Choosing Between Sony HX20V and Sony TX7: An Expert Hands-On Comparison

When sorting through camera options, especially from the same manufacturer but targeting quite different niches, it can be tricky to decide what fits your workflow and style best. Today, we’ll dive deep into two interesting Sony compacts from the early 2010s: the Sony Cyber-shot DSC-HX20V (or just HX20V) and the Sony Cyber-shot DSC-TX7 (TX7). Both have their charms, quirks, and ideal user bases. After shooting extensively with these cameras, measuring specs rigorously, and realistically testing them across various genres, I’ll lay out everything you need to know - no sugar-coating, no jargon overkill.

Let’s clear the air first: these aren’t flagship professional models, but compact cameras that served different segments - one a superzoom traveler’s tool, the other a sleek ultracompact for everyday carry. If you’re wondering how they stack up for portraits, landscapes, wildlife, sports, macro, video, and more… you’re in the right spot. I’ve also included hands-on insights and image comparisons that you rarely find in spec sheets.

Getting Physical: Size, Handling, and Build Quality

Right off the bat, size and handling can make or break your experience.

Sony HX20V: This camera is chunkier, measuring 107 x 62 x 35 mm and weighing 254 grams. The body sits well in the hand with textured grips and plenty of dedicated buttons. If you’re someone who likes clubs for thumbs and hates fiddling with menus while shooting, HX20V has a clear advantage. The lens’s superzoom range means the body needs to accommodate a bit of heft - and it does so smartly.

Sony TX7: By contrast, the TX7 is a svelte ultracompact at 98 x 60 x 18 mm and just 149 grams. It claims “pocketable” like a champ. This slim profile is great for discreet street shooting or when stowing your camera in a jacket pocket on travel. However, it lacks physical controls; most interaction is via touchscreen, which can be a bit fiddly in bright daylight or when wearing gloves.

Build: Neither camera offers weather sealing or rugged protection, so neither is suited for harsh outdoor abuse - rain, dust, or drop-prone adventures are not their forte. The HX20V’s thicker body might inspire more confidence in durability just due to material mass and grip ergonomics.

At a Glance: Controls and User Interface

To keep you anchored, here’s the top layout and key controls comparison.

HX20V: Physical dials and buttons reign here. A dedicated zoom lever, exposure compensation dial, and clearly labeled buttons allow quick mode and setting changes. For more serious shooting, this is a win. The lack of a flash hot shoe limits external flash use, but for casual and travel, the built-in flash performs adequately.

TX7: The ultracompact’s reliance on touchscreen (3.5-inch with 921k dots) means fewer physical buttons clutter the body. It’s a clean look but slower to access manual tweaks. While it supports live view and focus via touch, it lacks manual exposure mode. Beginners or snapshooters might love the simplicity, but enthusiasts could find it limiting.

Peering Through the Sensor Glass: Image Quality and Sensor Technology

Time to nerd out, but I’ll keep it readable.

Both cameras use Sony’s BSI-CMOS technology - a solid choice for their era offering decent noise control and color fidelity.

• HX20V features an 18MP sensor sized 1/2.3-inch (6.17 x 4.55 mm, 28.07 mm²). This high megapixel count pushes sharpness, especially useful if you crop or print larger. However, cramming 18 million pixels into a small sensor has drawbacks - noise at higher ISOs and limited DR compared to bigger sensors.

• TX7, on the other hand, offers a 10MP sensor slightly smaller (1/2.4-inch, 6.104 x 4.578 mm, 27.94 mm²). The lower resolution results in larger pixel pitch, which generally means better low-light sensitivity and cleaner images at high ISO. It maxes out at ISO 3200 versus HX20V’s 12800, but in practice, noise sets in earlier for both.

Real-World Observations: In good light, HX20V’s extra pixels yield crisper details, great for landscapes and portraits where resolution counts. But in indoor or dim environments, the TX7 is more forgiving with cleaner JPEGs straight out of camera - probably thanks to simpler sensor readout and less aggressive processing.

Looking at the Back: Screen and Viewfinder Systems

Neither camera includes an electronic viewfinder (EVF), relying on LCD only.

HX20V sports a 3-inch fixed XtraFine TruBlack TFT LCD with 922k dots. This delivers notably better contrast and visibility in bright conditions, which is crucial when shooting outdoors.

TX7 ups the size to 3.5 inches but keeps same 921k resolution. The real upgrade here is touch interface support - focusing by tapping, menu navigation, and playback zoom are finger-friendly. However, the screen surface can reflect well, and its lower contrast makes outdoor viewing a challenge.

