Olympus TG-310 vs Sony A6600: A Deep Dive into Two Very Different Cameras

In the diverse world of digital photography, it's not uncommon to compare devices that occupy vastly different niches. Today, I’m tackling exactly that. On one hand, we have the Olympus TG-310 - a compact, rugged waterproof camera designed for casual adventurers who want a simple, durable point-and-shoot. On the other, the Sony A6600, a sophisticated mirrorless powerhouse tailored toward enthusiasts and professionals demanding top-tier image quality, speed, and versatility.

I’ve personally tested both extensively across multiple real-world scenarios, scrutinizing every facet from sensor technology and ergonomics to autofocus finesse and overall handling under pressure. So, if you’re caught between a grab-and-go rugged compact or a serious mirrorless system for creative expression, this comparison aims to illuminate where each camera shines and where it falls short.

Getting a Feel: Size, Handling, and Ergonomics

The moment you hold these two cameras, it’s clear they’re engineered for wildly different user experiences and use cases.

The Olympus TG-310 is pocket-friendly at just 96 x 63 x 23 mm and a featherweight 155 grams. Naturally, it emphasizes portability and durability, encased in a rugged shell that’s waterproof, freezeproof, dustproof, and shockproof to a reasonable extent. The ergonomics favor those who want quick snapshots without fiddly controls - there’s no manual exposure, just basic dial and button inputs.

Compare that with the Sony A6600, which sports a rangefinder-style mirrorless body measuring 120 x 67 x 69 mm and weighing in at 503 grams. This is a thoughtfully designed camera with a deep grip and a sprawling layout of buttons, dials, and wheels. The A6600’s build quality is robust but not weather-sealed to the degree of the TG-310. It’s designed for extended shooting sessions, demanding manual control, and lens versatility.

The TG-310’s minimalism is a strength if you’re hiking, snorkeling, or traveling light. On the flip side, the A6600 feels like a companion for serious photographers who want that tactile feedback and customizable interface. For anyone transitioning from DSLRs or higher-end mirrorless models, the Sony’s control layout will feel instantly familiar.

Top-Down: Control Layout and Operational Flow

Peeling back the layers of control, the difference in approach becomes even more evident.

With the TG-310, Olympus kept it simple - no touchscreen, a basic 2.7-inch fixed TFT LCD with 230k dots, and very limited physical buttons. It’s a point-and-shoot through and through. Modes are limited - no manual aperture or shutter priority; shooting is basically auto or scene presets. The flash is built-in with a modest 4.2m range, and there’s no external flash support.

On the other hand, the A6600 features a sophisticated tilting 3-inch touchscreen LCD with 922k dots for critical image evaluation. It packs an electronic viewfinder (EVF) with excellent 2.36M-dot resolution and full 100% coverage - vital for precise composition in bright outdoor conditions. The Sony’s top plate is populated with dials for shutter speed, exposure compensation, ISO, and customizable function buttons.

The Sony also delivers full manual control alongside aperture and shutter priority, offering the kind of flexibility professionals demand.

My testing found the A6600’s menus and button configurations to be highly intuitive for those familiar with advanced cameras, although newcomers may face a minor learning curve. Meanwhile, the TG-310 is distraction-free; if you want a straightforward photography experience, it won't let you down, but pros will quickly find it limiting.

Sensor Technology: The Heart of Image Quality

To put this bluntly: the cameras inhabit opposite ends of the sensor performance spectrum.

The Olympus TG-310 uses a 1/2.3-inch CCD sensor - a small chip measuring just 6.17 x 4.55 mm, with an area under 29 mm². It offers 14 megapixels with a modest max ISO of 1600. CCDs are increasingly rare today, replaced by CMOS sensors that bring better noise and speed performance.

In contrast, the Sony A6600 features a substantially larger APS-C sized CMOS sensor (23.5 x 15.6 mm, around 366 mm²) with 24 megapixels. This sensor benefits from back-illuminated technology, improving low-light and dynamic range performance. Sony backs this with its Bionz X processor, which delivers reflected speed and noise efficiency.

I ran side-by-side lab tests shooting flat-field charts, noise targets, and dynamic range steps. The A6600 dramatically outperforms the TG-310, providing cleaner files at ISO 3200 where the TG-310 struggles noticeably even at ISO 400. Dynamic range is similarly wider on the Sony, producing richer tonal gradations and better highlight recovery.

This makes the A6600 much more appealing for demanding shots - think landscapes with subtle sky gradients or portraits requiring delicate skin tone rendition in mixed light. The TG-310 is adequate for snapshots but will disappoint anyone expecting professional-level image fidelity.

LCD and Viewfinder: Composition and Playback

Shooting through the Olympus TG-310 means relying fully on its fixed 2.7-inch rear LCD with modest resolution and no viewfinder. The screen’s readability suffers in bright sunlight, and there's no scope for composing images through a viewfinder - a notable inconvenience for some shooting disciplines like street or wildlife photography.

The Sony A6600 grants enthusiasts an articulated, tilting 3-inch touchscreen LCD complemented by a sharp electronic viewfinder (EVF). The EVF allows precise framing and manual focus confirmation even in blinding sun.

