Olympus TG-860 vs Panasonic Lumix G7: A Thorough Hands-On Camera Comparison for Enthusiasts and Pros

Choosing between the Olympus Stylus Tough TG-860 and the Panasonic Lumix DMC-G7 is less a simple format face-off and more a decision about what your photographic priorities are. On one hand, we have an ultracompact, rugged point-and-shoot built for the most demanding adventure shoots. On the other, an advanced mirrorless camera offering expandable lens options and impressive video capabilities wrapped in a classic SLR-style body. After dozens of hours testing both cameras across photography disciplines, I’m excited to take you through their capabilities, strengths, and compromises to help you make an informed choice.

First Impressions and Build Quality: Pocketability Meets Mirrorless Presence

The Olympus TG-860’s compact dimensions (110x64x28mm) and featherweight design at 224 grams scream adventure companion. It’s made for photographers who value portability and durability, not bulky gear. Its ultracompact form factor delivers impressive environmental sealing: waterproof to 15m, shockproof from 2m drops, freezeproof to -10°C, and crushproof (100kgf). This kind of ruggedness is rare and a massive advantage for travel, extreme sports, and wildlife shooters who like to push limits. You can literally toss the TG-860 in your jacket pocket without worries.

Conversely, the Panasonic G7 has a traditional mirrorless SLR-sized body measuring 125x86x77mm and weighing 410 grams - a solid but not cumbersome presence in hand. Its build is plastic but sturdy, with no weather sealing. It’s a camera for those who prioritize control over size, benefiting from an extensive lens ecosystem and more manual operation.

Handling-wise, the TG-860’s control layout is spartan by necessity - no manual exposure dials or dedicated focus mode switches, reflecting its point-and-shoot roots. Its physical buttons feel small but well placed for quick outdoor use, and the tilting 3” LCD (460K dots) is handy for varied angles.

Meanwhile, the G7 delivers classic DSLR-style ergonomics: a deep grip, plentiful physical controls, and a bright 3” fully articulating touchscreen with 1,040k dots. The EVF (2.36 million dots) offers critical framing assistance and preview fidelity that the TG-860 lacks completely.

If ergonomics and user interface are crucial to you, especially for extensive manual control or crowded field use, Panasonic holds the upper hand. The TG-860 trades direct control for waterproof portability.

Sensor and Image Quality: A Battle of Sensor Size and Digital Performance

At the heart of any camera experience lies the sensor, dictating resolution, noise performance, and dynamic range.

The Olympus TG-860 sports a tiny 1/2.3" CMOS sensor measuring just 6.17x4.55mm with an imaging area of 28.07mm², delivering 16 megapixels with an anti-alias filter. Its native ISO tops at 6400, starting from 125. These specs are typical of rugged compact cameras, optimized for versatility rather than ultimate image quality.

On the other hand, the Panasonic G7 boasts a Micro Four Thirds sensor - a huge step up at 17.3x13mm size and 224.9mm² sensor area, also offering 16MP resolution but with much larger photosites, enabling better noise control and broad dynamic range. Its expanded native ISO range goes to 25,600, facilitating superior low-light shooting.

This massive difference directly translates into image fidelity. The G7 produces cleaner images with more detail retention in shadows and highlights, excellent color depth, and sharpness - ideal for professional workflows. While Olympus’s TG-860 sensor is surprisingly capable in daylight and well-lit scenes, expect noise and softness to creep in under dim conditions.

Autofocus Systems: Speed and Accuracy in Different Settings

Autofocus responsiveness differentiates real-world usability more than many appreciate.

The Olympus TG-860 uses contrast-detection autofocus with face detection, continuous AF, and AF tracking supported. With no manual focus or dedicated AF point selection, it’s designed for simplicity. In bright light, the focus lock is fast and consistent, but in low light or complex subjects, hunting can be frustrating. Given that it’s a fixed lens system with a 21-105mm equivalent zoom, the autofocus performs adequately for casual subjects but will frustrate those wanting precision in portrait or wildlife shots.

The Panasonic G7 uses a 49-point contrast-detection AF system with continuous tracking and selective AF area choice. Notably, it supports touch-to-focus on the LCD and face detection, delivering snappy and accurate focusing performance across most scenarios. Though it lacks phase detection, the combination remains fast and reliable for moving subjects and video work alike.

For subjects like wildlife and fast sports, the G7’s AF system is far more accommodating, especially when paired with telephoto lenses, though faster DSLRs and newer mirrorless bodies do surpass it. The TG-860 is better suited to slower-paced or snapshot shooting.

Lens Ecosystem and Flexibility: Fixed Versus Interchangeable Options

This is a definitive differentiator. The Olympus TG-860 has a fixed zoom lens (21-105mm in 35mm equivalent terms) with a modest max aperture range of f/3.5-5.7. Its optical zoom is useful for casual composition but obviously limits creative control over depth of field and cannot be changed.

The Panasonic G7’s Micro Four Thirds mount - supported by over 100 lenses - offers tremendous creative freedom. From fast primes to long telephotos, macro optics, and specialized tilt-shift lenses, the G7 can accommodate nearly every photographic need. The lens choice alone makes it suitable for serious enthusiasts who want to evolve their setups.

Portrait Performance: Skin Tones, Bokeh, and Eye Detection

Portraits rely heavily on accurate skin tone reproduction and pleasing background separation.

The TG-860, thanks to its fixed zoom and smaller sensor, delivers acceptable portraits for social sharing. However, the narrow maximum apertures limit bokeh and subject isolation. The camera’s face detection helps keeping eyes and faces sharp but doesn’t include eye autofocus, which limits precision (especially with moving subjects).

