Sony TX7 vs Sony W320: An In-depth Ultracompact Camera Comparison for Photography Enthusiasts

Sony’s line of ultracompact cameras, especially from the early 2010s, marked an intriguing period where convenience and imaging tech converged. Two cameras that perfectly exemplify this era are the Sony Cyber-shot DSC-TX7 and the Sony Cyber-shot DSC-W320. Released concurrently in January 2010, these models target users seeking pocketable point-and-shoot options - but which one truly deserves your attention?

Having personally tested thousands of cameras over the past 15 years, I aim to demystify the practical performance, technical merits, and overall value of these two compact shooters. Whether you’re a casual snapshooter or a photography enthusiast scouting for a lightweight travel companion, this comprehensive guide will provide you with insights rooted in experience and technical analysis.

Size and Ergonomics: Pocketability Meets Usability

First impressions matter, especially when size and feel govern how often you’ll actually carry a camera. Both the TX7 and W320 are genuinely pocket-friendly ultracompacts, yet there’s more than meets the eye when comparing their ergonomics.

The Sony TX7 measures 98 x 60 x 18 mm and weighs 149 grams, while the Sony W320 is slightly smaller at 93 x 52 x 17 mm, weighing 117 grams. That difference may seem negligible, but in hand, the TX7’s subtle thickness and carefully sculpted edges provide a more secure grip, reducing the risk of slips.

The TX7 also proudly sports a 3.5-inch touchscreen with 921k dots - a real treat for an ultracompact from 2010 - bringing ease of navigation and quick setting changes. On the other hand, the W320 features a smaller 2.7-inch LCD with only 230k dots, lacking touch functionality. This difference heavily influences how intuitive and enjoyable the shooting experience feels, especially when you’re fiddling with exposure compensation or shooting modes on the fly.

If you prize portability above all and have smaller hands, the W320’s lighter, more diminutive frame will appeal. For those valuing better handling and a crisp, large display, the TX7 takes the cake.

Design and Control Layout: Ease of Use Through Intuitive Design

Both cameras feature simple control schemes befitting their category but differ noticeably in button arrangement and ease of access.

On the TX7, Sony integrated a minimalist top plate with well-placed shutter and zoom controls, enabling quick operation with one hand. The touch interface significantly reduces dependence on physical buttons, speeding up workflows in varied lighting situations. However, the absence of manual focus and exposure modes limits creative control, an understandable compromise for ultracompacts.

The W320, by contrast, emphasizes physical buttons given its lack of a touchscreen. The controls are slightly more cramped but straightforward, though setting changes feel less fluid compared to touch-based navigation on the TX7.

Neither camera supports full manual exposure or focus bracketing - standards not typically expected here - but both offer center-weighted and spot metering, which help with challenging exposures. The W320 lacks custom white balance, available on the TX7, which may matter to users experimenting with lighting conditions.

For photographers who value responsiveness coupled with user-friendly design, especially novices or travelers aiming to shoot quickly, the TX7’s touchscreen interface is a modern luxury well worth the slightly larger body.

Sensor and Image Quality: Size, Resolution, and Technology at a Glance

Image quality invariably hangs on sensor size, resolution, and processing power. Let’s unpack those specs carefully.

Both boast a backside-illuminated (BSI) CMOS sensor, but wait - here’s an important correction: the W320 uses a CCD sensor while the TX7 benefits from a 1/2.4" BSI-CMOS sensor. This distinction shapes performance significantly.

• Sony TX7: 10 megapixels, 1/2.4” BSI-CMOS sensor (6.104 x 4.578 mm, 27.94 mm²)
• Sony W320: 14 megapixels, 1/2.3” CCD sensor (6.17 x 4.55 mm, 28.07 mm²)

At first glance, the W320’s higher megapixel count suggests sharper images. However, sensor technology matters. The TX7’s BSI-CMOS sensor historically delivers better low-light performance and dynamic range compared to CCDs of similar size - thanks to more efficient photon capture and faster readout.

In practice, I found the TX7 produces images with cleaner shadows, less noise at ISO 800+, and more natural colors under mixed lighting. The W320’s images sometimes display more noise and less vibrant hues, though its 14MP resolution can show finer detail in bright, controlled settings.

However, neither camera shoots RAW, limiting post-processing flexibility. JPEG output is decent but not remarkable by modern standards.

If image quality in varied environments (indoor, shadows, dusk) is a priority, the TX7’s sensor technology and processor combo (Bionz engine) offer an advantage, despite the lower megapixel count.

LCD and Viewfinder: Display Matters for Composition and Review

Neither camera features an electronic viewfinder, which is typical for this category, but the rear screen quality and size considerably affect framing and image review.

The TX7’s 3.5-inch, 921k-dot touchscreen delivers ample resolution and size for detailed previews. Its capacitive touch removes menu navigation headaches and facilitates quick focus point selection in live view. This ease is crucial when shooting spontaneity-heavy genres such as street photography.

