Olympus TG-860 vs Panasonic ZS20: The Ultimate Compact Camera Face-Off for Enthusiasts and Pros

When diving into the world of compact cameras with superzoom capabilities, the Olympus Stylus Tough TG-860 and the Panasonic Lumix DMC-ZS20 stand out as intriguing contenders - both boasting features aimed at different user needs but sharing a similar ethos of versatility on the go. Having spent countless hours testing compact and bridge cameras alike, I wanted to explore these two models side-by-side, peeling back specs and real-world usability to help you decide which one deserves space in your bag.

Let’s embark on this detailed comparison journey together - covering everything from sensor tech and lens reach to ergonomics, shooting disciplines, and value. By the end, you’ll understand not just what these cameras offer on paper, but how they truly perform in the field.

First Impressions: Size, Build, and Handling

At a glance, both the Olympus TG-860 and Panasonic ZS20 fit comfortably into the compact camera realm, designed with portability in mind. However, the TG-860 brings something special to the table: ruggedness. With environmental sealing that makes it waterproof, shockproof, freezeproof, and crushproof, it is clearly built for adventures where your camera might take a beating.

Physically, the TG-860 measures 110 x 64 x 28 mm and weighs 224g, slightly chunkier than the sleeker Panasonic ZS20 at 105 x 59 x 28 mm and 206g. The ZS20 favors a more traditional compact look without weather sealing, which keeps it on the lighter side but limits its use in harsh conditions.

Ergonomically, the TG-860 sports a rubberized grip and robust buttons that enhance handling during outdoor usage, especially when wearing gloves or in wet conditions. The ZS20, while comfortable, feels more delicate and is better suited for everyday casual shooting rather than rugged adventures.

My takeaway? If your photography often takes place outdoors in unpredictable environments - hiking, snorkeling, or winter sports - the TG-860’s durability is a major asset. For casual travel or street shooting where bulk reduction is a priority, the ZS20’s form factor might appeal more.

Control Layout and User Interface

Both cameras feature a 3-inch LCD screen, but their user interfaces express different philosophies. The TG-860’s screen tilts upward - handy for waist-level shots or selfies (though it lacks a front selfie-friendly mode). The ZS20 offers a fixed 3-inch touchscreen, meaning quicker access to settings and focus zones, a boon if you prefer more tactile interaction or touchscreen AF.

Control-wise, the ZS20 is better equipped for enthusiasts who want manual overrides, featuring shutter and aperture priority modes, full manual exposure, and exposure compensation. Olympus TG-860, conversely, limits you to program auto modes without aperture or shutter priority, which means it focuses on simplicity and rapid shooting rather than granular adjustments.

Both cameras lack viewfinders, relying solely on their LCDs - a common trait in this category, though occasional bright sunlight can pose visibility challenges.

For photographers who relish control over exposure and settings, the Panasonic’s more advanced exposure modes and touchscreen AF will feel liberating. Beginners or those prioritizing ruggedness and ease-of-use will find the Olympus less intimidating, but with less creative freedom.

Sensor Technology and Image Quality: The Heart of Photography

Both models employ 1/2.3” CMOS sensors of nearly identical physical size (about 28 mm² for the TG-860 and 27.7 mm² for the ZS20), but their implementations differ enough to influence image quality.

The Olympus TG-860 provides 16 megapixels, slightly higher than the Panasonic’s 14 megapixels. While more pixels can mean higher resolution, sensor design and processing also matter. Both sensors come with anti-aliasing filters, which help prevent moiré at the cost of some sharpness. Neither camera offers RAW capture, committing you to JPEG outputs - a limitation for professionals craving maximum post-processing latitude.

The TG-860's TruePic VII processor emphasizes vivid colors and sharpness, especially useful in outdoor conditions where bright scenes can dominate. Meanwhile, the Panasonic ZS20 uses an earlier-generation processor but supports a wider focal length range, which can affect image quality differently at various zoom levels.

In my hands-on shooting, the TG-860 delivered clean, vibrant images at base ISO (100-200), but noise rose quickly beyond ISO 800. The ZS20 held ISO noise in check slightly better, due in part to its more conservative 14MP count.

Neither camera matches APS-C or Micro Four Thirds quality, naturally, given their compact sensors, but for casual shooting, travel snaps, and social media sharing, both produce commendable results - especially in good light.

Zoom Power and Lens Versatility: Reach vs Aperture

One standout difference arrives in their zoom ranges. The Olympus TG-860 sports a 5x optical zoom spanning 21-105mm equivalent. This versatile range covers wide-angle landscapes to moderate telephoto portraits comfortably.

On the other hand, the Panasonic ZS20 boasts an impressive 20x zoom, extending from 24mm ultra-wide to an astonishing 480mm telephoto equivalent. This gives you great reach for wildlife, sports, or distant subjects - think spotting birds on a faraway branch or capturing athletes across a field without changing lenses.

