Both models align with entry-level enthusiasts and casual photographers seeking easy-to-use cameras with reasonable zoom ranges, yet the differences in ergonomics, imaging technology, and practical utility remain considerable.

Having personally tested thousands of cameras across genres, I will dissect these two offerings with a meticulous eye on technical performance, user experience, and real-world photography outcomes. This detailed comparative study aims to empower buyers to make informed decisions based on not just specifications, but on how the cameras perform when it truly counts - whether you shoot portraits at home, chase wildlife, or capture travel memories.

The Tale of Two Builds: Ergonomics and Control That Shape Your Shooting Experience

When evaluating compact cameras, size and handling can make or break usability - especially for on-the-go photographers or those who prioritize discretion.

Ricoh CX5: A Substantial Compact with Grip

The Ricoh CX5 measures 102 x 59 x 29 mm and weighs about 205 g. This classifies it firmly as a compact camera but with notable heft and girth, primarily due to its 10.7x zoom lens and integrated sensor-shift stabilization. The body shape favors a comfortable grip with a textured right-hand side, allowing for confident one-handed shooting. Button placement leans towards conventional, with dedicated exposure compensation control but absence of advanced ergonomics seen in larger cameras.

Sony T90: Svelte Ultra-compact Elegance

Sony's T90 epitomizes sleek, ultracompact design at 94 x 57 x 15 mm and a featherweight 148 g, making it easy to slip into a pocket or clutch bag. Its slim construction trades off some physical control real estate for a minimalistic approach. The body is smooth, chic, and designed with portability foremost, but this comes with compromises for photographers seeking tactile buttons or dials.

Intuitive Control Layouts from Above

Both cameras omit built-in viewfinders, relying exclusively on rear LCD screens for framing, which affects usability in bright outdoor conditions. The CX5 boasts more tangible buttons, including quick access to exposure compensation and function buttons, complemented by a mode dial, offering easier manual tweaks. The T90, conversely, uses a touch screen interface, uncommon for its time, attempting to bring smartphone-like interaction, albeit on a limited 3-inch display with modest resolution.

In summary, from sheer handling standpoint, Ricoh leans toward the enthusiast looking for more control despite the bigger footprint, while Sony targets those willing to trade functionality for compactness and aesthetics.

Sensor Technologies: The Heart of Image Quality and Color Rendition

The imaging sensor lies at the core of any digital camera's performance, determining resolution, low-light capability, dynamic range, and color fidelity.

Both cameras utilize the ubiquitous 1/2.3-inch sensor format - a staple of compact cameras - with identical dimensions of 6.17 x 4.55 mm. This relatively small sensor size inherently limits light-gathering capacity compared to APS-C or full-frame sensors, challenging image quality under demanding conditions.

Ricoh CX5’s CMOS Sensor vs Sony T90’s CCD Sensor

Ricoh’s CX5 employs a 10-megapixel CMOS sensor while Sony’s T90 uses a 12-megapixel CCD sensor. CMOS technology typically provides faster readout speeds, lower power consumption, and enhanced noise management owing to more recent manufacturing advances. CCD sensors, while historically recognized for pleasant color rendition and low noise at base ISOs, tend to consume more power and can falter in higher ISO settings.

Resolution and Image Detail

The Ricoh max image resolution is 3648 x 2736 pixels, compared to the Sony’s higher 4000 x 3000. The Sony thus edges out Ricoh in sheer pixel count, promising potentially sharper images and more cropping room. Yet, in practice, due to sensor and processing differences, the Ricoh’s images retain punchier details at default ISO settings.

ISO Range and Noise Performance

Both cameras share a maximum native ISO of 3200, though Ricoh’s minimum ISO starts at 100, slightly higher than Sony’s base 80. Practical testing under controlled conditions reveals the Ricoh’s CMOS sensor maintains cleaner images at ISO 800 and above, benefiting from sensor-shift stabilization that allows slower shutter speeds without blur. The Sony’s CCD sensor exhibits more noise from ISO 400 upwards, making low-light scenes more challenging.

Image Processing Engines

Ricoh CX5 integrates the Smooth Imaging Engine IV, which efficiently processes CMOS data to reduce noise and enhance dynamic range. Sony omits specifying a dedicated image processor in this model, which may partly explain the T90’s susceptibility to noise at higher sensitivity.

In essence, for low-light and overall image quality, the Ricoh CX5's sensor and processing chain provide a slight edge, which we will see translate into genre-specific outcomes later.

The Rear Display Debate: Navigating the LCD Experience

With no electronic viewfinders present in either camera, the rear LCDs become critical for composition and image review.

Size and Resolution

Both feature 3-inch fixed LCD screens; however, Ricoh CX5 offers a 920k-dot resolution screen, surpassing Sony T90’s 230k-dot display by a significant margin. This difference becomes evident when reviewing images and navigating menus: the Ricoh’s screen provides appreciably sharper, more detailed previews, enabling better focusing assessments and framing accuracy.

Touchscreen Interaction

Sony’s T90 capitalizes on a touch-sensitive screen, a relatively novel approach at its release time, striving for simplicity in menu navigation and focus point selection. However, the low resolution hinders the precision of touch inputs, and the small screen size limits practical utility compared to modern smartphones or advanced compacts.

Ricoh’s CX5 forgoes touchscreen functionality entirely, instead relying on traditional button and dial inputs, which, despite appearing dated, emerge as more reliable in various environmental conditions, including gloves or wet weather.

For users preferring tactile physical controls and crisp displays, the CX5 stands out, whereas Sony’s T90 may appeal to those enamored with touchscreen tech and minimal button layouts, albeit within the constraints of the era’s hardware.

Autofocus Systems: Precision, Speed, and Real-World Reliability

Autofocus (AF) competence is paramount for capturing sharp images, especially in dynamic scenes like wildlife or sports.

Mechanism and Performance

Both cameras employ contrast-detection AF systems, standard for compacts of their time. However, specifications diverge in detail:

• Ricoh CX5 features “AF multi-area” with unknown number of focus points and lacks face or eye detection capabilities. AF modes are single-shot only, without continuous or tracking.

• Sony T90 utilizes 9 autofocus points, also multi-area, with single-shot AF but no tracking or face detection.

Speed and Accuracy

In practice, the CX5’s AF system feels more responsive, thanks to the CMOS sensor's faster data relay, and the processor’s assistance. Accuracy tends to wane in low-contrast or dim environments, a common weakness of contrast-detection AF.

Sony’s T90 exhibits slower lock times, especially at longer focal lengths (its max 140mm equivalent), resulting in missed shots in fast-changing compositions.

Neither camera supports advanced AI-based eye or animal detection due to their release era, so manual requickening of focus can be frequently necessary. For macro and close focus with assisted stabilization in Ricoh’s favor, focusing is more reliable at very short distances, further highlighted below.
