Olympus TG-820 iHS vs. Sony ZV-1: A Deep Dive into Two Very Different Compacts

When it comes to compact cameras, the market is a broad spectrum of specialized tools - from weatherproof adventure companions to high-performance imaging machines for creatives and content creators. Today, I’m rolling up my sleeves to compare two intriguing contenders from very different corners of the compacts universe: the Olympus TG-820 iHS and the Sony ZV-1.

Announced eight years apart, these cameras hail from distinct technological eras and target divergent user needs. The TG-820 iHS is a rugged super tough waterproof compact aimed at adventurers, while the ZV-1 struts its stuff as a compact powerhouse targeting vloggers and enthusiasts wanting big sensor quality without the bulk.

So, how do these two stack up in real-world shooting? Which deserves a place in your gear bag? Let’s unravel the mystery through a detailed comparison of their design, imaging tech, autofocus, performance across photography genres, and video chops.

Designing for Adventure or Creativity? Examining Form, Feel, and Control

At first glance (and first heft), these two might feel worlds apart. The Olympus TG-820 iHS is a compact toughie built to shrug off water, dust, shocks, crushing forces, and freezing temps. Its dimensions - 101x65x26 mm - and lightweight 206 grams make it pocket-friendly, almost like a rugged pocket knife in your gear arsenal. The fixed lens and streamlined controls mirror its purpose: simplicity and durability over complex handling.

The Sony ZV-1, while only slightly larger at 105x60x44 mm and heavier at 294 grams, boasts a considerably chunkier grip and more ergonomic control real estate for manual operation. It’s a “large sensor compact,” meaning it packs a bigger image sensor in what’s still definitely travelable size. Its fully articulating 3-inch touchscreen is flip-and-twist ready for selfies and vlogging, plus it supports manual focus and exposure modes.

Zooming in on control layout, the Olympus leans heavily on minimalism - fewer buttons, no touch input, and no viewfinder, all in service of ruggedness. The Sony offers more tactile buttons, customizable dials, plus touch AF and exposure control. It lacks a built-in viewfinder as well but makes up for it with a richer interface on the flip-out LCD.

For travel photographers debating size and ergonomic priorities, the Olympus will win for outdoor hauling ease and worry-free conditions; the Sony is slightly bigger but far more versatile for creative shooting.

Sensor and Image Quality: Small Sensor vs. Large Sensor Brilliance

Here’s where the generational and category gap widens notably. The Olympus carries a 1/2.3-inch (6.17x4.55 mm) CMOS sensor packing 12-megapixels. This sensor size - about 28 mm² - is common in tough compacts but inherently limited in dynamic range, noise performance, and high ISO sensitivity due to smaller photosites. It’s capped at ISO 6400 and lacks RAW shooting, a clear sign it’s designed for straightforward JPEG-based casual use.

Contrast Olympus’s sensor with Sony’s 1-inch (13.2x8.8 mm) BSI-CMOS chip on the ZV-1, boasting 20 megapixels, about 116 mm² - roughly four times the imaging area. This jump translates directly into better signal-to-noise ratio, richer tonal gradients, and extended ISO range from 125 native to 12,800 (boostable to 25,600). Crucially, Sony supports RAW files, offering professional-grade flexibility in post-processing.

In practical testing, this gap shows: the ZV-1 delivers crisper details, smoother gradations, and cleaner low-light performance. It’s versatile enough for large prints, cropping, and professional output. The TG-820 manages decent daylight snaps but struggles as shadows deepen or ISO climbs, lending itself best to casual, immediate sharing of adventurous moments where toughness matters more than pixel peeping.

The Display and User Interface: Screens That Suit Their Purpose

Both cameras offer a 3-inch LCD, but that's where similarities end. Olympus’s display is a fixed HyperCrystal III TFT panel with 1030k dots, providing good brightness and color in daylight but no touch responsiveness. It’s straightforward and reliably readable outdoors - an essential for adventure shooters.

Sony’s ZV-1, meanwhile, sports a fully articulated 3" screen with 922k dots and touch functionality, a boon for vloggers and photographers who want compositional flexibility and quick AF point selection right on screen. The flip-out design also means you can frame selfies or low-angle shots easily, a clear appeal to content creators.

In daily use, I found Sony’s touchscreen faster for focusing adjustments and navigating menus; Olympus’s screen is functional but limited by design choices aimed at durability.

Autofocus Performance Across Situations: Speed, Accuracy, and Tracking

In the autofocus realm, these cameras show their purpose-built distinctions again. Olympus TG-820 relies on contrast-detection AF with limited focus points and no phasedetection. It does feature face detection and “tracking,” but it’s a relatively basic system that struggles under tricky lighting or fast movement. Only single AF is available - not continuous AF during burst shooting. Manual focus is unavailable.

