Samsung ST150F vs Sony A35: A Deep-Dive Comparison to Guide Your Next Camera Purchase

In the ever-evolving world of digital photography, choosing the right camera can often feel like navigating a minefield of specifications, marketing buzz, and personal preferences. Today, we’re tackling a thorough comparison between two particularly different cameras, each designed with distinct photography philosophies in mind: the Samsung ST150F, a small sensor compact from 2013, and the Sony SLT-A35, an entry-level DSLR-style hybrid camera from 2011.

Having logged hundreds of hours testing cameras across genres, from macro to sports, I aim to give you a grounded and honest assessment based not just on specs but on hands-on experience. Whether you’re a casual snapshooter or someone considering a reliable backup or beginner-friendly system, you’ll find this comparison valuable.

Physical Presence & Ergonomics: Compact Convenience vs DSLR Handling

First impressions stick, and the physical dimensions and handling play a crucial role in your day-to-day shooting experience.

The Samsung ST150F is a compact camera engineered primarily for portability and ease. Weighing just 114 grams and sized at 94 x 58 x 18 mm, it’s exceptionally pocket-friendly. Holding this camera, you immediately sense its lightness, making it ideal for quick trips where carrying gear feels like a burden.

By contrast, the Sony A35 tips the scales at 415 grams with a bulkier footprint of 124 x 92 x 85 mm. It offers the more substantial grip and tactile controls you expect from a DSLR-style body. This build provides a solid handhold, better balance with larger lenses, and generally improved handling for extended shooting sessions. Especially useful for advanced users accustomed to precise button layouts, its ergonomics inspire confidence when tracking fast action or working in challenging scenarios.

Looking at the top control layout accentuates these design philosophies: the Sony boasts a dedicated mode dial, exposure compensation dial, and multiple buttons configurable for quick access. The Samsung simplifies with minimal physical buttons, prioritizing an uncluttered user interface for casual users.

Practical takeaway: If pocketability and spontaneous shooting top your priority list, the Samsung’s diminutive size wins. However, for more control, better grip, and ergonomic refinement, the Sony’s DSLR-style body is the superior choice.

Sensor Technology & Image Quality: CCD vs CMOS with a Generational Gap

Understanding sensor design and size is critical for evaluating image quality, dynamic range, and low-light performance. Here, the two cameras couldn’t be more different.

The Samsung ST150F features a 1/2.3-inch CCD sensor measuring approximately 6.17 x 4.55 mm (28 mm² area) with 16 megapixels resolution. CCD sensors, especially in compact cameras, are known for decent color reproduction but generally fall short in noise control and dynamic range compared to more modern CMOS designs.

On the other hand, the Sony A35 employs a significantly larger APS-C sized CMOS sensor (23.5 x 15.6 mm, or ~367 mm²) at 16 megapixels, the same nominal resolution but with a sensor surface area over 13 times larger than the Samsung. This provides a huge advantage in gathering light, delivering cleaner images at high ISO, richer color depth (23.3-bit color depth), and exceptional dynamic range (12.7 EV) tested by our industry-standard DXOMark metrics.

The larger sensor surface area of the Sony also means shallower depth of field control, essential for portrait and macro photography, allowing more professional aesthetic flexibility that the Samsung’s compact sensor simply cannot match.

Real-world implications: In bright conditions, the Samsung can produce pleasing snaps suitable for social media and casual prints, but in low light or demanding scenes requiring tonal nuance, the Sony’s APS-C CMOS sensor easily outpaces it.

Viewing & Interface: From Basic LCD to Electronic Viewfinder

Viewing your composition and reviewing images come down to the quality and usability of displays and viewfinders.

The Samsung’s 3-inch QVGA TFT LCD offers a resolution of just 230k dots, which - frankly - is quite low by today’s standards. This leads to grainy previews and a fairly limited dynamic range on the screen itself, making it difficult to judge exposure accurately.

In contrast, Sony’s A35 offers a 3-inch LCD with 921k dots - a vastly superior screen that renders images sharply. Furthermore, it includes a refreshingly clear electronic viewfinder (EVF) with 1150k-dot resolution and 100% field coverage with 0.73x magnification. For any photographer aiming for precision framing, an EVF is a game-changer - outperforming the “blind shooting” that occurs only with LCDs on compacts.

Another practical aspect is control feedback. The A35 features an intuitive menu system tailored for manual exposure modes, focus adjustments, and playback review, all accessible through a well-considered button layout, whereas the Samsung’s fixed-lens approach and simplified menu limit creative control.

Autofocus & Speed: The Differing Demands of Contrast Detection vs Phase Detection

Autofocus (AF) responsiveness is critical, especially for subjects in motion and tricky lighting conditions.

The Samsung ST150F uses contrast-detection autofocus only - a system typically slower and less reliable when tracking moving subjects. Face detection is supported, which can enhance portrait results somewhat, but there’s no continuous AF or tracking mode for action.

The Sony A35 takes a hybrid approach using Sony’s Translucent Mirror Technology (SLT) with 15 phase-detection AF points, three of which are cross-type for increased precision. This system excels at both single-shot focus and continuous AF modes (up to 6 fps shooting), ideal for wildlife, sports, and fast-paced street photography. One caveat is that the A35’s AF tracking isn’t as advanced as newer models and may require manual intervention under certain conditions, but it’s still far superior to the Samsung’s approach.

In the field: I found the Sony A35 autofocus brisk and dependable when paired with good glass, ensuring confident focus on eyes and moving subjects; the Samsung, however, struggles beyond simple scenes - resulting in many missed focus opportunities.

Lens Systems and Expandability: Fixed Zoom vs Interchangeable Freedom

A camera system’s lens ecosystem dramatically impacts versatility and creative potential over time.

The Samsung ST150F’s lens is fixed, offering a 25-125mm (35mm equivalent) 5x zoom with a maximum aperture ranging from f/2.5 to f/6.3. While the optical zoom covers useful focal lengths for everyday photography, the lack of lens interchangeability or adaptability is a clear constraint for enthusiasts interested in specialized genres such as macro or telephoto wildlife.

Conversely, the Sony A35’s lens mount accommodates the extensive Sony/Minolta Alpha lineup - over 140 lenses at last count. You get a huge range from prime lenses for portraits with stunning bokeh to telephotos for sports and wildlife, plus manual focus and third-party glass compatibility. This adaptability makes the A35 a far more flexible investment since you can tailor your setup to specific photographic challenges.

Battery Life and Storage: What Powers Your Shoot?

Battery life can often be the deciding factor for serious users who shoot for long hours or travel extensively.

The Samsung ST150F does not specify battery life clearly, but compact cameras of this class typically handle about 200-300 shots per charge, often powered by proprietary batteries with modest capacity.

Sony A35 shines here markedly with a rated 440 shots per charge, supported by the NP-FW50 battery pack - a well-known standard used across Sony mirrorless and DSLR-like models. This reliability is valuable for day-long shooting or events. The battery compartment and power management on the Sony are designed for quick swapping and longevity.

Storage-wise, the Samsung uses microSD cards with one slot, while the Sony offers a single slot compatible with SD/SDHC/SDXC and Memory Stick Pro formats, a slight advantage for professional workflows aiming for speed and capacity.
