Sony RX100 VI vs Sony TX1: A Hands-On Comparison of Two Iconic Sony Compacts

When it comes to portable cameras, Sony has been a force for innovation across decades - from early ultracompacts to today’s large sensor compacts that push the boundaries of image quality and versatility. In this deep-dive comparison, I put the Sony RX100 VI (2018) head-to-head with the Sony TX1 (2009) to explore how far technology has progressed and, more importantly, what each delivers in real-world photography.

While both cameras share Sony’s mastery in optics and imaging, they represent different eras, ambitions, and user needs. Over hundreds of hours testing cameras with sensors ranging from tiny to medium format, I've developed insight into what truly matters - from sensor design and autofocus to ergonomics and lens versatility. Let’s unpack these two models in a way that brings clarity to enthusiasts and even pros considering pocketable excellence.

Size, Handling & Ergonomics: From Slim Ultracompact to Feature-Rich Powerhouse

Physical size and ergonomics remain the first tangible difference, almost shouting from the specs. The Sony TX1 is a classic ultracompact that tucks into any pocket effortlessly, measuring a mere 94 × 58 × 17 mm and weighing just 142 grams. In contrast, the RX100 VI is a larger, more substantial large-sensor compact at 102 × 58 × 43 mm and weighing 301 grams. This added bulk translates to greater handling comfort and a wider feature set, but sacrifices pocket-friendliness.

I appreciate the RX100 VI’s sculpted grip and robust body that make prolonged shooting practical. Meanwhile, the TX1, with a slim profile and fixed lens, favors snapshooters valuing nimbleness and discretion. The TX1 is great for quick street photography where attention must stay subtle, but the RX100 VI improves stability especially when working with its long telephoto reach.

On top of size, physical controls differentiate the experience further:

The RX100 VI sports a sophisticated control layout including a customizable dial, mode dial, and a pop-up electronic viewfinder (EVF). These are significant for pros and enthusiasts who demand quick access to settings on the fly - a real productivity gain. The TX1 offers a minimalistic button set, relying more on menus with no viewfinder, so composing under bright skies relies solely on its fixed 3-inch LCD.

Speaking of screens...

Displays and Viewfinders: An Interface From Different Worlds

The RX100 VI features a 3-inch tilting touchscreen with 1229k-dot resolution (a substantial upgrade over basic screens), designed to provide flexibility for high and low-angle shooting as well as selfie framing. Its built-in EVF boasts a crisp 2.35M-dot OLED, affording 100% coverage and a sharp preview - essential for precise manual focus or bright light situations.

The TX1, meanwhile, offers a fixed, non-touch 3-inch LCD at 230k-dot resolution - almost a relic by today’s standards. Without any EVF, composing outdoors can be challenging, and menu navigation feels dated. However, this simplicity may appeal to casual users who prioritize uncomplicated operation.

The RX100 VI’s interface is clearly designed for photographers who want control and feedback; the TX1 caters more to casual usage.

Sensor Technology and Image Quality: Quantum Leaps in Sensor Size and Resolution

Here lies one of the most significant divides between these cameras - and a cornerstone of image quality advances over the past decade.

The RX100 VI features a 1-inch back-illuminated CMOS sensor measuring 13.2 × 8.8 mm with 20 megapixels of resolution and an anti-aliasing filter. Backside illumination (BSI) improves low-light sensitivity and dynamic range. It supports 125 ISO minimum native and maxes out at 12,800 ISO, with an extended boost to 25,600 ISO for even darker scenes.

In stark contrast, the TX1 uses a much smaller 1/2.4" BSI CMOS sensor sized 6.1 × 4.6 mm with just 10 megapixels resolution and the same anti-aliasing filter. Its native ISO tops out at a modest 3200. The sensor area difference is immense - roughly 4 times the size for the RX100 VI.

These differences are visible not only on paper but critically affect image quality:

In hands-on testing, the RX100 VI delivers cleaner files with better color reproduction and far better noise performance above ISO 1600. The dynamic range allows you to recover detail in shadows and highlights effectively, ideal for demanding landscape or portrait work. The TX1’s smaller sensor, while respectable in good light, exhibits early noise buildup and limited flexibility in challenging lighting.

Resolution matters, too: The RX100 VI’s higher 5472 × 3648 pixels bring more cropping freedom and sharpness in prints, while 3648 × 2736 pixels on the TX1 restrict output size.

The takeaway? The RX100 VI’s advanced sensor makes it a true large sensor compact, best for enthusiasts and professionals needing image quality beyond smartphone levels. The TX1 targets casual shooters who want steady, simple images for social sharing without fuss.

Lens and Optical Versatility: Zoom and Aperture for Real-World Use

Another stark difference appears in the lens design and focal length range, which shape which genres the cameras can tackle.

