Nikon Z6 II vs Olympus PEN-F: A Hands-On Duel of Mirrorless Excellence

Choosing a mirrorless camera can sometimes feel like navigating a minefield of specs sheets, marketing promises, and earnest internet debates. Having spent over 15 years road-testing and dissecting cameras at every level - from novice compacts to high-end pro bodies - I find that the devil truly is in the details… but also in how those details shape the real-world experience behind the viewfinder. Today, let's dive deep into a face-off between two intriguing contenders from very different camps: the Nikon Z6 II, a full-frame beast aimed at pros and enthusiasts who demand versatility and muscle across photography genres, and the Olympus PEN-F, a retro-styled Micro Four Thirds camera with charm, agility, and a unique personality for advanced hobbyists who prize portability and creative control.

We’ll sift through technical specs but also temper them with what you can expect when pressing the shutter on portraits, landscapes, wildlife, or even video. By the end, you’ll have a clear sense of where each camera excels, where it compromises, and who really should consider picking one up. Let’s roll.

A First Look: Size, Feel, and Handling

Before diving into sensors and autofocus wizardry, the very first thing any photographer notices is how a camera feels in the hand - its bulk, grip comfort, and whether it’s something you want to carry around all day or just on special shoots.

The Nikon Z6 II carries a classic SLR-style mirrorless body weighing in at 705 grams and measuring 134 x 101 x 70 mm. Nikon sticks to a traditional control layout with a generous grip, robust buttons, and a palpable heft that screams “professional tool.” It’s confident in hand and weather-sealed to handle more demanding environments. Quite frankly, it feels like the camera for serious shooters who want something dependable that doesn’t skimp on ergonomics.

Contrast that with the Olympus PEN-F, which slips into the rangefinder-style mirrorless niche. It’s notably smaller and lighter - 427 grams and 125 x 72 x 37 mm - making it a joy to carry around during street walks or travels. The retro dials and minimalist yet tactile controls give it a charming personality that’s miles from the clinical pro camera aesthetic. However, its smaller size means a smaller grip, which may leave larger hands wanting more.

Though I personally appreciate the PEN-F’s portability and style for casual shooting or travel, anyone engaged in long sessions of continuous shooting or heavy lenses will likely prefer the Z6 II’s sturdier grip and durability. Especially when balanced with telephoto glass, the Z6 II feels rock solid; the PEN-F is better suited for lighter setups.

The Sensor: Full Frame vs Micro Four Thirds - The Core Difference

Sensor size is arguably the keystone between these two cameras, and it dictates much about image quality, low-light performance, and depth-of-field control.

The Nikon Z6 II proudly sports a 25.7-megapixel back-illuminated (BSI) full-frame CMOS sensor measuring 35.9 x 23.9 mm, providing a spacious sensor area of roughly 858 mm². Back-illuminated sensors enhance light gathering efficiency, crucial for cleaner high ISO shots and finer detail definition. The native ISO range stretching from 100 to a hefty 51,200 (expandable to 204,800) means the Z6 II is ready for dim theatres and night skies without flinching.

The Olympus PEN-F uses a smaller 20.4-megapixel CMOS sensor sized at 17.3 x 13 mm (Four Thirds format), about 225 mm² - roughly a quarter the sensor surface area of the Nikon. The native ISO caps at 25,600, maxing out lower than the Nikon but still respectable for its class. Thanks to improvements in sensor and processor tech, the PEN-F punches above its weight in detail and dynamic range for a Four Thirds sensor, but noise inevitably becomes more apparent at higher ISO levels.

From my laboratory testing and field experience, the Z6 II delivers smoother gradations, richer color depth, and superior low-light latitude - a combination vital for professional landscape or wedding photographers chasing fidelity and nuance.

The PEN-F, however, holds its own beautifully in good light and shines when paired with Olympus’s equally compact and famously sharp Micro Four Thirds lenses. For street photography and travel where placement and discretion trump pixel-peeping, the PEN-F offers a unique charm.

Shooting Experience: Viewfinders and Screens

While sensor size often steals the spotlight, the interface between you and the camera is also crucial. An optical or electronic viewfinder (EVF) with high resolution, responsive refresh rates, and intuitive controls can make or break your shooting flow.

The Nikon Z6 II boasts an EVF with a resolution of 3,690k dots, 100% coverage, and 0.8x magnification. It’s a bright, clear window that renders fine details and accurate colors in real time. In conjunction with its 3.2” tilting touchscreen LCD (2,100k dots), the camera offers flexibility in composing shots at various angles - very helpful for macro or video work.

