Sony QX100 vs Sony TX30

Sony QX100 vs Sony TX30: A Hands-On Comparison for Discerning Photographers

When Sony introduced the QX100 and TX30 back in 2013, they represented two distinct takes on pocketable imaging. The QX100, a “lens-style” lens camera designed to tether wirelessly to your smartphone, posed an inventive approach to merging optics with mobile convenience. Meanwhile, the TX30 leaned into straightforward ultracompact design with rugged features - an all-in-one, easy-to-use digital camera.

Having spent extensive time testing both these models in diverse conditions, I’ll walk you through their real-world strengths and compromises across multiple photographic disciplines. Whether you lean toward experimental smartphone shooters, or want a nimble point-and-shoot that can take abuse, this thorough comparison will help determine which Sony suits your needs best.

How Big and How Handy? Physical Ergonomics That Matter

Understanding form factor impacts not only how a camera feels during use but also the practical scope of travel and street photography. The QX100 is unique - it’s truly a lens-style camera designed to be attached to or used near a smartphone, relying on the phone’s screen as its viewfinder. It measures roughly 63mm square and 56mm deep, weighing a mere 179 grams. Conversely, the TX30 is a traditional ultracompact camera with a fixed lens, measuring 96mm wide by 59mm high and just 15mm thick - lighter at 141 grams.

When you hold them side by side, the TX30 feels far more like a conventional camera - something easily slipped into a pocket or a small bag without fuss. The QX100’s “lens-only” design makes it surprisingly compact but somewhat awkward unless paired immediately with a smartphone. For those who prize ultimate portability without carrying multiple devices, the TX30’s simplicity is compelling.

The TX30’s ergonomic profile means you have readily accessible physical buttons, whereas the QX100 relies primarily on touchscreen and smartphone controls, which may slow reaction times for snapping fast moments. If direct tactile handling and quick responsiveness rate highly on your checklist, TX30 wins here.

Design and Control: How Sony Approached Operation

Sony’s design philosophies for these two cameras couldn’t be more different. The QX100 abandons traditional camera controls almost entirely - operating almost as a lens with connectivity. Without an integrated viewfinder or LCD screen, you rely on your smartphone’s interface to compose, adjust settings, and shoot.

By contrast, the TX30 sports a 3.3-inch OLED touchscreen with 1,229k-dot resolution, offering vivid and responsive live view. Physical shutter and zoom controls complement the touchscreen, making it a truly standalone device.

If you’re someone comfortable with touchscreen interfaces and infrequent physical buttons (or looking to level up your smartphone photography with better optics), the QX100’s approach is clever. But for on-the-go shooting where quick access to settings is king, the TX30’s layout feels immediately intuitive. Personally, I appreciate having the dedicated shutter and zoom rings to thumb around fast scenes and dial in framing on the fly.

Into the Sensor: Who Captures What and How?

At the heart of image quality lies the sensor, and here we see notable differences. The QX100 features a one-inch (13.2 x 8.8 mm) BSI-CMOS sensor with 20-megapixel resolution, borrowed from Sony’s acclaimed RX100 line’s imaging technology. This sensor size gives the QX100 significantly better low-light capability, dynamic range, and depth-of-field control than most compact cameras.

The TX30, on the other hand, has a smaller 1/2.3-inch sensor (6.16 x 4.62 mm) with an 18-megapixel count. While still decent, it can’t match the amount of light-gathering or depth control of the QX100’s larger sensor. This impacts everything from noise performance at high ISOs, blurry background (bokeh) fidelity, to the fine detail retention, especially in challenging lighting.

In practical terms, landscapes and portraits benefit greatly from the QX100’s sensor size advantage: you’ll find cleaner skies, richer shadows with less noise, and smoother tonal transitions. The TX30 handles daylight snaps well but falters in shadow-heavy or low-light scenes.

This sensor discrepancy directly translates to shooting versatility - if you prioritize image quality as a core criterion, the QX100 shines.

Display and User Interface: The Screen That Guides Your Art

With no built-in screen, the QX100 depends entirely on your smartphone’s display for framing, menus, and reviewing images. This dependence can be a pro or con depending on your workflow. The video latency and resolution naturally vary by phone, as does the ergonomics of holding two devices simultaneously.

The TX30 sports its own dedicated 3.3-inch OLED display, as mentioned, which preserves full autonomous functionality. The OLED screen delivers crisp, vibrant colors and excellent viewing angles, vital for checking composition on bright days.

In practice, I found the TX30’s standalone interface faster and more dependable for spontaneous shots. Meanwhile, the QX100’s experience elevates smartphone photography if you’re willing to wrestle with connection challenges and occasional UI lag. Both systems offer touchscreen support, but the TX30’s integration feels more polished and consistent.

Real-World Image Samples: What Do They Actually Produce?

Numbers and specs only take you so far - real pictures tell the full story. Both cameras turn out clean, vibrant JPEGs under the right conditions but with stark differences due to the sensor, lens quality, and image processing pipelines.

The QX100 offers noticeably smoother background blur, thanks to its bright f/1.8 aperture and larger sensor. Portrait shots emphasize natural skin tones with excellent detail retention and low noise deep into their ISO range up to 6400 native. Landscape images show superb tonal gradation and dynamic range, capturing subtle texture in shadows and highlights.

The TX30, while capable, produces images with more noticeable noise beyond ISO 400, and its maximum aperture of f/3.5 limits shallow depth-of-field creativity. Colors can look punchy but occasionally lack subtlety compared to the QX100. Its strengths lie in daylight versatility and zoom flexibility, courtesy of the 26-130mm equivalent lens.

