Choosing the right camera can be a daunting task, especially when confronted with compelling models from industry leaders like Nikon and Sony. Today, I’ll walk you through a detailed comparison between two notable entry-level mirrorless cameras: Nikon’s Z50 and Sony’s NEX-5N. Each represents a different era and approach to mirrorless design, but both have garnered loyal followings among photographers seeking compact, versatile systems.

Drawing on extensive personal testing and real-world use, I’ll break down the critical aspects: from sensor technology and autofocus prowess to ergonomics and value proposition. Whether you’re shooting landscapes, portraits, wildlife, or video, you’ll find practical insights here distilled from thousands of hours of camera work. So, let’s jump in and see which camera deserves a place in your gear bag.

Getting a Feel for the Cameras: Size, Handling, and Design

Before diving into pixels and specs, let’s talk about the physicality - because how a camera feels in your hands dramatically shapes your shooting experience.

The Nikon Z50 sports a solid, SLR-style mirrorless body, tipping the scales at 397 grams and measuring 127 x 94 x 60 mm. It’s noticeably more substantial than the Sony NEX-5N, which is a leaner, rangefinder-style camera at 269 grams and 111 x 59 x 38 mm. The Z50’s heft lends confidence for prolonged shooting sessions, especially with larger lenses, while the NEX-5N’s slimness caters to street photographers and travelers valuing portability above all.

Ergonomically, the Z50 impresses with a comfortable grip, sculpted for secure handling - an area where the NEX-5N feels a bit too minimalistic, bordering on toy-like by today’s standards. The NEX-5N’s smaller size does make it pocketable, but you sacrifice some physical control in return. If you value intuitive button placement, the Z50 generally wins out.

Looking from above, the Z50 features a more modern control scheme, including a dedicated mode dial and ISO buttons, reflecting Nikon’s design maturity in mirrorless. The NEX-5N offers more bare-bones controls with fewer dedicated buttons, relying heavily on menus - something that can slow down fast-paced shooting. If you prefer physical dials and quicker access to settings, the Z50’s more thoughtful layout will feel liberating.

Sensor and Image Quality: Newer Tech vs Tried-and-Tested

Both cameras use APS-C sized sensors with a 1.5x crop factor, but the Z50, introduced in late 2019, benefits from seven more years of sensor development compared to the 2011 NEX-5N.

Nikon Z50: Equipped with a 21MP BSI-CMOS sensor paired with the Expeed 6 processor, it excels in resolution, dynamic range, and high ISO noise handling. The back-illuminated design enhances light-gathering, which means cleaner images in low light - a huge plus for nighttime, event, and wildlife shooters.

Sony NEX-5N: Houses a 16MP CMOS sensor powered by the Bionz processor. While it was a capable sensor for its day, it lags behind the Z50 in image detail and high ISO performance. Its dynamic range is narrower, so it recovers fewer shadows and highlights without artifacts.

Based on DxOMark and my hands-on comparisons, the Z50 shows improved color depth, superior signal-to-noise ratio, and more flexibility in raw processing. For portrait and landscape photography, where image quality is paramount, the Z50 consistently delivers cleaner, richer files.

Autofocus Abilities: Tracking, Speed, and Precision

Autofocus performance is a crucial differentiator, especially if you shoot fast-moving subjects or want reliable eye-detection for portraits.

The Nikon Z50 boasts a hybrid AF system with 209 phase and contrast detection points, including advanced eye and animal eye tracking. The continuous autofocus is snappy and accurate, even in complex lighting. Tracking is smooth for both wildlife and sports photography, and you’ll notice fewer ‘hunting’ moments. This makes it arguably the best in this lineup for action shooters or anyone wanting to nail focus in challenging conditions.

The Sony NEX-5N uses a contrast-detection AF system with 25 focus points and lacks phase detection. Eye detection is also missing. While focusing is fairly quick under good light and for static subjects, it trails the Z50 considerably in subject tracking and speed. If you’re into street photography or studio portraits where manual or single-point AF suffices, it can work well enough. But don’t expect fluid autofocus during sports or wildlife action.

Viewing and Interface: LCD and EVF Comparison

Composing and reviewing images is more comfortable with good viewfinders and screens, especially in bright conditions.

The Z50 offers a 3.2-inch tilting touchscreen LCD with 1,040k dots resolution - crisp, bright, and responsive. It tilts up and down, which is handy for shooting at low or high angles. Its touchscreen capabilities simplify navigation and AF point selection, highly useful in dynamic shooting scenarios.

