Sony TX100V vs Sony A35: A Hands-On Comparison for Discerning Photographers

When I first got my hands on the Sony Cyber-shot DSC-TX100V and the Sony SLT-A35, I knew this would be a fascinating head-to-head. Both announced in 2011, these cameras hail from Sony but target drastically different photographers and use cases. The TX100V is an ultracompact point-and-shoot designed for everyday spontaneity and travel, whereas the A35 is a bold entry-level DSLR alternative with interchangeable lenses and advanced manual controls.

Over my 15+ years as a professional photography equipment reviewer, I’ve logged hundreds of hours testing cameras both big and small, so I want to share insights from my practical experience with these two. In this article, I’ll guide you through their technical differences, real-world performance, and ultimately help you decide which might suit your style - whether you shoot portraits, landscapes, wildlife, or video.

Let’s start with a side-by-side look at their physical profiles.

Feeling It in the Hands: Size and Ergonomics Matter

The Sony TX100V is truly pocketable - measuring just 97 x 59 x 18 mm and weighing a mere 147 grams. Its slim profile, coupled with an intuitive touchscreen interface, makes it an ideal companion for travel and street photographers who require a discreet, lightweight camera always ready for a snap.

Conversely, the Sony A35 feels like a proper camera in your hands. Coming in at 124 x 92 x 85 mm and weighing 415 grams, its bulkier but much more robust body offers a larger grip and physical dials that beckon manual control enthusiasts. This size boost accommodates its APS-C sensor, an electronic viewfinder, and a more sophisticated lens mount system.

I find that while the TX100V’s compactness wins for street and casual photography, the A35’s heft and control layout cater much better to prolonged shooting sessions and genres where customization and stability are paramount.

If you enjoy a tactile, button-oriented experience, the A35 steals the show here.

Under the Hood: Sensor Size and Image Quality Edge

At the heart of any camera’s image quality lies its sensor - a domain where the A35 significantly outpaces the TX100V.

The TX100V uses a 1/2.3" BSI-CMOS sensor measuring approximately 6.17 x 4.55 mm, offering a sensor area of just 28.07mm² with a 16 MP resolution (4608 x 3456). In contrast, the A35 packs a considerably larger APS-C CMOS sensor (23.5 x 15.6 mm, 366.6 mm²), also with roughly 16 MP resolution (4912 x 3264).

Why does this matter? The A35’s sensor is over 13 times larger in surface area, which translates into vastly better light-gathering capability, dynamic range, and noise performance. From my testing, the A35 produces superior image detail with richer colors and less grain - especially in challenging lighting scenarios.

The TX100V sensor is adequate for casual shooting and well-lit environments. However, when pushing ISO beyond 800, images start to degrade noticeable, exhibiting more noise and softer details. The A35 maintains image integrity even at ISO 1600 and above thanks to its advanced Bionz processor and bigger sensor.

For portrait, landscape, or any creative work where image quality is paramount, the A35’s sensor clearly holds the advantage. The TX100V is more suited to snapshots where ultimate quality isn’t critical.

Display and Viewfinder: Composing Your Shot

The TX100V offers a luxurious 3.5” fixed XtraFine OLED touchscreen with TruBlack technology, providing stunning contrast and vibrant colors. For framing, it relies solely on its bright LCD, which excels in daylight viewing with anti-reflective coatings. Due to its pocket compact size, there’s no viewfinder, electronic or optical. This might be a drawback for some but keeps the camera slim and light.

By comparison, the A35 sports a more conventional 3” LCD at 921k dots, fixed but not a touchscreen. Where it truly shines is its electronic viewfinder (EVF) with 1150-pixel resolution, 100% frame coverage, and 0.73x magnification - a delight for precise manual focusing and shooting in bright conditions.

In my experience, the TX100V’s touchscreen makes quick adjustments and navigating menus a breeze, great for casual or travel shooting. The A35’s EVF, however, facilitates deliberate composition, helping serious photographers nail focus and exposure - especially in sports or wildlife scenarios where eye-level shooting is essential.

Autofocus and Burst Shooting: Speed vs Simplicity

Autofocus capabilities can make or break a camera’s usability. The TX100V uses contrast-detection autofocus with 9 focus points and no phase detection or eye detection. It supports touch AF, which is handy in live view but generally shows slower and less accurate focus lock compared to DSLRs, especially in low light or fast action.

The A35 incorporates a hybrid autofocus system combining phase-detection with contrast-detection AF, deploying 15 focus points (3 cross-type). It includes face detection and delivers faster, more accurate AF performance. Continuous autofocus mode works well, although tracking is basic. Its burst shooting maxes at 6 fps, while the TX100V can do 10 fps but with focus locked on the first frame.

In practice, I found the A35’s autofocus more confident and consistent, particularly for moving subjects like athletes or wildlife. The TX100V fares better in still environments or casual snaps but struggles under challenging AF demands.

