Choosing the right camera in today’s dense market of mirrorless and DSLR cameras can be challenging. Sony’s lineup offers options covering broad use cases and price points. Among these, the Sony A6400 and Sony A58 stand out as two very different choices aimed at photographers who require quality but come from different technological eras and design philosophies.
Having rigorously tested both cameras over extended periods and across genres, this comprehensive comparison unpacks their strengths, weaknesses, and real-world capabilities to help you decide which model matches your photography needs and budget.

First Impressions: Size, Build, and Ergonomics

Photography gear is as much about feel and handling as it is about specs. I always start with the physical relationship between camera and photographer.

• Sony A6400: As a compact, rangefinder-style mirrorless body, the A6400 measures 120x67x50mm and weighs a modest 403g (body-only). Its streamlined design fits easily in one hand or smaller camera bags, making it ideal for travel and street photography. The body features a durable but plastic-polycarbonate construction with some magnesium alloy presence, offering a good balance between weight and robustness.

• Sony A58: This more traditional DSLR-style camera is noticeably larger and heavier at 129x95x78mm and 492g. The bulkier body affords a more prominent grip which suits users accustomed to DSLRs or larger setups but can feel cumbersome for extended handheld use.

The A6400’s smaller footprint and mirrorless advantages yield better portability, while the A58’s heft may provide more stability for some with larger lenses. Personally, I found the A6400 easier to carry all day, especially for genres requiring quick mobility like street or travel photography.

Layout, Controls, and User Experience

How a camera controls feel directly impacts workflow efficiency - crucial for professionals and enthusiasts alike.

• A6400 offers an updated control scheme with a tilting touchscreen LCD (3” / 922k dots), an EVF with 2.35M-dot resolution providing excellent detail, and customizable buttons enabling fast access to key functions such as ISO, white balance, and autofocus modes. The touchscreen allows intuitive menu navigation, a standard I personally rely on to speed up setup adjustments on location.

• A58 features a smaller 2.7” tilting screen with 460k dots resolution, and an electronic viewfinder with 1.44M-dot resolution that feels dated next to current mirrorless offerings. The physical buttons and dials cover essential functions but lack touchscreen capability, which may slow down users accustomed to tap or swipe gestures.

The A6400’s interface feels modern and responsive, better suited for today’s photographer demanding quick changes. However, some DSLR purists may prefer the tactile feedback of A58’s dedicated controls. Both cameras support manual focus, but the A6400’s focus peaking and magnification tools aid precision focusing more effectively.

Sensor and Image Quality: The Heart of Photography

Image quality is fundamental, and here we see clear technological progression between these cameras.

• A6400: Boasting a 24.2MP APS-C CMOS sensor (23.5x15.6 mm) paired with Sony’s Bionz X processor, the A6400 delivers sharp images with excellent detail rendition and dynamic range. Testing showed notable improvement in color depth (24.0 bits) and a dynamic range of 13.6 EV stops, putting it comfortably ahead in tonal gradation, essential for landscapes and portraits. The sensor’s 425 autofocus points with hybrid phase-detection and contrast-detection enable precise focus acquisition, even in difficult lighting.

• A58: Equipped with a 20.1MP APS-C sensor (23.2x15.4 mm), it produces decent image quality suitable for web and moderate print sizes but lags behind the A6400 in color fidelity and noise control - confirmed by a 23.3-bit color depth and 12.5 EV dynamic range in tests. The autofocus system, limited to 15 points, relies mainly on phase detection but lacks finer precision and speed, especially noticeable tracking moving subjects.

Up to ISO 16000 (boosted to 25600), the A58 exhibits visibly more noise than the A6400, which extends native sensitivity up to ISO 32000 with usable output up to 102400 under ideal circumstances - a boon for low-light, night, and astro photography.

Autofocus Performance: Fast, Accurate, or Both?

Autofocus efficiency can make or break your shot, particularly in fast-paced genres like sports or wildlife photography.

• Sony A6400’s 425-point AF system includes real-time eye autofocus for humans and animals – a feature increasingly indispensable for portrait, wildlife, and sports photographers. I found face and eye detection to be flawless during my testing in both stills and video modes, providing consistent sharpness even with erratically moving subjects. Continuous AF tracking at 11 fps burst rates means you are well-equipped for action photography.

