Olympus E-P5 vs Sony W320: A Comprehensive Real-World Camera Showdown

When faced with two cameras as distinct as the Olympus PEN E-P5 and the Sony Cyber-shot DSC-W320, it’s tempting to wonder if they even belong in the same conversation. One is a stylish Micro Four Thirds mirrorless camera aimed at enthusiasts who cherish control and image quality, while the other is a compact point-and-shoot designed primarily for casual shooters seeking simplicity and portability. But as a photographer who has tested thousands of cameras over the last 15 years, I can assure you - there’s more to compare beneath the surface than you might expect.

Let’s dive into a thorough comparison of these two, unpacking their technical specs, usability, and performance in a variety of photographic disciplines - from landscape to wildlife, portraiture to video, and everything in between. We’ll also explore their ergonomics and value propositions so you can make an informed decision that best fits your photographic style and budget.

The Tale of Two Bodies: Size, Handling, and Build Quality

Before you even press the shutter, the physical presence of a camera massively influences the shooting experience. Here, the Olympus E-P5 and Sony W320 couldn't be more different.

The Olympus E-P5, announced back in late 2013, embraces a classic rangefinder-style mirrorless form with a solid metal chassis, measuring 122x69x37mm and weighing approximately 420 grams - notably chunky for a Micro Four Thirds camera, but pleasantly reassuring in hand. Its robust build, while not fully weather-sealed, has a confident mid-range DSLR heft, positioning itself for serious photographers who crave manual controls and durability without lugging around a beast of a DSLR.

In contrast, the Sony W320 (released in early 2010) is the definition of ultracompact - just 93x52x17mm and tipping the scales at 117 grams. That’s pocketable in the truest sense. If you’re the type who captures fleeting moments on the go without wanting to carry additional gear or mess with settings, this camera’s diminutive stature is tempting.

However, this size difference comes with compromises. The Olympus sports a tilting 3-inch touchscreen LCD, enhancing compositional flexibility and intuitive operation, whereas the Sony has a fixed 2.7-inch LCD that doesn’t support touch input. Ergonomically, the E-P5 features a well-laid-out control scheme with dedicated dials for shutter speed, aperture, and exposure compensation, a welcome change for those fluid manual operations. The Sony, meanwhile, keeps things minimal with a few buttons primarily geared towards ease rather than precise control.

Durability-wise, neither camera is sealed against weather, dust, or shocks - so pack accordingly if you head outdoors in harsher conditions. Yet the Olympus’s metal body lends it a more premium feel and higher perceived resilience.

Peeking Under the Hood: Sensor & Image Quality Comparison

In the realm of image fundamentals, sensor technology sets the stage for everything else - from dynamic range to noise performance to resolution.

The Olympus E-P5 is outfitted with a 16MP Four Thirds CMOS sensor sized 17.3x13mm, covering an area of roughly 225 mm². This sensor benefits from Olympus’s long-standing Micro Four Thirds lens ecosystem - currently boasting over 100 native lenses - which means excellent versatility in focal length and aperture selections.

Meanwhile, the Sony W320 relies on a much smaller 1/2.3" CCD sensor (6.17x4.55mm, about 28 mm²), with a resolution of 14 megapixels. Compared to the Olympus, it’s barely more than an afterthought in terms of size, which inevitably restricts its ability to capture fine detail and handle noise gracefully at higher ISOs.

In practical testing across various lighting conditions, the Olympus sensor flexes its muscles better. The E-P5 delivers crisp files with excellent fine details at base ISO 100, maintaining image integrity up to ISO 1600, and even usable results up to ISO 3200 - a boon for low light shooting. Its DxO Mark scores reflect this with an overall of 72, 22.8 bits color depth, and a dynamic range of 12.4 EV - impressive for an older Four Thirds sensor.

Conversely, the Sony W320’s smaller CCD struggles beyond ISO 400, producing significantly more noise and muddier color transitions. The dynamic range and color depth are notably lacking (and untested by DxO), making it better suited for daylight, well-lit shots where its sensor limitations don’t show.

