Selecting the right camera from Sony’s rich APS-C lineup requires more than just scanning specs sheets - it demands understanding how each tool performs in real-world photography scenarios, how it handles across genres, and how it fits various shooting styles and needs. In this detailed comparison, I dissect two distinctive Sony models that represent different technological eras and design philosophies: the Sony Alpha A6500, an advanced mirrorless offering from 2016, and the Sony A58, an entry-level DSLR dated back to 2013.

Having personally tested both extensively under controlled lab environments and in diverse shooting conditions, this article combines technical measurement, hands-on experience, and practical user considerations to help you discern which might be the right fit for your photography pursuits.

Form Factor, Handling & Ergonomics: Mirrorless Compactness vs DSLR Tradition

Starting with physical design, the Sony A6500 exemplifies the compact, rangefinder-style mirrorless ethos - offering a streamlined body that weighs just 453 grams and measures 120x67x53mm. This model provides a balance of portability and ergonomic grip, facilitating long shooting sessions without fatigue. The tilting 3-inch touchscreen enhances flexibility in composing images at awkward angles.

In contrast, the Sony A58 embraces the bulkier but ergonomically substantial compact SLR body, weighing 492 grams and sized 129x95x78mm. The heft and size reflect DSLR traditions, offering a deeper grip that many users find especially comfortable when pairing with larger lenses. While its 2.7-inch screen tilts for improved compositional flexibility, it lacks touchscreen capabilities - a limitation notable for quick menu navigation.

Ergonomic placement and control design further distinguish these two. Observing their top panels reveals the A6500’s modern approach, with cleanly laid-out custom buttons and a well-positioned mode dial allowing rapid exposure adjustments. The A58’s control cluster follows DSLR conventions, with a dedicated exposure compensation dial, but fewer customizable controls, reflecting its beginner-friendly market positioning.

Given these handling factors, users who prioritize compact, travel-friendly gear and a touchscreen interface will lean toward the A6500. DSLR enthusiasts or those accustomed to a more substantial grip might prefer the A58’s classical approach, though mindful of the tradeoff in size.

Sensor Technology & Image Quality: Evolution in Pixel Performance

Sony’s APS-C sensors in these cameras share a similar format but differ markedly in generation and imaging output. The A6500 packs a 24.2-megapixel Exmor CMOS sensor with 23.5x15.6mm dimensions, paired with the powerful Bionz X processor. Meanwhile, the A58 features a 20.1-megapixel CMOS sensor sized 23.2x15.4mm, processed with older circuitry.

From my lab testing against DXO Mark’s measured scores (85 for A6500 vs 74 for A58), the A6500 distinctly outperforms in key image quality parameters:

• Color Depth: The A6500 captures richer, more nuanced color data (24.5-bit vs 23.3-bit), a subtle but significant advantage for skin tones and foliage.

• Dynamic Range: At 13.7 EV, the A6500 handles silhouette details and shadows better than the A58's 12.5 EV, crucial for landscape photographers tackling high-contrast scenes.

• Low-Light Performance: The A6500’s native low-light ISO scores 1405 (higher is better), nearly doubling the A58’s 753, confirming cleaner noise handling at high ISO.

Both cameras feature anti-aliasing filters, impacting sharpness but reducing moiré. The A6500’s sensor supports native ISOs from 100-25600 (expandable to 51200), whereas the A58 tops at 16000 native (25600 boosted). This headroom gives A6500 users more flexibility when shooting in challenging lighting.

In practical terms, my comparative real-world shootouts in portrait and landscape settings consistently showed the A6500 delivering cleaner files with better tonal gradation and resolution fidelity, a clear benefit for demanding print and commercial work.

Autofocus Systems: Precision and Tracking That Matter

Autofocus is where technological leaps become immediately evident. The Sony A6500 incorporates a hybrid AF system with 425 focus points integrating on-sensor phase-detection and contrast-detection, supporting eye autofocus and continuous tracking. This high-density AF array facilitates subject detection across the frame with excellent accuracy, even in low contrast conditions.

The A58, on the other hand, relies on a more rudimentary AF system with only 15 phase-detection points (3 cross-type), and contrast detection for live view AF. While perfectly adequate for general photography and beginners, it lags behind in continuous AF speed and accuracy, especially for fast, erratic subjects, such as in wildlife or sports photography.

Neither camera offers animal eye AF - but the A6500 includes touch AF for intuitive selection on its touchscreen, enhancing usability for portrait shooters seeking reliable eye focus on human subjects.

Extensive field testing across sports and wildlife shoots demonstrated the A6500’s superior tracking reliability at 11 fps continuous shooting, markedly faster than the A58’s 8 fps. The A6500 also supports silent electronic shutter speeds up to 1/32000s, reducing vibration - a plus when capturing precise focus.

Build Quality & Weather Sealing: Ready for Adventure?

The A6500 features partial environmental sealing, designed to resist dust and moisture ingress under moderate conditions, making it a more resilient companion for outdoor and travel photography. The A58 lacks any weather sealing, a factor to strongly consider for those venturing into harsh or unpredictable environments.

Both cameras are not classified as waterproof, shockproof, or crushproof according to rigorous durability standards, so use caution in extreme conditions. That said, the A6500’s magnesium alloy chassis and sealing elements provide enhanced peace of mind compared to the mainly polycarbonate build of the A58.

LCD and Viewfinder Comparison: Composition Tools

The A6500 boasts a 3-inch tilting touchscreen LCD with 922k dots resolution that greatly improves user experience - allowing quick menu access, pinch-to-zoom image review, and touch-to-focus during live view.

The A58’s tilting LCD is smaller and lower resolution (2.7 inches, 460k dots), lacking touch capabilities, making navigation slower, especially for users accustomed to smartphones.

Electronic viewfinders (EVFs) differ as well. The A6500 features a high-resolution OLED EVF with 2.36 million dots and near 100% coverage at 0.7x magnification. The A58’s EVF is a modest 1.44 million-dot LCD style with similar coverage but 0.65x magnification.

These differences affect low-light framing and manual focusing precision, especially when paired with fast lenses.

Lens Ecosystem and Compatibility: Sony E vs Sony A Mount

Lens availability is a critical factor for investment longevity and creative flexibility. The A6500 uses Sony’s E-mount system, which supports over 121 lenses covering primes, zooms, macro, and specialty optics, including third-party options from Sigma and Tamron. Native support for modern lens features such as fast autofocus and image stabilization offers superior performance.

By contrast, the A58 employs Sony’s A-mount (legacy Minolta Alpha) lenses - over 143 options exist, but many are dated or less supported on mirrorless bodies. Furthermore, most modern fast AF lenses (like Sony G Master series) focus mainly on E-mount, leaving Sony A-mount users reliant on older optics or adapters.

For macro photography and telephotos crucial in wildlife or nature shooting, the E-mount system combined with latest OSS (optical steady shot) lenses significantly boosts the A6500’s capabilities.

Battery Life and Storage: Practical Considerations

The A58 impresses with remarkably longer battery life rated at approximately 690 shots per charge (using the NP-FM500H battery), a strong advantage for events, extended shooting days, or travel where recharging opportunities may be limited.

The A6500, while more power-demanding due to its advanced features and EVF, supports around 350 shots per charge (NP-FW50 battery), which is average for mirrorless cameras with electronic viewfinders. Supplementary battery packs or quick charging workflows become essential for heavy users.

Both support a single slot for SD or Memory Stick Pro Duo cards, compatible across SDHC and SDXC standards. Users requiring dual card slots for backup or extended storage will need to look elsewhere.

Video Capabilities: 4K Ready vs Full HD Legacy

Videographers will find the Sony A6500 significantly more capable, offering 4K UHD video capture at 30 fps using the efficient XAVC S codec with bitrates up to 100 Mbps. For serious content creators, this improvement delivers crisp, detailed footage with better color gradation and low-light noise handling. External microphone input supports high-quality audio capture.

The A58 maxes out at 1080p Full HD video at 60 fps with AVCHD or MPEG-4 encoding - a solid entry-level video solution but noticeably less future-proof in today’s 4K-dominated landscape.

Neither camera offers headphone jacks, somewhat limiting critical audio monitoring. Both lack in-body video stabilization, though lens-based OSS helps.
