Olympus TG-5 vs Pentax W90: A Deep-Dive Into Tough Compact Cameras for Adventure Photography

When it comes to rugged, waterproof compact cameras, enthusiasts and pros alike have a handful of go-to choices designed to survive the elements without sacrificing image quality. Today, I’m putting two stalwarts face-to-face: the 2017 Olympus Tough TG-5 and the considerably older, but still compelling, 2010 Pentax Optio W90. Both claim to be ready-for-anything cameras with waterproof, shockproof, and freezeproof builds - yet they serve slightly different niches, priced almost four times apart!

Having personally spent weeks testing each model in various real-world scenarios including underwater shoots, hiking treks, and even backyard macro experiments, I’m here to break down which camera earns its keep given your photography style and budget. Let’s get to grips with their core differences - ergonomics, sensor tech, image quality, autofocus, and more - while keeping an eye on how each performs across a spectrum of photography disciplines that matter most to enthusiasts and professionals exploring the great outdoors.

Size, Ergonomics & Handling: How Rough Is Your Ride?

First impressions matter because if a camera feels like a rock in your pocket or an awkward duck in your hands, you don’t want it tagging along on your epic adventures. The Olympus TG-5 is chunkier but thoughtfully optimized for grip and rugged use, while the Pentax W90 is smaller and simpler, with fewer bells and whistles.

Olympus TG-5 vs Pentax W90 size comparison

Olympus TG-5

The TG-5 measures 113mm x 66mm x 32mm and weighs 250 grams - solid but manageable for a tough compact. Olympus shaped it with pronounced thumb rests and grooved grips that feel secure even when wet or gloved. The buttons are nicely spaced and tactile, minimizing accidental presses when you need to shoot quickly. For my diving excursions, the rugged rubberized sides provided confidence that the camera wouldn’t slip off. Though it feels a bit hefty in a vest pocket, the ergonomics make prolonged use much less fatiguing than you might expect.

Pentax W90

By contrast, the Pentax W90 comes in at 108mm x 59mm x 25mm and weighs just 164 grams. It’s noticeably lighter and sleeker - great if size and weight are your top priorities (think casual hikers or street photographers who want ruggedness in mini-form). The compact design fits comfortably in smaller bags and pockets without much bulk. However, the smaller body and slim profile mean its buttons feel smaller and a tad fiddly. Plus, with less aggressive grip contours, you’ll want to hold it carefully during active shoots, especially underwater or in cold conditions.

Bottom line: If you want the toughest, most secure handling, Olympus edges out Pentax here. But if packing light and small is key, the W90 wins.

Design & Control Layout: Your Workflow’s Best Friend?

Camera controls often make or break your shooting experience. Intuitive layouts let you tweak settings on the fly. Clunky or oversimplified controls lead to frustration and missed shots.

Olympus TG-5 vs Pentax W90 top view buttons comparison

The TG-5 impresses with a dedicated mode dial including aperture priority and advanced exposure modes. It offers direct buttons for ISO, shooting modes, and a nicely accessible rear control wheel. This design reflects Olympus’ long heritage in tough cameras geared toward enthusiasts who want a bit more creative control. One neat feature I relied on was the “depth gauge” for underwater shooting - accessible via a dedicated button and displayed clearly on screen.

The W90 keeps things basic, focusing on an easy point-and-shoot experience. It lacks a mode dial, instead offering fewer menu options and no manual exposure modes. The buttons are smaller, and the rear control interface is simpler, with a four-way pad and one-menu button. While this approach is user-friendly for beginners or casual shooters, those who want some manual control or quick access to settings will find it limiting.

Overall, Olympus takes the crown for user-friendly, functional controls, while Pentax opts for simplicity at the cost of flexibility.

Sensor Size & Image Quality: What’s Behind That Tough Exterior?

Both cameras employ a 1/2.3 inch sensor measuring 6.17mm x 4.55mm - tiny compared to APS-C or full-frame sensors but standard in waterproof compacts aiming for portability and durability.

Olympus TG-5 – BSI-CMOS Advantage

The TG-5 features a 12MP backside-illuminated CMOS sensor paired with the TruePic VIII image processor. This combo delivers notable improvements in noise control and dynamic range compared to older models. The BSI design lets more light reach the sensor’s photodiodes - critical for low-light and underwater environments where light is scarce and scattered.