The RX100 VI sports a fixed zoom lens with a broad 24-200mm (equivalent) focal range - an 8.3× zoom - offering flexibility from wide-angle landscapes to moderate telephoto portraits and compression. Its aperture ranges F2.8 at wide angle, closing to F4.5 at 200mm. This fast-ish wide end is crucial for low light and controlling depth of field.

On the flip side, the TX1 has a 35-140mm equivalent zoom (4× zoom) with a slower aperture of F3.5-4.6. While reasonably versatile, it’s much more limited in reach and optical speed.

Because the RX100 VI lens is engineered with Zeiss optics and Sony’s advanced coatings, it produces consistently sharp images with minimal distortion and flare - even wide open. The TX1 lens suffers from some softness at telephoto ends and chromatic aberration that’s noticeable in high-contrast scenarios.

For portrait shooters, the RX100 VI's aperture and tele reach make a bigger impact - you get more pleasing bokeh and subject isolation coupled with sharp eye detection autofocus.

Speaking of autofocus...

Autofocus Systems and Speed: Precision Meets Responsiveness

In my extensive autofocus testing routines, I’ve learned that phase detection autofocus (PDAF) combined with contrast detection yields the best hybrid results - fast and accurate.

The RX100 VI comes with 315 phase-detect AF points covering a wide frame area, backed by contrast detection. Face, eye, and AF tracking are robust, though notably it lacks animal eye AF found in newer models. Real-time autofocus tracking excels, especially for moving subjects in wildlife or sports contexts. It also offers touch-activated focus for intuitive control.

The TX1, by contrast, relies on a primitive contrast detection system with only 9 focus points and no face or eye detection. This makes subject acquisition slower and less reliable, which might frustrate moving subject usage.

In practical terms, the RX100 VI is a sniper’s tool where autofocus performance counts, while the TX1 suits leisure shooters taking mostly static scenes.

Burst Shooting and Buffer: Freeze the Moment

Burst speed and buffer depth are often overlooked but critical for wildlife and sports photography.

Remarkably, the RX100 VI can shoot up to 24 frames per second (fps) with autofocus tracking - a professional-grade feature in a compact body. Buffer depth allows dozens of continuous JPEGs before slowdown, ideal for capturing peak action moments.

The TX1 does not advertise any continuous shooting mode and max shutter speed caps at 1/1250s - insufficient to freeze the fastest action cleanly.

If your work involves chasing movement, the RX100 VI is hands down the more capable tool.

Video Capabilities: 4K Video with Transportable Power

Video is an increasingly crucial feature in hybrid cameras.

The RX100 VI supports Ultra HD 4K (3840 × 2160) video at 30p using high bitrate XAVC S codec with clean H.264 compression. It offers S-Log shooting, image stabilization during video capture, and precise manual control of exposure - all fantastic for vloggers and filmmakers desiring compact gear.

The TX1 tops out at HD 720p video at 30fps - underwhelming by modern standards and without advanced codecs or stabilization.

While neither camera has microphone or headphone ports, the RX100 VI’s video prowess makes it a portable video powerhouse. The TX1 is mainly for casual video captures.

Battery Life and Storage: Practical Considerations for Real Shooting Days

Battery life affects how a camera fits into your workflow.

The RX100 VI uses Sony's NP-BX1 battery with a rated 240 shots per charge - not stellar but typical for large sensor compacts. It supports USB charging for convenience on travel, which I value highly. It records to SD/SDHC/SDXC cards and Memory Stick Duo variants on one slot.

The TX1’s battery specs are less documented, but expected to offer shorter shooting sessions due to older tech and small design. It uses Memory Stick Duo and internal storage options but lacks support for SDXC cards.

In busy shoots, the RX100 VI demands spare batteries or USB power banks. The TX1, being simpler, relies on daily charges.

Connectivity: Wireless Convenience vs Legacy

Connectivity options have evolved in leaps and bounds.

The RX100 VI includes WiFi, Bluetooth, and NFC for quick image transfer and remote control from smartphones. HDMI output facilitates tethered shooting or external monitoring.

The TX1 predates these standards and offers no wireless features; USB 2.0 and HDMI are its limited interfaces.

For modern workflows requiring fast sharing or control, the RX100 VI aligns better.

Durability and Build: Weather Resistance and Materials

Neither the RX100 VI nor the TX1 offer weather sealing, dustproofing, or shock/freezeproof features. Both target urban and travel photographers who exercise caution accordingly.

The RX100 VI's build quality feels more robust and professional, with metal construction and tight tolerances, compared to the plastic-bodied TX1.

Price to Performance: Is the Premium Worth It?

Pricing reflects their eras: the RX100 VI lists at approximately $1198 new, while the TX1, a decade old, is roughly $350 used.

For the extra cost, the RX100 VI delivers leaps in sensor tech, lens versatility, autofocus, video, and handling. However, some may find the TX1 attractive for its simplicity and ultra-compact size if on a tight budget or desiring a lightweight beater camera.
