Olympus SZ-30MR vs Sony W620: A Full-Spectrum Comparison for Enthusiasts and Professionals

In the crowded marketplace of compact cameras aimed at casual users and enthusiasts who demand versatility in a pocket-friendly form factor, the Olympus SZ-30MR and Sony Cyber-shot DSC-W620 are two intriguing contenders. At first glance, both are small-sensor compacts sporting fixed zoom lenses and straightforward controls, but they target subtly different user priorities.

Having tested both models extensively, spending hours pushing their limits from macro detail to telephoto reach, I’m ready to unpack how these cameras really perform across photography disciplines - and, crucially, who should consider each one.

Let’s dive deep: what do they offer beyond specs? How do their sensors behave under demanding conditions? What about autofocus, ergonomics, and image quality nuances that really matter when you’re out shooting? My goal is to equip you with knowledge grounded in hands-on experience, trusted evaluation methods, and practical advice. Let’s demystify these cameras.

A Tale of Two Compact Bodies: Size, Ergonomics and Handling

The very first thing a photographer notices is how a camera feels in hand - and these two make remarkably different impressions.

The Olympus SZ-30MR is a compact superzoom, accommodating an impressively long 25-600mm equivalent lens in a relatively chunky body measuring 106x69x40 mm, weighing a solid 226 grams. This heft adds a reassuring grip and steadiness. I particularly appreciated the firm thumb rest molding and well-placed mode dial that, though limited in pro-grade controls, boosts confidence when zooming or shooting quickly.

In contrast, the Sony W620 presents a distinctly smaller, slimmer silhouette (98x56x20 mm, just 116 grams) - truly pocketable, even in tight jeans or a small handbag. While it sacrifices some grip ergonomics for portability, this camera appeals to minimalists or street photographers who prize discretion above all.

Careful observation of the top view reveals Olympus’s more tactile dials and physical zoom rocker - offering better control fluidity - versus Sony’s simpler layout relying on button presses and a smaller zoom toggle.

For a shooter who values uninterrupted, ergonomic handling during long sessions or tightly framed wildlife snaps, the SZ-30MR’s body design clearly excels. Meanwhile, the W620’s svelte build suits casual day-trippers or snap-happy travelers who want a “throw-and-go” solution.

Sensor and Image Quality: CMOS Versus CCD in Small Sensor Territory

Examining the image sensor tech and resolution is a vital step because it underpins image fidelity, low light performance, and creative flexibility.

Both cameras employ the same sensor size: the standard 1/2.3-inch sensor measuring 6.17 x 4.55 mm (about 28mm² area). However, here’s where their designs diverge:

• The Olympus SZ-30MR uses a 16MP CMOS sensor with an antialias filter, which tends to offer better noise control and dynamic range at higher ISOs. Olympus coupled this with their TruePic III+ image processor, a mature system optimized for noise reduction and subtle color gradation.

• Conversely, the Sony W620 features a 14MP CCD sensor, also filtered for anti-aliasing, offering excellent color rendition but generally lagging behind CMOS technology in noise handling and speed.

In low light tests, it was clear the Olympus’s CMOS sensor retained detail and reduced noise effectively up to ISO 800, beyond which grain begins to creep in - typical of small sensors. The Sony’s CCD sensor, while respectable, showed increased noise at lower ISOs approaching 400, limiting its usability in dimmer environments.

Dynamic range assessments - critical for shooting landscapes or high contrast scenes - also favored the SZ-30MR by a small but noticeable margin. Shadow recovery and highlight detail retention were softer on the W620, sometimes forcing more aggressive exposure compensation.

In essence, if image quality - even within the confines of a small sensor - is paramount, Olympus’s more modern CMOS sensor endows it with a technical edge.

Screens and Interface: Clarity and User Experience in Composing Your Shot

A camera's LCD is more than a mere display; it’s the primary interaction portal and influences shooting confidence.

The SZ-30MR boasts a 3-inch fixed TFT HyperCrystal III LCD with 460k-dot resolution - bright, fairly crisp, and easy to read even in moderate sunlight (though glare remains a challenge). I found this screen particularly helpful reviewing focus fine-tuning in macro and telephoto shots.

The Sony W620 matches the fixed screen form factor but with a smaller 2.7-inch Clear Photo TFT LCD offering just 230k-dot resolution. It faithfully reproduces colors but feels cramped and less sharp when evaluating image details on site.

Neither camera provides touchscreen capability or an electronic viewfinder, limiting precise composition in bright outdoor scenarios. Users relying on LCD preview need to be mindful - particularly with the W620's smaller screen - in critical framing situations.

From an interface standpoint, both cameras prize simplicity: no manual focusing or exposure controls, and menus focused on point-and-shoot ease rather than customization. Olympus’s slightly more generous screen size and resolution, though, contribute to a subtly better handling experience.

Focal Length and Lens Versatility: The Vast Zoom Range Advantage

Here we can see the Olympus SZ-30MR assert one of its core advantages: lens reach.

• Olympus pairs its sensor with an impressive 25-600 mm equivalent zoom lens with a 24x range, aperture f/3.0-6.9.
• Sony W620 offers 28-140 mm (5x zoom), aperture f/3.2-6.5.

This difference in zoom factors defines their practical use cases. While the W620 comfortably covers everyday shooting from moderate wide-angle to short telephoto, the SZ-30MR ventures well into supertelephoto territory - vital for wildlife enthusiasts or remote sports photographers shooting from a distance.

The trade-off is that the SZ-30MR’s lens has a slower max aperture towards the telephoto end, which requires compensating through higher ISO or steadier hands/tripods. Nevertheless, built-in sensor-shift image stabilization on the Olympus helps counteract handshake for sharper shots at long zoom lengths - absent in the Sony W620.

Macro Performance: Close-Up Capacity and Focusing Precision

Macro photography remains an unfamiliar terrain for many point-and-shoot buyers, but here’s where the SZ-30MR shines thanks to its 1cm minimum focusing distance - allowing for detailed close-ups of small objects and textures.

Sony’s best macro focus range is about 5cm, which limits extreme close-ups but suffices for casual snapshots of flowers or insects.

The precision of Olympus’s AF system in macro mode impressed me, consistently hitting tight focus on tiny subjects, helped by contrast-detection AF and face detection to avoid misses. Sony’s system is slower and less confident in macro or low-contrast scenarios.

Autofocus and Burst Shooting: Speed and Accuracy in Action Photography

Neither camera targets fast-action photographers, but autofocus capabilities and burst shooting modes inevitably influence their versatility.

Both rely on contrast-detection autofocus, which, while accurate for static subjects, lacks the speed and predictive ability of phase-detect AF systems found in higher-end cameras.

Olympus offers face detection and a multi-area AF mode, supporting single AF with tracking (though no continuous AF or manual focus). Sony W620 includes face detection, center-weighted AF, and basic tracking, but lags slightly in responsiveness.

Burst rates put Olympus ahead with 2 fps continuous shooting versus Sony’s 1 fps, barely enough for casual sports but sufficient to capture fleeting moments.

Video Capabilities: Recording Quality and Usability

Video remains a secondary function for both cameras, but merits brief consideration.

The SZ-30MR records full HD at 1920 x 1080p, 30 fps, encoded in MPEG-4, delivering smooth motion and detailed imagery suited for casual video blogging or home movies.

Sony’s W620 caps out at 1280 x 720p, 30 fps, using the older Motion JPEG format, which consumes more storage and yields lower video quality, although still acceptable for basic web sharing.

Neither model supports external microphones, headphone jacks, or advanced video features like 4K or high-bitrate recording.

Connectivity and Storage: Expanding Your Shooting Ecosystem

Both cameras support Eye-Fi wireless-enabled memory cards, allowing Wi-Fi transfer of images, a welcome feature for on-the-go sharing before smartphones dominated this space. Neither camera has native Wi-Fi, Bluetooth, or NFC.

Storage-wise:

• Olympus and Sony both accept standard SD/SDHC/SDXC cards, with Sony adding compatibility for Memory Stick formats and microSD cards, offering more flexibility depending on card availability.

Physical connectivity is conventional: USB 2.0 for image transfer; Olympus uniquely adds an HDMI port for direct playback on external displays, absent on the Sony W620.

Battery Endurance and Practical Considerations

Both cameras promise around 220 shots per charge, which aligns with their compact, entry-level status.

Olympus uses the LI-50B battery, while Sony employs the NP-BN battery - both proprietary but common.

Given the Olympus’s heavier body and bigger zoom lens mechanism, I found its battery life held up well across sustained shooting sessions; the Sony’s smaller form generally resulted in shorter shooting bursts on a charge.
