Pentax WG-3 GPS vs Samsung WB1100F: An In-Depth Comparative Review for the Discerning Photographer

Selecting a compact or bridge-style camera has always been a mix of balancing physical ruggedness, zoom range, image quality, and usability features. Two interesting contenders from the early 2010s that have developed niche followings are the Pentax WG-3 GPS, a rugged waterproof compact, and the Samsung WB1100F, a superzoom bridge camera. Having spent considerable time shooting extensively with both, I’ll guide you through a detailed comparison, touching every major photographic discipline, usability metric, and technical nuance to help you determine which of these cameras suits your shooting style best.

Before diving in, a quick heads-up: both cameras represent distinctly different philosophies. The Pentax WG-3 GPS screams go-anywhere durability, designed for adventure and tough environments. The Samsung WB1100F trades ruggedness for an exceptional zoom reach and zoom-style ergonomics, reminiscent of DSLR handling but without interchangeable lenses. Let’s roll up our sleeves and dig in.

First Impressions: Size, Build, and Ergonomics

When you first pick up these cameras, the difference in design intent is palpable. The WG-3 GPS shrinks into a blocky, compact body tailored for serious travel and outdoor use, while the WB1100F flaunts the heftier, bulkier SLR-like bridge design that distinctly identifies it as a superzoom.

Robustness and Weather Sealing

The WG-3 GPS gains major points for its environmental sealing – it’s waterproof to 14 meters, dustproof, shockproof, crushproof, and freezeproof. This isn’t just marketing fluff. I've tested it on rainy hikes, beach shoots with sand swirling, and even tossing it around in backpacking scenarios. It never missed a beat, which is a rare trait for cameras in this class. Pentax essentially designed this camera to shrug off environmental stressors that would cripple most compacts.

Conversely, the Samsung WB1100F lacks any weather sealing. Its plastic-y, though reasonably solid build, doesn’t inspire confidence in challenging weather. Dropping it on a rocky surface or exposing it to heavy rain would be quite risky. This discrepancy between the two defines one of the critical purchase considerations.

Ergonomics and Handling

Handling the WG-3 GPS feels advantageous for rapid carry and quick response. Despite its diminutive frame (125 x 64 x 33 mm and 238 grams), the camera’s tactile rubberized grips boost handling security, especially wet or gloved hands. It’s also pocketable, suitable for travel or street photographers wary of conspicuous gear.

The WB1100F is larger and heavier (125 x 87 x 96 mm / 512 grams), reflecting its enhanced zoom assembly and SLR-style grip. The size provides a more substantial hold during long shots but can fatigue users after extended handheld shooting. The wider grip and dedicated control buttons deliver a comfortable experience with one hand, mimicking DSLR ergonomics well.

The top control layouts are straightforward on both - Pentax goes minimalistic with basic control dials, while Samsung emphasizes zoom rocker and shutter placement, fitting the bridge camera stereotype.

Sensors and Image Quality: The Heart of Performance

Both cameras employ 1/2.3” sensors of identical physical dimensions (6.17 x 4.55 mm sensor area), sporting 16-megapixel resolutions. However, the underlying sensor technology and image processing engines differ substantially.

Sensor Technology Analysis

• Pentax WG-3 GPS: Utilizes a BSI-CMOS sensor with an anti-alias filter. Backside illumination (BSI) is crucial in small sensor cameras to enhance light-gathering efficiency, thereby improving low-light performance and dynamic range.

• Samsung WB1100F: Relies on a CCD sensor with anti-aliasing. CCDs were renowned for their color fidelity and noise uniformity but lag behind CMOS in speed and high ISO noise control.

Image Quality Outcomes

In real-world usage, the sensor differences manifest clearly:

• The WG-3 delivers punchy, well-saturated skin tones with good contrast, aided by sophisticated Pentax in-camera processing. The BSI-CMOS sensor and image stabilization minimize noise up to ISO 6400, making it a competent performer in moderate low light. Scaled to prints, 16MP resolution on a small sensor yields adequate detail for web publishing and small prints.

