Olympus E-P5 vs. Sony W810: A Crossroads of Mirrorless Ambition and Ultracompact Simplicity

When faced with two vastly different cameras - an Olympus PEN E-P5 mirrorless contender from 2013 and the humble Sony Cyber-shot DSC-W810 ultracompact from 2014 - what’s a photography enthusiast to do? How to compare a serious Micro Four Thirds system camera against a budget-friendly, pocketable point-and-shoot? That’s exactly the kind of challenge I relish, and after pushing both through their paces over many weeks, I’m ready to break down their real-world performance, technical muscle, and value. Whether you’re chasing pixel-perfect portraits or just want a grab-and-go snapshotter, this deep dive will clarify which camera suits your style - and why.

Let’s start this photographic tête-à-tête with a friendly face-off of their physical presence.

Size Matters: Handling and Ergonomics in the Real World

At first glance - and in first touch - the Olympus E-P5 feels like a tool designed with passion. It carries the classic rangefinder-style mirrorless DNA: compact for a serious interchangeable lens camera yet substantial enough to inspire confidence. Weighing in at 420 grams and measuring 122×69×37 mm, the E-P5 is nowhere near bulky but has a tactile heft that beckons the enthusiast.

The Sony W810, on the other hand, is the study in ultracompact convenience. At a mere 111 grams and 97×56×21 mm, it vanishes into a jacket pocket or purse with ease. Its thin slab body screams simplicity and portability. Perfect for those days when a DSLR or even a mirrorless feels like overkill.

The Olympus’s grip design and button placement cater to sustained shooting sessions, comfortable even for folks with medium to large hands. The Sony’s minimalist button layout - and I use that term generously - reflects its casual snapshot target audience. You won’t find direct access to aperture or shutter priority modes here, just straightforward point and shoot.

Still, small can be mighty if portability is your priority.

Glancing down from above confirms the different philosophical approaches. The E-P5 sports a traditional mode dial, a prominent shutter button, and customizable physical controls that reward quick access - critical for action or street shooters who need fast reflexes. Meanwhile, the W810’s top is pared down to the essentials: shutter release, zoom toggle, flash control, and power switch. No surprises, but also little room for creative spontaneity.

The Heart of the Matter: Sensors and Image Quality

Comparing sensors here is like pitting a thoroughbred racehorse (E-P5) against a sprightly pony (W810). The Olympus boasts a 16MP Four Thirds CMOS sensor measuring 17.3x13mm (~225mm²), while the Sony relies on a tiny 1/2.3" CCD with 20MP resolution squished into 6.17x4.55mm (~28mm²).

Sensor size is crucial because it directly impacts image quality - dynamic range, color depth, low noise, and sharpness. In my extensive shooting tests, the E-P5’s larger sensor manifests in richer color gradations, better shadow recovery, and superior overall image fidelity, particularly in challenging lighting.

Sony’s W810 can produce decent daylight snaps but struggles with noise and limited dynamic range as you ramp up ISO beyond its modest ceiling of 3200. The CCD sensor technology is older and less sensitive to light compared to modern CMOS designs.

In fact, the E-P5 shines in producing skin tones for portrait work that appear natural and nuanced - a rare feat for cameras in this class. The Sony’s smaller sensor and lack of RAW output (no raw support here) tightly limits post-processing latitude.

Bottom line: If image quality and creative control are priorities, Olympus’s sensor is in a different league.

Viewing Your Shots: LCD and Interface Usability

You might not believe a screen can influence your experience so dramatically, but trust me - it's essential. The E-P5 sports a 3-inch tilting LCD touchscreen with 1037k-dot resolution - sharp, bright, and versatile for shooting at odd angles.

The Sony W810’s 2.7-inch fixed LCD with only 230k-dot resolution is serviceable - but noticeably less crisp - and non-touch, which feels archaic by today’s standards.

The touchscreen on the E-P5 adds convenience for quick focus adjustments and menu navigation - especially welcome in street or landscape scenarios where nimbly changing settings can inspire better shots.

Conversely, the W810’s interface is straightforward but slow. No touchscreen means hunting through menus. Autofocus points are limited and mostly center-weighted; exposure compensation and manual modes are non-existent.

These differences support the Olympus’s more professional ambitions while Sony clearly skews towards casual users.

Autofocus and Burst Performance: Catch the Moment or Simply Snap

When shooting wildlife or sports, autofocus speed and accuracy aren’t just bells and whistles - they’re mission critical. Having tested both cameras in action, here’s how they stack up.

The Olympus E-P5 employs a contrast-detection AF system with 35 focus points and face detection, plus 9fps continuous shooting - impressive for a 2013 mirrorless camera. While it lacks phase-detection AF (now a standard in newer mirrorless), its quick autofocus tracking keeps decent pace chasing moderately fast subjects, especially under good light.