In field use, I found the A6600’s touchscreen and EVF critical for focusing in tricky scenarios such as low light or macro photography, where precision is key. The TG-310’s simpler approach encourages quick snaps but can frustrate those wanting to shoot more deliberately or use manual focus aids.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus (AF) technology is an evolutionary tale here.

The TG-310 employs a basic contrast-detection AF system with limited focus modes - single AF and face detection through live view, but no phase detection, no continuous AF during video, no animal eye tracking, and only rudimentary tracking capabilities.

The A6600 bursts past with a hybrid AF system combining 425 phase-detection points and 425 contrast-detection points, covering near 84% of the frame. Importantly, it features real-time eye autofocus for humans and animals - a game-changer for portrait and wildlife photographers. Continuous AF tracking at 11 frames per second (fps) pairs speed with precision, essential for sports and fast action.

I tested both cameras across several vigorous real-world AF scenarios: moving children in a playground, birds in mid-flight, and street action in fading light. The A6600 nailed focus almost instantly with excellent subject tracking, while the TG-310 frequently lagged or hunted - unsurprising given its compact sensor and aging AF tech.

Burst Shooting and Speed

When fast shooting counts - for sports or wildlife - framerate is a crucial spec.

The Olympus TG-310 can only manage a sluggish 1 fps continuous shooting mode, basically restricting you to single shots.

The Sony A6600’s 11 fps burst with continuous AF and exposure tracking outclasses many cameras in its class, rivaling flagship models at a fraction of the price.

This difference alone decides the suitability of each camera depending on your shooting needs. Wildlife and sports photographers will find the TG-310’s speed dangerously limiting.

Image Stabilization and Macro Capability

Stabilization helps prevent blur from camera shake, especially in low light or macro photography.

The Olympus TG-310 offers sensor-shift stabilization, somewhat helpful at its focal lengths (28-102mm equivalent), but its macro mode is limited to 3 cm minimum focusing.

The A6600 boasts Sony’s 5-axis in-body image stabilization, which is notably more effective and compatible with a broad range of lenses. Coupled with its extensive lens lineup, this makes macro and close-up shoots much more practical and sharp.

Video Features and Capabilities

If video is a priority, you need to weigh the capabilities carefully.

The TG-310 outputs 720p HD video at 30 fps using Motion JPEG format - basic by today’s standards, with no external microphone input or advanced exposure controls during video. It’s fine for casual clips but limited for extended or professional-level video.

Meanwhile, the A6600 shoots 4K UHD (3840 x 2160) at 30fps using efficient XAVC S codec, with full pixel readout and no pixel binning - delivering crisp, detailed footage. It supports full manual exposure control during video, S-Log3 profiles for color grading, and has microphone and headphone jacks for pro audio monitoring.

For stop-motion or timelapse work, the A6600 even has built-in timelapse recording - a feature the TG-310 lacks.

Build Quality and Durability

The Olympus TG-310’s rugged credentials are carved in stone: waterproof to 10m, freezeproof to -10°C, shockproof up to 1.5 m drops, and dustproof sealing make it a hardy adventurer’s ally.

The Sony A6600, while solidly built with some degree of weather sealing (magnesium alloy body), is not designed for harsh outdoor abuse. It demands careful handling or protective housing in extreme environments.

Lens Ecosystem and Compatibility

Here lies a decisive gap.

The TG-310 is a fixed-lens camera - you’re stuck with its 28-102mm (equivalent) f/3.9-5.9 zoom. That’s convenient without faffing but limits creative possibilities or specialized uses like ultra-wide landscapes or super-telephoto wildlife.

The Sony A6600 uses the Sony E-mount system, giving access to over 120 lenses from Sony and third parties - prime lenses, zooms, macro, portrait, wide-angle, telephoto, you name it. This versatility means you can tailor your setup to literally any genre of photography without compromises.

Battery Life and Storage Options

Battery life can make or break long shooting days in the field.

The TG-310 offers approximately 150 shots per charge - sufficient for casual use but limiting for extended trips without spares.

The A6600 excels here, rated for around 810 shots per charge thanks to its powerful NP-FZ1000 battery. This is a boon if you’re shooting weddings, events, or day-long excursions.

Both cameras use SD cards for storage, but only the Sony allows Memory Stick Pro Duo compatibility, too. Neither has dual card slots, which is notable for professional reliability.

Connectivity and Wireless Features

Connectivity has become a modern must-have feature.

The TG-310 includes Eye-Fi card compatibility for wireless image transfer, a slightly dated solution by today’s standards.

The Sony A6600 possesses built-in Wi-Fi, Bluetooth, and NFC for instant image sharing, remote control via smartphone, and fast transfers to computers or cloud services. These features significantly improve workflow efficiency.

Price and Value Assessment

Pricing reflects the cameras’ intended markets and capabilities.

While the TG-310 is typically an inexpensive compact camera (often available under $150 used), the A6600 commands a premium - around $1200 body only at launch, reflecting its advanced sensor, AF across numerous lenses, and extensive feature set.

That said, the A6600 is excellent value for enthusiasts and pros seeking a serious mirrorless platform, especially given Sony’s continuous firmware updates, lens ecosystem, and video capabilities.
