Olympus VR-320 vs Sony a5100: Picking the Right Camera for Your Photography Journey

Choosing your next camera is an exciting but challenging step, especially with so many options spanning compact superzooms to entry-level mirrorless models. Today, we put two distinct cameras head-to-head: the Olympus VR-320, a small sensor superzoom compact, and the Sony Alpha a5100, a lightweight APS-C mirrorless. Both cameras target enthusiasts but approach photography very differently – so understanding their strengths and limitations is key to finding the one that fits your needs.

We’ll dive deeply into their technology, real-world performance, and versatility across major photography types, along with detailed technical comparisons. Whether you’re just starting out or hunting a lightweight backup for pro work, this guide will demystify these cameras based on hands-on experience.

First Impressions: Size and Handling Matter

Before we explore specs, it’s important to consider ergonomics and physical design because if a camera doesn’t feel right in your hands, it won’t inspire confidence during shoots.

• Olympus VR-320 is ultra-compact (101 x 58 x 29mm) and lightweight at 158g. This compactness is great for casual travel and street photography where discretion and portability are priorities. It slips easily into a jacket pocket.

• Sony a5100 measures 110 x 63 x 36mm and weighs 283g – larger and heavier, but still small for an APS-C mirrorless. Its more substantial grip and control layout make it comfortable to hold for extended sessions and when paired with larger lenses.

In practice, the VR-320’s compactness favors travel and walk-around photography where sheer portability counts. The a5100, meanwhile, balances portability with a more traditional camera feel, appealing if you want a greater feature set without sacrificing much in terms of carrying convenience.

Top Controls and Interface: How You Work With Your Camera

Ease of use can define your shooting experience. Let’s look at how these cameras present controls and menus.

• Olympus VR-320: Focuses on simplicity - few external controls with no manual focus ring or dedicated dials. It’s optimized for automatic shooting, with a fixed lens and minimal-settings approach. The lack of manual exposure modes or shutter/aperture prioritization limits creative control but appeals to beginners or travelers who want point-and-shoot ease.

• Sony a5100: Offers traditional manual exposure modes (shutter priority, aperture priority, full manual) and a tilting touchscreen to access menus quickly. The inclusion of customizable buttons and a dedicated exposure compensation dial (via easy menus) lets you adapt settings fluidly. This model encourages growth into more advanced photography techniques.

If you highly value workflow speed and manual control, the a5100’s design offers a clear advantage. But for those who prefer simplicity and fast results without fiddling, the VR-320’s bare-bones control set is less intimidating.

Sensor Performance: The Heart of Your Images

Your camera’s sensor hugely impacts image quality - resolution, dynamic range, ISO performance, and depth of field capability, all trickle down from sensor size and technology.

Here’s a direct comparison:

What does this mean?

• The Sony a5100’s APS-C sensor is over 13 times larger in area than the VR-320’s 1/2.3” sensor. Larger sensors capture more light and detail, resulting in higher resolution images with finer tonal gradations and better high ISO noise control.

• The a5100 offers RAW file capture, giving you the flexibility to finely adjust exposure, white balance, and color profiles in post-production - a must-have for serious photographers.

• The VR-320’s small sensor means images will naturally have more noise at high ISOs and less dynamic range, limiting low-light performance and post-processing latitude.

If you value image quality and creative flexibility - especially for prints or detailed editing - the a5100 is the clear winner. The VR-320 is designed for easy sharing of casual photos, not professional-grade output.

Shooting Experience and Autofocus Performance

How the camera focuses and shoots in varied scenarios profoundly affects your ability to capture decisive moments.

• The Olympus VR-320 uses contrast-detection autofocus with face detection. It supports single AF and continuous AF tracking, which is decent given the simple fixed lens design, but it lacks manual focus and advanced tracking. Its shutter speed maxes out at 1/2000 sec, sufficient for general use but limiting in fast action.

• The Sony a5100 incorporates hybrid autofocus, combining contrast and phase detection with 179 focus points for exceptionally fast and accurate tracking, including face detection. It supports single, continuous, and selective AF modes, making it highly versatile for moving subjects.

Additionally, the a5100 can shoot at 6 frames per second continuous burst - useful for sports, wildlife, or dynamic street scenes - while the VR-320 lacks continuous shooting modes.

Again, who wins?

• For fast action and precise focusing, especially in challenging lighting or movement, the Sony a5100 excels.

• The VR-320 shines in leisurely family or travel shooting where speed and manual control are less critical.

Display and Viewfinder Options for Composition

While neither camera features a traditional viewfinder, their screen usability differs.

• The Olympus VR-320 has a fixed 3-inch TFT LCD with a 230k-dot resolution - a basic screen with limited brightness and angle flexibility.

• The Sony a5100 sports a 3-inch tilting LCD touchscreen at 922k-dot resolution, which is sharp and bright for composing in various lighting conditions. Touch focus and intuitive menu navigation enhance usability, especially when shooting video or selfies (though the a5100 is not marketed as selfie-oriented).

For composition flexibility and clear image review, the a5100’s advanced LCD is far superior.

Lens Ecosystem and Flexibility: Fixed vs Interchangeable

Naturally, lens choice defines your creative potential.

• The Olympus VR-320 has a fixed 24-300mm (12.5x zoom) lens with an aperture of f/3.0-5.9 - a versatile superzoom covering wide-to-telephoto ranges but limited in optical quality and low light due to the small sensor and narrow aperture.

• The Sony a5100 employs the Sony E-mount system with over 120 compatible lenses ranging from primes to zooms, macro lenses, and even adapted vintage glass. This system openness lets you shape your photographic style: from portraits with bright apertures to wildlife telephotos.

This difference is crucial: if you are starting out and want simplicity, the VR-320’s lens covers a lot of ground with no swaps needed. But if you desire growth and specialization, the a5100’s lens compatibility is a major advantage.

Battery Life and Storage: Staying Powered on Adventures

• The Olympus VR-320 uses a proprietary LI-42B battery, but official battery life ratings are not readily available. Given its small sensor and simple processor, battery consumption tends to be modest.

• The Sony a5100 includes an NP-FW50 battery rated for about 400 shots, considerably better suited for longer outings and more intensive usage - especially accounting for the bigger sensor and screen.

Both cameras support standard SD/SDHC cards; the a5100 also reads Memory Stick formats, adding options. Only one storage slot each is present, so carrying extra cards is advisable.

Video Capabilities: 720p vs Full HD

Video is significant for content creators, so understanding capabilities is key.

• The Olympus VR-320 records max 720p video at 30fps in Motion JPEG format. While acceptable for casual video, image quality and codec efficiency are limited, restricting editing flexibility.

• The Sony a5100 delivers Full HD 1080p at up to 60fps, supporting advanced video codecs like AVCHD and XAVC S, enabling smoother footage and higher-quality capture. The a5100 also offers slow-motion 720p at 120fps.

Neither camera offers 4K, external mic input, or image stabilization for video in-body (a5100 lacks stabilization entirely), but the a5100’s specs better suit vloggers and aspiring filmmakers who want more professional-looking results.

Build and Weather Resistance: Durability in Daily Use

Neither the Olympus VR-320 nor Sony a5100 are weather-sealed or shockproof cameras, so neither is ideal for extreme conditions or heavy outdoor abuse.

However:

• The VR-320’s pocket-friendly compactness offers natural protection from knocks.

• The a5100’s more substantial body has better materials and feels sturdy, more suitable for regular outdoor use with protective lens covers.

If you need rugged gear, consider this a must-move towards higher-tier models for serious weather sealing.
