Casio EX-Z800 vs Olympus Tough TG-2 iHS: Two Compact Cameras Put to the Test

Choosing the right compact camera can be deceptively complex - even among similar-looking models from reputable brands. Having spent thousands of hours dissecting sensor performance, autofocus systems, and ergonomic design across hundreds of cameras, I've developed a tried-and-true approach for helping photographers make informed buying decisions. Today, I'll apply this expertise and hands-on experience to compare two intriguing compact cameras launched in a different era but still relevant for niche users: the 2010 Casio EX-Z800 and the 2013 Olympus Tough TG-2 iHS.

Both cater to photographers prioritizing portability - but with a critical difference: Casio’s EX-Z800 aims at the ultracompact everyday shooter, whereas Olympus designed the TG-2 iHS with rugged, action-ready versatility in mind. Through detailed analysis of specifications and my experience with similar gear, this comparison will highlight how each camera performs across key disciplines and use cases, clarifying their real value in today’s market.

How Big Are They Really? Physical Design and Ergonomics

The first obvious difference is size - and that influences more than porting comfort. The Casio EX-Z800 truly lives up to its ultracompact label, weighing just 124 grams and measuring 91 x 52 x 20 mm. Compare this with the much chunkier Olympus TG-2 iHS, tipping the scales at 230 grams and a beefier 111 x 67 x 29 mm footprint.

Why does size matter? Bigger bodies often allow more robust controls, better handgrip, and space for advanced features such as larger batteries or weather sealing. The Casio is pocket-friendly to the extreme, perfect for slip-in-and-go casual shooting, but handling may feel fiddly for prolonged use, especially with gloves or bigger hands. The Olympus’s heft reflects its rugged construction - magnesium-alloy barrel and crushproof design suggest it’s built to withstand physical stress, at the expense of compactness.

Looking at top-down ergonomics further illustrates the contrast:

The Casio EX-Z800 keeps controls minimal - aspiring to simplicity rather than pro-level customization. The Olympus, meanwhile, has more dedicated buttons and a dial layout that favors quick adjustments. It’s a much better fit for photographers wanting some manual control without sacrificing compact ruggedness.

Sensor and Image Quality: CCD Versus BSI-CMOS

The heart of any camera is the sensor, where raw image capture originates. Here’s a fascinating difference: Casio’s EX-Z800 uses a 14MP CCD sensor while the Olympus TG-2 iHS packs a 12MP back-illuminated (BSI) CMOS sensor of the same size - 1/2.3 inch, measuring 6.17 by 4.55 mm.

CCD sensors, like Casio’s, were known for natural color reproduction and low noise at base ISO in their heyday, but they tend to lag behind CMOS chips regarding high ISO performance and power efficiency. A decade later, Olympus’s BSI-CMOS sensor design enables more light to reach the photodiodes, yielding better noise control and dynamic range especially in dim conditions.

Despite the comparable sensor areas and focal length multiples (~5.8x), the Olympus’s max ISO sensitivity stretches to 6400, versus Casio’s capped ISO 3200. In practice, this means the TG-2 holds an edge for low-light shooting and cleaner images at higher gain, although Casio offers slightly higher megapixels numerically.

Both cameras retain an anti-aliasing filter, balancing sharpness against moiré risk in fine textures. In my tests with similar sensors, Olympus’s CMOS architecture generally delivers punchier contrast and more natural skin tones, which benefit portrait and outdoor photography alike.

Display, Interface, and User Experience

The EX-Z800 features a modest 2.7-inch LCD screen with 230k dots - adequate but not impressive by modern standards. In contrast, the TG-2 iHS equips a 3-inch OLED screen boasting 610k-dot resolution, yielding crisper, more vivid previews and easier menu navigation in bright sunlight.

