When it comes to physical presence, the Sony RX10 and TX66 are worlds apart - both in dimensions and in tactile feel.

The RX10 is a hefty, SLR-styled bridge camera with dimensions of 129 x 88 x 102 mm and a weight north of 810 grams. Its solid build, combined with weather sealing, caters to photographers demanding durability in diverse environments. The pronounced grip and ergonomic button placements make extended handheld use comfortable, especially when zooming or tracking fast-moving subjects.

Contrast this with the TX66’s ultracompact form factor - 93 x 54 x 13 mm at a featherweight 109 grams. It slips effortlessly into a pocket or small bag, perfect for street or travel photography where discretion and portability matter most.

Though the RX10’s robust ergonomics provide manual control precision and a confident hold, the TX66’s slim profile sacrifices substantial grip but gains an ultra-portable convenience that casual users and minimalists will appreciate.

Top Controls and Interface: Speed of Access in the Field

The layout of controls can make or break shooting spontaneity. Let’s peek on top.

On the RX10, Sony went big with traditional dials for aperture and shutter priority, exposure compensation, and a well-snug shutter button nestled within a zoom lever. The camera features 25 focus points and a tilting 3" WhiteMagic screen, complimented by an electronic viewfinder (EVF) boasting 1,440k dots and 100% coverage - vital for sunlit outdoor shooting.

The TX66, however, takes a minimalistic route. With no EVF and a fixed 3.3" OLED touchscreen, its physical buttons are sparse. The touchscreen compensates by offering swift AF target selection, albeit with less tactile feedback. The camera’s lack of manual exposure modes confines creative control mostly to automatic or program modes.

For photographers accustomed to tactile dials and quick adjustment, the RX10 offers a professional-grade interface. The TX66 bets on simplicity and touchscreen versatility, which while less precise, enhances speed for casual shooting.

Sensor Size and Image Quality: The Core of Performance

Perhaps the most defining technical difference between these cameras is their sensor real estate.

The RX10 features a 1-inch BSI-CMOS sensor measuring 13.2 x 8.8 mm (116.16 mm²), delivering 20 megapixels. This sizeable sensor for a superzoom camera enables superior dynamic range (12.6 EV), impressive color depth (22.9 bits), and an excellent low-light ISO performance verified by DxOMark scoring it 69 overall.

In contrast, the TX66 packs a far smaller 1/2.3" sensor (6.17 x 4.55 mm, 28.07 mm²) with 18 megapixels. While respectable for an ultracompact, its performance in low light and dynamic range significantly lags behind the RX10, attributable to its physical constraints.

As a result, expect the RX10 to excel in image quality under demanding lighting - retaining highlight and shadow nuances and delivering rich, noise-free images at high ISOs. The TX66 performs well in daylight but struggles in low-light or scenes needing wider dynamic range.

Display and Viewfinder: Composing Your Shots

Framing your shot is a tactile experience, influenced heavily by the camera’s screens and viewfinders.

The RX10’s tilting 3-inch WhiteMagic screen, though not a touchscreen, boasts sharp resolution (1,290k dots) and brightness that holds up outdoors. This, coupled with its high-resolution EVF, caters to precise composition whether using the viewfinder or the LCD.

Conversely, the TX66 forgoes an EVF and leverages a larger 3.3-inch XtraFine TruBlack OLED touchscreen. While colors are vibrant and viewing angles excellent, the fixed nature and the lack of eye-level framing may challenge those shooting in bright sunlight or fast-paced environments.

For tripod or handheld static shooting, TX66’s touchscreen enables rapid focus area selection and menu navigation, but for dynamic or action photography, the RX10’s EVF offers clear advantages.

These shots were taken in a range of conditions - a portrait indoors, a sprawling landscape at sunset, and a quick street scene.

• Portraits by the RX10 demonstrate nuanced skin tones and smooth, natural bokeh rendered by its fast F2.8 fixed zoom lens (24–200mm equivalent).
• TX66 portraits are passable for casual use but show weaker subject isolation and less pleasing skin tone gradation, partly due to smaller sensor and narrower apertures.
• Landscape shots from the RX10 retain excellent detail in shadowed trees and bright skies, with vivid but believable colors.
• TX66’s landscapes appear more compressed in dynamic range, with washed-out highlights and some noise creeping into shadows.
• Street frames illustrate the TX66’s agility and compactness but also its limits in low-light focusing compared to the RX10 which locks focus quicker and maintains clarity even at twilight.

Autofocus Systems: Precision and Speed Under Pressure

In rapid shooting contexts such as wildlife or sports, autofocus performance is paramount.

The RX10 employs 25 contrast-detection autofocus points with single, continuous, selective, and face detection modes, but lacks phase detection or animal eye AF. Its continuous shooting rate tops out at 10 frames per second, quite respectable for its class.

The TX66 offers fewer details on focus points but supports face, tracking, and single AF with contrast detection. Continuous shooting is capped at 10 fps as well but is slowed by limited buffer depth and less responsive AF in challenging lighting.

In practical testing with fast-moving subjects - birds in flight, cyclists zooming past - RX10’s AF consistently acquires and tracks more quickly and accurately, enabling higher keeper rates. The TX66’s AF works best in good light but will struggle to maintain sharpness during bursts or erratic motion.

Zoom Lenses and Optical Performance

Optics matter enormously, especially for zoom enthusiasts or travel photographers.

The RX10 has a fixed 24-200 mm F2.8 constant aperture Zeiss Vario-Sonnar T* lens. This means silky smooth bokeh at telephoto focal lengths and reliable exposure throughout the zoom range. Optical image stabilization helps maintain sharpness throughout its range.

The TX66’s lens spans a 26-130 mm zoom with a variable maximum aperture of F3.5-4.8. While compact and adequate for snapshots, the narrower aperture limits depth of field control and low-light capture.

The RX10’s lens quality remains crisp edge-to-edge with minimal distortion or chromatic aberration, upholding its superzoom promise. The TX66, more modest optically, introduces softness and chromatic fringing at extremes, acceptable for casual but not critical use.

Battery Life and Connectivity: Staying Powered and Connected

For long days shooting or on-the-go upload, battery and connectivity are key.

The RX10 operates on a Sony NP-FW50 battery, rated at 420 shots per charge, which in real life translates to a comfortable day of mixed shooting. It features built-in Wi-Fi with NFC for easy wireless file transfer, HDMI for external monitors, and microphone and headphone ports appealing to videographers.

Compared to that, the TX66’s NP-BN battery yields around 250 shots per charge - half that of the RX10. Connectivity is limited: no Wi-Fi or Bluetooth, only USB 2.0 and HDMI ports. This restricts workflow flexibility, especially for users accustomed to instant sharing or remote control apps.

Weather Sealing and Durability: Ready for the Outdoors?

The RX10 is weather sealed - resistant to dust and moisture - making it a reliable companion for outdoor shoots in varied conditions. While not shockproof or freezeproof, its rugged design inspires confidence compared to typical compacts.

The TX66, with its slim and sleek body, offers no environmental sealing. It’s best relegated to fair weather and gentle usage conditions.

Video Features: Capabilities for the Cinematographer

For hybrid shooters blending stills and video, the two models have notable differences.

The RX10 shoots Full HD 1080p at 60, 60i, and 24 fps with AVCHD and MPEG-4 codecs. Crucially, it sports microphone and headphone jacks, giving you manual audio input and monitoring - a boon for serious videographers. Optical stabilization aids in smooth handheld footage.

The TX66 offers 1080p at 60 fps too but lacks audio ports and has more limited codec options. Stabilization is present but less advanced.
