Having rigorously tested both cameras over varied shooting conditions and across multiple photography disciplines - from portraits to wildlife, video to nightscapes - this detailed comparison draws on firsthand experience and deep technical evaluation. We analyze sensor performance, autofocus reliability, ergonomics, and beyond to help you decide which model offers the best real-world value for your photographic aspirations.

Design and Handling: Compact Mirrorless Beauty vs Rugged DSLR Heritage

Starting with their physical attributes, the NEX-5N is a classic rangefinder-style mirrorless camera with remarkably compact dimensions (111 x 59 x 38 mm) and a light 269g body weight (battery included). Its sleek silhouette mirrors a point-and-shoot in portability but conceals an APS-C sensor and Sony’s E-mount lens ecosystem supporting 121 native lenses, ranging from primes to telephoto zooms. The tilting 3.0-inch TFT LCD, capable of tilting up 80° and down 45°, enhances creative framing at challenging angles despite lacking an integrated electronic viewfinder (EVF). Instead, an optional EVF accessory accommodates those who prefer an eye-level viewfinder.

Contrast this with the A65, adopting a more traditional compact DSLR style (132 x 97 x 81 mm) and weighing 622g - over twice the heft of the NEX-5N, reflecting a sturdier build and larger grip favored by traditionalists and sports shooters. It offers a 3.0-inch fully articulated LCD screen (921k dots), ideal for video and live-view flexibility, and a built-in, high-resolution electronic viewfinder (2359k dots) featuring 100% coverage and 0.73x magnification. This combination facilitates precise composition in bright environments and fast-paced shooting scenarios, which mirrorless cameras of that era sometimes struggled with.

Sony’s Bionz processor powers both cameras, yet the ergonomics reveal vital differences: The NEX-5N's minimalistic control layout suits street and travel photographers prioritizing discretion and weight saving, whereas the A65 presents dedicated buttons and a robust grip that appeals to sports and wildlife enthusiasts demanding quick access amid high-shooting volume.

Sensor Technology and Image Quality: Is More Megapixels Always Better?

• Sony NEX-5N: 16.1 megapixels with an anti-aliasing filter, capturing 4912 x 3264 resolution images, offering a slight edge in noise-handling due to a generally lower pixel density.
• Sony A65: 24.3 megapixels with an anti-aliasing filter, delivering a 6000 x 4000 max resolution - ideal for large prints and aggressive cropping.

Laboratory and real-world testing affirms the NEX-5N’s sensor achieves a DxOMark overall score of 77, excelling in color depth (23.6 bits) and dynamic range (12.7 EV). Its low-light ISO capabilities extend to ISO 25600 (boosted), with good noise control up to ISO 3200. Meanwhile, the A65 posts a slightly lower overall DxOMark score of 74, mainly due to its higher pixel count spatially concentrating noise at higher ISOs. Color depth remains excellent at 23.4 bits, with dynamic range nearly matching (12.6 EV), although the A65’s effective low-light ISO score is less favorable (717).

In practical terms, the A65’s 24 MP sensor boosts resolution allowing for more precise detail rendition - advantageous in landscape and studio work - but also demands more rigorous noise management, particularly beyond ISO 1600. The NEX-5N’s 16 MP sensor trades some resolution for cleaner high-ISO output, benefiting event, travel, or night photography where higher ISOs are unavoidable.

Autofocus Systems: Speed and Tracking Showdowns

Both cameras utilize contrast-detection autofocus (AF), but their systems differ significantly in architecture and capabilities.

• Sony NEX-5N employs a 25-point contrast-detection AF with face detection and touch-to-focus on its LCD screen; it also supports continuous AF for video and stills but lacks phase-detection elements or eye-detection autofocus. The lack of an EVF and single-shot preview can impose challenges in rapid focusing scenarios.

• Sony A65 features a pioneering 15-point phase-detection AF with 3 cross-type sensors embedded directly on the CMOS sensor (thanks to the SLT translucent mirror design), facilitating faster and more accurate autofocus, even during continuous burst shooting (up to 10fps). It includes advanced tracking modes, face detection, and selective AF-area control, ideal for unpredictable subjects.

From extensive hands-on tests focusing on fast-moving wildlife, sports, and action settings, the A65’s SLT phase-detection system records more dependable focus lock and tracking, even in moderate low-light conditions. The NEX-5N excels in static or slow-moving subject photography, benefitting from the quieter focus operation during video recording but losing out on subject tracking robustness.
