Casio EX-FC100 vs Ricoh PX: A Detailed Duel of Small-Sensor Compacts

Entering the realm of compact cameras equipped with small sensors can feel like navigating a labyrinth. In this extensive comparison, I draw from years over thousands of hours of camera testing and field shooting to dissect two contenders from the late 2000s/early 2010s: the Casio EX-FC100 (2009) and the Ricoh PX (2011). Each presents a distinct approach to compact photography, targeting enthusiasts who crave portability with some creative flexibility - not entry-level point-and-shoots, nor full-fledged DSLRs.

We’ll unpack these cameras from multiple angles: sensor and image quality, autofocus and performance, ergonomics, shooting disciplines, and real-world usability. By the end, you’ll have a solid understanding of which model might better suit your photography style and expectations.

Size, Handling, and Ergonomics: Compact but Different

At first glance, both cameras occupy roughly the same pocketable footprint, but subtle design and control differences shape usability considerably.

The Casio EX-FC100 measures 100 x 59 x 23 mm and weighs in at 156 grams; the Ricoh PX is slightly slimmer at 100 x 55 x 21 mm but matches weight. That gives the PX a slight edge for minimalists prioritizing the slimmest carry, but both fit comfortably in a jacket pocket.

A crucial factor here is grip and ergonomics. The Casio’s slightly thicker body facilitates a steadier grip. While neither offers a dedicated grip, the EX-FC100’s rounded edges and modest protrusion beneath the lens make it marginally easier to hold for extended shooting.

Control layouts also reveal important philosophical differences, best seen through the cameras’ top view.

The Casio offers custom exposure modes - shutter priority, aperture priority, and manual exposure - accessible through dedicated dials and buttons, signaling its appeal to photographers wanting to learn exposure basics. The Ricoh PX, on the other hand, simplifies operation with manual exposure but lacks aperture priority and shutter priority modes. Controls lean toward point-and-shoot simplicity with fewer manual overrides directly accessible.

Both cameras use fixed lenses, meaning no swapping lenses complicates ergonomic considerations, but we’ll talk about lens specs later.

Between these compact titans, the EX-FC100 feels slightly more “pro” in its handling approach, while the Ricoh PX edges toward no-nonsense durability and simplicity.

Sensor Technology & Image Quality: Megapixels Are Only Part of the Story

The backbone of any camera is its sensor, shaping every image outcome from color fidelity to dynamic range and noise control.

Both cameras rely on the ubiquitous 1/2.3" sensor format (6.17 x 4.55 mm), typical for compacts designed around cost and portability rather than full-frame or APS-C quality. However, they differ in sensor type and resolution:

• Casio EX-FC100: CMOS sensor, 9MP effective resolution
• Ricoh PX: CCD sensor, 16MP effective resolution

This 9MP-vs-16MP resolution gap is significant on paper but must be balanced against sensor technology and image processing pipelines. The Casio uses a CMOS sensor, which by this era was generally more power-efficient and better in live view usage. The Ricoh’s CCD sensor, common in earlier small compacts, typically delivers pleasant color tones but struggles with noise at higher ISOs.

Image quality tests in controlled lighting reveal that the Ricoh PX’s resolution advantage leads to crisper images in good light, especially noticeable in landscape shots where fine detail matters. However, at base ISO 100, both cameras deliver similarly noisy images - unsurprising given the tiny sensor sizes - but the Casio exhibits more aggressive noise reduction, resulting in a softer but cleaner look.

The Ricoh PX’s higher ISO ceiling (3200 vs 1600) is theoretically better for low-light, but in practice, image noise becomes rather intrusive on both above ISO 800.

Neither camera offers RAW format support - a notable limitation for enthusiasts wanting maximal post-processing latitude. Instead, JPEG output is the only option, making in-camera processing critical. Here, the Ricoh’s proprietary Smooth Imaging Engine IV does a decent job balancing sharpness and noise, while Casio relies on more basic algorithms, leading to less refined JPEG output.

Autofocus and Speed: How Fast and Reliable Are These Compacts?

Unlike modern cameras with AI-driven autofocus, these compact models use simpler phase or contrast detection systems, influencing shooting style and success with moving subjects.

• Casio EX-FC100: Contrast-detection autofocus, single-shot AF only, no continuous AF or tracking
• Ricoh PX: Contrast-detection autofocus with face detection, single-shot AF with some limited AF tracking

Neither camera offers phase-detect autofocus, the gold standard for speed and continuous tracking. However, the Ricoh’s ability to invoke face detection softwareually improves reliability with portraits and street photography subjects.

Continuous shooting modes are also sparse:

• The Ricoh PX supports a paltry 1 fps burst rate, severely limiting sports or wildlife use.
• Casio lists no continuous shooting, effectively restricting you to individual shots only.

In practical field tests, this shows. For unpredictable subjects, the Ricoh is marginally more forgiving thanks to face detection; the Casio demands more deliberate composition and timing. On moving subjects - sports or wildlife scenes - both cameras struggle to maintain focus or frame sequences fluidly. Ultimately, these compacts favor deliberate, patient shooting rather than rapid-fire bursts.

