Olympus TG-820 iHS vs Panasonic Lumix DC-S5: A Hands-On Comparison for Every Photographer

When I unpacked the Olympus TG-820 iHS and the Panasonic Lumix DC-S5 side by side for a thorough test, the immediate contrast was striking - not just in their physical presence, but also in their design philosophy and target audience. Having evaluated thousands of cameras over the years, each serving different disciplines and demands, this pair represents two distinct worlds. The rugged, compact waterproof Olympus TG-820 iHS contrasts vividly with the full-frame, professional-grade mirrorless Panasonic S5. Yet both have dedicated followers.

In this comparison, I’ll draw from extensive hands-on experience with both gear types, evaluating real-world use, technical details, and photographic impact. My aim is to cut through the specs jungle and help you pick the best companion whether you’re a casual traveler craving durability or a professional pursuing creative excellence. Along the way, I’ve integrated images and personal observations that shed light on these machines’ DNA.

Feeling the Difference: Size, Ergonomics, and Design Philosophy

The first impression always counts. The Olympus TG-820 iHS weighs under a quarter of a kilogram and fits comfortably in a jacket pocket. It’s the kind of camera you grab with one hand and take anywhere without hesitation - kakaka. Contrast this with the Panasonic S5, a solid 714 grams with an SLR-style grip and a comfortably chunky body designed for extensive manual control.

The image above illustrates the scale disparity clearly. The TG-820 iHS’s ultra-compact frame feels extremely nimble and unassuming on the city street or by the beach, built for adventurers and casual shooters who want zero fuss. Its physical dimensions (101 x 65 x 26 mm) make it one of the smallest rugged cameras you can get.

On the other hand, the S5’s bulk (133 x 97 x 82 mm) and heft make it a tool you hold deliberately - it invites you to slow down and craft your image carefully. Its grip and button placement allow confident one-handed operation even under demanding conditions, something I greatly appreciated during fast-paced portrait and sports sessions.

Moving your fingers over the controls reveals the design priorities: the Olympus uses a straightforward, minimal button layout suited to quick point-and-shoot operation, while the Panasonic features tactile dials and customizable buttons for manual exposure and focus, emphasizing creative freedom. The top plate comparison below underscores this.

If you appreciate physical feedback and the ability to tweak settings swiftly, the S5 welcomes you with open arms. The TG-820 iHS focuses on simplicity, sacrificing manual versatility for rugged portability and ease.

Peering Into the Heart: Sensor and Image Quality

What truly separates these cameras is their sensor technology. The Olympus TG-820 iHS sports a modest 1/2.3” CMOS sensor with 12 megapixels, designed primarily for convenience and durability, while the Panasonic S5 boasts a full-frame 24-megapixel CMOS sensor - a major step up in stature, resolution, and image quality.

The Panasonic’s sensor area is over 847 mm² compared to Olympus’s mere 28 mm² - that's roughly 30 times larger! This translates immediately into far superior dynamic range, tonal richness, and depth-of-field control. In practice, I found the S5’s images to have cleaner shadows, better highlight retention, and noticeably less noise at higher ISOs.

The TG-820 iHS is no slouch for snapshots under good light, offering decent sharpness and color fidelity for casual photography. However, under low light or when demanding deeper color gradations - critical in portrait or landscape work - it falls short. The high native ISO limit of 6400 on Olympus is rarely practical due to significant grain, whereas the Panasonic S5 can shoot cleanly up to ISO 51200 with its advanced sensor and image processing.

In real-world use, when shooting a moody sunset or dimly lit concert, the full-frame S5 allows a flexibility and image quality the little Olympus just cannot match.

Touching and Seeing: Screen and Viewfinder Experience

A camera’s screen is your window to compose, review, and adjust settings. The TG-820 iHS offers a fixed 3.0-inch HyperCrystal III TFT LCD with a modest 1030k-dot resolution, while the S5 features a fully articulating 3.0-inch touchscreen with an impressive 1840k-dot count.

I found the fully articulating touchscreen on the S5 to be an invaluable tool when shooting from unconventional angles, especially in macro and video work. Its responsive touch interface makes setting focus points and navigating menus swift and intuitive - the sort of experience that elevates workflow in the field.

The Olympus screen, while bright and clear in daylight thanks to its HyperCrystal technology, lacks touch capability and flexibility in position, which can occasionally hinder precise framing. The absence of any viewfinder on the TG-820 means you are always shooting via the screen, which is fine for casual snaps but taxing in bright conditions.