Olympus’s PEN-F sports a smaller EVF at 2,360k dots and 0.62x magnification, which is adequate but noticeably less immersive when compared side-by-side with the Z6 II. Its 3.0” fully articulated screen (1,037k dots) allows flipping out for selfies or vlogging, something Nikon’s tilting screen doesn’t fully match.

The PEN-F’s touchscreen is responsive, but the Z6 II’s higher resolution screen feels crisper and more modern. Flashing back to long sessions shooting portraits or sports, the Nikon’s EVF fatigue factor is lower thanks to its bigger size and better refresh rates. But the PEN-F’s screen articulation is a winning point for street photographers or creative videographers who want creative angles and self-recording.

Autofocus and Performance: Speed, Accuracy, and Tracking

Whether you’re chasing birds in flight or working tight on faces in dim cafes, autofocus (AF) performance can be your best friend or worst foe.

The Nikon Z6 II employs a hybrid AF system combining 273 on-sensor phase-detection points with contrast detection. Nikon’s real-world optimizations lend it impressive speed and tracking accuracy, including sophisticated eye and animal eye detection that I’ve personally relied upon for sharp portraits and wildlife shots alike. Continuous shooting speeds ramp up to 14 fps with reliable buffer depth, meaning you won’t miss critical moments.

In contrast, the Olympus PEN-F relies solely on contrast-detection based AF with 81 focus points - less advanced in theory, though still competent. The lack of phase detection makes it somewhat slower and less reliable with moving subjects, especially in low contrast or low light. Maximum burst rates reach 10 fps, respectable for its sensor size but falling short in fast-action scenarios.

For example, during sports or wildlife shoots, I found the Z6 II's AF lock and tracking to be far superior - especially when tracking erratic movements in breeds like birds or athletes. The PEN-F works best with deliberate subjects or street photography where speed isn’t critical.

Lens Ecosystem and Compatibility: Choices and Flexibility

Another important facet often overlooked is the lens selection and adaptability, particularly for a serious investment.

The Nikon Z6 II benefits from the relatively new but growing Nikon Z mount system, currently boasting 15 native lenses. These range from pro-grade fast primes to high-performance telephotos. Moreover, Nikon’s FTZ adapter allows seamless use of the extensive F-mount DSLR lens lineup. This flexibility means you can tap into decades of optics built for every photographic niche imaginable.

Olympus offers over 100 lenses for its Micro Four Thirds mount - one of the most mature, diverse ecosystems available. This includes affordable primes, pro zooms, and specialty lenses designed to maximize the smaller sensor’s depth-of-field characteristics. The sheer breadth of options, often compact and affordable, make it a strong draw for enthusiasts exploring creative or travel photography.

Thanks to smaller sensors, Micro Four Thirds lenses tend to be more compact and lighter overall - boosting portability and convenience.

Build Quality & Durability: Weather Sealing and Ergonomics

When you hit the field, shoot in rain, dust, or subzero conditions, your camera’s build and weather resistance heavily impact reliability.

Nikon engineered the Z6 II with a magnesium alloy chassis and environmental sealing against dust and moisture - a hallmark of professional gear. Though not explicitly splashproof or freezeproof, it handles rough conditions far better than typical consumer models.

The Olympus PEN-F has a stylish metal body but lacks weather sealing. It’s best kept dry and protected, which suits controlled urban or studio environments but limits rugged use.

Battery Life and Storage: Ready for the Long Haul?

Nothing slows down a shoot like a dead battery or slowed transfers.

Nikon’s Z6 II uses the EN-EL15c battery offering approximately 410 shots per charge, exceeding many mirrorless peers. Dual card slots supporting the high-speed XQD or CFexpress Type B enhance data security and workflow flexibility.

Olympus relies on the BLN-1 battery with around 330 shots per charge, acceptable but leaves less margin for heavy shooting days. The PEN-F supports a single SD card slot, which is standard but more vulnerable to running out of space or accidental deletions.

Video Capabilities: Beyond Still Photography

If video is part of your creative kit, how do these performers compare?

The Nikon Z6 II shines here with 4K UHD recording up to 30p, 1080p up to 120p for slow-motion, and uncompressed HDMI output, plus microphone/headphone jacks for serious audio monitoring. Its sensor-based 5-axis image stabilization (IBIS) further smooths handheld footage.

The Olympus PEN-F sticks to Full HD 1080p max resolution - fine for casual shooting but limited for professional work. No microphone or headphone ports limit audio control, and while it offers 5-axis IBIS, the overall video package feels truncated.

Discipline-by-Discipline Breakdown: Which Camera Masters What?

To give this comparison some practical bite, here’s how I’ve found both cameras fare across a spectrum of genres - always remembering that your choice should account for personal style and needs.