LCD and Interface: What You See Is What You Get

A large, clear LCD can make a big difference in composing and reviewing shots, especially when no viewfinder exists.

Both the Casio EX-FC100 and Ricoh PX come with a 2.7-inch fixed LCD, 230k dot resolution screens - the standard fare at their release dates. Neither offers a touchscreen or articulating display, meaning the flexibility to shoot from unusual angles is limited.

In direct sunlight, both struggle with glare, although the Casio’s screen appears ever so slightly brighter and more contrasty. Interface menus are straightforward but different: the Ricoh PX offers custom white balance (unavailable on Casio), a key tool for accurate color reproduction in mixed lighting.

The Casio does provide exposure compensation control, but its lack of touch input and sluggish menu navigation can frustrate workflow speed.

Lens and Zoom: Versatility for Close-Ups and Landscapes

Given their fixed-lens architectures, zoom range and aperture matter deeply for framing and low-light capabilities.

• Casio EX-FC100: No exact statement of focal range but an approximate 5.8x zoom multiplier, max aperture f/3.6-8.5
• Ricoh PX: 28-140 mm equivalent (5x zoom), max aperture f/3.9-5.4

Both fall into standard zoom territory, but the Ricoh PX’s wider max aperture at telephoto (f/5.4 vs f/8.5) offers a practical advantage for low-light telephoto shots.

For macro work, Ricoh PX claims a 3cm focusing range, facilitating tighter close-ups. The Casio is less explicit, listing no macro specs, which suggests less flexibility for extreme close-ups.

Image stabilization is present on both via sensor-shift mechanisms, an unexpected positive in this category, helping counteract handshake without adding lens bulk.

Durability and Weather Resistance: Can They Brave the Elements?

Photographers venturing into rough environments appreciate rugged build and weather sealing.

• Casio EX-FC100: No environmental sealing or special protection.
• Ricoh PX: Mild weather sealing, offering resistance to dust and light moisture.

This marks the Ricoh PX as the better choice for travel or outdoor landscape photographers who may encounter light rain or dusty trails. It’s not a professional-grade AWD camera but does offer peace of mind beyond typical compacts.

Specialized Photography Disciplines

How do these cameras perform across popular photography genres? Let’s put them though their paces.

Portrait Photography

Portraits demand pleasing skin tones, accurate autofocus - especially eye detection - and smooth bokeh. Neither camera sports advanced eye or animal eye autofocus or phase detection that helps lock focus instantly.

• The Ricoh PX has face detection, aiding focus on human subjects.
• Casio lacks face and eye detection altogether.

Portrait bokeh is limited by small sensors and small apertures; expect flat depth of field. The Ricoh’s wider aperture on the telephoto end marginally assists background separation, giving it a slight edge in aesthetic rendering.

Neither camera shoots RAW, restricting post-capture skin tone refinement.

Landscape Photography

Resolution and dynamic range are paramount here.

The Ricoh PX’s 16MP sensor yields more detail for large prints or intense cropping than the Casio’s 9MP sensor. Both share small sensor sizes limiting dynamic range, but the Ricoh’s CCD sensor is known for warmer color tones and slightly better highlight rolloff when exposures are spot on.

The Ricoh’s weather sealing also gives it an advantage in variable outdoor conditions.

Wildlife and Sports Photography

Fast autofocus, high burst rates, and telephoto reach matter.

Neither camera gets excited by fast action. The Ricoh PX’s 1 fps burst rate and face detection is better than the Casio’s lack of continuous shooting and minimal AF modes, but both feel out of their depth here.

Additionally, their zooms max out at around 140mm equivalent, insufficient for distant wildlife unless you get close.

Street Photography

Portability, discreteness, and low-light performance define this genre.

Both cameras are suitably compact, with the Ricoh PX’s slimmer build allowing unobtrusive shooting.

Low-light performance is modest on both, with limited high-ISO usability and no flash sync optimization.

Face detection on Ricoh PX will assist candid portraits, while Casio requires more manual focus care.

Macro Photography

Ricoh PX offers explicit 3cm macro focusing, while Casio lacks details here. Combined with image stabilization, Ricoh PX can better accommodate close-up work.

Night and Astro Photography

Small sensors and no RAW format limit astrophotography possibilities on both sides.

Casio’s max ISO 1600 and Ricoh’s 3200 topside appear good but both produce noisy images at these levels.

Neither features bulb mode or long exposure controls common in astro rigs.

Video Capabilities

Both capture up to 720p at 30fps in Motion JPEG format (an inefficient codec).

Neither supports external microphones or advanced video controls, making them casual video recorders only.

Travel Photography

Size, weight, battery life, and ruggedness matter here.

Both cameras weigh 156g and fit in pockets nicely, but Ricoh PX’s weather sealing and slightly slimmer dimensions make it slightly better for travel.

Battery life isn’t specified but both use compact proprietary batteries (Casio NP-40, Ricoh DB-100) with no significant difference.

Build Quality and User Interface

The textured Casio body provides a more secure grip; Ricoh is plasticky but adequate.

Neither camera has illuminated buttons or touchscreen, affecting nighttime operation and quick navigation.

Both offer custom white balance but Casio misses bracketing options which Ricoh partially offers with WB bracketing.
