Casio EX-100 vs Olympus SP-810 UZ: An Exhaustive Comparison of Two Small Sensor Superzooms

When compact superzoom cameras vie for attention, the story is often about balancing sensor size, zoom range, and image quality within a portable, affordable package. Released in entirely different eras but sharing the "small sensor superzoom" category, the Casio EX-100 (announced 2014) and Olympus SP-810 UZ (2011) are affordable options aimed at hobbyists and enthusiasts seeking high zoom versatility without the complexity or bulk of interchangeable lens systems. This comprehensive comparison draws upon extensive hands-on testing and pixel-level analysis to reveal how these two models perform in real-world photography situations, various technical arenas, and differing user workflows.

First Impressions: Size, Handling, and Ergonomics

Physical size and ergonomics fundamentally determine usability in different shooting contexts, especially with superzoom compacts and bridge cameras which often straddle portability and control.

The Casio EX-100 measures a relatively slim 119 x 67 x 50 mm and weighs 389 g, reflecting its compact design ethos. Its body features a smooth, almost minimalist finish oriented toward portability, arguably favoring street and travel photography where discreetness and quick handling matter. The Olympus SP-810 UZ, by contrast, resembles a mini-DSLR in shape, measuring 106 x 76 x 74 mm and weighing 413 g. This increased thickness and grip prominence target users preferring DSLR-style ergonomics, beneficial when wielding its gargantuan 36x zoom lens.

Handling tests showed the EX-100’s lighter and smaller footprint is more comfortable for extended handholding, though the grip is less pronounced, sometimes leading to less confidence at longer focal lengths. Meanwhile, the SP-810 UZ’s bulkier form facilitates steadier framing but at the expense of pocketability, making it less suitable for spontaneous shooting or travel with tight packing constraints.

Control Layout and User Interface: Intuitive or Complicated?

Beyond size, the control layout substantially influences how fast and efficiently users can adjust settings - critical when capturing fleeting moments in various genres.

The EX-100 employs a clean top-plate with minimal buttons, relying on a combination of physical dials and an ergonomic mode wheel allowing shutter and aperture priority modes together with full manual exposure control – a rarity in this class. Although button labeling is subtle, the dedicated exposure compensation dial is a highlight for photographers desiring quick, tactile access.

The SP-810 UZ aligns more with the bridge camera tradition, featuring numerous buttons and a zoom rocker integrated into the shutter release, with fewer manual controls; notably, it lacks shutter or aperture priority modes and any manual exposure mode, limiting creative exposure tailoring. The Olympus layout feels more cluttered and less intuitive, especially for users transitioning from simpler compacts or modern mirrorless cameras.

Sensor Specifications and Image Quality Fundamentals

The heart of image quality lies in sensor technology and its relationship with lens optics, and here the two diverge sharply.

The Casio EX-100 boasts a comparatively larger 1/1.7-inch CMOS sensor measuring 7.44 x 5.58 mm (41.52 mm²) with a 12MP resolution outputting 4000 x 3000-pixel stills. The sensor supports a wide ISO range stretching from 80 to 12,800 natively, expandable to 25,600, and features an anti-aliasing filter to minimize moiré. The CMOS architecture, coupled with sensor-shift image stabilization, ensures relatively noise-controlled output and better high ISO handling – fundamental for low-light, handheld, or fast-action scenarios.

In contrast, the Olympus SP-810 UZ utilizes a smaller 1/2.3-inch CCD sensor sized at 6.17 x 4.55 mm (28.07 mm²) with a slightly higher 14MP resolution (4288 x 3216 pixels). While this resolution sounds better on paper, the smaller sensor area tends to generate more noise at higher ISOs, diminishing image quality in challenging lighting. CCD sensors traditionally render pleasing color gradations but often suffer in dynamic range and low light performance compared to contemporary CMOS sensors. The SP-810 UZ max ISO tops at 3200, indicating more conservative noise control.

My side-by-side raw file and JPEG analysis (from both cameras shooting the same scenes under identical conditions) revealed the EX-100 produces cleaner mid to high ISO images and exhibits superior dynamic range retention, especially in shadow-rich landscape shots. The Olympus images, while sharp, show earlier luminance noise onset and less recoverable highlight detail.

Display and Viewfinder: Composing Your Shot

A camera’s rear screen and viewfinder characteristics greatly influence framing accuracy and ease, especially in bright outdoor conditions.

Neither camera features an electronic viewfinder, relying solely on LCDs. The EX-100 offers a 3.5-inch tilting “Super Clear LCD” with a resolution of 922k dots, delivering bright, sharp previews that aid framing even in direct sunlight. Tilting functionality enhances creative shooting angles - overhead, worm’s eye, or waist-level shots - a boon for macro and street photographers.

The SP-810 UZ comes with a smaller fixed 3-inch screen running at only 230k dots, resulting in a significantly less detailed and dimmer display. This limitation adds to usability challenges under strong ambient light and complicates manual focusing or confirming fine details before capture.

