First Impressions: Size, Handling, and Design Compared

The WB850F and Sony TX20 cater to compact photography, but their footprint and ergonomics are quite distinct.

The Samsung WB850F is in the Small Sensor Superzoom category, giving it a larger body to accommodate an impressive 21× zoom lens - far-reaching for such a portable device. By contrast, the Sony TX20 falls into the Ultracompact class, favoring pocketability and sleekness with a modest 4× zoom lens.

Examining the dimensions:

• Samsung WB850F: 109 × 62 × 25 mm, weighing 250g
• Sony TX20: 96 × 56 × 18 mm, weighing 133g

The WB850F feels sturdier in hand thanks to its heft while the TX20 can easily slip into a coat pocket or small purse.

Moving to the control layout, both have user-friendly designs but with different focal points. The WB850F’s larger body naturally allows for bigger buttons and a more traditional camera grip, while the TX20 uses a minimalist control scheme benefitting from its ultracompact size.

Personally, I found the WB850F’s dedicated mode dial and buttons more intuitive for quick adjustments, especially shooting in manual or semi-manual modes. The TX20’s touchscreen interface (absent on the WB850F) is a double-edged sword: convenient for some users but less tactile and slower for quick setting tweaks during dynamic shooting.

Summing up Ergonomics:

• WB850F suits users valuing control and substantial zoom reach, preferring a more traditional handling experience.
• TX20 appeals to photographers prioritizing ultra-portability and a touchscreen interface, at the expense of advanced manual control.

Sensor and Image Quality: Peering Beneath the Surface

Both cameras share the same sensor size - 1/2.3-inch BSI CMOS sensors measuring 6.17 x 4.55mm with a 16MP resolution (4608 x 3456 pixels). This size is typical among compact models but significantly smaller than the APS-C or full-frame sensors favored by advanced photographers.

Because of identical sensor dimensions and pixel count, inherent dynamic range and noise performance have a similar baseline, though software and processor implementation play a role.

Samsung WB850F Specs:

• Max ISO: 3200
• Sensor technology: BSI CMOS
• RAW support: No (JPEG only)

Sony TX20 Specs:

• Max ISO: 3200
• Sensor technology: BSI CMOS
• RAW support: No (JPEG only)

Neither camera supports RAW capture, a limiting factor for enthusiasts keen on extensive post-processing flexibility.

Through side-by-side testing with identical scenes - balanced lighting, indoor low light, and colorful landscapes - I noticed slight differences attributed to image processing. Sony’s BIONZ processor and TruBlack display yield marginally more vibrant colors and cleaner JPEG noise suppression in low light. Samsung’s images, meanwhile, show good sharpness and contrast but tend to produce slightly warmer skin tones, which could be preferred for portraiture.

In practical terms:

• Both cameras perform adequately for casual and travel photography, providing 16MP detail sufficient for prints up to A3 size.
• Neither excels in dynamic range, so preserving highlight and shadow detail requires careful exposure control.
• Noise becomes visible as ISO approaches 1600+ but this is expected at this sensor size.

Display and User Interface: Where Samsung and Sony Diverge

LCD quality and user interface greatly affect shooting experience, especially for composing shots and navigating menus in compact cameras.

The Samsung WB850F sports a 3-inch AMOLED fixed display with a resolution of 614k dots, offering vivid colors and excellent contrast. However, its non-touchscreen design means navigation relies on buttons and a four-way controller.

The Sony TX20’s 3-inch XtraFine TruBlack TFT LCD offers 922k dots and includes touchscreen capabilities, enhancing focus selection and menu navigation fluidity.

From hands-on tests:

• The Samsung’s AMOLED excels in bright conditions, showing rich blacks and impressive visibility outdoors.
• Sony’s higher-resolution screen is sharper but can reflect ambient light, reducing visibility under harsh sun. The touchscreen is responsive and supports focus area selection and accessing quick settings with a tap - great for street photographers aiming for speed and subtlety.

Takeaway for UI:

• Samsung WB850F is better for those comfortable with physical controls preferring a bright, punchy display.
• Sony TX20 suits users who favor touch interaction and higher resolution at a minor cost to outdoor visibility.

Autofocus and Shooting Performance: Speed and Accuracy under Pressure

Autofocus (AF) speed and accuracy are critical in genres like wildlife, sports, and street photography.

Both cameras employ contrast-detection autofocus systems with face detection capabilities.

• Samsung WB850F offers single, tracking, selective, and center AF modes with face detection.
• Sony TX20 also supports face detection and a touch-to-focus feature enabled via touchscreen.

Continuous autofocus isn’t supported on either; both rely on AF lock and single AF modes during shooting.

In controlled burst shooting tests:

• Both hit 10fps burst shooting at full resolution, adequate for casual action snaps but limited for professional sports.
• Samsung’s larger lens and zoom range mean AF sometimes hunts slightly longer at max zoom but compensate with decent tracking in good light.
• Sony’s AF is snappy in bright conditions but slows noticeably under low light or close macro scenarios.

Macro focusing is a particular strength of the TX20, focusing as close as 1cm compared to WB850F’s 5cm minimum focus distance - a noticeable advantage for close-up enthusiasts.

Lens and Zoom Capabilities: Reaching Beyond the Frame

Arguably, the biggest hardware difference: zoom range.

• Samsung WB850F: 23-483mm equivalent (21× optical zoom, f/2.8-5.9 aperture)
• Sony TX20: 25-100mm equivalent (4× optical zoom, f/3.5-4.6 aperture)
