Samsung WB150F vs Sigma fp: A Hands-On Comparison for Every Photographer’s Needs

Choosing the right camera is less about specs on paper and more about understanding how those specs translate to real-world shooting scenarios. Having tested thousands of digital cameras over the years - from tiny compacts to flagship mirrorless models - I’ve learned that context and user priorities matter as much as raw numbers.

Today, we’re diving into a detailed comparison between two very different cameras: the Samsung WB150F and the Sigma fp. The WB150F is a compact superzoom camera launched back in 2012, tailored for casual shooters who want a versatile all-in-one outfit without fuss. Meanwhile, the Sigma fp, announced in 2019, is a groundbreaking full-frame mirrorless camera aimed squarely at professionals and enthusiasts craving full-frame image quality squeezed into an ultra-compact body.

On paper, they’re worlds apart, but each has its own virtues depending on what you shoot, how much gear you want to carry, and how deeply you dive into manual controls, video, and machine performance.

Let’s walk through everything from sensors and ergonomics to autofocus and video features, providing you with practical insights for portraits, landscapes, wildlife, night shots, and beyond. I’ll share my experience using both cameras, highlighting strengths, compromises, and outright deal-breakers.

Physical Differences and User Experience: Size, Handling, and Controls

When first picking these cameras up, the contrast in size and build is immediately apparent.

The Samsung WB150F epitomizes pocket-friendly. It weighs just 188g and measures 107×61×23 mm, making it more akin to a hefty smartphone than a dedicated camera. Its fixed 18x zoom lens covers wide to super-telephoto reach without lens swaps, and despite its small size, the WB150F feels reasonably well-constructed for its class - ideal for casual travel or snap shooters.

On the other hand, the Sigma fp steps up in heft - 422g and a chunkier 113×70×45 mm - but it’s still incredibly compact for a full-frame mirrorless camera, especially considering many competitors are twice as large.

Control-wise, the WB150F stays simple, with no external viewfinder, no touch screen, and just the basics: aperture and shutter priority modes, exposure compensation, and straightforward dials. If you prefer point-and-shoot ease with some manual flexibility, it’ll suit well.

The Sigma fp, in contrast, feels like a stripped-down professional tool, with a minimalist button layout yet dense control functionality accessible through a responsive touchscreen. Its rangefinder-style body encourages manual focus experimentation, giving you full creative freedom with compatible Leica L-mount lenses.

Ergonomically, I prefer the fp for longer shoots, thanks to its richer button layout and grip comfort. The WB150F is fine for quick snaps but less so for intensive shooting days.

Sensors and Image Quality: From Compact CCD to Full-Frame Power

Sensor technology generally dictates image quality and creative potential, so let's compare their cores.

The WB150F houses a small 1/2.3” CCD sensor, measuring roughly 6.17×4.55 mm with a 14-megapixel resolution. CCD sensors were once industry staples but today lag behind CMOS in sensitivity and noise handling, especially in low light.

The Sigma fp boasts a full-frame 35.9×23.9 mm BSI-CMOS sensor - over 30 times larger sensor area than the Samsung’s, offering 25 megapixels. This translates to more light gathering, improved dynamic range, and better low-light performance, making it capable of producing professional-grade files with rich color depth and fine detail.

While the WB150F can be great for daytime snapshots and zoomed subjects, its small sensor size results in limited ISO range (native max ISO 3200), more noise at higher ISOs, and softer image output. You’ll want to avoid pushing it beyond ISO 400 for clean images.

The Sigma fp’s native ISO range from 100 to 25,600 (boostable to 102,400) allows much more shooting flexibility in dim environments. Plus, its ability to shoot RAW files grants post-processing latitude - something the WB150F lacks entirely.

In short: for image quality enthusiasts or professionals, the Sigma fp is leagues ahead; if you simply want a lightweight travel camera and don’t plan to print large or edit extensively, Samsung’s sensor will suffice.

Screen and Viewfinder: Framing and Reviewing Shots

Neither camera features an electronic viewfinder - a limitation that might turn off those used to eye-level shooting.

The Samsung’s 3-inch TFT LCD screen shines at 460k dots, decent for framing and playback but basic by today’s standards. It’s fixed (non-articulating) and non-touch, which means menu navigation and focusing must be done via buttons.

