Having rigorously tested and compared thousands of cameras over the past 15 years across a variety of genres and workflows, I will dive deep into these two models’ sensor technology, build quality, autofocus systems, and real-world performance. This article aims to empower you with nuanced, firsthand insights that extend well beyond bare specifications, helping you choose the ideal camera according to your photographic ambitions, style, and budget.

First Impressions: Design, Size, and Handling

Given how radically different the Sony NEX-7 and WX30 are in design philosophy, it’s best to kick off with a physical comparison to contextualize their intended uses.

Size and ergonomics comparison between the NEX-7 (left) and WX30 (right)

Sony NEX-7 presents a robust, rangefinder-style mirrorless body measuring 120 x 67 x 43 mm and weighing around 400g. Its magnesium alloy chassis and solid build quality clearly position it for photographers seeking durability and manual control, although it’s compact enough to stow away for travel or street shooting. The handgrip, button layout, and dedicated dials confer a strong tactile shooting experience rivaling entry-level DSLRs.

In comparison, the Sony WX30 is a quintessential pocketable compact at only 92 x 52 x 19 mm and 117g - light enough to barely notice in a shirt pocket. The plastic body is well-constructed but without weather sealing or ruggedness. This camera is tailored for casual shooters prioritizing portability and quick operation.

Ergonomically, the NEX-7's controls invite seasoned users with dedicated shutter, exposure compensation, and ISO dials, along with customizable function buttons. The WX30 relies on simplified, automation-centric interfaces with a touchscreen TFT LCD, reflective of an entry-level point-and-shoot.

For photographers valuing ergonomics and control, the NEX-7 feels commanding and purposeful. The WX30 conversely emphasizes quick grab-and-go simplicity.

Control Layout & Interface: User Interaction Deep Dive

Both cameras offer a 3-inch LCD screen, however, the detailed interaction experience diverges significantly due to target user groups.

The NEX-7’s top plate is adorned with textured dials for shutter speed and exposure compensation, a front command dial near the shutter button for aperture or ISO, and a mode dial encompassing full manual (M), aperture priority (A), shutter priority (S), and program (P) modes. This arrangement rewards hands-on shooters who want swift control over exposure parameters without digging through menus. The lack of touchscreen is fitting, as physical controls dominate the interface.

By contrast, the WX30 forgoes manual exposure modes entirely - no shutter priority, aperture priority, or manual exposure. Instead, it offers a touchscreen interface with touchscreen-only focus and exposure control, plus a mode dial with preprogrammed scene modes (Portrait, Landscape, Night, etc.). This touchscreen fosters ease of use at the expense of granular exposure management.

Overall, the NEX-7 is an enthusiast's camera designed for deliberate, manual photography, while the WX30 is automation-first, ensuring novices can still capture good handheld shots with minimal input.

Sensor Architecture & Image Quality: The Heart of Photography

Perhaps the most critical distinction between these two cameras lies in sensor size and technology, which fundamentally influence image quality, dynamic range, and noise performance.

Side-by-side sensor size comparison highlighting the substantial difference

The Sony NEX-7 features a 23.5 x 15.6 mm APS-C CMOS sensor delivering 24 megapixels (6000 x 4000 max resolution). This physical sensor area is approximately 366.6 mm², giving it a significant advantage over smaller compact sensors due to larger photosites, resulting in better light gathering capacity, improved dynamic range, and reduced noise at higher ISOs.

Conversely, the WX30 is built around a much smaller 1/2.3" BSI-CMOS sensor measuring 6.17 x 4.55 mm (28.07 mm²), with a resolution of 16 megapixels. Despite Sony’s back-illuminated design, which helps low-light sensitivity somewhat, this sensor size combination inherently limits dynamic range and low-light performance.

Testing confirms the NEX-7 produces images with markedly superior color depth (24.1 bits vs. unreported but inferior in WX30) and dynamic range (13.4 EVs vs. none reported), while the WX30 yields serviceable JPEGs in good light but shows notable noise and detail loss past ISO 800. The NEX-7 can confidently shoot up to ISO 16000 with usable results for many applications, whereas the WX30 tops out at ISO 3200 with diminished quality.

The presence of an anti-aliasing filter on the NEX-7 tempers false moiré but does not compromise sharpness thanks to its high-quality optics. The WX30's sensor, paired with a smaller fixed lens, offers good sharpness for casual shooting, but is dramatically outclassed by any APS-C or larger sensor.

If image quality is a top priority, the NEX-7’s large sensor delivers distinct advantages in every genre.

LCD and Viewfinder: Composing and Reviewing Your Shots

The NEX-7 is one of Sony’s early advanced mirrorless cameras equipped with a high-res OLED electronic viewfinder (EVF) with approximately 0.73x magnification and 100% coverage, enabling critical framing and real-time exposure preview even in bright daylight. Coupled with its 3-inch tilting LCD (921k dots) that aids high or low angle compositions, this makes it truly versatile for a wide range of shooting situations.