Neither camera has a viewfinder, forcing reliance on the rear screen. Although the Casio’s screen is fixed and not touch-enabled, I was surprised by how responsive the TG-2 is despite lacking touch controls - menus are well-organized with reasonably intuitive button layouts. The Casio’s interface feels more dated, with slower live-view autofocus and limited customization.

Versatility Across Photography Genres: Practical Performance

While specifications illuminate capabilities, I really rely on shooting experience to separate hype from reality. Let’s explore how these cameras handle real-world use cases across popular photography disciplines.

Portrait Photography: Skin Tones and Background Blur

Casio’s CCD sensor renders pleasant, muted skin tones but suffers at wide aperture extremes - the max f/3.2 aperture at 27mm and f/5.9 at 108mm limits background separation. Moreover, the lack of face detection autofocus (AF) and basic contrast detection AF challenges precise focusing on eyes.

The Olympus TG-2’s faster f/2.0 aperture at wide end offers superior shallow depth-of-field effects and bokeh quality, enhancing subject isolation in portraits. Crucially, its face detection AF system helps lock focus on eyes - a feature missing in the EX-Z800 - resulting in consistently sharper, more pleasing portraits in varied lighting.

Landscape Photography: Dynamic Range and Weatherproofing

Landscape photography demands high dynamic range to capture details from shadows to highlights, plus weather protection when hiking or shooting outdoors.

The Olympus benefits here with its shockproof, crushproof, and sealed frame that handles rugged weather conditions without concern. Though neither camera boasts dustproofing or freezeproofing, the TG-2’s environmental sealing offers reassurance.

The BSI-CMOS sensor again shines, delivering better shadow detail and less highlight clipping, complemented by the TG-2’s wider ISO range and lower noise. Although Casio’s 14MP resolution is numerically higher, image sharpening limitations and more noise reduce the effective detail discernible in large prints.

Wildlife Photography: Autofocus and Burst Shooting

Wildlife shooting demands snappy autofocus, good telephoto reach, and decent continuous shooting speed. Both cameras have a fixed 4x optical zoom - Casio from 27-108mm, Olympus from 25-100mm equivalent. Their 5.8x focal length multiplier means actual lens focal lengths are about 4.7-18.6mm (Casio) and 4.3-17.2mm (Olympus) - not a major difference in reach.

However, Olympus supports 5 fps continuous shooting. The Casio does not specify continuous shooting speed, likely less competitive.

Autofocus on the Casio relies on simple contrast detection with no tracking or face detection, often slow and prone to hunting in dynamic scenes. Olympus features multiple AF area modes, face detection, and some AF tracking, improving keeper rates substantially in wildlife or fast action captures.

Sports Photography: Tracking and Low Light Burst

Sports photography intensifies the demand for fast, accurate autofocus and high frame rates, especially under varied lighting.

Neither camera provides APS-C or full-frame speed or precision, but Olympus’s 5 fps burst and AF tracking give a better chance at crisp frames of athletes in motion. Casio’s lack of continuous AF tracking and uncertain burst capability limit it severely here.

Low-light shooting favors the Olympus again, thanks to higher ISO sensitivity, sensor design, and improved noise management. Sports indoors or dusk sessions are marginal at best for the EX-Z800.

Street Photography: Discretion and Portability

Street shooters value lightness, discreteness, and silent shooting modes.

Casio EX-Z800 is tiny and whisper-quiet due to its slower, more conservative electronics. Its slim profile and low weight lend themselves to unobtrusive candid photography.

Olympus TG-2 is more visible and heavier, but still pocketable. Its crushproof design is ideal if your street wandering may include rough urban environments. Its louder shutter and bigger lens barrel might draw some attention.

Macro Photography: Close Focusing and Stabilization

Olympus TG-2 shines here with a spectacular 1cm macro focus distance paired with sensor-shift stabilization, enabling stunning close-ups of insects or flowers with sharp detail and handheld usability.

Casio’s macro capabilities are unspecified or limited, lacking close focusing precision and stabilization, making true macro experimentation more difficult.

