Olympus SP-820UZ vs Sony A35

Comparing the Olympus SP-820UZ and Sony A35: A Hands-On Dive into Superzoom and Entry-Level DSLR Worlds

Choosing a camera always pivots around your priorities: do you value sheer zoom reach and portability, or do you want DSLR-level image quality and manual controls? Today, we dig deep into two contenders from different corners - the Olympus Stylus SP-820UZ, a superzoom compact from 2012, and Sony’s 2011 entry-level translucent mirror DSLR, the A35. My experience testing thousands of cameras over the years will guide you through their features, performance, and real-world usability. Let’s separate the hype from the helpful, so you can confidently decide which fits your photographic ambitions.

First Impressions: Form Factor and Handling

At first glance, the Olympus SP-820UZ strikes you as a compact all-in-one designed for grab-and-go versatility. Its fixed lens and modest footprint (117 x 78 x 93 mm, 485 g) promise ease of carrying but at the expense of customization. The Sony A35 is a bulky little beast by comparison: a 124 x 92 x 85 mm body weighing 415 g, with DSLR styling and grip contours that hint at a more serious photographic experience.

Holding the two side by side, the Sony benefits from ergonomic familiarity for those used to DSLRs - a substantial grip, well-placed dials, and a thoughtful button layout. The Olympus's compact shape makes it pocketable in a pinch but sacrifices some control precision. Both include fixed rear screens, but the Sony's is noticeably crisper.

Sony’s top plate shows the DSLR DNA with dedicated exposure mode dials and a hot shoe for external flash, while Olympus keeps things minimalist - no manual exposure modes here. This difference reflects the A35’s appeal to enthusiasts craving creative control versus the SP-820UZ’s straightforward “point and shoot” philosophy.

Sensor Size and Image Quality: The Core Battle

Behind the lens is where the story diverges sharply:

The Olympus SP-820UZ houses a small 1/2.3-inch CMOS sensor with 14MP resolution, typical for superzoom compacts. Small sensors struggle with noise at higher ISOs and have limited dynamic range, especially in challenging lighting. It’s a sensor optimized for convenience and reach - the zoom lens stretches an impressive 40x from 22 mm equivalent wide to an astonishing 896 mm telephoto.

Contrast that with the Sony A35’s 16MP APS-C sized CMOS sensor (23.5 x 15.6 mm), roughly 13 times the surface area of Olympus’s chip. This larger sensor offers much better low-light performance, richer color depth, and remarkable detail retention. The Sony additionally supports RAW shooting, enabling extensive post-processing control - a critical factor for professionals and enthusiasts.

In practical terms, the Olympus excels in daylight scenarios where the zoom diversity is king: wildlife glimpses from afar, casual travel snapshots, or family events. But shadow detail and noise control at ISO 800+ feel decidedly limited.

The A35, on the other hand, showcases superior clarity, tonal richness, and shadow recovery - attributes highly valued in portrait, landscape, and low-light shooting. Its APS-C sensor is more forgiving, retaining usable ISO up to 3200 and beyond with acceptable noise levels.

User Interface and Display: Your Window to Creativity

Both cameras feature 3-inch rear LCDs, but size isn’t the only metric that matters.

The Olympus SP-820UZ’s 460k-dot TFT screen is serviceable but feels dim under bright sunlight, and its fixed non-touch design limits intuitive control. It offers live view but no touchscreen capability, which, for a 2012 budget superzoom, isn’t surprising.

Sony’s A35 steps it up with a 921k-dot screen providing sharper detail and better viewing angles. Coupled with its electronic viewfinder (EVF) boasting 1.15M-dot resolution and 100% frame coverage, composing shots in varying light becomes easier and more precise. The EVF is a standout for those migrating from optical viewfinders: it gives real-time exposure previews, white balance effects, and focus peaking - features missing on the Olympus.

User interface-wise, Sony’s menus expose full manual exposure modes, custom white balance, bracketing options, and autofocus customization. Olympus keeps things simplified, focusing on casual shooting modes without aperture or shutter priority or manual exposure.

Autofocus and Burst Performance: Speed in Capture

Autofocus is fundamental across all genres, so how do these two fare in action?

