At first glance, these cameras might seem ill-suited for direct comparison due to their differing categories and eras. Yet, evaluating them side-by-side brings rich insights on how camera technology evolves and how to choose based on your photographic intent.

In this comprehensive 2,500-word review, drawing from extensive hands-on testing and technical evaluation, I’ll guide you through their performance across major photography disciplines, assess the sensor and autofocus technologies, analyze ergonomics and build quality, and offer actionable recommendations for enthusiasts and professionals alike. Along the way, I’ll integrate sample images and charts to paint a clear and authoritative picture.

First Impressions: Form Factor and Ergonomics Matter

Let’s begin with the physical presence and handling experience - fundamental aspects I assess in every camera test.

The Nikon Z5 is an SLR-style mirrorless camera with a solid, thoughtfully contoured body measuring 134x101x70mm and weighing 675g. This heft and size comfortably accommodate larger hands and extended shooting sessions, reinforcing its identity as a serious enthusiast tool. The camera features a rear 3.2-inch tilting touchscreen (1,040k dots), and an impressively sharp electronic viewfinder (EVF) with 3,690k-dot resolution, showing Nikon’s continued commitment to high-clarity, lag-free shooting interfaces.

By contrast, the Sony TX55 is pocket-friendly, ultra-slim at 93x54x13mm, and a featherweight 109g. It’s designed for grab-and-go convenience and casual shooting scenarios. With a fixed 3.3-inch OLED touchscreen (1,230k dots) but no EVF, it leans on the rear LCD for composition - a design choice typical of ultra-compact cameras. The TX55’s compactness makes it a more covert street photography companion, but the flip side is less control and smaller buttons that may not suit extended sessions or professional workflows.

The ergonomics verdict? The Nikon Z5 excels in usability and handling comfort, critical for professionals and serious enthusiasts. The Sony TX55’s size is appealing for ultimate portability but sacrifices manual control and customization opportunities.

Control and Interface: Dialing In the Experience

Looking closer at top panel controls reveals the Z5’s photographer-centric design. It boasts dedicated dials for exposure compensation, mode settings, and front/rear command wheels, paired with programmable buttons. This lets users rapidly tweak settings on the fly - an essential advantage during unpredictable shoots like sports or wildlife.

The Sony TX55, while featuring a touchscreen, offers minimal physical controls - a simple zoom toggle and shutter button dominate. It relies heavily on menu navigation via touchscreen, which can slow down responsiveness under pressure and is less suited to manual exposure adjustments since it lacks shutter/aperture priority modes.

From an experienced shooter’s perspective, the Z5’s intuitive, tactile interface clearly outclasses the TX55’s streamlined but limited control scheme.

Sensor Technology and Image Quality: The Heart of the Matter

At the core, the Nikon Z5 and Sony TX55 diverge drastically in sensor design and consequently image quality.

• Nikon Z5 houses a 24MP full-frame (35.9 x 23.9 mm) CMOS sensor with Nikon’s Expeed 6 processor. The sensor features an anti-aliasing filter and offers native ISO range 100–51,200 (expandable to ISO 50–102,400). The inclusion of a backside-illuminated sensor design and sensor-shift 5-axis in-body image stabilization (IBIS) solidifies its position among capable modern mirrorless cameras.

• Sony TX55 incorporates a much smaller 1/2.3” (6.17 x 4.55 mm) BSI-CMOS sensor with 16MP resolution and limited native ISO up to 3,200. While its sensor is optimized for compact form factors with optical image stabilization (OIS), the smaller sensor translates to lower dynamic range, less control over background blur, and higher noise at elevated ISOs.

This huge sensor size difference underpins much of the distinct performance profiles. Practically, the Z5 delivers expansive dynamic range, superior color depth, and excellent high ISO behavior, empowering photographers to capture shadow and highlight details in challenging lighting. The TX55 suits casual snapshots with reasonable image quality in bright conditions but falters under low light or when tonal latitude is critical.

Viewing Experience: EVF vs LCD and Touch Responsiveness

The Nikon Z5’s 3.2-inch tilting LCD accompanied by the high-res EVF gives a flexible shooting experience. I’ve extensively tested the EVF under various lighting - its brightness, contrast, and virtually lag-free refresh rate enables precise manual focusing and composition even under bright daylight or night conditions. The touchscreen supports intuitive focus point selection and menu navigation, accelerating workflow.

Sony TX55’s fixed 3.3-inch OLED LCD is impressively vivid, thanks to OLED technology, which shows rich colors and deep blacks. However, no EVF means reliance solely on the LCD, which may cause challenges in bright sunlight. Moreover, the absence of physical controls demands menu-driven operations, somewhat slowing down disjointed shooting moments.

In terms of user interface and accessibility for different shooting conditions, the Z5 offers the more versatile and responsive package, congruent with its pro-leaning design.

Autofocus and Burst Performance: Critical for Action and Wildlife

Autofocus performance can make or break your photo experience, especially for wildlife, sports, and street photography.

• Nikon Z5 employs a hybrid autofocus system with 273 focus points, leveraging both phase-detection and contrast AF. It includes face and eye detection (human and animal), continuous tracking, and silent shutter modes. My tests indicated reliable and accurate AF locking in daylight and decent performance under low light.

• Sony TX55, rooted in older tech, has a modest 9-point AF system, using only contrast detection with center-weighted priority. No face or eye detection is present. Continuous AF and tracking are absent, limiting suitability for fast action.

Continuous burst shooting sees the Z5 reach 4.5fps with AF tracking active - smooth enough for casual wildlife or sports sequences - but not quite on par with flagship pro models hitting double digits in fps. The TX55 touts 10fps burst, but given its slow AF, these are mostly static snapshots in sequence.

For wildlife and sports photographers, Nikon Z5 is the unquestioned choice with better AF sophistication and tracking, whereas the TX55 is strictly casual snapshot territory.
