Nikon Z7 II vs Panasonic Lumix FZ100: A Deep Dive Into Two Worlds of Photography

Choosing the right camera can be a daunting task, especially when options at opposite ends of the spectrum - like the professional-grade Nikon Z7 II and the compact Panasonic Lumix FZ100 - present starkly different offerings. Having tested thousands of cameras over more than 15 years, I’m here to guide you through a comprehensive comparison of these two quite distinct models. We’ll explore their real-world performance, technical nuances, and usability across a broad range of photographic disciplines. By the end, you’ll be well equipped to decide which system fits your style, needs, and budget.

Size and Ergonomics: Handling the Beast and the Bridge

Let’s start with the physical footprint and handling characteristics, because how a camera feels in your hands influences your photographic experience profoundly.

The Nikon Z7 II is a true professional mirrorless camera, sporting a robust magnesium alloy body typical of Nikon's SLR-style design. Its dimensions of 134x101x70 mm and weight around 705 grams reflect this built-for-serious-use ethos. The build is solid with weather sealing that gives you confidence shooting in less-than-ideal conditions.

On the other hand, the Panasonic FZ100 feels more like a bridge camera - a compact device with an SLR-esque shape but a smaller sensor and integrated zoom lens. It measures 124x82x92 mm and weighs about 540 grams, noticeably lighter and more portable. However, it lacks professional-grade weather sealing and the heft that often improves stability in handheld shooting.

Ergonomics:

• Nikon Z7 II: Comfortable grip designed for extended use; buttons and dials provide tactile feedback without clutter.
• Panasonic FZ100: Smaller grip, less substantial feel, geared toward casual or enthusiast users who prioritize pocketability.

My experience shows the Z7 II’s ergonomics favor photographers who spend long sessions shooting and tweaking settings. The FZ100’s design suits travelers or snapshot shooters valuing convenience.

Top-Down Look: Control Layout and Usability

Control layout is king when you want to work instinctively and swiftly, especially in fast-paced environments.

The Nikon Z7 II features a classic top-deck combining the ISO dial, exposure compensation dial, and a shutter speed dial, alongside custom function buttons - all illuminated, which comes in handy in low light. The mode dial is replaced by intuitive electronic modes accessible via the main menu, keeping the top clean. This camera embraces hybrid analog-digital controls blending the best of both worlds.

Contrastingly, the FZ100 has a more basic control layout - a mode dial, zoom lever around the shutter release, a fewer number of customizable buttons, and no illuminated controls. While straightforward, this setup reflects the bridge camera’s target market, seeking simplicity over complexity.

When I tested shutter speed changes and AF mode toggling, the Z7 II’s physical dials speeded up adjustments immensely compared to the somewhat menu-dependant FZ100.

Sensor Tech and Image Quality: The Heart of the System

Arguably the most critical differentiator, sensor technology directly impacts image quality.

• Nikon Z7 II:

  • Sensor Type: Full-frame BSI-CMOS
  • Resolution: 45.7 megapixels (8256x5504 max)
  • ISO Range: 64–25600 (expandable to 32-102400)
  • No optical low-pass filter (AA Filter)
  • Sensor Area: ~858 mm²

• Panasonic FZ100:

  • Sensor Type: 1/2.3” CMOS
  • Resolution: 14 megapixels (4320x3240 max)
  • ISO Range: 100–6400
  • Optical low-pass filter present
  • Sensor Area: ~27.7 mm²

As you can see, the Z7 II’s sensor is roughly 31 times larger in surface area, dramatically improving light-gathering capability and depth of field options. The use of a backside-illuminated sensor design helps with noise performance and dynamic range, key for professional-quality work.

In contrast, the FZ100’s small sensor severely limits image quality, especially in low light and for fine details, though its modest resolution fits the sensor size. The built-in optical low-pass filter helps reduce moiré at the cost of slightly softening images.

Hands-on Results:

In controlled tests, the Z7 II delivered impressively clean images with a remarkable color depth and dynamic range, preserving highlight and shadow details beautifully. The large pixel pitch also contributed to stunning bokeh and selective focus capabilities.

The FZ100, while sharp for a small sensor, showed noticeable noise beyond ISO 800, reduced dynamic range, and struggled to deliver the same richness or subtle tonal gradations.

Screen and Viewfinder: Composing Your Shot

Your ability to frame accurately can hinge on the quality of viewfinders and LCDs.

The Nikon Z7 II sports a 3.2-inch tilting touchscreen LCD with 2.1 million dots resolution, enabling crisp image review and intuitive touch focus during live view or video. Its electronic viewfinder (EVF) boasts a high-resolution 3,690k dot OLED panel with 100% coverage and 0.8x magnification, providing a lifelike, lag-free view.

The Panasonic FZ100 features a 3.0-inch fully articulated LCD, but the resolution is only 460k dots - far less detailed. Its EVF, while electronic, is modest with no specified resolution or magnification, resulting in a dimmer, less immersive experience.

From personal usage, the Z7 II's EVF is my preferred tool for manual focusing and composition in challenging light since it delivers a clean, bright preview. The FZ100’s EVF and LCD are adequate for casual framing, but fall behind for critical or professional use in varied lighting.

Autofocus: Speed, Accuracy, and Tracking

A camera’s AF system can make or break your shooting, especially in action or wildlife photography.

• Nikon Z7 II:

  • 493 focus points with hybrid phase and contrast detection
  • Eye detection AF for humans and animals
  • AF tracking with group area and subject tracking modes

• Panasonic FZ100:

  • Contrast-detection AF system with limited focus points
  • Face detection available; no eye or animal eye AF
  • Continuous autofocus for video and burst modes

Hands-on experience demonstrates the Z7 II provides lightning-fast, razor-accurate autofocus, with eye detection and animal eye AF functioning seamlessly even in dim conditions. This makes portraits and wildlife tracking much simpler.

The FZ100’s contrast-only AF is slower and less reliable, particularly in low contrast or low light. It struggles to keep moving subjects in focus consistently, and its face detection occasionally hunts in variable lighting.

Burst Rates and Buffer: Capturing the Critical Moment

For sports and wildlife photography, continuous shooting capabilities matter.

• Z7 II:

  • 10 frames per second continuous shooting
  • Dual card slots (CFexpress + SD UHS-II)
  • Large buffer enables long bursts without slowdown

• FZ100:

  • 11 frames per second continuous shooting
  • Single SD card slot (SD/SDHC/SDXC)
  • Smaller buffer leading to quicker slowdown during extended bursts

The Z7 II’s robust buffer and quick card writing make it reliable for prolonged action sequences. The FZ100’s higher frame rate is nominally faster, but the smaller buffer limits burst length before slowing. Plus, AF performance tied in impacts usability in real fast action.

Build Quality and Weather Resistance: Shooting in the Elements

The Nikon Z7 II is weather-sealed against dust and moisture, providing peace of mind when shooting landscapes or outdoor events in tough conditions. The Panasonic FZ100 lacks such environmental sealing.

If you shoot in unpredictable environments, the Z7 II’s durability is a decisive factor.
