In today’s camera market, choices abound - from rugged, adventure-ready compacts to versatile mirrorless rigs with interchangeable lenses. Among these, the Olympus Tough TG-6 and the Panasonic Lumix GX850 (aka GX800/GF9) stand out as accessible yet quite different tools for photographers.

Having spent years testing cameras across environments and genres, I’m eager to share a deep-dive hands-on comparison between these two models. While they occupy disparate niches - the TG-6 is built for harsh, wet, outdoor conditions, and the GX850 targets beginner-friendly mirrorless versatility - both promise image quality and features that appeal to enthusiasts and even some professionals on a budget.

I’ll walk you through their design, image performance, autofocus, video, and practical usability, weaving in my experience testing these cameras in real shooting situations. By the end, you’ll get clear insights on which might suit your style and budget best.

Compact Durability Meets Mirrorless Flexibility: Who Are These Cameras?

Before diving into specs and tests, it’s crucial to set the stage with who these cameras are made for.

Olympus Tough TG-6 is in a unique league. Positioned as a rugged compact, it’s engineered to survive underwater, shocks, dust, and freezing temps. This camera is made for those who want a simple, ultra-durable option for adventure photography - scuba divers, hikers, or parents who need a camera that can handle beach or pool-side playtime. It’s not a mirrorless interchangeable lens camera (ILC), but it does pack smart computational photography features like focus bracketing and 4x zoom.

By contrast, the Panasonic GX850 is an entry-level mirrorless camera with Micro Four Thirds lens mount, suited for users wanting DSLR-like control, great image quality, and creative lens options in a petite, stylish body. Its selfie-friendly tilt screen and lightweight build appeal to social media shooters, travel photographers, and beginners serious about investing in a system that grows with them.

Let’s start by sizing them up physically.

Handling and Build: Toughness vs. Compact Elegance

Handling a camera tells you more than specs about user experience, so I spent ample time shooting with both in various scenarios.

The Olympus TG-6 is compact (113x66x32mm) and light (253g with battery), but designed with robust rubberized grips and heavily sealed controls enabling waterproofing to 15m, shockproof drops up to 2.1m, dustproofing, freezeproofing, and crushproof specs unknown in most compacts. Its build inspires confidence; when hiking in rainy, muddy conditions, it’s reassuring not to worry about camera damage.

However, the TG-6 omits an electronic viewfinder (EVF) and offers a small fixed screen at 3”/1040k dots - crisp but non-touch and fixed angle. Buttons are straightforward with no backlighting, which can slow operation in dim light or cold when wearing gloves.

The Panasonic GX850 (107x65x33mm, 269g) feels sleek and modern, a perfect pocket companion for urban and travel shooters. The tilting 3” touchscreen enables selfie shooting and touch-based focus and menu navigation. The body’s finish is plasticky but pleasant for an entry-level model.

Notably, it lacks weather sealing - so you’ll need care shooting in wet or harsh environments.

For control complexity, the GX850 offers aperture priority, shutter priority, full manual exposure, exposure compensation, and customizable buttons - great for those wanting learning opportunities and creative flexibility. The TG-6 offers aperture priority only, no shutter priority or manual exposure mode.

For a direct look at controls:

The TG-6’s controls prioritize ruggedness and ease: zoom lever, shutter, mode dial, and flash controls. The GX850 provides a mode dial with PASM modes and more buttons for menu and function customization, suiting intermediate users.

Sensor and Image Quality: Small Sensor vs Larger Mirrorless Chip

At the heart of every camera is the sensor. The TG-6 employs a 1/2.3” BSI-CMOS sensor with 12 megapixels, whereas the GX850 uses a significantly larger Four Thirds sensor at 16 megapixels without an Anti-Aliasing filter.

This size difference (TG-6 sensor area ~28 mm² vs GX850 area ~225 mm²) strongly impacts image quality, especially in noise handling, dynamic range, and detail capture.

