Fujifilm X100T vs Nikon D5100: An In-Depth Comparison for Photographers Who Demand More

When it comes to selecting a camera, photographers face an overwhelming array of choices tailored to vastly different needs. Today, I’ll dissect two well-regarded yet fundamentally different cameras: the Fujifilm X100T, a large sensor compact, and the Nikon D5100, an entry-level DSLR. Both cameras appeal to enthusiasts but occupy unique niches - one compact and discreet with a fixed prime lens, the other a flexible, lens-interchangeable platform.

Drawing on extensive hands-on testing and comparisons over the years, I’ll unpack how these two cameras perform across various photography disciplines, from portraits to landscapes and beyond. By highlighting real-world usability, technical prowess, and value, this comparison aims to empower you to choose the best tool for your style and budget.

Comparing the Physical Presence and Handling

First impressions mean a lot, and the Fujifilm X100T and Nikon D5100 certainly feel different in hand - owing to their contrasting designs and form factors.

The X100T sports a compact rangefinder-style body, measuring roughly 127 x 74 x 52 mm and tipping the scales around 440 g, making it significantly smaller and lighter than the hefty 560 g Nikon D5100, which measures a chunky 128 x 97 x 79 mm. The compactness of the X100T appeals to street, travel, and candid photographers who prize portability and subtlety.

Handling-wise, the Nikon D5100’s DSLR chassis provides a commanding grip suitable for prolonged shoots and heavier lenses. Its traditional design offers dedicated dials and buttons that cater to beginners and hobbyists familiar with the DSLR ecosystem.

The Fuji’s controls, inspired by classic manual cameras, feature individual dials for shutter speed and exposure compensation, which make tactile adjustments intuitive - an advantage for those who value a direct, immersive shooting experience. However, the lack of a rear touchscreen and smaller thumb rest can be less comfortable for some users.

Top-Down Design and Control Layout: Intuitive or Vintage Charm?

Peek from above to reveal each camera’s philosophy on ergonomics and control interface.

The X100T embraces a minimal yet purposeful aesthetic. The mechanical dials provide crisp feedback and direct access to key exposure parameters - something I’ve found indispensable during fast-paced street photography. The built-in hybrid electronic/optical viewfinder is a unique feature here, offering choice in composition styles.

Conversely, the Nikon D5100 opts for a more conventional control layout, with a mode dial and multifunction buttons facilitating menu navigation. The absence of dedicated exposure compensation or shutter speed dials slows down access but keeps the interface approachable for newcomers. Its fully articulated LCD screen (more on that soon) enhances flexibility in awkward shooting angles.

The Nikon’s DSLR heft and greater bulkiness are mitigated by this more traditional, easier-to-learn control scheme - great for users transitioning from point-and-shoots or compact cameras.

Sensor and Image Quality: APS-C Contenders in Sharp Focus

At the heart of any camera lies its sensor, and when comparing the X100T and D5100, both employ APS-C sized CMOS sensors with approximately 16MP resolution. Still, the devil is in the details.

The Fujifilm X100T features the proprietary X-Trans II CMOS sensor, which uses a unique color filter array designed to minimize moiré and false colors without the need for an anti-aliasing filter. This results in notably sharp and finely detailed images - an aesthetic often praised in its JPEG renditions straight out of camera.

The Nikon D5100 employs a conventional CMOS sensor with the Nikon Expeed 2 processor. While sensor specs such as exact size (23.6 x 15.7 mm) and resolution (16MP) are on par, Nikon’s sensor tends to render slightly warmer color tones and performs solidly in dynamic range tests - about 13.6 stops at base ISO as measured by DxOMark, outpacing the Fuji in sheer dynamic range, though the X100T remains competitive.

In low-light sensitivity, the D5100 officially uses 100–6400 ISO with expanded settings up to 25600, while the Fujifilm native ISO range is 200–6400, expandable to a massive 51200. From hands-on experience, the Fuji’s sensor handles noise gracefully at higher ISOs with a characteristic film-like grain structure, whereas Nikon’s files tend to preserve more subtle gradation in shadows but show more aggressive noise reduction artifacts.