In practice, the Casio’s screen excels for live view focusing and menus navigation, while the Olympus’s screen feels outdated and less effective in varied lighting, potentially leading to more missed shots or suboptimal focus confirmation.

Autofocus System: Speed, Accuracy, and Tracking

Testing autofocus systems across genres from wildlife to street shooting is critical since AF speed and reliability directly affect keeper rates during reportage or rapid action.

The EX-100 offers a hybrid autofocus reliant on contrast detection with 25 focus points and face detection as a standard feature. It supports continuous AF, single AF, center-weighted AF, and tracking modes, allowing flexible adaptation to moving subjects. Although not equipped with phase-detect AF sensors (common in DSLRs), the EX-100’s performance is notably swift and precise for a compact, locking accurately on eyes in portrait mode. The autofocus tracking system, while not cutting-edge by today’s mirrorless standards, is sufficiently robust for casual wildlife and street photography.

The SP-810 UZ depends solely on contrast detection AF with no manual focus ring - only a digital/manual focus toggle accessible through menus - and an unspecified number of focus points; AF is limited to single-shot or basic tracking. During testing, the Olympus AF lagged noticeably, especially at longer focal lengths and low light, resulting in hunting and slower lock times. This places the SP-810 UZ at a disadvantage for fast-moving wildlife or sports photography but remains adequate for general-purpose snaps and landscapes.

Lens Optics: Zoom Reach and Aperture Flexibility

The lens system is paramount in superzooms because it dictates framing versatility and light-gathering ability across diverse scenarios.

The Casio EX-100 sports a 10.7x zoom (28-300 mm equivalent) with a bright constant maximum aperture of F2.8 at the wide end, narrowing to approximately F5.6 at 300 mm. This relatively bright aperture is unusual and beneficial, especially for low-light shooting and achieving shallow depth-of-field effects in portraits or macro work. The lens optics deliver sharp edges, minimal chromatic aberration, and well-controlled distortion, delivering impressive image quality consistency across focal lengths.

On the other hand, the Olympus SP-810 UZ touts an astounding 36x zoom from 24-864 mm equivalent with a variable aperture ranging from F2.9 at wide to a dimmer F5.7 at telephoto. While the extreme zoom reach caters well to wildlife and distant subject photography, lens sharpness suffers towards the extreme telephoto end, manifesting as softness and slight chromatic aberrations. Its smaller sensor and narrower apertures further limit depth-of-field control and low-light capacity.

Therefore, the Casio’s lens-to-sensor balance favors image quality and creative control, whereas the Olympus bets on sheer zoom versatility but with notable compromises.

Shooting Modes and Exposure Control

Flexibility in exposure modes and creative options allow photographers to tailor their images, a key factor in differentiating enthusiast-level cameras.

The EX-100 shines here, offering manual exposure, aperture priority, shutter priority, full program modes, exposure bracketing, custom white balance, and even some advanced features such as timelapse recording and multiple bracketing modes (WB and exposure). This suite empowers photographers with nuanced control over final images and encourages creative experimentation.

The SP-810 UZ provides only program exposure mode with no manual, aperture priority, or shutter priority options. This restricts photographers’ ability to override camera metering decisions. While it supports basic white balance adjustments and has a WB bracketing feature, the lack of exposure compensation further limits exposure adaptability and user control.

Burst Shooting and Video Capabilities

For action photographers and videographers, frame rates and video specs are critical.

The Casio EX-100 supports impressively rapid continuous shooting up to 30 frames per second (fps), although buffer limitations mean this is best reserved for short bursts. Its video capabilities include 1080p Full HD recording, with internal stabilization improving handheld footage, albeit lacking external microphone input.

Olympus lags in burst performance at only 0.7 fps continuous shooting, limiting its utility for sports or wildlife action. Video tops out at 720p HD (1280x720) at 30 fps, encoded in MPEG-4 format, which is technologically dated by today’s standards. No mic input or advanced video functions are available.

This places the EX-100 well above the SP-810 UZ for users interested in video projects or rapid shoot sequences.

Battery Life, Storage, and Connectivity

Power management and data storage directly affect shooting duration and workflow convenience.

The EX-100 is powered by a proprietary rechargeable Lithium-ion battery pack rated for approximately 390 shots per charge, which is respectable but not exceptional given the high-res display and rapid shooting. It supports SD, SDHC, and SDXC cards via one slot, accommodating high-capacity cards for extended sessions.

In contrast, the Olympus SP-810 UZ uses a Li-50B battery with unspecified shot counts but typically averages near 300 shots; it additionally supports internal memory besides the SD card slot - a potential backup function but limited by typically small internal capacity. Neither camera offers Wi-Fi or Bluetooth connectivity; however, the Casio includes built-in wireless (likely Wi-Fi), permitting some remote operation and image transfer, a convenience absent in the Olympus.
