First Impressions: Size, Build, and Handling

Before digging into sensor sizes and autofocus, let’s talk about a practical consideration - how the cameras feel in your hands and their physical footprint.

The Samsung GX-10 is a traditional DSLR built for those accustomed to larger cameras with interchangeable lenses. It measures 142 x 101 x 70 mm and weighs 793 grams, offering robust build quality with some degree of weather sealing. The Sony HX20V, by contrast, is a pocketable compact at 107 x 62 x 35 mm and 254 grams, designed for portability and travel-friendly use.

Handling insights:

• Samsung GX-10: Its deeper grip and physical controls make it comfortable when using larger lenses. The weight and size provide stability, beneficial for manual focusing and long shooting sessions.
• Sony HX20V: Small and light, it disappears in your bag and is less intimidating to carry around all day. However, it lacks a dedicated viewfinder, which some photographers might miss.

If you prefer a tactile, robust camera that feels substantial and provides good grip for extended shooting, the GX-10 excels. If you prioritize lightness and ultra-portability without sacrificing too much functionality, the HX20V suits well.

Control Layout and Interface: Navigating the Systems

Intuitive controls affect how quickly and comfortably you can change settings on the fly. Both cameras offer manual controls but of different complexities.

Here is a top-down view comparison of the two bodies:

• Samsung GX-10 displays a traditional DSLR layout with dedicated dials for ISO, shutter speed, and aperture, along with a dedicated top LCD screen displaying critical shooting info.
• Sony HX20V streamlines controls typical of compacts - a mode dial, zoom lever, and fewer physical buttons. Its display is larger and sharper but relies on menus for more advanced adjustments.

The GX-10 will feel at home for someone transitioning from film SLRs or DSLRs of its era. The exposure triangle is more accessible, enabling faster responsiveness.

The HX20V favors simplicity and ease of use, ideal for casual photography or users intimidated by complex button layouts.

Sensor and Image Quality Breakdown

Image quality revolves heavily around the sensor’s size, resolution, and technology. This fundamental aspect influences dynamic range, noise performance, depth of field, and overall fidelity.

What does this mean in practice?

• The Samsung GX-10 uses a larger APS-C sized CCD sensor, which generally offers superior image quality, better low-light capability up to ISO 1600, and more control in post-processing thanks to RAW file support. Its sensor area is over 13 times larger than the HX20V’s, giving it considerable edge in dynamic range and noise performance.

• The Sony HX20V packs 18 megapixels on a tiny 1/2.3" sensor. While the resolution looks impressive on paper, the small sensor size limits low light performance and dynamic range, resulting in more noise at higher ISOs. Notably, it does not support RAW capture, restricting editing latitude.

If your priority is high image quality, especially in challenging lighting, portraiture with rich detail, or landscapes requiring dynamic range, the GX-10 is the more capable option. However, if you value high resolution in good lighting conditions with convenience and significant zoom reach, the Sony serves its role well.

Viewing and Compositional Tools

Composing your shot efficiently relies on viewfinder quality and rear screen usability.

• The Samsung GX-10 offers an optical pentaprism viewfinder with 95% frame coverage and ~0.64x magnification - typical for DSLRs of its time. This delivers a bright, lag-free view with a natural viewing experience preferred by many photographers.

• The Sony HX20V relies solely on a 3-inch fixed TFT LCD with 922k dots resolution. Its “XtraFine TruBlack” technology provides excellent contrast and visibility outdoors. However, no viewfinder means you rely entirely on the screen, which can be challenging in bright sunlight.

For photographers who like eye-level shooting and precise framing, the GX-10’s optical viewfinder is invaluable. If you mainly shoot at arm’s length or enjoy the convenience of live LCD framing, the HX20V’s sharp screen suffices.

Autofocus Systems and Speed

Critical for many genres, autofocus (AF) determines how swiftly and accurately your camera locks onto subjects.

• The Samsung GX-10 uses phase detection AF, typically faster and preferable for tracking moving subjects and sports photography. It lacks face detection and advanced tracking but provides manual focus overrides.

• The Sony HX20V’s contrast detection AF is slower, but benefits from face detection and basic tracking algorithms, paired with optical image stabilization.

In practical terms, the GX-10 excels at action, wildlife, and sports, where speed and reliable continuous AF are crucial. The HX20V is more suited for casual portraits and travel with steady subjects.

Burst Shooting and Shutter Capabilities

Burst rate is key for capturing decisive moments in fast-paced scenes.

• Samsung GX-10 shoots at 3 frames per second (fps), capping out its ability to track action compared to more modern DSLRs but adequate for moderate sports or wildlife.
• Sony HX20V jumps to 10 fps in continuous shooting mode, an advantage enabled by its smaller sensor and simpler data pipeline, but autofocus does not continue during burst, limiting utility on moving subjects.

Shutter speeds:

The GX-10’s faster maximum shutter speed offers more flexibility in bright conditions for wide apertures.

Flash and Low Light Performance

• Samsung GX-10 includes a built-in flash with several modes (auto, on, off, red-eye reduction), supports external flash units, and sync speed maxes out at 1/180s. It’s useful in dim conditions or as fill flash.

• Sony HX20V offers a built-in flash with a range of ~7.1 meters and slower sync options (slow sync included). It does not support external flashes.

Combined with sensor size advantages, the GX-10 has a clear upper hand in low-light shooting overall.

Video Recording Capabilities

If video is part of your creative pursuits, the differences here are stark:

• Samsung GX-10 does not support video recording at all. It’s a purely stills camera.
• Sony HX20V offers Full HD video recording (1920x1080 at 60 fps) with AVCHD and MPEG-4 formats, including optical stabilization during video capture. It features built-in GPS for geo-tagging, a boon for travel vloggers.

The HX20V caters better to casual videographers or travelers wanting high-quality video in a compact device.

Battery Life and Storage

Battery endurance impacts how long you can shoot without interruptions.

• The GX-10’s battery life specs are not clearly documented but DSLRs from its era with mid-sized batteries typically offer around 500-600 shots per charge, depending on usage.
• The HX20V boasts an estimated 320 shots per charge, reasonable for compacts, and offers a rechargeable battery pack.

Both cameras utilize SD-type memory cards, with the HX20V also supporting Sony’s Memory Stick format. Single card slot only on both, so no dual slots for backup.

Lens Ecosystem and Accessories

One major difference lies in lens versatility.

• Samsung GX-10 employs the Pentax KAF2 mount, compatible with over 150 lenses, from wide-angle primes to telephotos and macro lenses. This ecosystem enables photographers to tailor their setup to any genre or project.
• Sony HX20V has a fixed 25-500mm equivalent zoom lens, with an aperture range of f/3.2-5.8. You cannot change lenses, but the lens covers a broad focal range, suitable for travel and casual shooting.

If you want to experiment with different lenses or fine-tune your optical setup for specialties like macro or wildlife, the Samsung’s modular system wins. If you want an all-in-one solution that you just grab and go, the Sony’s lens is convenient.
