Nikon Z5 vs Sony RX1R II: A Tale of Two Full Frame Innovators

Choosing between two stellar full-frame cameras can feel like picking between wildly different yet equally delicious desserts - each with its own distinct flavors and textures. Nikon’s Z5 and Sony’s RX1R II might both carry the full-frame badge, but they cater to very different appetites and photographic philosophies. Having spent weeks pushing both cameras through thousands of frames across varied shooting conditions, I’m excited to unpack this comparison into something digestible, honest, and practical for you, whether you’re a seasoned pro or an enthusiastic hobbyist.

Let’s start by laying out the battlefield: Nikon’s Z5 is a full-frame advanced mirrorless camera launched in mid-2020, aimed primarily at enthusiasts seeking versatility without breaking the bank. Meanwhile, Sony’s RX1R II, released in 2015, is a pioneering large sensor compact designed for maximum image quality in an ultra-portable package. They occupy distinct niches, yet the temptation to pit them against each other arises naturally due to their full-frame sensors and the prestige associated with that format.

Size and Handling: DSLR-Style Robustness vs Pocketable Elegance

The Nikon Z5, with its SLR-style mirrorless body measuring 134x101x70mm and weighing 675g (with battery), feels substantial in hand. It offers a reassuring grip and a well-thought-out button layout that encourages confident single-handed operation - a trait that many of my sports and wildlife colleagues appreciate when tracking fast-paced subjects. The weather sealing - an oft-underrated feature - provides peace of mind for field shooters who dare to brave the elements.

By contrast, the Sony RX1R II is a marvel of compact engineering. Its 113x65x72mm size and 507g weight render it virtually invisible in a jacket pocket or purse, encouraging a reportage or street photographer’s stealthy intimacy with subjects. However, this diminutive size comes with trade-offs in handling comfort, especially for those with larger hands or when paired with the fixed 35mm f/2 lens - which, by the way, is a system unto itself.

While the Z5 affords the option to swap lenses, adding versatility, the RX1R II deliberately strips complexity to focus all attention on image quality and portability. Ergonomics is, therefore, a tale of intended use - the Z5 is designed for extended shoots and heavier workloads, while the RX1R II banks on subtlety and ease of carry.

Design and Controls: Intuitive Interface vs Minimalist Precision

Handling extends to controls, and here the Z5’s mirrorless heritage is clear. It sports a pronounced mode dial, twin command dials, and a fully articulating 3.2-inch touchscreen LCD with 1,040k-dot resolution. This combination offers flexibility in touch or physical control preference, critical when working quickly in dynamic environments like events or wildlife. The EVF boasts a sharp 3,690k-dot resolution and covers 100% of the frame with a magnification factor of 0.8x - an immediate confidence boost when framing.

The Sony RX1R II, in contrast, offers a more minimalist top-plate with fewer dedicated dials, relying on its fixed focal length lens and fixed-button setup. The tilting 3-inch LCD does its job with 1,229k dots, but lacks touchscreen functionality, which was a surprise given its age and Sony’s penchant for touchscreen in their other models. Its EVF resolution at 2,359k dots is decent though not top-tier, paired with 0.74x magnification and full frame coverage.

For photographers who prefer intuitive tactile interactions and speedy access to custom functions, Nikon’s more comprehensive control layout feels like a boon. The RX1R II appeals to those who embrace simplicity - rewarding mastery with less interface clutter but demanding more manual input finesse.

Sensor Technology and Image Quality: Resolution, Dynamic Range, and Color Fidelity

At the heart of both cameras lies a full-frame sensor - the image-making powerhouse - but their architectures and generations differ significantly.

The Z5 employs a 24.3-megapixel CMOS sensor paired with Nikon’s Expeed 6 processor. While its resolution isn't revolutionary by today’s standards, its sensor design incorporates a 5-axis in-body image stabilization (IBIS) system, a remarkable feature for handheld shooting versatility. Its native ISO range spans 100 to 51,200 (expandable down to 50 and up to 102,400), providing ample flexibility for challenging light.

On the other side, the RX1R II packs a whopping 42.4-megapixel BSI-CMOS sensor - back-illuminated for improved light-gathering efficiency - with no anti-aliasing filter to maximize detail sharpness. Thanks to sophisticated Sony BIONZ X processing, this results in exceptional spatial resolution (7952x5304 max pixels) and impressive DXOMark scores: an overall score of 97, color depth of 25.8 bits, dynamic range of 13.9 EV stops, and low-light ISO performance pushing to 3204 ISO equivalent.

Real-world testing affirmed these numbers. The RX1R II delivers outstanding detail retention - perfect for landscape photographers craving texture in foliage or architectural lines - with minimal noise up to ISO 3200. The Z5, while slightly behind in resolution and dynamic range, surprises with clean files and naturally pleasing color rendition especially in daylight. Nikon’s sensor and processor combination provides a balanced palette rather than razor-sharp clinical results - flattering for skin tones in portraits and versatile for general use.

Both cameras shoot in RAW format, giving serious photographers latitude for advanced post-processing. However, the RX1R II’s higher resolution files demand more storage and processing power - an important consideration when working on bulk projects or on less powerful machines.

Autofocus Systems: Speed, Precision, and Tracking Capabilities

Autofocus is where the Z5’s more recent technology shines. It boasts 273 focus points with hybrid phase and contrast detection, enhanced by subject recognition including eye and animal detection AF. This combination yields a responsive and reliable autofocus performance across genres from portraits to wildlife to sports.