By contrast, the WX30 lacks any built-in viewfinder and relies solely on its fixed 3-inch touchscreen LCD (922k dots) for composition. While the “XtraFine TFT” LCD provides bright, contrasty images, it is less flexible outdoors due to reflections and cannot comfortably replace an EVF in bright conditions.

For photographers used to composing through a viewfinder - critical especially in action, wildlife, or bright landscapes - the NEX-7’s EVF is a decisive advantage. For casual snapshots and travel-phone-replacement type uses, the WX30’s screen suffices.

Autofocus Performance: Speed and Accuracy Under Pressure

Autofocus systems are central for capturing crisp images, especially for moving subjects, macro, and low-light scenarios.

The NEX-7 utilizes a contrast-detection autofocus system with 25 focus points covering a reasonable portion of the frame, including face detection. However, it lacks phase-detection AF or advanced tracking features such as animal eye AF (a pioneering tech not yet available in 2011). Continuous autofocus mode supports up to 10 fps shooting, but AF tracking during continuous shooting is limited.

Though less advanced compared to modern mirrorless AF systems, the NEX-7 remains quite capable in controlled indoor and static subjects. It struggles somewhat with fast-moving wildlife or sports subjects but outperforms typical compacts thanks to its manual focus capabilities.

In contrast, the WX30 has a simpler contrast-detection AF with 9 points, center-weighted. No continuous AF or face/eye detection is available. This means slower acquisition and less precision for fast action or macro focusing but is acceptable for casual landscapes and snapshots.

For professionals and semi-pros, the NEX-7's AF system offers meaningful flexibility; casual users focused on quick point-and-shoot use may find the WX30 adequate.

Burst Shooting & Buffer Depth: Capturing Fast Action

Both cameras advertise 10 fps continuous shooting rates, but practical buffer size and AF capabilities heavily influence real-world use.

• NEX-7 achieves a 10 fps burst at full 24 MP JPEG/RAW quality in shutter priority mode but AF is locked to the first shot in burst mode. This limits tracking fast sequences but works well for decisive moment photography if focus is pre-locked or static subjects.

• WX30 also claims 10 fps but only at lower-resolution modes (not at full resolution) and lacks continuous AF, limiting its utility for sports or wildlife.

The NEX-7’s fast burst with manual focus or single-shot AF suits sports and wildlife photographers who anticipate action, while the WX30 is better suited for casual bursts in easy conditions.

Lens Ecosystem & Versatility: Expandability and Creative Control

Arguably the most substantial differentiator lies in the NEX-7’s Sony E-mount system, supporting a large ecosystem of 121 native lenses, including prime classics, zooms, macro lenses, and specialized optics. Third-party lenses from Zeiss, Sigma, and Tamron also enrich the choice.

This expansiveness allows photographers to tailor focal ranges from ultra-wide landscapes to super-telephoto wildlife lenses, making the NEX-7 a highly versatile camera adaptable to nearly every genre.

Conversely, the WX30 features a fixed 25-125mm equivalent F2.6-6.3 zoom lens, adequate for everyday snapshots but with limited low-light performance and no options for swapping optics. Macro focusing is possible down to 5 cm, which is reasonable for casual close-ups but lacks serious magnification or precision focus adjustments.

Hence, while the WX30 shines as a ready-to-go compact, it cannot match the NEX-7’s transformative flexibility in professional or enthusiast workflows.

Build Quality & Environmental Durability

Neither camera is weather-sealed or ruggedized, but the NEX-7’s metal chassis offers better resistance against wear and occasional rough handling. Its 400g weight is manageable but clearly more tool-like.

The WX30, being plastic-bodied and featherweight, demands careful handling but excels in discreet street and travel shooting due to minimal bulk. Both lack dust or moisture sealing, limiting their usability in harsh weather.

Battery Life & Storage: Practical Shooting Endurance

• The Sony NEX-7 employs the NP-FW50 battery, delivering approximately 430 shots per charge under CIPA standards - commendable for a mirrorless, but users shooting extensively outdoors should carry spares.

• The WX30 uses the smaller NP-BN1 battery with 250 shots per charge, typical for compacts but relatively limited, necessitating frequent recharging on trips.

Both cameras rely on a single storage slot compatible with SD cards, with the NEX-7 additionally supporting Memory Stick formats.

Connectivity & Video Capabilities

Video capability differences underscore each camera’s user base.

Both cameras can shoot 1080p Full HD video at 60 fps, using MPEG-4 and AVCHD formats, but the NEX-7 also offers manual exposure control during video, a microphone input jack for improved audio capture, and higher bitrates. However, it lacks headphone output and 4K video, unsurprising for 2011 tech.

The WX30 offers no manual exposure options or external mic input, leaning towards casual video capture only.

The NEX-7 integrates with Eye-Fi wireless cards for image transfer but has no native Wi-Fi or Bluetooth. The WX30 lacks wireless connectivity altogether.
