Canon PowerShot D20 vs. Pentax Optio WG-2 GPS: A Splashy Showdown of Rugged Compacts

When it comes to waterproof, rugged cameras, the market has always been a bit of a niche playground. These cameras cater to adventurers, travelers, snorkelers, and anyone prone to dropping their gear into perilous situations. In this comparison, I roll up my sleeves to pit two stalwarts from around the early 2010s - the Canon PowerShot D20 and the Pentax Optio WG-2 GPS - head-to-head. Despite their similar rugged DNA and price point hovering around $299, these compact toughies offer striking contrasts in specs, usability, and photographic performance.

Having tested thousands of cameras in a myriad of harsh and tame environments, I offer you not just a spec sheet regurgitation but real-world insights grounded in hands-on usage and deep technical scrutiny. Let’s dive in and splash down to discover which waterproof warrior deserves a spot in your kit.

First Impressions and Handling: Size, Shape, and Build

Tough cameras live and die by their ergonomics and resilient design, right? So, the initial feel - weight, grip, control layout - plays a huge role, especially when you’re fumbling in wet gloves or underwater.

The Canon D20 tips the scale at 228 grams and measures 112 x 71 x 28 mm, making it a slightly chunkier but still pocket-capable compact. Its heft feels reassuring - like it can absorb some abuse without folding. The Canon feels very solid in hand, with rubberized grip areas that enhance security when wet.

The Pentax WG-2 GPS, marginally lighter at 198 grams, goes a bit slimmer but trades some grip bulk for a slightly narrower profile (122x61x30 mm). In my experience, the slimmer, more streamlined chassis fits tighter pockets or adventure vests but at a cost of a bit less tactile assurance when wet or slippery.

Both cameras are engineered to be dustproof, waterproof, shockproof, and freezeproof - a commendable engineering feat for devices in this segment. Notably, Pentax tossed in crushproof capability, a nice extra insurance for rough-and-tumble scenarios like rock climbing or motorcycling.

Ergonomically, neither injects extravagance. Both forgo any electronic viewfinder (unheard of in compact rugged cameras), relying solely on their LCD screens. They lack touchscreen control, and physical buttons dominate the interface, which is surprisingly effective for nav in rugged contexts.

For visual orientation, this peek at control layouts from the top reveals subtle differences:

The Canon’s button layout is a bit more spaced out and filleted for ergonomics, with clear shutter and zoom rocker placement. Pentax keeps things minimalist, with accessible buttons but tighter spacing that might require some practice gloves on.

Sensor and Image Quality: Crunching the Numbers and Pixels

Now, let’s talk the tiny heart inside these compacts - their sensors. Both opt for a 1/2.3-inch size, which in our world of mirrorless and DSLRs is tiny - but par for the affordable rugged course.

Canon D20 employs a 12-megapixel CMOS sensor, matched with the venerable Digic 4 image processor. Given the age and sensor size, don’t expect dazzling resolution or superb low light prowess - but 12 MP offers sufficient detail for casual prints and social sharing.

In comparison, the Pentax WG-2 GPS pumps up resolution to 16 megapixels on a BSI-CMOS sensor, which is back-illuminated and generally heralded for improved light gathering in compact sensors. The ISO range extends higher to 6400 (versus Canon’s max ISO 3200), promising a sliver more flexibility in dim conditions.

From my tests, Pentax does deliver slightly sharper images with more detail retention - though it also shows a bit more noise at higher ISOs than Canon’s cleaner but softer output. Canon’s Digic 4 processor does a decent job balancing noise reduction and detail retention at its native ISO range.

The anti-aliasing filter on both cameras prevents moiré but slightly softens micro details - an understandable tradeoff on such tiny sensors.

Viewing and Interface: What You See Is What You Shoot?

Their LCD screens are both fixed 3-inch panels, but with subtle technological differences:

Canon’s PureColor II TFT LCD with a 461k-dot resolution offers good daylight visibility but can struggle under harsh direct sunlight - a paint point when shooting at the beach or bright snowy peaks.

Pentax’s screen boasts similar pixel resolution (460k dots) but dresses it in a widescreen TFT LCD with anti-reflective coating, which noticeably aids outdoor visibility. In rugged shooting environments, screen clarity and glitch-free responsiveness become crucial, and here Pentax nudges ahead.

Neither camera features touchscreen controls or displays an electronic viewfinder, so precise framing in bright water-split environments can be tricky and requires practice.

The interface usability is aimed at quick operation over fiddly setups. Both cameras lack all the semi-pro exposure modes like aperture priority or shutter priority - an obvious limitation for enthusiasts wanting creative control.

Autofocus Performance and Speed: Nailing the Shot on the Move

Autofocus can make or break your fast-paced outdoor shooting, especially in wildlife, sports, and underwater contexts. Both cameras rely on contrast-detection AF.

Canon’s D20 offers 9 focus points with face detection, and crucially supports continuous autofocus - handy for tracking moving subjects underwater or while hiking.

Pentax WG-2 GPS also boasts 9 AF points but lacks continuous AF - a notable handicap in dynamic scenes. It compensates somewhat by offering AF tracking, but in practice, the lack of continuous AF dampens responsiveness.

Both cameras allow manual focus – an essential tool for macro shots or tricky underwater autofocus situations where contrast can confuse the system.

In real-life snapping, Canon felt a tick faster and more consistent at locking focus on moving subjects, especially close-range macro or portrait eye detection (the latter gains in reliability with Canon’s face detection). Pentax’s autofocus occasionally hunts or dithers, which is a mild frustration when seconds matter.

Lens and Zoom: Flexible Enough for Versatile Adventures?

