When Sony launched the RX100 III in 2014, it set a new standard for large-sensor compact cameras, captivating enthusiasts hungry for quality in a pocketable form. On the other hand, the TX200V, released two years earlier, aimed at ultra-compact convenience with its slim profile and versatile zoom. Having tested both extensively in real-world scenarios - from high-contrast mountain landscapes to fast-paced street festivals - I’m excited to share a detailed comparison that goes beyond specs, diving into how each camera performs where it truly matters.

Whether you’re after stellar image quality for portraits, a rugged travel companion, or a discreet street shooter, this article will help you decide which Sony suits your style and budget best.

Getting Hands-On: Size, Build, and Ergonomics

First impressions count, and handling a camera often makes or breaks the shooting experience. The RX100 III and TX200V are from different philosophy camps: the RX100 III is a large sensor compact, whereas the TX200V is an ultra-compact camera designed for pure portability.

RX100 III: Feels solid and confident in hand. Its body dimensions are 102 x 58 x 41 mm with a 290 g weight. The grip is subtle but effective. The design strikes a balance between pocketability and a robust feel. Its engineered magnesium alloy chassis offers a reassuring weight that keeps it steady during shooting without being cumbersome. The tilting screen adds versatility for shooting at various angles.

TX200V: At 96 x 58 x 16 mm and just 129 g, this camera is slim enough to slip inside a shirt pocket easily. It’s impressively light, but that slimness comes at some ergonomic expense, especially for those with larger hands. Buttons are small but thoughtfully placed. The fixed, non-tilting screen restricts compositional flexibility.

In practice, the RX100 III feels like a serious tool in a compact body - perfect for photographers who want manual control along with portability. The TX200V shines when minimalism is the priority: perfect for spontaneous snaps on the go.

User Interface and Controls: Navigating Your Creative Workflow

Both cameras reflect Sony’s design language but cater to different users.

RX100 III: Offers a traditional DSLR-style control layout - dedicated dials for aperture, shutter speed, exposure compensation; a customizable control ring on the lens; and a responsive multi-selector. This complexity means a learning curve for newbies, but for enthusiasts and pros, the tactile controls enable quick setting adjustments without delving into menus. I found the lack of touchscreen a minor inconvenience, but the 3-inch 1229k-dot tilting LCD screen and electronic viewfinder (EVF) with 1440k-dot resolution provide immersive framing in bright daylight.

TX200V: Features a simpler, touchscreen-based interface designed for ease of use. The 3.3-inch OLED display is bright and sharp, providing excellent visibility even under strong sunlight. The absence of a viewfinder means relying entirely on the screen, which I found limiting in bright conditions but acceptable for casual shooting. Manual exposure modes aren’t supported, which puts constraints on creative control.

For those who crave direct manual control, the RX100 III’s interface beats the TX200V hands down. But if you prefer touchscreen simplicity for everyday snapshots, the TX200V is intuitive and user-friendly.

Sensor Technology and Image Quality: The Core Difference

When it comes to image quality, sensor size and technology are paramount.

• Sony RX100 III: Houses a 1-inch BSI-CMOS sensor measuring 13.2 x 8.8 mm, with 20 megapixels resolution. The Bionz X processor handles noise reduction and image rendering efficiently. The camera boasts an impressive DxOmark overall score of 67, with excellent dynamic range (12.3 EV), color depth (22.4 bits), and low-light ISO performance (ISO 495).

• Sony TX200V: Sports a smaller 1/2.3-inch BSI-CMOS sensor measuring 6.17 x 4.55 mm, with 18 MP resolution. It lacks RAW support, constraining editing flexibility. Detailed DxOmark metrics are unavailable due to lack of testing, but smaller sensor size translates to lower image quality potential - especially under challenging lighting.

Real-world impact: The RX100 III delivers significantly cleaner images with richer colors and finer detail. In low-light portraits in dim cafés or dimly lit events, the RX100 III’s sensor excels at maintaining a natural skin tone and reducing noise. For landscapes, the RX100 III captures wider dynamic range, preserving shadow and highlight details better than the TX200V.

