Pentax WG-10 vs Sony Cyber-shot H55: A Hands-On Comparison for the Practical Photographer

When hunting for a compact camera, you don’t just want specs on paper - you want real-world capability, reliability, and value. Today, I’m diving deep into a head-to-head comparison of two compact shooters that might seem like odd acquaintances at first glance: the Pentax WG-10 and Sony Cyber-shot DSC-H55. Both arrived to the party years ago (Pentax in mid-2013, Sony back in 2010), but each still has something to offer in very specific niches.

In this comparison, I’ll draw on years of hands-on experience with compact cameras, putting both through rigorous tests across photography genres - from portraits to landscapes, wildlife to street scenes, and even video work. We’ll explore how sensor tech, autofocus, ergonomics, and build quality impact your real shooting experience. And I’ll candidly reveal which camera suits different photographers, budgets, and purposes.

Let’s get started with a look under the hood and how these cameras feel in the hands.

Physical Feel and Design: Built for Rugged or Casual Use?

From the outset, the Pentax WG-10 stands out physically for its ruggedness. This camera isn’t just splash-proof; it’s waterproof, crushproof, shockproof, dustproof, and freezeproof. The solid build makes it a perfect companion for adventurers, hikers, beachgoers - anyone who might risk the camera in rough conditions. It’s compact yet chunky (116x59x29mm, just 167g), with grippy textured surfaces.

Contrast this with the Sony H55, which is more of a traditional compact. It’s slightly lighter (200g) and a bit smaller (103x58x29mm), but it lacks environmental sealing or any rugged credentials. It’s designed more for casual travel and everyday shooting, not for cannonballing into shallow streams. That said, the slightly slimmer dimensions make it easier to slip into smaller bags or coat pockets.

Look closely at the top controls:

The Pentax offers a minimalist control scheme - perfect if you want simple, no-fuss shooting - but the buttons are on the small side and can be fiddly with gloves. Sony’s more traditional layout is a little more refined, with better spread and dedicated dials for exposure compensation and zoom. I appreciated the Sony’s clubs for thumbs on extended outings, though I wish both had illuminated buttons for low-light handling.

Ergonomics takeaway: If you want a camera to survive harsh environments, WG-10. If you want something pocketable and easy to handle for casual shoots, Sony H55 fits better.

Sensor and Image Quality: Same Chip, Different Outcomes

Both cameras share a 1/2.3" CCD sensor measuring 6.17x4.55mm - standard fare for compacts in this range - and both have similar 14-megapixel native resolution. Technically, the Sony edges out slightly with a max image size of 4320x3240 vs Pentax’s 4288x3216, but the difference is academic, and won’t impact most prints or screen viewing.

However, the real difference emerges in ISO performance and dynamic range. The Pentax max ISO tops at 6400 with a native minimum of 125, whereas Sony’s max ISO is 3200 and goes as low as 80 natively. That gives the Pentax an advantage if you’re shooting in dim conditions, although CCD sensors aren’t stellar at high ISOs compared to more modern CMOS tech.

In practice, both deliver decent results with good color rendition and detail at base ISO. That said, I found the Sony’s Bionz processing engine does a better job controlling noise at mid-ISO levels (400-800), while the Pentax tends to get a bit grainier by ISO 800 and above. Additionally, the Pentax uses sensor-shift image stabilization, which helps in shaky shooting situations, while Sony employs optical stabilisation via the lens. Both are effective but the Sony’s optical system is marginally better in reducing blur in low light.

Image quality verdict:

• Landscape and daylight shooting: I’d lean slightly to Sony for cleaner mid-ISO output and more flexible zoom.
• Low light and underwater: Pentax has the edge due to higher ISO reach and rugged sealing.

Autofocus and Shooting Speed: Speed vs Precision

Autofocus is often a make-or-break feature for enthusiast photographers. Here, the two take notably different approaches.

The Pentax WG-10 uses contrast detection AF with 9 focus points and includes face detection, which works well enough in good light but can struggle tracking moving subjects. It also has “aftracking” features - though in practical use, I found it slow to reacquire focus when subjects moved quickly. Continuous autofocus is not supported.

The Sony H55 offers a 9-point contrast-detection AF with center-weighted priority and multi-area autofocus options. While it lacks face detection, the AF is noticeably faster and more reliable, especially in bright conditions. Burst shooting is much swifter on the Sony - 10 fps continuous vs a sluggish 0.7 fps for the Pentax. This makes the Sony a better pick for sports or wildlife photography where you want to capture split-second action.

Neither camera offers advanced AF options like phase detection or eye-tracking common in modern cameras, so neither is ideal for demanding fast action, but Sony’s speed is more useful overall.

Display and Interface: How You Control Your Shots

Both cameras use a fixed 2.7" to 3" LCD with about 230k dots resolution. The Pentax has a 2.7" widescreen TFT with anti-reflective coating, which performs reasonably well in sunlight. Sony's larger 3" screen is similar in clarity but not notably better.

Neither has touchscreens or electronic viewfinders, which limits precise framing or quick menu navigation, but the menus are straightforward and accessible. Pentax lacks illuminated buttons, so shooting in the dark can be a pain, whereas Sony’s backlit elements make it a little easier to tweak settings on the fly.

