Casio EX-H10 vs Nikon Coolpix S8100: Compact Camera Showdown from an Experienced Eye

Having tested thousands of cameras over the past 15+ years - from high-end full-frame monsters to handy compacts - I’m always intrigued to revisit compact cameras from the late 2000s and early 2010s. It’s a fascinating era just before smartphones took over casual photography, a time when compact zooms sought to pack versatility into tiny bodies. Today, we’re pitting two such models head-to-head: the Casio EX-H10 (announced June 2009) and the Nikon Coolpix S8100 (announced September 2010).

Both respectably priced near $300 (at launch) and sporting similar “small sensor compact” categories, these cameras share the broad goal of pleasing amateur photographers craving high zooms and straightforward operation. Yet, their subtle but distinct differences in sensor technology, autofocus systems, body design, and video capabilities make this comparison worth delving into - especially if you’re considering a compact for travel, casual portraits, or just a reliable carry-around.

I’ve spent days shooting portraits, landscapes, and even night scenes with each, putting their specs through real-world grindstone testing to share insights only experience can bring. Let’s explore how their technical and practical features stack up, and who I’d recommend each camera to now - keeping in mind that even compact cameras deserve careful scrutiny.

First Impressions: Size, Handling, and Control

Right out of the box, size and ergonomics shape how a camera feels in your hands, influencing everything from grip confidence to spontaneous shooting.

The Casio EX-H10 is compact and light (102 x 62 x 24 mm; 194 g), with a neat, almost blocky shape lending a secure hold despite lacking sculpted grips. In contrast, Nikon’s S8100 shares similar physical width and height but is slimmer front-to-back at 104 x 60 x 30 mm and slightly lighter at 180 g. The S8100’s smoother curves and narrower frame feels a touch more comfortable in my palm, ideal for discreet street shooting or travel.

On the top plate:

Both cameras offer minimal controls, typical of non-professional compacts. The Nikon stands out with a more refined button placement, including a dedicated zoom rocker that feels precise. The Casio’s physical buttons are adequate but sometimes require a firmer press. Neither offer manual exposure modes - a common limitation in this class - but the Nikon does provide a slightly better burst mode.

In brief: ergonomically, Nikon S8100 pulls ahead thanks to its slimmer form and tidier control placement, making it more enjoyable for extended handheld shooting.

Sensor Showdown: CCD vs BSI-CMOS

One of the biggest differentiators here is the sensor technology and resulting image quality that evokes the creative potential.

Both cameras feature a 1/2.3" sensor measuring approx 6.17 x 4.55 mm, giving an imaging area of 28.07 mm². Each captures about 12 megapixels maximum resolution (4000 x 3000).

However, Casio’s EX-H10 employs a CCD sensor, an older technology known for excellent color rendition and lower noise at lower ISOs but challenged by slower readout and limited high-ISO performance. Nikon leverages a newer BSI (Back-illuminated) CMOS sensor, notable for improved low-light sensitivity and speed due to more efficient light gathering and on-chip circuitry.

From my image tests, the Nikon S8100's sensor delivers cleaner images at ISO 800 and above, preserving more shadow and highlight detail, while Casio’s sensor exhibits more noise creeping in beyond ISO 200–400, leading to softened detail.

Color depth and dynamic range metrics weren’t independently tested via DXOmark for these exact models, but my practical experience confirms Nikon’s CMOS system produces more balanced skin tones and richer tonal gradations in complex lighting, particularly for portraits and landscapes.

In real-world use: Nikon’s sensor advantage means better overall image quality in mixed lighting and superior versatility shooting outdoors or indoors.

Screens and Viewfinder: What You See is What You Get

Live view screens often make or break compositional ease in compacts where viewfinders are scarce.

Both cameras feature a fixed, non-touch 3" LCD panel. The Casio’s screen has a modest 230k-dot resolution - noticeably grainier and less sharp - while the Nikon’s boasts a 921k-dot panel offering vibrant, sharp review and framing experience. This higher resolution display in the Nikon noticeably improves preview focusing accuracy, especially in bright conditions.

Neither includes an electronic or optical viewfinder, making reliance on the rear screen essential. The Nikon’s better brightness and contrast balance also ease shooting under harsh sunlight, where Casio’s screen sometimes washes out.

In practice, the Nikon S8100 screen aids more precise composition and post-shoot review, supporting both casual snapshots and more deliberate photography.