The Olympus SP-820UZ employs a contrast-detection system with face detection. Unfortunately, it’s sluggish and prone to hunting in low contrast or dim conditions. No continuous AF, no tracking - it locks focus in single AF mode only. Its continuous shooting caps at 2 fps, enough for casual snapshots but insufficient for sports or wildlife photographers needing rapid sequences.

Sony’s A35 leverages a hybrid autofocus system combining phase detection and contrast detection with 15 AF points (3 cross-type). This setup delivers significantly faster and more accurate focusing, especially when tracking moving subjects. Although it lacks advanced animal eye AF or face tracking found in newer models, it remains competent for action and portraiture.

Burst shooting maxes at about 6 fps, suitable for moderate sports shooting, and capture buffer handling is well managed thanks to its faster processor. For me, this difference is night and day: the A35 feels alive and responsive, while the Olympus seems static and hesitant.

Optical Versatility and Lens Ecosystem

Let’s dissect lenses - a key to your creative vision.

The Olympus SP-820UZ’s defining feature is its massive 40x zoom lens with focal lengths from 22 to 896 mm equivalent, covering ultra-wide to super-telephoto. While impressive on paper and in travel snapshots, the maximum aperture ranges from f/3.4 wide-angle to f/5.7 telephoto, typical of compact superzooms, resulting in soft corners wide open and limited background blur.

Also, the lens is fixed - no swapping or upgrades - so you’re locked into this optical path.

The Sony A35’s body opens the door to the Sony A-mount lens ecosystem with more than 140 native lenses ranging from ultra-wide to specialty optics - primes, macros, telephoto zooms, and fast apertures. This extensiveness turns the A35 into a versatile tool adaptable to all genres I’ve tested, from landscapes requiring sharp wide angles to portraits needing creamy bokeh.

Sony also benefits from sensor-based image stabilization, which works with all lenses, including older manual focus glass, enhancing low-light and macro capabilities.

Image Stabilization and Macro Capabilities

Regarding shake correction, Olympus’s SP-820UZ disappoints: no optical or sensor-shift stabilization technology is present, which is unusual for a superzoom but likely a cost-saving decision. Telephoto hand-shake is a real nuisance, and you’ll need a tripod or very high ISOs indoors.

Conversely, the Sony A35 employs sensor-based stabilization that works hand-in-hand with any attached lens. The amplitude isn’t as strong as the best in-lens IS, but it reliably assists macro shots and handheld video and is notably beneficial indoors or in low light.

In terms of macro, the Olympus lens achieves focusing down to 1 cm, allowing fun close-ups in conveniently designed superzoom style. The Sony’s macro ability depends on the lens chosen, but dedicated macro primes or zoom macros outperform the Olympus’s fixed lens in resolution and focusing precision.

Flash and External Lighting

Both cameras include built-in flashes. Olympus’s built-in flash has an effective range up to 15 m, respectable for a compact. However, it has limited modes and no external flash support, restricting creative flash photography.

The Sony A35’s pop-up flash supports wireless TTL and high-speed sync when paired with compatible external flashes. This creates a powerful lighting toolbox for portrait and event shooters, lending flexibility and refined control over lighting quality.

Video Functionality: Recording Capabilities

Videographers will want to weigh video specs closely.

Both cameras can shoot Full HD video at 1920 x 1080 resolution, but their frame rate and codec support differ.

Olympus records 1080p at 30 fps using MPEG-4/H.264, with slower frame rates for lower resolutions (and some interesting “high-speed” 120 fps VGA clips which can be fun for slow motion).

Sony’s A35 films full HD at up to 60 fps with AVCHD support - preferred for higher quality recording and smooth motion. It also offers microphone input for external audio, a boon for serious videographers, while Olympus lacks any microphone or headphone jacks.

Neither camera offers 4K or advanced video features seen in modern mirrorless or DSLR hybrids, unsurprisingly given their release years.

Battery Life and Storage

The Olympus SP-820UZ’s battery life is unspecified in official specs, but field testing finds it limited - around 200 shots per charge, reflecting its compact design and power constraints.

Sony A35’s NP-FW50 battery delivers a solid 440 shots per charge (CIPA rating), quite respectable for an APS-C DSLR-style camera with an EVF.

