Olympus TG-870 vs Panasonic GH4: Which Camera Deserves Your Next Click?

Choosing a camera can feel like navigating a vast maze, especially when models come from vastly different categories. Today, I’m putting two very distinct cameras head-to-head: the Olympus Stylus Tough TG-870, an ultracompact rugged point-and-shoot, and the Panasonic Lumix DMC-GH4, a pro-grade mirrorless powerhouse. This deep-dive comparison will unfold their core strengths, limitations, and real-world usability from landscapes to wildlife and beyond - all based on years of hands-on testing with thousands of cameras.

If you’re wondering which is exactly “right” for you, I’ll walk you through every major photography discipline, technical aspect, and value factor. By the end, you should feel confident choosing between the portability of a tough compact and the versatile muscle of a mirrorless workhorse.

Handling & Ergonomics: Pocketable Adventurer vs Precision Rig

First, let’s get physical. The Olympus TG-870 is a compact marvel designed for durability and portability. Weighing just 221 grams and measuring 113 x 64 x 28 mm, it slips into a jacket pocket like a dream. Its rugged body is waterproof, crushproof, freezeproof, and shockproof, built specifically for rough conditions. Ideal if you want a camera that endures accidental drops, desert dust, or chilly mountain streams.

On the other hand, the Panasonic GH4 is significantly larger and heavier - 560 grams with dimensions of 133 x 93 x 84 mm. It’s an SLR-style mirrorless intended for serious enthusiasts and professionals. This means a more substantial grip, more physical controls, and a steady balance with heavier lenses. It’s weather-sealed but nowhere near the toughness level of the TG-870.

Flip them over and you’ll notice the interface difference immediately. The GH4 offers a robust selection of dials, customizable buttons, and a top LCD panel, giving tactile access to shutter speed, aperture, ISO, and more. Meanwhile, the TG-870 keeps it simple - no manual exposure modes or dedicated controls, ease-of-use prioritized over granular input.

If you favor something you can grab and go without fuss - especially outdoors - the TG-870 wins hands down. But if you want precise control and a DSLR-like experience, the GH4 is the clear pick.

Sensor Technology & Image Quality: Tiny Sensor vs Micro Four Thirds Powerhouse

Digging under the hood, both cameras feature 16-megapixel sensors, but it’s the sensor size and design that tell the real story. The TG-870 sports a 1/2.3-inch BSI-CMOS sensor, tiny at roughly 28 mm². Conversely, the GH4 houses a much larger Four Thirds sensor (17.3 x 13 mm = 224.9 mm²), nearly eight times the sensor area of the Olympus.

This size difference translates to significantly better image quality from the GH4, especially in low light and dynamic range. Panasonic complemented its sensor with the Venus Engine IX processor, delivering rich colors, high ISO performance up to ISO 25600, and excellent tonal gradation. The GH4 also supports RAW shooting, essential for professional workflows and extensive post-processing flexibility, while the TG-870 shoots only JPEGs.

Color depth and dynamic range matter greatly for landscapes and portraits - areas where the GH4 shines with its higher DxO Mark scores (which I always consult in my testing routine). You’ll preserve more detail in highlights and shadows, a godsend when shooting sunsets or shadow-rich portraits.

The TG-870’s sensor and image processor give good results for its class. It produces sharp, vibrant JPEGs and handles basic snaps well, but noise becomes visible beyond ISO 800, and the limited sensor size caps overall image quality. So, for critical image quality, GH4 has a decisive edge.

LCD Screens & Viewfinders: Articulated Touchscreen vs Tilting Basic Display

Live-view composition and image review go a long way during shoots. The GH4 offers a 3-inch fully articulating OLED touchscreen with 1036k dots, bright with excellent viewing angles and true colors. Its touchscreen support extends to tapping to focus, making manual focus pulls and menu navigation intuitive. The electronic viewfinder (EVF) is a high-res 2.36 million-dot OLED with 100% coverage and 0.67x magnification, crucial for framing under bright sunlight or tracking fast-moving subjects.

The TG-870’s 3-inch screen tilts upward about 180 degrees but lacks touchscreen functionality and is lower resolution at 921k dots. There’s no EVF or optical viewfinder, which makes shooting in bright sun a bit challenging. It’s adequate for casual snapshots but not suited for demanding composition scenarios or extended video work.

If you’re the kind who values versatility in viewing options and responsive touchscreen control during manual focusing or shooting video, GH4 is unmatched here.

Autofocus Systems & Speed: Contrast Detection vs Hybrid

Autofocus performance impacts every kind of photography, especially action and wildlife.

The TG-870 relies exclusively on contrast-detection AF with face detection. It works competently in good light and for static subjects. Continuous AF and basic tracking are available, but the system struggles to maintain sharp focus in low light or on fast-moving subjects. Also, focus points are limited and mostly centered.

By contrast, the GH4 packs a 49-point hybrid AF system with phase-detection and contrast detection, providing much faster lock speeds and far superior subject tracking. The array of focus points and selectable zones lets you tailor focus precision for complex scenes – crucial when photographing birds in flight or sports.

Does GH4 offer animal eye-detection AF? No - which is a feature found only on newer models - but its AF accuracy and speed remain excellent for its generation.

For wildlife and sports photography, I trust the GH4’s AF system implicitly; for casual travel snaps or hiking photos, the TG-870’s AF system suffices.

Lens Selection & Compatibility: Fixed Lens vs Vast Mirrorless Ecosystem

A fixed lens on the TG-870 offers convenience but no interchangeability. The built-in 21-105 mm (35mm equivalent) f/3.5-5.7 zoom covers a versatile focal range for walking-around focal lengths and decent macro down to 1 cm. Image stabilization is built-in optically, a welcome addition to compensate for hand shake when zoomed in or in low light.

The GH4 accepts Micro Four Thirds lenses, and Olympus stylus lenses can also be used with adapters if desired. This ecosystem boasts over 100 native lenses ranging from ultra-wide to super telephoto, primes, macro lenses, and professional-grade optics. Whether you want an f/1.4 portrait lens, a fast telephoto for wildlife, or stabilized zooms for video, this system has you covered.

For flexibility, GH4 is clearly advantageous. But if you want a truly pocketable, rugged camera to throw in your backpack without fussing over lenses, TG-870 shines.

Performance in Major Photography Disciplines

Portraits

The GH4’s larger sensor and access to fast prime lenses allow you to create stunning portraits with beautiful skin tones and creamy bokeh. Its face detection and selective AF points help nail sharp eyes, and shooting in RAW enables precise skin tone corrections. The TG-870 can manage casual portraits but lacks shallow depth of field, and its JPEG-only output limits post-processing latitude.

Landscapes

The GH4’s dynamic range and resolution deliver rich, detailed landscapes even under challenging light. Its weather sealing ensures you can shoot happily in mist or light rain, but remember it isn't rated fully rugged. The TG-870 is waterproof and shockproof - perfect for snorkeling or muddy trails - but its sensor limits detail and tonal depth in sweeping vistas.

Wildlife & Sports

Fast autofocus and burst rates are critical here. GH4 produces 12 fps continuous shooting with excellent tracking. It handles action in dimmer conditions thanks to higher ISO performance. The TG-870 can shoot 7 fps but with more limited AF tracking and slower focus acquisition - adequate for static wildlife but insufficient for sports or fast animals.

Street Photography

Portability and discretion matter. The TG-870 is unobtrusive, pocketable, and weatherproof, great for urban adventures and spontaneous moments. The GH4 is more visible and heavier, but its articulating screen and responsive AF can aid shooting from hip or awkward angles. For night street shots, GH4 will produce cleaner images at high ISO.
