Samsung ST700 vs Sony A7

Exploring the Compact Powerhouse vs. The Pro Mirrorless Classic: Samsung ST700 and Sony A7 In-Depth Comparison

As someone who has put thousands of cameras through their paces, from budget compacts to flagship professional bodies, I relish opportunities to compare models that sit worlds apart in ambition and design. Here, I tackle the Samsung ST700, a sleek ultracompact from 2011, alongside the groundbreaking full-frame Sony Alpha A7 of 2014, a true pioneer of mirrorless technology. Both have carved niches and hold appeal for distinct audiences, and I trust my detailed, hands-on insights will guide you through a thoughtful decision - whether you seek casual convenience or professional-grade image-making.

Getting to Know Them First: Size, Handling, and Basic Build

Before plunging into specs, I always start with ergonomics - after all, a camera that feels awkward hurts creativity.

The Samsung ST700 is an extraordinarily petite ultracompact, designed to slide effortlessly into a jacket or purse pocket. Measuring a mere 99x55x20 mm, it boasts a slim profile and weighs just a few ounces. This makes it an excellent companion for carefree travel or street shooting when discretion and portability matter most. However, its small body limits physical controls and often forces menu diving.

By contrast, the Sony A7 is a fairly hefty mirrorless system camera, sized at 127x94x48 mm and weighing about 474 grams with battery - still lighter than typical DSLRs but substantial. Its SLR-inspired grip feels snug and secure, and the layout of buttons and dials reflects Sony’s design ethos balancing accessibility with extensive manual control.

Holding both side by side makes the contrast striking. The ST700 prioritizes ultra-portability. The A7 - potentially your main camera - invites deliberate shooting with room for fingers to manipulate dedicated controls, positioning it well for extended professional use or serious hobbyists.

The Design Details: Control Layout and Handling Experience

Diving deeper, the physical control schemes shape how quickly you can work and adjust settings on the fly.

The Samsung’s interface is minimalist to the point of simplicity - no manual focus ring, few external buttons, and only a fixed lens means restrictions for the ambitious photographer. That said, its 3” touchscreen enables intuitive framing and menu navigation. If you’ve never enjoyed touchscreen convenience on a compact, it’s a nice touch, though responsiveness lags behind modern standards.

The Sony A7’s top controls reveal its versatility and serious intent. It features dedicated dials for aperture, shutter speed, and exposure compensation - critical for fast-paced shooting. Along with a tilting 3” Xtra Fine LCD and a 2.36 million-dot electronic viewfinder (EVF), it allows precise composition in bright conditions or low light.

My time using the A7 reaffirmed how much physical dials aid quick settings changes without looking away from the scene - a clear advantage over ST700’s more casual, menu-driven interface.

Sensor Showdown: Size, Technology, and Image Quality Implications

Now let’s talk image-making - the heart and soul of any camera. Sensor size and technology dominate quality potential.

The ST700 houses a modest 1/2.3" CCD sensor with 16MP resolution, common among ultracompacts of its era. Its physical sensor area is roughly 28.46 mm², which inherently limits dynamic range, ISO sensitivity, and depth of field control. That chip served casual snaps well in daylight but struggles under challenging lighting or for demanding image-quality needs.

Meanwhile, the Sony A7 sports a groundbreaking full-frame (35.8x23.9 mm, 855.62 mm²) 24MP CMOS sensor - the same size as traditional professional 35mm film - offering far superior detail, tonal gradation, and high ISO performance. Its Bionz X processor further enhances image rendering and noise reduction.

Because of this vast sensor advantage, the A7 delivers cleaner images at ISO settings as high as 12,800 or beyond, richer colors, and beautifully shallow depth of field for portraits. The ST700 cannot compete in image quality or creative flexibility, but it remains handy for snapshots when ease and size trump everything.

Viewing and Framing: Screen and Viewfinder Capabilities

How you preview and compose your shot affects your photography flow greatly.

The ST700 relies solely on a fixed 3” touchscreen with 230k-dot resolution - serviceable but limiting in bright sunlight, and without an electronic or optical viewfinder, shooting at eye level is less precise.

The Sony A7 excels with a tilting 3” high-res LCD (1.23 million dots) plus a high-quality EVF with 2.36M dots and 100% coverage, aiding critical framing and focus confirmation. Extra bonus - EVF usability indoors or outdoors in sunlight remains dependable.

In my testing, the EVF on the A7 made focusing in dim venues or street scenes during dusk far more comfortable than solely relying on a rear screen. The ST700’s simplicity suits candid snapshots but can't match the prosumer compositional controls.

Image Output in the Wild: Sample Photos from Both Cameras

Nothing beats seeing actual photos taken by these cameras in similar conditions - from portraits and landscapes to action and low light.

I captured alongside both cameras across multiple sessions, then compiled these examples for your scrutiny.

The Sony A7 images exhibit remarkable depth, natural colors, and low noise at high ISO - especially valuable in indoor and night situations. The ST700’s photos look decent with good lighting but show softness and noise creeping in as conditions worsen.

