Comparing Sony HX90V vs Sony TX7: Which Compact Powers Your Passion?

Choosing a compact camera can feel like navigating a fascinating yet bewildering gadget jungle. Sony’s Cyber-shot line has long promised pocket-friendly prowess, but with models like the HX90V and TX7 spanning different eras and styles, which one deserves your hard-earned cash and photographic devotion? Having spent countless hours behind the viewfinder - and in my experience testing hundreds of cameras across genres - I’m here to walk you through a detailed, no-nonsense comparison of these two Sony compacts.

We'll dissect everything from sensor tech to ergonomics, and from real-world autofocus performance to suitability across photography types. Spoiler: both cater to distinct needs and come with trade-offs you should know intimately before buying.

Body and Design: Size, Handling, and Portability

First impressions matter, and it's no secret that handling can make or break your shooting experience. The Sony HX90V is a superzoom compact, measuring 102 x 58 x 36 mm and tipping the scales at 245 grams. The TX7 is a more petite ultracompact contender at 98 x 60 x 18 mm and just 149 grams. In-hand, this translates to a firmer grip and more substantial presence with the HX90V versus a slimmer, lighter companion for the TX7 - ideal if pocketability tops your priority list.

The HX90V boasts a traditional control layout with plenty of physical buttons and a top control dial, which seasoned shooters will appreciate for quick adjustments on the fly. The TX7 trims the controls aggressively to maintain its slender profile, trading tactile richness for minimalism.

Looking at the top, the HX90V (left) features a pop-up electronic viewfinder - a rarity in compacts that plays a big role in bright outdoor shooting - while the TX7 relies solely on its bright 3.5-inch fixed touchscreen.

Both cameras come with a tilting (HX90V) or fixed (TX7) LCD; more on that shortly. Neither provide weatherproofing, which is typical for these classes but worth noting if you plan to shoot in challenging environments.

In practice: I'd grab the HX90V for longer outings where better handling and zoom reach matter. The TX7 fits neatly into a shirt pocket and never feels like extra baggage, a genuine boon for travelers seeking discretion.

Sensor and Image Quality: How Much Punch From Their Small Sensors?

Sony employs 1/2.3-inch BSI-CMOS sensors in both models, with subtle differences. The HX90V’s sensor is 18 megapixels, while the TX7 has 10 megapixels. Picture sizes max out at 4896x3672 pixels for the HX90V and 3456x2592 pixels for the TX7.

While both sensors share similar physical dimensions (around 6.1 x 4.5 mm), the HX90V’s higher resolution provides more detail potential but at the risk of increased noise if pushed in low light. The TX7’s lower pixel count generally means larger pixels, which can yield better signal-to-noise ratios and cleaner images, albeit with less cropping flexibility.

Sony historically uses an antialias filter on these sensors, which slightly reduces sharpness to prevent moiré artifacts - smart for general photography but limits resolution at pixel-peeping levels.

From my lab tests and field shooting, the HX90V delivers sharper images under good lighting conditions due to its higher pixel count and the BIONZ X processor’s more advanced noise reduction pipeline. It also shines brighter at ISO 80–400, giving crisp, clean results. The TX7 performs surprisingly well for a 2010-era sensor, with decent color reproduction and manageable noise up to ISO 800, but its native sensitivity starts at ISO 125 and maxes out at 3200, so low-light is limited.

For dynamic range - the ability to render details in both shadows and highlights - the HX90V slightly outperforms the TX7, producing more balanced exposures in tricky lighting, thanks again to the slightly newer sensor and processing tech.

Real-world verdict: For landscape or studio photography that demands resolution and detail, the HX90V is the better bet. For casual snapshots or travel where file size and ease trump pixel count, the TX7’s sensor holds up well.

Focus and Autofocus: Speed, Modes, and Tracking

Both cameras use contrast-detection autofocus, which - though slower and less consistent than phase-detection found in more modern systems - gets the job done in bright conditions.

The HX90V offers more generous focus modes, including face detection and tracking capabilities, along with selectable AF areas (center, multi-area, selective, tracking). In addition, continuous AF at 10 fps burst shooting helps steady moving subjects.

In contrast, the TX7’s AF system is far simpler, with just 9 focus points and no face-or-eye detection. Its autofocus is mainly single-shot, which means you need to anticipate action better or rely on subject static-ness.

A fascinating omission: the HX90V lacks phase-detection but compensates with refined contrast AF algorithms and integrated image stabilization to reduce blur. The TX7’s system is decidedly less sophisticated but surprising nimble considering its age.

In wildlife or action photography tests, the HX90V consistently nails focus faster and sustains accurate tracking in decent light, while the TX7 struggles with fast-moving subjects, often hunting or missing focus entirely.

Bottom line: For portraits where face and eye detection dramatically improve keeper rates, and sports or wildlife where tracking is critical, HX90V is clearly superior. The TX7 is better for static scenes such as landscapes or macro where focus precision rather than speed is paramount.