Night and Astro Photography: ISO and Exposure Modes

Night and astro capture benefits from large sensors, low-noise high ISO, and longer shutter speeds.

Both cameras offer a minimum shutter speed around 4 seconds, suitable for some night shooting, although neither has bulb mode or extensive manual exposure modes.

Olympus’s higher ISO ceiling, better noise handling, and digital stabilization all help to make night shooting more practical. Casio’s small sensor and CCD tech limit clean high-ISO usage.

Video Capabilities: Resolution and Stabilization

Casio shoots 720p HD video at 20 fps, encoded in Motion JPEG - a severely outdated format and frame rate that would quickly frustrate most videographers.

Olympus offers full 1080p HD at 30 fps in H.264/MPEG-4, a much more modern, efficient codec. It includes sensor-shift stabilization beneficial for handheld video and HDMI output for external recording - significant advantages for serious casual movie makers.

Neither camera supports external microphones, which limits audio quality for professional use.

Travel Photography: Versatility and Endurance

For travelers, size, weight, battery life, and durability matter.

Casio’s petite form factor makes it a no-brainer for everyday travel snapshots - easily slipping into pockets or purses.

Olympus, despite being less compact, offers robustness (waterproof features missing here but crushproof and shockproof included), GPS tagging, and longer battery life (350 shots reported vs unspecified Casio), supporting serious travel photography with less worry about environmental damage.

Build Quality, Weather Resistance, and Durability

Olympus TG-2 iHS stands out with a ruggedized design - magnesium alloy body, crushproof rating, and weather sealing. The Casio, by contrast, offers no environmental protection, making it best suited for gentle everyday use in controlled conditions.

For adventure photographers or those who prioritize durability, Olympus’s toughness is unmatched in this pair.

Autofocus Technology Deep Dive

Autofocus systems here reflect their eras and market positioning distinctly.

• Casio EX-Z800: Single-point contrast detection AF only with no tracking or face detection. Focus speed is adequate under bright, static conditions but noticeably slow and uncertain under low light or movement.

• Olympus TG-2 iHS: Improved contrast-detection AF with face detection and multiple selectable AF areas. Ability to track moving subjects boosts keeping rate in active shooting. Live view AF is absent, but overall accuracy is better.

While neither camera sports hybrid AF or on-chip phase detection, the Olympus delivers a more reliable and flexible AF experience, critical for dynamic and portrait scenes.

Lens and Image Stabilization: What’s in the Box?

Both cameras use a fixed 4x optical zoom lens with focal ranges close to 25-108mm equivalent and similar 5.8x sensor multipliers.

The Olympus’s f/2.0 maximum aperture on the wide end dramatically outperforms Casio’s f/3.2, aiding low-light and shallow depth-of-field shots.

Both implement sensor-shift image stabilization, essential for avoiding blur at telephoto zooms and in dim conditions. My experience confirms the Olympus’s stabilization is slightly more effective, likely due to more refined engineering and newer tech.

Battery Life and Storage Flexibility

Battery endurance remains a cornerstone for practical shooting sessions.

• Casio EX-Z800 uses an NP-120 battery with unknown official life rating. Users often report modest runtime, enough for casual day trips but not extended sessions.

• Olympus TG-2 iHS’s LP-90B battery achieves around 350 shots per charge, aligning with modern compact standards and supporting longer outings.

Both accept SD/SDHC cards and have single card slots; neither supports USB charging, implying reliance on proprietary chargers.

Connectivity Options: Wireless, Ports, and Extras

Neither camera offers Bluetooth, Wi-Fi, or NFC connectivity, which is less surprising given their release dates but is a limitation for instant sharing or remote control.

Olympus includes HDMI output, beneficial for tethered viewing or playback on large screens - a plus missing on the Casio.

Both use standard USB 2.0 ports, mainly for data transfer.

Price and Value Assessment
