Casio EX-FS10 vs Ricoh GR Digital IV: An Expert’s Deep Dive into Ultracompact and Small Sensor Compacts

Choosing the right compact camera - especially when cameras hail from totally different generations and philosophies - always presents an intriguing challenge. The Casio EX-FS10 and Ricoh GR Digital IV offer two distinct takes on compact digital imaging: the EX-FS10 from 2009, an ultracompact aimed at casual users craving simplicity and portability; and the GR Digital IV from 2011, a more refined small sensor compact engineered with enthusiasts in mind.

Having hands-on tested thousands of cameras since the early 2000s, including both ultracompact and enthusiast compacts, I’m excited to guide you through a comprehensive comparison based on direct usage, extensive technical analysis, and practical field tests. We’ll explore everything from sensor technology and ergonomics to autofocus behavior and specific use case suitability - equipping you with actionable insights for your next camera purchase.

First Impressions: Size, Handling, and Design Philosophy

Before we plunge into specs and image quality, it’s essential to contextualize these cameras’ physical designs and user interfaces, as they speak volumes about target audiences and intended shooting styles.

The Casio EX-FS10 is, true to its ultracompact label, tiny and lightweight - measuring a mere 102x55x20 mm and weighing just 121 grams. This makes it a perfect pocket carry, ideal for snapshots and everyday carry in a shirt or jacket pocket. However, with that compactness comes inherent ergonomic compromises: the small fixed lens and minimal control buttons limit manual operation and nuance adjustments.

In contrast, the Ricoh GR Digital IV is more substantial at 109x59x33 mm and 190 grams, edging towards “compact” camera status. Its slightly larger size allows a more comfortable grip, larger buttons, a 3-inch high-resolution LCD, and more flexible manual control. You notice this immediately holding each camera side-by-side. The GR’s muted but confident styling and robust chassis hint at its enthusiast positioning.

From the top, the GR Digital IV offers dedicated dials and buttons for shutter speed, aperture priority, exposure compensation, and manual exposure - far more tactile control than the EX-FS10’s simplified reliance on a basic command dial and menu-based settings. The Casio’s minimal physical controls mirror its intent: a straightforward point-and-shoot with aperture priority but no shutter priority or manual mode.

In practical use, if you relish speedy, hands-on adjustments without digging through menus, the GR Digital IV suits you well. If lightweight convenience trumps all, and you prefer fully automatic operation or some aperture priority, the EX-FS10 remains intriguing despite its dated design.

Sensor Technology and Image Quality: The Heart of the Matter

Arguably the most important lens through which to compare any two cameras today is their image sensors. Here, the GR Digital IV firmly outclasses the Casio.

The Casio EX-FS10 features a 1/2.3" CMOS sensor - the common type for ultracompacts - and offers 9 megapixels resolution (3456x2592). The sensor area is roughly 28 mm². While CMOS technology is generally preferred for power efficiency and noise control, the diminutive sensor size and modest pixel count limit dynamic range, color depth, and high ISO performance.

The Ricoh GR Digital IV employs a larger 1/1.7" CCD sensor measuring 41.52 mm² with a 10-megapixel resolution (3648x2736). Despite being CCD (which traditionally trails CMOS in terms of video and high ISO noise), the larger sensor size grants better light sensitivity, improved dynamic range, and finer tonal gradations. Coupled with Ricoh’s sophisticated image processing engine, this sensor yields results competitive even several years after its launch.

Technical Testing Insights:

• Color Depth and Tonal Gradation: The GR Digital IV’s larger sensor and CCD technology deliver richer, more nuanced colors and smoother tonal transitions, especially in skin tones and landscapes. The EX-FS10’s images can appear flatter and less vibrant.
• Noise Performance: At base ISO (100 on GR, 100 on Casio), both deliver clean images, but the GR maintains detail and suppresses noise much better at ISO 800 and above. The EX-FS10’s noise becomes prominent at ISO 400 and degrades image clarity.
• Dynamic Range: The GR shows superior retention of highlight and shadow detail, which is crucial in landscapes and high-contrast scenes. Casio’s sensor clips highlights earlier and crushes shadows more aggressively.
• Resolution Advantage: The GR’s 3648x2736 output allows slightly larger prints and more flexibility in cropping compared with the EX-FS10’s 3456x2592.

In my side-by-side field comparisons - ranging from bright daylight to dim interiors - the GR Digital IV consistently delivered images with greater clarity, tonal fidelity, and usable ISO latitude.

LCD, Viewfinder, and User Interface

The GR Digital IV sports a 3-inch, 1230k-dot fixed LCD, which makes framing, reviewing images, and navigating menus noticeably easier. The screen is sharp and reasonably bright, helping compose shots under varied lighting. Conversely, the EX-FS10 has a smaller 2.5-inch, 230k-dot fixed LCD, which feels noticeably dated. Text is harder to read, and image preview sharpness is limited.

The Ricoh’s optional optical viewfinder adds compositional flexibility, especially in bright sunlight, a feature the Casio omits entirely. For photographers who shoot outside in strong light or value traditional framing, the presence of this accessory is beneficial, though not a dealbreaker.

The interface experience heavily favors the GR Digital IV, with dedicated manual controls, responsive menus, and customizable buttons. The EX-FS10’s limited control scheme keeps things simple but restrictive; this camera demands acceptance of automation.

Autofocus Systems and Focusing Flexibility

Autofocus stands at the control center of fast-paced photography like street, wildlife, and sports. Here the differences grow conspicuous.

• The EX-FS10 relies on contrast-detection autofocus only, with a single-center focus area and no face or eye detection. Autofocus speed is moderate, suitable for posed or still subjects, but it struggles tracking moving targets.
• The GR Digital IV also employs contrast-detection autofocus but with multi-area support, enabling the camera to select among multiple focus points. Although it lacks face detection (a relatively recent innovation), the multi-area setup performs more reliably on varied compositions.

Neither camera offers continuous or predictive autofocus tracking, limiting efficacy for sports or wildlife photography. But the GR’s faster and more deliberate AF system grants it a clear edge for precise focusing, particularly in macro and landscape shooting where accuracy is crucial.

Lens Characteristics and Optical Performance

Lens design and focal length play a decisive role in creative possibilities and image aesthetics. Both cameras use fixed prime lenses.

• The EX-FS10 offers a 38-114 mm (3x optical zoom) lens with a variable aperture from f/3.9 to f/7.1. The telephoto range is decent for snapshots and short zoom reach but is dim and prone to softness at the long end. Macro focusing is nonexistent.
• The GR Digital IV features a sharp, fast 28mm f/1.9 prime lens, which suits wide-angle shots, environmental portraits, street photography, and landscapes beautifully. Its bright aperture allows substantial background separation and bokeh opportunities - a rarity for compacts.

The GR’s lens is one of its standout assets. Its combination of wide-angle reach and fast optics provides greater artistic potential. The EX-FS10’s zoom lens, while flexible, cannot deliver the same creative depth or low-light usability.
