Samsung GX-1S vs Sony RX1R II: A Deep Dive into Two Cameras from Different Eras and Classes

When comparing cameras as distinct as the 2006-era Samsung GX-1S and the 2015 Sony RX1R II, it’s tempting to dismiss the older model outright. But a nuanced look reveals unique qualities each brings to the table, shaped by their era and intended use. Drawing on my extensive hands-on testing experience with hundreds of digital cameras, I’m here to guide you through a detailed comparison between these two very different tools.

Whether you’re a veteran pro curious about vintage gear or a serious enthusiast deciding among modern compacts or DSLRs, this article will help you understand the practical strengths and limitations of both cameras in a variety of real-world photography scenarios. Along the way, we’ll cover core technical differences, usability, imaging performance, and how each handles the diverse demands of photographic genres.

Let’s start by setting the stage with the physical design and ergonomics.

Feel and Form: Size, Ergonomics, and Build

Before launching into specs and performance, it’s important to assess how these cameras feel in the hand - a critical factor influencing shooting comfort and control speed.

Samsung GX-1S: As a mid-sized DSLR with a Pentax KAF lens mount, the GX-1S has a traditional SLR profile that will feel familiar to anyone used to DSLRs. Its body dimensions (125 x 93 x 66 mm) and heft (605g including batteries) give it solid presence without being overly bulky. The ergonomics focus strongly on grip and ease of manual control, with clearly marked dials for shutter priority, aperture priority, and manual exposure modes. The built-in flash is a handy bonus for on-the-go shooting.

Sony RX1R II: By contrast, the RX1R II is positioned as a high-end large-sensor compact. Its body (113 x 65 x 72 mm) and weight (507g) make it notably smaller and more pocketable, though bulkier than average compacts due to its full-frame sensor and fixed 35mm f/2 lens. Its fixed lens means no lens changing but simplifies use and enhances portability. The camera’s build employs premium materials, delivering a rock-solid feel despite the smaller footprint.

From my long-term experience, the GX-1S’s DSLR-style body serves photographers needing rapid lens changes and manual controls, while the RX1R II appeals to those prioritizing compactness without compromising image quality.

Let’s take a glance at the control layouts from above to see direct user interaction differences.

The GX-1S’s top plate houses a classic mode dial and shutter speed dial, along with an integrated LCD status panel - a layout that helps fast decision-making, especially under dynamic conditions like sports or wildlife shooting. The RX1R II’s top controls are more minimalist, focusing on essential dials and buttons to maintain compactness but offering fewer physical controls for direct parameter adjustments.

Imaging Technology: Sensor Size and Image Quality

Arizona’s desert landscapes or a wedding reception’s dim light - image quality is the heartbeat of any serious camera. It’s here where these two differ most profoundly.

• Samsung GX-1S features a 6MP APS-C sized CCD sensor (23.5x15.7 mm), which was respectable in 2006. CCDs deliver pleasing color reproduction but typically lag behind modern CMOS sensors in noise performance and dynamic range.
• Sony RX1R II boasts a 42MP full-frame (35.9x24 mm) back-illuminated CMOS sensor without an anti-aliasing filter, designed for maximum resolution and sharpness. This sensor is a game-changer, offering an enormous 861.6 mm² sensor area - more than double that of the GX-1S - allowing exceptional low-light capabilities, dynamic range, and detail capture.

In real-world testing, the RX1R II delivers images with exceptional clarity, high resolving power, and smooth tonal gradations, even at elevated ISOs up to 25,600 native (extendable to 102,400). The GX-1S holds its own in good light but shows visible noise beyond ISO 800, with limited shadow recovery and dynamic range when compared head-to-head.

The lack of raw testing scores for the GX-1S means we rely on practical experience and legacy reports indicating moderate color depth and shadow detail. Meanwhile, DxOMark’s testing crowns the RX1R II with a high overall score of 97, reflecting stellar color depth (25.8 bits), wide dynamic range (13.9 EV), and excellent low-light ISO sensitivity (3204).