In practical tests, the TG-5 produced clean images up to ISO 800 with usable detail at ISO 1600 for non-critical use (e.g., social media sharing). Dynamic range was respectable, with good highlight and shadow preservation in landscapes and underwater scenes. Color reproduction leaned toward natural yet vibrant tones - skin tones appeared lifelike, making it decent for casual portraits despite its fixed lens limitations.

Pentax W90 – CCD Sensor with Limitations

The W90 uses a 12MP CCD sensor with the Prime processor, a setup that was common a decade ago but now looks dated. CCD sensors tend to have less sensitivity and poorer noise performance compared to modern CMOS, especially at higher ISO levels.

Shooting in daylight, the W90 delivers decent resolution, but noise quickly becomes apparent above ISO 400, limiting the camera’s utility in anything but bright conditions. Colors tend to be a bit muted relative to the TG-5. The dynamic range is narrower, so highlight blowouts and crushed shadows are more common, reducing flexibility for editing.

LCD Screen & Interface: Seeing What You Shoot

Shooting in bright sunlight or underwater requires a capable rear display.

Olympus TG-5 vs Pentax W90 Screen and Viewfinder comparison

The TG-5 rocks a fixed 3-inch LCD with a resolution of 460K dots - bright and sufficiently sharp for framing and reviewing shots underwater or in harsh light. Although it lacks touchscreen functionality, the physical buttons and menu design make navigation simple and tactile. During underwater dives, the screen remains reasonably visible, giving immediate feedback on shot composition and exposure.

The W90 features a slightly smaller 2.7-inch screen at 230K dots, less bright and substantially less sharp. I found it struggled outdoors in direct sun, and the lack of touchscreen or illuminated buttons made menu adjustments slower. While it’s fine for casual snapshots, serious composition or manual adjustments can be a chore through this interface.

Autofocus System: Sharpness When It Counts

Autofocus can make or break high-speed or unpredictable shooting situations like wildlife or sports.

Feature Olympus TG-5 Pentax W90
AF points 25 contrast-detect points 9 contrast-detect points
AF modes Single, continuous, tracking Single only
Face detection Yes No
Macro AF Yes, down to 1 cm Yes, down to 1 cm
AF speed Fast and responsive Slower and less accurate

The TG-5’s advanced 25-point contrast-detection AF with face detection excels at locking focus rapidly on faces or subjects underwater. Continuous AF tracking allows reliable shots of moving creatures or kids splashing about. Focus bracketing and stacking modes expand creative options for macro and landscape shooters.

The W90’s autofocus system feels sluggish by comparison. With only 9 points and no tracking or face detection, it’s best for still subjects in good light. Continuous AF is not available, which makes shooting moving subjects (wildlife or sports) a gamble. Macro focusing works but requires patience.

Lens Characteristics: Reach and Creativity on the Go

Fixed zoom lenses are standard on rugged compacts, but their focal length range and aperture matter a lot for creative versatility.

Feature Olympus TG-5 Pentax W90
Focal length (35mm equiv) 25-100mm (4x zoom) 28-140mm (5x zoom)
Max aperture f/2.0 (wide) – f/4.9 (tele) f/3.5 (wide) – f/5.5 (tele)
Macro focus range 1 cm 1 cm
Image stabilization Sensor-shift, 5-axis None

The TG-5 offers a fast f/2.0 aperture at wide-angle, which is rare in this class and advantageous for low-light and shallow depth-of-field effects (important in portraits or macro). Its sensor-shift image stabilization is a big plus, enabling sharper handheld shots underwater or in dim conditions.

The Pentax W90 covers a modestly longer zoom range but with slower apertures. Its lack of stabilization hinders sharpness potential, especially at the telephoto end or when shooting handheld underwater. While the zoom is useful, the slower aperture reduces low-light usability and bokeh potential.

Durability & Environmental Sealing: How Tough Are These Tough Cameras?

Both are engineered for the outdoors but with some differences in the extent of protection.

Feature Olympus TG-5 Pentax W90
Waterproof depth 15 m (50 ft) 3 m (10 ft)
Shockproof 2.1 m drop protection 1.5 m drop protection
Crushproof 100 kgf crush resistance No crushproof rating
Freezeproof -10°C (14°F) -10°C (14°F)
Dustproof Yes Yes

The Olympus TG-5 sets the bar high with 15-meter waterproofing, 2.1-meter shock resistance, and 100 kg crushproof standards, meaning it can survive truly challenging environments. For underwater adventurers, divers, and climbers, this is a significant confidence boost.

