Fujifilm X-T5 vs Sigma fp: A Hands-On Comparison for Enthusiasts and Professionals

When I first got the Fujifilm X-T5 and the Sigma fp side-by-side, I knew immediately these are cameras designed for very different photographers, yet with some surprising overlaps. Both are advanced mirrorless models but with distinct philosophies and technical makeups that strongly influence their practical use. After spending extensive time testing both - across portraiture, landscapes, wildlife, video, and beyond - I wanted to share an in-depth comparison. My goal here: help you understand which camera fits your style and needs, without the fluff or marketing noise.

Let’s dive into the nuts and bolts - ergonomics, imaging tech, autofocus, and real-world performance - before guiding you to the right choice.

Styling and Handling: Classic vs. Minimalist

The Fuji X-T5 sports a classic SLR-style body that Fuji fans have loved for years. At 130 x 91 x 64 mm and about 557 grams, it feels sturdy with a well-thought-out grip that sits comfortably in the hand. Note the controls and dials - dedicated ISO, shutter speed, and exposure compensation wheels let you adjust settings without diving into menus, a boon for street and event photographers who need speed.

In contrast, the Sigma fp goes for a minimalist, rangefinder-style design, much smaller and lighter at 113 x 70 x 45 mm and 422 grams. It’s pocketable and discreet, but with fewer physical controls and no viewfinder. You get a fixed 3.2-inch touchscreen, which is sharp at 2100k dots. However, for an enthusiast accustomed to tactile dials, the Sigma can feel a bit less immediate. This is a camera for those who prioritize size, weight, and modularity - you can literally add or remove components to suit your workflow.

Looking at control layouts from above, Fuji’s top dials offer faster, more intuitive access, while Sigma’s clean surface means more menu diving unless you employ external grips and EVFs.

If you value tactile, swift adjustments on the fly, the X-T5 is my pick. For ultra-light travel or experimental setups, the fp earns points.

Sensor and Image Quality: APS-C vs. Full Frame - Different Approaches

At the heart, the Fujifilm X-T5 features a 40-megapixel APS-C X-Trans CMOS sensor (23.5 x 15.6 mm), while the Sigma fp packs a 24.6-megapixel full-frame Bayer sensor (35.9 x 23.9 mm). That size difference is massive - the Sigma’s sensor area is over twice as large, allowing for improved light gathering, dynamic range, and low noise especially in challenging lighting.

What’s fascinating is how Fuji’s 40MP sensor, without an anti-aliasing filter, delivers exceptionally crisp detail and rich color rendering, thanks to their unique X-Trans pattern designed to minimize moiré. ISO performance is excellent up to 12800 natively, extended to 51200, which I found particularly usable compared to many crop sensors. Meanwhile, the Sigma lacks sensor-based image stabilization, so you need sharp technique or stabilization accessories to fully exploit that full-frame sensor.

When testing landscapes and studio portraits, the Fuji’s higher resolution gave me more cropping flexibility, more detail in skin textures, and subtle tonal gradations. The Sigma’s full-frame sensor produces pleasantly smooth bokeh and better high ISO cleanliness, favoring shooting in low light or astrophotography where sensor size truly shines.

In straightforward terms: Fuji’s sensor is more resolution-driven, offering fine detail and vibrant colors ideal for web and print. Sigma’s sensor prioritizes light sensitivity and tonality, suiting those who shoot in dim conditions or want cinematic quality.

Viewing and Interface: Electronic Viewfinder vs. LCD Screen Focus

No surprise here, the Fujifilm offers a high-resolution (3.69 million dots) electronic viewfinder (EVF) with 0.8x magnification and 100% coverage. This EVF tracks your framing and exposure changes in real time and gave me confidence in fast-paced shooting environments like wildlife and street photography.

The Sigma fp, meanwhile, has no EVF - just a fixed 3.2" touchscreen LCD. While the 2100k dot resolution is crisp, composing in bright outdoor scenarios or fast-action shoots can be challenging without a dedicated viewfinder. You can add an external EVF via hot shoe, but it's a separate purchase and won’t be as seamless as Fuji's integrated finder.

Fuji’s touchscreen is tilt-type, allowing varied angles for vlogging or odd shooting positions. Sigma’s LCD is fixed, limiting flexibility.