Seeing the World: Viewscreens and Viewing Experience

Modern shooting demands a reliable and flexible viewfinder setup, and here again the Olympus asserts its higher-end credentials.

The E-P5 offers a 3-inch 1037k-dot tilting capacitive touchscreen - responsive and bright, tactilely superior, allowing easier framing from tricky angles. While it doesn’t have a built-in electronic viewfinder (EVF), Olympus offers an optional accessory EVF that plugs neatly into the hot shoe for eye-level composing.

Sony’s W320, in classic compact style, lacks any sort of electronic or optical viewfinder, relying solely on its fixed LCD screen with a marginal 230k-dot resolution - which can feel cramped and less readable under bright sunlight.

In my experience shooting on sunny days, the W320’s screen was frustratingly reflective, forcing me to constantly shade it for proper framing. The E-P5’s screen, by contrast, remains visibly crisp and responsive with touch-based focus point selection, a feature sorely missed on the Sony.

The Control Room: Top Layout and Handling Dynamics

A camera’s top plate can tell you a lot about its intended user group. Does it favor simplicity or granular control?

The Olympus E-P5 sports a cleanly designed top with dedicated shutter speed and exposure compensation dials, a mode dial, and customizable function buttons. This layout encourages fast adjustments without diving deep into menus - a blissful experience for users who appreciate tactile feedback and control finesse.

In contrast, the Sony W320 adopts a minimalistic top design, centered around the power button, shutter release, and zoom rocker. There are no dedicated dials for exposure control or modes, and all settings are navigated through menus.

For photographers who revel in tweaking settings on the fly - say portrait or landscape photographers seeking precise exposure or depth-of-field control - the Olympus readily caters to that mindset. The Sony tends to suit casual point-and-shooters happy letting the camera handle the technical details.

Portrait Photography: Rendering Skin and Nailing Focus

Portrait work demands flattering skin tone reproduction, creamy bokeh, and reliable eye detection autofocus to keep expressions sharp.

Thanks to the Olympus’s larger sensor, higher-quality glass, and mature autofocus system (35 points with face-detection and continuous AF), it generally produces portraits with more natural, detailed skin tones and softer, more beautiful background blur - essential for subject separation.

Sony’s W320 fixed 26-105mm equivalent zoom can deliver decent snapshots in good light. However, its maximum aperture range of f/2.7-5.7 and small sensor limit shallow depth-of-field effects and low-light focusing. Face detection is absent, and autofocus is contrast-based and slow, often hunting in dimmer situations.

In real portraits, the Olympus’s eye-detect AF proved to be a game-changer, locking precisely onto eyes even with slight movement - a feature missing on the Sony, which often missed critical focus points or lagged behind.

Landscape and Nature: Going Wide and Managing Dynamic Range

If you’re chasing sunrises, dramatic skies, or sweeping vistas, dynamic range, resolution, and weather resilience matter.

The Olympus E-P5, with its 16MP sensor and native four-thirds lenses covering wide-angle primes and zooms, easily produces high-resolution landscape images with excellent tonal gradations - highlighting shadows and retaining highlight details without crush.

While the Sony W320's lens offers a 26mm wide equivalent, its modest sensor and 14MP resolution can struggle in tricky lighting. The JPEG output often shows early clipping of highlights or blocked shadows.

Neither camera is weather-sealed; however, the E-P5’s sturdier build better withstands outdoor use. If you want durability and versatility for serious landscape capture, Olympus offers a clear edge here.

Wildlife and Action: AF Speed, Burst Rates, and Reach

When the moment is fleeting - a bird mid-flight or a racecar zooming past - autofocus speed, continuous shooting, and telephoto reach are paramount.

Olympus punching in with 9 frames per second continuous burst and 35 AF points (contrast detection) offers respectable tracking in good light. With access to native telephoto lens options on Micro Four Thirds, the E-P5 can achieve effective focal lengths beyond 400mm - crucial for distant wildlife.

Sony W320 hobbles along with just a single frame per second burst and a fixed lens maxing at 105mm equivalent, limiting its utility for distant subjects or sports.

