Sony A580 vs Sony H400: An In-Depth Comparison for Photography Enthusiasts

Selecting the right camera is a task fraught with compromises, especially when dealing with products that serve divergent photography needs. The Sony Alpha DSLR-A580 ("Sony A580") and the Sony Cyber-shot DSC-H400 ("Sony H400") represent two fundamentally different approaches within the Sony imaging lineup. The A580 is a mid-2011 entry-level DSLR boasting a larger APS-C sensor and interchangeable lenses, while the 2014 H400 is a bridge camera featuring a compact sensor with an extremely versatile fixed superzoom lens.

In this detailed comparison, I draw on my extensive hands-on testing and industry-standard evaluation protocols to provide an authoritative analysis across key performance categories, technical specifications, and user scenarios. Beyond specifications, this article will consider ergonomics, system ecosystems, and real-world shooting performance across a variety of photography disciplines - enabling enthusiasts and professionals to make an informed, practical purchasing decision.

Physical Design and Handling: Form Factor Versus Portability

Ergonomics and physical dimensions significantly influence shooting comfort and operational control. The Sony A580 is a traditional DSLR with a well-defined grip and a robust body, whereas the H400 adopts a bridge-style, SLR-like form factor designed to emulate DSLR aesthetics but with compromises on size and weight.

Sony A580:

• Dimensions: 137 x 104 x 84 mm
• Weight: 599 g (body only)
• Solid grip with tactile buttons and dials
• Tilting 3.0-inch LCD with 922k dots resolution

Sony H400:

• Dimensions: 130 x 95 x 122 mm (notably deeper due to lens barrel)
• Weight: 628 g (integrated zoom lens)
• Fixed 3.0-inch LCD with 460k dots - lower fidelity
• SLR-like styling, but controls are simplified and smaller

The A580’s body provides a more balanced hand-feel due to the weight distribution enabled by interchangeable lenses, offering better stability during longer handheld shooting sessions. Its 3-inch tilting screen and optical pentamirror viewfinder provide flexibility in composing shots at various angles, though the viewfinder has a modest 95% coverage and 0.53x magnification limiting critical framing precision.

In contrast, the H400’s bridge camera form provides high zoom versatility in a single package but suffers from a heavier front bias due to an enormous 63.3x zoom lens (25-1550mm equivalent). The fixed screen of the H400, while sufficiently large, is half as dense regarding pixel count as the A580, affecting live view clarity and focus checking. Its electronic viewfinder is basic - 201k dots resolution - which is subpar compared to the DSLR’s optical finder especially in fast-action scenarios.

Overall, the A580’s ergonomics prioritize enthusiast handling with physical controls and manual shooting ease, whereas the H400 trades off manual input sophistication for sheer zoom range and compactness.

Sensor Technology and Image Quality: APS-C Versus Small Sensor CCD

Central to image quality is the sensor size and technology. The A580 sports a 16.2MP APS-C CMOS sensor measuring 23.5 x 15.6mm (sensor area approx 366.6 mm²), while the H400 uses a 20.1MP 1/2.3-inch CCD sensor of 6.17 x 4.55mm (about 28 mm²).

Sensor Size and Impact: The A580’s APS-C sensor is over 13 times larger in surface area than the H400’s CCD, resulting in vastly superior light-gathering capability. This difference manifests in reduced noise, improved dynamic range, and superior low-light performance for the A580.

Image Resolution: While the H400 claims a higher megapixel count (20.1MP vs 16.2MP), this advantage is outweighed by the sensor size. The smaller sensor's higher pixel density can lead to increased noise and reduced dynamic range.

Image Quality Metrics: Drawing on DxO Mark data, the A580 achieves an overall score of 80, with excellent color depth (23.8 bits) and dynamic range (13.3 EV). The H400 has not been tested by DxO, but typical performance of 1/2.3" CCD sensors places it well below the APS-C standard. Noise performance degrades rapidly above ISO 800 on the H400, whereas the A580 maintains usable ISO performance up to 3200 and beyond.

Anti-aliasing Filters: Both cameras include anti-aliasing filters which slightly soften fine detail but prevent moiré patterns. Given the sensor sizes and pixel density, the A580’s filtering is less of a detriment considering its higher quality image reproduction.

This fundamental sensor disparity makes the A580 more suitable for demanding disciplines like portraiture, landscapes, and professional work requiring RAW output and post-processing latitude. The H400 excels for casual photography with emphasis on zoom reach, but with compromises in fine detail and noise.

Autofocus Systems: Phase Detection DSLRs Versus Contrast Detection Bridge Cameras

Critical in capturing sharp images is the autofocus (AF) system’s design and performance.

Sony A580:

• Hybrid AF system combining phase detection (15 AF points, 3 cross-type) for fast focus acquisition and continuous AF tracking
• Face detection and live view continuous AF
• Eye detection AF is absent, but multi-area and center-weighted focusing aid composition control

Sony H400:

• Contrast-detection AF only, with no phase detection points
• Face detection included, but focus tracking is limited
• Total number of AF points unspecified, with reduced accuracy under low contrast or fast motion

In practice, the A580's dedicated phase detection system enables faster, more accurate AF lock and tracking for moving subjects. This makes it better suited for wildlife, sports, and action photography where predictive focus tracking is vital.

The H400’s contrast-detection AF is slower and prone to hunting, especially at long zoom focal lengths where depth of field narrows dramatically. This reduces its effectiveness in fast-paced environments, but can be adequate for stationary or slow subjects.

Viewfinder, LCD Screen, and User Interface: Operational Visibility and Control

The user interface impacts shooting efficiency and composition accuracy in all environments.

Sony A580:

• Optical pentamirror viewfinder provides natural, lag-free viewing but limited 95% coverage and 0.53x magnification
• 3-inch tilting LCD with 922k dots for high-resolution image review and live view, beneficial in awkward angles
• Extensive physical controls with dedicated mode dial, exposure compensation, and quick access buttons

Sony H400:

• Electronic viewfinder with 201k dots resolution is functional but low-resolution, leading to pixelated preview images
• Fixed 3-inch Clear Photo LCD with 460k dots is less detailed
• Simplified control layout with fewer dedicated buttons limiting rapid adjustments; zoom dial dominates interface

The A580’s larger screen resolution and tilting mechanism provide users with greater compositional flexibility, crucial for macro, landscape, or off-angle shots. The optical viewfinder, while less bright or sharp compared to modern pentaprisms or EVFs, outperforms the H400's electronic viewfinder which can suffer delay and less dynamic precision under challenging lighting.

Lens Ecosystem and Versatility: Interchangeable Lenses versus Ultra-Long Superzoom

One of the defining advantages of DSLRs is the ability to interchange lenses to match creative and technical needs.

Sony A580:

• Ability to use prime lenses, macro, telephoto, and wide-angle
• Supports sensor-based image stabilization effective with non-stabilized lenses

Sony H400:

• Fixed superzoom lens: 25-1550mm equivalent (63.3x zoom)
• Maximum aperture varies from f/3.4 (wide) to f/6.5 (tele)
• Optical image stabilization compensates for camera shake, especially critical at extreme zoom

The H400’s enormous zoom range enables extreme telephoto reach without swapping lenses or carrying bulk, ideal for casual wildlife or travel photography when swapping lenses is impractical.

However, the variable aperture and small sensor limit low-light performance and depth-of-field control. The A580’s lens flexibility supports professional workflows, allowing users to adapt optics for portrait, macro, landscape, or sports shooting. Additionally, prime lenses with wide apertures generate superior bokeh and subject isolation capabilities.
