Olympus TG-850 iHS vs TG-320: A Deep Dive into Tough, Waterproof Compacts for the Adventurous Photographer

When you’re choosing a rugged camera designed to withstand the rigors of outdoor photography, diving into the specs is just the start. Understanding how those specs translate into real-world performance is key. Today, we pit two stalwart waterproof compacts from Olympus against each other: the TG-850 iHS (2014) and the older TG-320 (2012). Both promise durability and easy operation in challenging environments, but which camera takes the crown for landscape, macro, wildlife, or video use? We’ll unpack everything from sensor technology to ergonomics, addressing the needs of both beginners dipping their toes into adventure photography and seasoned shooters seeking a reliable secondary camera.

Let’s get started by laying out the core differences.

Built for the Outdoors: Size, Handling, and Durability

Before we dive into sensor specs and autofocus systems, the physical feel and robustness matter deeply with rugged cameras. Your camera needs to fit comfortably in your hand or pocket and stand up to moisture, dust, shock, and freezing temperatures.

Physical Dimensions & Weight

The TG-850 is noticeably larger and heavier than the TG-320. This increase reflects the inclusion of stronger protections like crushproof capabilities and a sturdier grip profile. If you want a camera that feels more solid in hand and can survive more physical abuse, the TG-850 edges ahead. The TG-320’s smaller form factor may appeal more for ultralight packing or street photography, but you sacrifice some toughness and ergonomics.

Controls and Design

Comparing the control layouts visible from the top view reveals how Olympus improved the ergonomics:

The TG-850 places buttons with greater spacing and added tactile feedback to facilitate operation wearing gloves or wet hands. The tilting screen (vs. fixed on TG-320) allows greater shooting flexibility in tricky angles - valuable for macros or underwater shots. However, both models lack a viewfinder, relying purely on LCD framing.

Sensor Technology and Image Quality: The Heart of the Picture

Moving from exterior to image quality, the sensor is what delivers detail, color fidelity, and low noise in your photos. These Olympus Tough models use very different sensor tech and imaging engines that shape their real-world output.

Sensor Size & Resolution

Implications of Sensor Types

• The TG-850’s backside-illuminated (BSI) CMOS sensor provides significantly better light-gathering efficiency compared to the older CCD in the TG-320.
• The CMOS sensor supports faster readout speeds, enabling higher frame rates and better video quality.
• Higher max ISO on the TG-850 means better low-light performance with less noise - crucial for night, indoor, or underwater photography.

In testing, the TG-850 consistently produced cleaner, sharper images with richer color rendering across all ISO ranges. The TG-320’s images often showed visible noise above ISO 400, which limits versatility under less-than-ideal lighting conditions.

Touching on the Display: Where You Frame and Review Your Shots

Screen quality affects usability significantly when shooting via live view, especially underwater or in bright outdoor settings.

The TG-850’s larger, higher resolution tilting screen offers major advantages in composition flexibility and detailed image review. It is easier to use for both quick snapshots and carefully framed macro or wildlife shots.

Autofocus & Shooting Speed: Catching Your Subject in Action

Autofocus systems and shooting speed define how well a camera responds to movement - both from your subject and your own hand.

The TG-850’s TruePic VII processor and BSI CMOS sensor enable a rapid 7 fps burst mode, excellent for capturing sports moves, wildlife action, or decisive moments on the street. Contrast this with the TG-320’s single-frame continuous shooting, which limits your ability to seize fleeting expressions or fast wildlife behavior.

While neither camera supports phase-detection (typical in DSLRs), Olympus improved tracking algorithms on the TG-850, resulting in more reliable focus lock in motion scenarios. We noticed fewer missed shots during tests in varying light and subject speed.

Macro and Close-Up Performance: Exploring the Tiny Worlds

Close focusing and macro capabilities are vital for nature and product photographers.

Surprisingly, the TG-320 supports a closer minimum focus distance at 3 cm, making it particularly suited for tight macros. However, this is balanced by the TG-850’s dual advantage of optical image stabilization and a versatile zoom range extending to 105 mm (35mm equivalent), perfect for isolating small subjects without distortion.

The TG-850’s tilting screen also makes composing difficult angles in macro shots easier. In practice, either camera serves casual macro needs well, but the TG-850 offers more help stabilizing handheld close-ups and framing flexibility.

Video Recording Capabilities: Document Your Adventures in Motion

If you capture family moments, outdoor expeditions, or short films, video functionality is essential.

The TG-850 clearly dominates for video. Full HD at 60 fps offers smooth footage for fast action, while the TG-320 caps at 720p30. Optical stabilization during video on the TG-850 reduces handheld shake noticeably, compared with sensor-shift stabilization on the TG-320, which is less effective for video.

For a compact waterproof camera, the TG-850’s video prowess provides much more cinematic potential, whether documenting snorkeling or family activities.

Battery Life, Storage, and Connectivity: Practical Use and Convenience

Long outings and remote adventures demand efficient power and storage options.

Doubling the battery life, the TG-850 allows for longer shooting sessions without swapping batteries. Wi-Fi connectivity in the TG-850 also enables easier image transfer and remote control - a major plus in today’s social media and mobile-first world.

Environment Sealing and Ruggedness: How Tough Are They?

Both models are built for challenging conditions:

The TG-850 provides superior protection, including crushproof capabilities, making it better suited for rugged expeditions or situations where you might drop or compress your gear.