Pentax’s lack of an electronic viewfinder is not surprising given its rugged nature, but Sony missing this might disappoint street shooters who prefer discreet eye-level framing.

Zoom Range and Lens Capability: Versatility vs Simplicity

The lens focal ranges tell a compelling story of focus:

• Pentax WG-10: 28-140mm equivalent (5x zoom), aperture F3.5-5.5
• Sony H55: 25-250mm equivalent (10x zoom), aperture F3.5-5.5

Sony’s 10x zoom is a clear winner if you want reach - for example, wildlife or sports enthusiasts needing long telephoto range would favor the H55. The Pentax’s zoom maxes out at 140mm, wide enough for landscapes and casual telephoto but limiting for getting closer to distant subjects.

For macro photography, Pentax’s 1cm minimum focus distance is outstanding, allowing very tight close-ups. Sony’s minimum macro distance is 5cm, decent but less aggressive. So if you like bugs, flowers, or detailed texture photography, Pentax has the edge.

Durability and Weather Resistance: This Is Where the WG-10 Really Shines

It’s worth re-emphasizing: the Pentax WG-10 is a tough little camera built for extreme conditions. Waterproof to a few meters, shockproof from drops, and able to withstand freezing temps, it’s designed to handle harsh environments where others would cry uncle.

The Sony H55 has no weather sealing or shockproofing. A casual stroll in light rain or dusty streets might be tolerated, but anything more adventurous demands caution.

If your photography includes travel to rugged outdoor locations or you simply want a worry-free waterproof “point and shoot,” Pentax is clearly the champ here.

Video Capabilities: Not for Filmmakers, But Useful for Casual Clips

Both cameras only offer HD video at 1280x720 resolution max, with Pentax supporting 60 and 30 fps, Sony at 30 fps only. These are entry-level specs by today’s standards.

Neither models have microphone or headphone ports, or advanced video features like 4K recording, slow motion, or autofocus during video. The Pentax can do timelapse recording, a nice bonus.

Realistically, neither is a serious video shooter, just useful for occasional clips or quick documentation.

Battery Life and Storage: Staying Power and Flexible Media

The Pentax WG-10 uses a proprietary D-LI92 battery rated for about 260 shots per charge. The Sony H55 uses NP-BG1 batteries, also proprietary but with an unspecified official rating. Anecdotally, the Sony tends to run longer on a single charge - perhaps 300-350 shots - but this varies with use.

Both use single memory card slots - Pentax accepts SD/SDHC/SDXC and internal storage, while Sony supports a broader range including Memory Stick Duo formats commonly favored in older Sony models plus SD/SDHC.

Wireless Connectivity: Modest Offerings

Pentax’s Eye-Fi compatibility means you can use Eye-Fi cards for wireless image transfer, though this requires buying special cards and can be finicky. Sony H55 lacks any wireless connectivity (no Wi-Fi or Bluetooth).

This means that neither camera shines in instant social sharing or remote control functionality, a drawback for today’s content creators craving seamless connectivity.

Real-World Photography Tests: From Portraits to Night Skies

Over weeks of field testing, I assessed both cameras in diverse scenarios:

• Portraits: The Pentax’s face detection and contrast-based AF worked okay indoors in steady lighting, but struggled in low light. Its bokeh is average due to limited aperture. Sony’s faster AF and longer zoom helped capture casual portraits from a distance, but lack of facial recognition made sharp focus hit or miss when moving.

• Landscapes: Both delivered decent dynamic range considering sensor tech. Pentax’s weather sealing gave confidence shooting waterfalls and rainy trails. Sony’s wider zoom enabled tighter framing on distant peaks.

• Wildlife: Sony’s 10x zoom and faster burst rates favored shutter-happy captures of birds and critters. Pentax’s slow continuous shooting made it frustrating.

• Sports: Neither were professional sports shooters, but Sony’s higher frame rate made a difference in playground soccer snaps. Pentax’s slow speed was a dealbreaker here.

• Street Photography: Sony was more discreet and less bulky. Pentax's rugged design felt chunky and less stealthy. Both lacked EVF, which equals missed framing opportunities.

• Macro: Pentax dominated close-focus performance, capturing stunning detail at 1cm.

• Night/Astro: Limited by CCD sensor noise and basic ISO; neither shines, but Pentax’s higher ISO ceiling allowed marginally better low-light snaps.

• Video: Basic casual clips only. Pentax’s 60fps option is a slight plus.

• Travel: Pentax’s durability plus light weight make it a strong travel companion; Sony is easy to carry around but less reassuring in rough conditions.

Final Thoughts: Practical Wisdom from the Field

Comparing the Pentax WG-10 and Sony H55 is a lesson in niche specialization. The Pentax has bravado built into its frame - perfect for those who photograph in the wildest of conditions and prize durability more than speed. The Sony is more of a quick-response everyman’s compact, favoring versatility and speed in tame environments.

Both are older cameras; you won’t get the bells and whistles of today’s midrange compacts or mirrorless systems. Neither supports RAW, limiting post-processing control. But for casual photographers, budget buyers, or those needing simple waterproof flexibility, they present interesting, distinct options.

If your budget allows and you want more modern performance, I would generally suggest looking toward recent mirrorless or advanced compact models. However, if you pick up a Pentax WG-10 or Sony H55 secondhand for a modest price, now you know exactly how each will serve your photographic pursuits.
