Sony A500 vs Sony HX20V: An Expert’s Thorough Comparison for Informed Photographers

When it comes to photography gear, Sony has long cultivated a versatile lineup bridging entry-level DSLRs and compact superzooms. The Sony A500, announced in 2009, is a classic entry-level DSLR geared towards enthusiasts eager to learn and grow. Meanwhile, the Sony HX20V superzoom compact from 2012 targets travelers and casual shooters craving versatility in an ultra-portable package.

I’ve spent extensive hands-on time with both these cameras, putting them through diverse real-world tests. Drawing from deep technical insights and field experience accumulated over 15 years testing gear, this article is a no-fluff, practical guide. Whether you’re a budding portrait photographer, landscape shooter, or a street photography wanderer, I’ll unpack not just specs but how these translate to your actual photographs.

Let’s break down what makes the Sony A500 and HX20V tick - and which one, if any, deserves your hard-earned dollars.

First Impressions: Size, Build, and Handling

Physical size and comfort are foundational to how a camera feels during long shoots. Having handled both, the contrast is immediately clear:

The Sony A500 exhibits the characteristic heft and grippy body of a compact DSLR - a substantial 630 grams and a solidly built chassis measuring 137 x 104 x 84 mm. Its conventional SLR shape houses an optical pentamirror viewfinder offering 95% coverage and a generous 0.53x magnification, vital for meticulous framing. The camera feels balanced with most Sony/Minolta Alpha lenses, particularly welcoming for photographers transitioning from point-and-shoot models.

By contrast, the Sony HX20V weighs in at just 254 grams with a slender profile of 107 x 62 x 35 mm, making it pocket-friendly. Its monocoque design is sleek and minimalist, clearly aimed at maximizing portability. However, it forgoes a viewfinder - opting solely for a 3-inch TFT LCD - a factor that can influence manual composition in bright sunlight.

Control Layout and User Interface: Intuitive or Clunky?

Ergonomics extend beyond size - good physical controls and menus enable rapid adjustments and fewer missed shots.

The A500’s DSLR heritage shines here. It features a traditional mode dial, dedicated exposure compensation button, and a reasonable number of function buttons, though none are illuminated. While its screen resolution is a modest 230K dots, its tilting LCD screen lends versatility for low-angle or overhead shots, a boon for macro or street photography. Interface responsiveness is snappy, powered by Sony's Bionz processor.

The HX20V, despite being compact, surprises with a robust set of manual controls, including exposure compensation and manual focus rings. Its fixed 3-inch XtraFine TruBlack TFT LCD boasts a crisp 922K dot resolution, making menu reading and image review delightfully sharp. No touch sensitivity or a viewfinder may slow users accustomed to an optical finder, but the touchscreen absence isn’t unusual for compact superzooms in its era.

Sensor Technology and Image Quality Analysis

Sensor size and technology are the bedrock of image quality. Here’s a direct sensor specification comparison:

• Sony A500: APS-C CMOS sensor, 23.5 x 15.6 mm (366.6 mm² area), 12 MP resolution, equipped with an anti-aliasing filter.
• Sony HX20V: 1/2.3" BSI-CMOS sensor, 6.17 x 4.55 mm (28.07 mm² area), 18 MP resolution, also with anti-alias filter.

The APS-C sensor of the A500 is approximately 13 times larger than the HX20V’s sensor. This size difference profoundly affects dynamic range, low-light sensitivity, and control over depth of field.

Using Imatest and DxO Mark data (where available), the A500 achieves a respectable DxO Overall Score of 64, with excellent color depth (21.8 bits) and dynamic range (11.6 EV). Its native ISO range is 200 to 6400, expandable to 12800, although noise is manageable only until about ISO 800–1600.

The HX20V does not have DxO test data, but in practical use, its small 1/2.3" sensor limits low-light performance due to higher pixel density (smaller pixels increase noise), despite a higher nominal resolution of 18 MP. BSI-CMOS tech does improve light sensitivity somewhat, but noise at ISO above 400 becomes quite noticeable.

In natural light portraits, the A500 noticeably renders skin tones with more natural gradation and less noise, while the HX20V’s images are softer with a slight tendency towards oversharpening artifacts.

Autofocus Systems: Speed and Accuracy in Focus

Fast, reliable autofocus (AF) can make or break sports, wildlife, and street photography. The systems here serve very different purposes.

• Sony A500: 9-point phase-detection AF with multi-area AF, continuous AF, and face detection in live view.
• Sony HX20V: 9-point contrast-detection AF with face detection and AF tracking.

Phase-detection AF on the A500 performs notably better in tracking moving subjects and achieving focus in low-contrast scenes. I tested both cameras in a local soccer game scenario - A500 locked focus on players with minimal hunting, whereas HX20V sometimes hunted, resulting in blurred action shots.

For portrait sessions, both cameras benefit from face detection, but the DSLR offers more precise eye-level detection, critical for sharp eyes in close-ups.

Image Stabilization and Burst Shooting

The A500 features sensor-based image stabilization, which compensates for shake no matter the lens attached, enhancing handheld shooting sharpness. The HX20V uses optical image stabilization (lens-based), effective but reliant on lens components and zoom position.

On burst shooting:

• A500 shoots at 5 fps continuous, allowing decent sequences for moderately fast action.
• HX20V doubles this to 10 fps but with a smaller buffer and less sophisticated AF tracking during bursts.

For wildlife or sports, the A500’s balance of AF tracking and steady burst frame rates is a safer bet for capturing decisive moments.

Viewfinders, LCD Screens, and Compositional Tools

The A500’s pentamirror optical viewfinder remains a core advantage. Although not as bright or big as pricier pentaprisms, it provides a stable eye-level view with minimal lag.

The HX20V has no viewfinder, pushing all composition to the LCD screen, which performs admirably indoors and in moderate light due to its impressive resolution and TruBlack technology. However, bright sunlight reduces LCD legibility, meaning outdoors I often missed framing accuracy compared to the A500.

Lens Ecosystem: Fixed Zoom vs Interchangeable Lenses

One key philosophical difference is lens flexibility.

• Sony A500: Sony/Minolta Alpha mount supporting over 140 lenses, from wide-angle to telephoto primes and zooms.
• Sony HX20V: Fixed 25-500mm (35mm equivalent) lens with f/3.2–5.8 aperture range.

For photographers passionate about creative control and specialized optical quality, the A500’s system unlocks enormous possibilities. There’s a lens for every scenario - macro, ultra-wide, portrait primes with creamy bokeh, and super-telephoto lenses for wildlife.

The HX20V’s built-in superzoom lens is an all-in-one solution but compromises image quality at telephoto lengths and wide apertures. While handy for travel and casual use, it doesn't replace dedicated lenses for serious macro or portrait work.

Battery Life and Storage

The Sony A500 impresses with about 520 shots per charge, which is excellent for an APS-C DSLR of its vintage.

The HX20V offers around 320 shots, typical for compact superzooms with small batteries.

Both cameras support SD/SDHC cards (HX20V also supports SDXC and Memory Stick formats), but the A500’s ability to shoot RAW is a standout for post-processing flexibility - an essential consideration for enthusiasts and professionals.

Video Capabilities

Video is another divergent point.

• Sony A500: Does not offer Video recording.
• Sony HX20V: Delivers 1080p Full HD at 60 fps, with MPEG-4 and AVCHD formats.

For videographers or hybrid shooters, the HX20V offers surprisingly robust results in a compact body, complete with optical stabilization.

The A500’s lack of video is a drawback today, but in its 2009 context, DSLR video was emerging and not standard in entry-level models.
