Olympus OM-D E-M1X vs Sony Cyber-shot DSC-W310: An Expert Comparison for Every Photographer

When it comes to cameras, the options out there are a wild spectrum - from tiny point-and-shoots stuffed in your pocket to pro-level mirrorless beasts designed for serious work. Today, I’m diving deep into two wildly different cameras: Olympus’ powerhouse E-M1X and the humble Sony W310 compact. The difference is almost comical on paper, but as someone who’s spent years testing both ends of this spectrum, I want to walk you through their practical strengths, real-world performance, and lifestyle fit. Ultimately, I’m here to help you answer a critical question: which camera fits your shooting style, budget, and ambitions?

Let’s get into it.

Size, Handling & Ergonomics: Clubs for Thumbs vs Pocket-Sized Convenience

At first glance, you couldn’t find two bodies more different. The Olympus E-M1X is a full pro-level mirrorless camera - large, hefty, and built like a tank - while the Sony W310 is a tiny ultracompact designed for casual shooters.

Olympus E-M1X weighs in close to 1kg and is basically a camera that dares you to hold it with one hand comfortably. It follows a DSLR-style mirrorless design with a deep grip and lots of physical controls packed in. This is a camera built for marathon shoots with clubs for thumbs - lots of customizable buttons, dual card slots, and two shutter buttons for shooting vertically or horizontally.

Meanwhile, the Sony W310 is a featherweight at 137 grams and roughly the size of a small candy bar. It slips effortlessly in your pocket, rocking a fixed lens and a stripped-down interface optimized for straightforward point-and-shoot use.

If you prize ultimate control and don’t mind carrying extra weight, Olympus’ ergonomics are a joy to experts. For everyday grab-and-go snapshots or budget-minded casual use, the W310 wins hands-down on portability and no-fuss simplicity.

Interface & Control Layout: Pro Precision vs Beginner Ease

Looks matter at the control level too. The Olympus boasts an articulated 3-inch touchscreen with over 1 million dots resolution, complemented by a bright 2.36M-dot electronic viewfinder (EVF). It’s responsive, offers touch focus, eye-detection AF control, and effectively lets you tailor your shooting experience.

The Sony’s fixed 2.7-inch screen has just 230K dots - well below today’s crisp display norms - and no EVF to speak of. No touchscreen means you’re clicking buttons instead of tapping controls, which is fine for beginners but feels archaic after trying pro gear.

From my hands-on time, the Olympus interface - with physical dials, dual command wheels, and an intelligently laid out menu system - is a dream for advanced users. You get quick access to aperture, shutter priority, exposure compensation, and more, even with gloves on.

In contrast, the Sony’s minimal buttons and no touchscreen keep things simple, but often feel clunky if you want any manual control or fast setting changes.

Sensor Tech & Image Quality: Micro Four Thirds Powerhouse vs Tiny CCD Snapper

This is where the gulf truly opens up - and sensor specs tell the story.

The Olympus flaunts a 20MP Four Thirds CMOS sensor (17.4 x 13 mm) with modern back-illuminated tech, coupled with dual TruePic VIII processors. This combination delivers excellent dynamic range, low noise at high ISO, and sharp details - especially when paired with Olympus’ state-of-the-art in-body 5-axis image stabilization.

The Sony W310 has a diminutive 1/2.3" CCD sensor (6.17 x 4.55mm) clocking in at 12MP with a 5.8x lens crop factor. Despite the included sensor-shift image stabilization, the tiny sensor size limits overall image quality, especially in low light - expect significant noise and detail loss above ISO 400.

In testing, the E-M1X’s RAW files reveal punchier colors, better highlight roll-off, and 4x better than Sony’s at ISO 1600 and above. The Sony’s JPEGs look fine in bright daylight but rapidly degrade in shadows or indoor settings.

For anyone who cares about image quality - and wants the ultimate file flexibility with RAW - the Olympus is in a different league.

Autofocus Performance: Lightning-Fast Pro Tracking vs Basic Contrast-Detection

Autofocus can make or break an experience, especially for fast-paced shooting genres like wildlife, sports, or street.

The Olympus deploys a hybrid AF system with 121 focus points covering a wide area, including phase-detection and contrast methods, coupled with face and eye-detection AF. While it lacks animal eye AF (introduced in later models), the tracking is rock-solid and fast, tackling erratic subjects with minimal fuss.

The Sony W310 uses contrast-detection AF with only 9 focus points and no eye detection - fine for snapshots and static subjects, but hopeless for demanding tracking. Continuous AF and burst capabilities are non-existent, so forget about action photography.

As a guy who's chased birds around forest edges and shot hockey games, Olympus’s autofocus is a lifesaver. Sony’s AF system is too basic to be beyond casual snapshots.

Burst Speed and Buffer: Catching the Action, or Missing It?

Burst shooting came up often in my tests. Olympus boasts an astonishing 60 frames per second max burst rate (electronic shutter) and a beefy buffer, meaning you can lock in and nail that decisive moment on fast-moving subjects - key for wildlife and sports photographers.

Sony manages just 1 fps, which frankly means at best you get a single shot for each press of the shutter button. The buffer isn’t even relevant here.

Interestingly, Olympus’s pro-speed shooting capabilities consistently impressed me under real-world pressure. If you’re shooting high-speed sports, events, or wildlife - with split-second moments - E-M1X is unquestionably superior.

Lens Ecosystem and Compatibility: Versatility Meets Convenience

Olympus uses the Micro Four Thirds mount, giving access to over 100 lenses - from fast primes to ultra-zoom wildlife telephotos. This ecosystem is mature, versatile, and features third-party support from Panasonic, Sigma, and others.

Sony’s W310, being a fixed-lens compact, offers no lens-swapping. Its 28-112mm (35mm eq.) f/3.0-5.8 zoom is decent for travel and casual snaps but limited.

Over the years, I've tested countless MFT lenses with Olympus bodies, and this system stands out for balanced size, quality, and price. You get pro-grade glass without hauling around full-frame behemoths.

Battery Life & Storage: Marathon Shooter vs Snapshot Machine

Olympus’s built-in battery delivers a very respectable 870 shots per charge, which is impressive for such performance-heavy gear. Dual SD card slots provide redundancy and ample storage, critical for professional workflows.

Sony W310 relies on smaller batteries (NP-BN1) with unknown endurance but expectedly fewer shots per charge given the compact size. It has one card slot supporting SD and Sony’s proprietary Memory Sticks.

In testing, I frequently ended my Olympus days without needing a battery swap, even with heavy use of electronic viewfinder and burst shooting. Sony users may find themselves charging more often.

Weather Sealing and Durability: Ready for the Elements or Delicate Trinket?

Olympus E-M1X is built with professional durability in mind - environmentally sealed against dust and moisture (though not fully waterproof). Magnesium alloy body and weather resistance make it an ideal companion for landscape shooters lugging their gear through rain or snow.

Sony W310 is a delicate ultracompact bereft of any weather sealing. Treat it gently, keep it in your pocket or bag, and it’ll survive casual use.

For shooters who want gear that endures rugged conditions, Olympus is your workhorse. The Sony is better-suited to urban environments and family vacations where it doubles as a throw-in-the-pocket shooter.
