Ricoh GXR GR Lens A12 28mm F2.5 vs Samsung SL720: A Deep Dive Primer for Discerning Photographers

Choosing the right camera is a complex decision that hinges on more than just megapixel counts or price tags. It demands a nuanced look - sensor tech, lens quality, handling, autofocus systems, and how each tool fits into your photographic vision. Today, I’m putting two very differently focused, yet occasionally overlapping cameras under the microscope: the Ricoh GXR GR Lens A12 28mm F2.5, released in 2010, and the Samsung SL720 from 2009. They represent distinct classes - the GXR as a compact mirrorless rangefinder-style camera with a fixed but exceptional 28mm lens, and the SL720 as an ultracompact point-and-shoot with a versatile zoom.

Over hundreds of hours testing and shooting with these cameras, I’m bringing you an authoritative, hands-on comparison. From landscape vistas to street corners, control feel to sensor tech, and price-value considerations, this is the rigourous breakdown you need to make an informed decision.

First Impressions: Handling and Physical Presence Matter

Before pixel-peeping, you physically interact with a camera. Size, weight, button ergonomics - these shape whether you want it in your hands all day or stuffed in a bag and forgotten.

The Ricoh GXR GR Lens A12 is distinctly rangefinder-style: compact but substantial with a solid, boxy build measuring 113x70x56 mm and weighing only 140 grams (body-only; lens module adds a little). Its metal construction feels instantly premium - firmer grip than the SL720’s plasticky shell. The GXR's modest footprint punches above its weight when considering the APS-C sensor tucked inside, a much larger imaging area than most compacts.

The Samsung SL720, by contrast, is built for pocket convenience. At 92x61x23 mm and 168 grams, it fits nicely into a jacket pocket and slips into any small bag. But that thin profile comes with compromises: the grip feels minimal, and while the controls are intuitive for a casual shooter, there’s no tactile refinement you’d expect from a system camera.

Ergonomically, if you crave physical dials and the tactile feedback of purposeful button placement, the Ricoh is the clear winner. It sports dedicated shutter speed and aperture controls - features I personally applaud for fast, instinctive shooting. The SL720 uses menus and on-screen commands for settings changes, which can slow you down in dynamic lighting or moments demanding quick reflexes.

A Top-Down Look at Controls: Where Design Meets Usability

Let's take a closer look at the control architecture, which profoundly affects your shooting workflow.

The Ricoh GXR embraces classic shooter ergonomics: a top plate adorned with a shutter speed dial, exposure compensation dial, and a well-placed shutter button. The absence of a built-in viewfinder nudges you towards LCD composition or the optional external electronic viewfinder. While some may grumble about the viewfinder omission, I found the large 3-inch screen (with 920k-dot resolution) perfectly adequate, especially paired with the GXR’s strong manual focus capabilities.

The SL720’s control layout is minimalist. It includes zoom toggle, shutter release, and mode dial but lacks manual exposure controls - no shutter priority, aperture priority, or manual mode. This limits creative control but streamlines casual point-and-shoot operation.

While touchscreen is increasingly de rigueur in 2009–2010 compacts, neither camera offers it, so you rely heavily on button navigation - faster on Ricoh’s physical dials, more menu-dependent on Samsung.

Sensor Technology and Image Quality: The Heart of the Matter

This is where the cameras diverge sharply. The Ricoh GXR incorporates an APS-C sized CMOS sensor measuring 23.6 x 15.7 mm with 12 megapixels, while the Samsung SL720 uses a much smaller 1/2.3-inch CCD sensor at about 6.08 x 4.56 mm, also outputting roughly 12 megapixels.

The Ricoh’s sensor area is about 370 mm² versus a minuscule 27.7 mm² in the Samsung. That’s a roughly 13-fold difference in surface area, a metric that directly impacts dynamic range, noise performance, and depth of field control.

To put it practically: in daylight, the Ricoh yields crisper images with richer colors and smoother tonal gradations. Low-light reveals its CMOS design advantage as it sustains cleaner files up to ISO 3200 versus the Samsung’s ISO 1600 max. The CCD sensor in the SL720, while respectable for casual photos, introduces more noise as ISO rises and suffers from narrower dynamic range, limiting punchy highlights and shadow detail capture.

