Sony RX100 VA vs Sony TX55: A Hands-On Comparison From My Test Bench

In the ever-evolving world of digital cameras, Sony offers a diverse lineup ranging from pocket-sized point-and-shoots to professional compacts. Two models in particular, the Sony Cyber-shot DSC-RX100 VA (hereafter RX100 VA) and the Sony Cyber-shot DSC-TX55 (TX55), represent vastly different segments within Sony’s compact camera offerings. When considering a compact camera purchase - even in this era of smartphones and mirrorless giants - it’s essential to understand what each option can do in real-world scenarios.

Having spent over 15 years in camera testing, I’ve put these two side by side, scrutinizing their strengths, weaknesses, and ideal use cases. This hands-on comparison cuts through spec sheets and marketing speak to evaluate what really matters: practical photographic performance and value-for-money.

Let’s unpack what separates the RX100 VA, a large sensor compact announced in 2018, from the ultra-portable TX55 from 2011, and see who comes out on top depending on your photography needs.

Getting a Feel: Size, Ergonomics & Controls

First impressions matter, and cameras are no exception. Handling comfort and ease of control significantly affect shooting experience, especially for extended sessions.

The RX100 VA is a large sensor compact with serious photo chops but surprisingly pocketable dimensions. The TX55, meanwhile, is an ultra-compact with a slim, minimalist design tailored for grab-and-go convenience.

You can immediately see the size differences - RX100 VA is chunkier and more substantial, measuring 102x58x41mm and weighing about 299g. The TX55 is a featherweight champ at 109g and just 13mm thick, super easy to slip into tight pockets or small handbags.

Top-down, the RX100 VA features a well-thought-out control layout with dedicated dials and buttons suited for manual adjustments. By contrast, the TX55 keeps it simple with minimal physical controls, relying heavily on its touchscreen interface.

From personal testing, I appreciate the RX100 VA’s clubs-for-thumbs approach - large buttons and a tactile dial feel much better for enthusiast shooters who want quick access to settings like aperture, shutter speed, and exposure compensation. The TX55’s interface favors casual shooters or absolute beginners who want straightforward point-and-shoot ease.

Ergonomics verdict: RX100 VA takes the win for serious photographers; TX55 excels if you want ultra-compact minimalism with straightforward usability.

Sensor and Image Quality: The Heart of the Matter

Size isn't everything - sensor technology plays the biggest role in image quality. Let’s dive into what you’re really paying for.

• RX100 VA: 1-inch type BSI-CMOS sensor, 20 megapixels, max ISO 12800 native (expandable to 25600), front-illuminated design to maximize light gathering.
• TX55: Much smaller 1/2.3-inch BSI-CMOS sensor, 16 megapixels, max ISO 3200 native.

Those numbers tell part of the story: the RX100 VA’s sensor area (116.16 mm²) is more than four times larger than the TX55’s 28.07 mm². Larger sensors correlate to superior dynamic range, low-light performance, and less noise, all critical factors for enthusiasts and pros alike.

In controlled testing with RAW files, the RX100 VA delivers noticeably cleaner details at higher ISOs, with more subtle gradations in shadows and highlights. The TX55's images, while decent for casual snapshots, begin to show noise texture and loss of detail above ISO 800, even before the max ISO of 3200.

Portrait photographers will value how the RX100 VA softly isolates subjects with natural skin tone rendering and the ability to produce attractive background blur (thanks in part to its fast f/1.8 lens aperture). The smaller sensor and slower lens (f/3.5-4.8) on the TX55 limit bokeh potential and shallow depth-of-field control.

Image quality takeaway: The RX100 VA decisively outperforms in image quality. If image fidelity and low-light work are priorities, the advanced sensor makes a critical difference.

Live View and LCD Screen Usability

Composing and reviewing shots relies heavily on the LCD and viewfinder setup.

The RX100 VA features a 3-inch tilting LCD at 1229k dots resolution - bright, sharp, and flexible for shooting at awkward angles or selfies (it even boasts a selfie mode). It also packs an electronic viewfinder (EVF) with 2359k dots resolution and 100% coverage, offering a clear, lag-free framing experience under bright sunlight.

Contrastingly, the TX55’s 3.3-inch fixed OLED touchscreen with roughly the same resolution focuses on vibrant colors and good contrast but lacks an EVF - a drawback for those shooting in bright environments where LCD glare becomes an issue.

From experience, the RX100 VA’s tilting screen and EVF combo substantially enhance compositional flexibility and precision, making it better suited for enthusiasts and professionals who demand accuracy in framing under various lighting conditions.

On the other hand, I found the TX55’s touchscreen intuitive for casual use and fast menu navigation but limiting if you want to micro-adjust settings or shoot consistently outdoors.

