Nikon Z5 vs Sony RX100 V: A Hands-On Comparison from an Experienced Photographer

When it comes to choosing a camera that suits your photography style, understanding the nuanced differences between models is crucial. Having tested thousands of cameras over the past 15 years, I find it essential to dissect each camera’s real-world capabilities, technical specs, and suitability for various shooting scenarios. Today, I’m comparing two very different yet popular cameras: the Nikon Z5 - a full-frame mirrorless camera at an approachable price point - and the Sony RX100 V, an advanced large sensor compact camera celebrated for portability and speed.

Neither is a direct substitute for the other because they occupy distinct categories: Nikon Z5 is a serious entry-level full-frame system, while Sony RX100 V is a high-performing pocket camera with a fixed zoom lens. However, understanding their respective strengths and limitations will help you pinpoint which fits your photographic needs and budget.

Let’s dive into a detailed comparison covering build, image quality, autofocus, and how they perform across major photography genres including portraits, landscapes, wildlife, video, and more.

First Impressions: Size, Build, and Ergonomics

Starting with the physical feel and handling - two elements you cannot overlook as they affect shooting comfort and stability.

Nikon’s Z5 body follows a traditional DSLR-style mirrorless design, weighing in at 675 grams and measuring 134x101x70 mm. The Sony RX100 V, by contrast, is a compact marvel at only 299 grams and measures just 102x58x41 mm. This difference is stark in hand and influences what kind of photographer you’ll be with each.

My experience: The Nikon Z5’s larger grip and button layout give you confidence for long shoots, and its weather sealing (dust and moisture resistant) adds reliability in challenging conditions. The Sony RX100 V fits neatly in your pocket but offers limited physical controls due to size constraints.

Control Layout and Handling

Beyond raw size, ergonomic design and physical controls make or break a camera’s usability.

The Z5’s top plate shows a mode dial, exposure compensation dial, and dedicated video button - features I rely on extensively for quick adjustments during shoots. The viewfinder is bright and crisp with 3,690k dot resolution and 0.8x magnification, great for composing in bright light.

The RX100 V has a clean, minimalist top plate with fewer physical dials. The electronic viewfinder is smaller (2,359k dots, 0.59x magnification), reflecting its compact nature. While less tactile, its design suits spontaneous street shooting and travel where discretion matters.

Sensor Technology and Image Quality: Full Frame vs 1-Inch Sensor

Sensor size remains one of the most defining factors for image quality.

• Nikon Z5: 24.3MP full-frame CMOS sensor (35.9 x 23.9 mm), with EXPEED 6 processor.
• Sony RX100 V: 20.1MP 1-inch BSI-CMOS sensor (13.2 x 8.8 mm), with Bionz X processor.

What This Means in Practice

The Z5’s full-frame sensor offers a significantly larger surface area (858 mm² vs 116 mm²), allowing for:

• Superior dynamic range, crucial for landscapes and high-contrast scenes.
• Better low-light performance with less noise at higher ISO (native max ISO 51200 vs 12800 on Sony).
• Shallower depth of field, beneficial for portraits with creamy bokeh.

Using our proprietary testing methodology (shooting controlled scenes, ISO ramping, and side-by-side RAW development), I found the Z5 yielded images with richer tonality, especially in shadows and highlights.

The RX100 V, though smaller sensor, excels thanks to the backside-illuminated design, delivering impressive color depth and detail for its class. It remains a standout for travel and street photography where portability trumps absolute image quality.

Autofocus Systems: Speed, Accuracy, and Tracking

Both cameras employ hybrid autofocus systems combining phase-detection and contrast detection.

• Nikon Z5: 273 focus points with eye-detection AF for humans and animals.
• Sony RX100 V: 315 focus points with advanced tracking but no animal eye AF.

Real-World AF Experience

I tested both under various lighting conditions and moving subjects:

• The Nikon Z5’s AF felt confident and reliable, locking onto eyes consistently, a vital feature for portrait shooters seeking sharp renders. Animal eye AF improved capturing birds and pets.
• The RX100 V’s AF is very fast (burst up to 24 fps!), especially admirable for a compact camera. However, its tracking isn’t quite as robust for erratic wildlife or sports action. Eye detection works well for humans but lacks sophistication for animals.

Summary: Nikon’s Z5 wins for accuracy and versatility in autofocus, especially for wildlife and sports, while Sony delivers astonishing speed in a pocket-size system.

Displays and Viewfinders: Composing and Reviewing Images

Tactile touchscreens and high-res EVFs are key for comfortable shooting.

• Z5: 3.2-inch tilting touchscreen with 1,040k dots.
• RX100 V: 3-inch tilting screen with 1,229k dots (non-touch).

Nikon’s touchscreen interface enhances menu navigation and focusing flexibility (touch-to-shoot). Sony’s screen is sharp but you must use physical buttons to navigate.

The Z5’s larger EVF is preferable for framing precise compositions outdoors, while RX100 V’s EVF suffices given the camera’s portability focus.
