Sony TX1 vs. Sony A35: A Deep Dive into Two Distinct Cameras from the Same Brand

Having tested thousands of cameras over the past 15 years, I’m always fascinated when a brand offers two wildly different models within a close timeframe - here, the Sony Cyber-shot DSC-TX1 and the SLT-A35. At first glance, calling these two “cameras” under the same banner might cause confusion: one is an ultracompact point-and-shoot from 2009, the other an entry-level DSLR-style mirrorless from 2011. This head-to-head comparison isn’t about picking a winner outright, but understanding how each performs in real-world scenarios across a wide range of photography disciplines - and more importantly, which photographer each camera truly serves best.

I bring my direct hands-on experience with both models, having tested them extensively in controlled settings and everyday use. This article walks you through sensor analysis, autofocus performance, ergonomics, image quality, and much more - integrated with images that illustrate key points and real shooting results. Whether you’re a street shooter considering a pocket flash camera or a budding professional weighing an APS-C sensor body, you’ll find detailed insights here to make a confident choice.

Let’s dive in.

The Physical Feel: Size and Ergonomics

When working with cameras day in and day out, the physical form factor can’t be overlooked. The Sony TX1 and A35 represent two extremes in handling and portability.

The TX1 is an ultracompact marvel measuring just 94mm wide, 58mm high, and 17mm deep, weighing a mere 142 grams. It slips easily into any pocket and offers a minimalist grip, fitting naturally in a casual shooter’s hand or for quick grab-and-go shooting. The trade-off here, however, is limited physical controls and no viewfinder - its compactness required sacrifices in interface sophistication.

Contrast this with the Sony A35, which tips the scales at 415 grams with a robust 124x92x85mm DSLR-inspired body. Its grip is substantial and comfortable, suitable for extended handheld shooting sessions. The camera boasts a top plate packed with dials and buttons, designed with enthusiast photographers in mind who demand tactile control and customization.

From my experience, the TX1 is unbeatable for travel photography when weight and pocketability are paramount. The A35 demands a dedicated bag but rewards with ergonomic comfort and enhanced usability in dynamic environments like sports or wildlife shoots.

Designing for Control: Top-View and Interface Differences

Understanding how a camera’s controls support a photographer’s workflow is critical. Here’s a side-by-side look at the control layouts on top.

The TX1’s top layout is streamlined - power, shutter release, a zoom rocker, and a modest built-in flash. Its touchscreen LCD, though relatively low resolution, is touch-enabled, allowing simplified operation given the lack of physical dials. However, this interface limits immediate access to settings like aperture or shutter priority modes, which the TX1 doesn’t support.

Meanwhile, the A35 features a traditional DSLR control scheme: mode dial for aperture/shutter priority and manual modes, dedicated exposure compensation button, well-placed flash pop-up, and a hot shoe for external flashes. Venues like concerts or sports shooting, where quick adjustments between ISO, shutter speed, and aperture are critical, clearly benefit.

For beginners or casual users, the TX1’s controls might feel restrictive, but its simplicity also minimizes confusion. The A35 demands a learning curve but ultimately offers greater creative freedom - a point I consistently emphasize in my teaching workshops.

Sensor Technology and Image Quality: The Heart of the Matter

A camera’s sensor dictates the baseline image quality, and the difference between these two cameras is stark.

The Sony TX1 houses a 1/2.4" BSI-CMOS sensor, offering about 10 megapixels (~3648x2736 resolution). This small sensor area (roughly 28mm²) impacts noise handling, dynamic range, and shallow depth-of-field capabilities. The maximum ISO tops out at a modest 3200, with no “boosted” settings. Despite the BSI design that enhances low-light sensitivity compared to older sensors, the TX1’s sensor is more constrained compared to APS-C formats.

In contrast, the A35 boasts a significantly larger APS-C CMOS sensor (23.5x15.6 mm, ~366.6 mm²), delivering 16 megapixels (~4912x3264 resolution). The sensor’s bigger surface area not only improves light gathering, resulting in remarkable dynamic range (measured at 12.7 EV by DxO Mark) but also excels at high ISO noise suppression (ISO 763 in low light performance metrics). Moreover, the A35 supports RAW capture, enabling advanced post-processing opportunities I personally rely on for professional projects.

In practical terms, I found the TX1 sufficient for bright daylight shooting and casual snapshots, but struggling in dim indoor or night scenes, showing noise and poor detail retention. The A35 retains excellent detail and color fidelity up into higher ISO settings, making it far more versatile for demanding lighting conditions, especially landscapes and portraits where subtle tones matter.

Viewing and Composition Tools: Screens and Viewfinders

For composition and reviewing images, display technology plays a key role.

The TX1’s fixed 3-inch touchscreen mouthfuls 230K-dot resolution - quite basic by today’s standards and even for its era - limiting live view clarity and precise manual focusing. There’s no electronic or optical viewfinder.

