Olympus TG-810 vs Panasonic Lumix DMC-ZS100: A Hands-On Dive Into Two Distinct Compact Cameras

Choosing the right compact camera can feel like navigating a maze - with every brand touting the latest features, how do you separate marketing fluff from practical value? Today, I'm diving deep into two intriguing contenders from different eras and design philosophies: the Olympus TG-810, a rugged waterproof shooter aimed at adventurers, announced back in 2011, and the Panasonic Lumix DMC-ZS100 (also known as the TZ100), a more recent 2016 large-sensor compact geared to enthusiasts craving versatility and image quality.

At first glance, pitting a tough little adventure buddy against a more refined travel zoom might seem a bit like comparing apples to… well, waterproof oranges. But as someone who’s tested thousands of cameras, I find these contrasts fascinating because they reveal a lot about how camera technology evolves - and what actually impacts your day-to-day shooting experience.

So buckle up for a 2500-word ride where we will dissect everything from sensor performance to handling, autofocus prowess to video features, and beyond. Spoiler alert: Whether you're a rugged outdoors explorer or a thirsty travel photographer, understanding these two cameras' strengths and quirks will help you make an informed choice that really suits how you shoot.

1. Size, Build, and Handling: Toughness vs. Sophistication

I’ve always believed that a camera’s physicality communicates its soul. The Olympus TG-810 wears its ruggedness on its sleeve (or rubber body armor). It’s designed for waterlogged adventures, dust storms, freezing weather - basically, if Murphy’s Law applies, this camera laughs in the rain.

On the other end, the Panasonic ZS100 exudes a more sophisticated vibe, with a classic compact camera shape - slightly larger but more refined, offering tactile controls and a pop-up electronic viewfinder. Let's see those differences in action:

At 100x65x26 mm and weighing a mere 215 grams, the Olympus TG-810 is delightfully pocketable and feels like a sturdy companion you can toss into a backpack without hesitation. Its textured rubberized grip and sealed buttons assure you that moisture and dust won’t short-circuit your memories.

The Panasonic ZS100 is chunkier (111x65x44 mm, 312 grams), reflecting its larger, more capable sensor and longer zoom lens. The body uses more metal and quality plastics, giving it heft and a premium feel. The inclusion of an electronic viewfinder (EVF) adds thickness but delivers composure in bright daylight imaging where LCD screens falter.

Looking at the control layout, the ZS100 embraces enthusiast-style ergonomics: dedicated dials for aperture, shutter speed, and exposure compensation, plus a customizable function button and touch-sensitive screen. The Olympus TG-810 has a simpler interface, befitting its rugged use-case, with fewer buttons and no manual exposure modes.

Ergonomics takeaway: The TG-810 excels in environments where resilience matters most. If you want intuitive physical controls and manual exposure creativity, the ZS100’s design and layout will win your heart.

2. Sensor and Image Quality: The Heart of the Matter

If there's one feature that fundamentally shapes the quality of your pictures, it's the sensor. I always approach sensor comparisons armed with test charts, field shooting, and pixel-peeping to uncover the truth.

The two cameras couldn’t be more different here:

• Olympus TG-810: 1/2.3-inch CCD sensor (6.17x4.55 mm), 14 megapixels, max native ISO 1600.
• Panasonic ZS100: 1-inch MOS sensor (13.2x8.8 mm), 20 megapixels, max native ISO 12800 with boosted ISO 25600.

The TG-810 uses a small, older CCD sensor technology, which was common in compact cameras a decade ago. While it’s capable of capturing decent JPEGs in good light, dynamic range is limited, and noise levels spike quickly past ISO 400. This sensor size constrains detail resolution and low-light performance.

The ZS100’s 1-inch sensor is more than four times the surface area of the TG-810's, translating into fundamentally better image quality, especially in challenging lighting. The MOS sensor architecture combined with the Venus Engine processor delivers richer colors, wider dynamic range (as validated by DXOMark’s 12.5 EV score), and cleaner high-ISO images. The availability of RAW support is a huge bonus for enthusiasts seeking maximum post-processing latitude.

This isn’t just theory: shooting landscapes and street scenes side by side, the ZS100’s files reveal more nuanced shadows, punchier highlights, and a generally cleaner look - even handheld at night.

3. Lens Capabilities: Zoom Ranges and Apertures in Depth

From my experience, zoom versatility and optical quality are the real workhorses in compact cameras.

• Olympus TG-810 offers a 5x zoom spanning 28-140mm equivalent, with a maximum aperture range of f/3.9-5.9.
• Panasonic ZS100 sports a 10x zoom stretching 25-250mm equivalent, starting brighter at f/2.8 at the wide end and narrowing to f/5.9 at full zoom.

