Samsung EX2F vs Sony A77 II: A Hands-On Expert Comparison for the Practical Photographer

Choosing a camera can feel like stepping into a minefield of specs, reviews, and marketing fluff. Having tested thousands of cameras over the past 15 years, I know it boils down to understanding how a camera performs in real-world situations - not just what its billboard numbers say. Today, I’m putting two fairly different but still often compared cameras through their paces: the compact Samsung EX2F and the advanced mid-size Sony A77 II DSLR. Both have solid reputations but cater to distinct audiences and uses.

I’ll walk you through everything: sensor tech, ergonomics, autofocus, image quality, and how they hold up across key photographic genres, from portraits and landscapes to wildlife and video. Along the way, I’ll share my personal take on their strengths, weak points, and - most importantly - the types of photographers who’ll get the most from each one. Let’s dive in.

Seeing Eye-to-Eye: Size, Build, and Handling

The Samsung EX2F is a compact through and through - a pocketable travel companion. At just 112 x 62 x 29 mm and weighing a mere 294 grams, it feels feather-light in the hand. The Sony A77 II, meanwhile, is a mid-size DSLR, more comparable to what you’d expect from a traditional camera with clubs for your thumbs: 143 x 104 x 81 mm and tipping the scales at 647 grams.

Holding the EX2F feels nimble and casual - ideal if you hate lugging gear but want better image quality than your smartphone. Its fixed lens, compact silhouette, and minimalist controls make quick shooting simple, though prolonged sessions can strain the fingers a bit due to its compact grip. Conversely, the A77 II’s heft and pronounced grip offer exceptional ergonomics for longer shoots, with dedicated dials and buttons laid out for speedy adjustments without diving into menus - a boon for action photographers or anyone who shoots seriously.

On top, the Sony shows more robust physical controls and a secondary top screen, helpful for glance-checking settings - a feature absent on the EX2F.

Bottom line: if portability and discretion are paramount, the Samsung edges ahead. If you want handling tailored for heavy-duty shooting, the Sony wins hands down.

Sensor Showdown: Larger, Sharper, or Just What You Need?

At the heart of any camera lies its sensor, and this is one of the most fundamental divides between these two models.

The Samsung EX2F uses a 1/1.7” BSI-CMOS sensor (about 7.44 x 5.58 mm, 12 MP). This sensor punches above what many other compacts offer, aided by a bright F1.4 aperture at the wide end. However, it still falls short compared to the Sony A77 II’s much larger APS-C CMOS sensor (23.5 x 15.6 mm, 24 MP).

How does that translate into images? From a technical perspective:

• Dynamic Range: The Sony pulls ahead comfortably with 13.4 stops of dynamic range versus Samsung’s 11.5 stops - important for landscape and high-contrast scenes.
• Color Depth: The A77 II’s sensor captures richer, more nuanced colors (24.4 bits versus 20 bits).
• Low-Light Performance: While the Samsung can shoot at ISO 3200 max, its performance at high ISO is moderate (DxOMark low-light score 209). The Sony pushes to ISO 25600 native, with excellent noise control above ISO 1000.
• Resolution: 24 MP on the Sony vs 12 MP on the Samsung translates to more detailed images, especially evident for large prints or heavy cropping.

From extensive testing in varied light, I can confirm that the Sony’s sensor delivers cleaner, sharper, and more versatile images, particularly if you shoot RAW (both cameras support RAW capture). The Samsung’s sensor is solid for its class but best reserved for casual or travel photography where convenience trumps ultimate image excellence.

The Vital Organ: Autofocus Systems in Daylight and Action

Autofocus technology is a clear battlefield between these two cameras:

• The Samsung EX2F uses contrast-detection autofocus exclusively, with little by way of advanced tracking or multiple AF points. It lacks face and eye detection, continuous AF, and doesn’t offer multi-area AF modes. For static subjects and controlled lighting, it works well enough, but miss the mark under dynamic conditions.

• The Sony A77 II is built for speed and precision, leveraging a hybrid AF system combining 79 phase-detection AF points (15 cross-type), plus contrast detection for refining focus in live view. It incorporates face detection, continuous AF for moving subjects, and AF tracking - all crunching on the fast Bionz X processor.

Such specs translate into very different real-world experiences:

• For portrait work, Sony’s eye detection and tracking capabilities consistently nail focus on the eye with minimal hunting.
• For wildlife and sports, the 12fps burst rate combined with sophisticated AF tracking is a game changer - allowing you to grab sharp images of fast-moving animals or players.
• Samsung’s slower AF and lack of tracking mean you’ll struggle with moving subjects; it suits well-lit, static shooting scenarios.

Viewing and Composing: Screens and Viewfinders

How you frame your shot - the screen and viewfinder - is critical for a satisfying shoot.

Both cameras offer a fully articulating 3" screen, but the Samsung goes AMOLED, providing punchy colors and deep blacks, though screen resolution specifics are less clear, likely around the lower end. The Sony’s screen is sharper (1229k dots), but not AMOLED, giving a more natural but less saturated preview.

When it comes to viewfinders, they’re quite different beasts:

• Samsung offers an optional electronic viewfinder, but none built in. You’ll mostly rely on the rear screen.
• Sony’s A77 II has a high-quality electronic viewfinder with 2.35 million dots, 100% coverage, and 0.73x magnification - a treat for manual focus and shooting in bright conditions.

The advantage of a great EVF can’t be overstated, particularly for precision framing and critical focusing, something serious hobbyists and pros crave.

Image Quality in Focus: Real Photos and Image File Types

Specs are great, but seeing is believing. Both cameras shoot RAW and JPEG, giving you editing flexibility or out-of-camera convenience.

The Samsung’s images show good contrast and vibrant colors straight from the camera, benefiting from a bright lens (F1.4) that gives attractive background blur (bokeh) for a fixed lens compact. However, due to the smaller sensor and older processor, images get noisy above ISO 800, and detail softens quickly with aggressive sharpening often needed.

The Sony excels here, delivering highly detailed textures and rich tones with impressively clean shadows and highlights retention. In daylight portraits, skin tones look natural, and bokeh is smooth and controlled with native Sony glass.

Overall, the Sony’s superior sensor and processing pipeline yield images that stand tall against modern mirrorless and DSLR competitors.
