Sony A7S II vs Sony W290: A Comprehensive Camera Comparison for Enthusiasts and Pros

Photography gear is an intensely personal choice. Behind each brand and model lies a unique blend of technology, usability, and creative potential. Today, I’m diving deep into two cameras from Sony that could not be more different: the Sony Alpha A7S II, a professional full-frame mirrorless powerhouse launched in 2015, and the Sony Cyber-shot DSC W290, a beginner-friendly compact from 2009 that fits easily into a pocket. My goal is to go beyond specs and marketing blurbs - to share detailed insights drawn from years of personal hands-on testing, lab evaluations, and practical field shooting.

Whether you’re contemplating an upgrade to pro-level video and low-light capabilities or looking for a simple step-up point-and-shoot, this comparison will help you understand precisely which camera suits your style, workflow, and budget.

Size and Handling: Pocketable Convenience vs. Pro-grade Ergonomics

The Sony A7S II is designed for serious creators who demand versatility and control without the bulk of a DSLR. Its SLR-style mirrorless body weighs in at 627 grams and measures 127 x 96 x 60 mm. In contrast, the tiny Sony W290 tips the scales at only 167 grams with a compact profile of 98 x 57 x 23 mm - making it ideal for casual shooters or travel photographers needing a hassle-free companion.

Ergonomics:
The A7S II impresses with its solid magnesium alloy frame and weather sealing, lending confidence for outdoor and challenging conditions. Its grip is pronounced and comfortable for extended handheld use. The W290, hardly more than a point-and-shoot, offers minimal physical controls and a plastic body, which sacrifices durability but benefits true portability.

If you prize handheld stability and a tactile shooting experience, the A7S II is head and shoulders above. But for those who value absolute compactness and snap-quick shooting, the W290 remains a viable lightweight option.

Controls and Interface: Complexity vs Simplicity

The A7S II sports an impressive array of dials, customizable buttons, and a mode dial, enabling rapid access to shutter speed, ISO, aperture priority, exposure compensation, and more. I’ve always found its control layout thoughtfully designed, with a top LCD screen for quick settings reference - a blessing in fast-paced environments.

Conversely, the W290’s control scheme is barebones, relying on basic mode selections and limited manual override. This simplicity is fine for casual day-to-day photography but will frustrate anyone seeking fine control over exposure or lens options.

In practice, the A7S II allows intuitive manual shooting and experimentation, critical for professional portraits, landscapes, or video work. The W290 encourages automatic shooting, which suits beginners but limits creative flexibility.

Sensor Technology and Image Quality: Full-frame Brilliance vs Small Sensor Convenience

Arguably the most important distinction: sensor size and technology.

• Sony A7S II: Boasts a full-frame 12.2MP Exmor CMOS sensor measuring 35.6 x 23.8 mm with remarkable light-gathering ability.
• Sony W290: Compact 1/2.3-inch (6.17 x 4.55 mm) CCD sensor with 12MP resolution.

This difference in sensor area (847 mm² vs 28 mm²) profoundly impacts image quality and performance:

• Dynamic Range: The A7S II provides around 13.3 stops of dynamic range, excellent for preserving detail in shadows and highlights - a must for landscapes and high-contrast scenes. The W290’s small sensor struggles noticeably here.
• Low-light Performance: The A7S II excels with a native ISO range from 100 to 102,400 and a boosted mode up to 409,600 ISO. Its low-light ISO performance score is an outstanding 2993 (DxOMark), meaning clean, usable images in near-darkness. The W290 maxes out at ISO 3200 with more noticeable noise.
• Resolution and Detail: Both cameras offer roughly 12-megapixel resolution. However, the A7S II’s sensor produces sharper, clearer images due to larger photosites and better signal processing despite lower pixel count compared to modern high-res cameras.

I extensively tested both on a tripod in daylight and dim interiors. The A7S II’s full-frame sensor grants superior clarity, color depth, and noise control, allowing for more latitude in post-processing. The W290 is fine for casual sharing but quickly hits quality ceilings in demanding conditions.

Display and Viewfinder: Viewing Experience Matters

• A7S II: A 3-inch tilting LCD with 1.2 million dots and a 2.36M-dot electronic viewfinder (EVF) offering 0.78x magnification and 100% frame coverage.
• W290: A fixed 3-inch LCD with just 230k dots, no EVF.

The A7S II’s EVF provides real-time exposure previews and sharp framing, invaluable for critical compositions, especially in bright daylight where rear LCDs struggle. The tilting screen is a boon for creative angles and video shooting.

Meanwhile, the W290 relies solely on its modest LCD, which is often hard to see in direct sunlight. The lack of EVF limits precision framing and stability, especially for longer focal lengths.

For photographers keen on accurate focus and composition control, the A7S II’s high-res OVF and flexible LCD are must-haves.

Autofocus Systems: Precision vs Simplicity

The A7S II features a 169-point contrast-detection AF system without phase detection points. While not the latest hybrid AF, this system proved remarkably effective during my continuous autofocus and subject tracking tests, especially in video mode. It includes face detection, eye autofocus, and multiple AF area modes, enabling accurate tracking in portrait and event photography.