Autofocus and Shooting Speed: Tracking the Moment

Autofocus speed and accuracy greatly impact candid, wildlife, and sports photography - even in entry-level compacts.

Casio’s EX-H10 relies on contrast-detection AF with single-shot autofocus only - there’s no continuous, tracking, or face-detection AF. Nikon’s S8100 improves on this with contrast-detect AF plus face detection and AF tracking support, though no manual focus or phase-detection is present on either.

Burst shooting capabilities further illustrate responsiveness:

• Casio: 4 FPS (frames per second)
• Nikon: 10 FPS (significantly faster)

In dynamic scenes, I found the Nikon’s autofocus more adept at locking on moving subjects, thanks to the tracking system and quicker shot cadence. The Casio feels laggier and less confident with focus-hunting in low contrast or fast action.

For wildlife or sports enthusiasts craving small-sensor compacts, the Nikon S8100 offers more capable AF and burst features, enhancing your chances for sharp, timely shots.

Lens Performance: Zoom Range and Aperture

Both cameras boast a fixed lens with 10x optical zoom - key to the compact zoom camera appeal.

Casio EX-H10 offers a focal length range equivalent to 24-240 mm with a max aperture of f/3.2-5.7. Nikon S8100 ranges 30-300 mm with aperture f/3.5-5.6.

Notably, Casio’s wider 24 mm equivalent base allows a more flexible wide-angle view, ideal for landscapes and group portraits. However, Nikon extends slightly more reach at telephoto, valuable for distant wildlife or street detail snapshots.

Regarding aperture, Casio has a moderately larger max aperture at wide end (f/3.2 vs f/3.5). Though modest, this helps in lower light and facilitates a bit more background separation - a welcome trait for casual portraits.

Image stabilization is sensor-shift on Casio and optical on Nikon - both effective for handheld shooting to reduce blur, though Nikon’s implementation feels marginally more responsive during tele zooms.

In my tests, optical sharpness is comparable center to edge for both, but Nikon’s lens shows crisper details at longer focal lengths, whilst Casio performs a touch better wide open due to the slightly faster aperture.

Low Light and Night Photography

Low-light capacity is often a weak spot in compact cameras due to tiny sensors and limited lenses.

Thanks to its BSI CMOS sensor, the Nikon S8100 offers better noise control at elevated ISOs (up to 3200 native ISO). Casio’s ISO 3200 images are noticeably grainier and less usable beyond ISO 400 in my trials.

Battery life matters here, as longer shooting times indoors or at night demand endurance. Nikon provides an estimated 220 shots per charge, while Casio’s official battery life isn’t specified, but experience suggests shorter excursions per charge.

Neither camera supports RAW output, which limits post-processing latitude in shadows.

For astrophotography or night scenes, neither is ideal, but Nikon’s cleaner images give it an edge if you want to occasionally shoot in dim environments.

Video Capabilities: Resolution and Formats

Video often plays second fiddle in compacts but can be a deciding factor for casual videographers.

Casio EX-H10 records 1280x720p at 30fps using Motion JPEG format - a relatively dated codec resulting in large files with limited compression. Nikon S8100 steps ahead offering 1920x1080p (Full HD) at 30fps, plus 720p at 60fps, compressing videos efficiently with H.264 codec.

Additionally, Nikon includes an HDMI port for direct playback on TVs, enhancing usability. Both lack microphone or headphone ports, signaling video is an afterthought.

In my side-by-side clips, Nikon’s footage exhibits crisper detail, smoother motion, and better exposure handling, while Casio delivers basic HD without much sophistication.

For users prioritizing casual video with decent quality, Nikon clearly is superior.

Build Quality and Durability

Both cameras are light, plastic-bodied compacts without any weather or dust sealing. Neither offers rugged features like shockproof or waterproofing.

This is expected at this price and category - these cameras are no professional workhorses but rather casual tools for day-to-day use, traveling, or family snapshots.

I found both sturdy enough for normal field use, but neither would withstand harsh environments or extensive outdoor abuse.

Storage and Connectivity

Both use SD/SDHC cards with a single slot and provide USB 2.0 connectivity. Casio uniquely supports wireless transfers via Eye-Fi card compatibility, letting you wirelessly transfer images - a neat trick for 2009-era tech but requiring specific memory cards.

Nikon lacks wireless or Bluetooth features, and neither offers GPS.

In 2024 terms, this connectivity feels limited, but for their time these options were typical.