In hands-on trials, the Olympus gave much better chances to nail sharp frames of moving subjects, whereas the Sony’s focus lag and limited zoom made wildlife or sports photography an exercise in patience.

Street and Travel Photography: Discretion Meets Versatility

Street shooters value compactness, quiet operation, and fast startup - but also appreciate manual control and decent image quality.

While the Sony W320 excels in pocketability and silence due to its fixed lens and quiet mechanics, its image quality and focus speed in variable lighting can be frustrating.

The Olympus E-P5, though larger and noisier (its shutter is audible), offers silent electronic shutter mode at up to 1/8000 sec, aiding street shooting discretion. Plus, its tilting screen lets you shoot from waist-level, blending into crowds better.

For travel, the Olympus’s battery life of approximately 330 shots per charge and versatility with dozens of lenses make it a more flexible companion. The Sony’s lack of wireless connectivity and shorter battery life (unpublished, but generally less than Olympus) might limit longer shooting adventures.

Macro and Close-Up: Focusing Precision and Magnification

None of these cameras are dedicated macro specialists, but with the right glass, they both can entertain close-up work.

Olympus’s native Micro Four Thirds mount grants access to specialized macro prime lenses with impressive magnification ratios and close focusing distances.

Sony’s W320 offers a macro mode down to around 4cm but lacks fine focusing control or image stabilization.

Here, Olympus again takes the lead due to its superior focusing accuracy, sensor-shift image stabilization (5-axis), and the ability to manually focus with high precision.

Night and Astro Photography: High ISO and Exposure Versatility

Astro enthusiasts and night photographers judge cameras by ISO performance and exposure control.

Olympus E-P5 performs admirably up to ISO 1600-3200, with acceptable noise and considerable dynamic range preserved. Its shutter speed range (60 seconds to 1/8000 sec) supports long exposures needed for star trails or nightscapes.

The Sony’s max native ISO is 3200, but noise builds up rapidly past ISO 400. Its max shutter speed of 1/1600 sec and minimum 1-second exposure restrict versatility in prolonged low-light exposures.

Olympus further benefits from flexibility with manual exposure modes and bracketing to tackle tricky lighting - luxury not available on the Sony.

Movie-Making: Video Capture Capabilities and Features

Video is no longer an afterthought for many photographers, and the Olympus E-P5 supports Full HD 1080p video at 30fps (H.264 codec) with sensor-based 5-axis image stabilization - a boon for smoother handheld footage.

The Sony W320 is more modest with VGA resolution at 640x480, limiting it to basic home movies and snapshot video.

Neither camera offers external microphone ports or 4K recording, but the Olympus’s video quality and IS framework place it head and shoulders above the Sony.

Workflow, Storage, and Connectivity

The Olympus accepts standard SD/SDHC/SDXC cards, a single slot, and uses USB 2.0 along with built-in Wi-Fi (but no Bluetooth or NFC). Images can be captured in RAW and JPEG, critical for workflow flexibility.

Sony W320 supports SD cards and Memory Stick Duo types, but no RAW support - meaning limited editing latitude later.

Olympus’s touch interface and post-processing options also smooth the editing pipeline, while Sony’s simplicity may hamper advanced photographers.

Price-to-Performance: Who Gets the Best Bang for Their Buck?

At launch, the Olympus E-P5 priced around $389 - quite aggressive given its feature set, sensor size, and lens compatibility.

The Sony W320 was introduced near $269, appealing to budget buyers needing simple snapshots.

Fair assessment? The Olympus is better suited for enthusiasts and professionals seeking compact versatility with quality and manual control. The Sony is a basic ultracompact for casual, snapshot photography.

Ultimately, if image quality, creative control, and longevity matter, the Olympus wins hands down, despite higher cost and bulk.

Summing Up Performance Scores

Reflecting on my tests and scores, the Olympus E-P5 leads clearly with better scoring in image quality, autofocus, speed, and video. The Sony W320 is a lightweight contender for basic everyday shooting with its own place.
