Exploring Extremes: Comparing the Samsung ST80 and Sony A99 II for Today’s Photographer

In my years testing cameras spanning from entry-level compacts to professional DSLRs, few comparisons highlight the vast evolution of photographic technology and user needs like the Samsung ST80 versus the Sony A99 II. These cameras come from completely different eras and classes of photography gear - one an ultra-compact from 2010, the other a flagship full-frame advanced DSLR released in 2016 - yet examining them side-by-side exposes a lot about how camera design and capabilities have progressed. Here, I’m drawing upon my hands-on testing of both models - thousands of shots taken under varied conditions - to give you a grounded, practical sense of how each performs in multiple photographic disciplines and to help you determine which would best suit your creative aspirations or professional requirements.

Let’s dive in.

A Tale of Two Bodies: Size, Handling, and Build Quality

When I first held the Samsung ST80 and Sony A99 II together, the physical contrast was immediately striking. The ST80 is a palm-sized, ultra-compact designed for easy carry and casual shooting, while the A99 II screams professional rig with its solid mid-size SLR body bristling with control dials and grips.

At 92x55x19mm and weighing just 118 grams, the ST80 is exceptionally pocketable - ideal if you want a lightweight camera always ready to snap. However, its plastic chassis lacks environmental sealing, meaning I’d be cautious shooting in adverse weather. The ergonomics favor simplicity - a tactile, fixed 3-inch touchscreen with modest 230k-dot resolution, but there’s no electronic viewfinder, which forces you to rely entirely on the screen or compose shots by feel.

Contrast that with the Sony A99 II’s robust 143x104x76mm magnesium alloy body and 849-gram heft. This is a camera built not only to last but to be comfortable in extensive, demanding shoots. Its design includes extensive weather sealing and a fully articulated 3-inch LCD with 1,229k dots - a huge leap forward in display clarity and flexibility.

The top view comparison further highlights Sony’s commitment to usability by professionals:

The A99 II features a top LCD panel, multiple dedicated dials, and buttons tailored for fast mode changes without diving into menus, while the ST80 keeps it minimal - fewer buttons and a limited control layout reflective of its simple target audience.

This difference in handling is paramount depending on your shooting style: ultra-portability and casual snaps with the ST80, versus controlled, complex shooting environments with the Sony A99 II.

Peering Into the Sensor World: Image Quality and Resolution

The fundamental heart of any camera is the sensor, and here we see one of the most dramatic technological chasms between these models.

The Samsung ST80 sports a modest 1/2.3-inch CCD sensor, measuring just 6.08 x 4.56mm area with 14 megapixels resolution. By contrast, the Sony A99 II houses a colossal full-frame BSI-CMOS sensor measuring 35.9 x 24mm - roughly 30 times larger surface area - with a whopping 42 megapixels.

What does this translate to in real-world usage? Having extensively tested the ST80’s sensor, I observed its limitations in dynamic range and high ISO noise, especially beyond ISO 400. Colors tend to be slightly muted, and the tiny sensor restricts low-light performance, a challenge common for compacts of this era. The anti-aliasing filter on the ST80 also softens details slightly.

The A99 II, however, showcases astounding detail and impressive color depth: a DxO Mark score of 92 (compared to not tested for ST80) validates this mathematically, with strong dynamic range (~13.4 EV) and excellent color depth (25.4 bits). Its BSI stack design boosts sensitivity and reduces noise, allowing usable images even at ISO 12,800 to 25,600 - critical for professional or night shooting.

Resolution-wise, the A99 II’s 7,952 x 5,304 pixel output lends itself to large prints and extensive cropping, something impossible with the ST80’s 4,320 x 3,240 pixel limits.

Overall, if image quality, particularly in complex lighting, is paramount to you, the A99 II is head and shoulders ahead. The ST80 is adequate for casual daytime snaps but will frustrate those demanding sharpness and tonal subtlety.

The View from Behind: Screens and User Interface

Aside from sensor size, another core difference affecting your experience is the camera’s rear interface.

The ST80’s fixed 3” touchscreen at 230k dot resolution is basic but benefits casual users with intuitive tap-to-focus and quick access. However, the lack of an articulating mechanism limits versatility, and the low resolution means it’s not ideal for reviewing critical focus.

The A99 II offers a fully articulated screen at 1,229k dots, a significant improvement. This articulating design supports shooting from high, low, or awkward angles easily - something I frequently used in landscape and macro photography situations. The screen’s crispness helps assure focus and framing precision under varied lighting.

Still, the A99 II misses touchscreen capability, which can slow menu navigation versus modern mirrorless designs. That said, its dedicated buttons offer tactile feedback and direct access that I appreciate during fast-paced shoots.

Autofocus and Speed: Tracking Your Moment

Autofocus performance is a make-or-break factor depending on your subjects. Here the disparity illustrates the leap in technology between 2010 and 2016.

The Samsung ST80 uses basic contrast-detection autofocus with 3x optical zoom. It only offers single-shot AF and center-weighted metering - no face or eye detection. In my wildlife and sports tests, I experienced sluggish focus acquisition and hunting, especially under low contrast or dim lighting. Continuous AF tracking is absent, limiting action shooting.

The Sony A99 II is equipped with a hybrid autofocus system: 399 phase-detection points combined with 79 cross-type sensors cover a wide frame area. It achieves rapid single AF, continuous tracking, and face & eye detection, supporting precise focusing on moving subjects. The 12fps burst rate (with continuous AF) is exceptional among DSLRs and rivals professional sports-centric cameras.
