Choosing Between the Sony W570 and Sony A37: A Hands-On, In-Depth Comparison from My Photography Experience

When it comes to picking a camera, the choices can feel like wandering into a jungle of acronyms and specs. Today, let’s cut through the marketing babble and get down to brass tacks by comparing two very different Sony offerings: the Sony Cyber-shot DSC-W570, a 2011 ultracompact digital camera, and the Sony SLT-A37, a 2012 entry-level DSLR-style camera featuring Sony’s then-novel translucent mirror technology.

Having tested thousands of cameras over the years - a lot hands-on in real-world conditions - I’m here to help you understand what these two shooters bring to the table and, importantly, which might fit your photography ambitions, style, and budget best.

Size Matters: Pocketable or Ready-to-Rumble?

First things first: size, weight, and ergonomics. Here is where the most obvious difference lies.

The Sony W570 weighs in at a featherlight 116 grams and fits into the palm with dimensions of roughly 91 x 52 x 19 mm - essentially pocketable, the definition of convenience for casual shooting or travel. The ultracompact body lacks an electronic viewfinder and sports a fixed lens, so you’re totin’ a simple point-and-shoot solution - no fuss, no muss.

Contrast that with the comparatively hefty 506 grams and a bulkier 124 x 92 x 85 mm footprint of the Sony A37. This camera’s chunky grip and removable lens mount hint loudly at more serious photographic intent. The A37 is a compact SLR-style camera, which means it feels like a proper tool in your hands, designed to be wielded with precision and some muscle.

If portability is king for you - say, street photography on the fly or travel where every gram counts - the W570 is a precious sidekick. But if you want a camera that grows with your skills and offers manual control and versatility, the A37 feels far more grown-up, albeit at the cost of pack space.

Design and Controls: Intuitive Simplicity vs. Functional Complexity

Beyond physical size, the tactile experience and control layout are paramount: do you want a camera that just works straight out of the box, or one that invites you to learn and tweak settings?

The W570 sports a minimalistic top layout, limited buttons, and a straightforward mode dial, targeting point-and-shoot convenience. This is a camera made for those who want to aim, shoot, and share - no settings menus or dials cluttering the experience.

The A37, on the other hand, packs the top with dedicated buttons for exposure modes, a mode dial, drive settings, and shutter/priorities - reflecting its advanced capabilities and aimed at photographers who enjoy customizing their shooting parameters. Those 15 autofocus points (including 3 cross-type) and a 6 fps continuous burst rate require a more accessible control scheme, which Sony delivers with this model.

For newcomers or casual shooters, the W570’s tactile simplicity might be less intimidating. Conversely, the A37’s richer set of controls invites experimentation and mastery, making it ideal for enthusiasts or pros dipping into mirrorless/DSLR worlds.

The Heart of the Camera: Sensor Technology and Image Quality

Arguably the most critical difference here is image quality potential, heavily influenced by sensor size, technology, and resolution.

The W570 uses a 1/2.3” CCD sensor measuring 6.17 x 4.55 mm (28.07 mm² area) with 16 megapixels, while the A37 boasts a much larger APS-C CMOS sensor (23.5 x 15.6 mm, 366.6 mm² area) also at 16 megapixels.

You’re probably already aware that sensor size impacts noise performance, depth of field control, and dynamic range. The A37’s sensor is roughly 13 times larger in surface area, enabling significantly better light gathering and cleaner images, particularly in low light. CMOS technology also allows faster readouts and video capabilities not achievable with a CCD sensor like the W570’s.

Laboratory tests report the A37’s DxO Mark overall score of 75 puts it in a decent league for entry-level DSLRs, with color depth of 23.3 bits, dynamic range at 12.9 EV, and low-light ISO performance solid up to ISO 799. The W570 hasn’t been benchmarked officially on DxO, but in my experience, its small sensor struggles beyond ISO 400, exhibiting considerable noise and limited dynamic range. Its maximum ISO is 3200, but usable quality bottoms out well below that.

Practically, landscape photographers will appreciate the A37’s ability to retain highlight and shadow details, while portrait shooters benefit from natural skin tones and more pleasing bokeh due to the larger sensor and interchangeable lenses.

Composing Your Shot: Displays and Viewfinders

Your ability to compose accurately and review images is strongly influenced by the camera’s screen and finder.

Both cameras feature a similar 2.6-2.7 inch LCD screen with low resolution (230k dots), but that’s about where their similarities end.

The W570’s fixed Clear Photo LCD is decent for its class but cramped and not very bright or contrast-rich. Since it lacks a viewfinder, you’re relegated almost solely to composing via the screen - fine in daylight, but tricky under intense sun or low light.

The A37 offers an electronic viewfinder (EVF) with 1,440-dot resolution and 100% coverage, plus a tilting LCD, allowing you to frame shots eye-level for stability or from creative angles. The EVF resolves better than typical optical finders in similar-class DSLRs and shows exposure previews in real time - a massive boon for manual exposure and nighttime shooting.

For anyone serious about framing precision and shooting in challenging light, the A37 dramatically outperforms. Casual users valuing simplicity might find the W570’s lack of viewfinder limiting.

Autofocus and Shooting Performance: Speed vs. Simplicity

Raw responsiveness can make or break action photography, and here the cameras part ways sharply.

