Ricoh GXR A16 24-85mm vs Sony A6400: Which Mirrorless Camera Is Right for You?

Choosing the right camera involves balancing sensor technology, autofocus prowess, handling, image quality, and your unique shooting preferences. In this in-depth comparison, I put two advanced mirrorless cameras head-to-head: the Ricoh GXR A16 24-85mm F3.5-5.5 from 2012, and Sony’s 2019 Alpha A6400. Both rangefinder-style mirrorless models target enthusiasts wanting compact designs, but they come from different eras with distinct approaches. Drawing from my extensive experience testing thousands of cameras across genres, I’ll dissect their technical features, real-world performance, and usability - helping you decide which fits your photography needs best.

A Tale of Two Generations: Design and Ergonomics

Despite both sporting a compact, rangefinder-style body, the Ricoh GXR and Sony A6400 feel quite different in hand due to their design priorities and build attributes.

Ricoh GXR A16 24-85mm

The GXR’s core distinction is its fixed lens module - the sensor and lens are inseparable, forming a single unit. It’s a concept that offers excellent integration between lens and sensor but sacrifices the flexibility of swapping optics. The GXR’s dimensions (114x75x93mm) and weight (550g) reflect a balanced but somewhat chunky body due to this integration.

This model has a straightforward control layout, minimalist in design, without a dedicated electronic viewfinder (EVF) built-in - there’s an optional EVF you can add. The 3-inch fixed TFT LCD screen (resolution 920k dots) doesn’t articulate or touch-enable, which can limit usability in some shooting scenarios.

Sony A6400

By contrast, Sony’s A6400 embraces modularity with a classic interchangeable lens mount (Sony E-mount). The body is more compact and lighter (120x67x50mm at 403g), making it easier to carry for extended sessions or street photography.

Sony includes a high-resolution (2359k dots) 0.7x magnification EVF and a tilting 3-inch touchscreen LCD (922k dots). The touchscreen greatly enhances usability with features like touch-to-focus and intuitive menu navigation.

In my hands-on tests, I found the A6400’s ergonomics more refined and adaptable - the smaller, lighter body combined with a robust grip and responsive controls encourages prolonged use without fatigue.
