Sensor Technology and Imaging Capabilities: Size, Resolution, and Real-World Output

The sensor is arguably the photographic backbone dictating image quality potential. The Olympus TG-310 employs a 14-megapixel, 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm with a total surface area of approximately 28.07 mm². This diminutive sensor constrains dynamic range and high-ISO noise performance under low-light conditions, with a maximum ISO of 1600 and no RAW support, relegating images to compressed JPEG output only. The manufacturer’s TruePic III+ image processor performs basic noise reduction and color rendering but is limited by hardware constraints. Consequently, image quality excels in bright daylight scenarios but degrades noticeably with higher ISO sensitivity or complex lighting.

The Panasonic G10 incorporates a larger Four Thirds CMOS sensor at 17.3 x 13 mm (approximately 224.9 mm²), nearly eight times the surface area of the TG-310 sensor. Its 12-megapixel resolution strikes a balance between detail capture and manageable file sizes. The larger pixel pitch permits superior noise control at elevated ISOs, reaching up to 6400 native ISO, while offering 14-bit RAW support for optimal post-processing flexibility. The Venus Engine HD II processor introduces advanced noise reduction algorithms and color fidelity enhancements, enhancing image quality in challenging lighting. The G10 handily outperforms the TG-310 in dynamic range, color depth, and low-light scenarios, making it suitable for professional-grade shooting where image fidelity is paramount.

Display and Viewfinders: Composing and Reviewing Imagery

In compositional interfaces, the TG-310 utilizes a modest 2.7-inch, 230k-dot fixed TFT LCD, sufficient for framing and image review but lacking articulating capability for creative shooting angles. The display’s resolution and screen size restrict precise manual focusing or detail assessment, particularly in bright outdoor conditions. Additionally, the absence of any electronic viewfinder precludes eye-level shooting, which can impede stability and framing precision.

Conversely, the Panasonic G10 offers a 3.0-inch, 460k-dot fixed TFT LCD coupled with a 202k-dot electronic viewfinder (EVF) covering 100% of the frame at 0.52x magnification. The EVF is a major practical advantage in bright environments, facilitating consistent framing and focus evaluation regardless of ambient lighting. While not the highest resolution EVF by modern standards, it is functional and eliminates reliance on the LCD in sunlight. The LCD itself provides crisp, vibrant previews conducive to critical image evaluation and menu navigation. For photographers frequently working outdoors or in bright urban environments, the G10’s viewing systems lend significant usability benefits.

Lens Systems and Compatibility: Fixed Versus Interchangeable

The Olympus TG-310’s fixed lens, with an equivalent focal range of 28–102 mm and a maximum aperture of f/3.9–5.9, limits photographic flexibility. This compact zoom suits everyday casual shooting but presents challenges for low-light, wide-aperture portraits, and telephoto reach beyond moderate zoom. The fixed lens also lacks manual focus capability, further constraining advanced compositional control. Macro focusing down to 3 cm provides some versatility for close-up photography, although without image stabilization enhancements beyond sensor-shift in-body stabilization.

By contrast, the Panasonic G10 benefits from the extensive Micro Four Thirds (MFT) lens ecosystem, with over 100 native and third-party lenses available, covering wide-angle, fast prime, versatile zooms, macro, and telephoto variants. This expansiveness allows professional customization tailored to genre-specific demands: portrait lenses with wide apertures for shallow depth of field, super telephoto zooms for wildlife and sports, and specialized optics for macro work. The G10 itself lacks built-in stabilization, but many native MFT lenses incorporate optical stabilization, mitigating camera shake effectively. Manual focus is fully supported, with focus peaking and magnification aids, facilitating precision critical for creative and technical photography.

Autofocus Systems: Speed, Accuracy, and Versatility in Varied Conditions

Autofocus (AF) efficacy is vital across nearly all photographic disciplines. The TG-310 employs a contrast-detection AF system with face detection capability but does not offer manual focus, focus tracking, or advanced AF area selection. AF is limited to single-shot mode, with no continuous AF or predictive tracking. This restricts its utility in fast-moving scenarios such as wildlife, sports, or street photography where subject movement requires dynamic focus adjustments. While suitable for static subjects or casual use, the TG-310’s AF presents constraints for photographers demanding speed and accuracy in complex environments.

In contrast, the Panasonic G10 integrates contrast-detection AF with continuous and single modes, face detection, and selective AF area customization, allowing refined control over focus points. While lacking phase-detection AF (common in higher-end models), its AF implementation remains responsive and reliable in good lighting. Continuous AF combined with a 3 fps burst mode enables competent tracking of moderately moving subjects, advantageous in wildlife or sports. Manual focus override with assistive focus peaking enhances precision. The G10’s AF capabilities, though not top-tier by today’s standards, substantially exceed those of the TG-310 and support a wide spectrum of shooting requirements.

Burst Shooting and Shutter Speed Range: Capturing Decisive Moments

The TG-310 supports only single-frame shooting at approximately 1 fps, with shutter speeds ranging from 4 to 1/2000 seconds. Its slow continuous shooting and limited maximum shutter speed restrict its capacity to capture rapid action or freeze fast motion effectively. This is a notable limitation for sports or wildlife photographers where frame rate and shutter responsiveness significantly influence image outcome.

The Panasonic G10 improves on this with a continuous shooting rate of approximately 3 fps and a shutter speed range extending from 60 seconds to 1/4000 seconds. While 3 fps is modest, it is sufficient for many entry-level action photography needs, particularly when coupled with selective autofocus tracking. The extended minimum shutter speed enables long exposures vital for night, astro, and creative photography. The presence of manual and priority exposure modes enhances creative control over shutter timing, directly impacting motion rendering and photographic intent.

Image Stabilization: Methods and Impact

The TG-310 incorporates sensor-shift image stabilization, compensating for handshake and minor movements, which is indispensable considering the small sensor and moderate lens aperture range. This results in notably improved handheld sharpness, particularly at telephoto focal lengths and slower shutter speeds. However, stabilization effectiveness is inherently limited by hardware generation and sensor size.

The Panasonic G10 lacks built-in image stabilization, relying instead on lens-based optical stabilization (OIS) available in some MFT lenses. While effective, this requires investment in stabilized glass, potentially increasing total system cost and complexity. Nonetheless, lens-based OIS often offers superior correction levels compared to early sensor-shift implementations, important in telephoto and video applications, though this depends on lens selection. For users shooting primarily handheld, stabilization strategy must consider this focal plane difference.

Video Capabilities: Compression, Resolution, and Practicality

Both cameras offer HD video capture capped at 1280 x 720 pixels at 30 fps, encoded in Motion JPEG format. This codec delivers acceptable image quality for casual recordings but is inefficient in file size and lacks advanced compression found in contemporary standards (H.264, HEVC). Neither camera supports 4K video recording, slow motion, or logging profiles.

Audio capabilities are limited; neither camera includes microphone or headphone ports, thus restricting audio quality options to onboard mono microphones. The Panasonic G10’s lack of in-body image stabilization affects video smoothness unless stabilized lenses are used, while the TG-310’s sensor-shift stabilization helps maintain handheld steadiness in casual video work.

Overall, these video specifications were standard for early 2010s models but are modest by current generation expectations, positioning both as supplementary video tools rather than primary filmmaking devices.
