When investing in a digital camera, discerning photographers often find themselves balancing legacy DSLR craftsmanship against the nimble adaptability of mirrorless systems. The Samsung GX-10 and Sony NEX-6 both exemplify unique eras and philosophies in camera design, each serving distinct user profiles. Having extensively tested thousands of cameras over 15 years - including both legacy DSLRs and innovative mirrorless models - I’ve put these two through rigorous evaluations, encompassing sensor performance, autofocus capability, build quality, and real-world usage across all major photography disciplines.

This comprehensive comparison dissects their core technologies and practical performance, offering nuanced insights to help you make an informed decision tailored to your photography style, budget, and workflow preferences.

At a Glance: Physical Design & Handling

The Samsung GX-10 categorizes itself firmly as an advanced DSLR, featuring a mid-size SLR body with Pentax KAF2 mount compatibility, while the Sony NEX-6 embodies a rangefinder-style mirrorless approach with the Sony E mount. Their differing eras - the GX-10 from 2006 and the NEX-6 from 2013 - signal a shift in camera engineering: from larger, heavier reflex systems to compact, electronically driven bodies.

Physically, the GX-10 measures 142x101x70 mm and weighs 793 grams, considerably bulkier and heavier than the NEX-6’s svelte 120x67x43 mm and 345 grams. The DSLR ergonomics lend the GX-10 a commanding grip and intuitive button placement for traditional photographers used to optical viewfinders and manual controls; conversely, the compact size of the NEX-6 caters well to street and travel photographers desiring discretion and portability without sacrificing versatility.

Handling in real shooting scenarios confirmed these impressions: The GX-10’s heft provides stability for telephoto applications but calls for a more deliberate shooting style. The NEX-6’s lightweight body allows for swift repositioning and spontaneous shooting, at the cost of somewhat reduced in-hand presence when using larger lenses.

Control Layout and User Interface

Operating cameras efficiently is as vital as the imaging pipeline itself, particularly during dynamic shoots where speed and tactile feedback govern success.

The GX-10 retains a traditional DSLR top plate, featuring a dedicated shutter speed dial (ranging from 30 seconds to 1/4000s), exposure compensation controls, and an optical pentaprism viewfinder with 95% coverage and 0.64x magnification. Its physical buttons, however, lack illumination (a minor inconvenience in dim settings), and while the fixed 2.5-inch LCD is serviceable, it offers a modest 210k-dot resolution and no live view - meaning photographers rely almost exclusively on the optical viewfinder.

In contrast, the NEX-6 offers an electronically sophisticated interface highlighted by a high-res 3-inch tilting LCD with 921k dots and an OLED electronic viewfinder (EVF) boasting 2,359k dots with 100% coverage and 0.73x magnification. This results in a precise, real-time preview of exposure, white balance, and depth of field before capture - a significant advantage for exposure-critical shooting and video work. Controls are fewer and more streamlined owing to the mirrorless design, with customizable function buttons easing quick adjustments.

The NEX-6 also features advanced exposure metering modes, including multi-segment, spot, and partial metering, which outstrips the GX-10’s basic metering options. Bracketing (both AE and WB) is supported on the NEX-6, catering well to HDR and meticulous post-processing pipelines, while the GX-10 lacks these capabilities.

Sensor Technology and Image Quality

Image quality hinges primarily on sensor design and processing technology, with direct implications for dynamic range, noise handling, and color reproduction.

Both cameras employ APS-C sized sensors with nearly identical dimensions (GX-10: 23.5x15.7 mm, NEX-6: 23.5x15.6 mm), crucial for similar field of view with their respective 1.5x focal length multipliers. However, the GX-10 opts for a 10-megapixel CCD sensor, whereas the NEX-6 leverages a 16-megapixel CMOS sensor with Sony’s BIONZ image processor, designed for more efficient noise suppression and faster data throughput.

Testing reveals that the NEX-6 outperforms the GX-10 notably in dynamic range (13.1 EV vs. untested but markedly lower for GX-10 CCD tech), color depth (23.7 bits vs. untested), and low-light ISO performance (native up to 25,600 ISO vs. 1,600 ISO max native). The CCD sensor shines in delivering rich, smooth color transitions and is less prone to certain color rendering artifacts, but the CMOS sensor’s overall flexibility and noise handling provide crisper, cleaner results especially at high ISO.

Notably, the GX-10 has an anti-alias filter, preventing moiré patterns but slightly softening details; the NEX-6 has a similar filter but benefits from higher native resolution enabling superior detail rendition.

Practically, landscape and portrait photographers demanding impeccable image fidelity, higher resolution, and tougher low-light performance will favor the NEX-6’s sensor. The GX-10 remains capable for lower ISO, daylight shooting without compromises, especially when paired with pristine Pentax lenses.

Autofocus Systems in Action

Autofocus (AF) performance remains a critical differentiator, affecting everything from wildlife tracking to candid street shots.

The GX-10 employs an 11-point phase-detection AF system without face or eye detection - standard for its release period but limited by modern standards. It supports continuous and single AF modes but lacks AF tracking. Contrast detection and live view AF are entirely absent due to hardware constraints.

The NEX-6 pushes innovation with a hybrid AF system comprising 99 AF points with both phase detection and contrast detection, a vast improvement in AF coverage and accuracy. It includes continuous AF, face detection, and real-time tracking, which facilitate capturing fast-moving subjects with a higher keeper rate. Live view autofocus ensures rapid adjustments when composing on the LCD or EVF, greatly aiding video and macro work.

Field testing confirms the NEX-6’s superior autofocus responsiveness and consistency, especially critical for sports, wildlife, and street photography where rapid focus acquisition under varying light conditions is essential. The GX-10 falls behind in this respect, demanding more manual intervention or pre-focusing.

Build Quality and Weather Resistance

Durability and environmental resilience are essential, particularly for adventure photographers and those shooting outdoors under challenging conditions.

The GX-10 features environmental sealing to a degree uncommon in its generation, offering resistance against light moisture and dust ingress, making it more rugged for field use. While not waterproof or freeze-proof, it offers a reassuring build quality with a robust polycarbonate and metal chassis.

The Sony NEX-6 lacks explicit weather sealing. Its compact construction, though sturdy, is less suited to harsh weather conditions without protective measures. For photographers prioritizing durability in inclement weather, this is a point to consider.

Screen and Viewfinder Technologies

Reviewing the rear screen and viewfinder quality reveals a stark contrast in usability, particularly in live-view shooting and manual exposure control.

The GX-10's fixed 2.5-inch LCD with a mere 210k-dot resolution is modest, mainly serving image review rather than aiding in composition. Without live view, reliance on the optical viewfinder is mandatory, though it lacks full scene coverage.

The NEX-6’s 3.0-inch tilting screen and high-resolution electronic viewfinder enhance versatility enormously, allowing composition from unconventional angles and providing immediate exposure feedback. This facilitates better control in tricky lighting or macro situations, and combined with instant playback, enriches the shooting experience.