The G7 shines here. Thanks to Micro Four Thirds sensor size and fast lenses available (e.g., f/1.7 primes), it can achieve beautifully shallow depth of field and creamy bokeh. Eye detection autofocus is absent, but face detection combined with precise AF area selection provides accurate focus on subjects’ eyes. Skin tones render naturally with good dynamic range, and RAW shooting allows for fine-tuned post-processing.

Landscape Photography: Megapixels, Dynamic Range, and Weather Durability

When shooting landscapes, resolution, dynamic range handling, and robustness are key.

Both cameras offer similar megapixel counts (16MP), but the G7’s larger sensor permits significantly better dynamic range, enabling recovery of shadow and highlight details in high-contrast scenes. This difference is pronounced in scenes with bright skies and dark foregrounds.

A crucial advantage of the TG-860, however, is its rugged environmental sealing. It excels in extreme outdoor conditions that would require extensive weather protection gear if you used the G7.

So if you plan to shoot landscapes in harsh conditions - mountain trips, desert dust, or underwater excursions - the toughness of the Olympus TG-860 is unmatched in this comparison.

Wildlife and Sports Photography: AF Speed, Burst, and Telephoto Capability

Neither camera is a dedicated sports or wildlife shooter, but the Panasonic G7’s interchangeable lenses tip the balance decisively.

The Olympus TG-860 offers a 7 fps burst rate, which on paper matches the G7’s 7 fps. However, the G7 supports a higher max shutter speed (1/4000s vs 1/2000s on the TG-860), useful for freezing action in bright light, and higher ISO for low light sports shooting.

Moreover, with long telephoto lenses (e.g., 100-300mm MFT optics), the G7 can deliver reach to frame distant wildlife, while the TG-860’s modest zoom is insufficient.

Autofocus tracking on the G7, aided by selectable AF points, is more dependable in capturing unpredictable movement. The TG-860 has face detection and continuous AF but can lose focus with fast subjects.

Street Photography and Discretion: Size, Noise, and Responsiveness

For street shooters, discreetness and speed are vital.

The TG-860's compactness is a huge plus here; it practically disappears in a pocket or purse. Its silent-ish shutter and no mirror make it less conspicuous. However, the limited controls can slow down reaction times when manual adjustments are needed, and the lack of an EVF makes precise composition harder in bright environments.

The G7’s larger size and shutter noise make it less stealthy, but its fast autofocus, bright EVF, and articulating touchscreen contribute to responsiveness and framing accuracy in varied shooting scenarios.

Macro Photography: Close Focus and Stabilization

Macro shooters need precise focusing capabilities and ideally image stabilization.

The TG-860 focuses as close as 1 cm in macro mode, quite impressive for a compact, and includes optical image stabilization - helpful for handholding. However, its fixed lens limits aperture control and magnification flexibility.

The Panasonic G7, while not designed specifically for macro out-of-the-box, supports a variety of macro lenses with superb optics, enhanced manual focus capabilities, and no built-in IBIS but stabilization present in some lenses compensates. Its 49-point AF also enhances manual focusing granularity.

Night and Astro Photography: ISO Performance and Exposure Modes

Low-light shooters quickly discover the limits of sensor size and ISO noise handling.

The Olympus TG-860 maxes out at ISO 6400 - usable in a pinch but generally noisy, especially for astro photography. Its shutter range caps at 4 seconds, limiting long-exposure options, though timelapse recording helps in star-trail videos.

The Panasonic G7 is a more versatile night shooter. Its sensor excels at higher ISO (up to 25,600) with cleaner results. Shutter speeds extend from 60 seconds to 1/16,000 of a second, allowing long exposures with precision. Being able to shoot in RAW and bulb mode gives astro photographers much more control.

Video Capabilities: 4K, Stabilization, and Audio

Video is increasingly critical for hybrid shooters.

The TG-860 records Full HD 1080p video at 60 fps but lacks 4K, microphone input, or advanced stabilization. Its video quality is decent for casual use and point-of-view adventures but not for filmmakers or serious vloggers.

The G7 takes the video crown effortlessly with UHD 4K up to 30 fps plus HD slow motion. It supports microphone input for external audio, has post-focus and 4K photo modes for extracting stills, and delivers richer video controls - essential for content creators and multimedia pros.

Travel Photography: Getting the Most Out of Your Bag

Depending on your travel style, one camera may serve you better.

If backpack light, rugged, and ready for unpredictable environments is key, Olympus TG-860’s waterproof, shockproof, and compact design fits perfectly. Its built-in GPS and Wi-Fi assist in travel logging and instant sharing.

If versatility, image quality, and creative control are priorities, and you don’t mind carrying a slightly larger system, the Panasonic G7’s battery life (350 shots vs 300), articulated touchscreen, and lens range are compelling traits.

Professional Use and Workflow Integration

In professional workflows, flexibility and file formats matter.

The TG-860, being a point-and-shoot, lacks RAW support - a major limitation for pros who rely on RAW for critical editing. Its non-interchangeable lens, fixed aperture range, and absence of manual exposure modes restrict manual creativity.

The G7 offers RAW capture, full manual exposure modes, and lens interchangeability - key professional features. While not weather-sealed, its support for standardized SD cards, tethering options, and robust control suite make it suitable for semi-pro and enthusiast photographers.

Connectivity, Battery, and Storage

Both cameras sport built-in Wi-Fi for image transfer and remote control, a must-have convenience in today’s workflows. However, neither supports Bluetooth or NFC.

Battery-wise, the TG-860’s Li-50B powers about 300 shots per charge - solid for a compact. The G7 edges it slightly with 350 shots per charge, helped by larger battery capacity.

Both use SD/SDHC/SDXC cards with single slots, so no advantage there.