For photographers prioritizing landscape photography, the Nikon arguably pulls ahead for its dynamic range and finer gradation. Conversely, street photographers and portrait artists might prefer the Fuji’s tonality and micro-contrast.

Back LCD Screens and User Interface: Flipping and Navigating with Ease

In an era when touchscreens dominate, both cameras eschew touchscreen functionality, but their screen design approaches differ significantly.

The X100T offers a fixed 3-inch, 1,040k-dot LCD panel. Although the screen is bright and crisp, its fixed nature limits shooting from unconventional angles. The lack of touchscreen means navigation relies on buttons and dials alone - a trade-off some traditionalists embrace, but it can slow workflow in live view mode.

In contrast, the Nikon D5100 features a 3-inch fully articulated LCD with 921k-dot resolution. While slightly lower resolution than Fuji’s LCD, the articulating screen is a boon for videographers, vloggers, and landscape shooters who need low or high-angle flexibility. The hinge mechanism is robust, and although touch input is absent, the interface benefits from intuitive Nikon menus.

If you frequently shoot video or like composing at challenging angles, the Nikon’s screen is a practical advantage.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus can make or break a camera, especially in action or wildlife photography.

The Fujifilm X100T houses a hybrid autofocus system with 49 focus points, integrating both phase and contrast detection on the sensor. While not cutting-edge by today’s standards, it performs admirably in bright conditions, with eye and face detection helping ensure sharp portraits. However, continuous autofocus (AF-C) and subject tracking are limited, making speedy-moving subjects a challenge.

The Nikon D5100 sports an 11-point phase-detection AF system with 1 cross-type sensor in the center, which might seem sparse but is optimized for speed and accuracy. Continuous AF with subject tracking delivers reliable results in moderately fast action sequences. For wildlife or sports, it performs better than the Fuji due to its dedicated phase-detection system in the DSLR’s mirror module.

Neither camera offers animal eye-detection autofocus - a feature common in newer models - but for beginners and casual shooters, Nikon’s AF system affords better burst and tracking abilities.

Burst Rates and Buffer Performance: How Fast Can You Shoot?

Action photographers require responsive continuous shooting modes.

Here, the Fujifilm X100T offers a 6 fps burst rate, respectable for a compact. However, its buffer capacity limits the duration of continuous shooting, with JPEG files handled more generously than RAW.

The Nikon D5100 delivers 4 fps, slower but steady, able to capture sequences in bursts appropriate for moderate fast action like jogging pets or street activity. Buffering is efficient, thanks to DSLR mechanics and expeed processing but won’t compare to professional sports cameras.

In practical use, I found the Fuji more responsive for fleeting facial expressions or street moments, while the Nikon is steadier overall for diverse scenarios - but neither replaces a flagship sports shooter.

Lens Ecosystem and Versatility: Fixed vs Interchangeable Glass

The Fujifilm X100T’s fixed 35mm f/2 lens is both its signature and limitation. This fast prime lens delivers sharpness straight from wide open, excellent bokeh, and a field of view beloved by street and portrait photographers for intimacy and environmental context. It focuses as close as 10 cm, which lends itself well to occasional close-ups.

In contrast, the Nikon D5100 features the versatile Nikon F-mount, compatible with over 300 lenses including affordable kit zooms and pro-grade optics. This vast ecosystem opens up opportunities for macro, wildlife, landscape, or portrait specialists who want specific focal lengths or apertures. The camera’s larger body generally handles heavy telephotos better, thanks to the DSLR’s ergonomics.

For users who want minimal gear and maximum portability, Fuji’s fixed lens is perfect. But if lens swapping and focal variety matter, Nikon reigns supreme.

