Pentax WG-3 GPS vs Samsung DV300F: An Expert’s Real-World Compact Camera Showdown

Choosing the right compact camera can feel like walking through a jungle of specs and brand promises, especially when two models look similar on paper but serve distinct photographic needs. Today, I’ll pit two intriguing contenders from slightly different corners of the compact camera market against each other: the rugged, adventure-ready Pentax WG-3 GPS and the sleek, everyday pocket shooter Samsung DV300F. Based on thousands of cameras I’ve tested, including specialized compacts like these, I’ll break down their performance across major photography genres, dissect real-world usability, and ultimately answer: who should buy which and why.

Buckle up, because we’re going deep - from sensor tech and autofocus wizardry to ergonomics, image quality, and even battery life.

Getting to Know the Cameras: Build, Size, and Controls

Before you raise your eyebrows at specs, let’s start with the tactile experience - how these cameras sit in your hands matters as much as megapixels.

The Pentax WG-3 GPS is a tough cookie: built like a mini tank at 125x64x33mm and weighing a solid 238g. It's shockproof, freezeproof, crushproof, waterproof, and dustproof - seriously, this camera laughs in the face of Mother Nature’s worst moods. That makes it a perfect travel buddy for hikers, beachgoers, or anyone who might batter their gear a bit.

On the flip side, the Samsung DV300F is far more modest and pocket-friendly, measuring 95x57x18mm and weighing 133g. It’s sleek and lightweight, designed to disappear into your jacket pocket or purse. But it offers no ruggeding - no weather sealing - so it’s best kept away from sandstorms or sudden downpours.

Hold this right here: the Pentax sports chunky, grippy controls with some clubs for your thumbs, whereas the Samsung is more minimalistic, with a compact top plate and slim buttons. Neither has a viewfinder, relying exclusively on their 3-inch LCDs for framing. The Pentax WG-3 GPS’s controls might be a welcome relief for people who want dedicated buttons and a robust grip when outdoors, while Samsung’s design leans toward simplicity and portability.

Under The Hood: Sensor, Image Quality, and Processing

Specs tables are useful, but image quality comes down to more than numbers. I ran both cameras through standardized test charts and real-world shoots in my studio and outdoors to assess their sensor performance.

Both are equipped with a 1/2.3" sensor measuring roughly 6.17x4.55mm - a common size for compacts. Both cameras have a 16MP resolution with anti-aliasing filters, but the similarities end at megapixels and sensor real estate.

Pentax WG-3 GPS uses a more modern BSI-CMOS sensor, which offers better light-gathering abilities and thus usually better performance in low light and higher ISO settings.

Samsung DV300F, shutterbugs, runs a traditional CCD sensor of the same size, which historically gives punchier colors but tends to struggle a bit more with noise at higher ISO.

From my tests:

• Dynamic range: The Pentax’s CMOS sensor delivered noticeably better highlight and shadow detail recovery. In landscape scenes, this advantage preserved clouds without blowing them out and retained textures in shaded areas.

• Noise and high ISO: The Pentax produced cleaner images at ISO 800 and above, thanks to sensor tech and image processing algorithms. Samsung images started showing luminance noise and color speckles around ISO 400.

• Color rendering: Samsung captured slightly richer but sometimes over-saturated tones, which may appeal to casual shooters keen on punchy JPEGs straight out of the camera. Pentax was more neutral and true-to-life, better for those wanting to tweak in post.

Truthfully, neither is a top performer compared to today’s advanced compacts or interchangeable-lens cameras - but between these two, the Pentax WG-3 GPS edges ahead for raw image quality and flexibility.

The LCD and User Interface: Seeing Your Shot

Neither offer viewfinders, but their rear LCDs differ subtly.

Both cameras sport fixed 3" LCDs with roughly 460k-dot resolution.

• Pentax’s screen has an anti-reflective coating, which helps a bit in sunlight but still struggles under direct bright outdoors lighting.
• Samsung’s LCD is a classic TFT without special anti-glare treatment, somewhat less usable in bright conditions.

Neither screen is touch-enabled, which, given their respective ages and market positioning, is not a surprise.

In-hand navigation: The Pentax menus feel a touch more logical and fluid, aided by well-labeled buttons, while Samsung’s interface is simpler but sometimes buried in nested menus.

Autofocus and Performance: Tracking the Action

Let’s discuss one of the most important real-world factors, especially for sports and wildlife photography: autofocus.

The Pentax WG-3 GPS boasts 9 autofocus points with contrast-detection AF, face detection, and even AF tracking (though only single-shot AF is available). Its focal range of 25-100mm (35mm equivalent) with a bright f/2 at the wide end aids faster focusing in lower light, and its sensor-shift image stabilization helps retain sharpness handheld.

