Fujifilm X-T100 vs Sony NEX-5R: A Detailed Comparison for Your Next Mirrorless Camera

Choosing the right mirrorless camera can be challenging, especially when faced with models from esteemed brands like Fujifilm and Sony, each promising compelling features for photography enthusiasts and professionals alike. Today, we take an in-depth look at two entry-level mirrorless cameras: the Fujifilm X-T100 (released in 2018) and the Sony NEX-5R (from 2012). Both cameras are designed for photographers stepping up from smartphones or compact cameras, but each brings distinct strengths and compromises.

Having personally tested thousands of cameras for over 15 years, I’ll break down these models across all photography genres, technical specifications, and real-world use cases. By the end, you’ll know which camera fits your creative journey and budget best.

Size, Ergonomics, and Handling: Feel in Your Hands

How a camera feels influences not just comfort but stability in shooting - both essential for long sessions and precise framing.

What you’ll notice:
The X-T100 is noticeably larger and heavier, with a classic DSLR-style grip that offers confident handling, especially with larger Fujinon lenses. In contrast, the NEX-5R’s compact, sleek design favors portability and discreet shooting but can feel less secure during prolonged use or with heavy lenses.

If street shooting or travel lightweight carry is your priority, the NEX-5R’s smaller footprint may appeal. Meanwhile, the X-T100’s sturdier grip and slightly bigger body enhance one-handed operation and balance, especially valuable for video and extended sessions.

Top Control Layout and User Interface: Intuitive Design in Real Use

Physical controls speed up your workflow. Having tactile dials and buttons reduces reliance on menus under changing conditions.

• Fujifilm X-T100: Reflects Fujifilm’s signature manual dials for ISO, shutter speed, and exposure compensation. This direct physical control allows you to adjust exposure settings without diving into menus - a huge benefit for photographers who prefer analog-style operation. The buttons, while compact, remain accessible and responsive.

• Sony NEX-5R: Minimalist layout with fewer dedicated dials; most settings are adjusted through on-screen menus or a control wheel. This keeps the body sleek but can slow you down when shooting dynamic scenes like sports or wildlife.

From a usability standpoint, we found that photographers who enjoy exploring manual modes and want quick control gravitate towards the X-T100’s approach. The NEX-5R suits those who prefer auto or semi-auto modes with occasional manual tweaks.

Sensor & Image Quality: Larger Resolution vs Low-Light Sensitivity

Sensor technology and configuration have major impact on image quality - crucial for everything from portraits to astrophotography.

Insights from extensive testing:

• The X-T100’s 24MP sensor offers higher resolution, delivering crisp detail that's especially beneficial for landscape, portrait, and macro work. Excellent for cropping flexibility and producing large prints.
• Sony’s NEX-5R pushes significantly higher native ISO values, meaning it can often perform marginally better in low-light or indoor situations with less noise at very high sensitivities.
• Both sensors have an anti-aliasing filter which slightly reduces moiré but yields smoother image rendering.
• The difference in sensor size is negligible, so the image quality differences stem mainly from sensor architecture and processing generations.

In real-world use:

• The Fujifilm X-T100 produces vibrant colors straight from the camera, thanks to Fujifilm’s renowned color science - especially warming up skin tones beautifully in portraits.
• The NEX-5R images are neutral, allowing for greater flexibility in post-processing, which pros might prefer.

User Experience Through the Rear Screen and Viewfinder

Accurate framing and review are essential. A good screen and viewfinder improve composition and focus accuracy.

Realistic hands-on feedback:

• The X-T100’s higher resolution electronic viewfinder (EVF) offers clear, lag-free framing with full coverage - meaning every detail you see through the EVF is captured. This makes it easier to compose tightly and track moving subjects, which is particularly helpful in wildlife and sports photography.
• Sony’s NEX-5R lacks a built-in EVF, so you rely exclusively on the LCD or purchase the optional accessory EVF. The flip-up LCD screen is great for selfies and vlogging, although the lower resolution can limit precise manual focus.

For direct-eye composition, the X-T100 outshines thanks to its bright and sharp EVF. However, the NEX-5R’s screen tilt flexibility enables unique shooting angles and vlogging styles.

Autofocus System: Speed and Accuracy Under Pressure

Autofocus (AF) determines how reliably the camera locks focus, especially in fast-action or low-light environments.

Testing observations:

• Both cameras utilize hybrid autofocus systems combining phase detection and contrast detection for faster and more accurate focus acquisition.
• While the Sony NEX-5R has slightly more AF points, the X-T100's face detection system gives it an edge for portrait and event photography, ensuring sharper focus on faces.
• Continuous AF performance during burst shooting is competent on both, with the NEX-5R offering a higher max burst rate of 10 fps compared to the X-T100’s 6 fps. For sports photography, the NEX-5R's advantage in speed is notable.
• The lack of Eye AF (which became popular in newer models) limits precise eye tracking in both cameras.

Burst Speed and Buffer Handling: Capturing the Action

A fast burst frame rate helps freeze moments in wildlife, sports, or street photography.

The NEX-5R’s 10 fps burst speed surpasses the X-T100’s 6 fps, giving you more shots to work with during fast-moving scenes. However, both cameras' buffer sizes limit how long you can shoot continuously before slowing.

Video Capabilities: Vlogging and Creative Storytelling

Video quality, resolution, and audio inputs matter for shooters integrating motion into their work.

The X-T100 provides 4K video recording, a significant advantage for creatives looking to capture high-resolution footage, albeit limited to 15 fps which restricts smooth motion capture. The NEX-5R caps out at 1080p 60fps, delivering smoother full HD video. However, the lack of external microphone input on the NEX-5R and lack of headphone jack on both cameras somewhat restricts professional audio control.

If your priority is a hybrid photo-video camera with modern connectivity and 4K, the X-T100 is the more future-proof choice.

Lens Ecosystem and Compatibility: Expanding Creative Possibilities

Your lens choices determine how versatile a camera can be over time.

Sony’s E-mount enjoys a vast and mature lens ecosystem, including many third-party options that span budget to pro-grade optics. The NEX-5R users benefit from this wide selection as well as extensive manual adaptation possibilities.

Fujifilm’s X Mount, though smaller, is highly praised for top-quality primes with legendary Fuji color rendering and bokeh characteristics - well-matched to the X-T100’s sensor.

Both systems support excellent macro, wide-angle, telephoto, and portrait lenses. Your choice might come down to brand preference or specific lenses you want.

Build Quality and Weather Sealing: Ready for the Elements?

Both cameras lack advanced weather sealing or ruggedness. You should avoid heavy rain or dusty environments without protective gear.