The Sony W810 is limited to single AF mode with relatively sluggish focusing and a paltry 1fps continuous rate - practically an invitation to miss the decisive moment. Its fixed lens and lower processing power further constrain its burst options.

Autofocus coverage is also telling: the E-P5’s wider points and face detection provide better framing freedom; W810’s AF is fixed-center and fiddly.

So if you want to freeze action or wildlife behavior, Olympus is significantly better equipped.

Weather Sealing and Build Quality: Ready for Journey or Stay Home?

Neither camera sports weather sealing or rugged body components - a bit of a letdown for Olympus, given its semi-pro ambitions - especially compared to peers like the Panasonic GH series. The E-P5’s metal alloy body, however, feels robust and well put-together: it’s designed to endure enthusiastic use.

Sony’s W810, built from plastic and supplied with a basic fixed zoom, targets casual shooters, thus justifies its lighter-duty construction. For travel, it’s easy to stash, but you’ll want a rain cover for damp environments.

If you prioritize durability and weather protection for landscape or travel photography, you’ll want to budget more or supplement with accessories.

Lenses and System Expansion: From Versatile to Fixed

Here’s where Olympus’s Micro Four Thirds system shines. With a staggering 107 lenses available - ranging from ultra-wide primes to super-telephoto zooms, macros, and specialty optics - the E-P5 is your gateway to photographic creativity across genres: portraits, wildlife, macro, and more.

The Sony W810’s fixed lens zoom covers 27–162 mm (in 35mm equivalence), a reasonable all-purpose range, but you’re stuck with it. Aperture ranges from F3.5 at wide end to F6.5 at telephoto, which translates into limited low light and shallow depth-of-field control.

For anyone serious about refining their craft through changing lenses, Olympus’s open ecosystem is invaluable.

Battery Life and Storage: Powering Your Passion

In real-world terms, the Olympus E-P5’s battery life rates around 330 shots per charge, which isn't record-breaking but quite typical for mirrorless systems of its era. The Sony W810 lags with about 200 shots per battery, partly due to its small battery being designed for sporadic use.

Storage-wise, the Olympus supports standard SD/SDHC/SDXC cards, compatible with large capacity UHS-I cards - vital for handling its RAW files and burst sequences. The Sony accepts Memory Stick Duo and microSD cards, limiting flexibility if you use these cards elsewhere.

Professional use demands longer sessions, so Olympus’s battery management combined with an external charger and spare batteries is highly advisable.

Connectivity and Sharing: Wired for the Modern Age

Olympus packed the E-P5 with built-in wireless connectivity (Wi-Fi), allowing seamless image transfer and remote camera control via smartphone apps. USB 2.0 and HDMI ports provide further data and video connectivity options.

The Sony W810 offers no wireless whatsoever. USB 2.0 is present, but there’s no HDMI output or smartphone app support. That’s acceptable given the price and category but disappointing to anyone envisioning instant sharing or remote capture.

If you prize wireless flexibility and integration into a digital workflow, Olympus is the clear winner.

Video Capabilities: HD, but Not for Cinematic Aspirations

The Olympus E-P5 offers full HD 1080p video at 30fps using H.264 compression with options for external microphones lacking (no mic input) but includes built-in stabilization for smoother clips. Its tilting touchscreen aids framing.

Sony’s W810 records only 720p HD video at 30fps, again limited by fixed lens and lack of stabilization efficacy. The lack of manual exposure controls and audio ports again defines it as casual.

Neither is a filmmaker’s dream. But for casual video diaries, Olympus provides better quality and flexibility.

Genre-Focused Performance: What Do Photographers Think?

Let’s glance at genre-specific scores derived from hands-on testing and professional evaluations of each camera’s performance.

The Verdict From a Seasoned Tester

After thousands of hours testing cameras from all categories, the Olympus E-P5 remains a compelling choice for those stepping into advanced mirrorless photography today - especially if you can find it in deals or used markets around $400. It holds its 2013-era crown well, providing a solid balance of image quality, handling, and expandable system benefits.

The Sony W810 is exactly what marketing promised: a simple compact camera for spontaneous, casual use. It isn’t a serious creative tool, and its older sensor tech shows. But if your test is “point, shoot, and share via card reader,” it’s a no-fuss option.

For photographers who seek durability, flexibility, and high image quality in a small footprint, Olympus E-P5 is the clear winner. For casual, budget-minded snapshotters, the Sony W810’s size and simplicity are appealing.

Photography is personal, and that’s why I always suggest hands-on trials or rentals before commitment. But I hope this detailed comparison helps you see beyond specs sheets into what truly matters - the joy and quality of your images.

Happy shooting!
