Head-to-Head: Sony Alpha DSLR-A290 vs Sony Cyber-shot DSC-W320 – An In-Depth Comparison for Every Photographer

Selecting the right camera has always been about matching your photographic vision to the tool that best realizes it. When comparing cameras as different - yet both from Sony - as the Sony Alpha DSLR-A290 and the Sony Cyber-shot DSC-W320, the decision isn’t merely about specs on paper. It’s about understanding how each performs in real-world use across varied photography disciplines, and whether they fit your technical needs and shooting style.

Having spent countless hours in camera labs and field tests with hundreds of models, I’ll walk you through this detailed comparison. With first-hand experience, technical expertise, and lots of side-by-side shooting, I’ll unpack these two Sony cameras from sensor and autofocus to ergonomics, and everything in between.

Let’s dive in!

Getting Acquainted: Form Factor and Handling – DSLR vs. Ultracompact

At first glance, these cameras couldn’t be more different physically and ergonomically.

The Sony A290 is a classic entry-level DSLR featuring a 23.5x15.7mm APS-C CCD sensor - a substantial size that fundamentally influences its imaging potential. It comes in a traditional SLR form factor complete with an optical pentamirror viewfinder and offers manual control dials and buttons. The body measures 128x97x86mm and weighs 549g, affording decent presence in the hands, especially when combined with interchangeable lenses from Sony’s extensive Alpha lineup.

On the other end, the Sony W320 is an ultracompact point-and-shoot, ultra portable at just 93x52x17mm and a featherweight 117g. Its fixed 26-105mm-equivalent lens sits behind a tiny 1/2.3-inch sensor. This camera is designed for quick grab-and-go shooting, making it an appealing option for casual shooters or travelers prioritizing pocketability above all else.

From an ergonomic standpoint, the A290 has traditional DSLR heft and grip contours that promote stability and rapid manual settings adjustment - critical in demanding shooting conditions. The W320’s compact body delivers excellent portability but at the expense of manual control and handling comfort during extended use or with telephoto zoom.

Interface and Design: Controlling Your Creativity

Ergonomics aside, how you interact with controls can make or break a photography experience.

The A290 sports a familiar top layout, complete with a mode dial offering aperture and shutter priority, manual modes, and various scene presets. It has dedicated buttons for ISO, exposure compensation, and playback. The rear features a fixed 2.7-inch LCD with 230k dots resolution - adequate though modest by today’s standards.

The W320, meanwhile, pares back physical controls dramatically. It lacks any manual exposure modes or advanced settings dials, aiming instead at fully automatic shooting with some scene modes and basic flash controls. It shares the same size screen specs but no viewfinder at all.

This difference matters hugely if you want to actively shape images rather than passively capture. The tactile, feedback-rich control scheme of the A290 is a big win for enthusiasts, while the W320 emphasizes simplicity and ease-of-use.

Sensor Technology and Image Quality: The Heart of the Matter

This is where the story unfolds in terms of ultimate image fidelity.

The A290 packs a 14-megapixel APS-C CCD sensor - large for its time and category - delivering high resolution (4592x3056 pixels) and decent dynamic range. Sony’s CCD tech in this camera provides good native color depth (22.6 bits on DxO’s color depth scale), along with a respectable dynamic range (~11.5 EV) and an ISO ceiling of 3200 (native, no boost).

In contrast, the W320 has the same megapixel count but on a much smaller 1/2.3-inch sensor measuring just 6.17x4.55mm, typical of ultracompacts. This results in far less usable dynamic range and poorer low-light performance - the sensor area is nearly 13 times smaller than the A290’s, a fundamental limitation in image quality potential.

These sensor disparities translate to real world differences:

• Portraits: The A290’s larger sensor offers smoother skin tones, better gradation, and more detail retention - critical for professional or serious portraiture. The W320 struggles with noise quicker and delivers flatter color rendition under challenging lighting.

• Landscapes: The APS-C sensor of the A290 captures broad tonal ranges with less artifacting and higher resolution preserving fine detail and texture in foliage or cloudscape. The W320, while capable under bright daylight, succumbs to softness and noise in shadows or highlights.

