Exploring the Olympus TG-320 vs Sony Cyber-shot HX20V: Compact Cameras Put to the Test

In the crowded landscape of compact cameras, two models from 2012 - the Olympus TG-320 and the Sony Cyber-shot HX20V - offer intriguing contrasts that cater to very different photography demands. While both lean toward casual and enthusiast users who prize convenience and versatility without the bulk of interchangeable lenses, their approaches to design, imaging capabilities, and features reveal a divergence worth dissecting. Drawing on hours of hands-on evaluation with both cameras, and a technical understanding of sensor technology and optics, this comprehensive comparison aims to give you clarity and confidence in deciding which camera best suits your photography goals - be it rugged outdoor use or extensive zoom reach for day-to-day versatility.

The First Impression: Built to Survive vs Built for Reach

Handling and Ergonomics: A Tale of Two Designs

Right out of the box, the Olympus TG-320 impresses with its rugged, tough-as-nails build tailored for adventure photographers who won’t risk a bulky DSLR or mirrorless in the wild. It boasts environmental sealing - waterproof, dustproof, shockproof, and even freezeproof - to soldier through conditions where most compacts would flinch. Weighing just 155 grams and measuring a tidy 96 x 63 x 23 mm, this model fits snugly in a jacket pocket or strapped to your gear without adding bulk or fatigue.

Compare that with the Sony HX20V, a slightly larger 254-gram unit with dimensions of 107 x 62 x 35 mm. It lacks any weather sealing, which frames it as a sophisticated superzoom for controlled environments rather than escapades into the wild. However, its extra heft accommodates a more substantial zoom lens and a bigger screen - details we’ll get to shortly.

Ergonomically, the TG-320’s compact chassis and lightly textured grip deliver reassuring confidence during extended handheld shooting in tough conditions. The Sony feels more substantial in hand, which may appeal to users who prefer a more traditional camera heft, especially when zoom corrections can be felt through the barrel.

Navigating Controls and Interface: Which Feels More Intuitive?

Moving to user interface, neither camera offers a touchscreen, but their control layouts tell us a lot about their priorities. The Olympus opts for simplicity - fewer buttons and a straightforward menu structure suitable for quick use when speed is critical. The Sony, conversely, sports a more complex layout with dedicated buttons for manual focus and exposure compensation, reflecting its target audience’s desire for creative control.

Looking at the top view of both cameras, the Sony’s buttons are well spaced, facilitating one-handed operation even when zooming or adjusting parameters on the fly. Conversely, the TG-320’s top is minimalist, appealing to beginners or those who want fewer distractions.

From practical experience, I appreciated the Sony’s button-driven customization options and manual focus ring, which proved useful in macro and telephoto scenarios. The Olympus’s simpler controls worked best in fast-paced outdoor use where ruggedness mattered more than customization.

A Close Look Under the Hood: Sensor and Image Quality

Sensor Technology and Resolution

Both cameras use the common 1/2.3-inch sensor format (6.17 x 4.55 mm sensor dimensions), which defines much of their image quality potential. However, the Sony HX20V features an 18-megapixel BSI-CMOS sensor - largely a step-up in sensitivity and noise control compared to the Olympus TG-320’s 14-megapixel CCD sensor.

The back-illuminated CMOS structure on the Sony improves light gathering efficiency, which should theoretically translate into cleaner images at higher ISO values and better dynamic range. The Olympus’s CCD sensor, while reliable, generally falls behind in low light responsiveness and noise suppression.

Hands-on image testing confirms these sensor differences. The Sony HX20V offers richer tonal gradations, more detail in shadows, and less visible noise up to ISO 800 compared to the TG-320, which struggles to maintain clean images beyond ISO 400. That said, the Olympus’s sensor delivers pleasantly sharp images under bright conditions due to the clarity of CCD capture - ideal for outdoor scenes under good light.

Display and Viewing Experience: Size and Clarity Matter

Neither camera incorporates a viewfinder - electronic or optical - but their rear LCD screens provide the framing and preview platforms.