The W320 offers a 2.7-inch screen with only 230k dots, lacking touch capability. While sufficient for composing bright outdoor shots, low resolution hampers precise review, especially in bright daylight or when critical focusing is desired.

For casual users, the TX7’s screen improves confidence in composition and playback, essentially reducing the need for repeat shots. If you often shoot outdoors or require quick on-screen navigation, the TX7 wins hands down.

Performance and Autofocus: Speed, Accuracy, and Usability in Real Life

Focus speed and accuracy in ultracompacts can be a mixed bag. Let’s talk about what I experienced testing both.

Both cameras use contrast-detection autofocus with nine focus points, center-weighted metering being standard. Neither offers continuous autofocus or face/eye tracking, understandably given the age and design goal.

• The TX7 autofocus system is noticeably snappier, aided by the BSI sensor’s faster readout and the Bionz processor’s calculations. It manages to lock focus effectively even in moderate low light. The touchscreen also allows you to tap-to-focus seamlessly, a bonus for precise composition.
• The W320 autofocus is reliable in bright scenarios but can lag or hunt longer in dimmer conditions, partly due to the CCD sensor’s slower data readout and absence of touch focus.

Continuous shooting-wise, the TX7 can shoot up to 10 frames per second, albeit at a constrained buffer and JPEG-only. The W320 maxes out at a sluggish 1 fps, restricting action photography.

If you shoot wildlife, sports, or street scenes where quick focus and burst capture matter, the TX7 better suits your needs.

Lens and Zoom: Range, Aperture, and Versatility

Both cameras feature fixed lenses with similar zoom ranges:

• TX7: 25-100 mm equivalent, f/3.5-4.6 aperture
• W320: 26-105 mm equivalent, f/2.7-5.7 aperture

The W320’s lens opens wider at the wide end (f/2.7), helpful for indoor and low-light shooting to a point. The TX7’s lens is faster in telephoto reach and benefits from optical image stabilization, mitigating camera shake, especially relevant given its longer maximum focal length.

The TX7 includes optical image stabilization (Optical SteadyShot), greatly improving handheld sharpness at moderate zooms and slower shutter speeds. By contrast, the W320 lacks any image stabilization, making handheld shots above ~1/60s shutter more prone to blurring, limiting practical telephoto use under mid to low light.

The TX7’s macro focusing down to 1 cm offers excellent close-up capabilities, superior to the W320’s 4 cm minimum focus distance.

Flash and Low Light Performance: Illuminating and Noise Control

Both cameras include built-in flashes with similar modes - Auto, On, Off, and Slow Syncro - but with different ranges:

• TX7 flash range: ~3.8 meters
• W320 flash range: ~4.8 meters

A higher range doesn’t necessarily translate to better flash photos, considering synchronization accuracy and sensor sensitivity.

The TX7's BSI sensor handles higher ISO settings more gracefully, producing less noise around ISO 800-1600. The W320's CCD sensor shows significant noise above ISO 400, which can be limiting indoors or at night.

I found the TX7 more reliable for low-light situations, combining optical image stabilization with the ability to push ISO settings, delivering cleaner, sharper images. The W320 demands careful flash use or additional lighting to maintain clarity.

Video Capabilities: Quality, Formats, and Usability

Video shooters will find marked differences here.

• The TX7 supports Full HD 1080p video at 60 fps in AVCHD format, an excellent feature in 2010 for smooth, high-quality footage.
• The W320 is limited to VGA resolution (640 x 480) at 30 fps using Motion JPEG, producing comparatively grainy and low-res clips.

Neither camera includes microphone or headphone jacks, so audio quality defaults to built-in mics, acceptable for casual use but not professional.

The TX7’s touchscreen aids quick recording operations, whereas the W320 involves more manual button presses.

If decent video quality is important to you, the TX7 is clearly the stronger candidate, extending its usefulness beyond stills.

Battery Life and Storage: Staying Powered and Saving Shots

Battery performance on ultracompacts tends to be modest. Both cameras use a Sony NP-BN1 battery model, which historically delivers around 200 to 250 shots per charge in still mode under mixed conditions based on my experience.

Neither model shines particularly here, so bringing spares or charging often is advisable for extended outings.

Regarding storage, both cameras accept:

• TX7: Memory Stick Duo / Pro Duo / Pro HG-Duo and optional SD cards
• W320: SD / SDHC and Memory Stick Duo / Pro Duo / Pro HG-Duo

This compatibility means plenty of options for expanding storage, although I prefer SD cards for their availability and speed.

Build Quality and Weather Resistance: Durability for the Long Haul

Both cameras have the typical plastic and metal body mix common in ultracompacts. Neither offers weather sealing, dustproofing, shockproofing, or freezeproofing.

For casual use and travel in temperate climates, this is generally acceptable - but I'd caution against heavy outdoor or adventure use without protective accessories.
