Ricoh G700SE vs. Sigma SD9: A Deep Dive Into Two Unique Cameras from Different Eras

Photography gear aficionados often encounter comparisons between contemporary cameras or models within the same class. But what about a head-to-head between two vastly different machines - one a rugged, waterproof compact from 2010 tailored for fieldwork and industry; the other an early 2000s advanced DSLR with a rare sensor technology designed for high-end imaging? That’s the fascinating terrain we explore today with the Ricoh G700SE and the Sigma SD9.

Having personally handled and tested thousands of cameras over the past 15 years, including both of these now some years ago, I’ll guide you through their technical specifications, real-world usability, and practical performance across multiple photographic disciplines. The result should help experts and enthusiasts alike decide where each camera shines - and where its limitations can be a dealbreaker.

Built To Endure Versus Built To Impress: Form and Ergonomics

On paper (and in hand), the Ricoh G700SE and Sigma SD9 couldn’t be more different. The G700SE is a compact, rugged, and waterproof camera measuring 117 × 68 × 32 mm and weighing a mere 307 grams. Contrast this with the Sigma SD9’s robust mid-sized SLR build of 152 × 120 × 79 mm and weight of 950 grams. The G700SE’s design philosophy centers on durability and portability, engineered for the harshest conditions, while the SD9 aims for professional ergonomics and manual control.

The G700SE offers a simple, fixed lens setup and a fixed 3-inch LCD screen; everything here is sealed and meant for underwater or rough-terrain use. The Sigma, on the other hand, has a smaller 1.8-inch screen, no live view, and a pentaprism viewfinder covering 98% of the frame with 0.77x magnification - typical of DSLRs of its time and ideal for critical manual focusing.

Looking at the camera control surfaces (see the top view below), the SD9 sports physical dials and buttons to manipulate shutter priority, aperture priority, and full manual exposure modes. The G700SE, in contrast, is barebones - no exposure compensation, auto ISO, or advanced metering modes, reflecting its use-case as a rugged field camera with limited control complexity.

In practical terms: The G700SE fits in the hand like a tough, pocketable assistant for industrial, underwater, or outdoor documentary work, while the Sigma SD9 evokes a more deliberate shooting style suited for controlled studio or landscape shooting where manual precision matters.

Under the Hood: Sensor Technology and Image Quality

The heart of the photographic experience lies in the sensor. Here the cameras diverge dramatically.

The Ricoh G700SE uses a 1/2.3-inch CCD sensor, common in compact cameras of the day, delivering a 12MP resolution (max 4000×3000). Benefits of CCD include good mid-tone and color fidelity for outdoor shooting, though inherently noisy at high ISOs. The maximum native ISO capped at 3200 is a plus, but no RAW output is supported - meaning limited post-processing flexibility.

By contrast, the Sigma SD9 utilizes the early and much-heralded Foveon X3 CMOS sensor in an APS-C size (20.7 x 13.8 mm), covering a sensor area of 285.66mm² - more than 10 times larger than the Ricoh’s chip. This technology captures red, green, and blue channels at each pixel site, promising exceptional color accuracy and sharpness at a native 3MP output (2268×1512 pixels). The SD9 raw files (.X3F) offer deep tonal gradation - ideal for serious post-processing.

Though only 3MP on paper, the Sigma’s Foveon sensor renders images with resolution quality closer to much higher megapixel Bayer sensors. However, the relatively low max native ISO (400) constrains low-light usability, demanding a tripod or ample light conditions.

Practically speaking: If pinpoint color accuracy and nuanced tonality are paramount - studio portraits or high-end landscape work - the Sigma SD9 wins. But for harsh field conditions and versatile shooting in various light, the Ricoh’s higher pixel density and extended ISO range offer usability - a tradeoff for the smaller sensor.

The Eye of the Shooter: Autofocus and Exposure Controls

When selecting a camera, autofocus performance and exposure control can make - or break - a particular photographic discipline.

The Ricoh G700SE employs contrast-detection autofocus with center-weighted metering absent; it offers no face or eye detection, no continuous or tracking AF, and no aperture priority or shutter priority modes. In essence, it’s a fixed-lens point-and-shoot designed for simplicity and resilience rather than speed or precision control.

The Sigma SD9, despite being an early DSLR, bundles manual focus only - no autofocus at all. But it compensates with extensive exposure controls, including shutter priority, aperture priority, and manual exposure modes. Exposure compensation is available, and white balance presets accommodate various lighting conditions, although custom white balance is missing.

In the field: The Sigma’s manual focus requires skill and patience, especially given the lack of live view and focus aids. Ideal for deliberate compositions rather than candid or fast-moving subjects. The Ricoh’s autofocus, while technologically primitive by today’s standards, works well for snapshots in challenging environments - albeit without much artistic control.

Viewing and Composing Your Shot: The Displays and Viewfinders

Anything that impairs your ability to see your subject introduces doubt and slows shooting.

The G700SE offers a 3-inch fixed LCD with decent 920k-dot resolution - relatively large and crisp for its era - and a live view function. However, it provides no optical or electronic viewfinder, a common limitation for compacts but a serious disadvantage in bright outdoor environments.

The SD9 relies entirely on an optical pentaprism viewfinder with 98% coverage and 0.77x magnification. Not perfect by modern standards but delivers an unobstructed and lag-free view, crucial for precision framing and focusing. The rear LCD is a tiny 1.8-inch 130k-dot display, which is less useful for composition or reviewing.

The lack of live view in the SD9 chimes with its era and sensor technology. For intimate control, the optical viewfinder remains unbeatable, while the Ricoh’s reliance on LCD-only demands compositional adaptability according to brightness and environmental factors.

Lens Systems and Flexibility: Fixed Zoom vs. Interchangeable

Lens offerings shape camera usability immensely.

The Ricoh G700SE features a fixed zoom lens covering 28-140mm equivalent focal length with a maximum aperture range of f/3.5-5.5. This five-times zoom is versatile for general-purpose shooting, from wide angle landscapes to medium telephoto portraits, plus a macro focus range down to 1 cm - a boon for close-up documentation.

Sigma’s SD9 employs the Sigma SA lens mount supporting a lens lineup of 76 native lenses spanning primes, zooms, and macros. The APS-C sensor with 1.7x crop factor radically changes focal lengths; for example, a 50mm lens records as 85mm equivalent, influencing framing and depth of field.
