Olympus TG-320 vs Panasonic Lumix DMC-3D1: Real-World Comparison From a Hands-on Camera Veteran

Choosing a compact camera isn’t as straightforward as it used to be, even among models that seem targeted at casual photographers and adventurers. I’ve spent serious time in the trenches with both the Olympus TG-320 and the Panasonic Lumix DMC-3D1, putting them through their practical paces. This comparison is packed with insights you won’t just read on spec sheets - those little gotchas and perks that show up only when you’re actually shooting.

If you’re a photography enthusiast or even a pro looking for a secondary pocket camera for outdoor use or travel, I’ll show exactly how these two stack up across all major photography disciplines, real-world performance, and value. Let’s dive in.

Holding the Cameras: Ergonomics, Build, and Size Matters When You’re Out Shooting

First impressions count, and with these compacts, how they feel in your hands can make or break the experience, especially if you’re hauling them on hikes or around town. I carried both cameras on several day trips to get a feel for their real usability.

The Olympus TG-320 is the quintessential rugged compact. Its 96x63x23 mm frame hugs your hands modestly, and weighing just 155 grams, it’s a featherweight contender ready for the elements. Its tough credentials include waterproofing, freezeproofing, dustproofing, and shock resistance. It’s a camera for adventurous types who want to toss it in their bag without a care.

The Panasonic 3D1 is larger - 108x58x24 mm - and a bit heavier at 193 grams. It lacks any environmental sealing, which makes it less ideal for rugged use but feels a bit more advanced in handling. The slightly narrower body coupled with a longer grip feels stable but less grippy than the TG-320’s rubberized texture.

As top view comparison shows, buttons on the TG-320 are bigger and spaced out, friendly for fumbling thumbs in colder weather or with gloves. Panasonic’s controls appear more streamlined but smaller - good for discreet street shooting, though can be fiddly in a hurry.

Bottom line: If you want rugged reliability with confidence in bad weather or rough terrain, Olympus wins here. For slightly better handling in casual environments, Panasonic edges ahead but without protection against the elements.

Sensor and Image Quality: Tiny Chips but Big Differences in Output

With both cameras packing the modest 1/2.3" sensor size and similar sensor area (approx. 28 mm²), it’s tempting to assume image quality parity but that would overlook significant differences in sensor type, processor, and optimization.

• Olympus TG-320: 14MP CCD sensor paired with TruePic III+ processor. CCDs tend to offer high color fidelity but deliver noisier images at ISO above 400. The maximum effective ISO is capped at 1600 but usable performance rarely extends beyond 800. The sensor's resolution peaks at 4288x3216 pixels.

• Panasonic 3D1: 12MP CMOS sensor, allowing for faster readout and generally superior noise handling, paired with a more modern processing pipeline. Panasonic sets max ISO at 6400 (though realistically noisy) and resolution at 4000x3000 pixels.

In practical shooting, Panasonic’s CMOS sensor delivers cleaner images in low-light conditions, better dynamic range, and subtle color gradations. Olympus delivers punchier mids and slightly more contrasty shots - at the cost of pronounced noise in dim conditions.

Color depth and dynamic range (unofficial lab tests and subjective evaluation): Panasonic wins with a more flexible dynamic range capable of handling shadows and highlights better. Olympus can clip highlights faster under bright conditions but produces slightly warmer skin tones.

Screen and Interface: The Window to Your Shot

The rear LCD is where you see your image come to life, and an intuitive interface is crucial for quick adjustments and confirmation in the field.

The Panasonic 3D1 offers a bright 3.5" TFT full touchscreen with Anti-Reflective coating and a crisp 460k dots resolution. This makes composing and menu navigation fluid and enjoyable, especially for touch-savvy users. Features like touch autofocus and shutter release substantially speed up street shooting and macro work.

Olympus TG-320 sports a smaller 2.7" TFT LCD with just 230k dots resolution and no touchscreen capabilities. The screen’s noticeably dimmer and more reflective outdoors, which makes framing trickier in intense sunlight.

Menus on both cameras are straightforward, but Panasonic’s interface benefits from intuitive touch responses and faster transitions. Olympus opts for a more stripped-down physical-button driven approach - rugged, but slower to configure on the fly.

Autofocus System and Speed: Catch the Moment or Miss It

Moving subjects separate the amateurs from the skilled shooters. I tested both for single and continuous AF, face detection, tracking, and responsiveness.

• Olympus TG-320: Employs basic contrast-detection AF with face detection and selective tracking. Focus speed is sluggish, approximately 0.8 to 1 second in good light, slowing dramatically in weak light. No manual focus or fine adjustments are possible.

• Panasonic 3D1: Features a 23-point contrast-detection system with face detection, continuous AF, and touch AF support. Autofocus locks quickly (approx. 0.3 seconds in daylight) and tracks moderately fast-moving subjects with fewer misses.

Neither features phase-detection AF, so continuous tracking of fast action (sports/wildlife) is limited compared to modern hybrids or DSLRs. But Panasonic’s system feels distinctly more capable with faster autofocus acquisition and better accuracy for portraits and street photography.

Lens Performance and Flexibility: Fixed but Functional Zoom Ranges

Fixed lenses on compact cameras mean you get the ultimate portability but give up interchangeable options. How do these two lenses hold up in practice?

Olympus TG-320 sports a 28-102mm equivalent (3.6x zoom), f/3.5-5.1 lens. The wider end is decent for snapshots and landscapes, but the telephoto falls off in sharpness and suffers from chromatic aberration in high-contrast edges.

Panasonic 3D1 offers a 25-100mm equivalent (4x zoom), f/3.9-5.7, slightly wider at the wide end but a stop slower at maximum aperture, which matters in low light. Yet sharpness is better across the zoom range, with impressively controlled distortion and softer falloff at edges.

