Choosing Between the Olympus SP-800 UZ and Sony A580: A Deep Dive Into Two Distinct DSLR-Style Cameras

In the complex landscape of digital cameras, selecting gear that fits your photographic style and budget is no small feat. Today, I put side-by-side two cameras that satisfy very different user needs yet sometimes get cross-shopped - the Olympus SP-800 UZ, a compact superzoom from 2010, and Sony’s 2011 entry-level DSLR, the Alpha A580. Though their designs and target audiences almost couldn’t be more different, understanding the strengths and limitations of each will help you identify when either could be a smart choice.

Across comprehensive testing protocols spanning studio and real-world scenarios, I evaluated everything from the sensor performance to ergonomics across all major photographic disciplines. Whether you're a travel shooter needing versatility or an aspiring landscape photographer wanting better image quality, this guide draws on fifteen years of hands-on expertise to unpack how these cameras perform - and, importantly, where compromises come into play.

The Cameras At a Glance: Design and Handling

Before the pixels count or autofocus lock, first impressions often come down to feel and ergonomics. The Olympus SP-800 UZ is a compact superzoom with a fixed lens and a relatively chunky, but pocketable body. Meanwhile, the Sony A580 sports the bulkier build and traditional prism-style profile of an entry-level DSLR.

Olympus SP-800 UZ

• Compact and weighty for its category (455g), fits well in hand with a firm grip ridge.
• Solid, all-plastic construction feels consumer-grade but sufficiently durable.
• Fixed 28-840mm equivalent superzoom lens provides incredible reach without swapping lenses.
• 3-inch fixed LCD offers reasonable viewing but low resolution (230k dots).

Sony A580

• Larger dimensions typical of DSLR design (599g), comfortable for extended handheld shooting.
• More robust build with DSLR-style grip and traditional shutter button placement.
• Interchangeable lens mount (Sony/Minolta Alpha) opens access to a broad range of high-quality optics.
• 3-inch tilting LCD at 922k dots, providing greater flexibility and sharper preview.

The Sony’s traditional DSLR control layout shines with dedicated dials for shutter speed, aperture, and exposure compensation - valuable for manual exposure fans. The Olympus takes a minimalist approach with fewer dedicated controls, suitable for shooters favoring simplicity but restricting manual creativity.

My Take: If physical handling and control customization are priorities, especially for manual shooters, the Sony A580 holds a clear advantage. The Olympus’s compactness and zoom range offer portability but with less tactile control.

Sensor Technology and Image Quality: The Heart of the Matter

At the core of any camera’s photographic output is its sensor. The Olympus packs a 1/2.3-inch 14MP CCD sensor, common in compact cameras designed for broad zoom ranges. The Sony employs a larger APS-C CMOS sensor with 16MP resolution, a significant leap in sensor size and image potential.

Olympus SP-800 UZ: Small Sensor, Big Zoom

• Sensor size: 6.17 x 4.55mm (1/2.3”)
• Resolution: 14 MP
• Sensor type: CCD
• ISO sensitivity: 64-3200 (native), limited to ISO 1000 in boosted modes

The smaller sensor inherently limits dynamic range and noise handling. I noticed fine detail rendering falls short under low-light or high-contrast scenarios since dynamic range ranges are narrow and shadows quickly lose detail. The CCD sensor delivers decent color but with noise creeping in at higher ISOs, limiting practical use beyond ISO 400.

Sony A580: Larger Sensor Superiority

• Sensor size: 23.5 x 15.6mm (APS-C)
• Resolution: 16 MP
• Sensor type: CMOS
• ISO range: 100-12800 (native), expandable to 25600

The A580’s APS-C sensor benefits include richer tonal gradation, better low-light performance, and wider dynamic range (measured by DXO at 13.3 EV) - essential advantages I observed when shooting landscapes or indoor portraits. It also supports RAW shooting, giving post-processing latitude not available on the Olympus.

Real-World Implications

In daylight scenarios or casual snapshots, Olympus may suffice, especially given the incredible zoom. But for photographers needing nuanced image control or shooting conditions demanding fidelity, the Sony’s sensor offers vastly superior image quality and flexibility.

Autofocus Systems and Speed: Chasing the Moment

Autofocus speed and accuracy often make or break a camera’s utility in wildlife, sports, or street photography. I compared their AF systems under controlled and dynamic settings:

The Sony’s hybrid AF notably outperforms the Olympus, with faster lock times and more reliable subject tracking - critical for action or wildlife shooting. Olympus autofocus can lag in low light or challenging focus transitions.

Face detection on the Sony enhances portrait shooting precision, while the Olympus lacks this, making eye focus less reliable.

Viewfinder and LCD: Composing and Reviewing Shots

Composition comfort varies widely depending on viewfinder and screen quality.

The Olympus SP-800 UZ lacks an electronic or optical viewfinder, relying entirely on its low-res fixed LCD, which challenges composition in bright daylight or fast capture moments.

The Sony A580’s optical pentamirror viewfinder covers 95% of the frame with good brightness, offering near real-time composition feedback. This DSLR-typical viewfinder remains usable in almost any light condition.

Its tilting high-res LCD aids live view shooting from creative angles while enabling effective HTML review.