Display and Viewfinding Experience

LCD screens and viewfinders shape your shooting experience profoundly - let’s see how these two cameras compare.

Samsung GX-1S: Comes with a fixed 2.5-inch LCD screen at a modest 210k-dot resolution - typical for its release era but considered crude by today’s standards. Live view is absent, so you rely fully on the optical pentaprism viewfinder, which covers 95% of the frame at 0.64x magnification. While optical viewfinders provide a natural shooting feel, the limited coverage means careful composition and framing is necessary.

Sony RX1R II: Offers a tilting 3-inch LCD with high 1.22m-dot resolution, delivering sharp, bright playback and menu navigation. For viewfinding, it incorporates a high-resolution 0.5-inch electronic viewfinder (EVF) with 100% coverage and 0.74x magnification. The EVF allows precise histogram monitoring, focus peaking, and exposure previews - tools I find indispensable for controlled shooting.

The RX1R II’s electronic viewfinder brings convenience and shooting confidence that surpasses the GX-1S’s simple OVF. However, some purists still prefer optical finders for zero lag and true-to-life scenes.

Autofocus and Speed: How Quickly and Accurately Do They Lock?

Autofocus performance remains critical whether you’re capturing fleeting wildlife moments or street candid shots.

While the GX-1S employs a traditional phase-detection autofocus with 11 points, it lacks face detection and AF tracking capabilities. Continuous AF works reliably but at modest speeds (3 fps), adequate for casual action shots but limiting for fast sports or wildlife photography.

The RX1R II’s hybrid AF system combines contrast- and phase-detection points, providing faster, more accurate focus acquisition. It also supports face detection, an invaluable tool for portraiture, and subject tracking - features that significantly ease capturing moving subjects, albeit continuous shooting tops at 5 fps, still modest for professional sports work.

In my real-world testing, the RX1R II is notably faster locking onto faces and static subjects, though it can struggle slightly with erratic wildlife at a distance due to the fixed lens. The GX-1S, while slower, remains manageable with manual focus lenses thanks to its compatibility with a broad Pentax K-mount lens range.

Versatility in Lenses and Accessories

A crucial factor separating the GX-1S and RX1R II is their approach to lenses and system expansion.

• Samsung GX-1S: Pentax KAF mount offers compatibility with over 150 lenses (including primes, zooms, macro, and specialty optics). Over my career, I’ve found this extensive ecosystem a strong draw for photographers who want flexibility, creative options, or collectibles from legacy glass.

• Sony RX1R II: Equipped with a fixed 35mm f/2 Zeiss lens, renowned for outstanding sharpness and beautiful bokeh. However, no lens swapping restricts versatility, making it best suited to photographers comfortable with a single “normal” focal length or those who prioritize compactness.

External flashes are supported on both cameras, but the RX1R II does not include a built-in flash and relies on shoe-mounted units, while the GX-1S has a built-in flash with multiple modes.

Real-World Use Cases: How Each Camera Excels (or Doesn’t)

Portrait Photography

• Samsung GX-1S: With its 11-point AF and no face detection, nailing critical focus on eyes demands manual skill. Its 6MP sensor limits the ability to crop heavily for tight headshots, and bokeh quality depends on lens choice more than the camera body.
• Sony RX1R II: Thanks to face detection, 25-point AF, and a high-resolution full-frame sensor, portraits look stunning with exceptional skin tone rendition, shallow depth-of-field, and detail. The lens’ f/2 aperture lends romantically smooth background blur.

Landscape Photography

• Samsung GX-1S: APS-C sensor delivers decent resolution but limited dynamic range under contrasty skies. Lack of weather sealing may rule out harsh environments.
• Sony RX1R II: Full-frame sensor excels with broad dynamic range (~14 stops measured), high resolution for large prints, and sharp Zeiss lens gives exquisite corner-to-corner detail, perfect for landscapes.
