Pentax WG-10 vs Sony NEX-5T: An Expert Camera Comparison from Field Tests to Studio Insights

Choosing between the Pentax WG-10 and Sony NEX-5T presents a fascinating study in contrasts: a rugged waterproof compact aimed at adventure junkies versus a more refined entry-level mirrorless designed for versatility and image quality. Having spent significant hands-on time with both cameras, testing them across multiple photography disciplines, I’m eager to unpack their technical nuances, real-world performance, and ultimately, who they serve best.

I’ll dive deep into their build, sensor architecture, autofocus behaviors, lens ecosystems, usability, and output quality to provide a nuanced, informed perspective. Since both models debuted in 2013, it will also be interesting to see how their respective design philosophies fare today. So grab your favorite lens and join me on this journey through waterproof compact design and mirrorless sophistication.

Size, Handling, and Ergonomics: Compact Toughness vs Mirrorless Versatility

One of the first impressions any photographer gauges when picking up a camera is the physical feel and control layout. The Pentax WG-10 is a pocketable, rugged compact camera clearly engineered with adventure photographers in mind. Its dimensions measure a mere 116x59x29 mm with a featherweight 167 g. In contrast, the Sony NEX-5T, a mirrorless rangefinder-style system camera, clocks in larger and heavier at 111x59x39 mm and 276 g. This difference stems largely from the interchangeable lens mount and larger sensor architecture.

The WG-10's small footprint and contoured grips provide a firm hold even when wearing gloves - useful for hiking, diving, or winter shoots. The buttons are straightforward, with simple exposure controls tailored for ease of use rather than granular manual tweaking. Weather sealing and shockproof claims give peace of mind that this camera won’t balk at wet or rough conditions.

Conversely, the NEX-5T's grip offers more refinement, suitable for extended handling and complex compositions. Its rangefinder styling with a tilting screen fosters more flexible shooting angles, ideal for portraits or street photography. However, it’s not weather sealed, and with the added bulk of lenses, isn’t quite the grab-and-go companion the WG-10 is.

Sensor and Image Quality: Tiny CCD vs APS-C CMOS Saga

Critically, the core of any camera’s imaging prowess lies in its sensor. The Pentax WG-10 opts for a 1/2.3-inch CCD sensor measuring 6.17x4.55 mm with a 14-megapixel resolution. Its image area totals just 28.07 mm² - relatively minuscule, even by compact camera standards. The CCD sensor helps with color reproduction but struggles with noise above ISO 640, which is also its maximum native ISO. The DSLR and mirrorless realms have mostly migrated to CMOS sensors, which offer more dynamic range and low-light capabilities.

Meanwhile, the Sony NEX-5T houses a significantly larger APS-C sized CMOS sensor at 23.4x15.6 mm and 16 megapixels. This jump to 365.04 mm² sensor area marks a huge advantage in image quality potential, from sharper detail to superior low-light handling and dynamic range.

From my side-by-side pixel peeping and studio tests, the Sony outperforms the Pentax handily in color depth (23.6 bits vs unknown for the WG-10), dynamic range (about 13 stops vs unknown), and noise resilience. Even in well-lit outdoor scenes, the WG-10’s smaller sensor output lacks the fine tonal gradients and sharpness achievable with the NEX-5T.

For photographers focused on quality, the larger sensor combined with Sony’s Bionz processor is the clear winner, unlocking possibilities like shooting in RAW (supported on Sony, not Pentax) and extensive post-processing latitude.

Autofocus and Shooting Speeds: Tracking the Moment

When it comes to capturing fast-moving subjects or fleeting expressions, autofocus speed and accuracy can make or break an experience. The Pentax WG-10 offers a basic contrast-detection autofocus system with 9 focus points and face detection. The contrast-detect method demands more time to lock focus, and continuous autofocus or tracking modes are absent, leading to occasional missed focus in action scenarios.

In contrast, the Sony NEX-5T employs a hybrid AF system combining contrast and phase detection with 99 focus points and 25 cross-type sensors. This setup excels in quick, precise focusing, including continuous AF, tracking AF for moving subjects, and selective AF point assignment.

Its burst shooting clocks in at 10 frames per second compared to the WG-10’s sluggish 0.7 fps, making Sony far more capable for wildlife, sports, or street photographers chasing decisive moments.

Display and Viewfinder: Comfort and Composition

Live view information and monitor quality significantly affect framing and focusing ease. The WG-10’s 2.7-inch fixed-type 230k-dot LCD offers basic functionality with anti-reflective coating. It's serviceable in bright conditions but limited in resolution and no touch capabilities.

Meanwhile, the NEX-5T shines with a 3-inch tilting touchscreen at 922k resolution, tilting up 180° for selfies (very selfie-friendly) and down 50° for low-angle compositions. Touch autofocus and intuitive menu navigation add to user friendliness.

Neither has a built-in electronic viewfinder, but Sony supports an optional EVF - helpful for bright light shooting and precise manual focusing. The Pentax lacks a viewfinder altogether.

Lens Ecosystem: Fixed Lens Convenience vs Expansive Choice

The Pentax WG-10’s lens is fixed, spanning 28-140 mm 35mm equivalent at a modest aperture of F3.5-5.5, and boasting a close macro focus distance of 1 cm. This versatility supports everyday travel and macro shots near water with the rugged build intact. However, the lack of interchangeable lenses means you’re stuck with the optical limitations inherent to the fixed zoom.

