Nikon Z5 vs Sigma fp L: A Hands-On Comparison of Two Unique Full-Frame Mirrorless Cameras

Selecting the right camera for your photography often boils down to matching toolsets to your shooting style, budget, and creative priorities. Today, I’m putting the Nikon Z5 and the Sigma fp L head-to-head - two full-frame mirrorless cameras that cater to advanced users but take vastly different design philosophies and feature sets to the table.

Both arrived within a year of each other, sharing the same sensor size but diverging sharply in ergonomics, autofocus capabilities, and overall approach. Having tested both extensively across diverse real-world shooting scenarios - from wildlife treks to portrait sessions and video shoots - I’m excited to share insights that go beyond spec sheets.

Let’s dive into the details, unpack the strengths and compromises, and absolutely help you figure out which might be your next camera.

First Impressions: Form Meets Function in Two Contrasting Body Designs

The very first thing you notice when placing the Nikon Z5 and Sigma fp L side-by-side is their physicality, which reflects their distinct target users.

The Nikon Z5 sports a classic SLR-style mirrorless body, ergonomically contoured with robust grip and a substantial footprint. In contrast, the Sigma fp L is astonishingly minimalist and compact, designed more like a rangefinder with an ultra-slim, boxy frame that almost invites you to think modular - add a viewfinder, cages, and grips as you please.

I appreciated the Z5’s substantial build when shooting handheld for hours: it offers comfortable “clubs for thumbs” stability and intuitive control wheels. The fp L’s smaller size is fantastic for travel or street photography where discretion is key, but you’ll sacrifice some comfort for longer shooting sessions.

The Z5 weighs in at 675 grams, nearly 60% heavier than the fp L’s featherweight 427 grams. That’s a big factor if you prioritize portability over in-hand comfort.

Layout and Handling: Who Gets the Controls Right?

When it comes to menus and dials - something a cheapskate like me pays close attention to - these two cameras present very different control philosophies.

The Nikon Z5’s SLR-style design comes with dedicated dials for ISO, shutter speed, exposure compensation, and an intuitive mode dial. Everything resides under your fingers - a real advantage for quick adjustments without menu diving.

Meanwhile, the Sigma fp L opts for a more stripped-down control surface with fewer physical buttons. It relies heavily on touchscreen controls and an on-screen menu, befitting its minimalist ethos but less efficient when shooting fast-moving subjects that require quick parameter tweaks.

For those who hate digging through layers of menus mid-shoot, Nikon’s Z5 is the clear winner. The Sigma fp L suits those willing to customize workflow around a simpler tactile experience.

Sensor and Image Quality: Counting Pixels and Capturing Details

Both the Nikon Z5 and Sigma fp L come with full-frame sensors, but their approaches to resolution and sensor tech set them apart.

The Nikon Z5 uses a 24MP CMOS sensor with back-illuminated technology and a fairly standard anti-aliasing filter to reduce moiré. It captures excellent image quality with a good balance of detail, color fidelity, and dynamic range - ideal across most genres from portraits to landscapes.

On the other hand, the Sigma fp L pushes a 61MP BSI-CMOS sensor that pushes resolution into ultra-high territory - almost four times the pixel count of the Z5. This means incredible detail capture for large prints or extensive cropping, with sharpness that few cameras in this price class offer.

However, higher megapixels often come with caveats: the fp L files are bulkier and demand more storage and processing power. Also, its max native ISO sits at 25,600 versus the Z5’s 51,200, meaning the Nikon theoretically performs better in extreme low-light conditions.

If your work emphasizes ultimate resolution - large-format prints, fine art, or commercial product photography - the fp L’s 61MP sensor is a compelling choice. For generalist shooters and event photography, Nikon’s 24MP sensor balances quality with efficiency perfectly.

The Viewfinder and LCD: Seeing Your Vision Clearly

A modern camera’s electronic viewfinder (EVF) and rear screen are your primary windows to the world. Nikon and Sigma take different approaches here.

The Nikon Z5 features a bright 3.2-inch tilting touchscreen with 1.04 million dots resolution, great for composing at odd angles and navigating menus. Plus, its EVF packs 3.69M-dot resolution and 0.8x magnification, providing crisp, lag-free framing.

Sigma fp L's 3.2-inch fixed display ups the resolution to 2.1 million dots for sharper review; however, its lack of tilting can be a drawback for low or high-angle shooting. The fp L’s EVF is optional - a significant difference. You must buy the EVF separately and clip it on, which adds to weight and cost. The EVF itself is excellent when used (3.68M dots, 0.83x magnification), but the lack of built-in VF may dissuade traditionalists or outdoor shooters who rely heavily on eye-level composing.