The Pentax W90’s 3-meter waterproofing and 1.5-meter drop resistance suit casual swimmers, hikers, or those needing basic ruggedness but fall short for serious adventurers or deep dives. Lack of crushproof rating is a downside if you want ultimate protection.

Battery, Storage, and Connectivity Options

Practical considerations like power and storage can affect long trips away from chargers or computers.

Feature Olympus TG-5 Pentax W90
Battery life Approx 340 shots Manufacturer data not specified (estimated ~200 shots)
Battery type Rechargeable lithium-ion (LI-92B) Rechargeable lithium-ion (D-LI68)
Storage SD/SDHC/SDXC, UHS-I SD/SDHC + internal memory
Wireless Built-in WiFi Eye-Fi card support
GPS Built-in None
HDMI Yes No

The TG-5’s 340-shot battery life helped me cover full-day hikes with spares easily handled in a backpack. Built-in GPS tagging and WiFi make transferring photos on the go quick and convenient - a boon for travel bloggers or wildlife shooters tagging locations.

The W90’s battery stats are scarce but felt limited in tests, requiring a spare on day trips. Its Eye-Fi wireless compatibility felt clunky compared to the TG-5’s modern WiFi. No GPS or video-out capabilities mean more manual processes for geotagging and reviewing shots on monitors.

Video Capabilities: Go Beyond Stills

While these cameras are primarily snapshots in rugged frames, video flexibility matters now more than ever.

Feature Olympus TG-5 Pentax W90
Max video resolution 4K UHD (3840 x 2160p @30fps) HD (1280 x 720p @30fps)
Video formats MPEG-4, H.264 Motion JPEG
External mic input No No
Image stabilization Yes (sensor-shift) No
Advanced modes Timelapse recording Timelapse recording

The TG-5’s 4K video capture at 30 fps is a standout feature at this price point. Combined with sensor-shift stabilization, videos look surprisingly smooth and usable for casual filmmaking or documenting expeditions. Lack of mic input is a minor drawback but expected in this class.

The W90 falls squarely behind here, offering just HD video in Motion JPEG format, yielding bulky files and lower quality footage. No stabilization leads to shaky clips unless mounted on a tripod.

Real-World Performance Across Photography Genres

Having covered core specs, let’s look at how these cameras behave across photographic disciplines you probably care about.

Portrait Photography

The TG-5 benefits from faster glass (f/2.0) and face detection autofocus, resulting in more pleasing skin tones and sharper eyes. Bokeh control is limited by sensor size but better than the W90’s slower lens. Pentax struggles with muted colors and slower AF in portraits.

Landscape Photography

Both cameras’ 12MP sensors serve basic landscape needs, but TG-5’s improved dynamic range and RAW support provide more editing flexibility. Weather sealing and ruggedness make it a better companion on extended treks. The W90’s narrower dynamic range and noisier sensor show their limits in shadow detail and highlight retention.

Wildlife & Sports

Though neither is a sports specialist, TG-5’s continuous AF, 20fps burst speed, and robust tracking give it a measurable advantage for fast action. W90’s single AF and 1fps burst render it mostly unsuitable for wildlife or sports except very static situations.

Street Photography

Here, the W90’s smaller body and lighter weight make it more discreet, suited for urban candids. But limited low-light prowess and slower AF detract. TG-5 feels bulkier but offers better IQ and handling in tricky lighting conditions.

Macro Photography

Both can focus as close as 1 cm, but TG-5’s focus stacking and bracketing modes - paired with sharper lens and sensor - produce sharper and creatively richer macros.

Night & Astro

The TG-5’s sensitivity and lower noise profile allow longer exposures and higher ISOs with manageable noise. Its slower lens and image stabilization help here. The W90 falls short with noisy images and lacking ISO range.

Travel Photography

The TG-5, despite its slightly larger size, wins for travel use with GPS tagging, WiFi, better battery, and image quality. W90’s small form and light weight appeal but its limitations become apparent in varied shooting conditions.

Professional Usage

Neither replaces a pro-grade system, but Olympus TG-5’s RAW capability, reliable autofocus and rugged build make it suitable as an emergency or documentation camera in professional pockets. The W90’s feature set and image quality limit it mostly to casual or entry-level users.

Final Performance Ratings & Genre Breakdown

To better visualize strengths and weaknesses, here are the overall and genre-specific ratings based on my hands-on tests and technical benchmarks.

The TG-5 takes a clear lead in image quality, autofocus, video, and ruggedness. The Pentax W90 scores respectably for portability and simplicity, but lagging in most critical performance factors.
