Nikon Z30 vs Panasonic GH5: An Expert Face-Off for the Discerning Photographer

When considering a mirrorless camera purchase, enthusiasts and professionals alike want to understand not just the specs on paper, but how those translate into real-world performance. After spending dozens of hours testing both the Nikon Z30 and the Panasonic Lumix GH5 across a variety of photographic disciplines, I’m ready to break down the strengths, weaknesses, and usability of each. These cameras target very different segments within the mirrorless ecosystem, making this an enlightening comparison that serves up practical advice for users with distinct needs and budgets.

First Impressions: Size, Feel, and Handling

At first glance, the Nikon Z30 and Panasonic GH5 share an SLR-style mirrorless body design but diverge sharply in size and heft.

• Nikon Z30: Designed as an entry-level mirrorless camera, the Z30 is compact and lightweight, weighing just 405 grams with dimensions of 128x74x60 mm. This makes it perfect for on-the-go shooting, travel, and casual daily use where portability counts.

• Panasonic GH5: The GH5 tips the scales at a substantial 725 grams and is larger at 139x98x87 mm. This pro-oriented body feels robust in hand, emphasizing stability, a comprehensive grip, and serious durability. Its build suggests readiness for demanding professional assignments.

Handling-wise, the GH5’s larger size allows for a sprawling control layout with dedicated buttons and dials for nearly every function, while the Z30 favors minimalism and touchscreen interaction to streamline novice workflows - a reflection of their intended users.

Control Layout and User Interface: Touchscreen vs Tactile Buttons

Looking down at their control tops, the GH5 impresses with an array of physical buttons, mode dials, and a dedicated ISO selector - catering to photographers who want immediate tactile access to settings without diving into menus. The Z30’s top plate shows a streamlined approach, with limited physical controls complemented heavily by its fully articulated touchscreen. This serves selfie lovers well and beginners who benefit from touch-based navigation, but pros may find it lacking for rapid manual adjustments during dynamic shoots.

The GH5 also offers a high-resolution electronic viewfinder (EVF), featuring 3.68 million dots and 100% eye-level coverage, a critical advantage for daylight or fast-action shooting. The Z30 notably lacks any built-in EVF, relying solely on its LCD screen for composing shots, which may hamper usability in bright environments or for critical manual focusing.

Display Technology: Articulated Screens Designed with the User in Mind

Both cameras boast fully articulating LCD screens - a boon for vloggers, macro shooters, and those who demand flexible framing. The Nikon’s 3.0-inch, 1.04 million-dot display is crisp and bright, optimized for selfie mode with touch-to-focus and intuitive menu navigation. However, its lower resolution doesn’t quite match the Panasonic GH5’s sharper 3.2-inch, 1.62 million-dot screen, which delivers superior detail and color fidelity crucial for tasks like tethered studio work or outdoor daylight shooting.

If you’re someone who constantly relies on the LCD for both shooting and reviewing images/videos on the go, the GH5’s screen will feel more refined and easier on the eyes during extended use.

Sensor Size and Image Quality: APS-C vs Four Thirds

Diving under the hood reveals one of the most significant distinctions: sensor size. The Nikon Z30 features a 21-megapixel APS-C CMOS sensor measuring 23.5 x 15.7 mm, whereas the Panasonic GH5 utilizes a 20-megapixel Four Thirds sensor sized 17.3 x 13 mm.

The larger APS-C sensor in the Z30 controls a bigger surface area for light gathering by nearly 64%, directly translating to superior noise performance and dynamic range in many scenarios. In practice, this manifests as cleaner high ISO shots, richer tonal gradation for landscapes, and smoother skin tones in portraiture.

By contrast, the GH5’s sensor offers the benefits typical of Micro Four Thirds: a more compact lens ecosystem, faster autofocus on certain lenses, and tighter depth of field when paired with equivalent focal lengths. While its sensor area is smaller, this camera compensates with a sophisticated image processor and powerful image stabilization - critical when shooting handheld.

The GH5’s DxOMark ratings (overall 77, color depth 23.9 bits, dynamic range 13 EV, low-light ISO 807) indicate strong performance for a Four Thirds sensor that remains competitive with some APS-C models in practical output, especially when coupled with in-body stabilization.

Autofocus Systems: Speed, Precision, and Tracking Prowess

Both cameras advance strong autofocus (AF) systems but approach them differently.

• The Z30 sports Nikon’s hybrid AF, combining phase-detection with contrast detection spread over 209 focus points across the frame. It features eye and animal eye detection - great for precise portrait and pet photography. Its ability to reliably track moving subjects at 11 frames per second is excellent for an entry-level model.

• The GH5 relies exclusively on contrast-detection AF, which is less adept at fast tracking but benefits from a dense 225 AF points. It does not support animal eye AF, requiring greater user skill for subjects such as wildlife or pets. Its 12 fps burst rate is slightly faster and paired with a responsive Venus Engine processor.

In practical shooting tests, I found the Z30’s AF quicker to lock onto eyes and maintain focus under varied lighting, particularly outdoors and in portrait sessions. The GH5’s AF, while consistent, can occasionally lag in continuous tracking compared to modern phase-detection systems, especially with fast-moving subjects.

Image Stabilization and Burst Shooting: Holding Steady and Capturing the Moment

A vital difference lies in stabilization:

• The GH5 features 5-axis sensor-shift (in-body image stabilization or IBIS) that works hand-in-hand with lens stabilization for shake reduction, invaluable for handheld shooting in low light, video, and macro photography.

• The Z30 lacks any form of IBIS, compelling shooters to rely on stabilized lenses or tripods, which fits its overall position as a compact, cost-conscious powerhouse.

Burst shooting capabilities of both are impressive, with the Z30 hitting 11 fps and the GH5 12 fps. However, buffer depths and processing speeds favor the GH5, allowing prolonged burst sequences at high resolution - a plus for wildlife and sports photographers.

Build Quality and Weather Sealing: Durability Meets Fieldwork Needs

Both cameras claim environmental sealing, yet there are nuances:

• The GH5’s magnesium alloy chassis excels under professional use, with extensive sealing against dust and moisture - ideal for challenging conditions such as harsh landscapes or sports events.

• The Zebra-colored Nikon Z30 offers some sealing but lacks the reinforced build and feels less robust overall. This doesn’t disqualify it for outdoor use but suggests caution in severe weather or demanding scenarios.

Lens Ecosystem and Compatibility: Choosing Your Glass

Here we encounter another stark contrast:

• Nikon Z30 mounts Z-series lenses tailored for APS-C and full-frame Z-mount bodies. As of today, Nikon offers approximately 35 Z lenses, with emphasis on high-quality primes and zooms covering everyday and specialized focal needs. The lens range is expanding rapidly, making the Z system increasingly versatile.

• Panasonic GH5’s Micro Four Thirds mount boasts a sprawling ecosystem of over 107 lenses from Panasonic, Olympus (OM System), and third parties such as Sigma and Tamron. This spectrum spans everything from ultra-wide fisheye to super-telephoto and macro options, plus a wealth of affordable vintage glass with adaptors.

The GH5 thus wins hands-down for sheer lens variety and compatibility, which is especially attractive for photographers wanting specialized glass or budget options. Meanwhile, the Z30 benefits from newer lens designs with modern optics optimized for mirrorless performance and sharper wide-open apertures.

Video Capabilities: A Game-Changer for Hybrid Shooters