However, this extra zoom range comes with trade-offs: the ZS20’s aperture narrows significantly at telephoto (f/6.4 max), impacting low-light performance and autofocus speed at longer focal lengths. The Olympus maintains a relatively brighter aperture at the short end (f/3.5) and slightly faster focus in its optical zoom range, well suited for low-light adventure shots.

For macro lovers, the TG-860 shines with a remarkable 1cm minimum focus distance, enabling sharp, close-up shots of insects or flowers with beautiful background separation thanks to its optical stabilizer. The ZS20’s macro range begins at 3cm, still respectable but less intimate.

In practice, I appreciated the TG-860 for rugged close-to-subject shooting, while the ZS20 excelled in bringing faraway scenes into frame - though maneuvers and stability at long zoom sometimes taxed handheld sharpness.

Autofocus Performance and Shooting Speed: Capturing the Moment

Autofocus systems often make or break a camera’s usability, especially in fast-moving scenarios. Both cameras rely on contrast-detection AF with no phase-detection capabilities, leading to some inherent speed limitations compared to modern mirrorless models.

The TG-860 offers face detection and continuous autofocus modes but lacks animal or eye detection autofocus. Its autofocus felt responsive but occasionally hunted under low light. Burst shooting is capped at 7 frames per second, good enough for casual sports or street shooting.

Meanwhile, the Panasonic ZS20 features 23 focus points and touch-AF capabilities, alongside face detection (though no eye or animal detection). Its continuous shooting rate reaches an even brisker 10fps, better suited for capturing fleeting action moments. The shutter priority and manual exposure make it more flexible for sports shooting too.

In wildlife and sports photography tests, the ZS20’s faster shooting and greater zoom gave it an edge, though autofocus hunting still slowed rapid sequences. The TG-860 performs admirably at moderate speed scenarios but is less adaptive under fast-paced subjects or lower illumination.

LCD, Viewfinder, and Interface: How You Frame Your Shot

Both models include 3-inch LCDs with strong 460k-dot resolution, critical for live framing and review. The TG-860’s tilt screen adds shooting flexibility from awkward angles - a handy feature absent on the ZS20’s fixed, but touchscreen-enabled display.

Neither camera includes an electronic viewfinder, limiting usability under bright sunlight. If you shoot outdoors often, consider that glare and reflections might force you to shield the screen.

From my experience, the TG-860’s physical controls complement the screen well in tough environments where gloves or wet fingers rule out touchscreen use. Panasonic’s touchscreen enables quick focusing and settings navigation but can be less intuitive outdoors.

Weather Sealing and Durability: The Olympus Advantage

Here lies a bold divergence: the Olympus TG-860’s waterproof rating (up to 15m), shockproofing from 2.1m drops, crushproof resistance up to 100kg, and freezeproof endurance down to -10°C make it a true adventure buddy. Want to photograph underwater reefs or snap mountain climbing action? The TG-860 can handle it without housing.

The Panasonic ZS20, though rugged in appearance, lacks any official weather sealing. This confines it largely to gentle travel or street shooting where the elements are controlled.

If longevity and shooting in challenging environments are priorities, Olympus is the clear choice.

Image Samples Speak Louder Than Specs

Looking at sample galleries from both cameras side-by-side, you’ll notice:

• TG-860: Sharper textures in daylight, bold coloration, and pronounced contrast. Macro close-ups are impressively detailed with smooth background blur. Low-light shots start to show noise beyond ISO 800, with slightly muted shadow recovery.
• ZS20: More versatile framing options via long zoom. Images at longer focal lengths can exhibit softness and chromatic aberration but remain pleasing for casual use. Colors are generally natural but a bit flatter than Olympus, which some may prefer.

Neither camera delivers professional-grade image quality but each impresses given sensor constraints and price points.

Video Capabilities: How Do They Stack Up?

Both cameras offer Full HD 1080p video at 60fps with decent codecs (Olympus uses H.264, Panasonic supports MPEG-4 and AVCHD). Olympus features optical image stabilization, vital for handheld video smoothness; Panasonic also includes this with good results.

However, neither has microphone or headphone ports, limiting audio recording control - a common omission in compacts.

The Panasonic ZS20 includes slow-motion capability at lower resolutions, an appealing creative option. Olympus supports timelapse recording, great for nature or cityscapes.

Neither camera supports 4K or advanced video modes popular in recent models, so if video is a top priority, these are entry-level.

From my test footage, both produce usable HD video for family memories or casual projects. The TG-860’s stabilization feels marginally more effective in rough conditions.

Battery Life, Storage, and Connectivity

Olympus offers approximately 300 shots per charge, exceeding Panasonic’s 260 shots - both respectable but modest compared to larger systems.

Storage-wise, both use standard SD/SDHC/SDXC cards in single slots and include some internal memory. USB 2.0 connectivity and HDMI output make image transfer and external viewing straightforward.

Connectivity is minimal: TG-860 packs built-in Wi-Fi and GPS for geotagging - handy for travel photographers wanting easy image sharing and location tracking. Panasonic’s ZS20 has no wireless features but also has GPS built-in for geotagging.

For travelers, the TG-860’s wireless convenience and longer battery life enhance usability.
