Sony HX7V vs Sony TX55: A Hands-On Comparison of Two 2011 Compact Camera Contenders

Choosing the right compact camera can be tricky, even with major brand names like Sony occupying the space. The Sony Cyber-shot series has always offered solid options, but models can vary drastically in handling, features, and versatility. Today, I’m diving into an in-depth comparison of two closely launched 2011 Sony compacts: the Sony HX7V and the Sony TX55. Though both cameras target the compact segment, their design philosophies and capabilities differ in ways that matter depending on what kind of photography you pursue.

Having personally tested both cameras extensively - shooting portraits, landscapes, macro, and even some casual sports and travel snaps - I’ll provide an expert, experience-driven take on which might best fit your needs. Along the way, I’ll analyze sensor performance, ergonomics, autofocus, video, and more. And for clarity, I’ll anchor points with direct comparisons, including physical size, sensor specs, control layouts, and photography genre strengths.

Let’s jump in and find out why each camera may or may not make sense for your specific use case.

Physical Size and Handling: Portability vs Grip Stability

Understanding how a camera feels in hand is crucial. I tested both models over several weeks in varying conditions - indoors, outdoors, and on the move.

• Sony HX7V: At 102 x 58 x 29 mm and 208 grams, this “small sensor compact” sports a traditional rectangular form with substantial grip. The body’s a bit chunky compared to ultra-compacts, giving better stability, especially when using the long 25-250mm zoom lens. The buttons have moderate spacing, allowing quick adjustment while shooting handheld. The fixed 3” XtraFine LCD works well in bright light, though it lacks touch capability.

• Sony TX55: Measuring 93 x 54 x 13 mm and weighing only 109 grams, this ultracompact camera is markedly thinner and smaller - closer to a slim phone. Its minimalist design has reduced physical controls but adds a 3.3” XtraFine OLED touchscreen with high resolution (1230k dots), offering superb image preview and menu navigation. However, the thin body makes gripping it for extended shooting sessions less comfortable, especially with heavier lenses.

Practical takeaway: If you prioritize pocket portability and screen quality, the TX55’s slim body and touchscreen deliver a more modern user experience. The HX7V, meanwhile, feels more robust and stable in hand, better suited for longer, intentional shooting sessions.

Control Layout and Interface: Traditional Buttons vs Touchscreen Navigation

Controls are where real-world usability often triumphs over raw specs. I extensively compared both cameras’ top and back panel layouts.

• Sony HX7V: The camera features classic and tactile buttons with a dedicated zoom lever, shutter release, and mode dial. The lack of touchscreen means you rely on physical input for settings - which, in my experience, is faster for quick scene changes without looking away from the action. The menu system is straightforward but did feel dated compared to later generations.

• Sony TX55: This model relies heavily on its touchscreen-driven interface - the OLED display responds crisply to taps and swipes for settings, focus point selection, and review. Physical buttons are minimal, which suits casual users who prefer a smartphone-like experience. However, for fast adjustments during dynamic shooting, the touchscreen interface can sometimes be less intuitive, especially when wearing gloves or in bright sunlight.

Summary: The HX7V’s button-centered control benefits photographers looking for precise, tactile input, while the TX55’s touchscreen pushes a more streamlined, consumer-friendly experience. Your choice here depends on whether you prefer traditional or modern controls.

Sensor and Image Quality: The 1/2.3" BSI-CMOS Sensors Compared

Sensor technology greatly affects image quality, especially in compact cameras where physical dimensions limit pixel size and light gathering.

Both cameras use a 1/2.3" BSI-CMOS sensor measuring 6.17 x 4.55 mm with a resolution of 16 MP (4608 x 3456 pixels), along with an anti-aliasing filter and similar ISO ranges (Sony HX7V: ISO 125–3200, TX55: ISO 100–3200).

• Sony HX7V: Despite sharing sensor size/resolution with the TX55, the HX7V’s image processing pipeline optimized for its longer focal range produces respectable detail with moderate noise levels up to ISO 800. The BIONZ processor handles color reproduction well, with natural skin tones in portraits and punchy yet accurate colors in landscapes. The optical image stabilization helps reduce blur in lower light and telephoto shots.

• Sony TX55: The OLED screen hints at the camera's focus on excellent image preview quality. In actual shooting, the TX55 yields sharp images thanks to a slightly faster maximum aperture (F3.5-4.8 vs HX7V’s F3.5-5.5) in its tele-end. Macro work especially benefits from its close focusing capability (3cm minimum focus distance). Noise control performs comparably to the HX7V up to ISO 800, though noise becomes more noticeable from ISO 1600 onwards.

Image quality verdict: Neither camera competes with larger-sensor models, but both offer image quality solid enough for casual enthusiasts. The HX7V’s longer zoom range is handy for telephoto shots at the cost of slightly smaller max aperture, while the TX55’s lens is brighter and better suited for close-up and general purpose.

LCD Performance and User Experience

An often overlooked but important aspect is the rear LCD - the window through which you compose and review photos.

• Sony HX7V: Displays a 3” fixed XtraFine LCD with 921k-dot resolution. It delivers bright, crisp viewing even in daylight but lacks touchscreen input. The fixed angle can present challenges shooting from unorthodox positions or low angles.

• Sony TX55: Features a larger 3.3" OLED screen with 1230k-dot resolution and touchscreen technology. The OLED technology provides richer colors, higher contrast, and deeper blacks compared to the LCD on the HX7V, making it exceptional for image review and composition. Touch navigation simplifies changing focus points and accessing menus but has trade-offs in durability and responsiveness under extreme conditions.

Bottom line: The TX55’s OLED touchscreen is a leap forward in user experience and image feedback for casual shooting. The HX7V’s LCD remains perfectly adequate but more traditional and static.

Autofocus Performance: Contrast-Detection in Both, But Which One Feels Snappier?

Both models employ 9-point contrast-detection autofocus systems without phase detection or advanced tracking capabilities. I tested them under normal and low-light conditions to gauge speed, accuracy, and consistency.

• Sony HX7V: Autofocus is competent, especially in well-lit conditions, locking quickly on central subjects. Given the camera’s longer zoom range, AF hunting can occur in low light or at full telephoto zoom, though the optical stabilization helps maintain focus stability during composition.

• Sony TX55: Focus is slightly faster at wide to mid-focal lengths, likely due to shorter zoom range and faster max aperture. The touchscreen interface lets you select AF points with your finger, which enhances accuracy for static subjects. However, AF speed drops slightly in low light.

Neither camera offers continuous AF tracking or face detection, which limits their suitability for fast-moving subjects like sports or wildlife.
