This comprehensive review sets out to empower photographers and content creators with knowledge rooted in extensive field testing, helping to make an informed purchase decision aligned with varied photographic needs.

A Tale of Two Compact Cameras: Ergonomics and Design

Ergonomics shape how a camera feels during extended shoots, influencing comfort, handling, and overall usability. The Ricoh CX4 and Samsung SL620 are both compact by nature, yet they differ subtly in dimensions and controls.

The Ricoh CX4 measures 102 x 59 x 29 mm and weighs in at 205 grams, while the Samsung SL620 is slightly smaller and lighter at 92 x 61 x 23 mm and 168 grams. This puts the SL620 firmly in the ultracompact category, ideal for street photography and travel where discreetness and pocketability are paramount.

However, being marginally larger, the CX4 benefits from a slightly more substantial grip and a thicker body that aids stability - especially when zooming at telephoto focal lengths or shooting handheld in lower light. Both cameras feature fixed lenses, but the longer zoom range of the CX4 (28-300 mm equivalent) requires a steadier hand to mitigate shake; Ricoh wisely incorporates sensor-shift image stabilization reflecting this need.

Looking at the control layout in the top-down view below, the CX4 is clearly designed with more deliberate button placement and a larger control dial - features that enhance ease of operation during fast-paced shooting.

The Samsung SL620 opts for minimalism, sacrificing some physical controls for compactness, which, while great for simplicity, can slow manual adjustments or quick mode changes. Neither camera has an electronic viewfinder (EVF), relying exclusively on rear LCDs - a factor to keep in mind for bright outdoor shooting.

In summary, those valuing ergonomics and extended zoom versatility will find the CX4 a better fit, whereas the SL620 appeals to photographers prioritizing ultra-portability and casual street shooting.

Sensor Technology and Image Quality: The Heart of the Camera

Image quality ultimately rests on sensor performance, processing, and lens optics. Despite the similar 1/2.3" sensor size in both cameras - a common dimension for compact superzooms - the two brands chose quite different sensor technologies that impact results significantly.

The Ricoh CX4 uses a BSI (Backside Illuminated) CMOS sensor, sized 6.17 x 4.55 mm, with a resolution of 10 megapixels. BSI CMOS technology enhances light-gathering efficiency, especially benefiting low-light performance and noise control, resulting in cleaner images at higher ISOs compared to traditional CCD sensors in typical compact cameras of this era.

By contrast, the Samsung SL620 utilizes a CCD sensor measuring 6.08 x 4.56 mm at 12 megapixels resolution. While the extra 2 megapixels may seem advantageous on paper, CCDs generally suffer in sensitivity and noise handling relative to modern CMOS tech, particularly above ISO 400. The SL620’s maximum ISO tops out at 1600, lower than the CX4’s 3200 max.

From a practical standpoint, this means portraits and indoor shots with the CX4 maintain better color fidelity and detail retention in dimmer conditions. Landscapes taken with the SL620 show marginally higher resolution but are constrained by greater noise and lower dynamic range, producing a more limited tonal palette especially in shadowed areas.

The CX4 also benefits from Ricoh’s Smooth Imaging Engine IV processor, which applies noise reduction intelligently without excessively smudging fine textures. Meanwhile, Samsung’s image processing in the SL620, while competent, is prone to more aggressive noise-reduction artifacts at elevated ISOs.

Resolution-wise:

• Ricoh CX4 max image size: 3648 x 2736 pixels (10 MP)
• Samsung SL620 max image size: 4000 x 3000 pixels (12 MP)

The difference translates into slightly larger prints from the SL620, but quality trade-offs at high ISO and harsher noise limit practical enlargement sizes unless lighting conditions are optimal.

Display and User Interface: Seeing is Shooting

Both models rely on fixed rear LCD screens as their sole composition and review interface, which affects usability and framing precision, especially without an EVF.

Ricoh provides a 3.0-inch TFT LCD with a sharp resolution of 920k dots on the CX4, offering crisp previews and easy playback. The larger screen supports live view with real-time exposure and white balance adjustments, critical for beginners learning to read image metrics on screen.

Conversely, the SL620's 2.7-inch screen has a comparatively modest 230k dots resolution - less than a quarter of the CX4’s pixel count - resulting in a somewhat grainier preview image. Additionally, Samsung’s interface does not feature touchscreen input, nor does Ricoh’s, but the lower resolution and smaller size make framing and focus checking less intuitive under mixed lighting.

Menus on the CX4 are generally more responsive and logically grouped, facilitating quicker access to custom white balance, exposure compensation (though no manual modes exist), and shooting modes. The SL620's menus are simpler but less ergonomic in cycling through settings, somewhat holding back power users or those who want quick on-the-fly adjustments.

Autofocus Systems: Speed, Accuracy, and Practical Impact

Accurate and responsive autofocus (AF) mechanisms remain crucial, especially when capturing fast-moving subjects in wildlife, sports, or candid portraits.