Autofocus Systems: Speed, Accuracy, and Tracking

Now we get to the nuts and bolts of performance - the autofocus (AF) system.

• The RX100 VA employs a hybrid AF system with 315 phase-detection points, vastly improving autofocus tracking speed and accuracy. It supports face detection, eye AF, and continuous AF during bursts, which is essential for portraits capturing fleeting expressions or action shots.

• The TX55 has a simpler 9-point contrast-detection autofocus, lacking phase-detection sensors or advanced tracking features. Face detection is absent, limiting precision in portraits.

In practical tests, the RX100 VA nails focus quickly, even in low light, locking onto eyes reliably and maintaining tracking on moving subjects. The TX55 often hunts in dimmer environments and can lose focus on fast-moving scenes.

For wildlife or sports photographers needing responsive AF during sequences, the RX100 VA is leagues ahead - its burst shooting rate of up to 24 fps combined with fast AF makes a winning combo for capturing decisive moments.

Lens Capabilities and Macro Focus

The RX100 VA comes with a fixed 24–70 mm equivalent lens, bridging wide-angle to short telephoto with a bright maximum aperture range of f/1.8 to f/2.8. This lens versatility allows creative framing from environmental portraits to street candids.

The TX55 has a more extensive 26–130 mm equivalent zoom, offering a longer reach but with slower apertures from f/3.5 to f/4.8, meaning less light gathering and more depth-of-field. For casual zooming, this extended range can help, but image quality declines at the telephoto end due to the smaller sensor and lens constraints.

Macro performance is notable: the TX55 can focus as close as 3 cm, slightly better than the RX100 VA’s minimum 5 cm. However, the RX100 VA’s stabilized lens and better image processing result in sharper and more detailed close-ups despite the marginally longer minimum focus distance.

Burst Shooting and Buffer Depth

Speed matters, especially in wildlife and sports. The RX100 VA offers an impressive 24 fps burst with continuous autofocus - a feature often found in higher-end mirrorless cameras, making it a mini workhorse in a compact body.

The TX55’s burst maxes out at a modest 10 fps, fixed-focus during burst mode, and a limited buffer which leads to early slowdowns in continued shooting.

For capturing fast-paced moments, the RX100 VA clearly holds the advantage, giving more options for action photographers.

Weather Sealing and Build Quality

Neither camera offers weather sealing, dustproofing, or rugged features. Both require delicate handling and extra care outdoors.

Build quality-wise, the RX100 VA feels significantly more robust with metal chassis components and a better grip, instilling confidence during all-day shoots. The TX55's plastic shell complements its slim profile but can feel more fragile under intensive use.

Video Features and Multimedia

Video capabilities can sway some users. Let’s compare.

The RX100 VA records 4K UHD video at 30p, encoding at up to 100 Mbps in XAVC S format. It offers standard full HD (1080p) frame rates up to 60p, clean HDMI out, and supports linear PCM audio, although it lacks external mic and headphone jacks.

The TX55 only manages 1080p video at 60 fps max, using AVCHD and MPEG-4 codecs. No 4K, no external audio options.

Neither camera features in-body stabilization for video, though optical image stabilization helps smooth handheld shooting.

For casual video capture, the TX55 suffices, but content creators and vloggers will appreciate the RX100 VA’s expanded video specs and superior image quality.

Connectivity and Storage Options

Wi-Fi and NFC wireless connectivity come built into the RX100 VA, enabling easy image transfer and remote control via a smartphone app. The TX55 lacks Wi-Fi but supports Eye-Fi cards for wireless workflow, which is increasingly dated technology.

Storage-wise, the RX100 VA uses full-sized SD cards, including SDHC and SDXC classes, facilitating faster write speeds and higher capacities. The TX55 is limited to microSD or Memory Stick Micro cards.

Battery Life and Practical Considerations

Despite the RX100 VA powering a larger sensor and EVF combo, battery life clocks in at around 220 shots per charge using the NP-BX1 battery. Not exceptional, but manageable if you carry spares.

The TX55 surprisingly stretches up to 250 shots per battery cycle, aided by its smaller sensor and lack of power-hungry EVF.

If on long trips without charging options, the TX55 might edge out in sheer endurance, but the RX100 VA’s superior image quality and feature set demand a power pack backup.

Price-to-Performance: Where’s the Sweet Spot?

Currently, the RX100 VA lists around $998, while the TX55 can be found near $350 on the used or discounted market.

While the RX100 VA is nearly triple the price, its remarkable image quality, advanced autofocus, and 4K video justify its premium to enthusiasts and semi-pros looking for an all-around compact capable of serious work.

The TX55 appeals to budget-minded beginners or casual shooters seeking a neat pocket camera for day-to-day snaps or travel, especially if high resolution or advanced features aren’t critical.
