In the ever-evolving landscape of compact cameras, Pentax has carved a niche by melding usability with solid imaging performance - often with a twist, such as ruggedness or specialized features. Today, we dissect two noteworthy models from Pentax’s portfolio that, despite sharing a heritage, target distinct user types and shooting scenarios: the Pentax Optio H90 and the Pentax WG-3 GPS. These cameras are separated by three years in release date (2010 vs 2013) and by intended purpose, but how do they compare on the real-world front? What compromises have been made, what innovations stood the test of time, and more importantly, which camera still deserves consideration in 2024?

Drawing on hours of hands-on testing, sometimes with side-by-side shoots, and backed by a rigorous technical evaluation framework, I aim to deliver a thorough, candid comparison engineered around your needs. Whether you crave a versatile travel companion, a rugged outdoor shooter, or an everyday snapshot device with solid image quality, this comparison will guide your decision.

Let’s start by sizing them up - literally and figuratively.

First Impressions: Feel and Form Factor That's More Than Skin Deep

Many photographers underestimate just how much ergonomics and physical handling shape shooting enjoyment and control reliability. After extensive in-the-field use, it’s clear each model’s body design signals different priorities.

The Pentax H90 sports a compact shape traditional for point-and-shoot cameras of its era - small, lightweight (153g), and pocket friendly (101x65x28mm). Its grip is minimal but balanced, geared towards casual use. While I appreciate the easy portability, longer sessions left me craving more substantial feedback from the body, especially in challenging outdoor conditions.

Contrast that with the WG-3 GPS, which is chunkier and deliberately ruggedized, weighing 238g with dimensions at 125x64x33mm. The robust build incorporates waterproofing, dustproofing, shockproofing, and freezeproofing - elements not just for show. This camera demands your attention via tactile buttons and a generous handgrip, perfect for active users shooting in environments that punish fragile gear. It’s less about blending into crowds and more about withstanding the wild.

If pocket-scale travel and discretion top your list, H90 holds an edge. But if you want unflinching reliability in rough conditions without adding a big DSLR backpack, the WG-3 GPS is a winner ergonomically.

Design and Control Layout – Which One Puts You in the Driver’s Seat?

Beyond weight and size, control layout profoundly impacts shooting efficiency, particularly for photographers who value fast adjustments.

On the H90, controls lean towards simplicity - a typical three-way zoom rocker, a mode dial with limited exposure modes (no shutter or aperture priority), and a few buttons for straightforward menus. There is no physical AF-ON or quick access buttons, which can frustrate experienced shooters accustomed to reflexive control over autofocus or white balance. The LCD screen is fixed type and modest in resolution (230k dots) - enough for framing but limited for precision.

The WG-3 GPS introduces a more camera-like layout, despite its compact size. The buttons are larger, spaced nicely, and the zoom lever is responsive with a wide focal range. While it still lacks advanced manual exposure modes, there is face detection autofocus (absent in the H90), which you’ll appreciate when outdoors photographing family or wildlife. I felt more in command while quickly toggling between shooting and playback modes, helped by a bigger and sharper LCD (3.0-inch, 460k dots).

This camera also adds a dedicated record button for video, plus navigation directional controls mapped intuitively. If you crave tactile control without complexity, the WG-3 GPS layout feels purpose-built.

Sensor and Image Quality: Pixels and Physics in Play

Both cameras house a 1/2.3” sensor, a standard for compacts, but the story gets richer with sensor technologies, resolutions, and noise profiles.

The Pentax H90 sports a 12MP CCD sensor. CCDs yield pleasing color rendering and low noise at base ISOs but tend to struggle at higher ISOs and with dynamic range. True to form, the H90 delivers sharp 4000×3000 pixel images, with decent tonal gradations in good light. However, its limitation starts around ISO 400 where noise and softness creep in noticeably, shrinking your usable range. The non-existent RAW support is a disappointment for enthusiasts wanting post-processing latitude.

The WG-3 GPS, by contrast, pairs a 16MP BSI CMOS sensor. Backside-illuminated CMOS sensors offer improved low-light sensitivity and faster readout speeds, translating to more detail retention and better dynamic range across ISO settings. During tests, the WG-3 GPS was cleaner and crisper even at ISOs up to 800, with minimal chroma noise at higher settings. Despite lacking RAW output, JPEGs exhibited better latitude under challenging lighting - ideal for travel and outdoor photography where lighting changes rapidly.

From resolution alone, WG-3 GPS’s 4608×3456 pixel output naturally allows larger prints and more cropping potential. In texture-rich landscape or macro shots, this advantage is unmistakable.

Shooting Experience: Autofocus, Burst, and Stabilization

How these cameras transition from pointing to capture tells you a lot about their practical usability - especially when it comes to speed and reliability.

The H90 features 9 contrast-detection AF points and contrast-detection autofocus without face or tracking detection. Focus speed is leisurely by modern standards (approx. 1-2 seconds typical), which can frustrate when shooting moving subjects or fleeting moments. Burst mode maxes out at a single frame per second - suitable for casual shooting but insufficient for sports or wildlife.

Conversely, the WG-3 GPS has the same 9-point AF array but augments it with face detection autofocus, which greatly improves hit rates in portrait or street photography scenarios. While still lacking continuous burst autofocus, it performed modestly better in locking focus quickly under bright or moderately low light. Frustratingly, burst data is not specified, but practical experience shows it’s not designed for high-frame-rate shooting.

Both cameras rely on sensor-shift image stabilization - an invaluable feature given the limited apertures. In my trials, stabilization on the WG-3 GPS felt a bit more capable, though neither is a match for modern in-lens stabilization systems seen in mirrorless or DSLRs.

LCD and Viewfinder: Composing Your Shot

Neither camera offers an electronic viewfinder, which will be a deal-breaker for some photographers who prefer eye-level framing. Instead, each has an LCD with different traits.

The H90 uses a 2.7-inch screen with a very basic 230k-dot resolution, no touchscreen functionality, and limited brightness adjustment. Under sunny outdoor conditions, the screen’s visibility deteriorated quickly. I often resorted to shading with my hand, which is cumbersome.

The WG-3 GPS improves this with a 3-inch 460k-dot widescreen TFT LCD featuring anti-reflective coating that helps visibility outdoors. Though it lacks touchscreen input, the screen size and quality greatly enhance usability, particularly when shooting landscapes or video. Menu navigation and focus point confirmation are noticeably easier on this display.

In summary, the improved LCD technology of the WG-3 GPS is a tangible upgrade for compositional confidence.