Sony’s ZV-1 comes loaded with a hybrid Phase Detection and Contrast Detection AF system, featuring 315 focus points and advanced subject tracking algorithms. It supports continuous, single, face, eye AF, and selective point focus modes. Plus, touch AF makes quick manual refinements a breeze. Despite lacking animal eye AF, the ZV-1’s rapid AF performance is superb, keeping pace with many entry-level mirrorless systems.

For photographers aiming at wildlife or sports, Sony’s autofocus is significantly more capable - tracking fast-moving subjects smoothly, minimizing hunting, and locking onto eyes for portraits. Olympus is better suited for still compositions or slower-paced adventure snaps.

The Lens and Zoom Experience: Versatility vs. Brightness

The TG-820 has a 5x optical zoom lens covering 28-140 mm equivalent focal length, aperture F3.9-5.9. The zoom range is respectable for a rugged compact but with relatively slow apertures, especially at telephoto. Macro mode allows focusing down to 1 cm, great for bugs or textures in the wild.

The ZV-1 sports a 24-70 mm equivalent zoom (2.9x), aperture F1.8-2.8 - markedly brighter across the entire zoom range. While the zoom range is tighter, the faster aperture is a big advantage for shallow depth-of-field control and low-light use. Its 5 cm minimum focus distance for close-ups is sufficient for casual macro shots but less extreme than Olympus’s.

Sony’s lens delivers superior bokeh and subject separation thanks to the wide aperture, ideal for portraits and vlogs looking to blur backgrounds elegantly. Olympus’s lens sacrifices this for zoom reach and rugged sealing, trading off creative flexibility for on-the-go utility.

Stability and Shutter Mechanics: Image and Video Smoothness

Both cameras provide some form of image stabilization. Olympus uses sensor-shift stabilization to reduce blur from hand shake, effective especially given the longer telephoto reach of its zoom. Sony uses optical stabilization integrated into the lens, yielding excellent stabilization for both stills and video.

Shutter speeds on Olympus run from 4 seconds to 1/2000 sec, with no electronic shutter options, limiting silent shooting capabilities. Sony offers from 30 seconds to 1/2000 mechanical, plus an electronic shutter allowing up to 1/32000 sec silent shots - great for shooting discreet moments or fast action with minimal distortion.

Olympus’s continuous shooting is 5 fps, decent for casual bursts. Sony crushes this with a blazing 24 fps in continuous mode, suited for sports or wildlife sequences.

Video: Feature-Rich ZV-1 Shines, TG-820 Is More Modest

If video is high on your list, the TG-820 records 1080p at 30 fps with modest bitrate and H.264 codec. There’s no microphone input, no advanced recording options, and no 4K whatsoever. It’s a handy feature for documenting adventures but lacks the sophistication for serious video work.

The Sony ZV-1 dazzles with 4K UHD video up to 30p, multiple bitrates, and high-frame-rate slow-motion 1080p at 120 fps. It supports XAVC S codec, has a microphone port for external audio, and delivers superior video autofocus thanks to the hybrid AF system and fast lens. Additional features include timelapse recording and advanced exposure controls.

This makes the ZV-1 a favorite among vloggers, YouTubers, and hybrid shooters needing pro-caliber video in a pocket-sized package.

Weather Resistance: Olympus’s Ruggedness vs. Sony’s Sophistication

In terms of durability, the Olympus TG-820 iHS is purpose-built for the extremes: waterproof to 10 meters, dustproof, shockproof (up to 2.1 m drops), crushproof (up to 100 kgf), and freezeproof down to -10°C. This makes it the ideal choice for hiking, snorkeling, climbing, or fieldwork in harsh environments.

The Sony ZV-1 lacks any official weather sealing. Its sophisticated electronics and larger sensor are vulnerable to moisture and dust intrusion, requiring more careful handling or protective housing outdoors.

Battery Life and Media: How Long Will You Shoot?

Olympus offers 220 shots per charge, which is reasonable but on the lower side for a rugged compact - bring spares if you plan a long day in the wild.

Sony ups this with about 260 shots per battery, slightly better but nothing exceptional given its advanced features and screen use.

Both use a single SD card slot (Sony also supports Memory Stick), so storage flexibility is basic but sufficient for most users.

Connectivity: Outdated vs. Modern Connectivity

Olympus TG-820 offers basic connectivity via USB 2.0 and HDMI with no wireless or Bluetooth options. You’ll have to physically transfer files, a constraint for instant social sharing.

Sony ZV-1 shines here with built-in Wi-Fi and Bluetooth for seamless smartphone pairing, remote control, and instant transfer - exactly what modern creators expect.