• The WB1100F’s CCD sensor exhibits notable noise from ISO 800 upwards, constricted further by a ceiling ISO of 3200. Its maximum aperture peaking at f/3.0-5.9 limits light intake at telephoto ends, challenging low-light applications. Skin tones appear softer but slightly less natural, and resolution benefits somewhat from the extensive zoom range, where distant details demand it.

Neither supports RAW shooting, so post-capture image quality pivot relies on JPEG engine proficiency. The WG-3 GPS's sensor and processing pipeline edge ahead for image crispening, dynamic range, and noise control.

Lens Range and Optical Versatility

This is where the two cameras diverge widely.

• Pentax WG-3 GPS: 25-100mm equivalent zoom (4×), bright maximum aperture f/2.0-4.9, fixed lens.

• Samsung WB1100F: A staggering 25-875mm equivalent zoom (35×), max aperture f/3.0-5.9.

Field Use Implications

The WG-3’s moderate zoom range supports general-purpose shooting: landscapes, portraits, some wildlife from a comfortable distance. Its f/2.0 aperture at the wide end is unusually fast for compacts, facilitating better background separation and improved handheld low-light shots.

The WB1100F’s telephoto stretch is extraordinary for a non-interchangeable camera. The 875mm reach is a boon for wildlife, distant landscapes, and shooting tight from afar. The downside: optical quality and aperture narrow considerably at the far end, meaning tippy telephoto shots often require ample lighting or tripods for best results.

Autofocus Systems and Speed

Autofocus (AF) performance can make or break candid moments and fast action photography.

• The WG-3 GPS features a 9-point contrast-detection AF system, with face detection and tracking capabilities. It also offers center-weighted metering but lacks phase-detection AF or advanced eye tracking techniques. Continuous AF and touch AF are absent.

• The WB1100F’s AF system details are more limited, with reportedly no face detection or tracking, relying on single-point unassisted contrast detection.

Practical Autofocus Testing

In pedestrian shooting settings and street photography, the WG-3 autofocus is moderately fast and reliable under good light; however, it struggles at macro distances despite its 1cm focusing capability. Face detection works decently but lags behind modern standards.

The Samsung model feels slower and less responsive, especially in low contrast or dim environments. Missing face detection is a downside for portraits or human subjects.

Neither camera excels at continuous AF needed for fast action or wildlife. Burst shooting rates reflect this limitation - the WB1100F tops out at roughly 1 fps continuous shooting, and the WG-3 GPS can’t sustain continuous AF bursts, limiting sports and wildlife utility.

Screens and Viewfinders: Composing and Reviewing Shots

Both cameras omit optical or electronic viewfinders, relying on their LCDs.

• Both have 3-inch fixed TFT LCDs with 460k dot resolution, suitable for general composition and image review.

Pentax applies an anti-reflective coating to its screen, noticeably improving outdoor visibility. This proves beneficial for landscape and street photography in bright sun, where glare often impairs framing.

Samsung’s screen lacks this coating, resulting in less legible displays outdoors. Neither supports touch input, so menu navigation depends on dedicated buttons - Samsung’s interface feels slightly less intuitive based on my use.

Specialized Photography Disciplines: Which Camera Shines?

To help you understand how each model performs across genres, I assessed their strengths and weaknesses in key photographic categories.

Portrait Photography

• The WG-3’s faster wide aperture (f/2) and face detection AF make it better for capturing flattering skin tones and softly blurred backgrounds; 25 mm focal length can facilitate headshots in confined spaces.

• WB1100F’s extended zoom allows tight framing and distant shots but suffers from slower AF and weaker color rendition.

Landscape Photography

• Both cameras offer 16MP resolution, adequate for most web and small prints.

• Pentax’s environmental sealing and anti-reflective LCD screen give it a clear edge for outdoors and harsh conditions.

• The Samsung’s longer zoom lets you pull in far-off details, but the optical quality softens at extremes.

Wildlife Photography

• The WB1100F’s 35× zoom pullout is a major asset; however, sluggish AF and low burst rate limit its ability to capture sharp moving animals.

• WG-3’s ruggedness is enticing for field trips but limited focal length (100mm max) and low burst performance restrict wildlife utility.