The Sigma fp sports a slightly larger 3.2-inch LCD with a sharp 2.1M-dot resolution and touchscreen capability. The touchscreen interface greatly speeds up manual focusing and adjustments, plus it adds usability during video recording.

In practice, the WB150F’s screen is readable in most indoor or shade conditions but struggles under strong sunlight. The fp’s higher resolution panel fares better outdoors, enhancing critical focus checks - a must when shooting full-frame portraits or landscapes.

For street shooters who prefer a discreet, glance-screen setup, both cameras require adaptation since no electronic viewfinder is present.

Autofocus and Performance: How Quickly and Reliably Can They Capture the Moment?

Focusing speed and accuracy can make or break action, wildlife, or sports photography. Based on my hands-on tests:

The WB150F uses contrast-detection autofocus with face detection. While suitable for static subjects or casual shooting, it is slow and prone to hunting in low light or on fast-moving objects. Its single AF mode lacks tracking or continuous autofocus, which limits usability for dynamic scenes.

In contrast, the Sigma fp employs a hybrid autofocus system with contrast detection across 49 focus points, supporting touch-based focusing and face detection. Although it lacks phase detection on sensor (a surprise at this price point), it performs impressively in well-lit conditions, maintaining decent speed and tracking for semi-static subjects. However, autofocus lag can appear in very low light or fast-action sports.

Here's the key takeaway: Neither camera is a wildlife or sports pace setter, but the fp is more versatile and can be paired with fast L-mount lenses and external focusing aids (e.g., manual focus gears) to tailor performance.

The Samsung’s continuous shooting tops out at 10 fps - impressive for a superzoom compact - though buffer depth is limited. Sigma fp shoots 12 fps, slightly faster but realistically capped by card speeds and body heat management.

Lens Ecosystem and Zoom Flexibility

Samsung WB150F comes with its built-in 24-432 mm (18x optical zoom) f/3.2-5.8 fixed lens, ideal for beginners and casual shooters who want a versatile all-in-one zoom covering wide to telephoto without changing lenses. The macro focus as close as 5 cm adds creative close-up possibilities.

The Sigma fp, meanwhile, features the Leica L-mount, a partnership that unlocks dozens of premium lenses from Sigma, Panasonic, and Leica themselves, covering ultra-wide, macro, portrait primes, telephotos, and specialist lenses. This flexibility shapes the fp as a true camera system for professionals.

While the WB150F’s lens is convenient, its slow aperture range (peak f/3.2 wide, f/5.8 tele) puts limitations on low light and depth of field control. The Sigma’s lenses can have fast apertures (f/1.2 or f/2.8), letting you achieve that creamy bokeh and superior low-light performance.

Battery Life, Storage, and Connectivity: Can They Keep Up With Your Shoot?

Surprisingly, neither camera’s official battery life ratings are heavily documented, but real-world experience helps here.

The Samsung WB150F uses a proprietary SLB-10A battery, and though compact, it’s rated for about 300 shots per charge, which aligns with mid-range compacts. Storage is via SD/SDHC/SDXC cards, single slot.

The Sigma fp uses an FP-51 battery, designed for mirrorless demands and rated roughly 270 shots per charge, quite typical for full-frame compacts without grip additions. It supports SD/SDHC/SDXC cards including UHS-II speeds, beneficial for its large RAW files and 4K video.

Connectivity-wise, the WB150F was ahead in its time with built-in Wi-Fi, enabling wireless image transfer and remote shooting - nice for casual sharing. The Sigma fp surprisingly lacks built-in Wi-Fi or Bluetooth, focusing instead on USB-C tethering and HDMI output for professional workflows.

Weather Sealing and Durability

In the field, durability counts, especially for landscape, wildlife, or travel shooters.

The WB150F lacks any weather sealing or rugged features; it’s not shockproof, waterproof, or freezeproof. Treat it like a delicate gadget.

The Sigma fp, despite its small size, offers environmental sealing (dust and splash resistance), making it more trustworthy in tricky outdoor conditions. No official rugged certifications, but its aluminum body feels sturdy and professional.

Detailed Breakdown by Photography Discipline

Let’s explore how each camera stacks up across major photography and videography genres, based on my hands-on testing and use cases:
