The Olympus scores for touchscreen interactivity and slightly more modern UI elements, important for rapid subject acquisition and menu selection under pressure, while the Sony’s physical manual focus is a boon for precision-focused genres like macro.

Sensor Technology, Image Quality, and Optics

One of the core determinants of image quality is the sensor assembly combined with lens optics. Both cameras sport identical sensor sizes (1/2.3" or 6.17 x 4.55 mm), classified as small sensor compacts, but their sensor architectures and optics vary.

Sensor and Resolution

The Olympus VH-515 benefits from a BSI-CMOS sensor, known for improved light-gathering efficiency in dim conditions, delivering better high ISO performance and dynamic range relative to conventional CCDs found in the Sony G3. While the Sony nominally offers higher maximum ISO, the practical usability of those settings is limited by increased noise and reduced detail.

Lens Specification and Optical Performance

The VH-515 has a wider zoom spread starting at 26 mm, favorable for landscapes and travel, with a notably brighter maximum aperture at 2.8 on the wide end. This facilitates better low-light capture and shallower depth of field effects such as portrait bokeh. The Sony G3’s lens starts narrower at 35 mm equivalent and closes down to f/10 at telephoto lengths, restricting performance in low light and wide-aperture creative shooting.

Olympus’s sensor-shift stabilization is advantageous for handheld macro and slow shutter speeds, while Sony’s optical stabilization also significantly minimizes blur but is less versatile across focal lengths and shooting modes.

LCD Display and Viewing Experience

The rear display is the photographer’s primary framing and review tool in cameras without viewfinders.

• Screen Size and Resolution: Sony’s 3.5-inch display with 921K dots provides exceptional sharpness and visibility in bright conditions, while Olympus’s 3-inch screen with 460K dots lags behind in detail rendition.

• Touchscreen Responsiveness: Olympus’s touchscreen supports AF point selection and menu navigation intuitively. Sony’s display is fixed-type but lacks touch AF, relying on physical controls. This influences speed and user comfort in dynamic environments.

• Angle and Glare: Both models use fixed screens without articulation; however, Olympus’s TFT technology generally performs adequately outdoors though glare can be a factor. Sony’s display employs proprietary anti-reflective finishes that marginally improve usability under sunlight.

Autofocus System and Operational Responsiveness

AF speed and accuracy decisively impact photographic success, especially in dynamic scenarios such as wildlife or sports.

• Olympus VH-515: Employs contrast-detection AF with face detection capability and touch AF. AF modes include single and tracking AF, but lack more advanced options like eye or animal detection. The system is competent for static subjects but struggles with fast action, consistent with sensor and processor limitations.

• Sony DSC-G3: Also uses contrast-detection with 9 focus points, provides multi-area AF, but has no face or eye detection. Manual focus is supported, critical for technical genres such as macro or close-ups. However, AF speed tends to be slow, especially in low light.

Neither model offers phase-detection or hybrid AF systems common in recent cameras. Real-world tests reveal Olympus has a slight edge in AF acquisition speed due to processor advancements, but both cameras are unable to match modern compact or mirrorless autofocus performance.

Continuous Shooting and Shutter Performance

Capturing fast sequences is important in sports and wildlife photography.

Both cameras offer a modest 2 frames per second continuous shooting speed, insufficient for demanding sports or wildlife bursts but adequate for casual capture. Olympus offers a more expansive shutter range with a faster maximum shutter speed of 1/2000, enabling more selective exposure control or freezing action better than Sony’s 1/1000 ceiling.

Video Recording Capabilities

Video has become a major consideration even in compact cameras.

Olympus VH-515 clearly outperforms Sony in video recording, offering full HD resolution with modern compression (H.264) for manageable file sizes and decent quality. Sony’s video remains limited to low-resolution 640x480, which is obsolete by today’s standards and ill-suited for any professional or even casual video. Neither model provides external audio input/output, limiting sound quality control.

Battery Life and Storage Options

Compact cameras often vary widely in these fundamental usability factors.

• Olympus VH-515: Utilizes the proprietary Lithium-ion LI-50B battery; exact shot count not stated by manufacturer but generally rated for about 250-300 shots per charge. Storage uses SD/SDHC/SDXC cards - standard and versatile media widely supported.

• Sony G3: Uses proprietary battery (details unspecified), with storage options including Memory Stick Duo/Pro Duo and internal memory. Memory Stick format is less common and can complicate additional card purchases.

Given the ubiquity of SD cards and efficient power management in newer models, Olympus gains a logistical and convenience edge in extended use and media compatibility.

Connectivity and Wireless Features

The ability to transfer images or control cameras wirelessly has become integral.
