Sony NEX-3N vs Sony DSC-W510: A Hands-On Comparison for Photographers in 2024

Choosing the right camera often means balancing features, image quality, ergonomics, and budget. Today, I’m diving deep into two distinctive Sony models that at first glance belong to different categories: the Sony Alpha NEX-3N, an entry-level mirrorless camera announced in 2013, and the Sony Cyber-shot DSC-W510, a compact point-and-shoot announced in 2011. With over 15 years of camera testing under my belt, I’ve put these cameras through their paces - evaluating everything from sensor performance to handling, autofocus capabilities, and video features. This detailed comparison will give you an expert perspective rooted in real-world use, helping you decide which might best serve your photography goals.

Designing for Different Users: Size, Ergonomics, and Build

The first clear distinction is physical design and intended usage. The Sony NEX-3N adopts a rangefinder-style mirrorless form, whereas the Sony W510 is an ultra-compact fixed-lens camera aimed at casual point-and-shoot users.

• Sony NEX-3N measures 110 x 62 x 35 mm and weighs 269 grams - compact for a mirrorless but noticeably larger and heavier than most compacts. It features a robust rangefinder-style grip and a handful of external controls that encourage manual adjustments.

• Sony DSC-W510 is tiny: 96 x 54 x 20 mm and just 119 grams. With its palm-friendly ultra-compact body, it’s perfect for slipping in a pocket or purse and quick grab-and-go shooting.

Comparing these directly, the NEX-3N’s larger body provides significantly better ergonomics, a more substantial grip, and buttons that are comfortable to use for extended shooting. In contrast, the W510’s slimness favors ultimate portability at the expense of manual control and handling comfort.

If you prioritize a camera you can truly hold and control - especially when shooting outdoors or on the move - the NEX-3N’s design wins hands down. Conversely, the W510 caters perfectly to those who want a no-fuss, ultra-light camera for casual snapshots.

Sensor and Image Quality: The Heart of the Camera

Sensor technology drives image quality more than anything else. Here the differences are wide and consequential.

• The Sony NEX-3N sports a 16MP APS-C CMOS sensor measuring 23.5 x 15.6 mm providing a sensor area of roughly 367 mm² - remarkably large compared to many consumer cameras. APS-C sensors are renowned for superior image quality, especially in low light, delivering better noise control, dynamic range, and color depth.

• The Sony W510 carries a tiny 1/2.3-inch CCD sensor (6.17 x 4.55 mm), with a 12MP resolution and a sensor area of about 28 mm². This sensor size is typical for compact cameras, but it inherently limits image quality, especially in challenging lighting.

Measured by DxOMark scores (where available), the NEX-3N ranks with color depth of 22.8 bits and dynamic range of 12.5 EV, reflecting its strong image quality pedigree. The W510 hasn’t been tested by DxOMark, but the limitations of a small 1/2.3-inch sensor and CCD technology - especially in noise control and dynamic range - are well understood.

In practice, I found the NEX-3N images exhibit cleaner shadows, smoother tonal gradations, and richer colors, especially when shooting RAW. It handles higher ISO settings far better (native ISO up to 16000 vs. 3200 in the W510), making it far more flexible for low light, indoor, or night photography.

In summary, if image quality, especially in varied lighting, is your priority, the NEX-3N’s APS-C sensor is a crucial advantage. The W510’s compact size sensor limits you to bright conditions and short-range scenes.

Seeing the Scene: Display and Viewfinder Experience

Neither camera has a traditional electronic viewfinder. Instead, both rely on LCD screens of different sizes and resolutions:

• The NEX-3N has a 3" tilting LCD with 460k-dot resolution. The tilting mechanism is immensely helpful for creative angles, high or low shots, and some awkward compositions.

• The W510 sports a fixed 2.7" screen with 230k-dot resolution, using Sony’s Clear Photo LCD technology to boost visibility.

