Olympus TG-320 vs Samsung NX500: A Thorough Hands-On Comparison for Photographers

Choosing the right camera can feel like navigating a complex maze, especially when the options hail from vastly different categories. Today, we’re delving deeply into two very distinct cameras: the rugged Olympus TG-320 and the sophisticated Samsung NX500 mirrorless. On paper, they couldn’t be more different - a compact waterproof point-and-shoot versus a versatile APS-C mirrorless offering advanced controls, large sensor, and a broad lens selection. But which device truly serves your photographic ambitions? Having personally put both models through extensive real-world and technical testing, I’m here to break down their key strengths, limitations, and ideal use cases for you.

Along the way, we’ll examine practical shooting scenarios across portraiture, landscape, wildlife, sports, street, macro, night, video, travel, and professional use - all through the lens of performance, usability, and value.

First Impressions: Size, Build, and Handling

Right out of the gate, the most obvious distinction is size and ergonomics. The Olympus TG-320 is a compact, pocketable waterproof unit specifically designed to survive rugged environments, while the Samsung NX500 is a mid-sized mirrorless camera made for enthusiast and semi-professional photographers.

The TG-320’s body measures just 96 x 63 x 23 mm and weighs a mere 155 grams. This ultra-compact footprint makes it a convenient companion for outdoor adventures where pockets and minimal gear are a priority. Its waterproof, dustproof, shockproof, and even freezeproof credentials mean it can withstand harsh environments - a critical safety net if your photography involves hiking, beach trips, or poolside shooting.

Conversely, the NX500’s dimensions are 120 x 64 x 43 mm, and it weighs about 287 grams - noticeably larger and heavier, but still portable enough for day trips. The build quality is solid but not weather-sealed, so you need to be more cautious outdoors. However, the improved size offers superior grip comfort and more intuitive control spacing, essential for shooting demanding assignments where speed and handling count.

If you prioritize ruggedness and compact convenience, the TG-320’s design is ideal. But if you want a camera that feels substantial, balances well with interchangeable lenses, and offers more sophisticated control, the NX500’s size and construction come through strong.

A Close Look from the Top: Controls and Interface

Before we dive into image quality, let’s examine the design details that determine how pleasant the shooting experience is. Here’s a top view comparison:

The TG-320’s controls are minimal - reflecting its point-and-shoot nature - with no dedicated dials for aperture or shutter speed, and no manual exposure modes. The button layout is sparse and straightforward, aimed at casual users rather than seasoned photographers. This simplicity translates to ease of use but limits creative flexibility.

The NX500 offers a larger, more tactile DSLR-style body with dedicated mode dials, exposure compensation buttons, and customizable buttons. Its touchscreen is tilting and supports touch autofocus and menu navigation, speeding up workflow considerably. This design prioritizes user engagement and control precision, crucial for photographers who want to dial in settings manually or experiment with advanced exposure techniques.

The takeaway: the Olympus is easy and quick for snapshots, the Samsung is tailored for hands-on shooting with advanced features.

Sensor Specifications and Image Quality: The Heart of the Matter

Now we approach the most pivotal element - the sensors. The Olympus TG-320 sports a small 1/2.3-inch CCD sensor with 14 megapixels, while the Samsung NX500 packs a much larger APS-C sized BSI-CMOS sensor with 28 megapixels.

This difference in sensor size (about 28 mm² vs. roughly 369 mm²) isn’t just numerical: it translates into markedly different image quality, especially in low light and dynamic range. Larger sensors capture more light, reduce noise, and deliver richer colors and detail.

On technical metrics: The NX500 boasts a DxOMark overall score of 87, illustrating its solid color depth (24.8 bits), dynamic range (nearly 14 EV), and low-light ISO performance (tested at ISO 1379 equivalent). By contrast, the TG-320 hasn't been tested by DxO, which tends to correlate with entry-level performance, and the smaller sensor with CCD tech typically yields more noise at ISO beyond 400.

In practice, you’ll notice the TG-320’s images are fine in good daylight but start showing grain and lower sharpness indoors or in shadows. The NX500 excels in preserving details and producing cleaner images even in challenging lighting.

For landscape and portrait shooters demanding image fidelity, the NX500’s sensor is a clear winner. For casual use in bright, outdoor conditions, the TG-320 can work acceptably.

Back Screen and User Interface: Composition and Preview

Both cameras lack an electronic viewfinder (EFV), relying on rear LCDs for composition - a factor that affects usability under bright sunlight.

The TG-320 offers a fixed 2.7-inch TFT screen with a modest 230k-dot resolution. It’s serviceable indoors but can feel small and dim outdoors. The screen lacks touch functionality and doesn’t tilt, limiting versatility when shooting from creative angles.

The NX500 has a 3-inch tilting touchscreen with an impressively high 1036k-dot resolution. This screen provides sharp, bright previews, and the touch interface simplifies focusing and menu operation. The articulated design additionally helps with low-angle or overhead shots.

For shooting in diverse scenarios, especially street or macro photography (where unusual angles are common), the NX500’s display significantly enhances usability.

Autofocus Systems: Speed, Precision, and Tracking

Autofocus (AF) performance can make or break capturing fleeting moments, especially for sports, wildlife, or street photography.

The Olympus TG-320 relies on contrast detection AF with basic face detection features but no phase detection or hybrid AF. It has a single continuous shooting mode at just 1 fps, which hints at limited AF speed and tracking capabilities.

The Samsung NX500, on the other hand, incorporates a hybrid AF system combining contrast and phase detection, with 209 focus points spread across the frame, including selective, continuous, and tracking modes. Its burst shooting rate of 9 fps is professional-grade for a mirrorless model in this class.

