Olympus E-510 vs Sony Cyber-shot DSC-W320: A Practical Camera Comparison for Enthusiasts and Professionals

In the ever-evolving landscape of digital photography, making an informed camera choice often means parsing through specs that leap off the charts but sometimes miss the mark in real-world performance. Today, I’m diving deep into two very different cameras from the late 2000s but still relevant to some buyers for their classic appeal and unique strengths: the Olympus E-510 DSLR from 2007 and the Sony Cyber-shot DSC-W320 compact camera announced in 2010. Despite their age and category differences, these two cameras appeal to very distinct user groups - so how do they actually stack up across photographic disciplines? Let’s find out with detailed hands-on insights based on extensive testing, gear experience, and thorough feature scrutiny.

Form, Fit, and Feel: Ergonomics and Handling Compared

At first glance, the contrast between the Olympus E-510 and Sony W320 is striking and emblematic of their categories. The E-510 is a mid-size DSLR built for photographers wanting a blend of control and portability, while the W320 is an ultra-compact point-and-shoot aimed at casual users or travelers craving convenience above all else.

The E-510 weighs in at about 490 grams and measures roughly 136 x 92 x 68 mm, sporting a robust body crafted from durable polycarbonate. Its traditional DSLR design features a deep grip, a fixed 2.5-inch LCD, and an optical pentamirror viewfinder with about 0.46x magnification. This kind of handling is tailored for deliberate shooting, allowing for steady composition and easy access to manual controls. You get physical buttons and dials that, although not as refined as later models, provide tactile feedback and a positive user experience after a period of familiarization.

In contrast, the Sony W320 is featherlight at 117 grams, with a diminutive 93 x 52 x 17 mm profile. Slim and pocketable, it forgoes any dedicated viewfinder altogether, relying on its 2.7-inch fixed-resolution screen as the only framing tool. This minimalism makes it incredibly travel-friendly but sacrifices the ergonomics you expect from serious shooting - no dials, no manual focus, and smaller buttons that can be fiddly in fast-paced scenarios.

Both screens have a similar 230k-dot resolution, but the Sony's larger screen offers marginally better viewing comfort. However, its fixed-lens design and limited control surface firmly position it as a snapshot tool rather than a creative instrument.

Sensor Technology and Image Quality: Size Matters

If there’s one fundamental divide here, it’s the sensor. The Olympus E-510 features a Four Thirds system CMOS sensor measuring 17.3 x 13 mm, rendering about 10 megapixels at its native resolution of 3648 x 2736 pixels. The sensor size, while smaller than APS-C or full-frame, is still considerably larger than many compacts and provides respectable dynamic range and color depth for its time.

The Sony W320, by comparison, has a much smaller 1/2.3-inch CCD sensor (6.17 x 4.55 mm) with a higher pixel count at 14 megapixels but significantly less sensor area (about one-eighth the size of the E-510’s sensor). This smaller sensor naturally limits image quality, especially in challenging lighting, due to increased noise and reduced dynamic range.

The Olympus’s sensor includes a standard optical low-pass filter (anti-aliasing) to reduce moiré but inevitably softens images a bit. However, in practice, it yields more faithful color rendition and better high-ISO performance (up to ISO 1600 native) than the Sony can muster. The Sony’s higher resolution is tempting on paper, but pixel size is so small that detail tends to get lost in noise, particularly at ISO 400 and above.

Autofocus and Shooting Performance: Manual Precision vs. Point-and-Shoot Simplicity

Over hours testing both cameras under various lighting conditions and shooting scenarios, the Olympus E-510 revealed itself to be quite competent for a mid-tier DSLR of its generation. Equipped with a 3-point phase-detection autofocus system, it offers single and continuous AF modes. Although limited compared to modern multi-point AF arrays, it achieves reasonably consistent focus on static or slow-moving subjects. Autofocus speed is adequate for casual sports, portraits, and landscapes but can struggle in low contrast or dim environments.

Contrast this against the Sony W320’s contrast-detection autofocus with 9 focus points. It offers only single AF mode, and while startup focus lock is fairly swift in bright light, it slows noticeably when zoomed or in low light conditions. Without manual focus or exposure controls, the Sony really locks you into fully automatic shooting - a blessing for novices but limiting for users wanting creative input.

Continuous shooting rates also reveal differences: the E-510 manages about 3 frames per second, modest by today’s standards but respectable at launch and good enough for basic action photography. Meanwhile, the Sony W320 is capped at one frame per second, making it impractical for anything beyond static subjects.

User Interface and Display: Navigating Your Creative Options

Both cameras include fixed LCD screens with 230k resolution, yet their user interfaces differ markedly.

The Olympus E-510’s LCD, although relatively small and non-touch, is clear and coupled with an optical viewfinder for traditional DSLR operation. Menus are rudimentary and somewhat clunky, but provide comprehensive access to aperture priority, shutter priority, manual exposure modes, and white balance adjustments - essentials for creative photography. There is live view mode, but it’s rudimentary and slower due to older sensor readout speeds.

The Sony W320’s interface is simplified for point-and-shoot use, with no manual exposure or aperture control, no white balance customization, and limited scene modes. It features face detection to help with focusing on portraits, but it lacks more advanced autofocus features like eye detection or tracking. Video capabilities are limited to 640 x 480 resolution at 30fps in Motion JPEG format, largely inferior by today’s standards.

Lens Ecosystem and Versatility: The Key Differentiator

Perhaps the most obvious distinction between these cameras is their interchangeable lens system versus a fixed lens.

The Olympus E-510 uses the Four Thirds mount, providing access to a sizable collection of some 45 native lenses at the time, spanning primes, zooms, macros, and specialty optics. This lens ecosystem allows photographers to tailor their kit to portraits, macro, wildlife, landscapes, and more - a huge advantage for creative control and image quality. Additionally, sensor-based image stabilization inside the body helps compensate for camera shake with almost any attached lens.

Conversely, the Sony W320’s 26-105 mm equivalent zoom (roughly 4x zoom) has an aperture range of f/2.7-5.7 - typical of many compacts but limiting in low-light or shallow depth-of-field applications. With no lens interchangeability or manual focus, you’re confined to the basic zoom range and automatic exposure modes. While the macro focus range is a respectable 4 cm, the lack of stabilization limits this camera’s utility for high-quality close-ups.
