Pentax WG-3 vs Sony HX350

Pentax WG-3 vs. Sony HX350: A Thorough Face-Off Between Rugged Versatility and Superzoom Power

When it comes to choosing your next camera, the range of options can be dizzying - compact rugged shooters, bridge superzooms, mirrorless hybrids, and DSLRs all carve out different niches. Today, I’m focusing on a camera duo that speaks to two very different photography philosophies: the Pentax WG-3, a rugged waterproof compact built for adventures, and the Sony Cyber-shot HX350, a bridge-style superzoom powerhouse with a 50x reach. Both sport 1/2.3"-type BSI CMOS sensors and fixed lenses but differ dramatically in design, handling, and intended use.

Having spent several weeks with these cameras side-by-side - hiking muddy trails with the WG-3 and snapping distant wildlife with the HX350 - I’ll dissect their strengths, weaknesses, and core competencies. This comparison aims to help shooters decide which one fits their practical needs best - whether you crave durability and outright portability or sheer zoom power and flexible exposure controls.

Let’s dive into how these two cameras stack up across genres, performance, and usability.

Size and Handling: Compact Ruggedness vs. Bridge-Style Bulk

The difference in size and ergonomics between the Pentax WG-3 and Sony HX350 is as stark as their distinct user profiles.

Pentax’s WG-3 touts a hard-shell compact design that's truly pocket-friendly, measuring just 124x64x33 mm and weighing 230 g. It sports grippy rubberized body panels that feel like they can survive a tumble on a rocky trail or a quick dunk underwater with ease. This camera is built with a waterproof (up to 14m), shockproof, dustproof, freezeproof, and crushproof shell designed explicitly for outdoor use. It’s a genuine tough cookie for adventure photographers.

In contrast, the Sony HX350 is a hefty bridge camera, borrowing the SLR-ish form factor for better grip and control. It’s much larger at 130x93x103 mm and significantly heavier at 652 g - almost three times the WG-3’s heft. While it isn’t weather sealed or ruggedized like the Pentax, its heft affords a steady hold on its mammoth 50x zoom lens and a substantial grip for extended shooting sessions at length.

Looking at the top view reveals how these size differences translate into control layout and usability. The WG-3 keeps things simple with a handful of buttons and a well-placed mode dial, truly minimalist for quick operation in challenging conditions. Meanwhile, the HX350’s top plate offers more conventional DSLR-style controls - dedicated dials, zoom rocker, and additional buttons - lending it respectable manual control for enthusiasts.

Verdict: If you want an ultra-portable, take-anywhere camera that can withstand harsh treatment without worry, the WG-3 takes the crown. For a more conventional handling experience with an emphasis on lengthy zoom sessions and manual overrides, the HX350 is more ergonomic, despite its larger footprint.

Sensor Technology and Image Quality: Two 1/2.3" BSI CMOS Sensors But Different Resolutions

Both cameras house a 1/2.3" BSI CMOS sensor, a ubiquitous size in compact cameras, balancing cost and performance but limiting low-light and noise handling versus larger sensors.

The Pentax WG-3 features a 16MP sensor with an anti-aliasing filter designed to reduce moiré patterns. Its max native ISO tops out at 6400, with a base ISO of 125. The physical sensor area is about 28.07 mm² - typical for the segment.

Sony pushes pixel count higher with a 20MP sensor on the HX350, albeit with a slightly lower max native ISO of 3200 but supports ISO expandability up to 12800. That additional resolution gives the HX350 an edge in cropping or slightly larger prints but can bring increased noise at higher ISOs due to smaller photosites.

Real-world, the WG-3’s sensor delivers pleasant outdoor images with mostly punchy colors and reasonable dynamic range for its class. Its anti-reflective LCD coating helps a lot when shooting in bright sunlight. However, ISO performance beyond 1600 introduces noticeable noise, and the lack of RAW shooting limits post-processing flexibility.

Sony’s HX350 sensor, aided by the BIONZ X processor, produces sharper images with better detail retention and arguably more nuanced color reproduction. While ISO 3200 images get noisy, the chromatic noise remains manageable, especially when shooting at base ISO 80-400. However, the lack of RAW support on both cameras is a disappointment, limiting their appeal to advanced shooters who crave more editing latitude.

Verdict: Both cameras’ sensors have well-known limitations typical for 1/2.3" chips - but the Sony HX350 edges forward in resolution and color fidelity, better suited for those prioritizing detail at long telephoto focal lengths.

Autofocus and Speed: Pentax’s Contrast Detection vs. Sony’s Faster Hybrid

When testing autofocus (AF) systems, I aim to replicate real-world shooting scenarios: fast-moving children, wildlife, and in low-light conditions.

The WG-3 uses a contrast-detection AF system with 9 selectable points and an option for face detection. The system is reasonably quick for a compact but can struggle in dimmer environments or tracking erratic subjects. However, its 10 fps continuous shooting mode is commendable in its category, useful for snapping bursts during active moments on hikes.

The HX350 also relies on contrast detection but benefits from the more advanced BIONZ X processor enabling more responsive autofocus with better accuracy. It offers continuous AF during burst shooting up to 10 fps and selectable AF points including center and multi-area modes - making it more versatile for dynamic subjects.

