Leica C vs Pentax WG-3 GPS: A Hands-On Comparison for Photography Enthusiasts

When I first picked up the Leica C and the Pentax WG-3 GPS side by side, I couldn’t help but feel these two compact cameras come from totally different worlds - yet somehow live in the same category. Both are small-sensor compacts announced in 2013, but their design philosophies, target users, and feature sets couldn’t be more distinct. The Leica C is a stylish, travel-friendly compact with an emphasis on image quality and versatility, while the WG-3 GPS is a rugged, waterproof point-and-shoot made for adventure enthusiasts who want to shoot in harsh environments.

After spending several weeks evaluating each through various photography disciplines, I’m ready to break down how these cameras perform in real life, from portraits and landscapes to macro and video. I’ll also dive deep into the tech specs and usability, and - most importantly - help you decide where your hard-earned dollars might be best spent.

Getting a Feel for Size and Ergonomics

First impressions matter. The physical size and handling of a camera can make or break your shooting experience, especially if you like to keep things light and portable.

The Leica C is noticeably more compact and lighter at 195g compared to the Pentax WG-3 GPS's 238g. Measuring 103 x 63 x 28 mm, the Leica fits snugly into most jacket pockets and small bags. The Pentax is chunkier (125 x 64 x 33 mm), built tough for outdoor abuse, and that extra bulk is apparent in hand. It feels solid, but I wouldn’t call it pocket-friendly without a dedicated case.

In terms of grip comfort, the Leica’s sleek lines and modest protrusions mean it doesn’t offer much in the way of deep thumb rests or finger clubs - something you really notice if you’re used to DSLRs or larger mirrorless bodies. The controls are minimal but thoughtfully placed; it’s clearly designed for casual shooting with quick access to key settings.

The Pentax WG-3 GPS, being rugged and weather-sealed, has a more tactile grip with rubberized textures and oversized buttons that are easy to operate even with gloves - a major bonus if you intend to go hiking, snorkeling, or climbing. That said, the aggressive styling and bulk make it less suited for everyday casual use or travel when packing light is a priority.

Design and Control Layout: Function Meets Form

Beyond size, how a camera’s controls are laid out can hugely impact your ability to shoot efficiently - especially when the light is fading, or the action is fast-moving.

On the control front, Leica sticks to its minimalist ethos. The top plate features a simple mode dial with standard PASM modes plus some custom settings, and the shutter button rings with a zoom lever - classic Leica style. The buttons are flush but responsive, yet there’s no illuminated backlighting, which can hinder quick adjustments in dim conditions.

Pentax WG-3 GPS takes a different route. Instead of a mode dial, it relies on a more automated shooting experience with fewer manual controls. The top holds a power switch, shutter button, and a mode selector that includes its rugged capture options (like underwater modes and night scenes). The WG-3 GPS lacks an electronic viewfinder entirely, which might be a downside for some but keeps the top plate clean and straightforward. Buttons are large and raised, making them very tactile but possibly more prone to accidental presses in a crowded backpack.

If you’re someone who prefers direct control over aperture, shutter, and ISO, the Leica will serve you better. Pentax leans heavily on automation and durability, meaning fewer clubs for your thumbs but possibly fewer opportunities to “take the reins” in complex lighting.

Sensor and Image Quality: The Heart of the Matter

Here’s where technical specs meet practical results - the sensor size, resolution, and imaging pipeline define how your pictures will look.

The Leica C houses a 1/1.7" CMOS sensor measuring 7.44 x 5.58 mm with a 12MP resolution. The Pentax WG-3 GPS sports a slightly smaller 1/2.3" BSI-CMOS sensor at 6.17 x 4.55 mm but punches up the megapixels to 16MP.

In sensor technology, Leica’s 1/1.7" size grants it a slight edge on image quality over many compact cameras, especially in dynamic range and low-light performance. The BSI (backside illuminated) design in the Pentax sensor is optimized for better light gathering in a smaller chip, which partly offsets its size disadvantage.

Putting theory into practice, Leica’s images exhibit cleaner noise characteristics up to ISO 800, and better tonal gradation in shadows and highlights. The Pentax produces sharper images with higher resolution at base ISO but struggles a bit more beyond ISO 400, showing noticeable chroma noise. This is typical for the sensor size and pixel density combination.

The Leica’s 28-200mm equivalent lens is quite versatile for travel and everyday use, with a fast f/2 aperture at the wide end helping with portraits and shallow depth of field effects. Pentax’s 25-100mm f/2.0-4.9 lens covers less telephoto reach but offers a closer macro capability at just 1cm focusing distance.

For print-worthy landscapes or portraits where subtle skin tone rendition matters, the Leica C holds the advantage thanks to sensor size and lens aperture.

Viewing Experience and Interface Usability

When framing shots, composing images, and reviewing files, your experience is affected hugely by the viewfinder and rear LCD quality.

Leica C’s fixed 3-inch TFT LCD has 920k dots resolution, which translates to a crisp display with good color accuracy and brightness. It also includes a 200k pixel electronic viewfinder with a 0.46x magnification. The EVF coverage is 100%, which means what you see is exactly what you get at framing time.