Using Their Screens and Viewfinders: Framing and Interaction

The HX90V features a tilting 3-inch LCD screen with 921k-dot resolution, which tilts up ~180 degrees, making selfies or low-angle shots easier. It complements this with a pop-up electronic viewfinder (EVF) sporting 638k-dot resolution and 100% coverage, enabling precise composition under bright sunlight - a major plus.

Conversely, the TX7 comes with a larger 3.5-inch fixed touchscreen but no viewfinder. The touchscreen supports autofocus point selection and menu navigation, enhancing usability but potentially awkward for some in-sun situations.

From practical experience, the HX90V’s EVF is a decisive advantage if you shoot outdoors or in harsh lighting - it reduces eye strain and delivers more accurate framing. Meanwhile, the TX7’s touchscreen is more modern but less versatile due to its fixed angle and lack of a viewfinder.

My take: If you prefer composing through a viewfinder or want flexibility in shooting angles, the HX90V wins handily. For casual photographers who enjoy touch operation and simpler framing, the TX7 is adequate.

Zoom Range and Lens Performance: Superzoom vs Snapshots

Sony’s HX90V packs a powerful 30x optical zoom (24–720 mm equivalent), which is remarkable in such a compact body. The max aperture of f/3.5–6.4 reflects some light-gathering compromises at telephoto lengths but remains usable for daylight shooting. It also offers a 5 cm macro focus range.

The TX7 plays the more modest role with a 4x zoom (25–100 mm equivalent) at f/3.5–4.6, featuring an ultra-close 1cm macro focus capability, great for detailed close-ups.

In practical shooting scenarios, I found the HX90V’s zoom life-enhancing for travel, wildlife, and sports, allowing tight framing while keeping distance from subjects. The optical image stabilization compensates for camera shake effectively at long reach.

The TX7’s shorter zoom demands more physical closeness to subjects but benefits compactness and ease of carrying. Its macro performance is surprisingly excellent, allowing for detailed flower or insect shots without additional gear.

Lens sharpness: The HX90V maintains decent sharpness across the zoom range but suffers slightly at full telephoto edges - a common superzoom trait. The TX7’s fixed range lens is impressively sharp at the wide end, with some softness creeping in towards 100 mm.

Burst Shooting and Continuous Performance

Both cameras offer 10 fps burst shooting, but there are caveats. The HX90V supports continuous autofocus during bursts, improving chances of sharp images in action sequences. It excels here for sports or wildlife snapshots thanks to better buffering and processor speed.

The TX7 supports burst shooting at 10 fps but lacks continuous AF, making it less suited to moving subjects. Its buffer fills quicker, reducing sustained burst length.

Video Capabilities: Are Cinematic Aspirations Supported?

Surprisingly, both cameras manage 1080p Full HD video recording - but with different chops.

• HX90V supports 1080p up to 60 fps in AVCHD and XAVC S formats. It includes optical steady shot stabilization in video mode and records smooth motion, crisp detail, and fair low-light handling for casual videography.

• TX7 also shoots Full HD (1920x1080) at 60 fps but lacks advanced codecs and stabilization is optical but limited. Touchscreen focusing during video aids usability, but no microphone or headphone ports restrict professional audio input.

Neither camera offers 4K or advanced cinematic features, but for quick family clips or travel vlogs, both suffice.

Battery Life and Storage: How Long Can They Last Out There?

The HX90V uses the NP-BX1 battery pack, rated for roughly 360 shots per charge according to Sony specs. Real-world use with GPS and WiFi active tends to operate closer to 300 shots in mixed shooting. GPS tagging is a boon for travel photographers keen to geo-locate images.

The TX7 uses the NP-BN1 battery with Sony's lower rating (unlisted officially), generally around 210-250 shots per charge. Its lack of wireless connectivity means fewer battery hits from radio use, giving slightly longer standby times.

Both cameras take single SD card slots supporting SD/SDHC/SDXC formats, but the TX7 also takes Sony Memory Stick Duo cards - a bit of a legacy holdover.

Connectivity and Extras: Keeping Pace With Modern Needs

In 2015, the HX90V came equipped with built-in WiFi and NFC, streamlining image transfer and smartphone control - a huge convenience for quick sharing or remote shooting.

The TX7 from 2010 lacks any wireless connectivity but offers an HDMI output and USB 2.0 port for tethered transfer and playback.

The HX90V adds a built-in GPS module, something I found genuinely useful to automatically log your travel routes - especially if you tend to forget where you took that amazing sunset.

Both cameras have no microphone or headphone jacks, limiting audio control during video recording.

Durability and Build Quality

Neither model boasts weather sealing or ruggedized protection, which is an important consideration for outdoor or professional work.

Build quality-wise, the HX90V feels robustly constructed with a solid mix of metal and high-quality plastics. The TX7’s ultracompact body uses more plastic but remains sturdy enough for casual everyday use.
