A Tale of Two Cameras: Overview and Initial Impressions

The Olympus XZ-2 iHS is a refined compact designed with enthusiast photographers in mind who want a pocket-friendly unit that delivers creative control, manual focus options, and a fast lens with sensor-shift stabilization. Its 1/1.7" CMOS sensor with 12MP resolution supports RAW shooting, combined with a bright f/1.8-2.5 zoom, tilting touchscreen, and built-in Wi-Fi via Eye-Fi card compatibility.

Conversely, the Samsung GX-1S, reflecting DSLR design philosophy from the mid-2000s, is a bulkier but far more flexible system camera with an APS-C CCD sensor at 6MP resolution. Using the Pentax KAF lens mount, it supports a wide lens ecosystem including many legacy optics. Its optical pentaprism viewfinder, shutter speeds up to 1/4000s, and traditional DSLR controls appeal to photographers favoring tactile manual operation.

Let’s start by comparing the fundamental physicality of these two models, which influences handling, portability, and ergonomics.

Handling and Design: How They Feel in Your Hands

Size and Weight
The Olympus is compact and lightweight at just 346 grams and a footprint of 113 x 65 x 48 mm, easily slipping into even modest pockets - a decisive advantage for travelers or street photographers prioritizing discretion and portability. The Samsung GX-1S weighs nearly twice that at 605 grams and measures 125 x 93 x 66 mm. Its heft reflects a sturdy DSLR chassis.

Control Layout and User Interface
The Olympus features a 3" tilting touchscreen with 920k dots, granting intuitive touch AF and review which elevates usability, especially for novices or those seeking quick framing adjustments from lower angles. The camera’s physical controls are minimalistic yet logically arranged, catering to a hybrid manual/automatic operation experience.

Meanwhile, the Samsung GX-1S relies on a smaller 2.5" fixed LCD with only 210k dots resolution, lacking touchscreen capability and live view entirely, as was typical for cameras of its generation. Its top-plate displays and numerous physical dials offer direct access to aperture, shutter speed, and exposure compensation, which seasoned users may find quicker to adjust without digging into menus.

From an ergonomic perspective, the GX-1S provides a larger grip and more pronounced buttons, beneficial for stable shooting during extended use, while the Olympus’s compactness boosts mobility but potentially at the cost of one-handed operation comfort for large hands.

Sensor and Image Quality: The Heart of the Matter

At the core of any camera’s imaging potential lies its sensor. The Olympus XZ-2 iHS employs a 1/1.7” CMOS sensor with dimensions 7.44 x 5.58 mm, equaling an area of approximately 41.5 mm², sporting 12MP resolution with an anti-aliasing filter. The Samsung GX-1S wields the older yet much larger APS-C CCD sensor, measuring 23.5 x 15.7 mm or roughly 369 mm² - almost 9 times the sensor area of the Olympus and offering a 6MP output with finer pixel pitch.

Dynamic Range and ISO Performance
While CCD sensors excelled decades ago with cleaner color depth and low noise at moderate ISOs, technological advances in CMOS have since overtaken them, especially in dynamic range and high ISO capability. The Olympus’s DXO lab scores specify an overall 49, color depth of 20.4 bits, dynamic range of 11.3 EV, and low-light ISO roughly at 216. Though modest by today’s standards, the CMOS sensor with back-illuminated tech and modern processing compensates surprisingly well in noise control beyond ISO 800, where the Samsung’s aging CCD sensor falls behind noticeably.

The GX-1S’s maximum native ISO is 3200, but real-world testing exhibits less usable data beyond ISO 800 due to amplified noise and lower dynamic range typical of CCDs.

Resolution and Detail
The Olympus’s higher pixel count at 12MP theoretically allows for slightly greater detail extraction and cropping flexibility despite the smaller sensor. However, the Samsung’s sensor captures larger pixels, which can favor smoother tonal gradients and less chroma noise per pixel but at the expense of lower resolution.

For landscape and portrait work demanding fine detail and smooth tonal rendition, the Olympus delivers crisper images out of the box with the caveat of increased diffraction starting around f/5.6 due to smaller sensor size.

Color Rendition and White Balance
Both cameras support custom white balance, with Olympus providing limited WB bracketing - missing entirely from the Samsung. Skin tones captured by the Olympus render with slightly more vibrancy and saturation, which benefits portraits with natural warmth, while the Samsung leans towards flatter, more subdued colors requiring more post-processing correction.

Autofocus Systems: Precision vs. Legacy

Autofocus is critical to most genres, especially fast-moving sports and wildlife photography. The Olympus XZ-2 iHS relies on a contrast-detection AF system with 35 selectable points and built-in face detection but lacks phase-detection or advanced tracking. Its speed is respectable for a compact but cannot match DSLR performance. The lack of continuous AF and tracking limits its use for fast-moving subjects.

The Samsung GX-1S shines in this area with a phase-detection AF system featuring 11 focus points capable of continuous AF and selective AF area modes, enabling better tracking of moving subjects. Although 11 points are modest by modern standards, when combined with the DSLR’s larger sensor and interchangeable lens AF motors, it offers superior speed and accuracy.

Build Quality and Weather Resistance

Neither camera offers extensive environmental sealing. Both lack dustproof, waterproof, shockproof, crushproof, and freezeproof features. The Samsung’s bulkier DSLR design with pentaprism may yield a sturdier feel in prolonged outdoor professional use, while the Olympus trades ruggedness for portability.

LCD Screen and Viewfinder: Composing Your Vision

The Olympus’s 3" tilting touchscreen (920k dots) grants flexibility for low or high angles and more interactive focus selection, elevating situational creativity, especially for macro or street photography.

The Samsung GX-1S includes an optical pentaprism viewfinder covering 95% of the frame at 0.64x magnification, standard for DSLRs of its time. This optical viewfinder offers an unlagged, true-to-life framing experience desirable for sports and wildlife photographers prioritizing precision composition.

Neither camera offers an electronic viewfinder by default, although Olympus supports an optional external EVF, which can be a convenience for bright daylight shooting.

Lens Ecosystem and Compatibility

Lens selection dramatically affects photographic versatility. The GX-1S utilizes the Pentax KAF mount, recognized for a mature lineup of over 150 lenses including modern autofocus primes, telephotos, specialty optics, and even legacy manual focus lenses via adapters. This expands the Samsung’s utility beyond the camera body’s baseline.

In comparison, the Olympus XZ-2 iHS features a fixed zoom zoom lens covering a 28-112 mm equivalent range (4x zoom) with a fast aperture of f/1.8-2.5. The lens’s macro capabilities (1 cm minimum focus distance) are excellent for close-ups and detail shots. However, the fixed lens limits flexibility in adapting to various shooting scenarios without carrying additional bodies.