The lack of touchscreen on Leica is a slight bummer given its 2013 vintage, but the physical buttons and use of joystick-like AF area selection allow precise manual focusing and navigation through menus without too much hunting.

By contrast, the Pentax WG-3 GPS offers a similar 3-inch screen but at a much lower resolution of 460k dots - visible in lower detail and less sharpness in bright daylight. There’s no electronic viewfinder, so you’re stuck composing only through the LCD, which can be tough in strong sun despite the anti-reflective coating.

Pentax’s menus are straightforward but limited, reflecting its place as a rugged point-and-shoot. The interface doesn’t support manual exposure modes - something landscape or portrait shooters will find restrictive.

Autofocus and Shooting Performance

For anyone shooting wildlife, sports, or street scenes, autofocus (AF) system speed and burst capabilities are key criteria.

The Leica C utilizes a contrast-detection AF system with face detection and continuous tracking. It doesn’t have phase-detection pixels, so AF speed is respectable but not razor-sharp in very low light or fast action. The AF sensor points are “unknown” in number, but the Leica’s multi-area AF and face detection work reliably in day-to-day shooting.

Continuous shooting tops out at a quick 10fps, which is excellent for a compact. This gives you some opportunity for burst shooting of fleeting moments or wildlife.

The Pentax WG-3 GPS has 9 AF points with contrast detection and face detection, but it lacks continuous AF or burst shooting modes. It shoots single images on demand only, which is a dealbreaker for sports shooters or anyone trying to capture rapid movement.

For static scenes, both cameras deliver accurate AF performance. For action or wildlife, the Leica’s tracking and faster burst rate trump Pentax’s more casual operation.

Ruggedness and Environmental Factors

One of Pentax WG-3 GPS’s big headlines is its legendary toughness. If you’re a serious outdoorsperson or travel in rough conditions, this can be a deciding factor.

The WG-3 GPS offers full waterproofing (up to around 40 feet), dustproofing, shockproofing from drops up to 1.5m, freezeproofing to -10°C, and crushproof resistance up to 100kgf. It also has built-in GPS tagging and electronic compass functionality.

Leica C has no weather sealing or rugged build and should be treated as a delicate compact - it’s not meant for rain-soaked hikes or beach days. For studio, street, and controlled travel, it’s fine. For adventure shooters, Pentax dominates.

Macro and Close-Up Photography

Both cameras boast macro capabilities, but there are noticeable differences in range and approach.

Pentax WG-3 GPS achieves a remarkable 1 cm minimum focus distance, great for insect or flower shots revealing intricate textures. Combined with sensor-shift stabilization, handheld close-ups get a boost on sharpness.

Leica C’s macro distance is 3 cm, deeper but still respectable. Its brighter wide aperture also helps produce a nicely defocused background (bokeh) for artistic macro compositions.

If your main interest is macro photography with lots of fieldwork and natural elements, the WG-3 GPS’s extended zoom and close focus ability make it the clear choice.

Low-Light and Night/Astro Performance

Shooting in low light or night scenes exposes a camera’s sensor and stabilization quality most tellingly.

Thanks to the Leica’s larger sensor, higher base ISO, and optical image stabilization, you get cleaner images and more usable shutter speeds handheld. The Leica maxes out native ISO 6400 and offers better noise control up to ISO 1600.

Pentax max ISO is similar at 6400 but the denser pixel array and smaller sensor size translate to noisier results in dark settings. The sensor-shift IS helps, but I found tripod use beneficial for astro or night photography with Pentax.

Neither camera offers built-in astro modes or very long exposures by default (max mechanical shutter speed is 60 seconds Leica, 4 seconds Pentax), so they are not tailored to serious nightscape work.

Video Capabilities and Audio

Videographers looking for 1080p capture have different experiences here.

Leica C records Full HD 1080p up to 60fps in MPEG-4 or AVCHD formats, with an external mic input port - a rare feature in compact cameras. This allows for improved sound recording when paired with a shotgun or lapel mic, making it decent for lightweight vlogging or run-and-gun video shooting.

Pentax WG-3 GPS also shoots 1080p but only at 30fps max. It records in MPEG-4 H.264, but lacks an external microphone port, and no headphone jack means no audio monitoring.

Neither camera offers 4K or advanced video features, but Leica’s external mic input and higher frame rate support will meet more demanding users’ needs in simple video workflow.

Battery Life and Connectivity

Leica C comes with a rechargeable battery pack rated for about 250 shots per charge. Pentax WG-3 GPS is similar at 240 shots. Both fall short for all-day shooting without spare batteries or external chargers, which could limit extended trips. Using power-saving modes and judicious LCD use helps maximize endurance.

Connectivity-wise, Leica supports built-in Wi-Fi and NFC, letting you quickly share images or remotely control the camera via smartphone apps. Pentax WG-3 GPS supports Eye-Fi wireless card integration for image transfer but lacks built-in Wi-Fi or Bluetooth. GPS is built into the Pentax, which Leica lacks.

For travelers and content creators needing rapid sharing, Leica’s wireless and NFC features are clear advantages.
