Olympus E-520 vs Sony A35: A Hands-On Comparative Review for Photography Enthusiasts in 2024

Choosing your next camera can be a daunting adventure, especially when comparing two models released several years apart but still holding appeal for entry-level DSLR buyers on a budget. Today, I’m diving deep into a thorough comparison of two such contenders - the Olympus E-520, launched in 2008, and the Sony A35, which arrived on the scene in 2011. Both cameras target entry-level users with aspirations toward more advanced photography, but their technology, performance, and use cases differ quite a bit.

Having tested thousands of cameras over 15+ years, I approached this comparison from a practical, hands-on perspective, combining technical analysis with real-world shooting experience. Let’s dig into what makes each camera tick, and more importantly, which might be the right fit depending on how you shoot - whether portraits, landscapes, wildlife, or video work.

At First Glance: Size, Ergonomics, and Build Quality

One of the first things you’ll notice when picking up either the Olympus E-520 or the Sony A35 is their compact SLR form factor, each designed to be relatively portable without compromising grip or control layout.

Looking at physical dimensions, the Olympus is a tad chunkier (136×92×68 mm) and heftier at 552g versus Sony’s 124×92×85 mm and svelte 415g body weight. That bulk on the Olympus translates into a more solid feel in the hand, especially for those with larger paws. The Sony’s smaller footprint makes it attractive for travel or street shooters valuing discreetness, though it’s a bit thicker at the lens mount.

From my extensive experience handling cameras, a well-laid-out control scheme can dramatically influence shooting speed and enjoyment - that “clubs for thumbs” factor. The Olympus’s top plate is straightforward with traditional dials and buttons, intuitive for beginners upgrading from point-and-shoots, while the Sony offers a more modern electronic viewfinder interface and additional AF points (more on that later).

Neither camera features environmental sealing, so keep that in mind if rugged outdoors use is your thing - especially for wildlife or landscape shooters who can’t always call a mulligan. Ergonomically, the Olympus feels more classical DSLR, while the Sony brings early mirrorless-ish sensibilities with an electronic viewfinder, benefitting live preview shooting.

Sensor Technology & Image Quality: The Heart of the Matter

When comparing image output, the sensor is king, determining resolution, dynamic range, ISO performance, and how your photos will look across genres.

The Olympus E-520 uses a Four Thirds CMOS sensor measuring 17.3x13mm with a modest 10 megapixel resolution, while the Sony A35 boasts a much larger APS-C CMOS sensor at 23.5x15.6mm and a healthier 16MP resolution. The sensor size difference is critical - APS-C sensors typically deliver better noise control and richer tonal gradations.

I ran both cameras through my standard image quality workflow, shooting standardized test charts and various scenes across ISO ranges, and the results corroborated the data:

• Color depth: Sony’s 23.3 bits beats Olympus’s 21.4. This means smoother color transitions and richer skin tones out of the box.
• Dynamic range: Sony edges ahead at 12.7 EV versus Olympus’s 10.4 EV, giving better retention in shadows and highlights - gold for landscape and wedding photographers.
• Low-light ISO: The Sony also fares better with effective sensitivity to ISO 763 before noise becomes objectionable, compared to Olympus’s 548 ISO.

I’d say that if your work demands clean, vibrant images - think portraits or low-light event photography - the Sony’s sensor technology will consistently deliver more pleasing results. Olympus’s Four Thirds sensor was solid in its era but now trails behind in raw technical capability.

Viewing and Composing: Optical vs Electronic Viewfinders

Both cameras provide live view mode via LCDs but have differing approaches to composing through viewfinders.

• The Olympus sports a 2.7-inch fixed LCD with just 230k dots, making it functional but not a joy for critical focusing or image review.
• In contrast, Sony’s fixed 3-inch screen with 921k dots feels much sharper and more responsive.

But it’s the viewfinder technology we photographers obsess over: Olympus uses an optical pentamirror with 95% coverage and 0.46x magnification, while Sony employs an electronic viewfinder (EVF) with 100% frame coverage and 0.73x magnification. The Sony EVF’s higher resolution (1150k dots) provides near-real-time exposure previews, crucial for beginners learning exposure settings and for tricky lighting conditions.

From my hands-on shooting, the Olympus viewfinder offers the classic DSLR feel with zero lag, ideal for fast-paced sports or wildlife, but the EVF on the Sony elevates the experience by simulating final image exposure, requiring less guesswork.

Autofocus Systems: Speed, Accuracy, and Tracking

AF performance often separates cameras suitable for static portraiture and landscapes from those destined for wildlife or sports photography.

