Casio EX-Z450 vs Ricoh WG-4: A Hands-On Comparison of Compact Cameras with a Twist

In a photography world dominated by mirrorless marvels and hefty DSLRs, sometimes it’s refreshing to look back - or sideways - at compact cameras that quietly hold their own, especially for casual enthusiasts or specific niche uses. Today I’m diving deep into two very different iterations of compact cameras from yesteryear: the 2009 Casio EX-Z450 and the 2014 ruggedized Ricoh WG-4. While they both cater to the ‘small sensor compact’ category, they couldn’t be more different in philosophy, build, and use-case focus.

Having spent years testing and comparing cameras across various genres, I find that these models provide a fascinating contrast: the EX-Z450 epitomizes the late-2000s pocket shooter mentality - simple, modestly specced, affordable - while the WG-4 targets adventurous photographers seeking robustness and more contemporary features in a compact body.

Let’s explore their practical merits, technological distinctions, and how they handle across photography genres and scenarios - helping you decide if either might still deserve a spot in your gear bag or just curiosity in your tech archives.

First Impressions: Size, Build, and Handling

Starting with the obvious: the Casio EX-Z450 and Ricoh WG-4 are both compact cameras but in very different ways. The EX-Z450 is delightfully pocketable, weighing just 128g and measuring 81×56×21 mm - barely noticeable in a coat pocket (great for street or casual travel photography). The Ricoh WG-4, on the other hand, clocks in heavier and chunkier at 230g and 124×64×33 mm, reflecting its ruggedized ethos.

Handling the EX-Z450 feels almost like holding a high-grade point-and-shoot from its era - plastic build, minimal grip, very light but somewhat “toy-like.” The WG-4 impresses immediately with its robust housing, textured grip, and reassuring heft - designed to handle shocks, water, dust, and even freezing temperatures.

Both feature a similar small footprint but serve different priorities. The EX-Z450 aims for ultra-portability; the WG-4 delivers durability and all-weather readiness without sacrificing too much compactness.

Controls on the EX-Z450 are sparse - no dedicated dials or extensive buttons, just the basics. It lacks manual exposure modes and advanced control, which can feel limiting to enthusiasts seeking creative input. The Ricoh WG-4, however, upgrades the tactile experience slightly, offering shutter priority mode and more comprehensive control buttons - even if no full manual exposure mode is present. The layout is better for quick adjustments outdoors, though small buttons still require fiddling with gloves.

For ergonomics enthusiasts, the WG-4 wins hands down in terms of grip quality and user confidence to shoot with in variable conditions, whereas the EX-Z450 excels at stealth and convenience.

Sensor and Image Quality: Small Sensors, Big Compromises?

Now, onto the heart of any camera’s imaging capability: the sensor. Both cameras use a 1/2.3" sensor, which is tiny by today’s mirrorless standards but standard for compact cameras of their day. Technically, both feature sensors of the same physical size (6.17×4.55 mm), but key differences emerge in sensor technology and resolution.

The EX-Z450 employs a 12-megapixel CCD sensor - common during its launch era - which can produce decent images in good light but tends to struggle with noise and limited dynamic range, especially as ISO climbs. Its maximum native ISO tops out at 1600, but expect noise to degrade image quality significantly beyond ISO 400 in practice.

The Ricoh WG-4 upgrades to a 16-megapixel BSI-CMOS sensor, a more modern design delivering better light sensitivity and efficiency. This technology improvement offers superior high-ISO performance (max ISO 6400), better dynamic range, and generally cleaner images - even if tiny sensor limitations remain.

In practical shooting, the Ricoh’s sensor provides noticeably sharper images with better color fidelity and less noise across various lighting conditions. The EX-Z450’s images feel softer and less defined, especially in shadows or dim scenes.

LCD Screen and User Interface: Peering into the Viewfinder Void

Neither camera features an optical or electronic viewfinder, relying solely on their rear LCD for composing and reviewing shots.

The EX-Z450 sports a 3” screen with a modest 230k-dot resolution, resulting in a grainy and somewhat dim preview that's tricky under bright sunlight. On the other hand, the WG-4’s 3” TFT LCD boasts 460k-dot resolution, offering a much clearer, brighter image with richer colors - great for outdoor use.

User interface on both models remains relatively basic compared to modern standards, but Ricoh’s UI is snappier with a more logical menu layout. Casio’s menus feel dated and sluggish, affecting the overall shooting experience.

Diving Into Autofocus and Shooting Modes

Autofocus performance is crucial, especially for fast-paced subjects like wildlife or sports. Here the differences reflect their market focus vividly.

Casio EX-Z450

• Contrast-detection AF only
• Single AF mode
• No face detection or tracking
• Limited AF points (none specified), likely center-weighted
• No continuous autofocus or tracking

Ricoh WG-4

• Contrast-detection AF with 9 points and multi-area selection
• Face detection supported
• Continuous autofocus and tracking modes
• Center-weighted AF available

In the field, the WG-4’s autofocus system is noticeably more adept at locking focus quickly and tracking moving subjects, although it’s not blazing fast compared to modern CSCs or DSLRs. The EX-Z450 struggles outside bright, static scenarios - hunting for focus in low-contrast or dim environments, making it less suited for action or wildlife photography.

With 2 fps burst for WG-4 (continuous AF) vs 10 fps for EX-Z450 (no continuous AF), the Casio's continuous shooting speed is surprisingly higher, but it’s less practical without tracking autofocus - mostly good for capturing rapid shots of static or slow subjects.

Lens Specs: Zoom, Macro, and Aperture

Both cameras have fixed zoom lenses with similar 4× optical zoom range but slightly different focal lengths and apertures:

• Casio EX-Z450: 28-112mm equivalent, f/2.6-5.8 aperture
• Ricoh WG-4: 25-100mm equivalent, f/2.0-4.9 aperture

Ricoh’s lens is faster at the wide end (f/2.0 vs f/2.6) and maintains a brighter aperture across the zoom than the Casio, allowing better low-light capability and subject isolation. Its macro focus distance is impressively close - down to 1 cm - versus Casio’s 10 cm minimum, lending the WG-4 superior macro photography potential.

In practice, WG-4 delivers punchier bokeh and sharper images across its zoom range, with less vignetting. However, neither can rival interchangeable lens systems for depth or versatility.

Durability and Outdoor Use: The WG-4’s Wild Card

If you’ve ever dropped or launched a camera into a puddle (guilty here), durability matters.

The EX-Z450 is a typical compact - not weather sealed, not shock or freeze resistant, just meant for careful handling indoors or in controlled conditions.

The Ricoh WG-4 is a tank disguised as a camera - waterproof to 14m, shockproof from 2m drops, crushproof to 100 kgf, and freezeproof to -10°C. For outdoor photography - especially landscape, wildlife, adventure, or travel - this ruggedization is a massive plus.
