Physical Design and Handling: Size, Ergonomics, and Controls

At first glance, the Sony RX10 and TX5 could not be more different physically - the RX10 is a robust, SLR-like bridge camera designed with serious photographers in mind, while the TX5 is a sleek, pocketable ultracompact intended for casual, everyday shooting even under tough conditions.

The Sony RX10 weighs a substantial 813 grams and measures 129 x 88 x 102 mm. Its design mimics the traditional DSLR style with a pronounced grip, an electronic viewfinder (EVF), and a tilting 3.0-inch WhiteMagic LCD with 1,290k-dot resolution. This combination offers excellent handling stability, especially when using its constant F2.8 zoom lens and in demanding scenarios like wildlife or sports photography. Its large size accommodates a top control panel and substantial physical dials, allowing intuitive and rapid manual adjustments, crucial for professional workflows.

Conversely, the Sony TX5 tips the scale at just 148 grams and measures a compact 94 x 57 x 18 mm. Its slim ultracompact profile fits comfortably in any pocket or small bag - a major advantage for street and travel photographers prioritizing mobility and stealth. However, the TX5’s fixed screen and lack of viewfinder put it at a usability disadvantage in bright outdoor conditions or for those who prefer a more traditional framing approach. The touch-sensitive 3.0-inch screen is modestly sharp at 230k dots, significantly less detailed than the RX10’s display.

Ergonomically, the RX10’s top panel reveals dedicated dials for shutter speed, aperture, and exposure compensation, complemented by configurable function buttons. The TX5’s controls, meanwhile, are minimalistic with no mode dial or manual exposure options, reflecting its casual user base.

Sensor and Image Quality: The Heart of the Difference

The most critical divergence between these two cameras lies in their sensor technology and associated image quality.

The Sony RX10 boasts a large 1-inch BSI-CMOS sensor measuring 13.2 x 8.8 mm with an effective resolution of 20 megapixels. This sensor size, roughly four times larger in area than the TX5’s, significantly elevates the camera’s potential image quality - enhancing dynamic range, low-light performance, color depth, and noise control. Sony’s Bionz X image processor further complements the sensor to deliver rich tonal gradations and accurate skin tone reproduction - vital for portrait photographers aiming for natural yet punchy results.

DxOMark rates the RX10 highly with a color depth of 22.9 bits, a dynamic range of 12.6 EV, and a low-light ISO performance scoring at 474, indicating strong performance up to ISO 12800 native (expandable to ISO 25600). The inclusion of an anti-aliasing filter helps reduce moiré artifacts while maintaining sharpness.

In direct comparison, the Sony TX5 utilizes a much smaller 1/2.4-inch (6.1 x 4.6 mm) sensor with 10 megapixels resolution. This sensor size inherently limits its performance in terms of dynamic range - similar compact cameras struggle with blown highlights and loss of shadow detail - and noisy images at higher ISOs. Its maximum ISO tops out at a modest 3200 with no extended range support, and raw file capture is not supported, restricting post-processing flexibility critically.

Autofocus System and Speed

Autofocus (AF) technology is a decisive factor depending on your shooting style, with different needs for portrait, wildlife, or sports photography.

The Sony RX10 incorporates a versatile contrast-detection AF system with 25 focus points and face detection. Although lacking phase-detection AF, its processing algorithm provides fast and reasonably accurate autofocus in good lighting conditions and maintains decent continuous focus tracking during its 10 fps burst mode. However, compared to more modern phase-detection or hybrid AF systems, its tracking of fast-moving subjects - such as birds in flight or athletes - is not cutting edge but sufficiently reliable for most enthusiast use.

By contrast, the Sony TX5 features 9 focus points relying exclusively on contrast detect AF, which is relatively slow and occasionally hunts in low-light or low-contrast situations. There is no continuous autofocus mode, nor animal eye AF, making the TX5 impractical for fast-paced shooting or wildlife photography. However, for static subjects and travel snapshots, the AF system is snappy enough to ensure user satisfaction.

Build Quality and Weather Resistance

Here, both cameras reflect their intended uses but in divergent ways:

The RX10, despite its DSLR-style design, offers only partial environmental sealing - not fully waterproof or dustproof, and without shock or crush resistance. It is designed primarily for semi-professional photographic versatility indoors and outdoors rather than extreme environments.

In stark contrast, the Sony TX5 is fully ruggedized: waterproof down to 10 meters, dustproof, shockproof from drops up to 1.5 meters, and freezeproof down to -10°C. Such robustness makes the TX5 a superb companion for adventure photographers, underwater excursions, or family outings where the risk of damage is higher.

Display and Viewfinder Interface

Handling and reviewing compositions are markedly different experiences on these cameras.

The Sony RX10’s LCD benefits from a bright 3-inch, tilting screen with excellent resolution and WhiteMagic technology, enhancing outdoor visibility. The electronic viewfinder (EVF), with 1,440k-dot resolution, offers 100% frame coverage and 0.7x magnification, providing a traditional and accurate composition method comparable to entry-level DSLRs.

The TX5 lacks an EVF altogether and offers only a fixed 3-inch 230k-dot touchscreen, which can be difficult to see in bright daylight. While its touchscreen enables quick navigation and focus point selection, it lacks the tactile precision of physical controls found on more advanced cameras like the RX10.

Lens and Zoom Capabilities

The lens systems of both cameras reveal their intended usage profiles quite clearly.

The RX10’s fixed zoom ranges from 24-200mm equivalent (8.3x zoom) with a constant wide aperture of F2.8 throughout the zoom range, representing an excellent optic suitable for low-light and shallow depth-of-field effects. This large-aperture, versatile zoom is ideal for portraits (creating creamy bokeh), landscapes, wildlife distances, and sports action within reach.

Conversely, the Sony TX5 offers a more modest 25-100mm equivalent (4x zoom) with a variable aperture from F3.5 at wide to F6.3 at telephoto, limiting its low-light capabilities, background separation, and overall optical versatility. This lens is adequate for casual snapshots and general travel photography, but not for demanding artistic control.

Buffer and Continuous Shooting Performance

Both cameras provide respectable continuous shooting modes tailored to their markets.

The RX10’s 10 fps continuous shooting capability is commendable for a bridge camera with large sensor and full manual control, aiding in capturing fast action in sports and wildlife.

The TX5 matches this with 10 fps but without autofocus tracking or exposure adjustments during bursts, limiting usability for fast-moving subjects.

Battery Life and Storage

Battery life is critical when shooting on-location or traveling.

The Sony RX10 uses the NP-FW50 battery lasting approximately 420 shots per charge - above average for a bridge camera, sufficient for a day’s shoot with yet room to carry spares. It supports SD cards including SDHC and SDXC, Memory Stick formats, stored in a single slot.

The TX5 relies on the NP-BN1 battery, with less formalized rated capacity (Sony lists no exact shot counts), but in practice it performs modestly, suitable for casual outings rather than long professional sessions. Storage is similarly single slot supporting SD and Memory Stick formats, with slightly fewer file size demands due to smaller megapixel count.

Connectivity and Wireless Features

The RX10 supports some wireless connectivity options including built-in Wi-Fi and NFC for instant sharing and remote control, increasingly important for social media workflows and wireless tethering.

The TX5 offers no wireless connectivity, limiting it to cable transfers via USB or HDMI for external displays.
