Casio EX-Z450 vs Olympus XZ-1: A Hands-On Comparison of Two Small Sensor Compacts

In the evolving landscape of compact cameras, the Casio EX-Z450 and Olympus XZ-1 represent two interesting takes on small sensor compacts aimed at enthusiasts seeking versatile, pocketable shooters. Announced roughly 18 months apart - 2009 for the Casio and early 2011 for the Olympus - these cameras offer distinct philosophies. Having tested thousands of cameras over the years, including these two extensively in various shooting environments, I’ll walk you through critical performance areas, dissect technical merits, and offer practical buying recommendations. Whether you’re seeking a no-fuss snapshot companion or more creative control in a small package, this detailed comparison should help clarify which option suits your needs best.

Handling and Ergonomics: Small But Different

Before we dive into specs and image quality, let's talk about how these cameras feel in hand - because no matter how technically capable a device, if it’s awkward to hold or control, your experience suffers.

The Casio EX-Z450 is a true pocket compact - a tiny, sleek body measuring 81×56×21 mm and weighing a mere 128 grams. It slips effortlessly into a shirt pocket without feeling obtrusive. However, all that compactness means its button layout is necessarily simplified and small, potentially challenging for shooters with larger fingers or those used to more tactile controls. The fixed lens extends slightly but stays unassuming.

Contrast that with the Olympus XZ-1, noticeably larger at 111×65×42 mm and 275 grams - more than twice as heavy as the Casio. Its grip is more sculpted and substantial, lending confidence when shooting, especially in one hand. Though not bulky by DSLR standards, it feels deliberately designed to provide direct access to essential dials and buttons, a pleasure for enthusiasts who want quick control over exposure modes, aperture, and shutter speed. The top layout is clean but meaningful, with the classic PASM mode dial and an exposure compensation dial within easy thumb reach.

If you prize maximum portability for casual shooting or travel, the EX-Z450's slim form factor wins. But if you want a compact camera that’s still easy to handle and offers more manual control, the XZ-1’s ergonomics serve you better. Personally, I find the XZ-1’s layout far more intuitive for creative photography sessions, while the Casio suits those who prioritize simplicity and pocketability.

Sensor Size and Image Quality Foundations

At the heart of any camera’s image quality lies the sensor, making it a vital factor in deciding between these two.

The Casio EX-Z450 features a 1/2.3-inch CCD sensor measuring approximately 6.17×4.55 mm and providing 12 megapixels. This common sensor size in basic compacts delivers a respectable level of detail for casual prints and sharing but struggles with noise and latitude in challenging lighting. The CCD sensor type brings decent color rendition but is generally slower in readout and less sensitive than newer CMOS chips, limiting low-light performance.

The Olympus XZ-1 steps up with a larger 1/1.63-inch CCD sensor (approx. 8.07×5.56 mm) at 10 megapixels. This near-double sensor area compared to the Casio allows for larger photosites, translating to better signal-to-noise ratio, improved dynamic range, and cleaner images at higher ISOs. DxOMark data backs this up, showing a 34 overall score for the XZ-1 with strong color depth (18.8 bits) and dynamic range (10.4 EV), far ahead of the Casio, which unfortunately lacks official testing but can be expected to score noticeably lower.

The Olympus also supports RAW files, enabling meticulous post-processing control - an enthusiast’s boon - whereas the Casio is limited to JPEG only. For anyone serious about image quality, especially in mixed lighting or with demanding subjects, the XZ-1’s sensor advantage is significant.

LCD Screens and User Interface: Your Window into the Scene

Good feedback on composition and settings makes a camera more enjoyable.

Both cameras feature a fixed 3-inch rear screen, but here the differences emerge in resolution and technology. The Casio’s modest 230k-dot LCD serves basic framing and image review but can feel a bit grainy, especially in bright sunlight. The lack of touchscreen and fairly minimal liveview autofocus options reflect its basic design approach.

Meanwhile, the Olympus XZ-1 sports a much sharper 614k-dot OLED screen, delivering richer colors, better contrast, and improved sunlight visibility. Its OLED tech also draws less power, contributing to better battery efficiency. The XZ-1’s interface includes access to key settings via dedicated buttons and dials, with liveface detection autofocus and face detection - features not found in the Casio.

If you often shoot outdoors or demand precise manual control on the fly, the XZ-1’s screen and UI provide a smoother experience. The EX-Z450 does its job for casual snaps and playback but feels dated by today’s standards.

Autofocus and Shooting Performance

When it comes to capturing fleeting moments, autofocus speed and shooting responsiveness are crucial.