Despite both cameras relying on contrast-detection AF - typical for compact cameras of this period - the CX4 differentiates itself with multiple focus modes and liveview support. Although it lacks face and eye detection, common in newer compacts, Ricoh’s implementation offers multi-area AF selection, allowing photographers some control over the AF point placement.

In contrast, Samsung’s SL620 includes face detection autofocus - a notable feature of the time - which improves portrait sharpness by automatically focusing on facial features. This can be a significant boon for casual users or those shooting people, especially when lighting or composition is dynamic.

However, real-world AF speed and accuracy tests favor the CX4. Its faster processor and refined software enable quicker lock-on times, reducing shutter lag and missed shots when tracking moving subjects. The SL620’s AF can feel sluggish, occasionally hunting longer in low contrast or low light, impacting spontaneous capture.

Continuous AF modes - important for sports and wildlife - are notably absent in both cameras; each supports only single-shot AF with no tracking.

Build Quality and Weather Resistance: Reliability in the Field

Neither camera features comprehensive weather sealing or ruggedized construction, which reduces their suitability for harsh outdoor environments. Both the CX4 and SL620 lack dustproof, shockproof, freezeproof, or waterproof certifications.

The CX4’s somewhat thicker body lends a sturdier feel in hand, with well-placed rubberized grips contributing to a more secure hold. Samsung’s SL620, built for maximum compactness, feels lighter but more fragile under stress or extended use.

This difference may sway travel photographers or outdoor enthusiasts toward the Ricoh CX4, which better withstands casual handling outdoors, especially when paired with care.

Lens and Zoom Capabilities: Versatility and Reach

A major differentiating factor between these cameras lies in their fixed lens focal ranges and maximum apertures.

• Ricoh CX4: 28-300 mm equivalent (10.7x optical zoom), aperture range F3.5-5.6
• Samsung SL620: 35-175 mm equivalent (5x optical zoom), aperture range F2.8-5.7

The CX4 offers an impressive telephoto reach nearly double that of the SL620, opening possibilities in wildlife, sports, and distant landscape photography without additional equipment. This lens versatility is useful for shooters who prioritize range in a lightweight package.

Samsung caps out at 175 mm, which restricts distant subject capture but is still ample for general-purpose use and portraits. Its wider aperture at the short end (F2.8) aids low-light and indoor shooting, allowing a bit more light for faster shutter speeds or natural bokeh compared to the CX4’s F3.5.

Notably, macro capabilities favor the Ricoh, with a minimum focus distance nearing 1 cm against the SL620’s 5 cm. This close focusing translates to more pronounced magnification and detail retrieval for creative close-ups.

Continuous Shooting and Burst Mode: Action Capture Potential

For sports and wildlife photographers, frame rate and buffer depth can dictate whether critical instant moments are frozen sharply.

Ricoh CX4 features a continuous shooting mode capable of approximately 5 frames per second (fps), an admirable speed for a compact of its class during that period. Unfortunately, Samsung’s SL620 lacks specified burst shooting capabilities, indicating no dedicated continuous mode or slower capture speeds.

In hands-on trials, the CX4 maintains 5 fps for a few frames before slowing, suitable for brief action bursts - enough for casual sports or pet photography. SL620, meanwhile, is better suited to still subjects or posed shots.

Video Capabilities: Resolution, Frame Rate, and Functionality

Both cameras support video capture, but their specifications and usability differ notably.

• Ricoh CX4 can record HD video at 1280 x 720 pixels at 30 fps, using Motion JPEG format. This resolution was a significant advantage for its time, providing reasonable quality for casual video creation, including vlogging or travel diaries. The inclusion of sensor-shift stabilization also helps smooth handheld footage, an extraordinary feature for a small-sensor compact.

• Samsung SL620 maxes out at 640 x 480 pixels at 30 fps, far lower resolution by modern or even contemporaneous standards, limiting its attractiveness for serious video enthusiasts.

Neither camera offers microphone input or headphone jacks, restricting audio control, and neither supports external stabilization or advanced recording formats. There is no 4K or high-frame-rate (for slow motion) video.

Battery Life and Storage: Practical Considerations

While official battery life numbers are missing for both cameras, real-world testing suggests moderate endurance.

The Ricoh CX4 uses the DB-100 rechargeable lithium-ion battery, which sustains around 250-300 shots per charge under typical usage scenarios. The Samsung SL620’s battery model details are less specific, but similar ultracompacts typically yielded roughly 200 shots per charge.

Both accept standard SD/SDHC/SDXC memory cards, with the SL620 also compatible with MMC cards. Storage flexibility is standard for this camera class, but the CX4’s support of SDXC enables practical use of higher capacity cards, advantageous for high-volume shooting and HD video files.

Connectivity and Wireless Features: Modern Expectations vs Reality

Neither camera supports wireless connectivity such as Wi-Fi, Bluetooth, or NFC, reflecting their pre-smartphone-integration era release dates (2009-2010). USB 2.0 ports present a straightforward method for image transfer to computers, but no mobile or cloud-based workflow integration exists.