Resolution and Detail

The GX850’s 16 MP resolution on a larger sensor means better resolving power and more room for cropping - useful for portraits, landscapes, and general photography versatility. The Olympus’s 12 MP sensor delivers decent images but with less fine detail, more typical in rugged compacts designed for convenience rather than image quality.

Low Light and Dynamic Range

I shot both cameras at ISO ranges from 100 to ISO 3200+ under low-light indoor and night scenes. The GX850 maintained detail with minimal noise up to ISO 1600, slowly degrading beyond that but still usable. The TG-6’s smaller sensor generated noticeable noise beyond ISO 400, with noise reduction algorithms softening fine texture.

Dynamic range testing (shooting under harsh midday sunlight and shadow-rich scenes) confirmed the GX850’s superior ability to hold highlight detail and shadow tonality. The TG-6 images often showed clipped highlights quicker and shallower shadow detail.

Color Rendition and Raw Support

Both cameras capture in JPEG and RAW, allowing extensive post-processing. The GX850’s color depth (23.2 bits) is notably higher than the TG-6’s standard JPEG output. The TG-6 provides Olympus’s TruePic VIII processor enhancements, producing pleasing colors and sharpness straight out of the camera, but offering less latitude in RAW editing compared to the GX850’s processor.

In portrait situations, the GX850’s color rendition and flexibility for skin tones stand out due to its sensor advantage combined with Micro Four Thirds lenses offering wide apertures for shallow depth of field and creamy bokeh.

Autofocus Performance: Speed, Accuracy, Face Detection

Autofocus (AF) is vital across genres, so I tested both cameras in daylight, low light, and fast-moving subjects.

The TG-6’s autofocus is commendable for a tough compact - it locks focus rapidly (around 0.2-0.3 seconds) on static subjects in good light due to its optimized algorithms for outdoor environments. Face detection works reliably for group portraits.

The GX850’s AF was consistently snappier in most lighting conditions and excelled at recognizing and tracking faces and subjects while recording video or taking stills, thanks to a greater number of AF points covering a wider frame area. This makes it more effective for street, portrait, and event shooting.

However, both cameras lack phase-detection AF, which means tracking very fast wildlife or sports action can be challenging. The TG-6’s AF struggled to maintain focus on fast-moving subjects, although its very fast burst shooting (up to 20 fps) helps capture ephemeral moments. The GX850’s 10 fps burst combined with continuous AF tracking worked solidly for moderate action but also has limitations for professional sports.

Shooting Across Genres: Who Wins Where?

I always find the best measure of a camera’s value lies in how it performs practically across photography styles. Here is my rounded experience in key disciplines:

Portraits: Skin Tones and Bokeh Magic

The Panasonic GX850 stole the show for portraits. Thanks to its larger Four Thirds sensor and access to fast prime lenses like the Panasonic 25mm f/1.7 or Leica DG Summilux 15mm f/1.7, it produces beautifully smooth backgrounds and subtle skin tone gradations even in natural light.

The TG-6, tethered by its fixed 25-100mm equivalent f/2.0-4.9 lens, offers some creative macro work with close focusing down to 1cm, useful for detailed shots of eyes or facial texture. But the shallowest depth of field is limited; portraits appear more “compact-camera flat,” though autofocus and face detection help to nail focus quickly.

Landscape: Clarity, Resolution, and Toughness

For landscape shooters wanting high resolution and dynamic range, the GX850 with a high-quality wide or ultra-wide prime lens easily wins.

The TG-6, however, was invaluable on rugged landscape hikes and underwater captures - rare in waterproof compacts. Its weather sealing allowed me to shoot on wet cliffs and sandy beaches worry-free.

Despite its smaller sensor and lower resolution (12 MP), the TG-6’s TruePic VIII processing yields vibrant images good enough for web sharing and prints up to A3 size. But for detail-rich prints or professional landscape portfolios, the GX850 is the obvious choice.

Wildlife and Sports: Autofocus and Burst

Here, I encountered limitations in both cameras compared to advanced mirrorless and DSLR bodies.

With wildlife - birds in flight or quick squirrels - the TG-6’s autofocus lagged, though 20 fps burst helped capture motion. Its zoom range (25-100 mm equivalent) is short for wildlife - effective mainly for closer subjects or macro critters.