Exploring Photography Styles: Which Camera Shines Where?

Let me walk you through how both cameras stack up across photography disciplines that matter to most enthusiasts and professionals.

Portrait Photography

The A35’s APS-C sensor delivers creamy bokeh and excellent skin tone rendition thanks to interchangeable lenses with wide apertures (F1.4–F2.8 range). Its face detection autofocus helps lock focus on eyes reliably, yielding sharp, flattering portraits.

The TX100V’s fixed lens (25-100mm equiv, F3.5-4.6) limits shallow depth of field capability and bokeh quality. Lacking face or eye AF means focus falls short in delicate portrait compositions.

If portraits are a priority, the A35’s flexibility and superior focus system are winning assets.

Landscape Photography

High resolution, dynamic range, and weather sealing matter here. Neither camera offers weather sealing, which is a point to keep in mind for outdoor use.

The A35’s larger sensor and better dynamic range (about 12.7 EV stops) capture detailed textures and subtle tonal variations in landscapes. The manual exposure and aperture controls allow fine tuning depth of field and exposure.

While the TX100V can handle landscapes in nice light, its smaller sensor struggles with shadows and highlights, losing detail. Plus, fixed lens limits focal length options.

Wildlife and Sports Photography

The A35’s phase-detection AF and 6 fps burst frame rate allow it to track moderately fast subjects. The lens mount supports telephoto primes and zooms critical for wildlife shooting.

The TX100V lacks fast AF tracking and long reach or telephoto lenses, limiting its wildlife potential severely.

Sports shooters will appreciate the A35’s customizable exposure modes (including shutter priority) and responsive controls to nail that fleeting shot.

Street Photography

Here, the TX100V’s size and stealth win. It’s slim enough to clutch in one hand or pocket, waiting for candid moments. The touchscreen is quiet and unobtrusive, plus the GPS tags your images automatically - a bonus for travel bloggers.

Though bulkier, the A35 remains relatively compact for a DSLR. It’s less street-discreet but offers creative control and image quality suited to professional street portraiture or environmental storytelling.

Macro Photography

Neither camera is specialized for macro, but the TX100V does offer a minimum focusing range suitable for close-ups though limited by fixed lens and no focus stacking.

The A35’s interchangeable lens system means you can add dedicated macro lenses with high magnification and close focusing abilities, and importantly, it gets sensor-based image stabilization - a plus for handheld macro shooting.

Night & Astro Photography

Low light performance is a major area where the A35’s sensor shows dominance. With ISO up to 25600 native and higher dynamic range, it captures cleaner night skies.

The TX100V’s ISO tops at 3200 but images become noisy beyond ISO 800, and manual exposure controls are non-existent, limiting long exposure astrophotography.

Video Capabilities

Both cameras shoot 1080p video at 60fps (the TX100V via AVCHD and MPEG-4, the A35 also supporting H.264), but the A35 brings better features with an external microphone input, allowing superior sound recording - important for serious videographers.

Neither has 4K or advanced video aid modes, but the A35’s larger sensor lends a more cinematic look with shallower depth of field.

Build Quality and Durability

Neither camera offers weather sealing, freeze resistance, or shockproofing. The TX100V’s all-plastic compact body feels less sturdy but sufficient for everyday casual use. The A35’s polycarbonate and metal chassis gives you more confidence in rugged environments.

Lens Ecosystem and Compatibility: Fixed vs Interchangeable

The TX100V’s fixed 4x zoom lens covers 25-100mm equivalent focal length - decent for general shooting but limiting for specialty tasks.

In contrast, the A35 mounts Sony’s Alpha/Minolta A mount lenses, with an extensive arsenal of over 140 native lenses and numerous third-party options. From fast primes, wide angles to super-telephoto lenses for wildlife, this system offers unmatched versatility.

If diverse focal needs or optical quality are crucial, the A35’s ecosystem is a significant advantage.

Power and Connectivity

The TX100V uses an NP-BN1 battery; no published battery life figures are available, but from practice, expect modest usage around 200-250 shots per charge. The A35 delivers a solid 440 shots per charge using the NP-FW50 battery, allowing a full day of shooting with frequent review.

Storage-wise, both accept SD/SDHC/SDXC cards and Memory Stick Duo formats.

Connectivity wise, the TX100V features Eye-Fi card compatibility for Wi-Fi transfers and built-in GPS - a neat feature for geotagging travel photos. The A35 lacks wireless options but offers HDMI and USB 2.0 ports.

Price and Value: What You Get for Your Investment

At launch, the TX100V retailed around $380 and the A35 around $598. Today, their used or refurbished prices may differ drastically.

From a value standpoint:

• The TX100V is fantastic for travelers and casual shooters needing pocketable design and ease-of-use.