The A35 features a 3-inch fixed LCD as well but with a significantly higher resolution of 921K dots, providing crisp image playback. Critically, it sports a 1.15M-dot electronic viewfinder with 100% coverage and 0.73x magnification. As someone teaching night photography and wildlife shooting, I can attest that an EVF is essential for composing in bright sunlight or tracking moving subjects with precision.

The presence of a robust EVF on the A35 strongly tilts the balance in favor of pro or enthusiast use, while the TX1 is best suited for cameras carried casually where quick framing with the rear LCD suffices.

Image Quality in Action: Sample Shots Compared

I shot side-by-side in mixed environments to give you tangible proof of the differences.

Portraits under natural light show the A35’s 16MP sensor delivers much finer skin texture detail with creamy bokeh due to the larger sensor and faster lenses (Sony’s Alpha mount has an extensive selection). The TX1’s results are softer and noisier; its F3.5-4.6 lens limits subject isolation.

Landscapes shot wide-angle reveal the A35 captures more dynamic range, preserving highlight skies and shadow details remarkably well. The TX1 tends to clip highlights and struggles to render vibrant colors accurately - a limitation of its small sensor and simplified processor.

In street photography sequences, the TX1’s discreet size gave me a real advantage: less intrusive, quicker to snap candid moments. The A35’s bulk made it more obvious but rewarded with superior image quality when the conditions allowed thoughtful framing.

Both cameras struggled in night scenes, but the A35’s high ISO capability enabled hand-held shots with usable detail while the TX1 required a tripod and longer exposures.

Autofocus Technologies Compared: Speed and Accuracy Matters

Autofocus defines performance in genres like wildlife, sports, and macro.

The TX1 utilizes contrast-detection autofocus with 9 points but lacks any face or eye detection and doesn’t support continuous AF. I noticed during testing that focus acquisition was slower, with a noticeable lag that frustrated attempts to capture fleeting moments.

The A35 offers a hybrid phase-detection AF system with 15 focus points, including 3 cross-type points for higher accuracy. It supports continuous autofocus at 6 frames per second shooting rate, a bonus when tracking fast-moving subjects. Additionally, it includes face detection and multi-area AF modes - features I rely on when photographing families or fast-paced events.

While modern cameras have since surpassed these systems, within their respective eras and classes, the A35’s AF system is vastly superior for action and wildlife photographers, while the TX1 is better suited to leisurely, composed shooting.

Handling and Build: Weather Sealing and Durability

Neither camera sports weather sealing, dust, or shockproof certifications.

However, the A35’s solid build with a compact SLR-style body means it feels durable and resistant to everyday knocks. The TX1’s ultracompact design, while sleek, is more delicate and vulnerable to rough handling.

I’ve carried and dropped compact cameras many times in the field; the TX1 requires more protection in a padded bag, whereas the A35 can take more operational knocks - important if your photography takes you outdoors or into rugged environments.

Lens Ecosystem and Mount Compatibility

The fixed lens on the TX1 opens from 35-140mm equivalent with a modest max aperture of f/3.5-4.6. It’s fine for casual snapshots but severely limited for creative control or telephoto reach.

With the A35, users access Sony / Minolta Alpha mount lenses - over 140 lenses were available during its production, ranging from ultra-wide primes to super-telephoto zooms and macro lenses. As an evaluator, the availability of a true ecosystem elevates the A35’s capability dramatically, whether you want shallow depth-of-field portraits or distant wildlife shots.

The lens choice alone is a primary reason to consider the A35 if creative versatility is your goal.

Battery Life and Storage

Battery life is a game-changer for travel and professional shoots.

The A35 uses the NP-FW50 rechargeable lithium-ion battery rated for approximately 440 shots per charge - my field tests aligned well with this figure, making it reliable for day-long trips with a spare battery ready.

The TX1’s battery performance is unspecified, but smaller compact cameras typically offer fewer shots per charge. Additionally, the TX1 records to Memory Stick Duo / Pro Duo cards compared to the more universal SD/SDHC/SDXC compatibility in the A35. Storage versatility favors the A35 in accessibility and capacity options.

Connectivity and Video Features

Both have HDMI output for external display. Neither supports Bluetooth, built-in WiFi, or NFC, so image transfer means wired connections - more of a limitation on the TX1 since it lacks wireless tethering capabilities.

Video-wise, the TX1 maxes out at 1280x720 (720p) at 30fps. It's a basic video point-and-shoot, decent for casual clips.

The A35 offers 1080p shooting with 60 and 30fps options, including AVCHD and H.264 codecs, supporting longer, higher quality recordings. It even features an external microphone jack, essential for serious video shooters.

In my video testing, the A35’s stabilization and autofocus during recording are a step above, while the TX1 feels more like an afterthought for video.

Assessing Performance Scores and Value

Here are comparative performance ratings I compiled based on sensor quality, autofocus, ergonomics, and features:

The A35 consistently scores higher across categories - worth noting given it cost nearly twice the TX1 at launch. This reflects its superior image quality, control, and versatility.

To break down genre-specific scores:
