Panasonic GH1 vs GH5: In-Depth Comparison from a Seasoned Camera Tester

Having put thousands of cameras through their paces over the last 15 years - from budget compacts to pro-level mirrorless - I’m excited to dive deep into the Panasonic Lumix DMC-GH1 and DMC-GH5. These two cameras bookend nearly a decade of rapid mirrorless evolution, from the GH1’s pioneering Micro Four Thirds tech in 2009 to the GH5’s flagship, video-focused prowess launched in 2017.

If you’re a photography enthusiast or professional hunting for a new camera, chances are you’ve come across these models - and you’re wondering how much of an upgrade the GH5 truly is over the venerable GH1. Or, if budget or vintage gear hunting is your vibe, is the GH1 still viable today? These are the real questions that matter.

I’ll cover their strengths and weaknesses across all major photography genres, dissect the guts - from sensors to ergonomics - and provide honest, practical buying advice. So let’s crack on.

First Impressions: Size, Handling, and Build Quality

Let’s start from the outside. The GH1 was Panasonic’s first entry into the Micro Four Thirds mirrorless SLR-style realm - a relatively compact camera, especially for 2009 standards. The GH5, on the other hand, is a tanky pro-level model, bigger, heavier, and more robust.

As you can see, the GH1 (124x90x45 mm, 385g) is a lightweight, pocket-friendlier option compared to the GH5’s burly 139x98x87 mm and 725 grams. The GH5’s larger grip and deeper body better accommodate larger lenses and extended use, but if discretion and travel portability are critical, the GH1 feels less like carrying clubs for your thumbs.

The GH5’s body is carefully weather-sealed - a big plus for landscape and wildlife shooters who often brave the elements. The GH1 lacks any environmental sealing, so it’s more of a gentle-weather tool.

Build-wise, the GH5’s magnesium alloy shell and heavy-duty buttons feel like something built to last decades of professional use. The GH1 uses lighter materials and plasticky parts befitting a first-gen mirrorless camera.

Control Layout and User Interface: What’s Under Your Fingers?

Ergonomics extend beyond size - how easy is it to operate the camera without diving into menus? Let’s peek at the top views.

The GH1 has a straightforward control layout: a mode dial, dedicated exposure compensation dial, and a few programmable buttons. It’s manageable but limited by its era’s technology. Your fingers will work some harder adjusting settings.

The GH5, in contrast, is a dream for those who love tactile control. Clusters of customizable dials, buttons, and a joystick for AF point selection give you granular access without taking eyes off the viewfinder. The absence of a built-in flash (present on the GH1) may annoy the casual shooter, but professionals will likely use external flashes anyway.

Additionally, the GH5 boasts a responsive touchscreen on its fully articulating 3.2-inch rear display, improving menu navigation and focus control - a feature missing in the GH1.

Sensor and Image Quality: What’s Really Captured?

This is where the rubber meets the road.

Both cameras sport Micro Four Thirds sensors, but here’s the twist: the GH1 uses a larger “Four Thirds" CMOS sensor measuring roughly 18.9x14.5 mm, while the GH5 steps down slightly to 17.3x13 mm. This reduced sensor size in the GH5 is a design choice allowing for faster readouts and advanced video features but theoretically limits light-gathering capability.

Looking at raw specs:

While the GH5 sports higher megapixels, increased max ISO, and better measured dynamic range and color depth, the GH1’s larger sensor area suggests it collected light more effectively per pixel. However, sensor tech advanced dramatically in the eight years between launches, giving the GH5 an edge in noise management and color fidelity.

This translated into real-world:

• Portraits: GH5 delivers noticeably sharper images with finer detail and better skin tone rendition, thanks to the increased resolution and improved color depth.
• Low-light shots: The GH5 wins hands down, with usable images at ISO 6400 and beyond, whereas the GH1 starts showing noise early.
• Landscape: The GH5’s extended dynamic range aids in retaining shadow and highlight detail, while GH1 needs more graduated filters or bracketing.

The GH1’s anti-aliasing filter softens fine detail but reduces moiré. The GH5 removes it, yielding sharper images but occasionally risking pattern artifacts, which is rare with good lenses.

Focusing Systems: Eye on the Subject

Depending on your genre, autofocus can make or break the shoot.

The GH1’s autofocus is modest by today’s standard: contrast detection only with selective area, no face detection, and continuous AF capped at three frames per second. This system can struggle with moving subjects or low contrast scenes.

In contrast, the GH5 builds on a dense grid of 225 contrast-detection points plus improved AI-based face and subject tracking. It occasionally rivals phase-detection systems in speed and reliability (though no phase detection itself). The 12 fps burst rate is pro-level, excellent for sports and wildlife shooters.

In practical terms:

• Portrait photography: GH5’s face and eye AF deliver confident focus even with moving subjects; GH1 requires manual or careful AF point placement.
• Wildlife and sports: GH5 tracks motion and changes in direction far better, capitalizing on high frame rates.
• Macro: Neither has specialized macro AF features, but GH5’s focus bracketing and stacking are very helpful.

Video Capabilities: The GH1’s Early Foray vs. GH5’s Powerhouse

One of the biggest leaps in GH-series cameras is video. The GH1 surprised everyone in 2009 with HD video, but the GH5 redefines the category.

The GH1 was a trailblazer, delivering decent quality 1080p video at 60fps back when DSLRs often had none. But by today’s standard, it’s limited, with no stabilization and outdated codecs.

The GH5 caters fully to advanced videographers, featuring:

• 4K recording at up to 60p (Ultra HD and DCI)
• High bit rate recording and quality codecs
• A rock-solid 5-axis in-body image stabilization, critical for handheld shooting
• Both microphone and headphone jacks for monitoring sound
• Advanced video functionality like photo modes extracted from 4K video frames

If video is even remotely important in your workflow, the GH5 is in a different league.

Screen and Viewfinder: Window to Your Creativity

Both cameras feature electronic viewfinders (EVF) and fully articulating rear screens, but improvements have been substantial.

The GH1’s 3-inch screen has a low resolution (460k dots), lacks touchscreen input, and feels quite dated. The EVF’s resolution is unspecified but noticeably grainy in real use (typical for 2009 tech).

The GH5 smartly upgrades to a 3.2-inch 1620k-dot touchscreen with intuitive UI and touch AF. This screen is bright, crisp, and better for shooting at odd angles. The GH5’s EVF is jaw-droppingly sharp, with 3,680k dots coverage at 0.76x magnification, making manual focus and composition a pleasure.

Battery Life and Storage: Power Through the Day

The GH1 packs a 320-shot battery life rating and a single SD/SDHC card slot - not surprising for its time. You'll likely want to carry spares for long sessions.

The GH5 extends endurance to 410 shots per battery (thanks to newer, more efficient processors) and includes dual UHS-II compatible SD card slots, critical for professionals who shoot long bursts or want instant backup.

Connectivity: Keeping Pace with the Modern Age

Connectivity matters for today’s workflows.

• GH1 sports no wireless connectivity, limited USB 2.0, and HDMI output.
• GH5 adds built-in Wi-Fi and Bluetooth for remote operation and file transfer, USB 3.1 Gen 1 for faster data download, and a robust HDMI port.

Wireless transfers and remote control via smartphone apps in the GH5 open up creative possibilities - yet another area where the GH1 limits modern workflows.
