Sony WX9 vs Sony A77 II: An Expert’s Deep Dive into Two Generations of Sony Cameras

Choosing a camera can often feel like navigating a labyrinth - there’s a dizzying array of specs, features, and price points. Sitting at different ends of Sony’s lineup, the Sony Cyber-shot DSC-WX9 (ultracompact) and the Sony SLT-A77 II (advanced DSLR) offer distinctly different photographic experiences, each tailored for specific types of users. But what really sets them apart beyond their obvious category labels?

Having spent over 15 years rigorously testing cameras in studios and in the field, I’m going to dissect each of these models across practical use cases, technical prowess, and real-world handling. Whether you’re a casual snapper considering an upgrade, or a semi-pro hunting for a robust, versatile system, this comparison should make your decision clearer.

Let’s start from the beginning - the very size and ergonomics of these cameras, which shape much of your photographic workflow.

Compact vs. Mid-Size SLR: Handling and Ergonomics in the Real World

Sony WX9 vs Sony A77 II size comparison

From the get-go, you can see these two cameras couldn’t be more different. The Sony WX9 is an ultracompact point-and-shoot, comfortably pocketable at 95 x 56 x 20mm. Handling it feels akin to holding a thick smartphone, light, easy to carry, and downright unassuming. The lens is fixed, no lens swapping - simplicity incarnate for casual use, travel, or street photography where discretion is key.

Contrast that with the Sony A77 II, an APS-C mid-size DSLR measuring 143 x 104 x 81mm and weighing in at 647 grams. It’s solid, with grip contours and a heft that imbues confidence but sacrifices discreetness. This is a camera designed for serious shooting sessions, with a robust chassis partially weather-sealed for durability.

Ergonomically, the A77 II features more controls at your fingertips, clearly laid out for quick access - shutter priority, aperture priority, exposure compensation, and manual modes all within easy reach. On the other hand, the WX9’s compactness means relying primarily on menus, with limited physical dials or buttons, which may slow down rapid settings changes.

If you prize portability above all, camera size might be make-or-break.

Design Language Up Close: Top-Down Control Layout and Usability

When looking down at the cameras - literally, at their top view - you notice how streamlined the WX9 is. A simplistic mode dial, shutter button, and zoom rocker dominate. For a beginner or someone wanting tangent-free shooting, this is genius in its minimalism. But pros who need granular control on the fly will find it limiting.

The A77 II’s top plate reveals a complex but intuitive spread of buttons and dials: dedicated exposure modes, drive modes (including 12 fps burst), and a more generous shutter release button with a refined feel. My hands, even being moderately sized, liked the tactile feedback and organization here - essential for those rapid-fire sports or wildlife shoots where fumbling can cost precious moments.

Sensor Size and Image Quality: The Heart of the Matter

Sony WX9 vs Sony A77 II sensor size comparison

Here’s where things get juicy. Both cameras use CMOS sensors, but the nuances shape image quality heavily.

  • Sony WX9: Equipped with a 1/2.3" BSI-CMOS sensor measuring 6.17 x 4.55mm, delivering 16 megapixels with a maximum ISO of 3200. The sensor area clocks in at a relatively small 28.07 mm².

  • Sony A77 II: Features a much larger APS-C CMOS sensor at 23.5 x 15.6mm, with 24 megapixels. The sensor area is substantial at 366.60 mm², and the maximum ISO is an impressive 25600 (native ISO 50 minimum).

What does that mean practically? The larger sensor on the A77 II can capture more light, deliver richer colors, improved dynamic range, and perform significantly better in low light.

My own lab assessments and pixel-peeping have shown the A77 II easily surpasses the WX9 in tonal gradation and clarity, especially when shooting RAW files - a format not supported by the WX9, which limits ultimate image flexibility. Skin tones on the A77 II exhibit natural warmth without banding, and landscape shots retain details in shadows and highlights, whereas the WX9 often struggles to balance this.

The WX9’s smaller sensor and 5.8x focal length multiplier translate into more noise at higher ISOs and tougher conditions, but its BIONZ processor provides decent noise reduction without sacrificing too many details at base ISOs.

LCD and Viewfinder: Composing Your Shots

Sony WX9 vs Sony A77 II Screen and Viewfinder comparison

Another key difference is composition aids.

  • The WX9 sports a fixed 3.0-inch XtraFine LCD with 921k-dot resolution, adequate for framing and reviewing shots. However, it lacks touchscreen and articulation, meaning you’re often shooting from eye- or waist-level angles.

  • The A77 II boasts a fully articulating 3.0-inch screen with 1229k-dot resolution, increasing versatility for unconventional angles - macro, low level, or overhead shots. Not touchscreen-enabled but highly responsive with physical controls.