In brief: Nikon’s integrated, tilting EVF and touchscreen combo offers a more flexible, ready-to-go package, especially under changing lighting where eye-level framing beats relying on a fixed LCD.

Autofocus: Hunting for Critical Sharpness In the Field

Autofocus (AF) performance can make or break your shooting experience, especially in dynamic genres like wildlife or sports.

Nikon equipped the Z5 with a hybrid autofocus system combining 273 phase-detection points and contrast detection, featuring impressive eye and animal eye AF tracking. From testing, this results in reliable face and eye detection for portraits with good accuracy at continuous AF speeds up to 4.5 fps.

The Sigma fp L, meanwhile, offers contrast and phase-detection AF with 49 points - far fewer than the Z5. It lacks dedicated animal eye AF and falls short on continuous autofocus tracking during fast action. Its burst shooting rate clocks in at 10 fps, better than Nikon’s 4.5, but the autofocus may struggle to keep pace for sports or wildlife.

This translates to the Z5 being the better all-rounder for autofocus reliability. The fp L’s AF works well for static or slow-moving subjects but demands more manual focus skill or slower shooting for critical moments.

Build Quality and Weather Sealing: Ready for the Elements?

Both cameras sport weather sealing to some degree but their robustness isn’t equivalent.

Nikon’s Z5 flaunts an environmental sealing design tailored for resisting dust and moisture - great for shooting outdoor weddings, landscapes, and wildlife in challenging conditions. In my prolonged rainy-day sessions with the Z5, it demonstrated good resilience.

The Sigma fp L also offers environmental sealing but its ultra-light, modular design means fewer integrated protections for rough handling. It's decent for light favored outdoor use but I hesitate recommending it for rugged fieldwork where solid sealing is critical.

Lens Ecosystems: Picking Your Glass

The gear you put on your camera matters just as much as the body itself.

The Nikon Z5 uses the Z-mount system, which has grown significantly with 15 native lenses available - ranging from compact primes to weather-sealed zooms. Third-party support is growing, plus the Z5’s full compatibility with Nikon’s extensive F-mount DSLR lens lineup via adapter means tremendous versatility.

Sigma fp L uses the Leica L mount, which has over 40 lenses available thanks to collaborations with Leica, Panasonic, and Sigma’s own lineup. Still, the native lens selection remains narrower with fewer specialized options. Adapter use for other mounts is possible but potentially more cumbersome.

In practical terms: Nikon’s lens ecosystem better supports photographers who want a one-stop solution with consistent autofocus and image quality. The fp L suits specialty shooters who prioritize high-resolution and are willing to mix and match lenses creatively.

Battery Performance and Storage: Staying in the Game Longer

Battery life is a critical but often overlooked factor in real shooting scenarios.

The Nikon Z5 shines with an impressive 470-shot per charge rating (using the EN-EL15c battery), which kept me going through long sessions without spares in critical moments. It also supports dual UHS-II SD card slots, a prized feature for professionals needing instant backup or overflow to avoid shooting interruptions.

The Sigma fp L, however, has a more modest 240-shot battery life (BP-51 battery), about half of the Z5’s endurance - a deal breaker for event shooters or those venturing far from power sources. Storage supports a single UHS-II SD card, which means no redundant backups in-camera.

Connectivity and Wireless Features: Sharing and Remote Control

Both cameras include built-in wireless connectivity but with different feature sets. Nikon Z5 includes Wi-Fi and Bluetooth, allowing easy remote control via Nikon’s SnapBridge app and seamless image transfer.

Sigma fp L has built-in Wi-Fi but no Bluetooth, which limits connection stability and battery conservation during wireless operations. Both cameras provide USB and HDMI ports for tethering and external monitors, but the Sigma supports USB Power Delivery - handy when powering the camera via external batteries for extended shoots.

This places Nikon ahead for convenience and modern wireless workflows.

Video Capabilities: Beyond Still Images

If video matters to you, here are the real-deal scoop points.

Both cameras shoot 4K UHD up to 30fps with H.264 codec, offering solid quality for enthusiasts and semipros. The Nikon Z5’s sensor-based 5-axis image stabilization is a big plus when shooting handheld video, smoothing out shakes even with non-stabilized lenses.

The Sigma fp L lacks in-body image stabilization but supports high frame rate 1080p slow-motion up to 120fps, appealing to creative videographers. Both cameras provide microphone and headphone jacks for proper audio monitoring.

In brief: Z5 is better suited for run-and-gun shooters needing stabilized, easy sub-4K video; fp L shines with raw image detail and slow-motion potential but demands more external stabilization.
