Olympus SP-610UZ vs Sony SLT-A55: A Real-World Camera Comparison for 2024

Choosing the right camera in a sea of options can be daunting, especially when cameras serve drastically different purposes yet sit in overlapping price territories. Today, we’re putting two distinctly different models head to head: the Olympus SP-610UZ, a compact superzoom bridge camera designed for casual shooting with a powerful zoom, and the Sony SLT-A55, an early entrant in the translucent mirror (SLT) line aimed at entry-level enthusiasts craving DSLR features.

Having personally tested thousands of cameras over 15 years - across the rugged wilds, bustling urban scenes, bright landscapes, and studio setups - I’ll guide you through their practical strengths and limitations. We’ll look beyond just specs to reveal how each camera performs in real-world scenarios including portraits, sports, landscapes, wildlife, video, and more, while also discussing usability, ergonomics, and value.

Let’s dive in.

First Impressions and Physical Handling

When you get a new camera, the physical feel and usability sets the tone for every shoot. Neither Olympus SP-610UZ nor Sony A55 are mirrorless revolutionaries by today's standards, but each carves its niche ergonomically.

The Olympus SP-610UZ is a compact, lightweight bridge camera weighing just 405 grams. Its boxy, somewhat chunky body feels straightforward and approachable, though it’s built predominantly of plastic - which means limited weather sealing or ruggedness. Its dimensions (107x73x73 mm) make it pocket-friendly for casual outings and travel.

In contrast, the Sony A55 tips the scales at 500 grams, but its deeper, DSLR-style grip, more robust chassis, and larger body (124x92x85 mm) lend it a more professional heft and feel. It commands a presence better suited for enthusiasts serious about image quality and control. The fully articulated 3-inch screen also enhances usability for creative angles and selfies.

Looking from above, the Sony offers dedicated dials for shutter speed, aperture priority, and manual exposure. Olympus’s small sensor superzoom design means it lacks such refined manual control, catering more to auto or program modes. This difference cues who each camera serves best: the SP-610UZ is for casual shooters prioritizing zoom and simplicity, while the A55 targets photographers wanting hands-on creative exposure control.

Sensor Technology and Image Quality: The Heart of the Matter

Where these cameras diverge dramatically is their sensor technology and resulting image potential.

• Olympus SP-610UZ sports a small 1/2.3-inch CCD sensor (6.17x4.55 mm) with 14 megapixels. CCD sensors were once valued for clean color but at this size, image quality and noise performance are limited.

• Sony A55 uses a much larger APS-C CMOS sensor (23.5x15.6 mm) delivering 16 megapixels. This sensor is approximately 13 times larger in surface area, dramatically improving dynamic range, high ISO performance, and detail retention.

In real-world testing, I found the difference palpable. The Olympus excels in bright, well-lit scenes but struggles significantly in low light beyond ISO 400. Noise is noticeable, and detail softens, especially at the long end of its zoom.

The Sony’s APS-C sensor opens up creative freedom with cleaner images at ISO 3200 and even usable files at ISO 6400 in desperate low-light conditions. Its dynamic range of 12.4 EV, as measured by DxOMark, means it's better at preserving highlight and shadow details - a major advantage for landscapes or challenging lighting.

This sensor gap effectively answers one key decision factor: if image quality is paramount, especially for large prints or editing flexibility, the Sony A55 shines clearly.

Autofocus, Speed, and Burst Shooting

Autofocus system performance often makes or breaks a camera’s usefulness for action, wildlife, and sports.

• The Olympus SP-610UZ employs an 11-point contrast-detection autofocus system with no phase-detection. It’s slow to lock focus, especially in low light, and lacks continuous or tracking AF. Continuous burst is a sluggish 1 frame per second.

• The Sony A55 features a hybrid autofocus system with 15 phase-detection points plus contrast AF. This translucent mirror tech enables fast autofocus acquisition with eye detection capabilities and good accuracy in continuous focus mode. It shoots bursts up to 10 fps, which was state-of-the-art in its segment.

During my field tests photographing birds and cyclists, the Sony consistently nailed focus and followed moving subjects well, whereas the Olympus lagged behind, often hunting or missing fast action.

For wildlife and sports enthusiasts, the Sony is head and shoulders above.

Viewfinder and Screen Usability

Given these are different camera types, their viewing systems also differ.

The Olympus SP-610UZ has no viewfinder at all, relying solely on its fixed 3-inch TFT LCD with 230k-dot resolution for framing. In bright sunlight, this screen is dim and reflective, reducing usability outdoors.

The Sony A55 offers a bright, high-resolution (1150k-dot) electronic viewfinder covering 100% of the frame - crucial for accurate composition. Its fully articulated 3-inch LCD with 921k dots gives flexible tilting for low or high-angle shots.

If you shoot outdoors often or desire precise framing, the Sony’s EVF and articulating screen deliver a professional edge.

Lens Options and Versatility

Lens compatibility defines a camera’s creative and longevity potential.

• The Olympus SP-610UZ has a fixed superzoom lens covering an impressive 28-616 mm equivalent (22x zoom) at f/3.3-5.7 aperture. This immense reach is great for travel and casual wildlife but comes at a cost in image quality and low-light capability. The drawback: you cannot swap lenses, so you’re locked to this one focal range.

• The Sony A55 benefits from the Sony/Minolta Alpha mount with access to over 140 compatible lenses, from ultra-wide primes to professional-grade telephotos and fast portraits lenses. This ecosystem expands creative possibilities vastly.

That said, for travel photographers or casual users prioritizing zoom and simplicity without changing lenses, Olympus offers an all-in-one convenience.

Build Quality and Weather Resistance

Neither camera is weather sealed or ruggedized, reflecting their consumer-grade target markets.

• The Olympus’s compact plastic body feels light but can flex under pressure. Expect to protect it from dust, moisture, and impacts.

• The Sony’s more substantial build feels durable yet is still not weatherproof. For professional shoots in challenging conditions, additional protection is recommended.

Battery Life and Storage

For on-the-go photography, battery life and storage flexibility matter.

• The Olympus runs on 4 AA batteries, which can be convenient since AAs are easy to replace worldwide - even in emergencies. However, it provides around 340 shots per charge, modest by today’s standards.

• The Sony uses a proprietary lithium-ion battery (NP-FW50) with life around 380 shots - slightly better but requires careful charging.

Storage-wise, the Olympus supports SD cards, while the Sony adds Memory Stick Pro Duo compatibility - a plus for legacy users but mostly SD cards are the go-to choice.

Image Stabilization: Hands-On Impact

Both cameras have in-body image stabilization:

• Olympus uses sensor-shift stabilization effective for handheld zoom shots and macro photography.

• Sony’s sensor-based stabilization is similarly effective but benefits more from higher quality lenses with optical stabilization as well.

During handheld testing at telephoto ranges, Olympus’s IS noticeably reduced blur, but not enough to comfortably shoot indoors without flash. The Sony’s combo with fast primes offers superior sharpness handheld.

Video Capabilities: Which Performs Better?

Video features often get overlooked but can make a huge difference if you want to capture motion.

• The Olympus records HD video at 1280 x 720 at 30fps, using the Motion JPEG format. While decent for casual use, the codec is inefficient, leading to large files and limited editing options.

• The Sony supports full HD 1920 x 1080 video at 60 and 30fps, with advanced codecs (MPEG-4, AVCHD, H.264). It also has a microphone port for external audio - critical for serious video shooters. The articulated screen further eases video framing.

For creators seeking quality video, the Sony A55 is a significant step up.
