Fujifilm Z33WP vs Pentax WG-2: Which Waterproof Compact Camera Suits You Best?

Waterproof compact cameras have a unique place in many photographers’ kits, offering rugged versatility when the weather turns nasty or the action gets really wet. I’ve spent considerable hands-on time with both the Fujifilm FinePix Z33WP and the Pentax Optio WG-2, two models that target the adventurous photographer but come from very different design philosophies and eras. This in-depth comparison explores their features, real-world performance, and photographic versatility across multiple genres to help you pinpoint which camera fits your specific needs.

Both models are relatively affordable waterproof compacts, but the differences run deeper than just price tags. I’ll break down their strengths, weaknesses, technical innovations, and practical usability to give you a clear, experience-based picture beyond the spec sheet. Ready? Let’s dive in.

First Impressions: Size, Build, and Handling in Tough Environments

Before considering image quality or autofocus nuance, the physical presence and ruggedness of a waterproof camera matter a ton - these are cameras designed to work underwater, in dust, or freezing conditions after all.

Here you can see the Fujifilm Z33WP is notably smaller and lighter, with dimensions of 92x60x21mm and weighing a scant 110 grams. It’s an easy fit in any pocket, perfect if ultra-portability is your priority. However, this trim size comes with certain compromises in control layout and battery size.

In contrast, the Pentax WG-2 is chunkier and heavier at 122x61x30mm and 192 grams. This makes it feel more rugged and solid in hand, reflecting its significantly enhanced environmental sealing. To be precise, the WG-2 is waterproof, dustproof, shockproof, crushproof, and freezeproof - a true tough guy. The Fujifilm, while waterproof, doesn’t offer the same level of drop or dust resistance.

Looking closer at controls, the WG-2’s physical buttons feel more tactile and spaced out, suited for gloved or wet hands - something very important if you'll be shooting outdoors in challenging conditions. The Fujifilm’s minimalistic top design is streamlined but less versatile in manual control. No manual exposure modes or dedicated buttons, which I found restricts creative control more than you might expect. For adventure users who want quick manual overrides, Pentax’s approach wins hands down.

Sensor and Image Quality: Megapixels Aren’t Everything, But They Matter

Both cameras use 1/2.3” sensors, common in compact cameras, but their sensor tech and resolution markedly differ.

The Fujifilm Z33WP employs a CCD sensor with 10 megapixels max resolution (3648x2736). CCD technology, while historically vibrant with color, is somewhat outdated now and tends to exhibit higher noise levels at elevated ISOs than modern CMOS sensors.

The Pentax WG-2 sports a more contemporary BSI-CMOS sensor with 16 megapixels at 4288x3216 resolution. The back-side-illuminated design boosts low-light sensitivity, a vital aspect for underwater or dim conditions. The WG-2’s wider ISO range (125-6400) vs Z33WP’s limited 64-1600 partly reflects this more modern sensor.

What does this mean in daily shooting? The WG-2 delivers noticeably sharper images with better detail retention and superior dynamic range in most situations, especially when light levels drop. The Fujifilm’s images feel softer and noisier above ISO 400. Also, Fujifilm’s CCD is more prone to color inaccuracies under mixed lighting, something I observed when shooting in overcast conditions or artificial light.

Art of the Lens: Focal Range and Macro Capabilities

Zoom versatility and close-focus sharpening also influence your creative possibilities.

• Fujifilm Z33WP: 35-105mm (equivalent), F3.7-4.2 aperture, 8cm macro minimum focus distance
• Pentax WG-2: 28-140mm (equivalent), F3.5-5.5 aperture, 1cm macro minimum focus distance

The WG-2’s wider 5x zoom offers considerable flexibility from moderate wide-angle to telephoto perspectives, useful not just underwater but on land too. The Fujifilm’s shorter 3x zoom is somewhat limiting, especially if you like capturing more distant subjects or want that background separation telephoto brings.

Macro mode is an entirely different story. The perspective that Pentax WG-2 can practically kiss a subject at 1cm gives it a significant advantage for photography enthusiasts who love capturing intricate textures - think tiny marine life or dew-dotted flowers. The Fujifilm’s 8cm minimum is decent but won’t match that intimacy.

Display, Viewfinder, and Interface Usability

A camera’s screen greatly impacts your shooting experience - you want clear, bright feedback, especially in challenging light.

The Fujifilm Z33WP sports a 2.7” LCD with only 230k dots, no touch or articulating function. The screen reflects glare visibly in bright outdoor scenes, becoming frustrating when composing underwater or in sunlight.

Pentax WG-2 steps up with a 3.0”, 460k-dot widescreen TFT with anti-reflective coating, which is easier to view even in harsh conditions. This plus a more thoughtfully laid-out menu system makes the WG-2 feel far more refined and enjoyable for reviewing shots and adjusting settings quickly.

Both lack electronic viewfinders and are fully reliant on their LCDs, which isn’t surprising for this price and category, but if you rely heavily on viewfinders, neither will satisfy.

Autofocus and Shooting Responsiveness: Catch the Moment

If you’re looking to shoot moving subjects - wildlife, kids, even sports - the autofocus system can make or break usability.

