Olympus SP-620 UZ vs Sony A330: The Real-World Camera Comparison You’ve Been Waiting For

If you’re diving into the maze of camera choices on a tight (or just sensible) budget, the Olympus SP-620 UZ and Sony Alpha A330 might have crossed your path as contenders. Both cameras target the entry-level buyer but come from very different worlds - one a superzoom compact, the other an entry-level DSLR. After spending many hours with both, I’m here to dissect their differences and help you decide which deserves a place in your camera bag.

I’m not here to fluff specs or sprinkle jargon like fairy dust. These cameras were tested under an array of photography scenarios, from portrait lighting and wildlife bursts to travel light-packing and night astrophotography. So buckle up, fellow photo nerds, while we take a close look at how these two stack up.

First Impressions: Size, Build, and Handling

Compact vs DSLR - The Form Factor Debate

The Olympus SP-620 UZ is a compact beast with a serious zoom, while the Sony A330 carries the typical DSLR heft and shape. Let’s start with the ergonomics, because if a camera feels like a brick or a toy, you'll put it down before firing a shot.

The Olympus measures a neat 110 x 74 x 74 mm and weighs just 435g (4 AA batteries included), so it shines in pocketability, especially for travel and street photography. On the flip side, the Sony A330 is noticeably bigger at 128 x 97 x 71 mm and heavier at 529g (including NP-FH50 battery), typical for DSLRs. It fits comfortably in your hands with well-placed grip contours and clubs for thumbs, making extended shooting less strenuous if you have bigger palms.

The build quality on both is plastic-heavy but feels reasonably solid for their price brackets. Neither offers weather sealing - something worth noting if you shoot outdoors often. The Sony’s DSLR design naturally conveys more confidence in durability but don’t expect it to survive a torrential downpour without a rain cover.

Control Layout and User Interface: How Intuitive Are They?

Photographers don’t want to wrestle with menus in the middle of a decisive moment. I measured response times, button placements, and ease of access to critical controls.

The Sony A330 sports a classic DSLR control scheme with dedicated dials for shutter speed, aperture, and dedicated function buttons. Its tilting 2.7-inch LCD with 230k dots helps with shooting at tricky angles. However, despite its DSLR status, the Sony’s joystick for autofocus point selection was somewhat clunky, and there’s no touch screen, which is a shame in 2024.

The Olympus SP-620 UZ opts for a fixed 3” TFT LCD with the same resolution. Its lack of manual focus and limited exposure control can frustrate advanced users. The SP-620 lacks the tactile feedback of physical dials and relies heavily on menu diving. For beginners or casual shooters, this isn’t a dealbreaker but pros might find it limiting over time.

Overall, the Sony provides superior manual control sophistication, while the Olympus focuses on simplicity and portability.

Sensor Size and Image Quality: The Heart of the Matter

No amount of fancy features will rescue a camera with a poor sensor. Let’s talk about sensor technology, resolution, and the impact on image quality.

Sensor Specs in a Nutshell

• Olympus SP-620 UZ: Uses a small 1/2.3” CCD sensor measuring 6.17 x 4.55 mm (sensor area: 28.07 mm²) at 16 megapixels.
• Sony A330: Larger APS-C sized CCD sensor at 23.5 x 15.7 mm (sensor area: 368.95 mm²), 10 megapixels.

The enormous size difference - more than 13 times larger sensor area in the Sony A330 - has significant implications:

• Dynamic Range: The Sony wins hands down with a reported DxOMark dynamic range of 11.5 EV vs untested (but generally limited) range on the Olympus.
• Low Light Performance: The APS-C sensor’s larger photosites reduce noise and improve ISO performance, as backed by Sony’s DxO low-light ISO of 535 (better noise handling).
• Color Depth: Sony scores well in color accuracy and depth (22.4 bits).
• Resolution vs Quality: Despite the Olympus boasting 16MP, higher pixel count on a tiny 1/2.3" sensor often translates to smaller pixels, more noise, and less detail retention than a well-implemented 10MP APS-C sensor.

In practical use, you’ll notice the Sony’s images are cleaner, with richer tonal gradations, especially in shadow and highlight detail - essential if you’re serious about print or post-processing flexibility.

Viewing Experience: Screens and Viewfinders Compared

Knowing what you’re shooting and composing your shot matters. The Olympus relies on its LCD, while the Sony has a DSLR optical viewfinder.

The Olympus’s 3” fixed TFT LCD is reasonably sharp for its class but lacks brightness and contrast for outdoor use. No live histogram or data overlays of note.

The Sony A330 features a 2.7” tilting LCD. Tilting is hugely helpful when shooting from low or high angles, a feature the Olympus lacks. Most importantly, the Sony has a pentamirror optical viewfinder covering 95% of the frame at 0.49x magnification - a boon for clear, lag-free composition.

Having that real optical viewfinder changed my experience when tracking moving subjects or shooting under bright sunlight. The Olympus SP-620’s absence of any viewfinder makes it difficult to compose flawlessly in intense sun.

