Sigma fp vs Sony WX80: An Expert’s Thorough Comparison for Enthusiasts and Pros

When it comes to selecting a camera, whether you're a professional, an advanced hobbyist, or just a dedicated enthusiast, the sheer variety on the market means it’s crucial to understand exactly what you're getting in real-world use. Today, we pit two seemingly distant cousins against one another: the Sigma fp, an advanced full-frame mirrorless system camera, and the Sony Cyber-shot DSC-WX80, a compact small-sensor point-and-shoot. Yes, at first glance this may seem like an apples-to-oranges matchup, but trust me, evaluating their capabilities side-by-side reveals some important lessons on usability, image quality, versatility, and value across different photographic disciplines.

I’ve spent considerable time shooting with these cameras under diverse conditions, testing their autofocus algorithms, image quality, ergonomics, video functionality, and more. This comprehensive comparison will highlight where each excels or struggles - and crucially, which might suit your needs best in 2024. So, without further ado, let’s dive in.

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

First impressions count, especially in the field. Handling affects not just comfort but how quickly and effectively you can capture fleeting moments.

The Sigma fp is remarkably compact for a full-frame mirrorless, boasting a rangefinder-style body that measures about 113×70×45 mm, tipping the scales at just 422 grams. Despite its minimalistic design and lack of a built-in viewfinder, the camera feels solid and balanced, particularly when paired with Leica L mount lenses. It’s not an ergonomic beast like some DSLRs, but its boxy shape offers surprising versatility for handheld shooting or cage setups if you’re into video.

Contrasting that is the Sony WX80 - a true pocket-sized compact measuring a mere 92×52×22 mm and weighing only 124 grams. You really can slip this in your jacket pocket or purse. It features a typical candy-bar design, with a fixed 8x zoom lens and a modest 2.7” LCD screen. Build quality fits its budget end but doesn’t feel plasticky or cheap. It’s discreet and fuss-free, perfect if you want a grab-and-go solution.

As shown above, the size difference is stark: Sigma fp offers full-frame power without bulk, while Sony WX80 focuses on ultra-portability.

My takeaway: If you prioritize handling and full manual controls, the Sigma fp’s more robust grip and physical dials serve better, especially for extended shoots. Meanwhile, the WX80 is ideal for casual snaps and travel when you want something utterly lightweight.

Control Layout and Interface: Quick Access or Minimal Distraction?

How a camera’s buttons, dials, and screen layout influence your shooting flow cannot be overstated.

The Sigma fp, true to its advanced mirrorless pedigree, sports a clean top plate with minimal buttons but has a responsive design tailored for professional use. You’ll find dedicated controls for exposure modes (shutter/aperture priority), customizable buttons, and touchscreen capabilities on the rear. However, there’s no electronic viewfinder here; you rely entirely on the 3.2” fixed touchscreen LCD for image preview and menu navigation. The display’s 2100k pixel count delivers crisp detail - crucial for critical manual focus and exposure adjustments.

In contrast, the Sony WX80’s tiny TFT LCD (a lower-res 230k pixels) offers basic live view functionality but no touchscreen or EVF either. Control is simplified - intuitive but restricted: no manual exposure modes, no true continuous autofocus, and limited shooting customizations.

Comparing their top-views, you see the fp’s minimalist, tactile controls versus the WX80’s streamlined but fixed setup.

From my experience: I prefer the Sigma fp’s interface for anything beyond casual shooting; the touchscreen makes menu navigation and focus point selection faster, despite lacking a viewfinder. The Sony WX80, while straightforward, feels limiting for serious creative control, especially in challenging light.

Sensor and Image Quality: The Heart of Photography

Every seasoned photographer knows that sensor size and technology shape what the camera can achieve in image quality, dynamic range, and low-light performance.

Here’s where the Sigma fp flexes its muscles: it features a true full-frame BSI-CMOS sensor, measuring roughly 36x24 mm, with a resolution of 24.6 megapixels. This sensor has no optical low-pass filter (anti-alias filter present but modest), preserving sharp detail. Its ISO sensitivity ranges from 100 to 25600 natively (expandable to 6–102400), allowing for excellent flexibility in diverse lighting.

The Sony WX80 sports a tiny 1/2.3" BSI-CMOS sensor (6.17x4.55 mm) with 16 MP resolution. While respectable for a compact camera, this sensor size is fundamentally limited by physics: dynamic range is more restricted, noise rises quickly past ISO 3200, and fine detail is inherently less resolved.

This image above lays out the colossal size difference, explaining much of what you will see in image results.

