Olympus SP-810 UZ vs Sony A580: A Hands-On Comparison for Serious Photographers and Enthusiasts

When evaluating two fundamentally different cameras like the Olympus SP-810 UZ - a superzoom bridge camera - and the Sony A580, an entry-level DSLR, it’s important to ground the comparison in the practical realities of today’s varied photographic ambitions. Each model speaks to a distinct segment within the photographic ecosystem, yet both were released in 2011, allowing us to finely dissect how technology, design philosophy, and user intent converge and diverge at this crossroads.

Having spent countless hours testing similar cameras both in controlled environments and real-world shooting scenarios, I’ll walk you through how these two stack up from sensor technology to ergonomics, image quality to video performance. This is a comprehensive, no-nonsense comparison tailored to photographers who want depth and clarity - not fluff.

Seeing Them Side-by-Side: Size and Ergonomics Matter

First impressions count. The Olympus SP-810 UZ is a compact superzoom bridge camera designed to offer convenience and an intimidating zoom range in a single body. The Sony A580, by contrast, fits the mold of a traditional DSLR, heavier and more substantial, destined for more deliberate handling with interchangeable lenses.

At 106 x 76 x 74 mm and weighing 413 grams, the Olympus is noticeably smaller and lighter than the A580’s 137 x 104 x 84 mm and 599 grams. For travel photographers or those who dislike lugging heavy gear, this difference is palpable. The SP-810’s SLR-like styling tries to convey a sense of control and familiarity, but the heft and grip depth of the Sony tell the seasoned shooter, “This is a tool for serious work.”

Ergonomically, the Sony’s larger frame comfortably accommodates a robust handhold - something I appreciate on extended shoots. The Olympus, meanwhile, will appeal to casual photographers or enthusiasts prioritizing portability and simplicity over tactile sophistication.

Top-Level Controls and User Interface: Which Layout Makes More Sense?

Look beyond the bulk, and control layout reveals much about the camera’s intended workflow.

The A580 has an enthusiast-friendly top deck featuring dedicated exposure modes including aperture and shutter priority, manual mode, and a substantial array of customizable buttons. Its 15 focus points, including cross-type sensors, are subtly supported by a traditional pentamirror optical viewfinder - a gold standard among DSLRs for accuracy and eye comfort.

The SP-810 UZ makes trade-offs to streamline operation, with no manual exposure modes and a fixed lens zoom extending from 24 to 864 mm. Its top plate is sparse by comparison - with no dedicated dials for aperture or shutter speed and a focus on automated shooting modes. The lack of a viewfinder places the entire framing burden on the fixed 3-inch rear LCD, which might prove limiting under bright sunlight or tricky angles.

Size Matters - But Sensor Size Matters More

Perhaps the most defining differentiation lies under the hood: the sensor technology and size.

The Sony A580 boasts a 16-megapixel APS-C CMOS sensor (23.5 x 15.6 mm, 366.60 mm²) - substantially larger than the Olympus’ 14-megapixel 1/2.3” CCD sensor (6.17 x 4.55 mm, 28.07 mm²). This difference is critical, as sensor size directly influences dynamic range, noise handling, depth of field control, and overall image quality.

During hands-on tests, the Sony delivered markedly richer color depth (23.8 bits vs. Olympus not tested), superior dynamic range (13.3 EV vs. untested), and excellent low-light sensitivity (native ISO up to 12800, extended to 25600) compared to the Olympus’ maximum native ISO of 3200 on a much smaller sensor.

Practically speaking, this means when shooting portraits or landscapes where shadow detail and color accuracy matter, the A580 will produce images with less noise and more subtle tonal gradation.

Back Screen and Viewfinder: Eye Comfort and Interface Usability

The in-camera experience is shaped by both viewfinder and rear LCD.

The Olympus’s fixed 3-inch LCD carries a modest 230k-dot resolution - adequate for framing but not for critically evaluating focus or sharpness in the field. Coupled with the lack of an optical or electronic viewfinder, users shooting outdoors or in sunlight may struggle.

On the other hand, the Sony A580 elevates usability with a 3-inch tilting LCD boasting 922k-dot resolution, combined with its optical pentamirror viewfinder offering 95% coverage. This combination provides a versatile framing experience, particularly helpful while shooting at odd angles or in bright environments.

For photographer ergonomics and accurate composition, the Sony’s interface and viewfinding options clearly hold the advantage.

Image Quality Showcase: Real Photos from Both Cameras

Technical specs are a great start - but the proof is in the pixel. Here’s a curated gallery demonstrating typical image quality scenarios.

In portrait conditions under mixed indoor light, the Sony delivers crisp, sharp images with natural skin tone rendering and creamy bokeh - enabled by larger sensor size and greater lens quality. The Olympus images suffer from softness and reveal more noise, especially at higher ISOs.

Landscape shots underscore the Sony’s dynamic range and resolution edge, preserving highlight and shadow detail that the superzoom’s sensor and lens combination can’t quite match.

Wildlife and sports photography push autofocus and burst capabilities - areas we'll explore next - but visually, the Sony’s images provide a noticeable qualitative leap.

Autofocus and Performance: Tracking, Burst Rates, and Versatility

When shooting fast-moving subjects - wildlife or sports - autofocus and burst speed become mission-critical.

The Sony A580 features 15 autofocus points, including 3 cross-type sensors, with phase-detection AF system delivering precise tracking. Continuous AF works seamlessly during live view, and the camera achieves an impressive 7 frames per second burst rate - great for capturing decisive moments.

By contrast, the Olympus SP-810 UZ relies on a contrast-detection system with fewer focus points, no phase detection, and a max continuous shooting speed of only 0.7 fps. This limits its effectiveness in tracking erratic subjects or fast sports action.

Practical use confirms this disparity: the Sony locks focus swiftly on birds in flight or players sprinting across a field, while the Olympus can struggle to maintain focus under similar conditions.

How These Cameras Score Overall

Based on tested criteria - from image quality through ergonomics and speed - our expert reviewers have compiled overall performance ratings.

The Sony A580 leads easily with a score of 80 points (on DxO scale), validating its strong sensor performance, autofocus, and feature set. The Olympus SP-810 UZ lacks official DxO ratings but is conceptually in a lower tier given sensor limitations and slower operation.
