Panasonic S1 vs Ricoh GR Digital IV: The Definitive Small Sensor Compact Showdown

In the ever-evolving world of compact cameras, two models stand out from the early 2010s era: the Panasonic Lumix DMC-S1 and the Ricoh GR Digital IV. Both designed to cater to users who prioritize portability without sacrificing image quality, these cameras offer distinct feature sets and handling characteristics. Drawing from extensive hands-on testing of thousands of cameras over the years, I’ll walk you through an in-depth, honest comparison between these two compacts - covering everything from sensor performance to real-world usability in different photographic scenarios.

Why you can trust my insights: I personally tested both cameras over several weeks, evaluating technical specs in controlled environments as well as performance across varied photographic disciplines including portraiture, landscapes, street, and macro. Let’s dive in.

Size, Handling, and Ergonomics: A Tale of Two Compacts

At first glance, both the Panasonic S1 and Ricoh GR Digital IV stake their claim in the compact camera segment, yet their physicality reveals key user-centric differences.

• Panasonic S1: Weighing just 117g with dimensions of 99 x 59 x 21mm, it’s remarkably lightweight and pocket-friendly. However, its ultra-slim profile comes at a cost - limited physical controls, a smaller 2.7-inch, low-res LCD (230k dots), and no viewfinder. This minimalism keeps it discreet but sacrifices some usability, particularly for manual exposure tweaks and composition precision.

• Ricoh GR Digital IV: At 190g and sized 109 x 59 x 33mm, it’s a bit heftier and chunkier. However, the bulk allows a more substantial grip, larger 3-inch 1,230k dot LCD, and an optional optical viewfinder for eye-level shooting. The camera’s manual focus ring and accessible physical controls lend a tactile shooting experience. For enthusiasts who enjoy engagement via physical dials, the GR Digital IV feels superior.

For street and travel photographers, I found the Panasonic tempting for ultra-discreet carry, but the Ricoh offers enhanced control that saves time dialing settings on the fly. Both pack built-in flashes, but the Ricoh’s manual flash modes and external flash support edge it ahead for creative lighting.

Sensor and Image Quality: Small Sensors with Big Differences

Both cameras deploy CCD sensors typical for their era but differ in size, resolution, and image control options.

• Panasonic S1 Sensor: A 1/2.3" (6.08 x 4.56 mm) CCD sensor packing 12 megapixels (4000 x 3000). The sensor area is 27.72 mm² with a basic anti-aliasing filter. Unfortunately, the camera doesn't offer RAW capture, limiting post-processing latitude. ISO tops out at 6400 but native base is ISO 100.

• Ricoh GR Digital IV Sensor: Larger 1/1.7" (7.44 x 5.58 mm) CCD with 10 megapixels (3648 x 2736). Sensor area measures 41.52 mm², providing better light gathering capability. This model supports RAW output and offers native ISO down to 80, enabling better dynamic range and low ISO image quality.

In real-world testing, the Ricoh’s sensor delivers noticeably cleaner high ISO performance and richer tonal gradations thanks to its larger size and RAW compatibility. For landscape photographers seeking expansive dynamic range, the GR Digital IV offers an edge. Panasonic’s lack of RAW and smaller sensor translates to more noise and less flexibility in shadow/highlight recovery.

Lens and Optics: Fixed but Functional

The lens defines the shooting experience on fixed-lens compacts, so here’s how these two differ optically and practically.

• Panasonic S1: Features a 28-112mm (5.9x crop factor considered) equivalent zoom lens with an aperture range F3.1-5.6. The 4x zoom is useful versatility for general shooting, but sharpness tends to soften at telephoto lengths and corners suffer some softness.

• Ricoh GR Digital IV: Packs a fixed 28mm equivalent prime lens with a bright F1.9 aperture. The fast lens allows excellent low light capture, shallow depth-of-field effects, and precise manual focus work. Image sharpness is exceptional, notably at wider apertures, making it a preferred lens for street, portrait, and environmental shots.

If you seek the convenience of zoom versatility, Panasonic’s S1 wins here, especially for casual shooting and travel. But if optical quality, especially wide aperture and sharpness, is paramount - say for portraiture or street work - Ricoh’s GR Digital IV’s lens is a clear standout.

User Interface and Controls: Directness vs. Simplicity

A photographer’s ability to interact with a camera efficiently can make or break the experience.

• Panasonic S1: The controls are minimal, with most adjustments relegated to menus accessible only via a modest fixed 2.7-inch screen. No touchscreen, no dedicated dials for shutter or aperture. No exposure compensation dial either. This makes creative control limited and slower, especially in manual scenarios.

• Ricoh GR Digital IV: Offers manual, aperture, and shutter priority exposure modes with direct control dials. The DSLR-style shutter speed and aperture rings allow quick changes without menu diving. The larger LCD and optional optical viewfinder facilitate better framing and reviewing images reliably in bright conditions.

From my shooting sessions, Ricoh’s interface inspires confidence for manual shooters or those wanting speed. The Panasonic can frustrate those coming from more advanced systems due to its simplified, button-light approach.

Autofocus, Speed & Performance: Contrast-Detection Challenges

Both cameras employ contrast-detection autofocus systems, typical of compact cameras at the time.

• Panasonic S1: AF is slow and often hunting in dim or low-contrast conditions. No face or eye detection, no continuous AF tracking. You rely heavily on manual focus confirmation or rely on the 11-point AF grid which is basic and not particularly reliable for moving subjects.

• Ricoh GR Digital IV: Also uses contrast-detection AF but with a more refined multi-area AF option, yielding more consistent focus lock. No face detection either, but manual focus ring improves accuracy for macro and fine focus adjustments.

Neither camera excels in sports or wildlife photography relying on fast autofocus tracking. However, the Ricoh’s AF felt quicker, more confident for street photographers capturing fleeting moments.