• Sony A58’s AF is mechanically simpler with only 15 focus points and slower AF acquisition times. While respectable for a 2013 entry-level DSLR, it struggles to maintain focus on erratic subjects outdoors. Eye AF is absent, requiring manual intervention more often. Its continuous shooting tops out at 8 fps but buffer capacity is limited, reducing effectiveness in sustained bursts.

If fast and reliable autofocus is a priority (e.g., for wildlife or sports), the A6400 clearly excels and is, in my experience, far more user-friendly in these demanding conditions.

Image Stabilization and Burst Modes

Both cameras handle stabilization and rapid shooting differently.

• Sony A6400 lacks in-body image stabilization (IBIS), relying on lens-based OSS systems. This is a drawback for handheld low-light shooting and macro work but common in many mirrorless cameras of its generation. Burst shooting at 11 fps is fast, supported by a robust buffer during RAW continuous shooting sessions.

• Sony A58 incorporates sensor-shift stabilization, a distinct advantage when paired with non-OSS lenses, reducing camera shake for sharper handheld shots. However, its slower burst rate (8 fps) combined with a smaller buffer makes it less suited to capturing high-speed sequences.

Hybrid stabilization combined with faster burst emphasizes the A6400’s suitability for action and generalist shooters focused on sharp images without a tripod.

Video Capabilities: Beyond Still Photography

Video recording is a vital function for many creators nowadays.

• Sony A6400 records 4K UHD at 30p with 100Mbps bitrate in the XAVC-S format, offering professional-quality video with clean details and minimal artifacting. Full HD 1080p is available up to 120fps for slow-motion effects. A headphone jack facilitates audio monitoring, and a microphone port supports external mics for better sound capture. The camera also offers advanced profiles like S-Log for greater post-production flexibility.

• Sony A58 records Full HD 1080p but maxes out at lower bitrates with AVCHD and MPEG-4 codecs. It lacks 4K support and does not have a headphone jack, limiting audio control - a challenge for creators prioritizing video work.

In practical testing, the A6400 produces sharper, cleaner video with more versatile frame options. If your focus or side interest lies in filmmaking, the A6400 is my strong recommendation.

Battery Life and Storage: Managing Longer Shoots

Durability in fieldwork requires dependable power and ample storage options.

• Sony A6400 uses the NP-FW50 battery, rated conservatively at around 410 shots per charge per CIPA standards. Real-world use typically yielded 400-450 shots, although continuous video drastically reduces endurance. It accepts standard SD cards compatible with UHS-I speeds but only has a single slot.

• Sony A58 employs the larger capacity NP-FM500H battery, impressively rated at 690 shots, making it more reliable for long shooting days without spare batteries. It accommodates SD and Memory Stick Pro cards, typical in DSLRs.

If longer battery life is critical (e.g., event or travel photography without easy charging access), A58 could be more advantageous - although packable power banks and extra batteries mitigate this for the A6400.

Lens Compatibility and Ecosystem

Lens options define creative possibilities and investment longevity.

• Sony A6400 uses the Sony E-mount system, boasting an extensive and diverse lineup of 121 native lenses (Sony and third-party). These range from compact primes to heavy telephotos and specialized lenses, including outstanding OSS stabilization and autofocus features compatible with the camera’s sensor and AF.

• Sony A58 supports the older Sony/Minolta Alpha A-mount lenses. Though a broad range exists (143 lenses historically), production is now limited, with fewer new models released. Using adapters to mount E-mount lenses is possible but can limit AF performance.

The E-mount ecosystem’s modernity and growth clearly give the A6400 a huge advantage for future-proofing and experimentation with different optics.

Special Features Worth Highlighting

• A6400: Touchscreen with touch-to-focus, real-time tracking, animal eye AF, silent shooting with electronic shutter, joystick for AF point control, advanced connectivity including Wi-Fi, Bluetooth, and NFC.

• A58: In-body stabilization, traditional DSLR viewfinder experience, Eye-Fi wireless card compatibility for basic transfer functions.