Neither camera has optical zoom stabilization, but both feature image stabilization: Olympus uses sensor-shift while Panasonic opts for optical IS. Panasonic’s optical IS delivers more consistent shake correction, especially at telephoto ranges during handheld shots.

Photo Quality Across Genres: Where Each Camera Shines

Portrait Photography

Portraits demand accurate skin tones, flattering bokeh, and responsive eye detection for tack-sharp eyes. Neither camera has advanced eye detection, but both feature basic face detection.

• The Panasonic 3D1’s CMOS sensor and image processor produce smoother skin tones and natural color reproduction. With faster AF and touch focusing, nailing facial focus is less stressful.

• Olympus TG-320 delivers warmer skin tones with a slight punch but suffers from slower focus and noisier images at wide apertures needed in indoor or dim portraits.

Bokeh quality is minimal on both due to small sensors and moderate max apertures; background blur is shallow at best. The Panasonic’s sharper lens edges often yield cleaner subject separation.

Landscape Photography

Here, dynamic range and resolution count more than speed or zoom.

• Panasonic 3D1 pulls ahead in dynamic range, capturing more shadow and highlight detail, important in landscapes with bright skies and dark foregrounds.

• Olympus’s rugged construction lets you shoot in harsher environments (rain, snow) with less worry, expanding seasonality.

• Both deliver similar resolution; Panasonic’s slightly better lens sharpness wins for finely detailed scenery.

Wildlife Photography

Wildlife shooting demands fast autofocus, accurate tracking, telephoto reach, and burst rates.

• Burst shooting is weak on both; Olympus manages one frame per second, and Panasonic’s continuous speed is unspecified but slow. Neither suits high-speed animal action.

• Telephoto reach is close, but Panasonic's four-times zoom with better stabilization edges it cautiously ahead.

• Autofocus tracking is better implemented on the Panasonic but still limited.

For serious wildlife use, you’ll want a more specialized camera, but for casual wildlife snaps, Panasonic’s setup is slightly more capable.

Sports Photography

Neither camera is designed for sports - frame rates and autofocus fall short of expectations.

• Olympus tops out at 1 fps with sluggish AF; you’ll miss many fast moments.

• Panasonic is quieter on specs but manual testing shows somewhat snappier AF with touch assistance but no burst.

Bottom line: Only casual sports photography is feasible with either.

Street Photography

For street shooters, discretion, lightweight portability, and quick shooting are key.

• Panasonic 3D1’s slim profile and touch interface make it stealthier and more adaptable in crowds.

• Olympus bulkier but sturdier; fingerprint-resistant surfaces prefer long days outdoors.

Panasonic wins on portability and ease of use, Olympus on durability.

Macro Photography

Close focusing distances matter here.

• Olympus TG-320 macro focusing at 3cm beats Panasonic’s 5cm range.

• Both lenses moderate sharpness at close distances; Olympus delivers punchier images, useful for flora/fauna macros.

• No focus stacking or focus bracketing features on either.

For casual macro, Olympus offers a tangible advantage.

Night and Astrophotography

High-ISO performance and long exposure support are critical.

• Olympus shutter speed tops at 1/2000s, with 4 seconds minimum. Panasonic shutter speeds range 1/60s to 1/1300s.

• Olympus max ISO 1600 is noisier; Panasonic shoots up to ISO 6400 but with grain.

• Neither camera supports RAW, limiting post-processing latitude - a major drawback for night shooters.

• Low-light autofocus is difficult on both; Panasonic’s faster focusing helps.

Neither are top choices for astrophotography enthusiasts.

Video Capabilities

If you dabble in video, Panasonic 3D1 delivers 1080p at 60 fps, a significant advantage over Olympus TG-320’s maximum 720p at 30fps.

Video quality from Panasonic is noticeably better in color and sharpness, plus its touchscreen aids quick focusing. Olympus videos appear softer and lack smooth motion.

Neither have external mic jacks; audio quality is basic in both.

Travel Photography

Travelers need versatility, decent battery life, compact size, and durability.

• Olympus shines with its weatherproof design, lighter weight, and tough body.

• Panasonic lasts longer on battery (200 shots vs. 150 for Olympus), but both are relatively modest.

• Panasonic’s larger, brighter screen adds to usability.

If you expect rough conditions, Olympus is the better travel buddy. For urban, touchscreen-loving travelers, Panasonic is appealing.

Professional Use

Neither camera targets professionals seeking sophisticated file formats or workflows.

• No RAW support on either, which is a significant limitation for editing flexibility.

• Both save JPEGs only, with relatively simple menus.

• No robust wireless features or tethering options.

Professionals might consider these cameras as casual backups or for quick snaps, but not for primary tools.

Reliability and Battery Life

Good battery life makes a difference when you’re away from power for hours.

• Olympus TG-320 runs about 150 shots per charge on its proprietary LI-42B pack.

• Panasonic 3D1 delivers roughly 200 shots per charge, which can be stretched with power-saving modes.

Both cameras use SD cards and have a single storage slot; Panasonic adds internal storage capacity.

Connectivity and Extras

Both cameras provide HDMI output and USB 2.0. No Wi-Fi, GPS, NFC, or Bluetooth - this limits wireless image transfer or geotagging convenience.

Price and Value: Cheapskate or Splurge?

• Olympus TG-320 has been discontinued and generally available second-hand or as low-cost new-old stock, often well below $150.

• Panasonic 3D1, although also an older model, commands a higher price (~$670 new), reflecting its 3D shooting and Full HD video features.

If budget is tight and you want a rugged camera for general snapshots, Olympus is the clear winner in value.

If you want better image quality, touchscreen convenience, and Full HD video, expect to pay premium.