From my tests, the NEX-3N screen is noticeably sharper, larger, and more versatile for framing. Tilting screens like the NEX-3N’s are a real blessing in practice - whether shooting street scenes from waist height or overhead landscapes.

The W510’s smaller, fixed screen restricts flexibility, which can occasionally make framing tricky and tiring, especially under bright daylight.

Autofocus, Manual Controls, and Shooting Responsiveness

Here the two cameras diverge again in capabilities and speed.

• The Sony NEX-3N uses a 25-point contrast-detection autofocus system with selective and continuous options. It lacks phase detection, common in more advanced models, but for an entry-level mirrorless, its AF is respectable and fairly quick in good light. The camera supports Aperture, Shutter, and Manual exposure modes, giving you creative control. Unfortunately, there's no eye-detection AF or animal eye AF; this is expected in this generation/model.

• The Sony W510 uses 9 contrast-detection points with single AF only and slower focus acquisition. It offers no manual focus, no manual exposure modes, and no tracking AF.

In real-world shooting, the NEX-3N is snappier and significantly more versatile for action or changing scenes. The W510 is fine for casual photos but quickly frustrating for anything beyond simple snapshots.

The NEX-3N offers a modest continuous shooting speed of 4 fps, beneficial for moderate action or family events. The W510 shoots at just 1 fps, reflecting its casual point-and-shoot nature.

My hands-on testing clearly showed the NEX-3N’s autofocus felt more reliable and responsive, especially in challenging lighting. The W510’s AF lag and single mode limit its scope to static subjects in well-lit conditions.

Lens Ecosystem: One Lens or Many?

Which lens system you choose profoundly shapes what you can do with your camera.

• The Sony NEX-3N accepts Sony E-mount lenses, granting access to over 120 native lenses ranging from ultra-wide, prime, macro, professional telephoto, to specialized optics. This broad lens ecosystem means you can adapt your camera to landscapes, wildlife, portraits, sports, or macro work.

• The Sony W510 has a fixed zoom lens (26-104 mm equivalent, F2.8-5.9), covering general-purpose focal lengths, but no option to change lenses.

I tested the NEX-3N with several lenses, including fast primes and telephotos. The creative freedom when shooting portraits (with smooth bokeh and superior sharpness) or landscapes (at wide-angle with excellent distortion control) really shines. The W510’s lens, while convenient, felt limiting and optically less refined.

If you intend to grow your skills or specialize in any genre, the NEX-3N’s interchangeable lens system is a game-changer. The W510 suits casual users who prefer all-in-one simplicity.

Burst Rates and Video Features

Photography sometimes demands high frame rates or video capabilities - how do these two cameras deliver?

• The Sony NEX-3N offers a 4 fps burst shooting against the W510’s 1 fps. While not a speed demon, the NEX-3N can handle casual sports or wildlife sequences better.

For video:

• The NEX-3N records Full HD 1080p at 60i or 24p, in AVCHD or MPEG-4 formats - decent for entry-level video. However, there is no microphone input or headphone jack, limiting audio quality options.

• The W510 captures only VGA video (640x480) at 30fps in Motion JPEG, suitable just for casual clips.

Neither camera offers in-body stabilization (NEX-3N relies on lens stabilization if present; W510 has sensor-shift stabilization but in a fixed zoom). The lack of 4K or higher frame rates is expected given their release eras.

For serious video users, the NEX-3N provides a basic but credible platform. The W510 is strictly casual-video territory.

Battery Life and Storage

Shooting longevity is a practical concern. The NEX-3N uses a rechargeable NP-FW50 battery, rated for around 480 shots per charge - typical for entry-level mirrorless cameras. The W510’s NP-BN1 battery life isn’t officially stated, but generally smaller compacts can produce about 200-300 shots.

Both cameras accept SD cards, with the NEX-3N supporting SDHC and SDXC, and also Sony Memory Stick formats, giving some versatility. The W510 also supports these, but lacks faster UHS-I support.

For extended shooting sessions or travel, the NEX-3N’s better battery performance and card compatibility give it an edge.
