Pentax WG-90 Blue Review: a tough little camera for the pool, beach and jobsite

I picked up the Pentax WG-90 Blue mainly because I was tired of babying my phone every time I went to the pool or out in the rain. I wanted something I could toss in a backpack, use with wet hands, and not panic if it dropped on concrete. After a couple of weekends at the pool, a rainy hike, and a bit of messing around in the sink and bathtub (yes, very scientific testing), I’ve got a decent idea of what this thing is good at and where it feels a bit dated.

The first thing to know: this is not a mirrorless camera replacement. It’s more like a beefed-up point‑and‑shoot that doesn’t care about sand, water or cold. It’s waterproof to 14 meters and rated to survive a 1.6m drop and -10°C. In practice that means it’s perfectly fine for snorkeling, the beach, the lake, or a construction site. I didn’t dive to 14m, but it handled being submerged, splashed, and banged around in a bag without any issues or leaks.

Image quality is decent for a 1/2.3" 16 MP sensor. If you’re used to a recent smartphone, you’re not going to be blown away, but you also get shots that a phone simply can’t take because a phone would die in the same conditions. That’s kind of the whole point of this camera: not to beat your phone in perfect daylight, but to keep working where your phone won’t.

Overall, my first impression is: very practical tool, slightly old-school experience. Menus feel a bit like a camera from a few years ago, the screen resolution is nothing special, and it leans heavily on automatic modes. But if your priority is a tough camera for water, mud and rough handling, it already feels like it earns its place in the bag.

Value is where opinions will split. If you just want better image quality than your phone, this is not the right purchase. A decent mid-range phone will match or beat the WG-90 in many normal situations. But that’s not really the point. The WG-90 makes sense if you specifically need something rugged, waterproof and replaceable. For example: parents who don’t want to risk a €800 phone at the pool, people who work on construction sites and need photo documentation, or anyone who spends a lot of time around water and rocks.

Compared to other rugged compacts (from Olympus/OM System or older WG models), the WG-90 sits in the standard mid-price zone. It doesn’t try to compete with high-end 1-inch sensor compacts, and it doesn’t have fancy features like 4K, RAW capture, or wireless connectivity. What you’re paying for is a known formula: 16 MP sensor, 5x zoom, 1080p video, and a rugged shell that can take a beating. If you can find it on discount, it starts to look like good value for a dedicated beater camera.

If you already have a rugged phone case and a waterproof pouch, you might feel this is redundant. Personally, I like the peace of mind of having a separate device that I don’t care about dropping in salt water or mud. Also, the Digital Microscope and macro lights are not something most phones can copy easily, especially at 1 cm distance. That said, if you’re more into image quality and creative control than durability, your money is better spent on a different camera or simply upgrading your phone.

So, in short: the WG-90 is good value for people who actually need ruggedness and underwater use, and only average value for everyone else. If you’re not going to dunk it, drop it, or take it into rough conditions, you’re paying for features you won’t really use.

Design-wise, the WG-90 Blue looks like something between a tool and a toy. It’s not sleek, it’s not minimalist, and honestly I’m fine with that. The front has that typical WG series “armored” look, with screws and textured surfaces, plus the six small LEDs around the lens. The blue color is bright enough that you don’t lose it easily in a bag or on the ground, which is actually useful near water or on a messy jobsite.

It weighs around 490 grams, so it’s not feather-light for a compact, but it still fits in a jacket pocket or a small pouch. In the hand, it feels solid but very plasticky. If you’re used to metal-bodied cameras or premium phones, this will feel cheaper, but that plastic is also part of what lets it take knocks without denting. I dropped it once from about waist height onto tile (not on purpose) and it just got a tiny scuff on a corner, no functional damage.

The buttons are all physical, with decent travel and clear marks. No touchscreen. On the plus side, you can use it with wet fingers or thin gloves. On the downside, the interface feels slower than tapping a screen, and scrolling through menus with arrows is a bit 2010. The shutter button is easy to find by feel, which matters when you’re underwater with goggles on and not looking closely at the camera.

The battery and card compartment has a proper locking door with a double action latch, which gives some confidence about the waterproofing. I made a habit of checking the seal for dust or hair before going in the water, and it never leaked. Ports are limited: you get USB and micro HDMI behind sealed covers, and that’s about it. No external mic, no hot shoe, no fancy accessories. The design message is pretty clear: this is a self-contained, rugged camera that focuses more on surviving rough use than on looking premium.

The battery situation is pretty standard compact-camera stuff. Pentax doesn’t shout the exact CIPA number in the marketing, but in practice I got around 200–250 shots plus a few short videos on a charge when shooting mostly in daylight with some menu browsing. On a pool day with a mix of underwater shots and 1080p clips, the battery icon dropped faster, and I ended up in the red by late afternoon.

The good thing is that the battery is removable, so you can just buy a second one and swap it. For something meant for travel, hiking and job sites, that’s important. I’d honestly call a spare battery mandatory if you plan on filming a lot of video or spending a full day snorkeling and reviewing your shots on the screen. Once you start checking photos often and running the macro LEDs, you feel the drain.

