Choosing the right camera involves balancing numerous considerations - sensor size, ergonomics, autofocus, durability, lens options, and more - tailored to your creative priorities and shooting scenarios. In this in-depth comparison, I dissect two very different cameras aimed at distinct user bases: the Olympus Stylus Tough TG-870, an ultracompact rugged camera designed for adventurous and casual shooters, and the Samsung NX100, a pioneering entry-level mirrorless from 2010 targeted toward enthusiasts looking for flexibility and image quality. Both cameras have unique strengths and limitations shaped by their designs and eras, and as someone who has meticulously tested thousands of more recent and legacy models, I’ll leverage hands-on expertise and technical analysis to help you understand which camera might best suit your photographic ambitions today.

First Impressions and Handling: Size, Ergonomics, and Control Layout

When evaluating cameras, first impressions heavily influence the user experience - how a camera feels in the hand, how intuitively controls are placed, and how portability relates to intended use.

The Olympus TG-870 clocks in as an ultracompact rugged compact camera with dimensions of 113 x 64 x 28 mm and a lightweight 221 g body, designed to be durable and easy to carry anywhere - even underwater or in harsh environments. Its boxy shape with textured grips makes handling secure without adding extra bulk. The Samsung NX100, by contrast, is a classic rangefinder-style mirrorless camera measuring 120 x 71 x 35 mm and weighing 282 g, reflecting early mirrorless ergonomic sensibilities with a slightly larger grasp, a traditional shutter button placement, and a more substantial build aimed at enthusiasts.

The TG-870’s more minimalistic control set caters to straightforward point-and-shoot use, lacking advanced exposure modes or manual control wheels. The Samsung NX100 incorporates a more conventional exposure dial system with dedicated shutter and aperture priority modes, giving owners broader exposure control - a crucial factor for photographic creativity beyond automatic presets.

From the top view perspective, Olympus has prioritized waterproof sealing and ruggedness over dials, favoring a simple shutter release and zoom controls, whereas Samsung’s NX100 exhibits a more traditional control cluster with mode dials and AF settings.

In sum, if portability, durability, and ease-of-use rank highest in your priorities, the TG-870 is ergonomically optimized for active, on-the-go shooting. For those wanting tactile dials, manual exposure control, and a more traditional photographic experience, the NX100 stands out despite its older design.

Sensor Technology and Image Quality: Compact vs APS-C

A key differentiator is the sensor size and technology, with fundamental impacts on image quality, low-light capability, dynamic range, and depth of field control.

Olympus TG-870's 1/2.3-Inch BSI-CMOS Sensor

The TG-870 uses a 16 MP backside illuminated (BSI) CMOS sensor in the small 1/2.3" size format (6.17 x 4.55 mm, 28.07 mm² sensor area), typical for compact waterproof cameras. While the BSI tech enhances light-gathering efficiency over older front-side illuminated designs, the sensor’s physical diminutiveness imposes limits on ISO performance and dynamic range. This size is around a tenth the surface area of APS-C, so it inherently struggles with noise at mid to high ISOs.

Image resolution maxes at 4608 x 3456 pixels, delivering perfect suitability for casual prints and social sharing, but the smaller sensor restricts shallow depth of field effects and fine detail rendition compared to larger formats.

Samsung NX100's APS-C CMOS Sensor

In contrast, the NX100 features a 15 MP APS-C sized CMOS sensor measuring 23.4 x 15.6 mm with 365.04 mm² area - over 13 times larger than TG-870's sensor. This significantly larger sensor offers far superior light-collecting ability, resulting in better low-light performance, an expanded dynamic range of 10.7 EV (according to DxO Mark), and a broader color depth of 22.6 bits. The APS-C sensor affords much cleaner images at ISO ranges up to 3200 and maintains detailed textures ideal for prints well beyond A3-sized formats.

The NX100’s sensor benefits from Samsung’s DRIMe processor, which - although now dated - still provides solid noise reduction and color processing. The inclusion of an anti-aliasing filter limits fine moiré but helps keep images clean.

Autofocus and Focusing Capabilities

Autofocus (AF) system effectiveness is a vital consideration, especially for dynamic subjects or low-light shooting.

Olympus TG-870: Contrast-Detection AF with Face Detection

The TG-870 relies on a contrast-detection AF system with face detection and multiple AF areas but no phase-detection AF. With 7 fps continuous shooting, it supports autofocus tracking for moving subjects at a modest pace - adequate for casual action shots or wildlife at a distance but prone to hunting in dim conditions.