Being fixed-lens compacts, both cameras house a similar 5x optical zoom range equivalent to 28-140mm in 35mm terms.

Canon’s lens opens at f/3.9 to f/4.8, while Pentax starts slightly wider at f/3.5 closing to f/5.5 at full telephoto. That bit of extra brightness wide-open on Pentax edges advantage in low light or shallow depth-of-field play.

Macro shooting is fun with both - minimum focusing distance is about 1 cm, lending spectacular close-ups of small critters or water droplets. Canon’s lens stabilization (Optical IS) also improves hand-held macro sharpness, especially underwater, while Pentax surprisingly lacks image stabilization - a curious omission that can lead to softer images without a tripod or steady hands.

Both cameras lack lens mounts or interchangeable options - the limitation inherent to their category. But with their rugged focus, zoom versatility and decent aperture ranges make them fair all-rounders.

Video Capabilities: Shooting Your Adventures in Motion

Both cameras support Full HD 1080p video recording - Canon’s D20 at 24 fps, Pentax at 30 fps.

Canon supports slower frame rates up to 240 fps at 320x240 for slo-mo, while Pentax offers 60 fps at 720p, enabling smoother slow-motion playback.

Video stabilization is a tricky topic - Canon’s optical image stabilization helps smooth footage, but Pentax lacks built-in stabilization, making handheld video shakier.

Neither camera has microphone or headphone ports, limiting sound quality control, nor do they support 4K or advanced codecs.

Their ruggedness extends to video hiking, snorkeling, and action shooting, but forget about filmmaking ambitions here.

Battery Life and Storage: How Long Will It Last Out There?

Pentax offers a rated battery life of about 260 shots per charge with its D-LI92 battery pack, while Canon doesn’t specify officially but roughly matches this in real use.

Storage-wise, both rely on single SD/SDHC/SDXC card slots, covering standard expandable storage needs.

Neither camera has internal storage for images except Pentax’s minimal internal memory, which can help in emergencies.

USB 2.0 support ensures file transfer compatibility, and HDMI outputs enable easy preview on TVs.

Connectivity and Extra Features: Staying Connected in the Wild

Both cameras sport built-in GPS, a boon for travelers wanting GPS-tagged images without fuss.

They also include Eye-Fi card support for wireless image transfer - a bit niche now, but handy in 2013 when wireless meant scrambling for extra accessories.

No Bluetooth or NFC control here, which feels outdated today, but understandable for their release era.

Flash-wise, Pentax’s built-in flash reaches 5.4 meters, comfortably outranging Canon’s 3.5-meter flash. Likewise, Pentax includes a “soft” flash mode to soften harsh shadows.

Diving Into Genres: Which Camera Excels Where?

Waterproof cameras are versatile tools for different photography disciplines despite their compromises. Here’s how these two stack up across common types:

Portrait Photography

Canon’s face and eye detection combined with continuous AF help it edge ahead in capturing sharp portraits and pleasing skin tones. Its optical stabilization further helps when shooting handheld portraits.

Pentax does well but occasionally misfires on focus acquisition in complex scenes. Slightly higher sensor resolution offers crispness but noisier images in low light detract from skin tone smoothness.

Landscape Photography

Sharpness, dynamic range, and weather resistance matter here. Both cameras are weather sealed but Pentax’s crushproof rating plus anti-reflective screen make it slightly better suited for demanding terrains.

Pentax’s higher 16 MP resolution brings more detail in wide landscapes, but lack of manual exposure modes limits creative control such as long exposures or HDR.

Wildlife Photography

Autofocus speed and burst rate are crucial. Canon’s continuous AF and slightly faster real-world responsiveness outperform Pentax’s slower, less reliable AF system.

Neither camera excels at continuous shooting - Canon doesn’t specify burst numbers and Pentax stalls at 1 fps, so expect missed moments in fast action.

Sports Photography

Much like wildlife, Canon’s continuous focus would help but neither camera is designed for serious sports - low frame rates, small sensors, and limited manual controls restrict performance.

Street Photography

In street shooting, discretion, portability, and quick AF matter. Pentax’s slimmer body is more pocket-friendly, but slower autofocus and lack of continuous AF can cause delay.

Canon’s tactile buttons and faster AF make it more reliable for spontaneous street captures but at a slight ergonomic bulk cost.

Macro Photography

Both allow macro shots down to 1cm - very commendable for compacts. Canon’s image stabilization aids crispness, especially handheld underwater; Pentax’s missing stabilization requires a steadier hand or tripod.

I found Canon’s macro focus faster and more consistent in low contrast setups.

Night and Astro Photography

These cameras aren’t astro machines by any means, given sensor limitations and lack of manual modes. However, Pentax’s higher max ISO 6400 theoretically helps low-light shooting, but noise rises sharply.

Canon’s cleaner high-ISO images and optical stabilization make it slightly better for casual night shots.

Video Capabilities

Pentax supports higher frame rates in HD (up to 60 fps at 720p), while Canon offers slomo at lower resolution. Canon’s Optical IS improves handheld videos, favorable for action scenes.

Neither device includes audio inputs or advanced video controls.

Travel Photography

For travel, size, battery life, versatility, and ruggedness converge. Pentax’s lighter body and extra crushproof protection make it enticing for rugged trek travel.

Canon’s GPS tagging precision, optical stabilization, and live continuous AF give it an edge for diverse photo ops.

Professional Work

Neither aims squarely at pros, lacking RAW support, advanced exposure control, or extensive lens options. They serve niche enthusiasts and hobbyists well but can’t replace dedicated rugged mirrorless or DSLRs.