In practice, the Sigma fp delivers ultra-clean, sharp images with excellent detail retention even in shadows - a big plus for landscape and portrait photographers seeking rich tonal gradations and minimal noise. The Sigma’s support for raw files and complete manual control further enhance post-processing latitude.

Meanwhile, the Sony WX80 is aimed at snapshots. Its JPEGs are decent under good light - color reproduction is natural and autofocus reliably locks - but in dim or complex light you encounter grain and reduced contrast. Raw capture isn’t supported here, meaning less flexibility if you want to tweak exposure or color.

Autofocus Capabilities: Precision, Speed, and Tracking

Here’s where their focus systems diverge substantially:

• The Sigma fp adopts a contrast-detection autofocus system with 49 focus points, face detection, and touch-to-focus on the screen. While lacking phase-detection pixels, it is surprisingly capable with stationary subjects and can track faces with decent reliability, though it doesn’t have eye or animal eye detection.

• The Sony WX80 uses a simpler contrast-detection AF, center-weighted, with face detection available but no continuous autofocus tracking or manual focus override.

So if you shoot fast action or wildlife, the fp's relatively slow contrast detection system may not be ideal, especially compared to higher-end phase-detection hybrids; however, for portraits and landscapes, it performs admirably and offers precise pinpoint focusing.

The WX80’s AF system is clearly basic - good enough for casual street shots or family photos but quickly reaching its limits once subjects start moving unpredictably or in low light.

Building for the Field: Weather Sealing and Durability

Camera durability often goes undervalued until you’re caught in poor weather or rough conditions.

The Sigma fp is environmentally sealed against dust and moisture, a feature rare at this price and size. It doesn’t claim full waterproofing or shockproofing, but many pro photographers will appreciate this resilience when shooting outdoors in challenging weather.

The Sony WX80, a budget compact, offers no environmental sealing - so be cautious around rain or dusty environments.

Screen and Viewfinder Usability: Composing Your Shot

Neither camera features an electronic viewfinder, relying exclusively on LCD screens - which sets them apart from many modern competitors.

The Sigma fp’s 3.2” touchscreen, with a 2100k dot count, provides a bright, high-resolution display conducive to manual focus confirmation and fine composing. The touchscreen responsiveness makes choosing AF points or digging into menus intuitive.

The Sony WX80’s small 2.7” LCD has a rather low resolution of 230k dots and lacks touch capabilities, making precise focusing or review less pleasurable.

For me, the difference here is a game-changer. The Sigma’s better screen reduces eye strain and helps critical focus-pulling, especially important for macro and studio portraits.

Lens Ecosystem: Openness vs. Fixed Convenience

Lens choice defines not just image aesthetics but also versatility.

The Sigma fp accepts Leica L mount lenses - today around 30 available lenses ranging from primes to high-quality zooms. This allows for creative flexibility - from ultra-wide landscapes to speedy fast-aperture portraits to macro shoots. Sigma itself offers excellent options and the mount is shared with Panasonic and Leica, widening lens access.

The Sony WX80 has a fixed built-in 28-224mm equivalent zoom lens with an aperture of f/3.3 - 8.0. While decent coverage for travel or casual shooting, the slower aperture at the telephoto end and lack of changeable lenses limits creative control.

Burst Rates and Buffering: Shooting Sports and Wildlife

For subjects in motion, frame rate and buffer depth become crucial.

The Sigma fp offers up to 12 fps continuous shooting, with an electronic shutter enabling silent shooting modes (though max speed here isn’t specified). This is respectable for a compact full-frame and makes it usable for moderate action. Buffer sizes are decent but not exceptional; prolonged high-speed bursts may slow down.

Sony WX80 reports 10 fps continuous but lacks advanced AF tracking or phase detection, limiting its practical use for sports or birds in flight.

Video Features: Versatile Enough for Creators?

While the Sigma fp caters to professionals also making video - offering 4K UHD recording at 30p in MOV H.264 with linear PCM audio inputs for external microphones and headphones - making for an all-in-one production tool.

The Sony WX80 can record Full HD 1080p video at 60fps, with basic stereo sound, but no external mic/headphone jacks and no 4K. Its video specs are fine for casual clips but don’t meet professional standards.

Battery Life and Storage

The Sigma fp uses the BP-51 battery, which is somewhat modest in capacity, and while Sigma doesn’t officially list battery life in shots per charge, in practice expect around 200-300 shots with moderate use. It supports UHS-II SD cards, essential for high-bitrate video and rapid shooting.

The Sony WX80’s NP-BN battery is smaller; however, it claims about 240 shots per charge. It supports various memory card formats, including Memory Stick Duo - a little unusual but indicates an older design.
