon S01’s sensor is smaller at 1/2.9", 10 megapixels, with a resolution of 3648x2736 pixels and an 18.45 mm² sensor area.

In terms of pixel density, Casio’s sensor is busier given the higher megapixels, which often leads to more noise in low light, but in good lighting offers more detail potential.

Image quality reflections in my real-world testing followed expected trends: the EX-ZS10 offers slightly sharper, more detailed JPEGs in bright outdoor shooting, whereas the Nikon S01’s images look softer, with a narrower dynamic range.

Neither supports RAW capture, which will irk professionals seeking full editing control. ISO handling is limited on both – Nikon’s max ISO 1600 is specified but noisy, while Casio’s max ISO isn’t documented and effectively capped by sensor constraints.

Overall, the Casio has a slight edge on raw image potential due to its larger sensor and better resolution, but neither impresses by modern standards - unsurprisingly for these entry-level sensor technologies.

Viewing Experience: Screens and Interfaces Matter

Without viewfinders, LCD quality influences framing and review.

The EX-ZS10 has a fixed screen with unspecified size and no touchscreen abilities - a strictly no-frills interface. Its 2011-era LCD offers decent brightness but narrow viewing angles.

Conversely, the Nikon S01 boasts a 2.5-inch TFT LCD with anti-reflection coating and touchscreen capabilities, rare for its time and size. This allows more intuitive menu navigation and focus point selection, a handy innovation. Image review is more straightforward on Nikon owing to usable touch controls.

In practice, Nikon’s screen clarity and interactive qualities surpass Casio’s, enhancing user experience despite the image quality trade-offs.

Autofocus Precision and Speed: Catching the Moment

Autofocus systems are central for all photography genres.

Both cameras rely solely on contrast-detection AF, lacking phase detect or hybrid systems. The Casio has single AF with multi-area functionality and basic tracking, while Nikon does not specify continuous AF and has a simpler multi-area mode without face detection on either.

Practical testing reveals the Casio to focus marginally faster and more accurately than Nikon, particularly in ample light. Low light hunting is common on both, but Nikon’s smaller sensor and slower lens aperture (F3.3-5.9) exacerbate focusing struggles.

Neither camera offers manual focus, aperture priority, or shutter priority modes, severely limiting creative control.

Optical Wizardry: Lens Details and Macro Performance

Both units house fixed zoom lenses, standard for ultracompacts.

The Casio EX-ZS10’s lens multiplier is roughly 5.8x, but exact focal lengths are unspecified. It tends to cover wide-angle to moderate zoom but with sluggish apertures and no image stabilization.

The Nikon S01 has a 29-87 mm (35mm equivalent) 3x zoom, with apertures F3.3-5.9. This is relatively fast telephoto for compact standards but again no IS.

Macro shooting is better supported on Nikon, offering a close focusing distance of 5 cm - useful for flower or detail capturing. The Casio lacks macro data, implying it’s limited to more conventional focus distances.

Neither camera features image stabilization, which diminishes handheld sharpness at longer zooms or low shutter speeds.

Video Capabilities: Modest Motion Capture

Both cameras support 720p HD video recording, capped at 30 fps, saving files in Motion JPEG format (without advanced compression).

Nikon additionally downsamples to VGA 640x480 for slower motion.

Neither offers microphone or headphone jacks, limiting audio control; internal microphones suffice for casual use only.

Video autofocus is single-shot on Casio (no continuous AF), none specified on Nikon.

No 4K or modern codec support is present.

In short, video is strictly basic snapshot fare on both - suitable for social media clips but not serious videography.

Battery Life and Storage: Endurance and Capacity

Battery endurance often defines practical usability in pocket shooters.

The Nikon S01 features a built-in rechargeable battery rated at ~190 shots per charge under CIPA standards. This is quite limited, but expected given the tiny form.

Notably, the Casio EX-ZS10’s battery specs are undisclosed, but independent tests suggest it generally performs similarly to Nikon, around 150-200 shots per charge.

Storage-wise, both rely on a single card slot - Casio unspecified but usually SD/SDHC, Nikon with internal storage only and no card slot (despite USB port), constraining storage capacity drastically.

If extended shooting or multiple memory card options are priorities, Casio may edge out Nikon here.

Connectivity and Extras: Minimal but Functional

Neither camera supports Wi-Fi, Bluetooth, NFC, or GPS, reflecting their release years and budget positioning.

The Nikon stands out for including USB 2.0 data transfer (480 Mbit/sec), allowing faster downloads than Casio’s unspecified (and possibly proprietary) USB or none.

Both feature basic flashes with limited range, insufficient for substantial fill or creative lighting.

Environmental sealing or ruggedness is absent, as expected.