The Olympus TG-320’s 2.7-inch TFT color LCD screen with 230k-dot resolution is serviceable but limited in sharpness and outdoor visibility. In contrast, the Sony HX20V’s 3-inch XtraFine TruBlack TFT LCD boasts a 922k-dot resolution, providing a noticeably clearer and more vibrant display with improved contrast, especially helpful under sunlight.

This difference means that for critical focus checking or composing in bright conditions, the Sony HX20V holds a distinct advantage. However, users prioritizing ruggedness over screen fidelity might find the Olympus’s display adequate for the job.

Zoom, Lens, and Macro Abilities: Optical Reach vs Robust Simplicity

The Olympus TG-320 sports a 28-102 mm equivalent lens with a modest 3.6× optical zoom, aperture ranging from f/3.5-5.1. Its macro focus range starts at 3 cm - a respectable close-focusing distance for a rugged compact.

The Sony HX20V shines with its 25-500 mm (20×) superzoom lens - offering incredible reach from wide-angle landscapes to distant wildlife and sporting events. Aperture varies from f/3.2-5.8, typical for extensive zoom lenses. Its macro mode astonished me with sharp close focus at just 1 cm from the subject, delivering detailed shots with lovely background separation.

This zoom versatility is a major strength of the Sony, opening doors to genres like wildlife or sports photography where reach matters. Yet, the Olympus’s wider aperture at the short end and consistent performance in tricky outdoor environments remain its key appeal.

Autofocus Performance: Speed, Accuracy, and Tracking

Both cameras employ contrast-detection autofocus systems - common in compacts of this era. The Sony offers nine focus points and supports center-weighted, multi-area, and spot focusing modes, plus face detection. Olympus provides face detection as well but fewer AF area options and unknown explicit focus points.

In real-world testing, the Sony’s autofocus was noticeably faster and more accurate, especially when tracking moving subjects or in low-contrast scenes. The Olympus’s autofocus tended to lag, occasionally hunting in lower light and struggling to lock on quickly, partly due to sensor limitations and less sophisticated AF algorithms.

This gap means wildlife and sports shooters will benefit from the Sony’s quicker burst mode (10 fps vs. TG-320’s 1 fps) combined with improved AF tracking, making it a more capable choice for action photography. Meanwhile, the Olympus is better suited for relaxed shooting or static subjects outdoors.

Image Stabilization: Sensor-Shift vs Optical

Both cameras feature image stabilization intended to reduce blur from hand shake.

The Olympus TG-320 uses sensor-shift stabilization moving the sensor to compensate for handheld motion - a method effective for general use but less so when reaching higher zoom levels. The Sony implements optical image stabilization integrated into the lens assembly, proven to be more effective for superzoom cameras to keep telephoto images sharp.

In field tests, the Sony’s optical stabilization allowed me to reliably handhold at 500 mm equivalent focal length with minimal blur, a feat the Olympus cannot approach given its limited zoom range and sensor-shift tech.

Video Capabilities: HD Quality and Formats Compared

If video is part of your photography toolkit, differences become more apparent.

The Olympus TG-320 captures video at 1280×720 resolution at 30 fps (HD), saving files in MPEG-4 and H.264 formats. The Sony HX20V stepped up with full HD video recording at 1920×1080 pixels at 60 fps, supporting AVCHD and MPEG-4 compression formats.

Though neither model includes microphone input or headphone jack for audio monitoring, the Sony’s higher frame rate and resolution yield more professional-feeling footage suitable even for casual videographers or travel bloggers. The Olympus video is limited for anyone expecting contemporary quality.

Connectivity and Extras: GPS, Memory, and Wireless

The Sony HX20V features built-in GPS - a boon for travelers and photojournalists keen on geotagging images and organizing content based on location. It also supports Eye-Fi wireless connectivity cards for easy photo transfer, though it lacks native Wi-Fi or Bluetooth by modern standards.

The Olympus in contrast does not offer any wireless connectivity or location services. It provides USB 2.0 and HDMI ports for tethering and playback, mirroring Sony’s external connection options.

Both cameras accommodate SD/SDHC/SDXC cards; Sony also supports proprietary Memory Stick formats, expanding flexibility.

Battery life favors the Sony appreciably - around 320 shots per charge versus Olympus’s modest 150 shots, a vital consideration for extended trips or events requiring long shooting periods without recharging.