During field tests in a wildlife reserve, the Z5 successfully tracked birds in flight and fast-moving mammals, though the 4.5 fps continuous shooting rate is modest. For sports shooting, I found it serviceable but not designed to compete with top-tier action cameras that exceed 10 fps.

In stark contrast, the Sony RX1R II sports 25 focus points relying on phase and contrast detection but without continuous AF or tracking AF in burst mode. It is optimized for accuracy over speed and works best with deliberate, static subjects. This renders it less ideal for wildlife and sports - but a delight for street photography and landscapes where precise focusing overrides rapid acquisition.

The RX1R II's focus macro capability extends to 14cm, enabling intimate close-ups - though stabilization is absent, requiring a steady hand or tripod. Nikon’s 5-axis IBIS on the Z5 certainly takes the edge off minor shakes, broadening compositional handicaps.

Lens Ecosystem and Fixed vs Interchangeable Optics

Lens compatibility can make or break your photographic ambitions.

The Nikon Z5 uses the Nikon Z mount, offering access to a robust range of 15 native Z-mount lenses, including excellent primes and telephotos, alongside the ability to mount DSLR lenses via FTZ adapters - a boon for Nikon veterans. This flexibility spans from ultra-wide landscapes, macro, portraits, sports telephotos, to weather-sealed pro-grade zooms, matching most professional and enthusiast needs.

The Sony RX1R II takes a radically different approach: a fixed 35mm f/2 Zeiss Sonnar lens that's exceptionally well-crafted optically but challenging for photographers who crave versatility. This lens is the RX1R II’s signature strength and limitation rolled into one. If you’re a 35mm lover - a classic street or documentary focal length - you’ll revel in its sharpness, minimal distortion, and luminous f/2 aperture. However, if you want to zoom, switch to long lenses, or shoot macros with extreme distance, you’ll find the RX1R II restrictive.

This begs the question: which is more “flexible”? Nikon’s Z5 wins hands down for those who want one system to do it all; Sony’s RX1R II is for purists who appreciate focus, image quality, and pocketability at the cost of specialization.

Build Quality, Weather Sealing, and Durability

If you’ve learned anything from field experience, it’s that ruggedness matters. The Z5 enjoys weather sealing, affording some protection against dust and splashes, making it a sturdier companion outdoors, especially in demanding conditions. Its magnesium alloy frame and robust plastics give it a palpable sense of durability.

The RX1R II’s compact body sacrifices environmental sealing for its diminutive size. Its magnesium alloy chassis is well-built for a compact camera, but you don’t want to be caught shooting in rain or dusty environments without extreme caution.

So, if you’re an adventurer or landscape shooter often exposed to the elements, Nikon’s Z5 better aligns with reliability on-location.

LCD and Viewfinder Experience: Articulations, Resolution, and Touch Interactions

Both cameras offer tilting LCD screens but vary in usability.

The Z5’s 3.2-inch 1,040k-dot touchscreen LCD is a highlight for users who like touch-to-focus, menu navigation, and framing from odd angles - invaluable for macro and low-angle landscape work. The inclusion of a high-res EVF with 3,690k dots and 0.8x magnification feels immersive, pushing the mirrorless experience closer to optical viewfinders’ satisfaction.

The Sony RX1R II’s 3-inch, higher resolution 1,229k-dot LCD tilts but does not support touch input, which may slow menu navigation and focus point selection. Its EVF, while lower in resolution and magnification (2,359k dots, 0.74x), is still sharp for its class, providing a helpful framing aid despite the camera’s compact size.

For live view photographers or video shooters, the absence of touch on the Sony could be irksome, while those who prefer buttons will appreciate the RX1R II’s straightforward interface.

Burst Shooting, Buffer, and Memory Card Support

The Z5's continuous shooting peaks at a modest 4.5 fps, with continuous AF and tracking. This rate is sufficient for general-purpose use, portraits, casual wildlife, and street photography, but may frustrate sports photographers chasing split-second highlights.

The RX1R II excels in image quality but limits burst shooting to 5 fps with AF and tracking disabled. Realistically, this camera is for methodical shooting rather than action bursts.

Regarding storage, the Z5 offers dual UHS-II SD card slots, important for professionals needing backup and flexible workflows. Sony RX1R II has a single card slot supporting SD and Memory Stick Pro Duo cards - limiting but workable for most casual and enthusiast workflows.

Battery Life and Connectivity

The Nikon Z5 impresses with a rated battery life of approximately 470 shots per charge (CIPA standard), making it a reliable companion on longer trips or busy days. The USB-C port enables in-camera charging, a modern convenience, and built-in Wi-Fi plus Bluetooth facilitate swift image transfers and remote control.

The Sony RX1R II lags somewhat with a rated 220 shots per charge and older USB 2.0 connectivity. It supports Wi-Fi and NFC for wireless transfer but lacks Bluetooth, which makes seamless smartphone pairing a little clunkier.

For travel photographers or those who dislike frequent battery swaps, the Z5's endurance and connectivity edge out the RX1R II hands down.

Video Features: 4K on the Nikon, Full HD on the Sony

Neither camera aims primarily at videography, but video capabilities can be a dealmaker for hybrid shooters.

The Nikon Z5 records 4K UHD (3840x2160) up to 30p with full-sensor readout, albeit with a crop, and offers Full HD up to 60p. The presence of microphone and headphone jacks, plus in-body stabilization, make it a decent tool for casual video work or vlogging.

The Sony RX1R II is limited to Full HD 1080p recording up to 60p and 120fps in 720p for slow motion. It has a microphone port but no headphone jack or IBIS, restricting it for serious video applications.

In this arena, Nikon’s Z5 clearly offers a more flexible and modern video workflow.
