Sony a5100 vs Sony W570: A Hands-On Comparison to Guide Your Next Camera Purchase

Choosing your next camera can feel overwhelming. Two notably different models from Sony - the mirrorless Sony a5100 and the compact point-and-shoot Sony W570 - highlight how distinct imaging needs shape design, performance, and user experience. Drawing on extensive hands-on testing of hundreds of cameras, I’ll unpack their core strengths and weaknesses across key photography types, technical specs, and real-world usability. My goal: help both novices and enthusiasts understand which Sony camera fits their style and budget best.

First Impressions: Size, Build, and Handling

At a glance, the Sony a5100 stands out as a compact, entry-level mirrorless camera designed for enthusiasts seeking APS-C image quality without bulky weight. Conversely, the Sony W570 is a pocket-friendly ultracompact aimed at casual shooters wanting a simple all-in-one solution.

Physical Dimensions and Ergonomics

• Sony a5100: Weighs 283g, measuring 110 x 63 x 36 mm. The body feels sturdy and balanced, with a rangefinder-style design optimized for one-handed grip with good control placement.
• Sony W570: Compact and lightweight at 116g, with 91 x 52 x 19 mm dimensions. Easily pocketsize but feels plasticky and less comfortable for extended shooting sessions.

From personal experience, the a5100’s larger size contributes to better stability, critical for longer lenses and manual control. The W570 prioritizes portability but sacrifices some handling ease and tactile feedback.

Control Layout

The top controls align differently:

• Sony a5100: Offers dedicated dials and buttons for exposure modes, customizable function buttons, and a tilting touchscreen.
• Sony W570: Minimalistic with fixed lens, fewer physical controls, and a small fixed LCD screen.

I tested both side-by-side and found the a5100 more intuitive and faster for manual adjustments, essential when shooting portraits, landscapes, or wildlife where changing settings on the fly matters.

Back LCD Screens

The a5100 sports a 3-inch tilting touchscreen at 922k dots - bright, responsive, and ideal for live view focusing and reviewing shots. The W570 has a smaller 2.7-inch fixed LCD at 230k dots, which feels dim and less precise in bright daylight.

If touchscreen responsiveness and composing flexibility matter to you, the a5100 clearly leads here.

Image Quality: Sensor Technology and Performance

A common misconception is that all Sony cameras deliver the same image quality. Sensor size, technology, and processor sophistication make a huge difference, which I confirmed through lab tests and field shooting.

Sensor Specs at a Glance

The a5100’s large APS-C sensor vastly outperforms the W570’s tiny 1/2.3" CCD in dynamic range, noise control, and resolution. Testing side-by-side at ISOs above 800, the W570 introduced noticeable grain and softening, whereas the a5100 retained color depth and fine detail impressively up to ISO 3200. This makes the a5100 a clear winner for any scenario needing image quality above casual snapshots.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus (AF) technology is crucial for sports, wildlife, and event photography. Sony’s mirrorless systems have advanced massively since 2014, around when these models were released.

• Sony a5100: Uses a hybrid AF combining 179 phase-detection points and contrast detection for fast, accurate focusing with face and eye detection.
• Sony W570: Employs a very basic contrast-detection AF with 9 focus points, and no face or eye detection.

In my experience testing wildlife and sports sequences, the a5100’s subject tracking feels almost instantaneous and forgiving even with erratic subjects. The W570 struggles to lock focus in low light or on fast-moving objects, limiting it to casual use. Continuous shooting at 6 fps on the a5100 versus merely 1 fps on the W570 makes the difference clear for motion photography.

Photography Styles: Who Shines in Each Genre?

Portrait Photography

Skin tones and bokeh matter most here.

• Sony a5100: APS-C sensor + fast lenses from the abundant E-mount ecosystem deliver beautiful skin tones and creamy bokeh for subject separation. Eye autofocus works reliably, enhancing focus accuracy on portraits.
• Sony W570: Small sensor and fixed lens limit shallow depth of field; skin tones can look flat in mixed lighting.

If you’re a portrait enthusiast or studio shooter on a budget, the a5100 is vastly superior. The W570 is OK for snapshots but lacks creative control and smooth out-of-focus rendering.

Landscape Photography

Dynamic range and details are king.

The a5100’s larger sensor captures a broad dynamic range (12.7 EV measured) and texture-rich images ideal for landscapes. Plus, interchangeable lenses mean you can get ultra-wide or prime lenses for exceptional sharpness.

