From Superzoom Simplicity to Mirrorless Mastery: Comparing Olympus VR-320 vs Sony A6400

Choosing your next camera can feel like gazing across a sprawling landscape of models and specs, with each brand claiming unique advantages. Today, we’ll dive deep into a head-to-head comparison between two rather different beasts: the Olympus VR-320, a compact superzoom from 2011, and the Sony Alpha A6400, a more recent advanced mirrorless camera from 2019. At first glance, this might seem like comparing apples and oranges, but that’s exactly why it’s fascinating.

Having tested thousands of cameras over 15 years, I’ll walk you through their real-world capabilities across major photography disciplines, technical performance, and ultimately who they’re best suited for. Expect detailed insights, practical takeaways, and a few surprises along the way.

Let’s start by sizing them up, quite literally.

Size and Handling: Pocketable Simplicity vs Ergonomic Flexibility

Right out of the gate, the physical difference is striking. The Olympus VR-320 is a compact, lightweight point-and-shoot designed for casual carry, while the Sony A6400 embraces a larger, more solid rangefinder-style mirrorless body for enthusiast use.

Measuring roughly 101 x 58 x 29 mm and weighing just 158 grams (with battery), the Olympus slips effortlessly into a pocket or small bag. It’s the kind of grab-and-go camera you’ll have ready for spontaneous shoots, especially travel or street snaps. The ergonomics are minimal - no grip to speak of, and a straightforward control layout - perfect if you prefer simplicity without fussing over settings.

On the other hand, the Sony A6400’s dimensions (120 x 67 x 50 mm) and heftier weight of 403 grams reflect its advanced build and manual controls. The grip feels natural for extended handheld shooting and the button layout supports quick access to essential functions. This is a camera built for deliberate photography sessions rather than casual snapshots.

If you prize ultra-portability and ease of use above all else, the Olympus wins points here. But if you want a more substantial, tactile experience where controls are at your fingertips, the Sony sets a higher bar.

Sensor and Image Quality: Small CCD vs Large APS-C CMOS

Of course, the heart of any camera is the sensor, and here the gap between these two widens significantly.

The Olympus VR-320 features a 1/2.3-inch CCD sensor (6.17 x 4.55 mm), delivering 14 megapixels at a maximum native ISO of 1600. Given its tiny sensor area of just under 28 mm², noise performance and dynamic range are inherently limited. CCD sensors of this era tend to favor less video-friendly readout but offered respectable image quality for casual snapshots.

By contrast, Sony’s A6400 boasts a much larger APS-C sensor (23.5 x 15.6 mm) with 24 megapixels, nearly 13 times the sensor area of the Olympus - a major factor in superior image quality. This CMOS sensor pairs with Sony’s Bionz X processor to provide excellent dynamic range, color depth, and low-light capability (native ISO up to 32000, expandable to 102400).

What does this mean practically? Images from the A6400 have richer tonal gradation, greater detail, and superior performance in shadows and highlights. ISO noise remains controlled well beyond ISO 1600, something the Olympus struggles with due to sensor and processing limits.

For landscape and professional portrait shooters wanting top image quality and RAW flexibility (Sony supports RAW, Olympus does not), the A6400 is the unmistakable winner here. The Olympus may suffice for casual shooters or snapshots to share on social media, but it falls short if precise image quality is your goal.

Ergonomics and User Interface: Fixed LCD vs Tilt Touchscreen

Controls and user interface matter just as much as sensor specs, especially when you’re on the move or switching shooting modes frequently.

The Olympus has a fixed 3-inch TFT color LCD with 230k-dot resolution. It’s simple and functional but lacks touch or tilt mechanisms. Composing can sometimes be tricky in bright sunlight, given no electronic viewfinder (EVF) to turn to.

Sony’s A6400, meanwhile, offers a 3-inch tilting screen with a 921k-dot resolution and full touchscreen responsiveness. This versatile monitor makes composing at high or low angles effortless, and the touchscreen speeds up menu navigation and focus point placement.

The A6400’s inclusion of a high-resolution electronic viewfinder (2359k dots, 100% coverage) is a huge plus for precise framing in bright outdoor conditions, where LCD screens might struggle.

