Olympus E-420 vs Sony Cyber-shot DSC-W570: A Comprehensive Camera Showdown for Every Photographer

In the ever-evolving world of digital cameras, selecting gear that aligns with your photographic ambitions can be a challenge. Having personally tested thousands of cameras across genres and levels, I’m excited to delve into a detailed face-off between two distinctly different cameras: the Olympus E-420, a compact DSLR from 2008 targeting entry-level enthusiasts, and the Sony Cyber-shot DSC-W570, a slim ultracompact point-and-shoot from 2011 designed primarily for casual shooters. Despite being from different camera classes and eras, comparing these two offers unique insights into how design philosophies and technologies cater to photographer needs.

I’ll break down every vital aspect - from ergonomics and sensor tech to real-world performance across major photographic disciplines - with candid observations from hands-on use. Whether you are a beginner exploring DSLR potential or prefer a pocket-friendly camera for travel and street snaps, this comparison aims to clarify which camera suits your creative temperament best.

Holding the Cameras: Ergonomics and Handling

First impressions matter, and I always start my camera testing by feeling the body in hand - a crucial factor for long shoots. The Olympus E-420 positions itself as a compact DSLR with familiar SLR styling, while the Sony W570 is extremely pocketable.

Size and Handling

Check this out:

The Olympus E-420 measures approximately 130x91x53 mm, weighing around 426 grams. It’s compact for a DSLR but still offers the classic grip and control layout that DSLR users expect. When shooting portraits or landscapes, this size feels reassuringly solid. The pentamirror viewfinder, for all its budget nature, provides a true-to-life framing experience. The slightly heavier grip enables better stability in hand, especially when paired with Olympus’s range of lenses.

On the other hand, the Sony Cyber-shot W570 is a marvel of slim design - just 91x52x19 mm, weighing a mere 116 grams. It’s about as slim as a camera can get before compromising controls. The lack of a viewfinder nudges you towards LCD framing, and minimal physical buttons keep the body extremely lightweight and pocket-friendly. For street photography or travel where discretion and portability reign supreme, the W570 feels unbeatable. However, smaller grip real estate means less control in dynamic situations, especially for users accustomed to DSLRs.

Layout and Controls

A quick look from above reveals their different design philosophies:

The E-420 boasts a traditional DSLR’s mode dial, dedicated exposure compensation, and a decent selection of manual controls. This is a serious photographer’s tool allowing aperture and shutter priority modes, even full manual exposure. The Sony W570 is simplified, offering no shutter/aperture priority or manual modes. Instead, it relies mostly on automatic settings with limited exposure compensation options. The W570’s controls are minimalist - great for novices who want turn-on-and-shoot experiences but limiting for creative control.

Bottom line: The Olympus E-420 wins hands-down on ergonomics and tactile control for photographers who want an engaging manual shooting experience. The Sony excels if you want something affordable, simple, and pocket-friendly.

Under the Hood: Sensor Technology & Image Quality

Understanding this technical core is essential - you want to know what drives image quality in your camera.

Sensor Size and Resolution

Here’s a visual comparison:

The Olympus E-420 features a Four Thirds-sized CMOS sensor measuring 17.3x13 mm - significantly larger than the Sony W570’s 1/2.3” (6.17x4.55 mm) CCD sensor. This sensor size gap (about eight times larger surface area) translates directly into superior light-gathering capacity for the Olympus. It has a 10-megapixel resolution, capturing images at 3648x2736 pixels, while the Sony’s sensor is 16 megapixels (4608x3456 pixels).

You might think “more megapixels = better image,” but sensor size is more critical for image quality, especially in low light. The smaller sensor on the W570 generates more noise and less dynamic range despite higher pixel count, especially at higher ISOs.

Dynamic Range and ISO Performance

The Olympus’s sensor delivers around 10.4 stops dynamic range (DxOMark), enabling it to hold highlights and shadows better - crucial in landscape and high-contrast scenarios. Sony’s W570 sensor data isn’t officially tested by DxOMark, but users report relatively limited dynamic range and higher noise beyond ISO 400.

The max native ISO is 1600 on Olympus and 3200 on Sony. However, the W570’s small sensor struggles with manageable noise at ISOs above 400–800 in practice, limiting its usefulness for low-light shooting.

Autofocus Systems

• Olympus: 3 Phase/Contrast Detection AF points, with continuous AF and live view AF support. No face or eye detection.
• Sony: 9 contrast-detection points, no phase detection, no continuous AF.

The E-420’s hybrid AF system is better for tracking moving subjects, like in sports or wildlife, while the Sony’s slower contrast AF is suited for stills and simple scenes.

Viewing and Interface

Both cameras have similar 2.7" LCD screens at 230k resolution, fixed type (non-touch). The Sony offers a Clear Photo LCD which is a bit more vibrant outdoors. However:

Olympus has an optical pentamirror viewfinder covering 95% frame, useful in bright sun where LCDs struggle. The Sony lacks any viewfinder.

Versatility for Different Photography Genres

Now to the heart of your decision: how each camera performs in various genres I’ve tested extensively in real shoots.

Portrait Photography

Portraits demand skin tone fidelity, bokeh quality, and precise autofocus on eyes.

• Olympus E-420: The Four Thirds sensor renders pleasing skin tones with good color depth (21.5 bits DxO color depth rating). The E-420’s selectable AF points and manual lens control allow precise focusing on eyes even with fast Olympus Zuiko lenses providing smooth background blur. Lack of face detection is a downside but compensated by careful manual focus use. Built-in flash helps in fill light but can be harsh without diffuser.

