Olympus E-620 vs Samsung Galaxy NX: A Hands-On Comparative Journey Through Two Distinct Cameras

When I first sat down to compare the Olympus E-620 and the Samsung Galaxy NX, I knew I was looking at two very different beasts. One harkens back to the DSLR era with a compact body and sensor stabilization, while the other ventures boldly into mirrorless territory with a tech-forward hybrid of camera and Android-powered smart device. Over my 15+ years testing cameras, I’ve come across many such pairs that, on paper, seem incomparable. Yet, members of both camps often compete for the same user attention: photography enthusiasts seeking an accessible, versatile camera with solid image quality and features.

In this extended hands-on comparison, I’ll dive deep into their real-world performance, technical strengths and trade-offs, and carefully weigh who each camera truly serves best. Whether your passion lies in portraits, landscapes, wildlife, or video, this review will provide both broad strokes and granular insights to aid your camera shopping decisively.

First Impressions: Ergonomics and Handling in Your Hands

Even before pressing the shutter, how a camera feels profoundly impacts one’s shooting joy and creativity. The Olympus E-620 is a compact DSLR from 2009, designed to be approachable yet offer enough control to satisfy ambitious new photographers. The Samsung Galaxy NX, meanwhile, emerged in 2013 as a mirrorless with a striking tablet-like fixed touchscreen and Android OS integration.

The Olympus E-620’s 130 x 94 x 60 mm body and 500g weight make it pleasantly manageable - compact for a DSLR but still reassuringly solid. The articulating 2.7-inch screen, while modest by today’s measures, swivels and tilts impressively, great for high and low angle shots. The recessed grip fits hands securely, and the modest button layout invites direct access to essential exposure controls. It feels like a classic camera in how much “manual” tactile interaction it supports, positively encouraging a deliberate workflow.

In contrast, the Samsung Galaxy NX weighs in at 495g and stretches longer but thinner (137 x 101 x 26 mm), largely due to its integrated 4.8-inch fixed touchscreen. This form factor blurs a bit, resembling a hybrid between an SLR-style camera and a tablet. The absence of an articulating screen and the slim, flat body design mean that holding it steady requires a bit more care. One-handed operation isn’t as natural as with the E-620. Nor does the Galaxy NX have a traditional grip, which I found made longer shoots more tiring. However, the touchscreen feels responsive and intuitive for menu navigation.

Both cameras lack modern weather sealing, so outdoor shooters should treat them with basic protective care. The Olympus is missing illuminated buttons and wireless features, whereas Samsung jumps ahead with built-in Wi-Fi and GPS, catering to connected photographers.

Under the Hood: Sensor Specs and Image Quality Breakdown

The sensor is the heart of any camera, crucial to understanding real image quality and low-light capabilities. The Olympus E-620 sports a Four Thirds CMOS sensor measuring 17.3 x 13 mm with 12MP resolution - a mature design in its day, but modest by today’s standards. The Samsung Galaxy NX is built around a 23.5 x 15.7 mm APS-C CMOS sensor and boasts a considerably higher 20MP resolution.

These size and resolution disparities alone set different performance expectations. The APS-C sensor offers approximately 64% more surface area to gather light, translating into intrinsically better dynamic range, improved noise control, and finer detail rendering at similar or higher ISOs.

When I analyzed DXO Mark overall scores, Olympus’ E-620 rated at 55 points, scoring notably in color depth (21.3 bits) and respectable dynamic range at 10.3 EV, but lagging behind in low-light ISO performance (score 536). Unfortunately, the Galaxy NX wasn’t officially tested on DXO Mark, but based on the sensor specs and Sony-based DRIMe IV processor lineage, I observed cleaner images at high ISO settings in real shooting than the older Olympus could muster.

Testing both side-by-side under diffused window light, the Galaxy NX’s images revealed superior clarity and better noise suppression in shadows. Olympus images retain excellent color accuracy and smoother gradations, partly due to the TruePic III+ image processor designed to optimize Four Thirds sensor output. However, the difference in the APS-C sensor’s pixel density and signal-to-noise architecture still gave Samsung an edge for demanding lighting conditions.

The Viewfinder and Screen: Navigating Your Frame

The evolved interface experience significantly influences user confidence and comfort. The Olympus E-620 features a traditional optical pentamirror viewfinder, offering about 95% coverage and 0.48x magnification - typical for entry-level DSLRs of its time. It has a charmingly analog feel, crucial for photographers who prefer composing with the naked eye rather than a digital preview.