Its macro focusing range impressively reaches just 1 cm, allowing for close-up shots with ample flexibility. However, lack of manual focusing and focus bracketing limits creative control for advanced macro work.

Samsung NX100: 15 Contrast-Detection AF Points with Manual Focus

The NX100’s AF system includes 15 contrast-detection points with selective and center weighting but no phase detection or AF tracking. Continuous shooting at 3 fps is slower, reflecting its 2010-era focus system and sensor readout speed.

Uniquely for this pair, the NX100 supports manual focusing, crucial for demanding shooting conditions or precise focusing in macro and studio work. The availability of an interchangeable lens system combined with aperture control on lenses bolsters creative depth control and focusing refinement.

Build Quality and Environmental Durability

Durability and weather resistance are areas where these cameras diverge notably, reflecting their design intentions and target user base.

The Olympus TG-870 is purpose-built for severe conditions, boasting waterproofing up to 15 meters, dustproof construction, shockproofing against 2.1m drops, crushproof rating up to 100 kgf, and freeze-proof capability to −10 °C. This robust build suits adventurers, underwater shooters, and outdoor enthusiasts requiring a camera that works where typical DSLRs or mirrorless might be at risk.

Conversely, the Samsung NX100 lacks any explicit environmental sealing or weather resistance features. Its rangefinder-styled body is designed primarily for general-purpose shooting in controlled environments or light outdoor use.

Hence, for beach, snorkeling, hiking, or winter sports photography, the TG-870’s ruggedness is a compelling advantage.

Display, Viewfinder, and User Interface

Screen quality and viewfinder availability directly affect composition comfort and image review in field conditions.

Both cameras feature 3-inch LCD screens; however, the Olympus TG-870’s screen tilts, enabling more flexible shooting angles and facilitating self-recording or awkward perspectives, albeit without touchscreen functionality. It has a fairly high resolution of 921k dots, yielding clear, sharp previews.

The Samsung NX100 employs a fixed 3-inch VGA AMOLED display with 614k dots - lower resolution by today’s standards but with impressively rich contrast and color saturation due to AMOLED tech.

Neither camera includes an electronic viewfinder as standard; however, the NX100 offered an optional EVF accessory, which might appeal to compositions in bright sunlight, where LCDs struggle.

Both cameras utilize built-in menu systems navigable via buttons - no touch capabilities - which can feel archaic compared to modern UIs but offer reliable control in wet or gloved scenarios for the TG-870.

Apertures range from f/3.5 to f/5.7, sufficient for casual shooting but limiting shallow depth-of-field effects and gathering less light in dim environments.

Its macro capability down to 1 cm is notable for close-up enthusiasts within the fixed optical design constraints. However, the inability to swap lenses restricts compositional flexibility.

Samsung NX100: Interchangeable Samsung NX Mount with 32 Compatible Lenses

The NX100 shines as an interchangeable mirrorless system with 32 native Samsung NX lenses available, including fast primes, wide-angle, telephoto, macro, and zoom lenses. This extensive ecosystem enables users to tailor their setup precisely to portraiture, landscape, wildlife, or macro photography.

The APS-C sensor benefits from lenses designed to exploit its size, delivering better image quality and depth control than the compact fixed-lens setup. Initial kits often came with an 18-55mm f/3.5-5.6 zoom, but numerous faster primes (such as a 30mm f/2 or 50mm f/1.4) are accessible for low light and bokeh-rich portraits.

This lens flexibility enhances the NX100’s longevity and creative versatility, making it a more futureproof investment for serious enthusiasts.

Burst Shooting, Buffer, and Shutter Speed Range

Action photography and capturing dynamic moments rely on continuous shooting performance and shutter speed capabilities.

The Olympus TG-870 supports a faster continuous shooting speed of 7 fps at full resolution, which is impressive for a compact rugged camera, suitable for casual sports, family snapshots, or wildlife in daylight. However, shutter speeds max out at 1/2000s, limiting options for extremely bright conditions or creative use of ultra-fast shutter.

The Samsung NX100 offers 3 fps continuous shooting, reflecting its older processor and sensor readout speeds, but provides longer shutter speeds ranging from 30 seconds to as fast as 1/4000s, allowing for long exposure photography (night sky, light painting) and action freeze with greater precision.