• Sony W570: The W570’s small sensor limits tonal gradation; skin can appear smoother but less natural in strong light. The built-in zoom lens’s maximum aperture is f/2.6 (wide) to f/6.3 (tele), which limits background blur capability. Autofocus is contrast-only and single-shot, making fine eye focus tricky, especially indoors.

My takeaway: Olympus E-420 offers genuine portrait capabilities for enthusiasts willing to work manually. Sony is more a casual snapshot tool here.

Landscape Photography

Landscape demands high resolution, excellent dynamic range, and weather durability.

Olympus’s sensor and 10 MP resolution provide sharp, detailed files suitable for large prints. Its dynamic range excels at retaining highlight and shadow detail in bright skies and forested scenes. Lens ecosystem includes weather-spotted fast primes and wide zooms.

Sony’s higher 16 MP sensor resolution produces fine detail in daylight but struggles with highlight clipping and shadow noise. The lens (25-125mm equivalent) is versatile, but max aperture at tele end limits sharpness in low light dawn/dusk shoots.

Neither camera offers environmental sealing or rugged build - something to consider for outdoor enthusiasts.

Wildlife Photography

This genre depends on autofocus speed and burst rates.

The Olympus E-420’s continuous shooting at 4 fps combined with phase detection AF helps capture quick moments. Though limited to 3 AF points, the DSLR design allows use of telephoto Olympus lenses with decent reach and image stabilization in the lens.

The Sony W570 only shoots at 1 fps max and has slower, contrast-based AF - suboptimal for action. However, its 5x zoom (25-125mm equivalent) offers good reach for a compact.

Verdict: Olympus is the more capable wildlife tool, though by modern standards modest. Sony suits casual animal snaps.

Sports Photography

Key factors: tracking AF, frame rates, and low light capability.

Olympus’s 4 fps burst is workable for amateur sports. The 3-point AF tracking can lag on fast-moving subjects, and the modest ISO ceiling limits indoor performance.

Sony lacks burst mode and manual exposure options needed for sports shooting. Autofocus is single-shot only.

Olympus takes this category with reservations; Sony is outclassed due to hardware limits.

Street Photography

Street shooters prize discretion, low light performance, and portability.

Sony’s ultracompact size makes it invisible in crowds, a huge plus. Its lens starting at 25mm equivalent wide angle is great for street scenes. However, low light noise and slower AF reduce capture reliability.

Olympus, while compact for a DSLR, attracts attention more easily and its shutter sound is louder. But better image quality and manual control support more thoughtful street photography.

Macro Photography

Focusing precision and close focusing distance determine macro potential.

Sony W570 offers 5cm minimum focus distance, making it a straightforward option for casual close-ups.

Olympus’s system is limited by lens choice. Some Olympus Zuiko lenses offer macro capability, but the camera body itself lacks focus assist like focus peaking.

For serious macro, neither camera excels, but Olympus with dedicated macro lenses can outperform Sony’s fixed lens.

Night and Astrophotography

Requires high ISO performance and long exposure options.

Olympus max shutter speed is 1/4000s and minimum is 60 seconds with bulb mode unavailable. Manual exposure, native RAW support, and tripod use enable decent night shots with controlled noise due to bigger sensor.

Sony’s shutter maxes at 1/1600s, no manual modes, and no raw output, limiting post-processing latitude for astrophotography.

Olympus wins for long exposure creativity.

Video Capabilities

Sony offers HD video recording 1280x720 at 30 fps with MPEG-4 format, with optical stabilization helping smooth handheld footage.

Olympus E-420 lacks video recording outright.

If video is a priority, Sony W570 is clearly the better choice.

Travel Photography

For varied shooting conditions, battery life, and size matter.

Olympus’s heavier DSLR body, larger sensor, and extended battery life (~500 shots) give confidence on longer trips but add to bulk.

Sony’s ultracompact weight (116g) and slim profile shine in sightseeing and street walks, though battery life is in the low hundreds of shots.

The lens versatility of Olympus makes it more flexible, but Sony’s ease of carrying often wins travellers.

Professional Work Reliability

Though not a professional model, Olympus offers raw support, solid build, and lens interchangeability favored in pro workflows.

Sony’s fixed lens and no raw support exclude it from serious production use.

Build Quality and Weather Resistance

Neither camera offers weather sealing. Olympus’s DSLR construction feels robust with metal components; Sony is plastic with lesser toughness. Handle the E-420 with more confidence outdoors but bring care with both.

Connectivity and Storage

• Olympus uses Compact Flash and xD Picture Cards, common in 2008 but largely obsolete today.

• Sony W570 supports SD/SDHC/SDXC cards plus Memory Stick formats, more universal now.

Sony includes Eye-Fi wireless card compatibility; Olympus lacks wireless connectivity.

USB 2.0 is standard on both.

Battery and Power

Olympus uses proprietary battery pack lasting about 500 shots - respectable for DSLR.

Sony’s NP-BN1 battery specs aren’t clearly stated, but expect lower endurance given size.

Lens Ecosystem and Compatibility

Olympus Four Thirds mount offers access to over 45 lenses including fast primes, macro, wide angle, and telephoto. This is a decisive advantage when creative lens choices matter.

Sony W570 is fixed lens - 5x zoom from 25-125mm equivalent. Great for convenience, but no upgrades or specialized optics.
