Olympus SP-620 UZ vs Sony A700

Choosing Between the Olympus SP-620 UZ and the Sony A700: A Deep-Dive Comparison

Selecting the right camera is a critical step for photographers, whether you’re an enthusiast seeking your next upgrade or a professional assessing tools for specialized use. Today, I’ll be comparing two very different cameras from distinct eras and categories: the compact superzoom Olympus SP-620 UZ (2012) and the advanced mid-size DSLR Sony Alpha DSLR-A700 (2007). On paper, they serve very different audiences, but through detailed hands-on testing and technical analysis, I will help clarify which camera might fit your needs best.

First Impressions: Size, Handling, and Ergonomics

When I first handled the Olympus SP-620 UZ and the Sony A700 side by side, the physical differences were immediately clear.

The Olympus SP-620 UZ is a compact superzoom camera designed for portability and simplicity. It weighs roughly 435g, measures 110x74x74mm, and features a fixed lens covering an extraordinary focal length range (25-525mm equivalent). Its small size and light weight make it comfortable to carry around on casual outings or travel without extra lenses.

In contrast, the Sony A700 is a much larger DSLR with a weight around 768g and dimensions 142x105x80mm. It has a substantial grip, extensive button layout, and a sturdier build quality that you can feel immediately. This camera is designed for users comfortable with manual controls and who want the tactile feedback of a DSLR body.

Ergonomically, the Sony offers superior control customization, which I found invaluable during extended shoots. The Olympus, with its fixed lens and minimal physical controls, is more straightforward but limited in manual adjustment - a deliberate design choice for convenience over flexibility.

Control Layout and User Interface

Navigating through camera menus and accessing vital functions can shape your shooting experience significantly.

The Sony A700's top plate features dedicated dials for shutter speed, exposure compensation, and drive modes - key for quickly adapting settings in dynamic environments. The buttons are logically grouped and backlit, which is a blessing during low-light shoots.

The Olympus SP-620 UZ, with a fixed 3-inch TFT LCD screen (230k dots resolution), opts out of an electronic viewfinder entirely, relying solely on the rear LCD for framing. This can be challenging in bright sunlight. The camera lacks manual exposure modes, shutter priority, or aperture priority, emphasizing point-and-shoot operation. Controls are minimal, focusing on digital menus rather than physical dials.

The Sony also features a pentaprism optical viewfinder offering 95% coverage and 0.6x magnification, letting you compose shots with clarity and speed - something absent in the Olympus.

Sensor Technology and Image Quality

Sensor size and technology fundamentally impact image quality and noise performance.

The Sony A700 sports a 12MP APS-C CMOS sensor sized 23.5x15.6mm (~366mm²), which is roughly 13 times larger in area than the Olympus’s tiny 1/2.3” CCD sensor (6.17x4.55mm, 28mm², 16MP).

This difference explains why the Sony consistently delivers higher image quality, better low-light performance, and broader dynamic range. At base ISO 100, the Sony’s sensor captures fine detail with less noise. Its maximum ISO stretches to 6400, useful for demanding indoor or nighttime conditions.

By contrast, the Olympus maximizes its small sensor through an extended zoom lens and built-in sensor-shift image stabilization (crucial to avoid blur with long zooms). However, high ISO is limited to ISO 3200, and image noise becomes noticeable relatively early due to sensor size and older CCD technology.

The Sony’s support for RAW files compared to Olympus’s JPEG-only output is a significant advantage for photographers who want greater post-processing latitude. RAW also preserves more dynamic range and color information.

LCD Screen and Interface Experience

Screen quality and usability are critical for composing shots, reviewing images, and navigating menus.

The Sony features a 3.0” LCD with significantly higher resolution (920k dots) versus the Olympus’s 230k dot display. This allows for sharper image playback and easier fine detail inspection without external devices.

However, both cameras lack touchscreen capabilities and live view, which feels dated by current standards but was common for their respective release periods.

Note the Sony’s lack of live view contrasts with modern DSLRs but does not hamper its optical viewfinder experience. The Olympus relies entirely on the LCD, which can be tough to see clearly outdoors or in complex lighting.

Image Samples: Real-World Output Comparison

Technical specs paint one picture, but real-world image quality tells another story.

In controlled testing across various scenarios:

• Portraits: The Sony’s larger sensor rendered natural skin tones with smooth gradation while allowing excellent background separation with compatible lenses. Its 11-point phase-detection AF provided quick, precise autofocus, though eye detection is not present. Olympus’s smaller sensor resulted in more compressed tones and less natural bokeh. Face detection helped keep focus on subjects, but image quality suffers in low-light indoor portraits.

• Landscapes: Sony’s APS-C sensor offers richer dynamic range and finer detail, preserving shadow and highlight information superbly on RAW files. Olympus’s JPEG compression and smaller sensor fell short on subtle tonal transitions and sharpness, but its ultra-telephoto reach enabled capturing distant landscape features others would miss.

• Wildlife: Olympus’s extreme 21x zoom (25–525mm equivalent) is a major selling point here, enabling long-distance photography without changing lenses. However, autofocus speed felt sluggish, especially tracking moving animals. The Sony’s telephoto lenses deliver superior optical quality and faster AF due to phase detection but require investment in compatible glass.

• Sports: Sony’s 5 fps burst shooting maintained consistent focus on static or slow-moving subjects but lacked sophisticated AF tracking. Olympus’s burst rate specifications are not advertised, generally lower due to simpler hardware. Low light performance favors Sony.

Performance Ratings and Professional Potential

An important aspect when comparing is overall handling under pressure – durability, battery life, and workflow integration.

Sony’s A700 scores higher overall, thanks to better sensor, build, and manual controls that professionals demand. It has environmental sealing protecting against dust and moisture, vital for outdoor professionals.

The Olympus lacks weather sealing and utilizes AA batteries - less convenient and heavier in the long run, while Sony employs a proprietary rechargeable lithium-ion battery offering more cycles and runtime.

Storage-wise, Sony provides dual card slots supporting Compact Flash and Memory Stick - facilitating redundant backups and more storage options. Olympus supports SD cards only in a single slot.