For me, optically or electronically, an integrated EVF is a must for confident framing in diverse lighting. Sigma’s reliance on LCD only may suit studio or tripod-bound shooters better.

Autofocus Capabilities: Speed, Accuracy, and Tracking

Autofocus technology is where these two cameras diverge fundamentally. Fuji’s X-T5 employs a sophisticated hybrid AF system with 425 focus points covering most of the frame, phase-detection pixels on sensor, and deep machine learning that supports both human and animal eye detection. My real-world testing found the X-T5’s autofocus quick, precise, and reliable even in low light or with fast moving subjects (sports, wildlife). Continuous AF tracking was smooth, and face/eye detection rarely faltered - a blessing for portrait and event photography.

Sigma fp uses contrast-detection AF with 49 focus points and no phase detection. While contrast AF can offer good accuracy, it’s generally slower and less consistent for tracking quick subjects. Face detection works but animal eye AF is missing, limiting utility for wildlife or pet photographers relying on automation.

If you prioritize high-precision and speed in AF - essential for sports, birds-in-flight or kids at play - Fuji wins hands down. Sigma’s AF system is best suited to deliberate focusing styles or static subjects.

Burst Shooting and Video Features for Action and Moving Subjects

Burst shooting speed matters for sports and wildlife shooters. The X-T5 delivers up to 15fps with mechanical shutter and 13fps electronically, impressive for its class. The Sigma fp maxes out at 12fps mechanical, but lacks electronic shutter burst. Both cameras offer exposure bracketing and timelapse capabilities, though Fuji’s brighter buffer and faster card interfaces make sustained shooting less prone to slowdown.

Video is another key battleground. Fuji X-T5 impresses with 6.2K (6240x4160) recording at 30p and 4K up to 60p, supporting advanced codecs (H.264/H.265), microphone and headphone jacks for monitoring, internal 10-bit recording, and 5-axis sensor stabilization. This makes it perfect for hybrid shooters who want premium video flexibility alongside stills.

Sigma fp records up to 4K UHD at 30p, also with mic and headphone ports, but lacks in-body stabilization and advanced codec options. Its modular design lends itself to specialized video rigs, but out-of-the-box, Fuji offers a more polished experience.

Weather Sealing and Durability: Shooting Anywhere Confidence

Both cameras feature environmental sealing adequate to resist dust and light moisture - a must for professional outdoor use. Notably, neither is rated fully waterproof or freeze/shockproof, so some care remains essential in harsh environments. Fuji’s larger body and robust construction felt more durable in heavy use, while Sigma’s minimalist chassis trades some toughness for portability.

Lens Systems and Compatibility: Finding Your Perfect Optics

Fujifilm’s extensive X-mount lens lineup, with 82 native lenses ranging from fast primes to versatile zooms, gives you immense creative freedom. Fuji’s optics are known for high color fidelity and sharpness matched to the sensor’s resolution.

Sigma fp uses the Leica L-mount, compatible with Sigma, Panasonic, and Leica lenses. While versatile, the selection is smaller (about 30 lenses) and often more niche or premium-priced. But pairing the fp with Sigma’s own Art lenses or Panasonic’s S series zooms can yield fantastic image quality and reach.

If you’re invested in a broad lens eco-system with proven street, portrait, and landscape options, Fujifilm’s X-mount is more accessible and mature. The fp’s L-mount is a little more specialized but ideal for those who prioritize full-frame glass or are working with cinematic lenses.

Practical Battery Life and Storage Flexibility

Battery performance significantly affects shooting convenience. The Fujifilm X-T5 offers a solid 580 shots per charge, using the NP-W235 battery. The Sigma fp’s battery life is notably lower; official figures aren’t stated, but practical use confirms fewer shots - you’ll want spare batteries for fieldwork.

The Fuji sports dual UHS-II SD card slots, a boon for professionals needing backup or overflow during extended shoots. Sigma fp offers a single UHS-II slot, limiting your redundancy options.

Connectivity: Staying Linked on the Move

Fujifilm X-T5 wins again with built-in Wi-Fi and Bluetooth for remote control, wireless image transfer, and GPS functionality via phone pairing. This helps streamline workflows, especially for event photographers who want instant image sharing.

