Sony HX20V vs Sony TX66: A Detailed Hands-On Comparison for Serious Buyers in 2024

When scouting for a compact digital camera in 2024, the Sony Cyber-shot DSC-HX20V and DSC-TX66 stand as enduring options from the early 2010s. Both packed surprisingly advanced features for their time, with 18MP BSI-CMOS sensors and full HD video capabilities, yet they target distinctly different user profiles. I’ve spent hours with each, pushing their limits across varied photographic disciplines - from intimate portraits to demanding wildlife scenes - to unearth what separates these two 1/2.3-inch sensor compacts.

If you’re a photography enthusiast seeking a compact yet capable superzoom versus someone who prioritizes pocketability and modern touchscreen convenience, this comparison will clarify which Sony model best aligns with your creative ambitions. Below, I dissect their core hardware, image quality, shooting experience, and value proposition with hands-on insights and technical depth - balanced and straightforward to guide both experienced photographers and curious beginners alike.

Physical Design and Ergonomics: Size vs. Handling Balance

Stephen Covey famously said, “Begin with the end in mind” - and the HX20V and TX66 clearly do. The HX20V is the larger, more substantial, superzoom compact of the two, boasting a generous 25-500mm (20x) zoom. By contrast, the TX66 offers a sleeker, ultracompact design with a modest 26-130mm (5x) range.

Visually and in hand, the difference is stark:

• The HX20V weighs 254g and measures roughly 107×62×35mm - giving confident grip and control but reducing pocketability.
• The TX66 is featherlight at 109g and ultra-slim with dimensions of 93×54×13mm, easily slipping into a jacket or purse.

Both cameras feature fixed lenses, but only the HX20V incorporates a slight front grip for better one-handed stability - a boon for longer telephoto framing. The TX66’s slick aluminum body, while elegant, demands practice to avoid camera shake.

On the control front, the HX20V opts for conventional physical buttons and dials ensuring tactile feedback, whereas the TX66 integrates a responsive 3.3-inch OLED touchscreen (more on that soon).

Next, let's examine their compactness side by side and how that influences shooting styles:

• The HX20V presents well-spaced buttons, making it easier to operate under duress (e.g., fast-action shoots).
• The TX66’s minimalist top controls complement its touchscreen but may challenge those who prefer manual dials for quick setting adjustments.

In summary, if you prioritize ergonomics and superzoom reach, HX20V is structurally superior. For ultraportable everyday carry, TX66 stands out - though at the expense of telephoto flexibility and some manual control finesse.

Imaging Core: Sensor, Lens, and Image Quality Deep Dive

At the heart of both models lies the same sensor technology - an 18MP backside-illuminated CMOS sized at 1/2.3" (6.17 x 4.55 mm sensor area). Despite the sensor similarity, differences in lens construction, optics, and image processing produce distinct photographic results.

Consequently, their shared sensor specs look like this:

Key technical notes:

• Both feature an antialiasing filter, which slightly softens fine detail but reduces moiré.
• Native ISO ranges extend up to ISO12800, though practical low-light usability caps nearer ISO1600.
• The HX20V's lens is a versatile but slower F3.2-5.8 aperture, while the TX66’s lens is slightly faster at F3.5-4.8 but with a shorter zoom range.

Image Quality Analysis

During controlled laboratory shootouts and real-world testing:

• Dynamic Range was modest and nearly equal between the two - both struggling slightly with extreme highlight retention, especially in harsh sunlight.
• High ISO Noise control favored the TX66 marginally, thanks to its OLED screen encouraging better exposure confidence.
• Color Reproduction was warm and pleasant on both, but the TX66’s sensor processing delivered slightly richer saturation and contrast out of the box.
• Sharpness was a toss-up; the HX20V retained better detail at telephoto lengths due to lens design but had more visible chromatic aberrations on edges.

The net takeaway - both are capable shooters for casual and enthusiast use, but neither will match APS-C or full-frame rivals in ultimate image fidelity; their small sensor size imposes this practical ceiling.

Display and User Interface: OLED Touchscreen vs. LCD Clarity

Display technology profoundly affects composition and evaluation accuracy. Sony opted for different screen techs here:

• The TX66’s 3.3" OLED touchscreen, at 1230k-dot resolution, provides vivid colors, deep contrast, and finger-friendly responsiveness. I found this especially useful for street photography and quick menu navigation.
• The HX20V’s 3" TFT LCD is bright but less contrasty and lacks touch; its 922k-dot resolution is decent but feels dated compared to the OLED.

Both lack electronic viewfinders, demanding reliance on their rear screens even in bright outdoor sunlight - where the TX66’s OLED is more watchable due to superior black levels and anti-reflective coating. The HX20V can struggle under direct sun.

From an interface standpoint:

• The TX66’s touchscreen enables intuitive features like touch-to-focus and touch shutter, enhancing casual shooting speed.
• Conversely, the HX20V’s physical buttons and dials encourage more deliberate manual settings adjustments - even offering manual focus rings - better suiting enthusiasts and occasional manual shooters.

Autofocus and Speed: Tracking and Burst Shooting

Autofocus is critical in capturing fleeting moments, and while both cameras utilize Sony’s BIONZ processor paired with 9-point contrast-detection AF systems, their performance diverges under different scenarios.

• Both cameras provide single, selective, center-weighted, and tracking AF modes, and include face detection.
• However, the HX20V supports 9 autofocus points, while the TX66's exact AF point count is unspecified but simplified due to its touchscreen.

In practical use:

• The HX20V’s AF locks reliably in bright, controlled environments - especially at wide zoom - but hunting arises at longer telephoto lengths or in low light.
• The TX66 benefits from touchscreen-based AF point selection, which occasionally quickens focus-lock on moving subjects despite having fewer focus points.
• Both offer continuous shooting at 10 fps, but buffer limitations quickly slow longer bursts.

For sports or wildlife shooting, however, neither camera fulfills professional standards - they are optimized more for casual action capture rather than rapid-fire tracking or deep subject recognition.

Lens Range and Optical Stabilization: Reach vs. Compactness

Lens capability directly influences photographic versatility:

• Sony HX20V’s 20x superzoom (25-500mm equiv.) vastly outperforms the TX66’s 5x zoom (26-130mm) for wildlife, sports, and distant landscapes.
• Both use optical image stabilization, crucial given these are small-sensor compacts prone to camera shake - the HX20V’s stabilization feels a tad more robust, likely compensating for the much longer telephoto reach.

Such extended reach, though, means the HX20V often requires a steady hand or tripod to secure sharp images at the extreme end. The TX66’s shorter range sacrifices telephoto flexibility for pocket-size and quicker framing.

Photo Genres: Real-World Strengths and Weaknesses

Here I assess how each camera fares across various popular photographic disciplines, informed by extensive test shoots.

Portrait Photography

Both deliver pleasing skin tones largely thanks to Sony’s color science and face detection AF. The HX20V’s broader zoom enables moderate background compression and subject isolation at longer focal lengths, but the slower aperture limits bokeh quality compared to larger-sensor cameras.

The TX66’s touchscreen facilitates touch-to-focus on eyes, a subtle advantage for casual portraits. Neither offers advanced eye-detection AF or refined bokeh rendering.

Landscape Photography

Both capture ample detail at wider focal lengths. However, the HX20V’s extreme zoom gives additional creative framing options for distant mountain ranges or cityscapes.

Neither camera is weather-sealed, a factor to consider when exploring rough terrain or inclement weather.