Samsung’s Galaxy NX mandates an electronic viewfinder (EVF) due to its mirrorless design, although it foregoes a dedicated viewfinder eyepiece and relies mainly on the large rear LCD touchscreen for framing and settings adjustment.

The Olympus’s top plate hosts clear physical dials and buttons for shutter speed, aperture, metering, and ISO - replete with tactile feedback I found especially useful during active shooting. The Galaxy NX’s touch-based interface is more minimalistic, emphasizing touchscreen controls with fewer physical buttons, which can feel limiting if you depend on quick manual overrides.

Further illustrating this interface difference is the LCD screen comparison:

The Olympus’s 2.7-inch fully articulated HyperCrystal LCD may seem dated but excels in flexibility. Conversely, the Galaxy NX’s large fixed 4.8-inch HD TFT LCD offers superb resolution (922K dots) with touch input, benefiting live view framing and playback. However, without an articulating mechanism, it can be difficult to shoot from awkward angles.

Autofocus and Shooting Speed: Catching Life’s Fleeting Moments

Both cameras provide face detection autofocus - a welcome feature - but their autofocus (AF) implementations differ significantly.

The E-620 sports a 7-point AF system with cross-type elements, phase-detection AF for rapid lock-on, and offers single, continuous AF, and selective-area AF. However, AF tracking is absent, showing its era’s technological limits.

Samsung’s Galaxy NX has an under-documented AF point system but utilizes contrast detection combined with phase detection on its hybrid CMOS sensor. Its touch AF makes manual focusing more intuitive on the screen, but continuous AF functions are limited and lack multi-area or tracking sophistication.

Rapid shooting speeds set the cameras apart:

• Olympus E-620 shoots at 4 frames per second (fps)
• Samsung Galaxy NX captures 9 fps - more than double

For sports and wildlife, this burst speed difference is critical. In my field tests photographing local birds, the Galaxy NX better captured fast wingbeats thanks to its fast firing rate, while Olympus sometimes missed key action frames.

Lens Ecosystem and Mount: Building Your Creative Toolkit

The mount system heavily influences a camera’s adaptability and long-term use.

Olympus E-620 rides the Four Thirds mount system, with roughly 45 lenses available spanning primes and zooms from various manufacturers. The 2.1x crop factor results in a substantial narrow field of view, favoring telephoto reach but posing challenges for ultra-wide landscapes.

Samsung Galaxy NX uses the Samsung NX mount, providing around 32 lenses at launch, though the lens selection is more limited than Olympus’s mature Four Thirds ecosystem. Its 1.5x crop factor balances wide-angle capabilities without excessively sacrificing telephoto length.

If you already own or plan to expand your system affordably, the Olympus ecosystem may provide better lens variety - especially for specialized lenses like macros and ultra-wide zooms.

A Make-Or-Break Factor: Image Stabilization and Low-Light Performance

Olympus’s sensor-based image stabilization (IBIS) is a significant asset. The E-620’s IBIS helps reduce shake by physically compensating for handheld motion, valuable in still situations and slow shutter speeds. This feature, paired with sharp Four Thirds lenses, produced sharp results in my handheld night shots where shutter speeds extended below 1/30s without blurring.

The Samsung Galaxy NX lacks built-in stabilization. While some NX lenses incorporate optical stabilization, this inconsistency means you’ll depend more heavily on tripod use or faster shutter speeds in dim environments.

Video Capabilities: From Snapshots to Moving Stories

Olympus E-620, despite being an entry-level DSLR, offers no video mode - an obvious limitation in today’s hybrid shooting culture.

Samsung Galaxy NX is one of the more interesting early mirrorless cameras embracing video. It supports:

• Full HD 1920x1080 at 30fps recording
• HD 720p, VGA, and lower resolutions
• MPEG-4 and H.264 compression
• External microphone and headphone jacks for advanced audio control
• HDMI output for monitoring

During my video tests, the Galaxy NX produced clean, vibrant footage with manageable rolling shutter. The touchscreen controls on the NX allow quick focus pulls and exposure adjustments. However, the lack of built-in image stabilization on the sensor can make handheld video shakier, so I recommended using optical stabilization lenses or gimbals.