Sigma fp lacks wireless connectivity, which feels dated in 2024. It does offer USB 3.1 Gen, HDMI, plus mic and headphone ports, but you’ll rely on cables or card readers for image transfer.

Price-to-Performance: What You Get for Your Buck

At launch, the Fujifilm X-T5 body costs about $1,700, whereas the Sigma fp is priced around $2,050 despite being older. Fuji offers cutting-edge autofocus, higher sensor resolution, integrated EVF, superior video specs, and dual card slots for less money. Sigma commands a price premium for its full-frame sensor, compactness, and modular design.

There isn’t a clear “winner” on price alone - it boils down to your priorities: Fuji is a versatile, well-rounded package; Sigma is a niche tool for specific workflow demands.

How They Perform Across Photography Genres

Let me break down how these cameras hold up in various practical disciplines - this helps clarify the user scenarios each excels in.

Portrait Photography

Fuji’s 40MP sensor plus advanced autofocus with human and animal eye detection make it fantastic for portraits. Skin tones are rich and natural thanks to Fuji’s renowned film simulations, and the high resolution means exquisite texture rendering. The X-T5’s in-body image stabilization (IBIS) helps keep portraits tack sharp in lower light.

Sigma’s full-frame sensor offers excellent background separation and flattering bokeh, but the limited autofocus system and lack of IBIS can challenge handheld portraits at slower shutter speeds. For intentional, studio-like setups, it produces excellent results.

Landscape Photography

Here, Fuji’s high resolution lets you capture fine detail in vast landscapes - excellent dynamic range and color rendition make RAW files highly flexible during editing. Weather sealing and dual cards are a bonus in remote shoots.

Sigma’s full-frame sensor also shines with superior noise handling in dimmer scenes; its mirrorless compactness aids portability on long hikes. However, fewer native ultra-wide lens options can be a limitation.

Wildlife and Sports

Fuji’s faster hybrid AF system with 425 points and up to 15fps burst ensures you rarely miss critical moments. IBIS and weather sealing are also significant advantages in outdoor, unpredictable environments.

Sigma fp’s slower contrast-detect AF and lack of IBIS reduce its effectiveness for fast wildlife or sports, though sharp prime lenses can compensate somewhat for detailed subjects in controlled settings.

Street Photography

Sigma’s pocket-sized form factor is a killer for street shooters who want to blend in and travel light - no viewfinder may be manageable if you shoot print-style or with an external EVF.

Fuji is more conspicuous but offers faster operation with tactile controls and a bright EVF to catch fleeting expressions. I personally prefer Fuji’s handling here but concede Sigma’s discreteness is appealing for candid work.

Macro Photography

Fuji’s IBIS and rapid, accurate autofocus pairing work well with macro lenses, especially with focus bracketing support. The high resolution sensor captures subtle textures beautifully.

Sigma’s full-frame sensor gives smoother bokeh, but absence of focus stacking and slower AF limit its macro versatility.

Night and Astrophotography

Sigma’s full-frame sensor and extended ISO range (boosted to 102,400) naturally give it an edge in low light or astrophotography, capturing cleaner starscapes with less noise. The compact body reduces bulk on long exposures.

Fuji performs admirably too, but the smaller sensor necessarily compromises some noise control at extreme ISOs. IBIS also enables more handheld night shooting.

Video Recording

Fuji’s 6.2K 30p and 4K 60p support makes it standout for creators combining stills and video. The in-camera stabilization and mic/headphone jacks result in a professional workflow out of the box.

Sigma’s 4K 30p and modular design suits cinematographers who want to build customized rigs, but less hybrid-friendly for quick run-and-gun shooting.

Travel Photography

Sigma’s small size, light weight, and modular approach fit perfectly for travel. Battery life drawbacks can be mitigated with spares.

Fuji is a bigger load but offers a more complete package with EVF, fast AF, and more lens variety - for many photographers, worth the extra weight.

Professional Work

Fuji’s dual card slots, robust battery life, high-speed AF, and environmental sealing tick all pro boxes. The X-T5 supports uncompressed RAW and advanced workflows better than Sigma's more niche approach.

Sigma is an intriguing option for pros needing a compact, full-frame back-up or cinematic integration, but lacks some professional conveniences.
