Pentax Optio WG-2: Slightly larger and chunkier at 122x61x30mm and 192g, it feels robust with a pronounced grip and textured exterior geared for durability. The WG-2’s dimensions allow for a more confident hold, especially when handling underwater, but it sacrifices a bit of stealth.

Ergonomics Takeaway: With both cameras designed for active use, I found the TG-610 better suited for pocket-carry and quick snaps, while the WG-2 offers extra grip security and ruggedness, crucial for demanding environments or underwater shoots.

Control Layout and User Interface: Navigating with Confidence

Operation speed and intuitiveness can be a make-or-break factor in the field, especially for action or wildlife photographers.

Neither camera sports external dials or advanced manual modes such as aperture or shutter priority, consistent with their consumer-friendly compact category. Both provide limited continuous shooting at 1 fps and lack RAW capture, which restricts post-processing latitude.

TG-610 Controls: The Olympus relies on a simple cluster of buttons and a four-way controller. However, no touchscreen or illuminated buttons mean menus can be fiddly under low light.

WG-2 Controls: Pentax integrates a four-direction keypad with slightly more tactile feedback and offers manual focus, an unusual boon in this class. Its physical controls felt more responsive during testing, especially underwater where tactile cues matter.

Interface Highlights: Olympus’s menus are clear but minimal. Pentax adds custom white balance and timelapse recording modes, widening creative possibilities.

Sensor Technology and Image Quality

The heart of camera performance lies in the sensor, influencing detail, dynamic range, color fidelity, and noise control.

• Olympus TG-610: Features a 1/2.3-inch CCD sensor at 14MP. CCD sensors typically deliver pleasing color with moderate noise control but lag behind CMOS technologies at higher ISOs. Max native ISO tops at 1600.

• Pentax WG-2: Upgrades to a 16MP 1/2.3-inch BSI-CMOS sensor - a back-illuminated design enhancing light gathering capabilities. ISO range extends up to 6400, theoretically aiding low-light shots.

Real-World Image Testing: Under daylight, both cameras produce adequate 14-16MP images with good sharpness for social sharing and casual prints. Olympus’s CCD renders slightly warmer tones, good for skin and landscapes. Pentax’s CMOS delivers cleaner images with less noise above ISO 800, making it more versatile in dim conditions.

LCD Screen and Viewfinding

Absent optical or electronic viewfinders limit compositions to screen framing.

• TG-610: 3-inch, fixed TFT Hypercrystal III LCD with 920k-dot resolution. It’s bright and fairly colorful, easing composition in varied light.

• WG-2: Also 3-inch but with anti-reflective coating and 460k-dot resolution. The coating helps in harsh sunlight, though the resolution is lower.

Screen Verdict: I preferred Olympus’s higher resolution screen indoors or low-light but noticed Pentax’s anti-reflection coating was better for direct sunlight shooting. Neither is touchscreen, so menu familiarity is key.

Autofocus and Focusing Features

Autofocus speed and accuracy are vital - whether you’re after a quick street portrait or elusive wildlife.

• Olympus TG-610: Contrast-detection AF only, with face detection and a multi-area AF system, but no manual focus. The AF is reliable but can be slow locking in low light or complex scenes.

• Pentax WG-2: Includes 9 contrast-detect AF points with face detection and manual focusing capability. I exploited manual focus during macro shoots effectively, especially underwater where AF can struggle.

Neither model has phase-detection AF or advanced tracking technology. Continuous AF is absent, limiting sports or fast-action performance.

Lens Characteristics and Versatility

Both cameras use fixed 28-140mm (equiv.) zoom lenses, covering a versatile 5x range situated well for travel, portraits, and landscapes.

• TG-610: Max aperture ranges f/3.9-5.9, slightly slower in the telephoto, impacting subject isolation and low-light performance.

• WG-2: Marginally faster lenses at f/3.5-5.5, and a macro focus range down to 1cm versus Olympus’s 3cm, which yielded noticeably sharper and tighter close-ups on flowers and insects in my testing.

The lack of interchangeable lenses limits creative scope, but the WG-2’s improved macro flexibility gives it an edge for nature lovers.

Image Stabilization and Burst Shooting

• Olympus TG-610: Offers sensor-shift image stabilization, a significant bonus in a rugged compact that translates directly to less blur handheld - useful in low light or telephoto shots.

• Pentax WG-2: Lacks built-in image stabilization altogether, making sharper telephoto shots more challenging without support.

Burst rates on both cameras are modest at 1 frame per second, not ideal for fast-moving subjects but workable for general purposes.

Video Capabilities

• TG-610: Captures 720p HD video at 30 fps in Motion JPEG format - a simpler codec with larger file sizes and less efficient compression.

• WG-2: Records 1080p Full HD footage at 30 fps and 720p at up to 60 fps, encoded in MPEG-4 H.264 for better quality and storage efficiency.

Neither camera offers microphone or headphone ports, limiting audio quality control. Video stabilization is unavailable on the WG-2 and likely rudimentary on the TG-610.