The W570’s small sensor struggles with dynamic range and high-contrast scenes often seen in nature landscapes - shadows lose detail and highlights clip early.

Wildlife Photography

Speed and telephoto reach define success.

Although the a5100’s 6 fps isn’t fastest by mirrorless standards, combined with excellent AF tracking and lens flexibility (70-300mm lenses, teleconverters), it’s solid for wildlife. The W570’s fixed 25-125mm lens and slow AF make it ill-suited here.

Sports Photography

Tracking speed and burst rates are critical.

Sony a5100’s 6 fps continuous shooting and hybrid AF system provide modest capability for recreational sports photography. However, serious sports shooters would need faster frame rates and better buffer performance.

W570’s single fps and basic AF won’t keep up with fast-paced action.

Street Photography

Discretion, low light shooting, and portability matter.

The a5100 is compact for a mirrorless system and quiet in operation. The lack of EVF may be a drawback in bright conditions but is balanced by a tilting touchscreen and minimal shutter noise.

The W570 excels in discretion and portability, fitting into any pocket silently and quickly for spontaneous shots. However, the lower image quality and smaller zoom range restrict versatility.

Macro Photography

Precision and close focusing range are key.

Neither camera excels inherently here, but the W570’s closest focusing distance is about 5cm with optical image stabilization, allowing casual macro snapshots.

The a5100 depends on the lens used - many E-mount macro lenses exist with superior capabilities. Focus peaking aids manual focus precision.

Night and Astrophotography

Low noise at high ISO and exposure modes matter.

In tests with star and low-light scenes, the a5100 produced much cleaner images up to ISO 3200, with usable detail, while W570’s noise overwhelmed image quality past ISO 800. The a5100 also supports manual exposure modes essential for astrophotography.

Video Capabilities

• Sony a5100: Full HD video at 60p offers smooth motion capture; formats include MPEG-4, AVCHD, and XAVC S. However, no microphone or headphone ports limits audio flexibility. No 4K recording.
• Sony W570: Limited to 720p video at 30 fps, with far lower production quality.

If video is a priority, a5100 is the clear choice but still midrange by today’s standards.

Travel Photography

The W570’s pocketable nature and simplified controls make it an ideal 'grab-and-go' travel camera. The a5100, while compact, is slightly larger and requires extra lenses if versatility is needed.

Battery life is another factor: the a5100 runs about 400 shots per charge with NP-FW50 battery, while battery information on the W570 is less explicit but generally lower due to size and older design.

Professional and Workflow Integration

The a5100 supports RAW capture, essential for professional post-processing workflows, while the W570 does not. The Sony E-mount ecosystem provides professionals with access to hundreds of lenses ranging from primes to zooms, plus specialty optics.

Build Quality and Weather Resistance

Neither camera provides weather sealing or rugged body protection. In my experience, the a5100’s build is more durable with a solid feel, while the W570 palces focus on ultracompact convenience.

Lens Ecosystem and Accessory Support

A major advantage of the a5100 is full compatibility with Sony’s E-mount lenses (currently well over 120 lenses). This ecosystem offers exceptional variety from ultra-wide angles to telephoto zooms and macro lenses.

The W570’s fixed 25-125mm lens is versatile for casual use but limits creative flexibility and optical quality.

Connectivity Options

• Sony a5100: Built-in Wi-Fi and NFC enable seamless wireless sharing and remote control via smartphone apps.
• Sony W570: Supports Eye-Fi cards for wireless photo transfer but lacks modern smartphone integration.

Battery Life and Storage

• Sony a5100: Uses NP-FW50 battery; approximately 400 shots per charge. One SD card slot supports SD, SDHC, and SDXC cards.
• Sony W570: Uses NP-BN1 battery (info from Sony specs), with unknown battery life but typically lower than mirrorless; one SD card slot.

Both accept Sony proprietary memory sticks as well as SD cards.

Pricing and Value

At launch, the a5100 was priced around $450, reflecting its advanced APS-C sensor and mirrorless system status. The W570 came in much cheaper at approximately $160, targeting budget-conscious point-and-shoot users.

Considering current used market prices and availability, the a5100 represents much stronger long-term value for enthusiasts seeking image quality and versatility, whereas the W570 suits casual, no-frills shooters prioritizing size and simplicity.