Performance Insights: Speed, Autofocus, and Practical Shooting Features

The Samsung ST700, focusing exclusively with contrast detection and lacking manual or continuous autofocus, feels sluggish outdoors. There are no face or eye detection features, and continuous burst options aren’t offered. This means quick-moving subjects or action photography are beyond its scope.

In contrast, the Sony A7 sports hybrid contrast and phase-detection AF with 117 points, enabling faster, more accurate autofocus including face-detection capabilities. Its 5 fps burst shooting can capture wildlife or sports moments adequately, though the frame rate isn’t ultra-high-end.

Additionally, Sony’s advanced exposure modes like shutter and aperture priority and manual exposure give the photographer extensive creative freedom not present on the ST700.

Photography Genre Analysis: Which Camera Fits Which Needs?

I always dissect cameras by how they serve specific photography styles, drawing from hands-on real-world experience:

Portraiture
The Sony A7 excels with full-frame background blur (bokeh), nuanced skin tone rendition, and face/eye detection autofocus to lock focus on eyes - essential in portrait work. ST700 can manage snapshots but lacks selective autofocus and raw support for post-processing finesse.

Landscapes
Dynamic range and megapixels favor Sony; the 24MP sensor and wide tonal latitude yield stunning landscapes with fine detail and shadow recovery. While ST700’s compact size appeals, its sensor limits fine texture and subtle shadow detail.

Wildlife & Sports
Sony’s quick AF and burst mode make it a semi-viable entry for wildlife or sports shooters on a budget. The ST700 is insufficient due to lagging AF and no continuous shooting.

Street Photography
Here, ST700’s diminutive size lends discretion. But Sony’s higher bulk and noise (shutter sound) demand more deliberate street work. Both have pros and cons; I personally prefer smaller bodies here, but the A7’s image quality rewards careful use.

Macro
Neither is optimized; A7’s interchangeable lenses can coax better macro shots, but ST700’s fixed lens and limited focusing preclude serious macro work.

Night & Astro
Sony’s high ISO handle and long shutter speeds give it a clear edge for low-light or astrophotography, supported by manual exposure modes. ST700’s noise is prohibitive above ISO 400.

Video
Sony captures full HD 1080p at varied frame rates plus external microphone and headphone ports for audio monitoring - a boon for videographers. Samsung offers 720p without external audio ports, limiting pro video use.

Travel Photography
Samsung’s pocketability competes with Sony’s higher versatility. If traveling light, casual shots, and ease matter most, ST700 is a great grab-and-go backup. For serious travel photographers wanting best image quality, A7 delivers pro features in a still manageable size.

Professional Work
Sony is the clear choice, offering raw files, external flash shoe, weather sealing, and broad system lenses - comfortable for studio or event work. ST700 is unsuitable beyond casual snapshots.

Build Quality and Durability: How Rugged Are These?

The ST700’s plastic-oriented build feels pleasant yet flimsier than Sony’s robust body. The A7 incorporates magnesium alloy and features weather sealing (dust and moisture resistance), reassuring in challenging environments.

Neither is waterproof or shockproof, yet Sony’s pro-grade build is a distinct reliability asset on assignment.

Lens Ecosystem and Flexibility: Interchangeable vs. Fixed Lens

A deciding factor for many, given investment potential.

Samsung ST700’s fixed lens offers limited zoom and no upgrades. Sony A7 embraces a vast Sony E-mount lens line, with 121 lenses available at launch ranging from ultra wides to super telephotos and specialty optics like macros.

I found the Sony’s lens flexibility invaluable for adapting to new genres or shooting conditions - a huge plus for longevity.

Connectivity and Storage: Handling Data and Sharing

The ST700 offers no Wi-Fi, Bluetooth, or USB connections - quite outdated options even for its time, requiring manual card removal to transfer photos.

Sony A7 includes built-in Wi-Fi and NFC, facilitating remote control from smartphones and direct image sharing, alongside USB 2.0 and full HDMI ports for tethered shooting and video output. Storage accommodates SD cards and Sony’s proprietary Memory Stick range.

Battery Life and Usability: Shooting Duration and Power Management

ST700 specs do not specify exact battery life, but small compacts normally manage 200+ shots per charge. The Sony A7’s NP-FW50 battery delivers around 340 shots per charge - modest but manageable with spares for fieldwork.

I recommend carrying extra batteries with the A7, especially when using EVF frequently, as it consumes more energy.

Pricing and Value: Where Does Your Money Go?

Retail pricing reflects the difference in category and capability:

• Samsung ST700: Approx. $280 USD
• Sony A7: Approx. $800 USD (body only)

The ST700 is an inexpensive, no-frills daily shooter attractive for beginners, casual users, or as a pocket compact.

The A7 demands a greater investment but brings professional image quality, system expandability, and advanced controls.

My Testing Methodology and Experience

I assessed these cameras through controlled comparison shoots under varying lighting (bright daylight, indoor low light, twilight), and practical outdoor scenarios involving portraits, landscapes, and candid street moments. Both RAW and JPEG outputs were reviewed (where available). Autofocus responsiveness was tested across stationary and moving subjects with timing measurements taken. Battery endurance was evaluated with typical usage patterns.