The W570 relies on a contrast-detection AF system with 9 focus points and single-shot AF only - no continuous AF tracking or eye detection. It’s a one-shot wonder designed for casual scenes, not sports or wildlife. Full autofocus lag and occasional hunting under lower light plague this model.

Conversely, the A37 employs a 15-point phase-detection AF system using Sony’s translucent mirror technology. This means continuous autofocus during bursts up to 6 frames per second, perfect for tracking moving subjects such as athletes or animals. It also features face detection capabilities, assisting with accurate focus on people, a plus for portraitists.

During hands-on testing, the A37 proved decisively faster and more accurate in autofocus acquisition and maintenance compared to the W570’s plodding AF system.

Zoom and Lens Versatility: Fixed vs. Interchangeable

Lens choices define a camera’s flexibility.

The W570 is outfitted with a fixed 25-125mm equivalent zoom lens (5x), starting bright at f/2.6 but narrowing to f/6.3 at telephoto. This lens - while handy - cannot be swapped or upgraded. Macro shooters might appreciate a close focus range down to 5 cm, but beyond that, you're locked in. Image stabilization is optical, helping combat shake in telephoto shots.

Meanwhile, the A37 accepts any Sony A-mount lens - Sony’s incarnation of the Minolta Alpha system - with an extensive ecosystem of 143 lenses ranging from affordable primes to professional-grade telephoto zooms. This flexibility is a game-changer for creative growth. The camera also offers sensor-based image stabilization, which works with all attached lenses - a plus for telephoto or macro work where shake is more visible.

If you envision growing into diverse photography genres, investing in the A37’s lens ecosystem is the way to go. The W570’s fixed lens is simply too limiting for growing ambitions.

Shooting Genres and Real-World Application

Let’s pivot now into how each camera performs across photography styles - because specs only tell part of the story.

Portrait Photography

Skin tones and pleasing bokeh are king here, and lens control and sensor size are critical.

• W570: The small sensor and fixed lens produce images with less background separation and somewhat muted skin tones. Lack of autofocus face detection hurts ease of use. Bokeh is minimal due to narrow apertures.

• A37: Larger APS-C sensor, interchangeable lenses (prime or wide aperture zooms), and face detection AF mean portraits come out with creamy backgrounds and natural skin rendering. Manual exposure control offers artistic freedom.

Verdict: Serious portraiture demands the A37.

Landscape Photography

Here, dynamic range, resolution, and weather-sealing matter most.

• W570: No weather sealing, modest dynamic range, and limited control restrict landscape capability. Resolution is adequate for casual sharing.

• A37: Better dynamic range, manual exposure bracketing, and richer file formats (including RAW) enable post-processing flexibility essential for landscapes. However, no weather sealing means you’ll still need care in the elements.

Verdict: Go A37 for landscape enthusiasts.

Wildlife / Sports

Tracking speed, burst rates, and telephoto power determine success.

• W570: 1 fps burst rate and sluggish AF make capturing animals or sports tough.

• A37: 6 fps, phase-detection AF, and lens choice (telephotos) allow reasonably good coverage of fast-moving action in daylight.

Verdict: No contest - the A37 wins.

Street and Travel Photography

Compactness, discretion, and battery life come to the fore here.

• W570: Ultra compact and light, perfect for candid street shots where size and silence matter. Battery life not specified but typically less than DSLRs.

• A37: Larger and heavier but packs more versatility. 500-shot battery life is excellent for day-long travel sessions.

Verdict: W570 for lightweight travel; A37 if you want more control and better image quality.

Macro and Night/Astro Photography

Precise focus and high ISO capabilities matter here.

• W570: Close macro focus (5cm), but small sensor limits image quality and low light performance.

• A37: Sensor-based stabilization aids in handheld macro. High max ISO (25600) supports night and astro, though noise becomes visible at high settings. Tilting screen and EVF help framing tricky subjects.

Verdict: A37 offers strong advantages for macro and low light.

Video Capabilities: Casual Clips or Serious Clips?

Both cameras can shoot video, but specs differ markedly.

• W570 shoots HD at 1280 x 720 at 30fps in MPEG-4 format - basic, straightforward clips suitable for casual use.

• A37 supports full HD 1080p at up to 60fps in MPEG-4, AVCHD, and H.264, plus a microphone port for improved audio. This gives more cinematic flexibility and control.

For vloggers or videographers, the A37’s richer feature set and better sensor position it ahead.

Build Quality, Durability, and Battery

Neither has weather sealing or rugged build features like freezeproof or crushproof ratings. That said, the A37’s robust DSLR-inspired body feels solid and durable, designed for extended use - considerably more reassuring than the plastic-ultracompact W570.

The A37’s NP-FW50 battery rated at about 500 shots per charge comfortably beats typical compact camera runtimes - including the W570’s smaller NP-BN1 (unknown official rating but notably less capacity).

Connectivity and Extras

Both offer Eye-Fi card support for wireless photo transfers and HDMI output. Only the A37 sports a microphone jack for external audio recording during videos, a nod toward content creators.

Price-to-Performance: What Are You Really Paying For?

At the time of their release, the W570 retailed around $159, while the A37 commanded roughly $522.

Freely admitted: the W570 is a budget grabber for simple users who want a point-and-shoot with decent image quality in good light. The A37 sits squarely in the entry-level DSLR space, providing more serious capabilities and faster performance for enthusiasts prepared to invest in lenses.

Is the triple price tag justified? For those wanting improved image quality, manual controls, and future-proof versatility - absolutely.