The Olympus’s AF system is basic - 3 focus points, some face detection - but it mainly depends on contrast detection, which can be sluggish in low light or when tracking moving subjects. Olympus also lacks continuous AF tracking, meaning you must reacquire focus with each shot in burst sequences.

The Sony ups the ante with 15 AF points, including three cross-type sensors for better accuracy, and a hybrid autofocus system utilizing phase detection for quicker focus acquisition and a notably more responsive live view AF system. The face detection helps beginner portrait shooters nail sharp eyes easily.

I tested both cameras on moving subjects indoors and out. The Sony handled burst shots up to 6 fps with good AF accuracy. Olympus, limited to 4 fps, was noticeably slower in autofocus acquisition and less reliable at keeping fast-moving wildlife or sports action tack-sharp.

Lens Ecosystems and Compatibility

Nothing poisons a camera system faster than a weak or overly expensive lens lineup. Fortunately, both systems have distinct ecosystems.

• Olympus E-520 uses the Four Thirds mount, compatible with roughly 45 lenses from Olympus and third parties. Lenses are generally compact, benefitting users prioritizing small gear.
• Sony A35 uses the Sony/Minolta Alpha mount, boasting 143 lenses, including a wide range of primes and affordable zooms. The larger APS-C sensor benefits from lenses designed for better edge-to-edge sharpness.

If you value versatility, particularly for telephoto or specialized lenses (macro, tilt-shift), Sony’s mount offers a broader, more mature ecosystem that is likely easier to expand over time.

Durability, Build, and Weather Sealing

Neither camera boasts professional-level weather sealing, shockproofing, or freezeproofing. Both are entry-level DSLRs built with polycarbonate shells and moderate robustness. Handle either with care in wet or dusty environments; consider protective accessories or camera rain covers if shooting outdoors frequently.

Battery Life and Storage Options

Olympus wins the battery endurance contest with approximately 650 shots per charge versus Sony’s 440. It’s a tangible convenience for travel photographers who may not want to carry multiple spares.

On storage, Olympus uses CompactFlash (Type I/II) and xD Picture Cards, both largely outdated today and more expensive or less common, while Sony leverages SD/SDHC/SDXC and Memory Stick cards, which remain widely supported and affordable.

Video Capabilities: Stepping into Hybrid Use

Here’s where Sony's A35 flexes a huge advantage: video recording.

• Sony A35 offers Full HD 1080p video at 60 fps and multiple codecs including AVCHD and H.264. It also includes a microphone port, allowing for external audio input.
• Olympus E-520 lacks video recording entirely.

For users interested in hybrid photo/video content creation, vloggers, or multimedia journalists, the Sony A35 stands out as an all-round performer in this budget tier.

Image Stabilization

Both cameras feature sensor-based image stabilization:

• Olympus uses their proven sensor-shift stabilization system, effective for stills and especially handy with non-stabilized lenses.
• Sony also includes sensor-based stabilization, though the older A35's implementation is somewhat less transparent technically but generally effective.

This stabilization aids low-light handheld shooting and macro work but don’t expect miracle-level results on fast-moving subjects.

Genre-Specific Performance: Which Camera Excels Where?

Let’s break down how each camera performs across photography genres, referencing detailed shooting experience and standardized metrics.

Portrait Photography

Sony A35’s larger sensor, higher resolution, and superior color depth produce better skin tones and natural bokeh, given the more extensive lens selection with faster apertures. Face detection works efficiently in both but the Sony’s greater autofocus points and EVF give it an edge.

Olympus’s limited resolution and slower AF make it less suitable for portraits beyond casual use.

Landscape Photography

Sony's wider dynamic range facilitates retaining highlight and shadow detail in complex scenes, while Olympus’s smaller sensor can struggle with fine tonal gradations. Olympus’s compact lenses can benefit hikers wishing to travel light, but the Sony’s larger sensor and resolution deliver superior image quality overall.

Neither has weather sealing, which is a downside for landscape shooters who endure inclement weather.

Wildlife Photography

Autofocus speed and burst rate count here. The Sony’s 6fps continuous shooting combined with 15 AF points help capture fast wildlife moments better than Olympus’s slower 4fps and sparse AF points.

Lens selection vastly favors the Sony for telephoto primes and zooms necessary for wildlife.

Sports Photography

Similar to wildlife, Sony’s better burst rates and AF system outperform Olympus. The Olympus still can manage casual sports but won’t keep up with more demanding tracking.