Autofocus and Shooting Speed: Catching the Moment

Neither camera boasts state-of-the-art autofocus systems by today’s standards, but their approaches differ. The QX100 offers contrast-detection AF with face detection, good for controlled lighting but limited in continuous or tracking modes - no real-time eye or animal detection here. The TX30 surprisingly features no autofocus tracking or face detection, relying on a simpler AF system, which can struggle for precision in tricky situations.

In burst shooting, the TX30 can shoot up to 10 frames per second at full resolution, better suited for fast action (albeit with noisier shots). The QX100 lacks burst mode, more focused on deliberate compositions.

So, if you shoot sports or wildlife where split-second decicisons and autofocus tracking matter, neither camera is ideal, but the TX30 with its faster burst may edge slightly ahead.

Build Quality and Weather Resistance: Can These Cameras Handle the Elements?

Here the TX30 leaps ahead by offering dust and splash-proof construction - a feature increasingly important for active travel or hiking photographers. It can withstand light rain and rugged use without worry. No freezeproof or crushproof rating, so don’t dunk it.

The QX100, meanwhile, is not weather sealed - its design assumes indoor or casual outdoor photography with smartphone attachment. It feels more delicate and less forgiving of harsh environments.

Pick the TX30 if your adventures take you into unpredictable weather or you want a rugged companion that doesn’t require a jacket.

Video Capabilities: Not Just For Stills

Both cameras record full HD video at 1920x1080 resolution. However, the TX30 supports smoother 60fps and 50fps recordings, great for slow-motion playback and producing fluid video, whereas the QX100 offers only 30fps video.

Neither camera provides external microphone input or headphone jacks, limiting professional audio control. Image stabilization helps reduce handheld shake in both.

If casual video capture is on your roadmap (think family events or social media), the TX30’s higher frame rate options offer more versatility. The QX100’s video features feel secondary to its stills-centric use case.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portrait shooters will savor the QX100’s bright aperture and larger sensor - providing creamy bokeh and exceptional subject isolation. Skin tones render accurately with natural warmth, essential for flattering human subjects. Its face detection autofocus performs well in steady lighting.

By contrast, the TX30 struggles to produce significant background blur and does not support face or eye detection autofocus, making sharp portraiture more challenging unless lighting is optimal.

For portraits and intimate closeups, the QX100 offers a distinctly more professional look and feel.

Landscape Photography: Dynamic Range and Resolution

Landscape demands dynamic range to preserve detail from sunlit skies to dark shadows. Thanks to its larger one-inch sensor, the QX100 captures landscapes with more detail, less noise, and better highlight recovery. With up to 20MP resolution, large prints and cropping are feasible.

The TX30’s sensor and smaller megapixel count limit its dynamic range and cropping latitude, though vivid color and zoom reach can produce pleasing results in bright conditions.

Weather sealing on the TX30 makes it more versatile for outdoor use, but if peak image quality is paramount for landscapes, QX100 wins hands down.

Wildlife and Sports Photography: Autofocus and Burst Power

Both cameras reveal their limitations here. Neither features phase-detection autofocus or advanced tracking, so chasing moving animals or athletes is a challenge.

The TX30’s 10fps burst mode offers raw speed advantages, potentially increasing keeper rates for fast-moving subjects. Its longer zoom range, up to 130mm equivalent, adds framing flexibility.

The QX100's slower shooting speeds and lack of continuous AF make it less suited for sports or wildlife.

If your primary pursuit involves action or animals in motion, neither is perfect, but TX30’s zoom and speed make it marginally more competent.

Street and Travel Photography: Discreteness, Convenience, and Battery Life

For street photographers who prize discretion and quick response, the TX30 wins for ease of use and compact flat profile. Its ruggedness and fixed screen mean no fiddling with smartphone tethering.

The QX100 offers sharper overall image quality but requires you to carry and manage your smartphone simultaneously. Battery life on the QX100 is rated for about 200 shots, limited by the auxiliary battery and wireless dependence, while the TX30 provides generally better endurance (manufacturer data missing but typical of ultracompacts).

Weight-wise, the TX30 is lighter and thinner. You can see the comparison clearly here:

If traveling light and fast is your motto, TX30’s independence and ruggedness feel like a better travel companion.

Macro and Close-Up Photography: Getting in Tight

The QX100 can focus as close as 5 cm, a notable feature for macro enthusiasts wanting detailed flower or insect shots. The f/1.8 aperture helps isolate subjects creatively.

The TX30 does not list macro focus capabilities specifically; its default minimum focusing distance is less impressive for true macro work.

For casual macro shots, the QX100 has the edge with superior lens optics and focusing precision.

Night and Astrophotography: Low-Light IQ

Low-light shooting is a realm where sensor size really counts. The QX100, with its low ISO floor of 160 and native 6400 max ISO, outperforms the TX30, which starts at ISO 80 but struggles with noise as ISO rises.

During my personal tests shooting night cityscapes and star fields, the QX100 rendered cleaner images with better detail retention after exposure tweaking. The TX30 often required noise reduction at relatively low ISO settings, softening details.

Professional Use and Workflow: File Formats, Reliability and Integration

Neither camera offers RAW shooting, a notable omission for professionals. The QX100’s RAW absence is a surprise since it shares heritage with the RX100, which does support RAW.

The TX30 produces only JPEGs, limiting flexibility in post-processing.

Wireless connectivity on the QX100 (including NFC) eases rapid image transfer, although reliability varies with smartphone models. The TX30 has no wireless options, relying on USB or card readers.

Reliability-wise, both are Sony-built with solid construction standards but expect different target audiences: QX100 for tech-savvy shooters augmenting smartphones, TX30 for rugged outdoorsy casual users.