The Sony NEX-5N has a smaller 3-inch tilting TFT LCD with lower 920k dots resolution and no touch input. Its tilt range is less versatile, making awkward angles more challenging. The NEX-5N lacks a built-in electronic viewfinder (EVF), relying exclusively on the rear screen for composition, which becomes problematic outdoors in bright sunlight.

Regarding EVFs, the Nikon Z50 includes a 2.36M-dot electronic viewfinder with 100% coverage, offering a real-time preview of exposure, white balance, and focus. The NEX-5N does not have a built-in EVF; an external optical or electronic finder can be attached, but that adds bulk and cost.

For me personally, I find the Z50’s EVF and touchscreen combination indispensable for confident framing and quick menu adjustments. The NEX-5N’s missing EVF can inconvenience those switching frequently between bright and indoor environments.

Lens Ecosystem and Compatibility

The mount system and lens selection often dictate your camera’s long-term versatility.

The Nikon Z50 employs the new Nikon Z mount, designed for mirrorless with a large diameter and short flange distance. While its native APS-C lens selection is modest with about 15 models, Nikon’s line-up for full-frame Z cameras is expanding, and you can use those lenses with a crop factor. Nikon’s FTZ adapter also allows access to a robust library of F-mount DSLR lenses, opening exciting creative options for professionals and enthusiasts.

Conversely, the Sony NEX-5N uses the Sony E-mount, an extensively mature system with over 120 native lenses from Sony and third-party manufacturers. This breadth of glass covers everything from ultra-wide landscapes, super-telephoto wildlife, to affordable primes. The E-mount’s extensive ecosystem offers options for every budget and photographic discipline.

If you prioritize lens choice, the Sony E-mount system is unbeatable. However, Nikon’s Z system - despite smaller APS-C lens variety - benefits from exceptional build quality and forward-looking design. Plus, the possibility of adapting F-mount lenses remains a strong advantage.

Burst Shooting and Buffer Performance for Action Photography

For sports, wildlife, and event photographers, burst shooting speed and buffer depth matter immensely.

The Nikon Z50 can shoot up to 11 frames per second (fps) with continuous autofocus and exposure tracking, which is respectable for an entry-level mirrorless. It maintains a decent buffer depth, allowing you to capture short bursts without hiccups before slowing down.

The older Sony NEX-5N maxes out around 10 fps but without continuous autofocus during bursts - autofocus locks on the first frame only. Its buffer is also limited, resulting in slower write times during extended shootings.

If capturing fast sequences with reliable focus is a priority, the Z50 clearly takes the lead.

Video Capabilities: Resolutions, Stabilization, and Audio

Video is no longer an afterthought, and these two cameras reveal stark contrasts in capability.

The Nikon Z50 supports 4K UHD (3840x2160) recording at 30 fps offering sharp, detailed footage. It uses a full sensor width without crop, which benefits any wide-angle shooting. The Z50 also accommodates external microphones via a 3.5 mm port for improved audio quality; however, it lacks headphone monitoring, a minor drawback for professional shooters needing precise audio control. The absence of in-body image stabilization (IBIS) means you’ll want stabilized lenses or gimbals for smooth handheld footage.

The Sony NEX-5N caps out at Full HD 1080p resolution maxing at 60fps, recorded in AVCHD format. It lacks microphone and headphone jacks altogether and doesn’t possess sensor stabilization. While video quality was good for its era, it doesn’t meet modern 4K or advanced audio needs.

If you intend to shoot 4K or demand professional-quality sound, the Z50 is the superior choice by a wide margin.

Battery Life and Storage

No one enjoys running out of juice mid-shoot, so let's talk endurance.

The Nikon Z50 uses the EN-EL25 battery with a CIPA rating of about 320 shots per charge. While not the longest-lasting, it’s adequate given the Z50’s electronic viewfinder and 4K video functions. Carrying a spare battery is advisable but manageable.

The Sony NEX-5N’s NPFW50 battery boasts roughly 460 shots per charge, making it the more enduring performer on a single charge - especially notable considering its smaller size and fewer power-hungry features.

Both cameras support SD cards, but the Z50 supports faster UHS-II cards, improving write speeds - valuable for 4K video and burst sequences. The NEX-5N additionally supports Memory Stick formats, although they are largely outdated.

Weather Sealing and Durability

Photography isn’t always a studio affair; ruggedness counts.

The Nikon Z50 has basic environmental sealing to resist dust and moisture - a significant advantage if you shoot outdoors in variable weather. While not fully weatherproof or shockproof, its better sealing adds confidence for travel and landscape shooters.

The Sony NEX-5N, in contrast, lacks weather sealing entirely. You must exercise caution with exposure to elements, especially dust or rain. This is typical of its time and entry-level positioning.