Charging is done via USB, plugging directly into the camera. It works, but it’s not the fastest, and you’re stuck with the camera tethered while it charges. I personally would have preferred an external charger in the box, especially for a device aimed at outdoor use where you might want to charge multiple batteries in rotation. As it is, you’ll probably end up charging overnight or using a power bank on the go.

One small plus: the camera handles cold reasonably well. I used it briefly in around 0–2°C weather, and the battery didn’t tank instantly like some phones do. Of course, capacity still drops in the cold, but at least it remains usable. Overall, I’d rate battery life as acceptable but not generous. It’s enough for casual users, but heavier shooters should budget for at least one extra battery.

This is the part where the WG-90 actually shines: it’s built to take abuse. Over my usage, I didn’t baby it at all. I tossed it in a beach bag with sunscreen and keys, used it with wet, sandy hands, and even let a kid handle it in the pool (under supervision). No issues with water ingress, no fogging inside the lens, and all the doors and seals still feel tight. The 14m waterproof rating is far more than what most casual users will ever hit; snorkeling and shallow dives are totally within its comfort zone.

The shockproof rating is 1.6m, which basically covers normal drops from hand height. I had one real accidental drop onto tile and a few intentional bumps on concrete just to see if it would scratch badly. It picked up some cosmetic marks, but functionally it was fine. The plastic body shows scuffs, but that’s kind of the point: this is more of a tool than a display object. If you’re used to treating your phone like glass, this thing feels liberating.

I also tried it briefly in cold conditions just above freezing, and the buttons and screen remained usable. The freeze-proof to -10°C claim seems realistic for occasional use, though I didn’t stand outside for hours testing it. For skiing, winter hikes or job sites in winter, it should cope better than a lot of phones that throttle or shut down from the cold.

Over time, the only thing you really need to watch is the rubber seals on the battery and port doors. A single hair or grain of sand can compromise the waterproofing if you’re unlucky. I got into the habit of giving the seals a quick visual check and a wipe before dunking the camera. As long as you do that, it feels like a pretty solid, reliable beater camera that can handle conditions where you’d never risk a normal compact or your main phone.

In terms of image quality, the WG-90 is fine as long as you keep your expectations realistic. In good daylight, photos are sharp enough, colors are slightly punchy but not cartoonish, and 16 MP gives you enough resolution for normal prints or social media. Compared to my mid-range smartphone, detail is roughly in the same ballpark, but the phone still wins on dynamic range and low-light noise. Where the WG-90 pulls ahead is in situations where your phone either can’t go (underwater) or where you don’t want to risk it (dusty or muddy sites).

The autofocus is simple: single-servo AF with contrast detection and basically one AF point. This is not a tracking monster. For static subjects or slow movement, it’s fine. For kids jumping in a pool or fast sports, you’ll get a mix of sharp and slightly soft shots. Shutter response is okay, but not ultra snappy. Burst shooting is up to 30 fps on paper, but that’s more about short, low-resolution bursts or special modes; for normal full-res shooting it doesn’t feel that fast.

Low light is where the camera shows its age. The ISO goes up to 6400, but past ISO 800 you clearly see noise and smudging from noise reduction. Indoors in the evening, images are usable for memories, but they’re not pretty if you zoom in. The built-in flash helps, but it has the usual compact camera look: flat light and harsh shadows if you’re too close. The digital image stabilization is better than nothing but doesn’t replace optical stabilization. You can feel it especially for video and at the telephoto end of the zoom.

Video is limited to 1080p (Full HD) using MPEG-4/H.264. Quality is okay for casual clips, work documentation, or simple YouTube uploads, but again, it feels behind modern phones that do 4K with better stabilization and HDR. Autofocus during video sometimes hunts a bit, especially underwater or in low contrast scenes. For what it is – a tough compact – I’d describe performance as: gets the job done, no more, no less.

On paper, the Pentax WG-90 is a compact camera with a 16 MP back‑illuminated CMOS sensor, a 5x optical zoom (28–140mm equivalent), and Full HD 1080p video. Nothing crazy in 2026, but the twist is the rugged body: waterproof to 14m for up to two hours, shockproof from 1.6m, and freeze-proof to -10°C. It’s clearly built for casual underwater use, hiking, skiing, and jobsite photos rather than Instagram-perfect city shots.

The camera leans heavily on scene modes. You get specific settings for underwater stills and video, macro, sports, night portrait, landscape, panorama and so on. There’s also an Aperture Priority mode, but this is not a camera for full manual nerding. It’s more “point, choose the right scene icon, shoot”. The lens opens to around f/1.8 at the wide end (on paper at least), but with the small sensor you still get a lot of depth of field, so don’t expect blurry backgrounds like a big camera.

One of the standout features is the Digital Microscope mode with six built-in LED lights around the lens and an included macro stand. This lets you get as close as 1 cm from your subject and still keep things steady. In practice, I used it to shoot screws, plant leaves, and textures on rocks. It’s a bit of a gimmick on day one, but it’s actually handy if you work on a site, repair stuff, or just like close-up detail shots.

Overall, the feature set feels like a mix: the rugged part is up to date, the imaging specs are mid-range, and the user interface is slightly old school. If you’re expecting Wi‑Fi, Bluetooth, or smartphone-style touch controls, you’ll be disappointed. If you mainly want a tough compact camera that shoots JPEGs and 1080p video without drama, it checks the right boxes.
