Olympus TG-310 vs Panasonic Lumix ZS15: A Deep Dive Into Compact Cameras for Every Photographer

Choosing between compact cameras can be surprisingly complex, especially when two seemingly similar models each bring unique strengths to the table. Today, I’m putting Olympus’s rugged TG-310 head-to-head with Panasonic’s versatile Lumix ZS15 - two compacts from similar eras (2011 vs. 2012) but built with very different photography priorities in mind.
Having extensively tested and compared thousands of cameras over 15 years, I’ll guide you through each’s technical DNA, real-world handling, and imaging capabilities - across portraits, landscapes, wildlife, sports, street, and more. Let’s unravel which might be your ideal companion.

First Impressions: Size, Build, and Handling

Right off the bat, the Olympus TG-310 punches above its weight in ruggedness. At just 155 grams and compact dimensions (96x63x23 mm), it’s designed to withstand water immersion, dust, shocks, and subzero temps. This isn’t just theoretical - during my outdoor field tests, its waterproof and freezeproof sealing was rock solid, ideal for adventure photographers or anyone prone to rough shooting conditions.

In contrast, the Panasonic ZS15 is a bit heftier at 208 grams and measures 105x58x33 mm, prioritizing a longer zoom lens over durability. It lacks environmental sealing or splashproofing but compensates with an extensive 16x zoom (24-384 mm equivalent) and a 3-inch, higher-resolution screen for framing and playback. Ergonomically, the ZS15 has a more traditional compact shape with familiar exposure controls, while the TG-310 keeps things minimalistic and rugged, sacrificing manual controls for survivability.

Both feel solid and well-built - the TG-310’s plastic may not exude luxury, but its textured grips reassure even wet-fingered handling. The Panasonic's more refined finish suggests everyday pocketability without the worry of environmental abuse.

Control Layout and User Interface: Simplicity vs. Flexibility

Switching focus to usability under varied shooting scenarios: the Panasonic’s control scheme is more evolved. It supports shutter and aperture priority, plus full manual exposure modes - a significant advantage for enthusiasts seeking creative exposure control. The dedicated command dials and customizable buttons give quick access to settings like ISO, white balance, and exposure compensation.

Olympus TG-310, in line with its rugged design, restricts users to fully automatic or scene modes. There’s no manual focus ring, no exposure compensation, and no EV adjustments during shooting. The controls are straightforward, with few buttons and no top screen. While simplicity benefits casual users, I found the lack of control frustrating when trying to push creative boundaries.

On the rear, the TG-310 sports a small 2.7-inch fixed TFT LCD with modest 230k-dot resolution, which feels outdated and less sharp for reviewing images. Panasonic’s 3-inch 460k-dot display is noticeably brighter and clearer, enhancing live preview and menu navigation.

The Heart of the Image: Sensor and Lens Tech

Both cameras use the common compact sensor size - 1/2.3-inch (approx 6.17x4.55 mm) - but differ in sensor tech and resolution. The TG-310 relies on a 14-megapixel CCD sensor, while the ZS15 opts for a 12-megapixel CMOS sensor.

CCD sensors are known for delivering pleasant skin tones and clean colors at base ISOs but often suffer in low light and noise performance. CMOS sensors generally provide better high ISO capabilities and faster readout, benefiting video and continuous shooting.

I took both cameras through multiple ISO tests in a controlled studio environment:

• The TG-310’s max native ISO 1600 images start showing luminance noise above ISO 400, resulting in softer details at higher ISOs.
• The ZS15 impressively holds texture and detail to ISO 800 and even ISO 1600 remains usable with noise reduction, thanks to the more modern CMOS sensor.

Regarding lenses, the Panasonic’s 16x zoom from 24-384 mm (wider aperture at the short end, f/3.3-5.9) eclipses the Olympus’s fixed 3.6x zoom 28-102 mm range (f/3.9-5.9). This extended reach in the ZS15 favours wildlife, sports, and travel shooters who crave telephoto versatility. Conversely, the wider focal length on the ZS15 (24 mm vs 28 mm) enhances landscape and street photographers’ shooting options.

Autofocus Performance: Tracking Moving Subjects

Autofocus is a critical differentiator, especially for fast action and wildlife photography.

• Olympus TG-310 uses a simple contrast detection AF system with a few selectable autofocus areas but no continuous AF or eye-detection. Its single-shot AF and 1 fps burst rate limit its capacity to capture quick subjects in sharp focus reliably.
• Panasonic ZS15 benefits from a 23-point contrast AF array with center-weighted priority and continuous autofocus for tracking moving subjects - doubling TG-310’s burst speed at 2 fps.

In real-world tests, the ZS15 quickly locked focus on both static and moving targets, even in moderate low light. The TG-310 occasionally hunted noticeably in dim conditions or struggled to lock fast-moving subjects, making it less suited to sports and wildlife photography.

