Sony NEX-5 vs Sony A65: A Deep Dive into Two Entry-Level Sony Cameras

When selecting an entry-level camera, especially within the Sony ecosystem, photographers must carefully weigh sensor capabilities, autofocus performance, handling, and feature sets relative to their personal application. The Sony NEX-5 and the Sony A65 represent strategic though contrasting offerings from Sony’s 2010-2011 lineups: the NEX-5 as an early mirrorless model targeting portability and innovation, and the A65 as a compact DSLR (technically an SLT) emphasizing traditional ergonomics and speed. This comparison elucidates the key technical and practical differences between these two cameras across all major photographic disciplines, ending with well-grounded purchase recommendations.

Understanding the Core Platform Differences: Mirrorless vs SLT Design

At the architectural level, these cameras are designed for divergent user experiences.

• Sony NEX-5:
  Styled as a rangefinder mirrorless, the NEX-5 omits a viewfinder, relying solely on its tilting 3.0-inch LCD (920k dots) for composing. Its compact dimensions (111×59×38 mm) and weight of 287g strongly emphasize portability. The lack of in-body stabilization, simplified control layout, and a 14MP APS-C CMOS sensor with Sony’s early Bionz processor underline its position as a bridge camera for enthusiasts moving from compacts or DSLRs, willing to trade advanced features for size and ease.

• Sony A65:
  The A65 adopts Sony’s translucent mirror technology (Single-Lens Translucent or SLT) enabling phase-detection autofocus on the main sensor and an electronic viewfinder (EVF) with very high resolution (2359k dots), 100% coverage, and 0.73x magnification. Its rugged DSLR-style body (132×97×81 mm) weighing 622g, fully articulated 3.0-inch screen (921k dots) and a more powerful 24MP APS-C sensor distinguish it as a more advanced, speed-optimized tool. It includes sensor-based image stabilization and built-in flash, enhancing flexibility.

Size and ergonomics show the tradeoff: portability of NEX-5 vs the bulk and substantial grip and control surface of the A65.
