Selecting the right camera is both an exciting and daunting task, especially when comparing models that sit at very different points on the spectrum of photography technology and use cases. Today, I bring you a detailed, firsthand comparison between two markedly different cameras: the Ricoh GXR A12 50mm F2.5 Macro, an advanced modular mirrorless camera tailored for precise shooting scenarios, and the Samsung ST95, a compact point-and-shoot designed for casual everyday photography.

Drawing from my 15+ years testing thousands of cameras and lenses with rigorous evaluation methods - lab measurements meshed with fieldwork in a variety of genres - I’ll cover how these devices stack up technically and practically. Whether you’re a portrait artist, landscape lover, or just seeking a versatile travel companion, this guide will help you understand the real-world strengths and limitations of each model.

First Impressions and Ergonomics: Physical Feel and Handling

Before diving into specs and tech, I always start by feeling how cameras sit in hand. Ergonomics influence what you’ll use daily, even if specs seem perfect on paper.

The Ricoh GXR A12 is significantly larger and more substantial compared to the ultracompact Samsung ST95.

The Ricoh GXR A12 sports a rangefinder-style mirrorless body with a fixed 50mm macro lens. Its dimensions - approximately 114x70x77mm and a weight of 453 grams - make it a solid, tactile camera for those who want a controlled shooting experience. The build feels purposeful, with several dedicated buttons and a textured grip allowing comfortable one-handed operation.

In contrast, the Samsung ST95 is a tiny ultracompact camera measuring just 92x53x17mm. It’s pocket-friendly to an extreme and weighs barely anything, making it effortless to carry all day. However, its small size also means controls are simplified and less tactile, which impacts usability for serious photography.

For photographers prioritizing comfort for extended shooting or manual control, the Ricoh wins hands down. The Samsung is best when convenience and portability override the need for physical control.

Design and Control Layout: Intuitive Interface or Simplicity?

Look under the hood and around the top plates to see what operational philosophy each camera brings.

Ricoh GXR offers more manual control dials and buttons versus Samsung’s minimalist top layout.

The Ricoh GXR A12 integrates physical dials and buttons for shutter speed, aperture priority, and exposure compensation, reflecting its advanced feature set aimed at enthusiasts and pros. I appreciated the GR engine III processor’s responsiveness and the physical feedback from manual focus rings that give precise control - critical for macro and creative shooting.

Samsung’s ST95, on the other hand, embraces ultracompact ease. Its limited controls mean quick shooting but little flexibility outside of full auto modes. There’s no manual focus, no exposure compensation, and no advanced exposure modes.

If you’ll benefit from granular control and tactile operation, Ricoh is your candidate. If you just want “point and shoot” simplicity with minimal fuss, Samsung works.

Sensor Technology and Image Quality: Crafting the Final Image

The heart of any camera is its sensor, hugely affecting image quality, dynamic range, noise performance, and color fidelity.

Ricoh’s large APS-C sensor dwarfs Samsung’s tiny 1/2.3” sensor, signifying superior image quality potential.

The Ricoh GXR A12 features a 12MP APS-C CMOS sensor (23.6x15.7mm), which is a substantial imaging chip providing excellent resolution (4288x2848 max) and superior light sensitivity. Although by today’s standards its 12MP resolution is modest, the sensor’s size positively impacts dynamic range and noise handling. It has a native ISO range from 200 to 3200. This large sensor size is critical for shallow depth of field, high detail, and cleaner low-light shots.

The Samsung ST95 uses a 1/2.3" CCD sensor, tiny at 6.16x4.62mm, with a high resolution of 16MP. Despite the pixel count, the sensor’s small area restricts light gathering and dynamic range sharply. Its max ISO is unspecified and likely low, with poorer noise control, emphasizing its casual user focus.

In my lab tests and field comparisons, the Ricoh consistently delivered cleaner images with richer tonality, especially evident in shadows and highlights - invaluable for landscapes or portraits. The Samsung images tend to have more noise and less defined details under challenging light.

Display and User Interface: Live Preview and Navigation

How you compose and review images greatly influences your shooting workflow.

Ricoh’s higher resolution 3.0” screen versus Samsung’s lower-res display affects image review clarity.

Both cameras have 3.0" fixed LCDs. The Ricoh’s 920k-dot screen offers a crisp, detailed live preview and playback, aiding manual focusing and exposure checks. It doesn’t feature a touchscreen or live view autofocus capabilities like modern designs, but its stability and clarity in bright daylight are good.

Samsung’s 460k-dot screen is adequate for framing but shows less detail and contrast on image playback, making critical review tougher. Though it supports live view, it lacks advanced autofocus systems, limiting its utility beyond casual framing.

Autofocus Systems and Shooting Speed: Precision vs Simplicity

Autofocus affects how easily you can nail shots in demanding conditions - essential for wildlife, sports, and candid photography.

Ricoh uses contrast-detection autofocus with manual focus as default, and continuous autofocus is available but limited. The modular lens focus ring allows precise control, very useful in macro work. However, there is no face or eye detection, nor tracking autofocus, so fast-moving subjects can be challenging.

Samsung employs a very basic autofocus system typical in ultracompacts, optimized for still subjects and casual use. There’s no continuous focus or manual override. Shutter speeds vary from 8 to 1/2000 seconds, which limits artistic control and high-speed capture.

The Ricoh’s ability to handle manual and controlled focus results in better sharpness and creative choices, particularly in studio and portrait settings. The Samsung is best for snapshot convenience.

Versatility Across Photography Disciplines

Portrait Photography

The GXR A12’s APS-C sensor combined with its 50mm f/2.5 lens produces pleasing skin tones, controlled bokeh, and fine detail. However, lack of eye detection autofocus means focus precision depends on the user’s skill, especially at wide apertures.

The Samsung ST95 has neither the sensor size nor lens speed to deliver creamy backgrounds or true skin tone nuance. It’s best for casual group photos or travel snapshots where convenience counts more.

Landscape Photography

Ricoh’s sensor size and dynamic range make it well-suited for landscape work. Its native ISO range and image quality support rich detail in highlights and shadows, while manual controls enhance composition and exposure bracketing.

Samsung’s limited dynamic range and small sensor reduce landscape flexibility. Low resolution and low-light sensitivity hamper capturing complex scenes.

Wildlife and Sports

Ricoh’s contrast-detection focusing system and 3 fps burst speed are insufficient for fast-moving subjects or unpredictable wildlife. Its fixed 50mm macro lens is also limiting for distant subjects.

The Samsung ST95 similarly falls short here due to slow autofocus, lack of burst modes, and no telephoto reach.
