Casio EX-FH25 vs Olympus SZ-11: A Detailed Comparison of Two Small Sensor Superzooms

In the niche realm of small sensor superzoom cameras, the Casio EX-FH25 and Olympus SZ-11 stand out as intriguing contenders from the early 2010s. Both were designed with high zoom versatility at their core, making them appealing options for casual photographers who crave an all-in-one solution without the bulk and expense of interchangeable lens systems.

But how do these two cameras - the Casio EX-FH25, a bridge-style superzoom with SLR-like design cues, and the compact Olympus SZ-11 - actually perform when put through their paces? Having spent hours shooting, testing, and dissecting their strengths and weaknesses across a broad spectrum of photography disciplines, I’ll break down every relevant detail. This comparison is tailor-made for enthusiasts and pros who want to understand which camera fits their needs best in portraiture, landscapes, wildlife, sports, street, macro, night photography, video work, travel, and professional use.

Let’s get started.

First Impressions: Design, Ergonomics, and Handling

When evaluating cameras, ergonomics and user interface often set the tone for real-world usability. The Casio EX-FH25 adopts an SLR-like (bridge) body style, lending it a solid grip and presence that mimics traditional DSLRs. Its dimensions (122x81x83 mm) and weight (~524 g) give it a comfortable heft without being too unwieldy for handheld shooting sessions. The Casio’s 3-inch fixed screen has a 230K-dot resolution - serviceable, though not spectacular.

Conversely, the Olympus SZ-11 opts for a compact, minimalist form factor, measuring just 106x69x40 mm and weighing only 226 g. This smaller footprint is ideal for travelers and street photographers prioritizing discretion and portability. Its 3-inch screen ups the ante with a crisp 460K-dot TFT LCD, delivering better clarity and live view precision.

When comparing these two visually and physically, the Casio’s bridge camera silhouette offers an intuitive grip and in-hand confidence, especially for longer telephoto shots. The Olympus prioritizes pocketability at the expense of some handling robustness.

On top, the Casio sports a more elaborate control scheme featuring dedicated mode dials and exposure compensation settings, while the Olympus leans into simplicity with fewer manual control options - expectations well aligned with their respective market segments.

Sensor and Image Quality: One Step Ahead or Staying Behind?

Both cameras utilize the same 1/2.3-inch sensor format measuring 6.17x4.55 mm with an effective sensor area of 28.07 mm². This sensor size is standard for superzoom compacts but naturally limits image quality potential due to smaller photosites and increased noise at higher ISO levels.

However, the Casio EX-FH25 employs a 10 MP backside-illuminated CMOS sensor (BSI-CMOS), optimized for better low-light sensitivity and dynamic range compared to traditional front-illuminated sensors. The Olympus SZ-11 sports a 14 MP CCD sensor, a technology admired for sharpness and color reproduction but which generally falls short on noise performance and speed.

In practical shooting tests, the Casio's BSI-CMOS sensor delivered cleaner images at ISO 400 and above, retaining finer detail and better shadow recovery. The Olympus’s higher resolution advantage is mostly theoretical - its increased megapixels amplify noise and reduce dynamic range, which affected both landscapes and shadow details.

In daylight, both cameras perform adequately, but low-light and indoor photos from the Casio edge out with smoother gradations and less chroma noise. Neither camera supports native RAW in a user-friendly format (Casio does technically offer RAW, but workflow is limited), so JPEG quality tuning and in-camera processing play key roles.

Autofocus and Shooting Performance: Fast Enough to Capture the Moment?

When it comes to autofocus (AF), the EX-FH25 relies on contrast-detection AF without continuous or tracking autofocus modes. It supports single AF only and lacks face or animal eye detection. The SZ-11 is a step ahead here, providing contrast-detection AF with face detection and basic tracking abilities, supported by multiple AF-area modes.

For wildlife or sports photographers who demand rapid and accurate tracking, neither camera will fully satisfy - autofocus speed and tracking reliability are limited by their sensor size, processor capacity, and AF tech of their era.

The Casio's standout feature is an extraordinarily high-speed continuous shooting mode - up to 40 frames per second (fps) at reduced resolution - ideal for capturing fleeting moments but with the caveat of lower image quality and fixed exposure during the burst. Olympus offers a more pedestrian burst rate at 7 fps, full resolution.

Handling Different Photography Genres: Strengths and Weaknesses Breakdown

Portrait Photography

Both cameras struggle to match DSLRs or mirrorless cameras with large sensors in achieving natural skin tones and creamy bokeh due to sensor size and lens design. Nonetheless, the Casio's wider aperture range (f/2.8–4.5) and slightly longer focal length reach aid in subject separation, producing acceptable background blur at telephoto lengths.

However, the Olympus’s facial detection AF helps newbies maintain sharp focus on faces - a practical advantage for casual portraiture. Neither camera offers eye AF or advanced AI focusing refinements.

Landscape Photography

For scenery and landscape applications, sensor resolution and dynamic range are paramount. The Olympus SZ-11’s 14 MP sensor provides more pixels to work with, ostensibly allowing for more expansive prints or digital cropping. But the downside is limited ISO range (max ISO 1600) and somewhat narrower dynamic range due to CCD sensor characteristics, leading to clipped highlight details in challenging lighting.