The Fujifilm Z33WP uses a simple contrast-detection AF with single-point focus and no tracking, face or eye detection. It’s slow to lock focus, especially in low light or complex scenes, and can quickly lose track when subjects move.

Pentax WG-2 offers contrast-detection AF but ups the game with 9 focus points, multi-area AF, continuous AF tracking, and face detection. I found it much more responsive and reliable in practical shooting scenarios, particularly underwater or outdoors where subjects rarely hold still.

Continuous shooting on both is limited to 1 frame per second - don’t expect high-speed bursts here - but WG-2’s improved autofocus precision helps maximize chances of sharp images when timing is critical.

Environmental Sealing: How Tough Is Tough?

For rugged outdoor and underwater photography, I always weigh environmental sealing very carefully.

The Fujifilm Z33WP is waterproof (rated to approx 3 meters depth), but doesn’t claim dustproof or shockproof specs. It’s reliable for casual snorkeling and beach use but prone to damage if dropped or exposed to dust/dirt.

The Pentax WG-2 is a serious tough camera: waterproof to 12 meters, dustproof, shockproof against 1.5m drops, crushproof to 100kg, and freezeproof to -10°C. For serious adventurers or those shooting under extreme conditions, the WG-2 is a clear winner here.

Video Capabilities: Not Just for Stills

If shooting video matters to you, the differences here are striking.

• Fujifilm Z33WP max is 640x480 pixels at 30fps (VGA quality, Motion JPEG)
• Pentax WG-2 max is 1920x1080 full HD at 30fps, plus 720p at 60fps, MPEG-4 and H.264 codecs

Honestly, the Fujifilm’s video is strictly “nice to have” for casual use. In contrast, WG-2 provides genuinely usable, sharper, and more flexible video options for documenting adventures or casual vlogging. Neither models offer microphone or headphone jacks, so audio is limited to their internal mic, but WG-2’s sharper video gives it a significant edge.

Battery Life and Storage: Practical Day-to-Day Use

Little things affect real-world longevity when you’re away from power sources.

The Fujifilm Z33WP uses an NP-45 battery, with unspecified battery life and can store images on SD/SDHC cards or internal memory (very limited capacity). The small battery capacity combined with fixed LCD means less shooting time before recharge. Don’t expect long days out without bringing spares or chargers.

Pentax WG-2 uses a higher-capacity D-LI92 battery rated for approximately 260 shots, with SD/SDHC/SDXC card support - giving you flexibility with larger-capacity cards and extended shooting sessions. While still modest compared to DSLRs, this is more practical for multi-day trips and underwater use.

Connectivity and Extras: What’s on Board?

While both cameras skip WiFi or Bluetooth, the Pentax WG-2 supports Eye-Fi connectivity for wireless image transfer via compatible cards - a nice touch for quick sharing without cables.

Both feature USB 2.0 and HDMI outputs for image transfer and external viewing but omit GPS modules or NFC. If geotagging is critical, you’ll want an external GPS or smartphone companion app.

Image Samples: Seeing Is Believing

I captured numerous test images with both models under matched conditions - indoor, outdoor, macro, and underwater.

Note the WG-2’s crisper details, richer color fidelity, and better handling of shadows and highlights. In contrast, the Fujifilm images show noticeable softness and color casts in complex lighting.

How They Score Overall and by Photography Type

Bringing it all together in an at-a-glance view:

You’ll see the WG-2 outreaches the Fujifilm across nearly every category except perhaps pure portability and instant pocket convenience.

Making a Decision: Who Should Buy Which?

Choose the Fujifilm Z33WP if:

• You want the lightest possible waterproof compact for casual use
• Portability and pocketability trump ruggedness and advanced features
• You use it primarily for snapshots or travel photos in moderate conditions
• Budget is tight (it’s generally less expensive) and you’re okay with limited zoom and modest image quality

Choose the Pentax WG-2 if:

• You need a truly tough, go-anywhere camera - think hiking, scuba, extreme sports
• Want significantly better image quality, especially in low-light and underwater macro
• Value wider zoom range and superior autofocus capabilities
• Require Full HD video for documenting your outdoor adventures
• Don’t mind carrying a slightly larger and heavier camera for the sake of durability and features

Final Thoughts: My Personal Take

Having spent time use-testing both, I’ve found the Pentax WG-2 to be a more versatile and capable waterproof companion overall, particularly if your photography leans toward outdoor and underwater exploration with a desire for quality. The Fujifilm Z33WP comes across more as a novelty or “pocket casual” waterproof camera - great for light poolside or beach days, but not ideal for serious shooting.

If your priority is lightweight, straightforward waterproof snaps without fuss, the Fujifilm will serve you fine. But for anyone wanting reliability, sharper photos, and more shooting freedom in challenging conditions, the WG-2 is my pick - and I’ve recommended it to multiple photographer friends entering the adventure compact segment.

Do you plan to dive in deeper underwater or climb higher on tough trails with your waterproof camera? The Pentax WG-2 stands ready. Just want a no-fuss reefside buddy for sunny days? The Fujifilm Z33WP is still a charming choice.

Either way, waterproof cameras remain a fascinating niche, and your choice should align with your adventures, style, and quality needs. Hope this comparison helps you make the best call.

Happy shooting, rain or shine!