Autofocus and Shooting Performance

When it comes to catching fleeting moments - be it a sporting event or your pet mid-leap - AF speed, accuracy, and burst rate are paramount.

• Olympus SP-620 UZ: Uses contrast-detection autofocus with face detection and 5.8x zoom reach.
• Sony A330: Hybrid autofocus with 9 AF points using both contrast and phase detection, offering superior speed and tracking.

Burst shooting is a clear differentiator:

• Olympus does not publish continuous shooting specs but is known for being sluggish, designed more for casual use.
• Sony A330 shoots at 3 fps, modest by today’s standards but good enough for casual action, and with the ability to manually control focus.

The Sony’s phase-detect AF shines when tracking moving subjects, and the 9-point AF array provides coverage versatility. The Olympus’s zoom reach is impressive but focusing can lag or hunt, especially in low light.

Lens Systems and Versatility

The Olympus SP-620 UZ comes with a fixed 21x optical zoom lens (25-525mm equivalent), so while you get massive reach, you’re locked into the built-in lens’s quirks and limitations, such as slower max apertures (f/3.1-5.8) across the range.

The Sony A330, being an interchangeable lens DSLR with a Sony/Minolta Alpha mount, enjoys access to a vast ecosystem of over 140 lenses - including fast primes, macros, and professional zooms. The ability to tailor your glass makes this a flexible system for growing photographers.

Real-World Shooting Scenarios: Practical Use Cases

Portrait Photography

• Sony A330: Provides excellent skin tone rendering due to larger sensor and RAW support. The camera’s manual exposure modes and selective AF points allow precise eye detection focus, delivering crisp portraits with creamy DSLR bokeh.
• Olympus SP-620 UZ: Limited control and a smaller sensor mean portraits lack shallow depth-of-field ‘pop.’ Face detection helps but bokeh is less pleasing and skin tones can look flatter.

Landscape Photography

• Sony A330: The bigger sensor with better dynamic range captures landscapes with richer detail and depth. The tilting screen aids composition on uneven terrain.
• Olympus SP-620 UZ: Good for general snaps but sensor noise and limited exposure control reduce flexibility especially in high contrast scenes.

Wildlife and Sports

• Olympus SP-620 UZ: Mega zoom helps capture distant wildlife but AF sluggishness compromises action shots reliability.
• Sony A330: Faster AF and continuous shooting better suited for sports, though 3 fps is basic. Lens choice is critical here.

Street Photography

• Olympus SP-620 UZ: Compact size and silent operation work for discretion, but zoom lens is bulky.
• Sony A330: More noticeable presence but superior image quality.

Macro Photography

• Olympus: Impressive 1cm macro focus distance, benefiting close-up shooters.
• Sony: Dependent on lens choice; can be excellent with dedicated macro glass.

Night and Astro Photography

• Sony: Superior high ISO performance and manual exposure modes make it the obvious choice.
• Olympus: High noise at elevated ISOs limits nocturnal shooting.

Video Capabilities

• Olympus SP-620 UZ: Shoots HD 720p at 30fps with H.264. No external mic support limits audio quality.
• Sony A330: No video recording capabilities.

Travel Photography

• Olympus: Light, compact, massive zoom – perfect for one-lens solution travel.
• Sony: Bulkier, heavy but versatile with lenses; better image quality.

Professional Use

Neither camera is a powerhouse for pro work, but the Sony’s RAW support and larger sensor give it an edge in semi-pro workflows.

Battery Life and Storage

• Olympus: Uses 4x AA batteries, which is great for field-swappers and emergency power grabs - minus rechargeable convenience.
• Sony: Proprietary NP-FH50 battery offers 230 shots per charge - typical DSLR life but less convenient if you forget to bring spares.

Both use a single SD card slot; Sony adds Memory Stick Pro Duo compatibility (a bit of a legacy quirk).

Connectivity and Extra Features

The Olympus offers Eye-Fi wireless SD support for photo transfers, plus HDMI output. Honda-notch connectivity but useful.

The Sony A330 lacks any wireless features but offers HDMI out and USB 2.0.

Price and Value: Which Camera Packs the Best Punch?

The Olympus SP-620 UZ typically comes in around $199, making it an attractive “superzoom on a budget.”

The Sony A330, priced closer to $545 used or new old stock, expects more from you but delivers a much stronger imaging tool.

My Personal Take

Having tested thousands of cameras, I find the Sony A330 to be a far sturdier photographic partner with images that stand the test of serious post-processing demands. The Olympus SP-620 UZ is a charming budget zoom compact but feels like a fixed-lens consumer ‘toy’ in comparison, best suited for very specific needs.

If I were buying today for learning or long-term use, I’m taking the Sony. But if I’m a tourist or cheapskate craving an all-in-one zoom, the Olympus earns a spot in my pocket.

If you want me to dive deeper into any use case or lens pairing for the Sony A330, or image samples under varied light, just holler. Remember, there’s no one-camera-fits-all but knowing what each excels at makes you a sharper buyer.

Happy shooting!