The Samsung DV300F has a longer 25-125mm zoom yet with a slower variable aperture (f/2.5-f/6.3), which impacts AF speed and low-light focusing. It also uses contrast-detection AF but with fewer reported focus points and somewhat less consistent tracking in my experience.

In practice, the Pentax AF felt snappier and more reliable, especially in tricky light or with moving subjects, thanks in part to its better lens aperture and sensor combo.

Neither supports continuous AF or phase detection, so neither is ideal for fast, professional sports photography. But if your action shots aren’t breakneck speed, the Pentax is the safer bet.

Suitability Across Photography Genres

How do these cameras hold up for different photography styles? Let’s examine each:

Portrait Photography

Pentax’s wider f/2 lens at 25mm and face detection AF help nail skin tones and focus on eyes consistently. Its sensor delivers cleaner images with less noise, making portraits pop even indoors or under weaker light.

Samsung’s longer zoom offers more reach but slower aperture and less refined AF, making smooth background blur (bokeh) and skin tone rendering less convincing.

→ Win: Pentax for portraits thanks to faster lens and superior AF.

Landscape Photography

Pentax’s better dynamic range and color accuracy deliver landscapes with more tonal depth and detail. Importantly, its weather sealing means you’re freer to shoot in rain or dusty environments.

Samsung can produce decent landscape files in good light but limited weather resistance and poorer dynamic range reduce its versatility.

→ Win: Pentax for rugged, outdoor landscapes.

Wildlife Photography

The Samsung’s longer zoom (up to 125mm equivalent) offers a slight edge in reach, but slow aperture hampers AF speed and low-light performance. Burst shooting is non-existent in both, so neither will capture fast moving critters perfectly.

Pentax, while shorter lens reach, has better AF responsiveness and stabilization to keep shots sharp.

→ Win: Slight edge to Pentax for balanced AF speed and image quality.

Sports Photography

Neither camera caters to pro sports, lacking high burst rates and fast AF. Pentax’s quicker shutter speed ceiling (up to 1/4000s) and better AF tracking make it better for casual sports snaps.

Samsung maxes out at 1/2000s shutter, limiting action freezing.

→ Win: Pentax for sports shooting.

Street Photography

Small size and discreteness matter here. Samsung shines with compactness and unobtrusive looks. Its lighter body lets you shoot casually without drawing attention.

Pentax, bulkier and more rugged, might scare off candid subjects but gives peace of mind against rough conditions.

→ Win: Samsung for stealth street shooting.

Macro Photography

Pentax’s 1cm macro focus is impressive, capturing tiny details up close. Its sensor shift IS helps with stability.

Samsung’s macro limit is 5cm, less versatile for extreme macro shots.

→ Win: Pentax for macro lovers.

Night and Astro Photography

Pentax's sensor performs better at high ISO (up to 6400 natively), with cleaner noise control supporting nighttime handheld shots. The longer shutter max (4 seconds) also helps capture star trails or low light scenes.

Samsung maxes out at ISO 3200 and shutter speeds max at 1/16th sec - more restrictive for night work.

→ Win: Pentax hands down for low light and astro.

Video Capabilities

Pentax shoots Full HD at 30fps and supports 720p at 60fps. Samsung is limited to 720p max with 30fps.

Neither supports external mics or headphone ports, and stabilizers differ:

• Pentax employs sensor-shift stabilization.
• Samsung uses optical image stabilization.

Pentax’s higher resolution video and better stabilization make for smoother results in handheld conditions.

→ Win: Pentax for video shooting purposes.

Travel Photography

Ergonomics, battery life, weather sealing, and versatility combine here. Pentax’s rugged build and 240-shot battery life mean fewer worries about damage or power mid-trip.

Samsung’s smaller size is a bonus for carry-on packing, but it lacks toughening and shorter battery life (unspecified but generally below Pentax).

→ Win: Pentax for adventure travelers, Samsung for light urban travelers.

Professional Use

Neither camera offers RAW support or extensive manual controls - important for pro workflows. Pentax’s superior sensor and image quality make it better backup compact for casual professional use, but for strict pro demands, neither is a primary tool.

Technical Tidbits and Connectivity

• Storage: Pentax uses standard SD/SDHC/SDXC; Samsung requires MicroSD. SD cards generally preferred for speed and capacity.

• Connectivity: Pentax has Eye-Fi compatibility and HDMI out, while Samsung offers basic built-in wireless but no HDMI.

• Battery Packs: Pentax uses D-LI92 (240 shots), Samsung BP88 with unspecified life.
