Panasonic FZ80 vs. GH3: Which Camera Wins Your Photography Dollar?

Having logged thousands of hours behind the viewfinders of digital cameras spanning entry-level compacts to pro-grade mirrorless beasts, I’ve come to appreciate how a camera’s specs on paper rarely tell the whole story. The 2017 Panasonic Lumix DMC-FZ80 and the 2012 Panasonic GH3 are two very different beasts, yet they sometimes target overlapping users: enthusiasts who want decent versatility without breaking the bank. Today, I’m taking these two Panasonics head-to-head in a comprehensive hands-on comparison, where I’ll dig deep into the tech, real-world usability, and value - so you know exactly how each camera performs for your style of photography.

Let’s get right into it.

Getting to Know the Contenders: The FZ80 and the GH3

Before we dive under the hood, here’s a quick refresher on these two cameras. The Panasonic Lumix DMC-FZ80, also known in some regions as the FZ82, is a classic superzoom bridge camera. Released in early 2017, it packs a hefty 60x (20-1200mm equivalent) zoom lens, wrapped around a small 1/2.3” sensor.

On the other side of the ring, the Panasonic Lumix DMC-GH3 comes from Panasonic’s illustrious Micro Four Thirds mirrorless lineup. Announced back in 2012, its claim to fame has been advanced video features for the time, sturdy build, and a more traditional interchangeable lens system based on the Micro Four Thirds mount (with 100+ lenses available).

The following image highlights their differences in physical size and ergonomics (and yes, they feel quite different in hand):

As you can see, the FZ80 has a slightly bulkier bridge-style build designed to entice superzoom fans, while the GH3 is sleeker and lighter, designed to cater to photographers who value lens interchangeability and durability.

Sensor Size and Image Quality: The Core of the Matter

From a sensor perspective, the GH3’s Four Thirds 17.3 x 13mm sensor dwarfs the tiny 1/2.3" (6.17 x 4.55mm) sensor inside the FZ80. To put those numbers in perspective, the GH3’s sensor area is roughly 8 times larger than that in the FZ80 - which translates directly into better low-light performance, dynamic range, and overall image quality potential.

Here’s a direct visualization of their sensor sizes alongside key image quality indicators:

During my lab testing, the GH3 yielded richer colors with deeper contrast and significantly better noise management at higher ISOs. Its native ISO range tops out at 12,800 (albeit with some image degradation), compared to the FZ80’s maximum native ISO of just 3200.

In practical terms:

• Portraits shot with the GH3 come alive with vibrant skin tones and cleaner details in shadows.
• Landscape shots benefit from the wider dynamic range, capturing subtleties in bright skies and dark terrain.
• The FZ80 struggled beyond ISO 800, showing notable noise that softened details.

If image quality (particularly in challenging lighting) is a priority, the GH3’s sensor wins decisively.

Autofocus Systems: Getting That Sharp Focus Fast and Reliably

Autofocus can make or break a shoot, especially if you’re shooting wildlife or sports.

The FZ80 employs a contrast-detection AF system with 49 focus points, featuring face and eye detection - a nice bonus for portraits and casual shooting. It also supports post-focus, focus bracketing, and focus stacking, which is impressive for its class.

The GH3 comes with a contrast-detection AF system too, but only 23 focus points (less than half of FZ80’s). Oddly enough, that didn’t hurt its performance much due to the more sophisticated AF algorithms in a mirrorless design with interchangeable lenses. However, the GH3 lacks advanced eye or animal eye AF found in newer models.

Autofocus speed and tracking? Here’s what I found in real-world shooting:

• The FZ80’s AF is adequate for still subjects and casual wildlife snaps but struggles tracking fast-moving objects, especially at full zoom.
• The GH3 acquitted itself well in sports and street photography, locking focus swiftly even in dimmer conditions - ideal for content creators needing reliable autofocus.

Ergonomics and User Interface: Controls That Work for You

For many photographers, how a camera feels and interfaces can make or break a purchase.

Check out the control layouts side by side:

The GH3 sports a more traditional DSLR-style top plate with dedicated exposure compensation, shutter speed, ISO dials, and customizable buttons - a dream for controls enthusiasts and pros who want direct access to key settings. The fully articulating OLED touchscreen also adds versatility for tricky angles.

In contrast, the FZ80 relies on a more minimalist control interface, with some menus accessed via touchscreen. It lacks an articulating screen and sports fewer physical buttons (which helps keep costs down).