The Casio’s CMOS sensor, despite 10 MP resolution, captures cleaner shadows and recovers highlights better. Its aperture priority and manual exposure modes also give photographers greater creative control during tricky exposures. Weather sealing is absent on both, restricting these cameras’ use in adverse outdoor conditions.

Wildlife Photography

Thanks to the similar focal length multiplier (~5.8x) and extensive 20x optical zoom range, both cameras can function as entry-level wildlife shooters. Casio’s 26-520 mm (equivalent) lens edges slightly ahead with a faster aperture at telephoto (max f/4.5 vs f/6.9 on Olympus).

The Casio’s ultrafast burst mode (40 fps) theoretically makes it excellent for capturing fast action birds or animals - provided one contends with reduced resolution outputs during these sequences. Neither camera offers highly reliable continuous AF tracking, and lens sharpness at long reach favors the Casio.

Sports Photography

When it comes to sports, autofocus tracking precision and speed, as well as frame rate, matter immensely. Neither camera was designed as a sports tool, and this clearly shows.

Olympus has an AF tracking mode, yet the low burst speed (7 fps), combined with CCD sensor slow readout, limits its practical use in fast-paced action. Casio's higher fps is only applicable at lower resolutions and fixed focus/exposure, impairing usefulness for detailed sports shots.

Street Photography

Street shooters typically prize stealth, portability, and rapid responsiveness. The Olympus SZ-11’s compact dimensions and lighter weight provide a clear advantage for discrete shooting. Its silent shutter and face detection help capture candid moments more unobtrusively.

The Casio, while more comfortable in hand, is bulkier and more conspicuous - less ideal for stealth but better ergonomically for longer sessions. Both cameras perform acceptably in well-lit conditions but suffer in dim environments, where image noise becomes conspicuous.

Macro Photography

Close-up shooting benefits from focusing precision and minimum focus distance. Both cameras boast an impressive 1 cm macro focus range, allowing exceptional close-ups of small subjects - flowers, insects, textures - without additional equipment.

The Casio’s manual focus option adds creative flexibility, whereas Olympus’s autofocus may hunt more in tricky macro conditions. Both feature sensor-shift stabilization facilitating sharper shots handheld at macro distances.

Night & Astro Photography

For low-light and astrophotography, larger sensors, high ISO performance, and long exposure capabilities are critical.

Neither the Casio nor Olympus is truly suited for deep night or astro photography due to their small sensors and max ISO limits (Casio 3200, Olympus 1600). The Casio allows shutter speeds up to 30 seconds - a boon for long exposures - but noise control is mediocre at high ISOs.

Though not perfect, the Casio’s CMOS sensor outperforms the Olympus’s CCD in high ISO scenarios, resulting in cleaner starscapes and night scenes.

Video Capabilities

Here, Olympus takes a decisive lead with 720p HD video at 30 fps and HDMI output for external monitoring. Casio caps out at VGA (640x480) resolution, with high frame-rate options up to 1000 fps at severely reduced resolutions, catering mostly to experimental slow-motion clips rather than serious video work.

Neither camera has microphone or headphone jacks, limiting audio control, but Olympus’s TruePic III+ processor enhances video clarity and color.

Travel Photography

Picking a travel companion involves weighing versatility, size, battery life, and ease of use.

Olympus’s light body and modest price make it a good grab-and-go option, saving bag space when hiking or sightseeing. Casio’s heavier, larger form factor is less convenient but rewards with higher zoom versatility and refined controls - especially valuable when longer telephoto reach is needed.

Battery life favors Olympus’s proprietary rechargeable battery (~200 shots), whereas Casio runs on 4 AA batteries - flexible but less environmentally sustainable and a burden on longer trips.

Build Quality, Weather Sealing, and Durability

Neither camera incorporates weather sealing or ruggedized features. Both are vulnerable to moisture, dust, and physical shocks - common caveats for small sensor superzooms in their generation and class. The Casio’s more substantial form factor feels sturdier in hand, yet the Olympus’s compactness means fewer mechanical vulnerabilities.

If you prioritize outdoor reliability in inclement conditions, these cameras should be considered entry-level options only.

User Interface and Controls: How Intuitive Are They?

Without a touchscreen on either camera, navigation relies on physical buttons. Casio’s intuitive exposure compensation dial and dedicated manual controls serve users seeking creative flexibility. Olympus’s streamlined approach aims to simplify operation for beginners, cutting exposure modes and manual interventions.

Both cameras have fixed 3-inch LCDs, but Olympus’s much higher resolution screen provides a noticeably brighter, crisper view. Casio’s electronic viewfinder (albeit low resolution and unspecified specs) is a small plus for bright outdoor shooting where LCD glare is an issue.

Lens Ecosystem and Compatibility

Since both cameras utilize fixed zoom lenses (no interchangeable lenses), the choice lies solely in which native zoom and aperture suits your needs.

• Casio EX-FH25: 26-520 mm equivalent, f/2.8–4.5
• Olympus SZ-11: 25-500 mm equivalent, f/3.0–6.9

Casio’s lens’s wider maximum aperture range notably outperforms Olympus across the zoom range, especially at the telephoto end - benefiting low-light and depth-of-field control.