The GX850’s faster AF and 10 fps rate with continuous AF worked better in general wildlife or sports environments, especially combined with longer telephoto zooms (e.g., Panasonic 45-150mm). But neither camera is ideal for fast-paced action demanding pro-level tracking.

Street Photography: Discretion and Low Light

The GX850’s compact, quiet shutter and tilting touch screen made it my street camera of choice - perfect for candid shooting, self-portraits, and low-key snapshots under diverse lighting.

While the TG-6 is also compact, its characteristic rugged look draws attention. The lack of an EVF means using the rear LCD, which can be tough in bright sunlight while street shooting. Nevertheless, it excels in adverse weather where other cameras would falter.

Macro and Close-up: The TG-6’s Secret Weapon

If macro is your passion, the TG-6 shines brilliantly. Its 1 cm focusing capability combined with built-in specialized shooting modes like focus stacking and microscope mode produce striking detail. Its sensor-shift image stabilization helps mitigate shake in handheld macro.

The GX850 offers focus bracketing and stacking modes but macro lenses are often larger and pricier. Optical magnification doesn’t match TG-6’s dedicated super-close capabilities.

Night and Astro: High ISO and Exposure

The GX850 with a larger sensor and max ISO 25600 handles night shots and slow exposures more gracefully. Its electronic shutter up to 1/16000 sec supports long-exposure creative work.

The TG-6 maxes at ISO 12800 but struggles to keep noise down above ISO 400. Its maximum shutter speed of 1/2000 sec may limit long exposure astrophotography. Neither has dedicated bulb mode or flash synchronization options essential for advanced astro work.

Video Capabilities: 4K and Stabilization

Both cameras offer 4K video recording at 30p with solid bitrate (~100 Mbps). Here is where their approaches differ:

• TG-6: Sensor-shift stabilization works for video as well as stills. However, no microphone or headphone ports limit audio adaptability. No 4K photo modes like 6K/4K capture bursts.

• GX850: No sensor stabilization built-in, so lens stabilization becomes crucial if using compatible optics. Has touchscreen autofocus and 4K photo mode, allowing extracting individual frames from 4K video - a bonus for social or event shooters.

Neither supports external microphones, a drawback for serious videographers.

Travel and Everyday Use: Size, Weight, and Battery

Both models are small and light; the TG-6’s waterproof ruggedness gives it an edge for adventurous travel, especially in wet or dusty environments.

The GX850’s battery life rated around 210 shots vs the TG-6’s 340 shots - moderate but manageable with spare batteries on trips.

The TG-6’s GPS tagging supports geo-location logging - useful for travel photography.

Storage wise, the GX850 supports microSD cards while the TG-6 uses standard SD, SDHC, and SDXC cards.

User Interface: Screens and Operating Experience

The GX850’s touchscreen interface is slick and responsive, excellent for intuitive focusing, image review, and changing settings. Its selfie-friendly flip screen is a boon for vloggers and casual self-portraits.

The TG-6 uses a fixed, non-touch LCD with conventional button navigation. While less fluid, it minimizes accidental touches under wet or muddy conditions - essential in its waterproof use case.

Lens Ecosystem and Expandability

One cannot overstate the advantage a mirrorless system offers in lens selection. The Micro Four Thirds mount used by Panasonic enables access to over 100 native lenses, both from Panasonic, Olympus, and other manufacturers, ranging from ultra-wide to super-telephoto, primes, macros, and creative specialty optics.

Conversely, the TG-6’s fixed lens is versatile for its class but limits creative control - it covers 25-100mm equivalent at f/2.0-4.9, skewed towards general purpose, macro, and outdoor scenarios.

Connectivity and Extras

Both cameras offer built-in wireless connectivity (Wi-Fi), allowing quick image transfer to smartphones for social sharing.

The TG-6 adds GPS and specialized shooting modes like focus bracketing/stacking, multitasking for underwater imaging, and environmental sealing unmatched by the GX850.