This sensor disparity alone positions the Ricoh for more demanding photographers needing superior image quality, while the SL720 targets casual snapshotters prioritizing zoom versatility and pocket size.

Commendable Lenses but With Distinct Objectives

Lens optics define your photographic potential. The Ricoh GXR is famously modular - the lens and sensor come as a single unit (the A12 unit here with a sharp 28mm F2.5 lens). This fixed focal length (equivalent to about 40mm on full frame due to 1.5x crop factor) delivers excellent sharpness, low distortion, and welcoming bokeh for portraits. It’s an optically optimized package designed to maximize image quality rather than zoom grunt.

Conversely, the Samsung SL720 sports a 28-102mm (35mm equivalent) zoom with a variable aperture of F2.8-5.7. It offers 3.6x optical zoom, beneficial for casual shooting and travel. However, this lens, while versatile, exhibits softness at telephoto and noticeable chromatic aberrations in corners. Aperture-wise, it lacks the low-light punch of the Ricoh’s constant F2.5.

For portrait photographers who value bokeh and crisp detail, the Ricoh’s 28mm prime lens is a better creative tool. The SL720’s zoom flexibility suits general snapshots and travel where framing versatility outweighs absolute optical performance.

Autofocus Systems: Speed, Accuracy, and Practical Impact

When evaluating autofocus, I conducted real-world tests tracking moving subjects outdoors and focusing on static objects under varying lighting.

The Ricoh GXR utilizes contrast-detection autofocus with 9 area options and face detection; it supports continuous AF but lacks phase-detection points or eye/animal focus capabilities popular in modern cameras. While respectable, AF speed is moderate - no lightning-fast lock but reliable accuracy within well-lit scenes. Manual focus is fully supported, which is a boon for studio or street photographers demanding precision.

The Samsung SL720 uses a simpler contrast-detection AF with no continuous AF and only center-weighted area focus available. Focus speed is slower overall and hunting was noticeable in dim conditions.

For sports, wildlife, or fast-paced street photography, neither camera shines - though the Ricoh’s modest continuous AF and additional focus area options offer a slight edge. For portraits requiring precise eye detection, modern hybrids surpass them, but Ricoh leads here due to face detect and manual focus option.

Shooting Performance, Shutter Speeds, and Burst Modes Explored

The Ricoh GXR offers a top shutter speed of 1/3200s, double that of the Samsung SL720’s 1/1500s max. This extended shutter ceiling enables the Ricoh to shoot wide-open in brighter light while managing exposure without ND filters.

Continuous shooting tops out at 5 fps on the Ricoh, while Samsung does not advertise a burst mode. This distinction makes the GXR more suitable for capturing fleeting moments like street scenes or spontaneous action.

Exposure modes on Ricoh include shutter priority, aperture priority, and manual exposure - a rarity for compact cameras of this era. Samsung only provides fully automatic or scene modes, limiting creative exposure adjustments.

Viewing and Interface: How You Compose and Review Matters

Both cameras come with fixed, non-touch TFT LCD screens, but the Ricoh’s 3” 920k-dot screen vastly outshines the SL720’s smaller 2.7" 230k-dot display. This makes framing and image review more comfortable and precise on the Ricoh. The SL720’s screen is standard for compacts but subpar by today’s standards, occasionally making autofocus confirmation and histogram reading more challenging.

Neither camera has an integrated electronic viewfinder (EVF), but Ricoh offered an optional external EVF for the GXR system, improving composition in bright sunlight.

Interface-wise, Ricoh offers customizable buttons and intuitive dialing, suiting advanced users accustomed to tactile feedback. Samsung’s menu system is basic, designed for instant point-and-shoot use but frustrating if trying to dive deeper into controls.

Real-World Image Quality Showdown: Sample Images and Color Rendition

Look at the samples below from both cameras, each representing typical shooting scenarios - daylight landscape, indoor portrait, close-up detail, and low light.

The Ricoh’s APS-C sensor combined with the sharp fixed 28mm lens produces punchy colors, excellent detail, and impressive low noise in shadows. Skin tones are natural and smooth - a boon for portraits and street photography alike.

Samsung's images, while reasonably sharp at base ISO outdoors, struggle indoors and in low light, exhibiting noise, lower sharpness, and less vibrant color rendition. The zoom lens introduces slight softness at long focal lengths.

Specialized Photography Genres: Where Each Camera Excels (And Where They Struggle)

Portrait Photography:
Ricoh’s larger sensor, natural skin tones, and large aperture lens make it the clear choice. Eye detection lacks, but face detection and manual focus help achieve sharp, aesthetic portraits with pleasing background bokeh. Samsung’s smaller sensor and slower lens limit portrait quality to snapshots.

Landscape Photography:
The GXR’s superior dynamic range and resolution yield detailed, vibrant landscapes. Weather sealing is absent on both, but Ricoh’s sensor size dominates here. Samsung is less ideal due to narrow dynamic range and sensor limitations.

Wildlife Photography:
Both struggle with autofocus speed and lack telephoto power. Samsung’s 3.6x zoom offers range advantage but sacrifices image quality. Ricoh’s prime lens restricts framing, but faster shutter speeds and burst mode help.

Sports Photography:
Ricoh’s burst rate of 5 fps and shutter options enable better capturing of fast action. Samsung lacks continuous shooting. Neither excels due to autofocus limitations.

Street Photography:
Ricoh is excellent due to its quiet shutter, manual controls, and compact rangefinder style. Samsung’s stealth factor is higher physically, but slower AF and zoom use compromise spontaneity.

Macro Photography:
Samsung offers closer 5 cm focusing, useful for casual macro. Ricoh lacks macro focus range but with extension tubes (third-party) can be adapted. Neither has image stabilization.

Night and Astro Photography:
Ricoh’s better ISO range and exposure modes, including manual exposure, give it a notable edge. Samsung’s restricted ISO and sensor limitations hamper low-light capture.

Video Capabilities:
Ricoh records HD video at 1280 x 720p at 24fps in MPEG-4 format, whereas Samsung is limited to 640 x 480 max resolution, with Motion JPEG compression - outdated and low quality. Neither offers microphone or headphone ports.

Travel Photography:
Samsung’s pocketability is outstanding for travel convenience. Ricoh trades off compactness for image quality, better suited for deliberate travel photography rather than grab-and-go snapshots.

Professional Work:
Ricoh’s RAW support, APS-C sensor, and manual controls position it as a more capable tool for professionals needing reliable files and workflow integration. Samsung’s JPEG-only output and simple controls restrict professional viability.

Build Quality, Weather Sealing, and Durability Considerations

Neither camera provides formal weather sealing, dustproofing, or shock resistance. The Ricoh’s metal body imparts a perception of ruggedness and longevity, while the SL720’s plastic chassis feels more delicate. I wouldn’t trust either in extreme conditions, but the Ricoh will likely endure years of deliberate use with fewer cosmetic scars.

Storage, Battery Life, and Connectivity

Storage-wise, both accept SD or SDHC cards for ample storage flexibility.

The Ricoh’s claimed battery life is 320 shots per charge - not stellar but reasonable given its sensor and processor. The SL720’s battery life data is unadvertised but generally low in compacts of this generation - especially considering video and zoom use. Both use proprietary battery packs (DB-90 for Ricoh, SLB-10A for Samsung).

Connectivity is primitive in both cameras: no Wi-Fi, Bluetooth, or NFC. Ricoh offers USB 2.0 and HDMI out; Samsung offers only USB 2.0. For instant image transfer or remote control, modern cameras far outpace these models.

Price and Value: What You Get For Your Money

The Ricoh GXR GR Lens A12 28mm F2.5 commands around $566 new (historical), while the Samsung SL720 was available at about $119.

This price gap reflects the fundamentally different ambitions:

• Ricoh targets enthusiasts wanting image quality and manual control in a compact system.
• Samsung aims at casual users needing zoom flexibility and simple operation at a budget.

While the Ricoh’s price may seem steep, you’re paying for APS-C sensor performance plus lens quality and manual exposure control. The SL720 represents good value as a versatile ultracompact for everyday snapshots but won't satisfy users seeking creative flexibility or professional-grade results.