The TX200V tends to produce more noise at higher ISOs and less vibrant colors overall, but its larger zoom range compensates for composition flexibility when image quality is not paramount.

Lens and Optical Performance

The lens is your creative brush, so let’s compare:

• RX100 III: 24-70mm equivalent, fast aperture F1.8-2.8
• TX200V: 28-140mm equivalent, slower aperture F3.5-4.8

In real use, the RX100 III’s bright lens stands out sharply for portrait photography, allowing beautiful background blur and separation even indoors.

For example, I photographed subjects at a nearby café with both cameras. The RX100 III’s wide aperture delivered creamy bokeh and excellent sharpness on the subject’s eyes - critical for compelling portraits. The TX200V struggled at wider apertures and produced less natural background separation.

However, the TX200V's longer 140mm reach proved useful for distant details on walks, wildlife glimpses, and candid street shots, where zoom flexibility trumped aperture speed.

Autofocus and Speed

Both cameras advertise continuous shooting at 10 fps, but their autofocus systems couldn’t be more different.

• RX100 III: Contrast-detection AF with 25 focus points, supports face detection and tracking, and continuous AF modes.
• TX200V: 9 AF points, no continuous AF, simpler contrast detection.

Testing autofocus speed and reliability at a city street photography event yielded these findings:

The RX100 III tracked moving subjects fluidly, maintaining focus even when the action was unpredictable. Eye detection worked surprisingly well in natural light, a treat for portraits.

The TX200V struggled in low contrast and lower light, with occasional focus hunting and slower lock-on times.

In burst mode, the RX100 III’s buffer allowed sustained shooting, useful for sports or wildlife. The TX200V rapidly emptied the buffer, limiting burst length.

Video Capabilities

While neither is a video powerhouse by today’s standards, both offer full HD recording.

• RX100 III: Full HD up to 60p, AVCHD and XAVC S codecs, variable frame rates including slow motion up to 120fps (in HD). Stabilization works well in video mode, minimizing handheld shake.
• TX200V: Full HD 1080p at 60fps, AVCHD/MPEG-4, with optical stabilization. No advanced video features or slow-motion modes.

Since the RX100 III includes microphone input for external audio, it becomes a viable hybrid tool for vloggers or casual filmmakers, despite missing headphone jack or 4K recording.

Display and Viewfinder: Framing in Every Light

The RX100 III’s tilting LCD synergizes beautifully with its electronic viewfinder, facilitating creative angles - particularly helpful for macro or low-level street shots. The illuminated EVF with 100% coverage supports stability when ambient light is too harsh for LCD use.

The TX200V’s gorgeous OLED screen is the star here, with deep blacks and clean color rendition. However, lack of any viewfinder means the camera loses compositional accuracy in bright daylight, forcing you to shield the screen.

Battery Life and Storage: No Surprises but Important Considerations

The RX100 III houses a NP-BX1 battery providing approximately 320 shots per charge. Realistically, with heavy use of EVF and burst shooting, expect around 250 frames, ample for a day-long outing.

The TX200V’s NP-BN battery is rated for around 220 shots, slightly less but reasonable given the smaller size and simpler internals.

Both cameras rely on a single SD card slot. While the TX200V supports Sony’s Memory Stick Duo formats, SD compatibility generally grants better flexibility and cost-effectiveness with memory cards.

Wireless Connectivity and Extras

Wireless is a big convenience in 2024.

• RX100 III sports built-in Wi-Fi with NFC functionality. This allows remote control and quick image transfers to a smartphone or tablet.
• TX200V lacks wireless or Bluetooth capabilities, limiting your connectivity options.

Geotagging is only available on TX200V with its built-in GPS, an uncommon inclusion that benefits landscape and travel photographers who want location data embedded without an external device.

Durability and Environmental Sealing

Neither camera is ruggedized, but the TX200V features some weather sealing, offering limited resistance to dust and moisture.

This may sway buyers planning outdoor travel or casual hiking.
