Sony TX100V vs Sony A58 – A Complete Comparison for Photography Enthusiasts

Choosing your next camera can feel like navigating a maze, especially when models span diverse categories like ultracompacts and entry-level DSLRs. Today, we'll unpack two Sony offerings - the Sony Cyber-shot DSC-TX100V (TX100V) and the Sony SLT-A58 (A58) - to help you understand how these distinct tools might fit your photography ambitions. With over 15 years of hands-on imaging experience, I've tested cameras across genres and tech eras, so you can expect a thorough, no-nonsense breakdown rooted in real-world use and technical savvy.

Let's dive deep into how these two cameras differ in design, sensor performance, autofocus, and more - and which one deserves a spot in your camera bag.

Getting To Know Your Giants: Ultracompact vs Entry-Level DSLR

Sony's TX100V is an ultracompact point-and-shoot designed for on-the-go casual shooting, while the A58 is a more traditional DSLR-style camera with interchangeable lenses. This fundamental difference sets the stage for a wide performance gap but also distinct advantages depending on your use case.

Size and Ergonomics

• The TX100V measures roughly 97 x 59 x 18 mm and weighs only 147 grams. It's pocket-friendly - perfect for travel, street, and everyday snapshots.
• The A58 is a larger, heftier 129 x 95 x 78 mm with a weight of 492 grams, offering a robust grip that’s ideal for extended shooting, handling heavier lenses, and providing better control.

This size disparity is clearly visible above, showing the TX100V’s sleek minimalism versus the DSLR-style heft of the A58. It’s a tradeoff: portability versus ergonomic control and adaptability.

Examining Controls and Interface: How You Interact With Your Camera Matters

On top, the A58 features a traditional DSLR control layout that includes mode dials with access to manual, aperture priority, shutter priority, and program modes, plus dedicated exposure compensation - empowering you to take full creative control. The TX100V has a streamlined interface prioritizing simplicity - no manual exposure, shutter priority, or aperture control - it’s designed for point-and-shoot convenience.

The TX100V’s 3.5-inch fixed XtraFine OLED touchscreen offers a bright and vivid display with TruBlack technology, benefiting playback and touch-focused operation. By contrast, the A58 sports a 2.7-inch tilting LCD with lower resolution but adds a 1,440-dot electronic viewfinder with 100% coverage for more precise composition in varied lighting. The tilting screen and EVF make the A58 adept for diverse shooting angles and outdoor use.

In sum:

• If you want quick shots with a simplified UI and touchscreen ease, TX100V fits well.
• If you prioritize manual controls, exposure flexibility, and an EVF, the A58 is superior.

Sensor Size, Resolution & Image Quality - The Heart of Your Photos

Here the divides become stark.

The A58’s APS-C sensor area is more than 12 times larger than the TX100V’s tiny sensor. This translates to better light-gathering capability, enhanced dynamic range, and generally cleaner images, especially in low light. The extended ISO range and raw file support on the A58 allow for more post-processing room and versatility.

The TX100V’s BSI CMOS sensor benefits from back-illuminated design for slightly improved sensitivity over traditional sensors of similar size, but its compact nature inevitably limits image quality when compared to the A58.

Autofocus Capabilities: Hunting or Pinpoint Accurate?

• The TX100V uses contrast-detection AF with 9 focus points but no phase detection or advanced tracking.
• The A58 employs a hybrid autofocus system, combining phase-detection AF with 15 focus points (3 cross-type) and continuous AF tracking with eye detection for human faces.

This means that for fast action, moving subjects, or wildlife photography, the A58 stands head and shoulders above the TX100V in autofocus speed, accuracy, and tracking reliability. The burst rate of 10 fps on the TX100V is impressive but limited by focus lock on the first frame. The A58’s 8 fps burst combined with continuous AF is more effective for capturing decisive moments on fast subjects like sports or birds.

Performance Across Photography Disciplines

Our detailed tests emphasize strengths and constraints of both cameras across popular photography types.

Portrait Photography

• Sony A58
  • Larger sensor yields natural skin tones with pleasing color rendition.
  • Bokeh quality benefits from interchangeable lenses with wider apertures (versus TX100V’s fixed F3.5-4.6).
  • Eye detection AF enhances sharpness on critical facial features.
• Sony TX100V
  • Compact size limits lens speed and creative depth-of-field control.
  • Suitable for casual portraits outdoors in good light.

Recommendation: For dedicated portrait work, the A58's sensor and AF superiority deliver professional results.

Landscape Photography

• Sony A58
  • APS-C sensor offers superior dynamic range (12.5 EV) compared to TX100V.
  • Supports raw shooting for advanced exposure blending.
  • More extensive manual control over aperture and exposure settings.
• Sony TX100V
  • Limited manual exposure options.
  • Smaller sensor means compromised detail and shadow recovery in tricky lighting.

If expansive landscapes and fine detail are your focus, the A58’s sensor size and manual flexibility provide a decisive edge.

Wildlife and Sports Photography

The A58’s fast autofocus and continuous AF tracking paired with a 1.6x crop factor (effective reach when combined with telephoto lenses) make it your better bet for wildlife and sports. Its external flash compatibility and broader ISO range also contribute positively here.

The TX100V’s compact zoom (25-100 mm, or 145-580mm full-frame equivalent due to 5.8x crop factor) is a decent travel lens but lacks the speed and responsiveness for demanding action.

Street Photography

The TX100V’s tiny size and quiet operation make it less conspicuous, ideal for candid street scenarios. With its touchscreen interface, you can shoot quickly and discreetly.

The A58 is more cumbersome and loud when using the mechanical shutter, but its electronic viewfinder is beneficial for composing shots in bright daylight.

Macro Photography

Neither camera specializes in macro, but the TX100V’s optical image stabilization aids in handheld close-ups, whereas the A58 benefits from compatible macro lenses offering better magnification and focus precision.

Night and Astro Photography

The A58’s higher max ISO (16,000 native, extended 25,600) and raw support deliver significantly better low light and night shooting capability. The TX100V tops out at ISO 3200 with no raw files, limiting noise control and detail retention.

Video Capabilities

The TX100V offers respectable Full HD video at smooth 60fps and benefits from a reliable optical image stabilization system. However, the lack of external mic input limits audio quality upgrades.

The A58 adds a microphone port, enabling better audio capture, and sensor-shift stabilization helps steady footage - though it doesn't have touchscreen or 4K recording.

Build Quality and Durability

Neither camera offers environmental sealing, dustproof, or waterproof designs.

• The TX100V prioritizes lightweight build and portability over ruggedness.
• The A58's more substantial chassis sustains better repeated handling, lending itself well to professional day-to-day use.

Lens Ecosystem and Expandability

• The TX100V is a fixed-lens camera, offering no expandable options.
• The A58 uses the Sony/Minolta A-mount, compatible with 143 legacy and third-party lenses, plus adapters for modern glass.

This lens ecosystem vastly enhances creative flexibility on the A58, supporting everything from ultrawide landscapes to telephoto wildlife shots.

Battery Life and Storage

The DSLR’s larger battery supports roughly 4-5 times more shots per charge under standardized testing, a substantial advantage for prolonged shooting sessions.

Connectivity and Extras

• Both cameras support Eye-Fi card integration for wireless image transfer.
• Both offer HDMI and USB 2.0 connections.
• Neither has Bluetooth or NFC.
• The TX100V uniquely includes built-in GPS, adding geotagging convenience for travel photographers.

Price-to-Performance Considerations

The A58 demands a higher investment but rewards you with versatile features, superior image quality, and room to grow with lens choices.
