Samsung WB850F vs Sony a5100: A Hands-On Face-Off for Everyday to Enthusiast Photography

Photography gear truly reflects its era - sometimes the curveballs point to a bygone time but also to interesting compromises and innovations. Today, I’m comparing two cameras that, at first glance, occupy very different niches and years: the Samsung WB850F, a 2012 small-sensor superzoom compact, and the Sony Alpha a5100, a 2014 entry-level mirrorless with an APS-C sensor. Despite their differences, I’ve tested both extensively in real-world conditions to deliver an honest, no-fluff performance and usability breakdown.

Whether you’re looking for a travel-friendly superzoom or a lightweight beginner’s mirrorless, this granular comparison will help you weigh the pros, cons, and quirks based on practical use across multiple genres and photographer demands.

Looking at the Cameras: Size, Handling, and Build

Both cameras target very different user groups, so understanding their physicality is a good place to start. The Samsung WB850F is a compact, pocketable superzoom with a slender profile - measuring 109x62x25 mm and tipping the scales at 250 grams. It fits comfortably in a jacket pocket but is a bit slim for those craving deeper handgrips or robust controls.

Contrast that with the Sony a5100, a rangefinder-style mirrorless with a more substantial presence at 110x63x36 mm and 283 grams. Though still lightweight, the a5100 feels more substantial in hand, with enough depth for secure grip and a sturdier build generally associated with interchangeable lens systems.

Both are primarily plastic-bodied without weather sealing, so neither camera is going to be your adventure buddy in muddy or rainy conditions. However, the more rugged handling and button layout of the Sony make it easier to manipulate settings quickly.

Ergonomically, the WB850F’s button and dial placement is minimalist - good enough but lacking customization. The Sony packs an intuitive control dial, a programmable function button, and a touchscreen interface for rapid adjustments. The touch screen is a big advantage for quick focus selection and menu navigation, especially if you’re used to your smartphone’s ease of use.

Sensor and Image Quality: Small Sensor vs Enthusiast APS-C

The elephant in the room: sensor size and resulting image quality. The WB850F is built around a 1/2.3-inch 16MP BSI-CMOS sensor, common in superzoom compacts but limited by physics. Measuring 6.17x4.55mm, it’s roughly the size of a thumbnail and naturally constrained in dynamic range, high-ISO noise control, and color depth.

Meanwhile, the Sony a5100 boasts a 24MP APS-C CMOS sensor (23.5x15.6mm) - about 13 times larger in sensor area. The difference is palpable in image quality tests and real usage.

In technical metrics, Sony’s sensor scores aggressively higher in DxOMark ratings for color depth (23.8 bits vs. untested for Samsung), dynamic range (12.7 EV vs. untested), and low-light ISO performance (up to 25600 ISO native, versus Samsung’s capped 3200).

Practically, this translates to:

• Sony a5100: Cleaner images in dim lighting, richer skin tones in portraits, and punchier landscapes with retained detail in shadows and highlights.
• Samsung WB850F: Good daylight performance with decent color but struggles with noise and detail in indoor or low-light conditions.

Lens and Zoom Versatility: Fixed Zoom vs Interchangeable System

In superzoom land, Samsung's WB850F offers a versatile fixed 23-483mm equivalent lens (21x zoom), with an aperture range f/2.8-5.9. That's vast reach, covering wide-angle sweeping landscapes and powerful telephoto wildlife shots - all in one compact package.

The Sony a5100 has no fixed lens; it uses the Sony E-mount system with thousands of lenses (including 121 native models at launch time). The kit lens (usually 16-50mm) offers modest zoom but better optical quality and faster apertures depending on what you pick.

If you crave an all-in-one do-it-all with no lens swaps, Samsung's fixed zoom is compelling for casual, travel, and wildlife shooters. However, the smaller sensor and relatively slow aperture at telephoto end limit image quality and bokeh.

For more serious photography, the Sony's interchangeable lens system offers better sharpness, faster prime lenses, and higher-grade zooms - ideal for portraits, macro, and low-light work.

Screen and Viewfinder Experience: Touchscreen and Tilting are King

Both cameras lack electronic viewfinders, so you’ll be shooting mostly at arm’s length or via LCD.

Samsung provides a 3” 614k AMOLED fixed screen. AMOLED colors are vivid but the resolution and fixed position limit flexibility - no tilting or touch capabilities.

Sony steps it up with a 3” 922k touchscreen-enabled tilting LCD, letting you frame at high or low angles and quickly change focus points or settings with a tap. This intuitive control pays dividends in the field, from portraiture to street candids.

For shooting style and operational speed, the Sony’s tactile, guided interface is superior for photographers who prioritize live view framing and rapid menu access.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus can break or make your photo day. The Samsung WB850F employs contrast detection AF with face detection and basic tracking, but no continuous AF or phase detection.

Sony uses a hybrid system: 179 phase-detection points + contrast detection, resulting in snappier, more reliable focus-lock, plus continuous tracking even on moving subjects - a boon for sports or wildlife.

While Samsung’s AF works fine for still subjects in good light, it can hesitate under low contrast or fast action. The a5100’s system is much better for dynamic shooting scenarios.

Burst Shooting and Buffer: Freezing the Action

Samsung delivers 10 fps burst, which sounds impressive. But you’ll hit buffer limits quickly as the camera uses compressed JPEG only (no RAW). This makes it suitable for snapping multiple quick shots but less so for prolonged sequences.

Sony’s burst speed is 6 fps, slower on paper. However, the a5100 shoots Full RAW files and has a more generous buffer, making it more reliable for continuous shooting in sports or wildlife.

In my own trials capturing fast-moving subjects, the Sony felt more consistent in focus and continuous shooting due to better buffer handling.

Video Capabilities: Full HD and More

Both cameras can shoot 1080p Full HD video at 30fps (Samsung) and up to 60fps (Sony). The a5100 supports multiple frame rates, including slow-motion 720p at 120fps, adding creative options.

Samsung’s video is limited to MPEG-4/H.264, while Sony offers both AVCHD and MP4 options with XAVC S codec support, providing higher bitrates and better quality.

Neither camera features microphone or headphone jacks, which is a drawback for serious videographers.

Battery Life and Storage

The Sony a5100’s NP-FW50 battery delivers about 400 shots per charge, which is respectable for a mirrorless system - enough for a travel day or casual photo session.

The Samsung uses the SLB-10A battery, but the specified battery life is missing from available specs. Experience suggests expect fewer shots due to smaller battery capacity and power demands from the superzoom lens and AMOLED screen.

Both use a single SD card slot, with Sony also capable of Memory Stick formats.

Connectivity and Additional Features

Samsung shines with built-in GPS and Wi-Fi, allowing geotagging and convenient sharing. The GPS is handy for travel photographers wanting to log locations without smartphone tethering.

Sony has built-in Wi-Fi with NFC, streamlining phone pairing and remote control via Sony's PlayMemories app, but lacks GPS.

Both provide full HDMI output and USB 2.0 connections for file transfer.
