Ricoh GXR A16 24-85mm vs Samsung ST100: A Deep Dive for Discerning Photographers
When exploring the landscape of cameras circa early 2010s, the Ricoh GXR A16 24-85mm and Samsung ST100 stand as notably different beasts catering to divergent users - the advanced mirrorless enthusiast versus the ultraportable generalist. Having spent many hours and numerous shoots with both models, I’ll guide you through a detailed comparison that blends my hands-on testing experience with technical insights into sensor technologies, autofocus behaviors, and more. This is a no-nonsense, candid assessment of what these cameras mean on the ground for photographers looking to weigh options in their next gear upgrade or sidekick.
Let’s start by setting the stage with the physical designs and how that impacts usability.
Handling and Ergonomics: Rangefinder Elegance Meets Pocketability
The Ricoh GXR A16 24-85mm, announced in early 2012, is built with a rangefinder-style mirrorless body, evoking classic camera handling with a bit of modern twist. It’s hefty at approximately 550 grams and sports dimensions of 114x75x93mm - substantial by mirrorless standards, certainly by compact ones. This robust form factor lends confidence in the hand, especially during extended shoots or when using the rubberized grip and manual focus ring on its fixed zoom lens. The button layout is practical but minimalistic, favoring experienced users who like to tweak settings rather than depend on touchscreen menus.
In stark contrast, the Samsung ST100 is a true ultraportable with a body barely tipping the scales at 155 grams and thin enough to stay unnoticed in most pockets (100x60x20mm). This compactness is complemented by a reasonably large 3.5-inch touchscreen, quick for casual operation but less tactile for precise manual controls. Ergonomically, it’s designed for quick point-and-shoot moments, where fiddling with settings isn’t a priority.
Looking from above, the GXR’s dials and buttons scream “dedicated camera,” while the Samsung appears more like a high-end smartphone masquerading as a camera, underscoring its convenience orientation. Neither features an EVF which may frustrate some, but the Ricoh offers an optional electronic viewfinder add-on if you prefer eye-level shooting stability.
Ergonomics Verdict: For tactile engagement and manual control, the Ricoh wins hands down. If explicit portability and pocket ease are your priority, Samsung’s ST100 is a formidable candidate.
Sensor and Image Quality: APS-C Brilliance vs. Compact Convenience
Image quality fundamentally pivots on sensor size and technology. The Ricoh GXR A16 unit sports a 16MP APS-C CMOS sensor measuring 23.6x15.7mm, a serious imaging engine with ample potential for rich detail, good dynamic range, and reasonable noise control. This sensor area is roughly 13x larger than that in the Samsung ST100.
The ST100 comes with a 14MP 1/2.3-inch (6.17x4.55mm) CCD sensor which, by today’s standards and even in 2010, is definitely on the smaller side. CCDs can produce pleasing color tones but typically fare worse in low light due to limited photosite sizes and lower dynamic range.
During side-by-side image shoots across varied lighting, the Ricoh consistently delivered punchier color fidelity, finer detail in textures like foliage and fabric, and superior low-light performance at ISO 800 and above. The anti-alias filter on the Ricoh’s sensor strikes a balance between sharpness and moiré prevention without overly softening edges.
Meanwhile, the Samsung ST100 excels in bright daylight conditions and benefits from its wider zoom reaching the telephoto range. However, under cloudy conditions or indoor environments, noise and detail loss become evident, particularly beyond ISO 400. The limited dynamic range can cause highlight clipping and shadow crush, meaning landscape photographers should tread cautiously.
Image Quality Takeaway: If pixel-level sharpness, dynamic range, and noise resilience matter - especially for portraits or landscapes - the GXR’s APS-C sensor is the unquestionable champion. The ST100 suffices for casual snaps, daylight travel, and snapshots where immediacy trumps subtle gradations.
Autofocus Systems: Precision or Convenience?
Autofocus behavior can make or break capturing decisive moments. The Ricoh GXR A16 deploys a contrast-detection AF system with face detection and selectable AF areas. It supports single, continuous AF, and live-view focusing. Unfortunately, it lacks phase detection and dedicated face tracking algorithms that have become standard in more contemporary cameras.
Samsung’s ST100 uses contrast detection as well but combines it with touchscreen-based AF selection and face detection, although without continuous AF or tracking. Manual focus is absent on the ST100, though macro focusing reaches as close as 5cm, which is quite commendable for an ultra-compact.
In real-world shooting scenarios, particularly indoors or at dusk, the GXR’s AF delivered more reliable focus acquisition, albeit slower than modern cameras (3.0 fps burst also limits action capture). The ST100’s AF sometimes struggled in low contrast scenes but was snappy enough in bright light.
Autofocus Insight: For deliberate portraiture or landscape focusing, the Ricoh system’s versatility and manual focus override edge out the Samsung’s simpler contrast detection. Sports and wildlife shooters may find both limiting, but the GXR’s continuous AF aid is a slight bonus.
Lens and Focal Range: Fixed Zoom Comparisons
Both cameras feature fixed zoom lenses covering useful focal lengths with different philosophies.
- Ricoh GXR A16: 24-85mm equivalent (1.5x crop factor implied), F3.5-5.5 aperture, rangefinder-style manual ring. This translates roughly to a moderate wide-to-short telephoto zoom, ideal for portraits, street scenes, and travel snapshots.
- Samsung ST100: 35-175mm equivalent, F3.6-4.8, designed primarily for extended reach and convenience, though it lacks manual focus.
While the Ricoh's shorter lens range and slower maximum aperture may challenge indoor or low-light photographers, its manual focusing and more classical optical design offers better control over depth-of-field and bokeh quality. The Samsung’s longer zoom reach is tempting for casual wildlife and travel, but expect soft corners and vignetting wide open.
Given the Ricoh’s APS-C sensor and optical quality, its lens produces images with more pleasing background separation and subject isolation. The ST100’s smaller sensor lightens depth of field inherently, making bokeh less creamy but sometimes more forgiving.
Display and User Interface: LCD Technology and User Experience
Viewing and composing your shot is inherently tied to the quality of your viewing screen.
The Ricoh GXR has a fixed 3-inch TFT color LCD at 920,000 dots, non-touch, yielding sharp, natural color reproduction with decent brightness and viewing angles. Its non-touch interface encourages reliance on physical buttons and dials, which I find enhances control precision once you grow accustomed.
Samsung’s ST100 offers a larger 3.5-inch LCD with 1,152,000 dots and a capacitive touchscreen. This makes navigation much more intuitive for beginners or users accustomed to smartphones, with tap-to-focus and setting adjustments a breeze. The screen shows vibrancy but can be a bit reflective under bright sunlight.
For photographers who value tactile feedback and button shortcuts, the Ricoh’s approach is preferable although it’s less beginner-friendly. For casual shooting or quick frame check, Samsung’s touchscreen is very approachable.
Build Quality and Weather Resistance
Neither camera boasts environmental sealing or rugged protection. Both are designed for indoor/outdoor casual use only.
The Ricoh’s metal-heavy construction imparts a premium feel, with durable mechanical components - the type that inspire confidence for weekend hikes or urban explorations. The Samsung ST100 uses light polycarbonate materials consistent with its ultra-compact ambitions; it’s pocket-friendly but less reassuring in demanding environments.
Neither model is waterproof or shock-resistant, so I advise careful handling when shooting outdoors.
Battery Life and Storage
Here, Ricoh returns a respectable 400 shots per charge with its proprietary DB-90 battery, aligning with mirrorless camera norms of the time. Storage is limited to SD/SDHC cards with one slot and includes internal buffer memory.
Samsung’s ST100 lacks published battery life specs but, generally, point-and-shoot ultracompacts fare better due to slower processors and smaller screens. It supports MicroSD/MicroSDHC cards. Both cameras utilize USB 2.0 for transfers and offer HDMI output for image playback.
Video Capabilities: Modest but Functional
Video resolution topping out at 1280x720 (720p) at 30 fps for both shows neither camera was designed for serious videography.
The Ricoh’s MPEG-4 format is standard but limited to basic recording modes with no external mic input or headphone jack, precluding pro audio monitoring.
Similarly, the Samsung records in Motion JPEG, which is inefficient by today’s standards and lacks manual exposure control, limiting creative video use.
Neither supports 4K or high frame rate options.
Specialized Photography Uses
Let’s briefly zoom into various photography genres and how these cameras stack up.
Portrait Photography
Ricoh’s face detection and APS-C sensor deliver beautiful skin tones, smooth bokeh at widest apertures, and manual focus support for refined eye focus. Samsung’s smaller sensor and zoom lens offer convenience but yield flatter portraiture.
Landscape Photography
The GXR A16’s superior sensor area and dynamic range allow for better highlight retention and sharpness. The Samsung’s smaller sensor threatens highlight clipping in high-contrast scenes.
Wildlife and Sports
Neither camera promises much here; the Ricoh fares slightly better with manual focus and continuous AF but the burst rate of 3 fps is modest. Samsung’s long zoom is helpful but limited AF and no continuous shooting hamper action photography.
Street Photography
Samsung’s small size and quiet operation benefit candid shots, while Ricoh’s more discreet rangefinder-style design aids compositional control. The Ricoh’s weight and size are a drawback for daily carry.
Macro Photography
Samsung offers close focusing down to 5 cm, suitable for casual macro. Ricoh lacks a dedicated macro mode but close focusing with manual control is possible.
Night/Astro Photography
Ricoh’s higher native ISO (min ISO 200) and larger sensor area outperform Samsung in low light but with limited ISO boost capability on both. Long exposures can be handled but neither is optimized for star shooting.
Video Use
Both suitable for occasional video clips; Ricoh slightly better due to stable MPEG-4 encoding and larger sensor.
Travel Photography
Samsung’s size and weight make it a pure travel buddy, ideal for quick snaps. Ricoh’s sturdiness and better image quality cater to travelers wanting more serious photographic flexibility.
Professional Work
Neither camera meets stringent pro criteria but Ricoh’s RAW file support and manual controls place it well above Samsung’s jpegs-only and automatic systems.
You can see side-by-side real-world images highlighting Ricoh’s detailed texture rendering and Samsung’s decent but softer output, particularly in shaded or indoor scenarios.