That means the ZS100 handles a wider variety of shooting scenarios - from wide open landscapes to close-ups of distant subjects like wildlife or architecture. The brighter wide aperture on this camera also helps in low-light environments and provides slightly creamier bokeh for portraits.

The TG-810's lens isn’t a slouch either; it’s sharp in the center, though at the telephoto end, expect softness and diffraction limiting fine detail, especially when stopped down.

Macro lovers take note: with a close-focus distance of just 3 cm, the TG-810 is surprisingly adept at near subjects in tough conditions. The ZS100 allows 5 cm macro shooting, which is respectable but not as close.

4. Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus (AF) systems can make or break your chances when capturing fleeting moments - trust me, frustration mounts quickly when AF hunts or misses in critical seconds.

The TG-810 features a contrast-detect AF system with face detection and multi-area AF. It lacks continuous AF and manual focus options, relying on a single AF mode with limited focus points. In practice, this system is effective under bright daylight situations but slows down considerably when light dims or contrast falls off - sometimes giving that agonizing lag during wildlife photography or shooting moving objects.

Contrast that with the ZS100, which has a much more advanced contrast-detect AF with 49 points, selective AF, continuous AF, and face detection. It also supports touch-to-focus on the LCD screen, providing precise and swift subject acquisition. In real-world testing, the ZS100’s continuous tracking keeps up much better with moving subjects, essential for sports or street photography.

5. Video Features: More Than Just Stills

A camera’s video capabilities have become an increasingly vital hallmark of versatility. Let’s look at what these two can offer:

• TG-810: Records HD video at 1280x720 pixels at 30 fps. Video formats include MPEG-4 and H.264. Basic video functionality with no microphone or headphone jacks, no 4K, and no advanced stabilization during video.

• ZS100: Delivers impressive 4K UHD video at 3840x2160 pixels up to 30p, plus Full HD at up to 60p. Includes Panasonic’s renowned 5-axis optical image stabilization, enabling smoother handheld footage. Also features 4K Photo mode - letting you extract 8MP still frames from video - a brilliant tool for action and street photographers. No external audio ports, so audio quality is limited to onboard mic.

If you’re serious about casual filmmaking or want to future-proof your videos, the ZS100 is the clear winner here.

6. User Interface and Display: Interaction Matters

User experience goes way beyond specs. The way a camera feels in your hands and interacts with your intentions can make the difference between a cluttered, frustrating shooting session and a seamless creative flow.

Both cameras have a 3-inch LCD screen, but with some notable differences:

The TG-810 sports a 3-inch TFT Hypercrystal III LCD with 920k-dot resolution. It’s fixed (non-articulated) but performs well outdoors thanks to hyper-crystal technology's improved brightness and clarity.

The ZS100 comes equipped with a slightly higher resolution 1040k-dot fixed LCD and, crucially, a 1166-dot electronic viewfinder - an invaluable feature in bright outdoor shooting where glare can obscure the rear screen. The ZS100 also benefits from touchscreen controls, making menu navigation and focus point selection far quicker and more intuitive.

7. Durability and Environmental Sealing: Built For Different Lives

If I had a nickel for every time a photographer lost a camera to a little rain or an unexpected tumble, I’d be on a beach somewhere sipping something overpriced. The difference in durability here is stark:

• Olympus TG-810: Waterproof to 10m (33ft), shockproof to 2.1m, freezeproof to -10°C, dustproof, and crushproof (though not rated here). This camera was purpose-built for outdoors, beach trips, mountain hikes, even pool parties.

• Panasonic ZS100: No environmental sealing - more delicate and needs careful handling in adverse weather.

For underwater or extreme adventure photographers, the Olympus comes out miles ahead, no contest.

8. Battery Life and Storage: Staying Power and Memory

No one wants a camera that dies mid-adventure or locks you to one card slot:

• TG-810: Rated for approximately 220 shots per charge using the LI-50B battery. Storage via a single SD/SDHC/SDXC slot. Modest, but typical for its size and age.

• ZS100: Rated at 300 shots per charge. Also uses one SD card slot but benefits from Panasonic’s energy-efficient design and more modern battery tech.

For all-day travel photography, the ZS100’s longer battery life is a welcome convenience.

9. Connectivity and Extra Features: Keeping Up With the Times

Connectivity is often overlooked but hugely impactful for workflows, especially if you like quickly sharing photos or GPS tagging your locations:

• Olympus TG-810: Includes built-in GPS and Eye-Fi WiFi connectivity - Eye-Fi cards are a bit archaic now, but the GPS logging is handy for adventure geotagging.

• Panasonic ZS100: Has built-in WiFi for remote control and image transfer but lacks GPS.

Here, it’s a mixed bag: Olympus has better geotagging; Panasonic offers modern wireless sharing.