• Low light and Night: The gap widens further when shooting handheld in low light or astrophotography. The A290’s larger pixels and higher max shutter speed (up to 1/4000s) afford more creative control with less ISO noise, while the W320 maxes out at 1/1600s max shutter speed and produces more grainy, muddled results.

Autofocus and Shooting Speed: Capturing the Moment

While sensor technology lays the groundwork for image quality, autofocus and shooting speed define how effectively the camera can seize fleeting moments.

The A290 uses a 9-point phase-detection autofocus system, all cross-type focus points being unknown but offering more precise and faster acquisition typical of DSLRs at the time. It supports continuous AF during burst shooting capped at a modest 3 fps, which proved sufficient for beginner wildlife and sports photographers in controlled environments.

On the other hand, the W320’s autofocus relies on contrast detection with 9 AF points (somewhat rudimentary) and slower focusing speed due to sensor and processor limits. Continuous AF and tracking are absent, and burst shooting stalls at just 1 fps.

This distinction significantly impacts:

• Wildlife: Fast-moving subjects demand focus speed and tracking. The A290’s phase-detection AF fares much better, especially with telephoto lenses. The W320 simply isn’t up to these tasks.

• Sports: Similar story - accurate tracking amidst complex motion on the A290 provides an edge.

• Street and Travel: The W320’s quick startup and pocketability serve casual snapshots, but its AF speed occasionally lags, particularly in low contrast or dim scenes.

Lens Ecosystem and Creative Flexibility

One of the strongest arguments for the A290 lies in its Sony/Minolta Alpha mount compatibility, unlocking a vast catalog of lenses - from cheap M42 adapters to modern Sony and Zeiss optics.

This flexibility opens doors for:

• Macro with dedicated close-up lenses
• Highest quality portraits with fast prime lenses
• Wildlife and sports via super-telephoto lenses
• Landscape options with ultra-wide angle lenses

The W320, with a fixed, compact 26-105mm equivalent zoom lens, excels only at general-purpose shooting. While this suits everyday casual use, it severely limits creative potential and optical quality - especially at long focal lengths where softness and chromatic aberration creep in.

Screen, Viewfinder, and User Interface: Seeing Your Shot

Both cameras have a similar 2.7-inch fixed LCD with 230k dots, but the A290 shines with an optical pentamirror viewfinder offering 95% frame coverage and 0.55x magnification. For many photographers, having a viewfinder is essential for stable composition and shooting in bright daylight.

The W320, lacking any viewfinder, forces reliance on the rear screen, which can be difficult under direct sunlight.

From experience, I can say that the A290’s dual option to shoot via viewfinder or screen is an important ergonomic advantage.

Build Quality and Durability

Neither model is weather-sealed or ruggedized, reflecting their entry-level and consumer-targeted design.

The A290, however, feels sturdier and more substantial, with a build more suited for extended handling and varied outdoor shooting scenarios. The W320’s plastic-y ultracompact design, while attractive for portability, makes it more vulnerable to everyday bumps and drops.

Battery Life and Storage

Battery life reflects usage patterns:

• A290: Rated approximately 290 shots per charge using the NP-FH50 battery pack. Modest but workable for casual to moderate shooting sessions. DSLR users often carry extras.

• W320: Official battery life is unspecified, but users generally report shorter lifespans, typical of ultracompacts with smaller batteries (NP-BN1).

Both cameras utilize single card slots supporting SD and Sony Memory Stick formats, though the A290’s larger images and RAW files necessitate larger, faster cards.

Video Capabilities and Connectivity

Here, the gap widens again:

• A290: Offers no video recording whatsoever - limiting its use solely to still photography.

• W320: Provides low-res 640x480 @ 30fps video in Motion JPEG format. While hardly professional, it can handle quick casual videos.

Neither camera supports wireless connectivity, Bluetooth, GPS, or advanced ports. Both offer USB 2.0 and HDMI outputs, but no microphone or headphone jacks.

Image Samples and Performance Ratings: Seeing Is Believing