The W290 sports a very basic 9-point contrast only AF, center-weighted, suitable for static subjects but prone to hunting and focus lag in low light or moving scenes.

In practical use:
The A7S II’s autofocus, though older by modern standards, supports professional workflows with speed and reliability. The W290 functions adequately for snapshots but cannot compete where sharpness under motion is required.

Lens Ecosystem Flexibility

• A7S II supports Sony’s E-mount lenses with an extraordinary range: over 120 native lenses, from fast primes and robust telephotos to specialty glass like macro and cinema lenses.
• The W290 has a built-in fixed zoom (28-140mm equiv.), non-interchangeable.

For pro or enthusiast photographers, the ability to choose and switch lenses is invaluable. I’ve used everything from ultra-wide-angle to 400mm telephotos on the A7S II for diverse shooting, an immense creative advantage. The W290 is limited to its onboard zoom, fine for casual but restrictive for serious work.

Real-World Shooting Across Genres

Portrait Photography

A7S II:
The large sensor and excellent color depth capture natural skin tones with smooth gradation. Its 5-axis in-body stabilization (IBIS) aids sharp handheld shots, and eye-detection AF (though limited compared to newer models) helps maintain critical focus. The bokeh from fast Sony primes is creamy and aesthetically pleasing.

W290:
Portraits are soft with less background separation due to the small sensor and slow lens aperture (f/3.3-5.2). Skin tones tend to be flatter, and low-light indoor shots suffer noise and blur.

Landscape Photography

The A7S II’s dynamic range and weather sealing make it reliable outdoors. Paired with a high-quality wide-angle lens, it resolves textures superbly even in challenging light. I’ve captured scenes with rich color transitions and deep shadows far beyond the W290’s capabilities.

The W290 can capture decent landscapes on sunny days but is best for casual use.

Wildlife and Sports Photography

While the A7S II’s AF is good, its 5 fps continuous burst speed is moderate compared to dedicated sports cameras. However, in low light and with its compatibility with fast telephotos, it outperforms virtually any compact. The W290’s 2 fps burst and slow AF rule it out for action photography.

Street Photography

Despite its larger size, the A7S II is surprisingly unobtrusive with a compact prime. Its silent electronic shutter mode is a boon. The W290 is very pocketable for spontaneous snaps but its image quality and focus limitations diminish its street creds.

Macro Photography

The A7S II supports specialized macro lenses and features IBIS that improves handheld close-ups. The W290 offers a fixed 10cm macro focus distance but lacks fine control or magnification.

Night and Astro Photography

The A7S II is a standout here, capable of clean high-ISO images thanks to its large sensor and Bionz X processor. Time-lapse and manual exposure modes empower creative night shots. The W290’s limited ISO and sensor size make night shots grainy and detail-poor.

Video Capabilities

The A7S II was a game-changer for video with 4K UHD recording at 30p, Full HD at up to 120 fps, clean HDMI output, and microphone/headphone ports for professional audio monitoring. I’ve used it extensively for interviews and documenting events.

The W290 offers only 720p HD video with no external mic support - adequate for family videos but unusable for professional work.

Travel Photography

While heavier, the A7S II’s versatility makes it ideal for travel photographers wanting quality and flexibility. The W290’s tiny footprint is attractive for travelers prioritizing convenience over image quality.

Professional Work

The A7S II supports RAW files, offers robust workflow integration, and delivers reliability and weather sealing - key pro requirements. The W290 is a consumer compact lacking these features.

Build Quality and Durability

The professional-grade A7S II offers a solid build with sealing against moisture and dust - important for outdoor use in adverse conditions. The W290’s plastic body and lack of environmental protections limit its durability.

Battery Life and Storage

The A7S II uses the NP-FW50 battery pack delivering around 370 shots per charge in my tests - moderate for mirrorless cameras. The W290’s battery life data is unofficial but typical compacts last fewer shots, relying on proprietary batteries that require an external charger.

Both cameras have a single storage slot. The A7S II accepts SD and Sony’s Memory Stick formats, favoring SDXC high-speed cards essential for 4K video. The W290 uses Memory Stick Duo and internal memory.

Connectivity: Wireless and Ports

• A7S II offers built-in Wi-Fi and NFC for easy sharing and remote control via smartphone apps, plus HDMI, microphone, headphone, and USB 2.0 ports.
• The W290 lacks wireless connectivity and external microphone/headphone jacks but has USB and HDMI output.

For professional workflows requiring tethering or remote operation, the A7S II clearly leads.

Price-to-Performance Considerations

The A7S II currently commands a price around $2,700* (new or used depending on market), reflecting its professional features and solid build. The W290, an affordable compact priced under $250 at release, targets completely different buyer expectations.

If your budget is tight and you want a simple, casual camera, the W290 remains a convenient point-and-shoot. But if image quality, video, or creative control matters, the A7S II offers value that justifies the investment.
