Today, we’re diving deep into two very different beasts in the digital camera world: the Panasonic Lumix FZ1000 II and the Pentax 645Z. While both carry the legacy of respected brands, they serve distinct purposes in photography.

Whether you’re a passionate hobbyist, a semi-pro looking for a versatile companion, or a professional searching for medium-format quality, this detailed comparison will equip you with the insight you need. We’ve personally evaluated these cameras across numerous shooting scenarios, tested their tech, and examined their operational nuances to bring you a comprehensive, honest assessment. Let’s get started!

First Impressions and Physical Profile: Handling and Ergonomics

Before we dig into specifications, understanding the physicality of these cameras sets the stage for user experience.

The Panasonic FZ1000 II is a large sensor superzoom bridge camera - meaning it integrates a fixed, powerful zoom lens with a relatively compact body. It weighs a modest 808g and measures 136x97x132mm. In contrast, the Pentax 645Z is a professional medium-format DSLR, considerably larger and heavier at 1550g and 156x117x123mm.

The FZ1000 II’s SLR-like design offers traditional handling but with fewer bulk and complexity; ideal if you crave something portable yet powerful. The 645Z feels more like a serious tool - you’ll notice its robust grip and weight, which reflect its pro-grade build and larger sensor size.

Ergonomically, the 645Z gains from a pentaprism optical viewfinder you’ll appreciate during long shooting sessions in bright environments. The FZ1000 II’s electronic viewfinder, while smaller, is bright and detailed but with a slight lag intrinsic to EVFs.

If travel photography or street discretion appeals, the Panasonic’s compactness and lighter weight make it friendlier for long days out. Meanwhile, the 645Z’s grip and weather-sealing support demanding outdoor use but at the cost of heft.

Controls and Interface: A Hands-On Look at Usability

How you interact with your camera impacts creativity and workflow. Let’s compare the physical controls and screens next.

• FZ1000 II

  • Fully articulated 3-inch touchscreen with 1240k-dot resolution - enabling flexible framing angles and intuitive touch focus/shutter control.
  • Back and top controls are logically grouped but limited due to the bridge camera form factor.
  • Touch AF and gesture-based interactions stand out for photo and video users seeking quick adjustments.

• Pentax 645Z

  • Larger 3.2-inch tilting screen, albeit non-touch, with 1037k-dot resolution.
  • Classic DSLR-style physical dials and buttons including a top LCD panel, which provides instant info without activating the rear screen.
  • Designed for precision manual control - excellent if manual focusing and tactile feedback matter in your workflow.

The takeaway: the Panasonic fulfills the needs of videographers and photographers who like touchscreen convenience, while the Pentax caters extensively to those who prefer hands-on, tactile feedback in a studio or rugged environment.

Sensor Technology and Image Quality

This is where these two cameras diverge significantly. Let's explore the sensor specs and what they mean for you.

The 645Z boasts a medium format sensor with over 7 times the surface area of the FZ1000 II’s 1-inch sensor. This translates directly into:

• Superior dynamic range (DxOMark scores back this up with 14.7 stops for the 645Z), allowing you to capture more highlight and shadow detail in challenging lighting.
• Exceptional color depth and tonality - especially useful for large prints and commercial work.
• Massive native ISO range to enable shooting in near-dark conditions with controlled noise.

The FZ1000 II’s smaller sensor means more noise at higher ISO, making it less ideal for low-light or high dynamic range scenes but benefiting from fast lens aperture combined with image stabilization. It also includes an anti-aliasing filter to reduce moiré at the cost of some sharpness.

If ultimate image fidelity is your goal - think fine art, high-end commercial, or landscape work - the 645Z's sensor technology shines. For everyday shooting, travel, and casual wildlife or street photography, the FZ1000 II’s sensor provides excellent balance of performance, speed, and size.

Autofocus System: Speed, Accuracy, and Reliability

Autofocus can make or break your experience, especially in dynamic scenarios like sports or wildlife.

