Casio EX-H20G vs Olympus Stylus 9000: A Hands-On Comparison of Small Sensor Compact Cameras

Over the course of my 15+ years of camera testing, I’ve come across myriad compact cameras boasting “bridge” capabilities with zoom ranges, sensor tech, and image quality that appeal to both casual shooters and serious enthusiasts needing pocketable options. Today, I’m diving deep to compare two somewhat contemporaneous small-sensor compacts: the Casio EX-H20G announced in late 2010, and the Olympus Stylus 9000 (also known as the mju 9000), which hit the market earlier in 2009. Both cameras targeted photography enthusiasts hungry for versatile focal ranges up to 10x optical zoom, packed into small bodies. At their original asking prices - both around $300 - these cameras promised solid value for the travel and casual shooter who didn’t want to lug large gear.

I’ve spent considerable time with both cameras to assess real-world performance across a wide range of photography disciplines, from portraits to landscapes to action shooting. I’ll share not just specs, but what these mean in practice: how images look, how handling feels, and how each camera fits into different use cases. For context, both cameras have small 1/2.3" CCD sensors, fixed lenses, no raw support, and sensor-shift image stabilization, so the decision ultimately boils down to nuanced differences in optics, UI, and image quality characteristics.

Let’s explore these contenders in detail, featuring the full scope of my hands-on experience.

First Impressions: Size, Ergonomics, and Build Quality

Before pressing the shutter, the feel of a camera in your hands shapes your shooting pleasure significantly. Both the Casio EX-H20G and Olympus 9000 fit into the compact category, but their design philosophies differ in subtle yet meaningful ways.

The Casio EX-H20G measures approximately 103mm x 68mm x 29mm and weighs 216 grams, while the Olympus Stylus 9000 is slightly smaller at 96mm x 60mm x 31mm and a touch heavier at 225 grams. I found the Casio's body to be a bit chunkier but more substantial, with slightly better grip contours making it easier for extended handheld use. The Olympus is slimmer and feels a touch more pocket-friendly, though I found it a bit less comfortable to hold steady for longer periods due to its more rounded, sleeker design with less pronounced grip.

In terms of build, neither camera is weather-sealed, dustproof, or shockproof - expected for their era and class. Their plastic constructions feel decent, though not rugged. Buttons are not illuminated on either model, which made night shooting or low-light navigation a small challenge. The Casio’s buttons exhibit firmer, more tactile feedback than the softer feel on the Olympus.

Both have a fixed 3-inch (Casio) or 2.7-inch (Olympus) LCD that sits on the back, with no tilting or touch capabilities.

Here, the Casio has a slightly more intuitive control layout with dedicated zoom toggle and exposure compensation access (though it doesn’t actually support exposure compensation) - a bit odd but user-friendly nonetheless. The Olympus’s top controls are more minimalistic, which may appeal to photographers favoring a simpler setup.

Sensor and Image Quality: Exploring the Limits of 1/2.3” CCDs

Both cameras pack a 1/2.3" CCD sensor, about 6x4.5mm in size - quite small by today’s standards but typical for compact cameras of their vintage.

The Casio EX-H20G has a 14-megapixel resolution at 4320 x 3240 pixels; the Olympus 9000 sports a slightly lower 12-megapixel resolution at 3968 x 2976 pixels. While that sounds like a win for Casio, resolution isn’t everything, especially when sensor size is small and pixel density impacts noise and dynamic range.

From my shooting tests - comparing images taken simultaneously under identical lighting using both cameras - I noticed:

• Color Fidelity: Casio images were slightly more vibrant, with a noticeable warmth in skin tones and greens. Olympus trended towards cooler tones, sometimes appearing a touch muted but quite neutral overall.

• Noise Performance: Both cameras struggle at higher ISOs (above 400), but the Casio’s maximum ISO is 3200 (though practically noisy), whereas the Olympus caps at ISO 1600. Interestingly, Olympus’s images held onto better detail at ISO 800, likely owing to slightly larger pixels given the lower megapixel count.

• Dynamic Range: Shadows and highlights were compressed in both cameras, with neither offering a wide dynamic range. Casio’s images clipped highlights more abruptly, while Olympus maintained more shadow detail.

• Lens Sharpness: The Casio’s lens delivered crisper center sharpness at wide angles with slight softness creeping in at telephoto range. Olympus’s lens was softer overall but displayed slightly better edge-to-edge sharpness.

• Color Depth and Saturation: Without raw support, both cameras rely heavily on in-camera JPEG processing. Casio offered more saturated colors, which some photographers may like for casual use but is less faithful for professionals seeking neutral renders.

In my opinion, for landscapes and general travel captures where punchy colors are welcome, Casio holds a slight edge. For portraits requiring more natural skin tone rendition, both cameras are adequate but neither approaches the quality of later compacts or mirrorless cameras.

Focusing Systems: How Quick and Accurate?

Both cameras use contrast-detection autofocus systems, common for compact cameras. Neither offers phase-detection or hybrid autofocus that has become the norm on advanced cameras.

I found that the Casio’s autofocus system felt a bit slower, especially in low-light or low-contrast scenes, with noticeable hunting before locking focus. The Olympus, surprisingly, was a bit faster in comparable conditions, though neither camera could keep up with fast-moving subjects.

Macro focus is an interesting point: the Casio focuses down to 7 cm, whereas Olympus can focus nearly twice as close at 1 cm. This difference made Olympus a better choice for close-up flower or insect photography, though lack of focus stacking or post-focus limits creative control.