If you shoot a lot outdoors or like composing in varied positions, Sony's versatile interface will feel like a breath of fresh air. The Olympus keeps things simple but misses the ergonomic refinements many photographers now expect.

Autofocus and Speed: Basic Contrast Detection vs Cutting-Edge Hybrid System

Focusing speed and accuracy often decide how many great photos you capture, especially in fast-paced situations.

The Olympus VR-320 uses a basic contrast-detection autofocus system, limited to single AF mode with no manual focus option. It offers multi-area AF and face detection but nothing comparable to modern AF tech. Tracking moving subjects is moderately supported, but you’ll notice hunting and slow lock-on, especially in low light.

Conversely, the Sony A6400 features an advanced hybrid autofocus system with 425 phase-detection points and contrast detection, covering a wide focal area. This system excels in speed, precision, and tracking, including eye and animal eye AF modes - a game changer for portrait, wildlife, and sports photography.

Sony’s burst shooting at 11 fps with continuous autofocus outperforms the Olympus by miles, letting you capture decisive moments in action settings.

If you often shoot fast-moving subjects or want reliable focus in tricky environments, the Sony’s autofocus technology delivers professional-grade performance. For stationary subjects or casual use, the Olympus may suffice, but don’t expect high-speed responsiveness.

Lens System: Fixed Superzoom vs Interchangeable E-mount Ecosystem

One major difference is lens flexibility. Olympus bundles the VR-320 with a fixed 24-300 mm equivalent zoom (12.5x), aperture F3.0-5.9, giving impressive reach in a pocketable package. It also supports macro shooting as close as 1 cm. While versatile for general use, the fixed lens means you can’t swap optics for specialized needs.

Sony’s A6400 uses the Sony E-mount, a rich and mature ecosystem with over 120 lenses ranging from ultra-wide primes and telephoto zooms to macro and cine lenses.

This opens doors for every photography discipline:

• Portraits with fast, bright primes for creamy bokeh
• Landscapes with sharp wide-angle lenses
• Wildlife with super-telephoto zooms
• Macro with dedicated close-focus optics
• Video by adding stabilized cinema lenses

Personally, I always gravitate towards cameras with interchangeable lenses if I want to pursue multiple genres seriously. Olympus’s fixed zoom is convenient, but it’s a one-trick pony compared to Sony’s flexibility.

Build and Weather Resistance: Lightweight Simplicity vs Durable Construction

For photographers who brave outdoors or variable weather, build quality and weather sealing matter.

The Olympus VR-320’s plastic compact body lacks any weather or dust sealing. Its light weight makes it easy to carry but more vulnerable to knocks or moisture.

Sony’s A6400 features a robust, partially weather-sealed magnesium alloy body, offering resilience against dust and light rain. While not fully waterproof or shockproof, the ruggedness inspires confidence in professional scenarios or outdoor adventures.

If you shoot landscapes in remote areas or wildlife in unpredictable weather, the Sony’s build quality better supports your work. Casual photographers less concerned with ruggedness might find Olympus’s design acceptable for everyday use.

Video Capabilities: Modest HD vs 4K and Professional Audio

Video recording has become essential for many photographers, and here the two cameras diverge sharply.

The Olympus VR-320 records modest HD video at 1280x720 pixels up to 30 fps using Motion JPEG - a format that results in large files and modest quality. It lacks microphone or headphone jacks, and no 4K option is available.

Sony’s A6400 supports full Ultra HD 4K at 30p with high bitrates (XAVC S codec), delivering cinematic-quality footage. It has a microphone input (though no headphone out) for better audio capture. Plus, features like focus peaking and zebra exposure assist in manual video control.

If you prioritize video quality alongside stills, the A6400 offers a clear advantage. Olympus’s video is functional for simple clips but won’t satisfy serious videographers.

Battery Life and Connectivity

The Olympus uses a small LI-42B battery with limited life, designed for casual use - typical for compacts. It offers USB 2.0 but lacks wireless features.

Sony’s A6400 utilizes the NP-FW50 battery providing approximately 410 shots per charge - respectable for a mirrorless. It includes built-in Wi-Fi, Bluetooth, NFC, and HDMI output for connectivity and remote control.

If staying connected and shooting longer sessions is important, Sony’s system is more future-proof.