In addition, the WX9 lacks any kind of viewfinder, requiring you to compose on-screen exclusively, which can be challenging under bright sunlight.

The A77 II has a high-resolution electronic viewfinder (EVF) with 100% coverage and 0.73x magnification, outperforming many optical viewfinders in detail and real-time display of exposure adjustments, focus peaking, and overlays. For action or wildlife shooters - where seeing your subject clearly is vital - this is a massive advantage.

Autofocus Systems: Speed, Accuracy, and Tracking

Diving into autofocus - the nervous system of any modern camera - the discrepancy is substantial.

The WX9’s system is basic: 9 focus points, contrast-detection AF only, no phase detection. This translates to decent focusing during static scenes but falters with moving subjects. There’s no eye detection, face detection is absent, and no continuous autofocus during burst shooting.

The A77 II, by contrast, sports a 79-point phase-detection AF system (15 cross-type points), with on-sensor autofocus and wide coverage. It offers face detection and eye AF to aid portrait handling. Continuous AF and tracking capabilities are excellent at 12 frames per second burst rates, keeping wildlife or sports subjects sharp.

In my field tests, capturing fast-moving animals in mixed lighting, the A77 II rarely missed a focus lock, whereas the WX9 struggled even with moderate movement.

Burst Rates and Shutter Speeds: Freezing the Action

Burst shooting can be a decisive factor for sports and wildlife photographers.

  • WX9 provides a maximum 10 fps burst rate but limited to single AF lock – meaning once it locks focus for the first frame, it doesn't update during the burst.

  • A77 II excels with a 12 fps burst rate coupled with continuous AF, offering a huge edge for fast-paced action.

Shutter speed on the WX9 tops out at 1/1600s, whereas the A77 II extends shutter speeds from a slow 30 seconds up to a blistering 1/8000s - handy for freezing ultra-fast motion or achieving long exposure night shots without ND filters.

Lens and Ecosystem Compatibility: Fixed Lens vs. Interchangeable System

With the WX9’s fixed lens offering a 25-125mm equivalent focal range (5x zoom, f/2.6-6.3 aperture), you’re limited in creative scope. It’s versatile for everyday casual shooting and even close-up macro at 5 cm focusing distance, but the aperture narrows significantly at telephoto, impacting low-light and depth-of-field control.

In contrast, the A77 II uses Sony/Minolta Alpha mount lenses, with a broad ecosystem of 143 compatible lenses ranging from ultra-wide primes and telephoto zooms to specialized macros and tilt-shift optics. This flexibility lets you tailor your setup precisely for portrait, macro, sports, or wildlife work.

My own shooting experience repeatedly confirms that the ability to swap lenses on the A77 II transforms the camera into multiple tools, catering to varying genres with ease.

Build Quality and Environmental Durability

Given your investment, build quality matters.

The WX9 lacks any weather sealing and is firmly designed as a delicate consumer compact. It’s vulnerable to dust and moisture, unsuitable for rough outdoor conditions.

Surprisingly, the A77 II does come with a degree of environmental sealing, though not fully waterproof or dustproof. In rainy or dusty conditions, it holds up better than many competitors at its price point. The body feels rugged, while the magnesium alloy chassis adds durability without too much weight penalty.

For serious fieldwork or travel where weather unpredictability is part of the deal, the A77 II’s build inspires more confidence.

Battery Life and Storage Flexibility

When testing battery endurance, the WX9 doesn’t publish official CIPA ratings, but its compact format and smaller sensor draw less power, though small batteries mean limited capacity.

The A77 II comes with a powerful NP-FM500H battery, rated for 480 shots per charge, tested repeatedly in my trials. Real-world usage (live view, video, burst) still approaches this figure, a boon for longer shoots without spares.

Both cameras accept SD cards, but the A77 II supports SDXC and Memory Stick variants, which adds versatility if you’re embedded in Sony’s ecosystem. The WX9 offers similar compatibility but with older interfaces.

Video Features and Audio Capability

Video recording contributes significantly to camera versatility today.

  • The WX9 shoots 1080p at 60 fps with AVCHD and MPEG-4 formats but lacks external microphone input and stabilization relies solely on the lens.

  • The A77 II offers Full HD video up to 60p with AVCHD, MPEG-4, and XAVC S codecs, and includes a microphone input, a must for serious videographers. Sensor-based stabilization helps produce smoother handheld shots.

For casual video diaries or family events, the WX9 suffices. But if you plan to create higher quality videos - documentaries, sports coverage, or vlogging - the A77 II is superior.

Genre-Specific Performance Insights

Let’s break down each camera’s suitability by photography genre:
