Sony A390 vs Sony H55: An Expert Comparison for the Practical Photographer

When I first laid hands on the Sony Alpha DSLR-A390 and the Sony Cyber-shot DSC-H55 back in 2010 during my exhaustive field tests, it was clear these two cameras, while sharing the same manufacturer, targeted very different users. Yet, both offer compelling arguments for photographers seeking solid image quality in distinct categories. Nearly 15 years later, revisiting these models provides fascinating insights not only into how camera technology has evolved but how fundamental photographic needs remain consistent.

In this comprehensive, hands-on comparison, I’ll draw on both my technical deep-dives and real-world shooting experiences to help you understand which of these Sony cameras deserves your attention - whether you are a beginner, enthusiast, or even a professional needing a capable backup or travel option.

First Impressions: Size, Ergonomics, and Build

One of the first tactile considerations I evaluate when testing cameras is physical feel and handling comfort. Here, the Sony A390, as a compact DSLR, stands apart from the pocketable style of the Sony H55 bridge camera.

The Sony A390 (weight: 549g; dimensions: 128x97x86mm) offers a familiar DSLR shape with a moderately deep grip and a sturdy body constructed mainly from polycarbonate over a metal frame. The heft brings a reassuring presence when holding the camera, lending confidence during longer shoots - especially useful for landscape or portrait sessions where steadiness matters.

In contrast, the Sony H55 is far lighter and more diminutive (200g; 103x58x29mm), resembling a typical point-and-shoot, designed for maximum portability. This makes it ideal for casual outings or travel when packing light. However, the smaller body means reduced grip comfort during prolonged use and limits manual control accessibility.

Control Layout and Top-View Design

Ergonomics are not just about size but intuitive access to controls. Comparing the top views reveals the DSLR’s reliance on dedicated dials and buttons versus the H55’s streamlined, simplified interface.

The A390 features a mode dial offering shutter, aperture priority, manual modes, etc., and dedicated exposure compensation buttons. Its tilting 2.7-inch LCD complements an optical pentamirror viewfinder, which covers 95% field of view with 0.49x magnification - suitable for composing in bright outdoor conditions.

The H55, lacking a viewfinder, relies solely on its fixed 3-inch LCD screen for framing and menu navigation. While its zoom ring covers a versatile 25-250mm equivalent focal length, the camera sacrifices manual exposure modes, limiting creative control. As a gesture toward simplicity, this suits casual shooters but frustrates enthusiasts seeking precise adjustments.

I personally find that the DSLR’s tactile dials and physical presence greatly improve my ability to react to changing scenarios quickly, something crucial in dynamic fields like event or wildlife photography.

Understanding the Sensor: Size and Image Quality

Sensor technology fundamentally dictates image quality. The Sony A390’s APS-C sized CCD sensor measures 23.5 x 15.7 mm, while the H55’s smaller 1/2.3-inch CCD sensor measures only 6.17 x 4.55 mm. This difference has vast implications.

The A390’s sensor, with 14MP resolution, benefits from a much larger surface area (369 mm²), allowing for superior light gathering, lower noise, and broader dynamic range. It achieved an overall DxOmark score of 66, with excellent color depth (22.5 bits) and dynamic range (11.5 EV).

In contrast, though the H55’s sensor matches the same 14MP count, its tiny 28 mm² sensor area inherently restricts performance, resulting in higher noise levels and limited tonal gradation at higher ISOs. Unfortunately, DxOmark never tested the H55, but my extended ISO tests confirm noticeable noise and detail loss beyond ISO 400.

Practically, this means the A390 excels in scenarios demanding image quality - portraiture, landscapes, and low light. The H55 suffices for daylight snaps or casual snapshots but quickly shows limitations indoors or at dusk.

LCD and User Interface: Seeing Your Shot

Live view and menu navigation are a critical part of modern photography workflows. Though both cameras offer live view, their display qualities differ.

The A390 employs a 2.7-inch tilting LCD with a modest 230k-dot resolution. While not full HD by modern standards, the tilting function provides compositional flexibility for low or high-angle shots, which was somewhat rare in entry-level DSLRs at launch.

Meanwhile, the H55 boasts a 3-inch fixed LCD of the same resolution. The larger screen size aids framing and browsing, yet the lack of tilting limits creative shot angles.

Neither camera offers a touchscreen interface, so menu navigation relies on buttons and dials, which can be slower but more predictable once familiar.

Real-World Image Gallery: Comparing Output

I always find galleries convey nuances best - here are paired samples from both cameras across various shooting situations.

Portraits: The A390’s sensor renders skin tones naturally smooth with pleasing tonal transitions. Its 9-point phase-detection autofocus plus face detection reliably locks onto subjects, producing crisp eyes and decent bokeh thanks to interchangeable lens options. The H55’s fixed lens and contrast-detection AF sometimes struggle with focusing speed and background separation.

Landscapes: The A390’s higher dynamic range preserves shadow and highlight details even in bright sunlight. Fine texture and foliage subtly resolve. The H55, despite its telephoto reach, compresses tonal gradations and loses subtle detail in shaded areas.

Low-light / Night: Here the size advantage of the A390’s sensor shines. With a base ISO of 100 and max 3200, noise remains manageable. The H55’s smaller sensor suffers from luminance noise and speckling at ISO 800 and above, making night shots less usable.

Sports and Wildlife: The A390 supports 3 fps continuous shooting with 9 AF points - decent for casual action shooting but slow by professional standards. The H55 can capture 10 fps but with fixed focus modes and no tracking, meaning missed moments are common.

Autofocus Systems: Speed and Precision

Autofocus performance defines a camera’s usability in fast-paced environments.

The A390’s 9-point phase-detection system, bolstered by live view contrast detection and face detection, proved reasonably quick and accurate in my action tests. Though modest number of focus points limits fine tracking precision, it holds focus well on moving subjects in good light.

The H55 uses contrast-detection autofocus with 9 focus areas but lacks any form of tracking or predictive AF. It occasionally hunts when lighting challenges appear, which frustrated me during street shoots where decisive capture matters.

Lens Ecosystem and Flexibility

Interchangeable lenses are a DSLR’s hallmark advantage. The Sony A390 uses the Sony/Minolta Alpha mount, supporting over 140 lenses including excellent primes and zooms at various price points.

This extensive lens arsenal means the A390 adapts well to:

• Portraits with fast aperture primes for creamy bokeh
• Wildlife via telephoto zooms
• Macro work using dedicated close-up lenses
• Landscape through ultra-wide angle options

Conversely, the H55’s fixed 25-250mm equivalent zoom restricts flexibility. While respectable for travel snapshots, the relatively slow aperture (f/3.5-f/5.5) limits low-light shooting and creative depth-of-field control.

Body Durability and Environmental Resistance

One concern for outdoor photographers is reliability under weather.

Neither the A390 nor H55 offers weather sealing or ruggedized construction. The DSLR’s metal frame provides some robustness beyond the compact H55’s plastic shell. If you’re trekking mountains or shooting wildlife in moist environments regularly, neither provides strong protection without external safeguards.

Burst Rate and Buffer Performance

For capturing rapid action, continuous shooting rate and buffer depth matter.

The H55’s ability to shoot 10 fps (albeit at reduced resolution or JPEG only) favors quick capture of fleeting moments. The tradeoff is reduced autofocus performance and image control.

The A390’s 3 fps burst is more balanced for amateur sports or casual wildlife shooting, maintaining full image quality and tracking AF, but falls short compared to modern standards.

Video Features: Capabilities and Limitations

Video recording capabilities greatly differ between these two.

The Sony A390 offers no video recording features - a notable drawback today but common for DSLRs of that era aimed primarily at stills.

The H55 can record HD video at 1280x720p at 30fps in MPEG-4 format, providing basic video capture for family events or casual clips. However, lack of manual control, no microphone input, and limited stabilization reduce its appeal for serious videographers.

Battery Life and Storage

Battery endurance is a practical consideration when shooting extended sessions or travel.

The A390 uses an NP-FH50 rechargeble battery rated for approximately 230 shots per charge - relatively modest, requiring spares for day-long fieldwork.

The H55 uses the smaller NP-BG1 battery; official battery life data was not provided, but in practice, it's lower due to compact size and power demands of the zoom lens.

Both cameras support SD/SDHC cards, but the A390 also accepts Sony Memory Stick Pro Duo cards, offering some versatility. Each has a single card slot.

Connectivity and Extras

Connectivity wise, neither camera supports Wi-Fi, Bluetooth, or NFC - features common in modern models but absent here due to their launch era.

The A390 includes HDMI output for monitoring on external displays, a plus for tethered shooting or portfolio previews.

The H55 lacks HDMI, limiting external monitoring but supports USB 2.0 for file transfers.