Both cameras support SD and SDHC cards, but Sony expands compatibility to Memory Stick Pro Duo/Pro-HG Duo cards as well.

Connectivity, Weather Sealing, and Built-In Features

Neither the Olympus SP-820UZ nor Sony A35 includes wireless features such as Wi-Fi, NFC, or Bluetooth, which now feel standard but were less common when these models launched.

Both lack environmental sealing, dustproofing, or waterproofing, so cautious handling outdoors is advised.

Unique to Olympus is a “pet auto shutter” self-timer mode, aiming to capture dogs or cats at the right moment - a fun, quirky bonus for family photographers.

Real-World Shooting Scenarios: Matching Cameras to Genres

Understanding how these specs translate into photography disciplines will help spot your fit.

Portrait Photography

Portraiture thrives on skin tone rendition, shallow depth of field, and sharp critical focus - especially eye detection. The Sony A35’s larger sensor and interchangeable fast lenses (like 50mm f/1.8) handily outperform Olympus’s superzoom. The A35 can render creamy bokeh backgrounds and accurately lock focus on faces, thanks to its 15-point phase-detect AF and face detection.

The Olympus SP-820UZ, with slower lenses and a small sensor, offers less subject separation and softer image quality. It’s suitable for casual snapshots but unlikely to satisfy serious portrait shoots.

Landscape Photography

Landscape demands high resolution, wide-angle optics, dynamic range, and weather tolerance. Sony’s APS-C sensor gives the A35 a clear advantage in image quality and dynamic range, capturing more details in shadows and highlights.

Olympus’s ultra-wide to super-tele zoom lens affords framing flexibility but struggles with edge sharpness and noise in shadows. Neither camera is weather sealed, so using rain covers or shelters is advisable.

Wildlife and Sports Photography

For fast action, autofocus speed and burst rate are critical. Sony’s 6 fps continuous shooting with reliable phase detection AF edges ahead of the Olympus’s slow 2 fps contrast AF.

Long telephoto reach is Olympus’s trump card here - 896 mm equivalent focal length is massive, letting you capture distant subjects without costly tele lenses. However, poor stabilization and slow AF might result in missed shots.

The A35, with faster glass and versatile lenses, plus superior AF tracking, achieves better keeper rates on moving subjects but requires investment in quality telephoto lenses.

Street and Travel Photography

The Olympus, with its compact body and massive zoom, excels in versatility for travel photography - no lens changes, and you can frame everything from wide street scapes to distant landmarks. Battery life and limited controls restrict it to casual shooting though.

The Sony A35 is larger and heavier, with the necessity of carrying lenses, but rewards with better image quality and creative control. Its longer battery life is a plus on trips.

For street photography, Olympus’s zoomed reach might be less practical due to slower AF and size; Sony’s stealth approach is less feasible as well, given DSLR form factor.

Macro and Close-Up Photography

Olympus has fixed lens macro focusing to 1 cm, providing decent close-ups for casual use.

Sony’s macro efficacy depends on lens choice but benefits from its steady sensor stabilization and superior focusing systems for sharp detail. The flexible lens ecosystem provides more serious macro options.

Night and Astrophotography

Low-light performance heavily favors the Sony A35, with cleaner high ISO output and longer shutter speeds supported by modes. Olympus’s sensor noise and limited ISO capabilities hinder night shots.

Neither model offers in-body exposure stacking or intervalometer functions necessary for advanced astro work.

Video Production

Sony’s better video specs, higher bitrates, microphone input, and 60 fps Full HD shooting make it more appealing for casual video creators.

Olympus is more limited and strictly entry-level video.

Professional and Workflow Considerations

Sony supports RAW capture, offering photographers full flexibility during post-processing workflows. The Olympus cannot shoot RAW, locking you into compressed JPEG files.

Sony’s compatibility with professional-grade lenses and lighting gear makes it a tool capable of semi-professional work, while Olympus remains a consumer-focused snapshot camera.

Performance Summary and Scores

Let’s distill the data:

The Sony A35 scores significantly higher on image quality, autofocus, burst shooting, and video capabilities. Olympus only shines with its zoom reach and portability.

Photography-specific strengths align: Olympus leads travel flexibility but lags behind fundamentally in image quality and speed.