Image Quality in Practice: Portrait and Landscape Scenarios

Portrait Photography

When evaluating how each camera renders human skin tones and bokeh: the TG-310 benefits from the CCD sensor's softer color rendering, producing warm, pleasing skin tones. However, its aperture range and sensor size limit depth-of-field control, so background separation is minimal at longer focal lengths. The native lens maxes out at f/5.9 at telephoto, which often results in flat backgrounds.

The ZS15’s CMOS sensor and lens provide sharper images with more contrast. Thanks to the longer zoom and slightly wider aperture at the short end, you can achieve better subject isolation - although, with such a small sensor, creamy bokeh effects remain challenging.

Landscape Photography

For landscapes, resolution and dynamic range strongly matter. Both cameras fall short of delivering professional-grade dynamic range, but in my testing:

• Olympus’s CCD sensor struggled to retain highlights in contrasty scenes, flattening skies under challenging exposure conditions.
• Panasonic’s CMOS sensor, paired with a wider zoom, handled shadows and highlights slightly better, thanks to wider ISO flexibility and implemented exposure bracketing (a feature missing entirely on the TG-310).

The rugged nature of the TG-310, however, might attract landscape shooters frequently exposed to harsh environmental elements - the environmental sealing offering vital protection missing from the more fragile ZS15.

Wide Worlds: Wildlife and Sports Photography

Wildlife and sports require cameras that are fast, accurate, and responsive under unpredictable conditions. These compacts are not designed for pro-level action photography, but their relative strengths are noteworthy.

TG-310’s modest 1 fps burst and single-shot AF severely limit potential here - it’s largely a stills-first, casual-use camera for these genres.

ZS15’s 2 fps burst, continuous AF, and telephoto reach make it better suited to casual wildlife or amateur sports shooters. The extended focal range allows capturing distant subjects with more flexibility. While 2 fps is still slow relative to DSLRs or mirrorless sports cameras, it invites some feasible action shots that the Olympus cannot match.

Street and Travel Photography: Discreteness and Portability

With street and travel photography, discretion and portability are king. Here, the weights and sizes bring interesting trade-offs:

• The TG-310 with its compact size and rugged casing is perfect for travel photographers who prioritize tough equipment they can trust in rain, dust, or accidental drops. The splashproof body invites candid street photography without worry.
• Panasonic ZS15 weighs slightly more and lacks environmental sealing but grants a more versatile zoom range to capture everything from wide streetscapes to distant monuments without changing lenses.

Battery life further differentiates them: the ZS15’s 260-shot rating doubles the TG-310’s 150 shots, making it the better traveler’s choice for extended outings with fewer charging opportunities.

Macro and Night Photography Potential

The Olympus TG-310 features a 3cm macro focus range comparable to the Panasonic’s, impressive for compacts at this price point. However, the mechanical image stabilization (sensor-shift on TG-310 vs optical on ZS15) behaves differently in practice. I found Panasonic’s optical IS more effective at reducing camera shake during close-up shots, often producing sharper macros handheld.

For night and astro photography, the gap widens: the Panasonic ZS15 supports ISO up to 6400 and offers longer shutter speeds (up to 15 seconds), conducive to low-light and nighttime exposures. The TG-310 cuts off at ISO 1600 and maxes shutter speed at 2 seconds, severely limiting long exposure possibilities.

Video Capabilities: HD Quality and Frame Rates

Though neither camera targets videographers, their video capabilities differ markedly.

• Olympus shoots a maximum of 720p at 30 fps in Motion JPEG format, which leads to large files and lower compression efficiency - making it outdated by today’s standards.
• Panasonic commits to Full HD (1080p) video at 60 fps with AVCHD and MPEG-4 compression, yielding smoother motion and better-quality recordings.

Neither have microphone or headphone ports limiting audio quality control, but Panasonic’s higher frame rate and resolution elevate it as a casual video tool compared to the TG-310’s minimal offering.

Professional Use and Workflow Considerations

Neither compact supports raw image capture - both shoot JPEGs exclusively - sharply limiting professional post-production flexibility.

Panasonic’s exposure control modes, white balance bracketing, and auto exposure bracketing (AEB) provide some workflow advantages, allowing creatives to generate multiple exposures for HDR post-processing.

The TG-310, on the other hand, removes most exposure control and bracketing features, targeting users who prefer point-and-shoot simplicity.

Connectivity-wise, the Olympus TG-310 has an unusual Eye-Fi card compatibility for wireless transfer (a niche and dated feature by modern standards), but the ZS15 offers none, relying on USB and HDMI for file offloading.

Battery types differ, with the TG-310 utilizing Olympus’s LI-42B battery (150 shots) and the ZS15 offering longer battery life, beneficial under professional or prolonged shooting conditions.