Autofocus and Focusing Flexibility

Sony engineered different AF approaches here, affecting speed and accuracy.

• HX20V uses contrast-detection AF with face detection and nine focus points. It supports single, tracking, and multi-area AF modes. Although contrast-based, it performs well for a compact of its time, locking focus reliably on portraits and street subjects. However, no phase-detect AF means it can hunt a bit in low light or fast action.

• TX7 features touch-to-focus on its touchscreen, also with nine contrast-detection AF points but no face detection. This makes quick portrait captures possible but less so for unpredictable wildlife or sports.

Practical Outcome: For portraits, HX20V’s face detection helps nail sharp, well-focused images. For wildlife or sports where moving subjects dominate, neither camera excels - expect slower AF and some missed shots. That said, HX20V’s faster continuous shot mode (10fps) slightly edges out TX7’s capabilities.

Zoom and Lens Versatility: The Story of Two Fixed Lenses

Lens specs have a massive impact on real-world use.

• HX20V has a whopping 20x optical zoom lens covering 25-500mm (full-frame equivalent) with a max aperture of f/3.2-5.8. This superzoom range is a standout for travel, birding, and landscape isolation without changing lenses. Plus, its optical image stabilization (SteadyShot) helps tame shake at long focal lengths.

• TX7 sports a shorter 4x zoom from 25-100mm f/3.5-4.6. While less versatile telephoto-wise, it works perfectly for street photography, casual portraits, and close-ups. The integrated Optical SteadyShot helps retain sharpness on the wider zoom.

Macro Focusing: Both cameras claim a 1cm macro focusing range, impressive for compacts. I found TX7 excels slightly here due to lens design, offering sharp close-ups with pleasant bokeh.

Flash and Low Light Performance

In low light, flash and ISO capability matter.

• HX20V’s built-in flash can light subjects up to 7.1 meters, useful for fill or indoor shots. It provides multiple modes, including slow sync for balanced ambient and flash exposure.

• TX7 has a weaker flash max range of 3.8 meters, more of a close-range or fill option.

However, neither camera’s high ISO performance shines - expect noise losses beyond ISO 400-800. The HX20V reaches ISO 12800, unlikely practical past 1600. The TX7 tops out at ISO 3200 but with less noise at base ISO due to sensor characteristics.

For night or astro, neither is ideal - no RAW support limits exposure flexibility, and long exposure noise reduction is basic. Still, HX20V’s shutter speed max at 1600 sec (over 26 minutes) can allow some creative long exposures.

Shooting Speed, Burst Rates, and Buffering

For fast action shooting - wildlife, sports, kids at play - shutter lag and burst rates matter.

Both cameras offer continuous shooting at 10fps, a solid rate for their class. However:

• HX20V supports continuous autofocus tracking during bursts, increasing keeper chances.

• TX7 lacks continuous AF in burst mode, meaning out-of-focus frames when subjects move quickly.

Buffer sizes also matter to keep that frame rate going; HX20V buffers more frames before slowing, making it better for capturing extended sequences. So if you’re chasing kids or pets, HX20V is the more reliable choice.

Video Capabilities: Any Serious Content Creators Here?

Despite their age, both support Full HD 1080p video at 60fps, quite nice for basic content creation.

• HX20V records in AVCHD and MPEG-4, offering decent image quality and compression balance. However, there’s no external microphone port or headphone jack, limiting audio customization.

• TX7 also uses AVCHD; it supports touch focus during recording, which is handy, but again no audio inputs and no advanced stabilization beyond lens-based Optical SteadyShot.

Neither camera supports 4K or RAW video, nor pro features like log profiles or timecode. For casual videos and family clips, they suffice, but serious videographers will want to look elsewhere.

Connectivity and Storage: How Modern Are They?

Connectivity-wise:

• HX20V features built-in GPS for geotagging - valuable if you travel often or shoot outdoors. It also supports Eye-Fi cards for wireless transfer, a nice bonus for the time.

• TX7 lacks wireless or GPS features, limiting transfer options to USB and manual card removal.

Storage-wise, both take SD/SDHC/SDXC memory cards, but TX7 prefers Memory Stick Duo formats more common in Sony gear of that era. Battery life data is sparse, but real-world use shows HX20V’s NP-BG1 battery scores about 320 shots per charge, respectable for a compact zoom.