Neither camera sports phase detection AF or advanced tracking capabilities, so neither is ideal for high-speed sports. The HX350’s larger form factor and longer lens give it an operational advantage when tracking distant subjects, but both are ultimately limited by sensor size and budget constraints.

Verdict: The Sony offers a better experience for autofocus speed and accuracy, especially for moving subjects. The Pentax works well for casual snaps but is less reliable when action heats up.

Build Quality and Environmental Durability: Pentax’s Fortress vs. Sony’s Delicate Powerhouse

Pentax’s WG-3 shines unmistakably in physical durability. It’s built like a tank with full environmental-sealing guarantees: waterproof to 14 meters, shockproof to 1.5 meters, freezeproof down to -10°C, dustproof, and crushproof to 100 kgf. This makes it a trusted companion for adventure travel, scuba diving, hiking in challenging weather, or mountain biking. Its ruggedness can be a deal breaker if you want reliability under harsh conditions without carrying extra protecting gear.

In contrast, the Sony HX350 is a standard bridge camera with no weather sealing or rugged features. It’s more susceptible to dust, moisture, and shock - not something to risk bringing on extreme adventures unless extra protective housing is used.

Verdict: The Pentax WG-3 is the clear choice for users needing a tough, go-anywhere camera that won’t quit. The Sony is best for more controlled conditions like casual outdoor shoots or travel photography where careful handling is possible.

Screen and Viewfinder: Where Viewing Meets Control

Both cameras feature a 3-inch LCD but differ markedly in resolution and flexibility.

Pentax includes a fixed, anti-reflective 3-inch TFT LCD with 460k-dot resolution. This screen is straightforward, reliable, and effective under sunlight thanks to the coating, although the lower resolution means less crisp live image feedback.

Sony ups the ante with a 3-inch tilting screen boasting 922k dots - providing clear, bright framing and easier shooting from low or high angles - a feature sorely missed on the WG-3.

Sony complements this with a 202k-dot electronic viewfinder (EVF) covering 100% of the frame, which is a massive plus for composition in bright sunlight or when holding the camera steady on long zooms.

Pentax leaves out the viewfinder completely, relying solely on the rear LCD.

Verdict: The HX350 delivers a versatile, bright viewing experience with EVF and tilting screen. The WG-3’s screen is simpler but adequate for its rugged mission, though the lack of a viewfinder might frustrate some users outdoors.

Lens Versatility: Wide to Moderate Zoom vs. Monster Telephoto Reach

Here’s where these cameras really differentiate themselves.

Pentax WG-3 sports a 4x optical zoom lens covering 25-100 mm equivalent with a bright aperture range of f/2.0-4.9. The fast f/2.0 wide end is excellent for low light and creative depth of field control, especially useful for close-ups and environmental portraits. Its macro focusing can get as close as 1 cm, making it handy for detail shots without extra gear.

Sony HX350 cranks it up with a 50x optical zoom lens ranging an astonishing 24-1200 mm equivalent, though aperture narrows from f/2.8 at wide-angle to f/6.3 at full telephoto. This focal reach puts faraway wildlife, sports, or distant landmarks well within frame. Although aperture isn’t as bright at the telephoto end, optical image stabilization assists to reduce blur at long focal lengths.

Neither lens is interchangeable, but Sony's massive zoom breadth offers far more compositional flexibility, while Pentax opts for rugged simplicity over reach.

Verdict: Pick the Pentax WG-3 for wide-angle versatility and macro prowess in challenging environments. The HX350 is your superzoom go-to, ideal for subjects out of arm’s reach.

Video Performance: Modest but Functional

Both shoot Full HD 1080p video, but with some nuances:

• Pentax WG-3 records 1080p at 30 fps or 720p at 60 fps using MPEG-4 and H.264 codecs. It lacks a microphone input, which restrains serious video work, but does have timelapse recording and decent stabilization via sensor-shift.

• Sony HX350 offers 1080p 60i or 50i depending on region (interlaced 60/50 fps), plus AVCHD and MPEG-4 formats. It also lacks mic/headphone ports, limiting audio control. Stabilization is optical, helping telephoto handhold shots.

Neither is a video powerhouse, but both handle casual video assignments well. Neither offers 4K or advanced cinematic features like zebras or log profiles.

Verdict: Video is a secondary function on both, with Sony’s higher resolution screen and smoother 1080p options edging ahead.

Battery Life and Connectivity: Lean and Functional

The WG-3 gets about 240 shots per charge from its D-LI92 battery, a bit on the lower side but typical for compact rugged cams with powerful onboard electronics. It supports Eye-Fi wireless card connection for limited wireless functions but no Bluetooth or NFC.

Sony HX350 boasts a longer battery life of ~300 shots, a welcome bonus during long daylight outings. It has no wireless connectivity onboard, limiting remote control or file transfer ease.

Both cameras use single SD card slots, with Sony additionally accepting Memory Stick Pro Duo cards - a convenience for shooters transitioning from older Sony gear.

Verdict: Sony’s HX350 slightly leads in battery endurance. Connectivity-wise, the WG-3’s Eye-Fi support can be useful but limited by current Wi-Fi standards.
