Samsung GX-10 vs Sony A390: Which DSLR Should You Choose for Your Photography Journey?

Choosing your next DSLR camera is an exciting yet sometimes overwhelming decision. Today, we’re comparing two notable APS-C sensor DSLRs from Samsung and Sony: the Samsung GX-10 (announced 2006) and the Sony Alpha DSLR-A390 (launched in 2010). Both cameras have carved places in the mid-level to entry-level DSLR markets and represent significant technology approaches from their respective manufacturers.

We’ll dive into every critical aspect - from sensor technology and autofocus performance to ergonomics, lens ecosystems, and real-world usability. Drawing on years of hands-on testing across photography disciplines, this detailed comparison will help you identify which camera aligns best with your creative ambitions and practical needs.

First Impressions: Size, Build, and Handling

The physical feel and handling of a camera profoundly impact your shooting experience. The Samsung GX-10 is a mid-size DSLR with a more substantial build, weighing about 793g and measuring 142x101x70mm. It yields a reassuring grip and solid presence in hand, catering well to users who prefer that robust DSLR feel without excessive size.

The Sony A390, on the other hand, is a more compact DSLR at 549g and sized 128x97x86mm. It’s notably lighter and smaller, enhancing portability for travel or street photography, but with a slightly less substantial grip.

Comparing top control layouts reveals Samsung sticks to traditional DSLR ergonomics with a top display and more straightforward button placements optimized for quick access - ideal if you prefer tactile control clarity during shoots.

Sony’s A390 features a tilting 2.7" LCD and a modernized button arrangement, trading off some tactile feedback for a sleeker design and better composition versatility (tilting screen helps for shooting at unusual angles).

In low-light or fast action, the physical button arrangement and ergonomics matter a lot - not just specs. Beginners especially will appreciate the Sony’s user-friendly interface, but the GX-10’s heft can provide more stability for steady shots and heavier lenses.

Sensor and Image Quality: Detail, Color, and ISO Performance

Looking under the hood, both cameras sport APS-C sensors with a 1.5x crop factor and CCD technology. However, the variations in resolution and native ISO capabilities influence image sharpness and noise handling.

The Sony A390’s 14-megapixel sensor provides more detailed image resolution, ideal for cropping or large-format prints. Its expanded max ISO of 3200 allows greater flexibility in low-light shooting with reduced noise, thanks partially to newer sensor design and image processor (Bionz).

The Samsung’s 10 MP resolution is very respectable, with a max native ISO of 1600 matching the period's performance limits but lagging behind the Sony in high ISO noise control.

Unfortunately, neither camera supports video capture - a downside today, but expected as both predate video-heavy DSLR trends.

For landscape and travel photography, the superior 14 MP in the Sony aids crisp detail, while the Samsung’s weather-sealed body (more on that later) offers environmental resilience.

Check out this side-by-side sensor size and resolution comparison:

Autofocus System: Speed, Accuracy, and Usability in Real World

Autofocus speed and accuracy are crucial whether you’re shooting wildlife, sports, or portraits. Both cameras feature phase-detection AF systems suited for DSLR mirror-based focusing, but details matter.

Samsung’s 11-point AF array provides solid coverage but lacks face detection or advanced tracking features. For portrait sessions, manual fine focus helps compensate, though eye-detection autofocus is missing.

Sony’s 9-point AF might seem less numerous but gains with face detection during Live View mode, which makes it friendlier for portrait and event photography where you need reliable focus on human subjects.

However, both cameras do not feature animal eye AF or contrast-detection AF, so wildlife photographers wanting precise focus on moving animals might find limitations.

In fast burst or sports scenarios, both cameras offer a 3fps continuous shooting rate - serviceable but not fast for aggressive action shooting.

Given the Sony’s live view AF advantage (a significant usability boost), it holds an edge in AF flexibility for amateurs transitioning to advanced techniques.