Sony’s E-mount offers access to over 120 native lenses from Sony and third-party manufacturers, including primes, zooms, and specialty optics. This opens the door for portraits, landscapes, sports, or macro with appropriate fast apertures and focal lengths.

Again, this points to the WG-10 as a dedicated point-and-shoot for adventure conditions, and the NEX-5T for those valuing creative lens flexibility.

Build, Weather Sealing, and Durability

The Pentax WG-10 is a champion waterproof, shockproof, freezeproof, crushproof compact designed to handle the elements. With environmental sealing and protections against dust, water (immersion up to 10 meters), shocks from 1.5-meter drops, and freezing temperatures down to -10°C, it is a workhorse for outdoor or action scenarios.

Contrarily, the Sony NEX-5T has no official weather sealing, demanding more cautious handling in adverse environments. Its metal/chassis construction offers durability for casual shooting but is unsuited for rugged adventure.

This clear design divergence must guide your decision depending on shooting location and conditions.

Battery Life and Storage Options: Ready for the Day or Cruise Control?

Battery life favors the Sony NEX-5T with around 330 shots per charge versus the Pentax WG-10’s approximate 260 shots. The larger capacity aligns with the power demands of the bigger sensor and advanced features but remains average versus modern models.

Storage-wise, both accept SD cards, but the NEX-5T also supports Sony’s proprietary Memory Stick Pro Duo series for versatility.

Connectivity and Extras: Wireless, Timelapse, and Video

The WG-10 supports Eye-Fi wireless card connectivity but has no Bluetooth or NFC. Its video capability tops out at 720p HD at 60fps - basic by today’s standards but ahead of many compacts in 2013.

Sony’s NEX-5T includes built-in Wi-Fi plus NFC for rapid pairing and image transfer to smartphones - a significant advantage for social and travel photographers. Video recording reaches 1080p Full HD at 60 fps, with AVCHD and MPEG-4 support. Although lacking microphone or headphone jacks, it delivers respectable video quality.

Timelapse is native on WG-10, making it a fun tool for long exposures or documentary-style subjects out in the field. The NEX-5T lacks built-in timelapse but users can manage this through external apps or manual shooting.

Real-World Performance Across Photography Disciplines

Portrait Photography

The Sony NEX-5T’s larger APS-C sensor naturally renders smoother skin tones and better tonal gradations. Its support for interchangeable fast prime lenses means you can achieve creamy bokeh and precise eye detection autofocus - crucial for impactful portraits.

Pentax WG-10’s fixed lens offers limited aperture range and modest autofocus without face or eye priority mode, yielding less flattering skin textures and background separation. Still, it handles casual snapshots outdoors quite well.

Landscape Photography

The 16MP APS-C sensor on Sony provides ~1 stop more dynamic range than compact sensor peers, revealing greater shadow detail and highlight retention ideal for landscapes. Raw shooting enables extensive editing.

Pentax’s sensor struggles in dynamic range, especially under challenging light. Its weather sealing gives an edge in wet or dusty environments, but image quality is a compromise.

Wildlife and Sports Photography

Burst speed, autofocus tracking, and telephoto options put the Sony NEX-5T far ahead. Its 10fps continuous drive and 99 AF points plus lens interchangeability allow tracking fast subjects with excellent precision.

Pentax, with 0.7fps burst and slower AF, suits only static wildlife or casual use.

Street Photography

Pentax’s small size and discreet fixed lens makes it a stealthy street shooter in bustling scenes. Good weather resistance means less worry about exposures in unexpected weather.

Sony’s NEX-5T is bulkier but offers silent electronic shutter modes (though limited/no silent shutter on this model), better low-light autofocus, and tilting screen goodness for difficult angles and selfies.

Macro Photography

The Pentax WG-10’s 1cm macro focus range and sensor-shift stabilization make it surprisingly capable up close, especially outdoors.

Sony’s E-mount allows dedicated macro lenses with superior optics, but no built-in stabilization. Macro enthusiasts will appreciate lens choices but lose some convenience compared to Pentax’s fixed macro zoom.

Night / Astro Photography

With a maximum native ISO of 6400, Pentax hits a noise wall quickly, limiting astro potential to short exposures in extremely dark locales. The NEX-5T maxes out at native ISO 25600 and features excellent low-light noise handling, enabling longer exposures and cleaner starscapes.

Video Capabilities

Sony leads here with Full HD 1080p at 60fps, multiple codecs, and touch operation. Lack of mic jacks crimp professional audio, but handheld stabilization and lens options permit quality filmmaking.

Pentax’s 720p limit and basic codec are fine for casual clips but no match for serious video.

Travel Photography

For travelers wary of bulk or rough conditions, WG-10’s waterproof, shockproof body and compact size makes it a trusty companion. However, image quality and low-light performance are secondary.

Sony offers striking image quality and creative control in a still-compact form, but adds care needed around water or dust.

Professional Workflow Integration

Sony’s support for RAW, extensive lens compatibility, and manual exposure controls cater well to professional workflows for portrait, event, or studio shooters. Pentax lacks RAW and advanced exposure modes, limiting professional use.

Pricing and Value: Budget-Savvy or Invested Creativity?

As of launch, the Pentax WG-10’s price point was ultra-affordable (around $100 or less), designed for customers prioritizing durability and simplicity over image quality. The Sony NEX-5T set buyers back approximately $400 body-only - more of a serious stepping stone into interchangeable lens systems.

Today, with NEX-5T units still retrievable used, they offer great value for enthusiasts seeking quality APS-C entry without breaking the bank, whereas the WG-10 holds appeal for niche users needing ruggedness.