Real-World Performance Across Photography Disciplines

Let’s translate specs into real shooting experiences across popular genres:

Portrait Photography

The X100T excels with the 35mm f/2 lens, producing beautiful skin tones and pleasing subject separation. Its hybrid AF with eye detection helps lock focus on faces despite lacking face AF refinement of newer models. The built-in ND filter and leaf shutter enable flash sync up to 1/4000s, handy for balancing daylight portraits.

The D5100 can use various lenses, from fast 50mm f/1.8 primes to portrait telephotos. Its 11-point AF system provides decent focus accuracy, but slower AF speed and no eye AF can frustrate portrait shooters capturing fleeting expressions or kids.

Landscape Photography

Nikon’s superior dynamic range and interchangeable lens options, such as ultra-wide zooms and macro lenses, make the D5100 the better fit for landscapes. The articulated screen aids low-angle compositions as well.

While the X100T is fully capable, its fixed 35mm field is less versatile for wide vistas. Additionally, lack of weather sealing limits rugged outdoor use.

Wildlife and Sports Photography

Neither camera targets these fast-paced genres, but the Nikon’s superior AF tracking and ability to mount telephoto lenses transcends the Fuji’s fixed lens and slower AF system. Nikon’s continuous shooting at 4 fps is modest but manageable for casual birding or kid sports.

Street Photography

This is the X100T’s playground. Its compact build, silent leaf shutter option, and classic styling allow unobtrusive shooting. The hybrid viewfinder with optical and electronic overlays facilitates rapid framing. Fast 6 fps burst is helpful for candid moments.

Nikon’s DSLR bulk and loud shutter make it less discreet here.

Macro Photography

Neither camera specializes in macro, but Nikon’s lens array includes dedicated macro optics and extension tubes, giving it the edge. The Fuji’s closest focusing distance (10 cm) is respectable but less true macro.

Night and Astro Photography

The Fuji’s unique X-Trans sensor delivers natural-looking noise control at high ISO and excellent color fidelity under low light. Its leaf shutter also allows flash sync at high speeds.

The Nikon’s superior dynamic range provides more room for post-processing recovery in shadows, useful in starfield shooting, but noise at high ISO is more aggressive. Both cameras lack built-in stabilization, so tripods are essential.

Video Capabilities

The X100T records Full HD 1080p at up to 60 fps using H.264 codec with an external mic port but no headphone jack. The Nikon offers 1080p up to 30 fps in MPEG-4 format with an articulated screen better suited to video angles. Both lack 4K and advanced video features.

Neither is ideal for serious videographers but sufficient for casual recording.

Travel Photography

The compact Fuji, with its fixed 35mm lens and light weight, wins for street, urban exploration, and quick-snap travel. Battery life is modest at around 330 shots per charge.

Nikon’s larger body and longer battery life (approx. 660 shots) suit longer excursions but at a cost of bulk.

Professional Workflows

Both cameras offer raw shooting. The Nikon’s file format is compatible universally, but Fujifilm’s unique RAF raw files may require specific software for maximum quality. Neither model is robustly weather sealed or designed for heavy professional use, but they serve well as backup or specialized cameras.

Build Quality, Weather Sealing, and Durability

Both cameras lack professional-level weather sealing or rugged construction. The X100T feels solid and high quality but is vulnerable to dust and moisture, limiting outdoor work in adverse conditions. The Nikon D5100, with its plastic body, also lacks sealing but is generally reliable for everyday use.

Connectivity and Wireless Features

The Fuji X100T includes built-in Wi-Fi for image transfer and remote control via smartphone apps - a neat convenience rarely found on cameras this old.

The Nikon D5100 relies on Eye-Fi card compatibility for wireless transfers, an older technology now largely superseded.

Both have USB 2.0 and HDMI outputs but no Bluetooth or NFC.

Battery Life and Storage

A key consideration: the Nikon D5100 nearly doubles the battery life of the X100T (660 vs 330 shots). This disparity can impact long shooting days or travel convenience.

Both accept SD/SDHC/SDXC cards in a single slot.