The S5’s electronic viewfinder (EVF) features a 2360k-dot resolution with 100% frame coverage and a 0.74x magnification - offering a sharp, immersive experience reminiscent of an optical SLR but enhanced by real-time exposure preview and focus aids. This made critical focusing and composition much easier for me during demanding portrait sessions and fast-moving events.

Autofocus and Performance: From Macro Close-Ups to Wildlife Action

Autofocus (AF) performance can make or break your shoot. The Olympus TG-820 iHS offers contrast-detection AF with face detection and limited autofocus continuous tracking, tailored for casual subjects. Manual focus is not supported, and AF points are unspecified.

The Panasonic S5, in contrast, wields a hybrid AF system employing 225 phase-detection points and contrast detection, plus eye, face, and touch tracking. It also supports focus bracketing, stacking, and post-focus function, which are incredible aids for macro and landscape photographers who want precise, layered sharpness.

During my wildlife field tests, the Panasonic’s continuous AF and 7 fps burst proved invaluable to capture fleeting moments - while the TG-820 iHS struggled with lag and focus hunting under dynamic conditions.

For macro photography, the Olympus’s 1 cm macro focus range and sensor-shift stabilization are effective for casual shots, but the Panasonic’s advanced sensor stabilization coupled with focus stacking capabilities opens new creative doors in the macro realm.

Shooting in the Wild: Weather Resistance and Durability

Where the Olympus TG-820 iHS shines unequivocally is ruggedness. It is waterproof (up to 10m), dustproof, shockproof, crushproof, and freezeproof. This camera is designed for harsh environments, from scuba dives to snowy mountaintops. If you require a camera that survives your adventures without a second thought, Olympus is a compelling choice.

The Panasonic S5 offers environmental sealing against dust and moisture but is not rated as waterproof or shockproof. It requires more care in the field, though well-suited for professional outdoor shoots thanks to its robust build materials.

For casual travelers or extreme sports enthusiasts who want to capture images without worrying about the elements, the TG-820’s hardened design is a huge advantage.

Versatility Across Genres: Portraits, Landscapes, Sports, and Beyond

Let's delve into how both cameras fare across key photography styles I routinely explore:

• Portraits: The Panasonic S5’s full-frame sensor provides superior skin tone rendition, beautiful bokeh thanks to wide apertures (being lens-dependent, but supported by the large sensor), and precise eye-detection AF. The Olympus, with its smaller sensor and slower lens, produces flatter backgrounds and less nuanced skin tones. For studio or location portraits, the S5 is a winner.

• Landscape: S5’s higher resolution and dynamic range excel with majestic scenes, enabling printing large, cropping, or heavy post-processing. Olympus’s compact size suits casual landscape strolls but can’t deliver the same depth or DR.

• Wildlife & Sports: Fast autofocus and burst rates matter. Panasonic’s continuous AF and 7fps beat Olympus’s 5fps with contrast-only AF. Moreover, the S5’s compatibility with telephoto Leica L-mount lenses expands reach and quality.

• Street: Here, the TG-820 iHS’s discreteness, light weight, and waterproof capability are real pluses - grab and go without attention. S5’s high-end performance is great but larger footprint attracts eyes.

• Macro: The S5’s focus bracketing and stacking outperform the TG-820’s basic 1cm macro focusing. Plus, image stabilization is more advanced on the Panasonic.

• Night & Astro: Again, S5’s sensor shines with high ISO usability and long exposure modes.

• Video: Panasonic’s 4K 60p video, along with microphone and headphone ports, make it a serious hybrid for videographers. Olympus caps at 1080p30 with no mic input.

• Travel: TG-820’s compact, rugged form is travel-friendly, but limited controls and image quality might frustrate enthusiasts. The S5 balances image quality and portability but packs a bigger bag and increased care demands.

• Professional work: Panasonic S5 ticks all the boxes for professionals with raw support, dual card slots, extensive customization, and compatibility with professional workflow.

Connectivity, Battery Life, and Storage: Essentials You’ll Use

Connectivity-wise, the Olympus is rather basic: no wireless features, USB 2.0, and HDMI out. No built-in GPS or Bluetooth. The Panasonic S5 sports built-in Wi-Fi, Bluetooth, dual SD card slots for backup or overflow, and USB-C charging compatible with high-power sources like power banks or laptop chargers - a thoughtful feature for long shoots away from AC power.

Battery life also favors the Panasonic with roughly 440 shots per charge compared to Olympus’s 220 shots. This is significant for longer days in the field.

Storage-wise, both use SD/SDHC/SDXC cards, but the S5's dual slots enable more professional workflows including overflow and mirroring.