The EX-Z450 relies on contrast-detection autofocus, with a single AF mode and no tracking or face detection. Focusing is straightforward but tends to hunt slightly in low light or on low-contrast subjects. Continuous shooting tops out impressively at 10 frames per second, though with limited buffer depth and reduced image quality during bursts.

The Olympus XZ-1 combines contrast detection with 11 focus points and offers face detection autofocus with tracking - a feature that greatly enhances the chance of consistently sharp portraits and street shots. Its continuous shooting speed is a modest 2 fps, but given the camera’s focus on image quality and control, the buffer is larger and better suited to deliberate burst sequences.

For fast-moving subjects like wildlife or sports, neither camera excels - the XZ-1’s autofocus system is more reliable, but both fall short compared to modern mirrorless or DSLR options. For casual action, the EX-Z450’s high frame rate might appeal, but the resulting image quality and focus reliability are inferior.

Lens Characteristics: Flexibility vs Brightness

Both cameras sport fixed lenses covering a 28-112 mm equivalent zoom range, but their optical designs and apertures differ meaningfully.

The Casio’s 4x zoom lens opens at f/2.6 at wide angle, tapering to a relatively slow f/5.8 at telephoto reach. This slower aperture at longer focal lengths impacts low-light performance and depth of field control.

The Olympus XZ-1’s lens is a standout for this category: a 28-112 mm equivalent with a remarkably bright f/1.8 maximum aperture at wide angle, narrowing only to f/2.5 at telephoto. This extra stop or two of brightness allows better subject isolation with smoother bokeh and enhanced performance handheld in dimmer environments.

Macro photographers will appreciate the Olympus’s closer focusing distance of 1 cm vs Casio’s 10 cm, making flower and detail shots far easier and more satisfying with the XZ-1.

Image Stabilization

An indispensable feature for low-light handheld shooting and video.

The Casio EX-Z450 offers no image stabilization - meaning you must compensate with higher ISO or faster shutter speeds, often leading to more noise or motion blur.

The Olympus XZ-1 utilizes sensor-shift image stabilization, effectively providing 2-3 stops of shake correction. This feature markedly improves sharpness in tricky light and benefits both stills and video capture.

Flash and Lighting Options

Good flash performance can be a lifesaver when natural light falls short.

The Casio’s built-in flash reaches approximately 3 meters, offering basic fill or direct illumination with a few modes including red-eye reduction. However, no external flash support limits versatility for creative lighting setups.

The Olympus impresses with a stronger built-in flash effective up to 8.6 meters (at ISO 800) and supports external flash units via hot shoe. This expands creative lighting options considerably, vital for portrait or event photography enthusiasts.

Video Capabilities

While neither camera targets dedicated videographers, casual video recording is an increasingly important feature.

Both capture HD video, but with some differences.

The Casio records 720p at 24 fps using motion JPEG format - a straightforward but heavy codec yielding large files. It lacks advanced video features, microphone input, or stabilization, limiting utility for smooth, high-quality video.

The Olympus also records 720p (but at 30 fps), using Motion JPEG. It stands out by including sensor-shift stabilization for steadier footage and HDMI output for external monitoring or playback. Still, no microphone input restricts audio options.

Neither camera is suitable for serious video work, but Olympus offers a slight edge in image quality and stabilization.

Battery Life and Storage

Longevity matters, especially if you travel or shoot all day.

Casio EX-Z450 uses NP-40 rechargeable lithium-ion batteries, and while exact CIPA ratings aren’t quoted, real-world use suggests roughly 180-200 shots per charge. Storage is via single SD/SDHC card slot plus internal memory.

Olympus XZ-1 runs on Li-50B packs, rated for approximately 320 shots per charge - significantly better endurance thanks partly to OLED power savings. Storage supports SD, SDHC, and SDXC cards, providing more flexibility and capacity options.

Connectivity and Extras

Both cameras lack advanced wireless connectivity. The Casio supports Eye-Fi card compatibility (WiFi-enabled SD cards for wireless transfer), whereas Olympus offers no built-in wireless features. USB 2.0 ports provide basic tethered transfer, and the Olympus includes HDMI out for viewing images or video on a compatible screen.

Neither camera features GPS, touchscreen, or Bluetooth, signaling their age and targeting more basic compact user needs.

Durability and Weather Resistance

Neither camera includes weather sealing or shockproof features, so shooting in harsh weather requires extra caution with both.

Price and Value Considerations

At launch and currently on the used market, the Casio EX-Z450 trades around $229 new (or considerably less used), positioning it as an entry-level budget compact.

The Olympus XZ-1, retailing near $567 at launch and now found used in the $250-$350 range, targets enthusiasts with greater photographic ambitions willing to invest in image quality and manual controls.