Zoom Lenses, Apertures and Real World Use

Both cameras provide a 10x optical zoom with roughly similar focal length ranges:

• Casio EX-H20G: 24-240mm (35mm equivalent), aperture f/3.2–5.7
• Olympus Stylus 9000: 28-280mm (35mm equivalent), aperture f/3.2–5.9

While Olympus extends a little further telephoto at 280mm, Casio begins wider at 24mm for true wide-angle framing.

In practice, I appreciated the Casio’s wider 24mm end when shooting landscapes and architecture. The slightly larger lens elements afforded better distortion control, although barrel distortion was noticeable in both lenses at the widest settings.

At telephoto settings, both lenses soften, though Olympus’s lens edges stay marginally sharper. Aperture differences were comparable, with both stopping down to f/5.7–5.9 telephoto, which is quite slow for action photography or low light.

Despite their small sensor size magnification factors (~5.8 to 5.9), image stabilization was helpful to mitigate handshake, especially at long zoom. Both cameras have sensor-shift IS, which performs adequately for static scenes but suffers under rapid movements.

Screens, Viewfinders and Usability

Neither camera offers an electronic viewfinder, requiring reliance on LCD screens.

The Casio’s 3-inch, 461k-dot screen offers a brighter, crisper display compared to Olympus’s smaller 2.7-inch, 230k-dot monitor. When shooting outdoors on bright days, the Casio screen was markedly easier to compose with, though both lacked anti-reflective coatings.

User interfaces are basic on both models, with menu-driven controls and no touch inputs. The Casio offers more granular manual focus options, while Olympus has fewer user-adjustable settings.

Video Capabilities: Modest, Yet Present

For multimedia users, video recording specs differentiate the two slightly:

Casio clearly offers better video options with its HD 720p capture in H.264 codec, delivering more usable footage for casual video recording or travel vlogging. The Olympus’s VGA resolution video is rather outdated, with lower detail and compression artifacts.

Neither camera provides external microphone inputs, making audio quality dependent on built-in mics.

Battery Life and Storage

Battery life specs for these cameras are not officially published, but:

• Casio uses the NP-90 Lithium-ion battery, which I found good for about 300 shots per charge under mixed usage.
• Olympus’s battery model isn’t specified, but practical use suggested similar endurance.

Storage also varies: Casio supports widespread SD/SDHC/SDXC cards, a modern and versatile choice, while Olympus uses xD Picture Cards and microSD cards plus internal storage. xD cards are rarer, less capacious, and more expensive, making Casio more practical from a cost and capacity standpoint.

Connectivity Features: GPS vs Wireless

An interesting divergence is Casio EX-H20G’s built-in GPS for geotagging versus Olympus 9000’s lack of any wireless or geographic features.

On trips, I found the EX-H20G’s GPS to be a handy tool to automatically tag shots, useful for cataloging travel memories. Both cameras offer USB 2.0 for data transfer, but Casio alone has HDMI output for easier TV viewing.

Casio also supports Eye-Fi cards for wireless image transfers, whereas Olympus offers no wireless connectivity.

Shooting Across Photography Genres: What Fits Each Camera?

Let me share how these cameras fared as practical tools across a range of popular photography styles.

Portrait Photography

Portrait shooting demands accurate skin tones, decent bokeh, and eye detection for critical focus. Sadly, neither camera features face or eye detection AF. Both rely on single-spot contrast autofocus.

The Casio’s warmer color rendition produced more pleasing skin tones out of camera, giving images a lively feel. Olympus’s cooler tones are less flattering unless adjusted in post.

At apertures f/3.2–5.7, both cameras yield limited background blur with their small sensors and zoom lenses - enough for casual portraits but not artistically creamy bokeh.

Landscape Photography

Wide-angle reach and dynamic range are key here.

Thanks to the Casio’s wider 24mm equivalent and crisper center sharpness, it excels slightly for landscapes. Olympus’s smaller screen and lower resolution limit composition framing cues.

Neither camera performs well in high dynamic range scenes, so careful exposure and post-processing trickery are required. Weather sealing is absent on both, so caution in harsh conditions is needed.

Wildlife and Sports

For fast-moving subjects, autofocus speed and burst rate matter; both cameras lack continuous AF and advanced tracking. Burst rates are not specified but generally low.

Casio’s wider zoom range and GPS help with framing and location data, but slow AF hunting diminished its effectiveness for wildlife. Olympus fares no better here.

Street Photography

In street settings, portability, quick AF, and discretion count.

Olympus’s smaller size aids inconspicuous shooting, while Casio’s better grip helps stability. Low-light AF was slow on both.

Macro Photography

The Olympus’s 1 cm macro focus outpaces Casio’s 7 cm, enabling closer shots of details. Neither provides focus stacking or specialized macro modes.

Night and Astro Photography

Small sensors limit noise control here. Casio’s max ISO 3200 is appealing on paper but very noisy in practice. Olympus max ISO 1600 is cleaner but less sensitive.

Long shutter speeds (up to 2 seconds) are possible, but low-light usability is generally poor.

Video and Travel Use

Casio stands out with HD video and GPS, making it a better travel companion for multimedia enthusiasts.

Olympus’s limited video resolution and no geo-tagging diminish its travel versatility.

Professional Workflows

No raw support on either camera limits post-processing flexibility, ruling them out for demanding professional use.

Image Samples: Seeing Is Believing
