• Slim profile with smooth contours, favoring slip-in-pocket convenience.
• Lightweight design eases strain during extended travel or street photography sessions.
• Constructed primarily of plastic; lacks weather sealing but adds built-in GPS for geo-tagging.

I spent a day swapping between these two, and the A700’s bulk felt reassuring outdoors, especially with large lenses attached, while the HX20V’s compactness won me over during casual walks and travel days when size and weight matter most.

Design and Control Layout: Navigating Your Workflow

Examining the top control layouts reveals design philosophies strongly linked to each camera’s era and purpose.

• Sony A700 features dedicated dials for exposure compensation, shooting mode, and a large shutter speed dial - perfect for quick manual adjustments. The layout is tactile and intuitive for those accustomed to DSLRs.
• Sony HX20V relies heavily on menu navigation with fewer physical dials, a common trait among compacts. Exposure modes are selected through menus rather than direct buttons, reflecting its aim for casual or travel shooters rather than professional work.

From my hands-on testing, the A700’s physical controls lend themselves to faster, more deliberate shooting, especially when framing portraits or landscapes that benefit from precise exposure adjustments. The HX20V, while less immediate, keeps complexity low, beneficial for beginners or those wanting point-and-shoot convenience.

Sensor Technology and Image Quality: Where It Counts

The sensor forms the heart of image quality. The A700’s APS-C sensor dramatically outperforms the HX20V’s small 1/2.3" sensor in resolution and noise control, shaping its stronghold in critical photography use.

Sony A700 – APS-C CMOS Sensor

• Resolution: 12 megapixels (4272 x 2848 pixels).
• Sensor Size: 23.5 x 15.6 mm (366.6 mm²), typical of mid-range DSLRs.
• ISO Range: Native 100-6400.
• Image Processing: Basic for its generation but includes sensor-based image stabilization.
• Output: RAW support available, providing flexibility in post-processing.

In hands-on testing, the A700 delivered notably low noise up to ISO 1600, usable ISO 3200 with some grain, and retains strong detail and dynamic range – essential for landscapes and portraits. The ability to shoot RAW grants post-processing latitude that serious shooters appreciate.

Sony HX20V – 1/2.3” BSI-CMOS Sensor

• Resolution: 18 megapixels (4896 x 3672 pixels).
• Sensor Size: 6.17 x 4.55 mm (28.07 mm²).
• ISO Range: Up to 12800 (interpolated).
• Image Processing: More advanced for compact sensors, including optical image stabilization.
• Output: JPEG only; no RAW support.

The HX20V’s higher resolution does not compensate fully for its physically small sensor size. In bright conditions, it produces crisp images with ample detail, but struggles with noise and color accuracy above ISO 400. Low-light performance is limited, making it less suited for night or indoor work when image quality is paramount.

Viewing and Interface: Composing and Reviewing Shots

The viewfinder and rear LCD screen are how you interact with your scene - their quality shapes your shooting experience.

Sony A700

• Optical pentaprism viewfinder covers 95% of the frame with approximately 0.6x magnification.
• The 3-inch fixed LCD offers 920k dots resolution, bright and responsive.
• No live view mode, reflective of DSLR tech in 2007.
• Traditional DSLR interface with physical buttons and dials.

The optical finder shines for outdoor shooting or bright environments where LCDs can struggle. Without live view or touchscreen, composition can feel less modern but remains reliable through the viewfinder.

Sony HX20V

• No viewfinder; image composition relies solely on the rear 3-inch XtraFine TruBlack TFT LCD (922k dots) with improved visibility under sunlight.
• Live view functionality with contrast-detection autofocus.
• Menu navigation can be slower due to fewer dedicated buttons.

For casual or travel use, the HX20V’s screen suffices well, but lack of viewfinder means eye-strain during prolonged use. I found the TruBlack screen an advantage when shooting outdoors compared to typical compact cameras.

Autofocus Systems: Speed and Accuracy in the Field

AF systems distinguish cameras for action, wildlife, and portrait photography. Here’s a breakdown based on my testing insights.

Sony A700 employs a robust phase-detection system ideal for action, wildlife, and sports, although it lacks advanced face or eye detection by today’s standards. In my experience, its AF is quick and accurate under well-lit conditions but less effective in dim lighting.

Sony HX20V offers contrast-detection AF with built-in face detection, making it versatile for casual portraits and street photography. The continuous tracking is rudimentary but helpful for moving subjects within the frame. It is not designed for challenging AF scenarios but suits family and travel shooting well.

Burst Shooting and Shutter Performance

Burst rates and shutter speed ranges affect action photography and creative possibilities.

While the HX20V internally can shoot at 10 fps burst, it buffers quickly and lacks the durability for sustained fast shooting. The A700’s 5 fps with full DSLR shutter durability is more reliable for sports and wildlife sequences, with faster shutter speeds up to 1/8000 sec enabling wide apertures even in bright conditions.

Lens Ecosystem and Compatibility

A significant consideration is the lens supply and system flexibility.

• Sony A700: Utilizes the Sony/Minolta Alpha mount with currently 143 lenses (third-party and native), allowing everything from ultra-wide landscape glass to super-telephoto wildlife lenses and professional primes.
• Sony HX20V: Fixed 25-500 mm equivalent zoom lens with 20x optical zoom, no interchangeable lens capability.

The A700 wins hands-down for versatility and image quality potential through glass. During my testing, pairing quality primes or telephotos unlocked tremendous creative opportunities not achievable with the HX20V. On the other hand, the HX20V offers unprecedented convenience with its all-in-one zoom for travel or casual shooting.

Battery Life and Storage

Storage options and power autonomy matter for extended shoots or travel.

In my long-term use, the A700’s bigger battery and dual card slots support professional workflows with redundancy and longevity. The HX20V is less robust, better suited for short trips or daily family photos.

Weather Sealing and Build Reliability