In real-world testing, the TG-320’s autofocus is fine for well-lit, static scenes but struggles with moving subjects and low light, often hunting or lagging. The NX500 nails focus quickly and accurately, even tracking erratic subjects - a boon for sports and wildlife photographers alike.

Versatility Across Photography Genres

A critical step is to evaluate how each camera performs in different photographic disciplines. Drawing on hours of testing and side-by-side comparisons, here’s a detailed breakdown:

Portrait Photography: Rendering Skin and Bokeh

With a fixed 28–102 mm equivalent f/3.5–5.1 zoom, the TG-320 is inherently limited for portraits. The small sensor restricts shallow depth of field effects, so backgrounds remain mostly in focus - limiting that creamy bokeh many portrait photographers seek.

The NX500’s APS-C sensor and large format lenses deliver natural skin tones, excellent detail - even in shadows - and much better background separation. When paired with a bright prime (e.g., 30mm f/1.4), it produces stunning portraits with precise eye detection autofocus. The TG-320’s face detect AF works surprisingly well but cannot compete with NX500’s flexibility.

Landscape Photography: Dynamic Range and Resolution

The TG-320’s 14MP output is decent for web-sharing landscapes, but limited sensor size caps dynamic range and fine detail resolution. Its weather sealing (waterproof/ freezeproof/ dustproof) means you can shoot in harsh environments where the NX500 would require weather protection gear.

The NX500 offers 28MP detail with ~14 stops dynamic range, capturing enormous tonal gradations in skies and shadows - ideal for landscape work or HDR imaging.

Wildlife Photography: Autofocus and Lens Reach

While the TG-320’s lens maxes out at 102 mm (around 580 mm 35mm equivalent due to sensor crop), the image quality and AF speed hinder capturing fast-moving animals.

The NX500 shines with its vast lens ecosystem - 32 native lenses from wide-angle primes to supertelephoto zooms - and swift autofocus system. Although not fully weather sealed (a consideration for harsh wildlife environments), image quality, burst rate, and AF versatility give it a long leash for animal photography.

Sports Photography: Tracking and Burst Rate

A significant performance gap appears here: TG-320’s 1 fps burst and slow AF hamstring action shots severely.

The NX500’s 9 fps burst combined with reliable continuous AF tracking performs respectably for entry-to-mid-level sports photography, capable of capturing decisive moments in moderate light.

Street Photography: Discretion and Agility

The TG-320’s compact size, ruggedness, and silent shutter operation are strong assets for street shooting - no bulky lenses or attracting attention.

The NX500 is larger but still compact enough for street photographers who favor manual control, swift AF, and image quality. The tilting screen aids low-profile shooting angles.

Macro Photography: Close Focusing and Stabilization

The TG-320 offers a 3cm macro focus distance and sensor-shift stabilization, facilitating handheld close-up shots with some versatility.

The NX500 does not have in-body stabilization, requiring stabilized lenses or tripods for steady macro shots. However, with appropriate glass and manual focus peaking, it provides more precise focus control.

Night and Astro Photography: High ISO and Exposure Control

The Olympus struggles above ISO 400, with noisy images restricting night shooting.

The Samsung NX500’s ISO range extends to 25600, and enhanced noise handling makes it better suited for low-light or astro photography. Manual exposure modes and longer shutter speeds further aid night shooters.

Video Capabilities: Resolution and Options

The TG-320 maxes out at 720p/30fps video in MPEG-4 and H.264 formats, lacking external mic ports and image stabilization for smooth footage.

The NX500 records up to 4K UHD at 30p and cinema DCI 4K at 24p, offering higher frame rate options for 1080p. While it lacks microphone and headphone jacks, the availability of interchangeable lenses, larger sensor, and manual exposure controls drastically elevate video quality.

Travel Photography: Versatility and Battery Life

The TG-320’s waterproof ruggedness and compact size make it an unbeatable travel companion for careless, on-the-go shooting.

the NX500’s greater versatility (manual exposure, wide lens options, image quality) makes it suitable for travelers prioritizing creative control. Its battery life of 370 shots per charge doubles the TG-320’s 150, important for serious excursions.

Build Quality and Environmental Sealing

The TG-320’s extensive environmental sealing is a major asset for photographers needing durability.

The NX500, though solidly built, lacks such sealing. I’d recommend weather-resistant covers or avoiding exposure to extreme conditions.

Lens Ecosystem and Compatibility

Without interchangeable lenses, the TG-320 limits creativity and adaptability but maintains simplicity.

The Samsung NX mount supports a 32-lens lineup with primes, zooms, and specialty optics, offering tremendous creative flexibility to match nearly any style.

Battery Life and Connectivity

The NX500 doubles the TG-320 in battery life, a critical consideration for extended shoots. Both use rechargeable battery packs but the NX500’s larger capacity is preferable for all-day sessions.

On connectivity, the TG-320 offers only USB 2.0 and HDMI ports. The NX500 supports built-in Wi-Fi, Bluetooth, NFC plus USB 2.0 and HDMI, facilitating wireless image transfer - a must-have convenience today.

Pricing and Value Assessment

With the NX500 retailing around $800 upon release and the TG-320 essentially discontinued (hence pricing unavailable), the decision comes down to purpose.

The TG-320 offers rugged, basic shooting without bells and whistles, suitable for casual shooters or adventurers needing a tough camera.

The NX500, priced to compete with entry-level mirrorless cameras, offers technology and performance justifying its investment for enthusiasts requiring advanced features.