Takeaways:

• The GH3’s extensive physical controls and robust menu system are more suited for photographers who want quick manual overrides on the fly.
• The FZ80’s compacte, intuitive (if more limited) interface will please casual shooters who prefer straightforward operation.

Here’s how the LCD screens stack up:

While the FZ80 offers a higher resolution screen (1.04 million dots) with touch capabilities, it’s fixed and not particularly bright. The GH3’s fully articulating OLED has a slightly lower resolution (614k), but the color fidelity and viewing angles are better, making it more flexible in live shooting scenarios.

Lens Ecosystem and Flexibility: Fixed Zoom vs. Interchangeables

One of the major dividing lines is that the FZ80 has a fixed 60x zoom lens (20-1200mm equivalent, f/2.8-5.9) - a versatile all-in-one solution superb for travel and wildlife on a budget. If you despise swapping lenses but want reach, this is your playground.

The GH3’s Micro Four Thirds mount opens a vast universe with over a hundred native lenses, including fast primes, ultra-wide angles, dedicated macro lenses, and stabilized zooms. This lets you build a tailored kit based on your specialty - something no bridge camera can compete with.

For:

• Portrait work, swap in a fast f/1.4 or f/1.8 prime for luscious bokeh.
• Macro shooters get true close-up lenses with superior sharpness.
• Landscapes shine with wide angles that the FZ80’s fixed lens just can’t match.

The choice essentially boils down to:

• Fixed-lens convenience at super telephoto reach with the FZ80, versus
• Creative freedom and superior optics with the GH3’s interchangeable lens system.

Burst Shooting and Sports Photography: Catching the Action

If you’re chasing action shots or wildlife, frame rate and autofocus tracking become critical.

The FZ80 shoots at a respectable 10 fps, which is fast for a superzoom bridge camera. However, the buffer fills quickly, and focus tracking is somewhat laggy.

The GH3 boasts an impressive 20 fps burst mode, delivering smoother tracking and longer bursts before the buffer fills - a feature that still stands up well by today’s standards.

Coupled with the GH3’s better low-light AF and faster shutter speeds (max 1/4000s vs. FZ80’s 1/2000s), the GH3 feels far better suited for sports, birds, or kids in motion.

If high-speed continuous shooting is key, I’d lean towards the GH3.

Video Capabilities: Which Video Shooter Fits Your Needs?

Although both offer video, their intended use cases diverge.

The FZ80 delivers 4K UHD video at 30p, and 1080p at 60p, encoded in MP4 with AAC audio. It includes 4K photo modes for extracting high-res frames from videos - great for videographers wanting versatility in a compact package.

The GH3, despite its age, was a pioneer in advanced video: It records full HD (1080p) at multiple frame rates (up to 60p), supports AVCHD, MPEG-4, and H.264 codecs, and offers microphone and headphone jacks for pro audio monitoring - very rare for cameras in its price bracket.

The GH3’s video controls are more comprehensive with focus peaking and zebras for exposure, making it a favorite among independent filmmakers and YouTubers on a budget.

If you’re primarily shooting 4K casual video, the FZ80 is convenient and easy. But if you need full HD pro video with external audio options, the GH3 remains a strong choice even today.

Build Quality and Weather Sealing: Ready for the Elements?

Here’s a critical point for outdoor photographers.

The GH3 brings weather sealing - dust and splash resistant magnesium alloy body - built to withstand rugged shooting environments. For landscape, wildlife, or travel photographers who endure variable weather, this adds tremendous peace of mind.

The lightweight FZ80 is plastic-bodied and does not offer weather sealing; it’s better suited for fair weather and casual uses.

For adventurous shooters who want a robust, reliable camera to go anywhere, the GH3 is the clear winner.

Battery Life, Storage, and Connectivity: Practical Daily Use

Battery life is often overlooked but can slow down shoots quickly.

The FZ80’s battery delivers around 330 shots per charge, while the GH3 impresses with a longer 540-shot battery life. For extended fieldwork or travel, that’s a significant advantage.

Both cameras use a single SD card slot supporting SD/SDHC/SDXC cards. Neither supports UHS-II speeds, but they are fine for most users.

On connectivity, both provide built-in Wi-Fi for wireless image transfer, but no Bluetooth or NFC. The GH3’s USB 2.0 port is notably slower than current standards but sufficient for tethered shooting in the studio.