The FZ1000 II’s autofocus relies on contrast detection, which is accurate but generally slower than phase detection. However, its touch AF and eye detection improve tracking efficiency for portraits and casual wildlife photography. The fast 12 fps burst rate is attractive for capturing fleeting moments.

The 645Z employs a hybrid autofocus system - phase detection sensors supported by contrast detection - delivering more reliable focus tracking on moving subjects, though its burst rate at 3 fps limits action shooting. Despite fewer AF points, this system performs admirably for studio portraits and medium-paced subjects.

Neither features animal eye autofocus, which is common in many modern cameras but not critical depending on your priorities. For fast wildlife or sports, the Panasonic may edge ahead given its faster burst rate and touch AF, but the 645Z excels in precise manual focus scenarios where AF is less relied upon.

Build Quality and Weather Resistance

Durability is key if you shoot outdoors or under challenging conditions.

The 645Z offers robust weather sealing, including dust and light freeze resistance (down to -10°C). This makes it well-suited for landscape, wildlife, and other outdoor work in tough climates.

The FZ1000 II is less rugged, lacking environmental sealing. It’s better kept dry and protected, so be mindful when using it in poor weather.

The Pentax’s magnesium alloy chassis lends high durability, versus the FZ1000 II’s lighter polycarbonate. This discrepancy aligns with their target markets - pro-level reliability vs. travel-friendly portability.

Lens and Zoom: Versatility at a Glance

Lens availability defines the shooting possibilities for many photographers.

• Panasonic FZ1000 II: Fixed 16x zoom lens with a range of 25-400mm equivalent at apertures from F2.8 to F4.0.
• Pentax 645Z: Compatible with the Pentax 645AF2 lens mount, offering a dedicated medium-format lens ecosystem with multiple prime and zoom lenses (at least six notable options), though none built-in.

For the FZ1000 II, the advantage is all-in-one versatility - from wide angle to telephoto, great for wildlife, travel, and everyday use without swapping lenses. The bright maximum aperture at the wide end (F2.8) also benefits low light and bokeh.

Pentax 645Z users enjoy access to professional-grade medium-format lenses, renowned for unrivaled sharpness, build quality, and large apertures suitable for portraiture and commercial photography. However, it comes at extra cost, increased bulk, and the need for lens changes.

In summary:

• Choose the FZ1000 II if you want simplicity, range, and no fuss.
• Choose the 645Z if you prioritize ultimate image quality, flexibility with pro lenses, and control over optics.

Viewfinder and LCD: Composition and Review

How you frame and review your shots is crucial, especially on longer shoots.

• Panasonic FZ1000 II offers a 2360k-dot electronic viewfinder (EVF) with 100% coverage and 0.74x magnification, plus a 3" fully articulated touchscreen.
• Pentax 645Z features a traditional optical pentaprism viewfinder with approximately 98% coverage and a 0.85x magnification, plus a 3.2" tilting, but non-touch LCD.

The EVF of the Panasonic gives you exposure simulation and live previews of settings changes - ideal for instant feedback, especially when shooting video or in challenging light.

The Pentax optical viewfinder offers a natural, lag-free, and crystal-clear view without digital artifacts or battery drain - a preferred choice for many pro photographers during extended sessions.

If you prioritize video or want a versatile LCD for creative angles, the FZ1000 II excels. For pure optical fidelity and battery savings, the 645Z wins.

Video Capabilities: From 4K to Full HD

Video nowadays is as critical as stills for many creators.

If video performance matters, the FZ1000 II is a clear winner: 4K recording, 4K photo burst modes, image stabilization, and a microphone port to improve audio quality.

The 645Z, aimed primarily at high-resolution still photographers, is limited to Full HD video and lacks stabilization. While useful for occasional video, it will not satisfy more demanding videographers.

Battery Life and Storage

The 645Z offers almost double the battery capacity and a dual card slot system appealing to professionals who demand backup and extended shooting. It lacks connectivity, so image transfer is slower without tethering.

The FZ1000 II includes modern wireless controls for remote shooting and quick image sharing, suiting vloggers and social media content creators. However, battery life is shorter, typical for smaller bridge cameras.
