First Impressions: Style, Size, and Controls

The Olympus E-P5 and Sony W310 couldn’t look or feel more different at first glance. The E-P5 is a thoughtfully designed rangefinder-style mirrorless, while the W310 embraces ultra-compact hospitality.

Olympus E-P5: At 122x69x37 mm and 420g, the E-P5 strikes a balance - it’s portable yet substantial enough to inspire confidence in grip and control. When I first held it, its retro design mixed with modern materials felt akin to holding a cherished tool crafted for serious photography. The solid metal body feels premium, and the ergonomics immediately signaled to me that it was designed for extended use.

Sony W310: By comparison, the W310 is downright petite at 95x55x19 mm and just 137g. It slips into a jacket pocket and disappears in your hand, making it the quintessential “grab and go” camera. However, the plastic construction and minimal heft signal a device meant more for ease than for artistic ambition.

Controls tell another story. The E-P5 boasts dedicated exposure dials, customizable buttons, and a tilting touchscreen, providing tactile feedback and quick access. The W310 is a simplified affair - just a few buttons, no manual exposure modes, no touchscreen. As someone who values customizable controls and tactile maneuverability, the E-P5 instantly felt like a creative partner, while the W310 felt like a casual snapshot companion.

Sensor and Image Quality: The Heart of the Matter

When it comes to photography, sensor technology often makes or breaks the creative potential. Understanding the difference between these sensors is crucial before exploring performance in different discipline contexts.

Olympus E-P5 Sensor

• Type: Four Thirds CMOS sensor
• Size: 17.3x13 mm (224.9 mm²)
• Resolution: 16 MP (4608x3456)
• ISO Range: 100 - 25600 native
• Raw Support: Yes

The E-P5’s sensor offers a solid balance between resolution and noise control for its class. With 16 megapixels on a Four Thirds sensor, it isn’t just about resolution - it’s about high signal-to-noise ratio and dynamic range. Olympus also employs an anti-aliasing filter, balancing detail preservation against moiré. The ability to shoot raw facilitates expansive post-processing latitude, crucial for pro workflows.

Sony W310 Sensor

• Type: 1/2.3” CCD sensor
• Size: 6.17x4.55mm (28.07 mm²)
• Resolution: 12 MP (4000x3000)
• ISO Range: 100 - 3200
• Raw Support: No

The W310’s sensor is considerably smaller and uses CCD technology, which by the early 2010s had generally been supplanted by CMOS in enthusiast cameras. The smaller size impacts noise levels, low-light performance, and dynamic range. Its absence of raw support further limits flexibility, confining users to JPEG compression and in-camera processing.

Real-World Implications
During my controlled tests, images from the E-P5 consistently demonstrated superior detail retention, accurate color rendition across challenging lighting scenarios, and impressive dynamic range, especially in landscape and portrait lighting. Shadow recovery during raw development was particularly pleasing. In contrast, W310 files showed more noise at ISO 800 and above, softer detail especially when zoomed in, and lower tonal gradation on sunny highlights or shadowed areas.

So, for photographers prioritizing image quality - including ambitious amateurs and professionals - the E-P5 is the clear winner here.

Display and Viewfinding: Framing Your Creativity

LCD screens and viewfinder quality are often overlooked but critical usability factors. They can make photography a joy or a chore, especially in harsh lighting or fast-shooting scenarios.

The Olympus E-P5 features a 3-inch tilting capacitive touchscreen with 1037k dots, which I found to be crisp, bright, and responsive. The tilt mechanism is especially handy when shooting low to the ground or above crowds - for example, when capturing children’s portraits or vibrant street scenes. Touch-to-focus combined with traditional dials provided seamless hybrid operation, allowing me to switch shooting styles without breaking rhythm.

The Sony W310 has a smaller and fixed 2.7-inch LCD with just 230k dots. The lower resolution made image review less gratifying. In bright outdoor conditions, the screen was more prone to reflections, and lack of a viewfinder (optical or electronic) meant composing outdoors could be challenging, increasing reliance on the LCD alone.

Due to the absence of a built-in viewfinder on both, I often found myself wishing for at least an electronic VF on the E-P5, but it does support an optional accessory EVF for serious users.

Autofocus Systems Put to the Test

Autofocus ability is a critical metric, especially for fast action, wildlife, or portrait work where capture timing determines success.

Olympus E-P5

• Hybrid contrast-detection AF with 35 focus points
• Face detection and live view AF
• Continuous AF and tracking available

Sony W310

• Contrast-detection AF with 9 focus points
• No face/eye detection
• Single-shot AF; no continuous or tracking

While the numbers suggest a clear disparity, the practical difference is eye-opening. I tested AF speed on moving subjects for wildlife and sports scenarios and found the E-P5’s system markedly faster, more reliable, and more precise in locking focus under diverse lighting. Its face detection was dependable during portrait shoots, capturing crisp focus even when subjects moved naturally.

The W310’s AF struggled in low light and slower moving subjects - fine for casual walk-around shooting but frustrating for ambitious users. Limited focus points made selective focusing tricky, noticeably decreasing compositional flexibility.

Exploring Across Photography Genres

Let’s dive into how these cameras perform across the major photography categories - emphasizing practical usage and creative results.

Portrait Photography: Skin Tones and Bokeh

Portrait photographers demand accurate skin tone reproduction and pleasing background separation.

The E-P5’s Four Thirds sensor combined with its Micro Four Thirds lenses provided creamy bokeh, thanks to the lens aperture options and sensor size. Eye detection AF made capturing sharp eyes straightforward. During several portrait sessions, I found skin tones natural and well-rendered in various lighting, as well as flattering skin detail.

The Sony W310’s smaller sensor and fixed lens aperture (F3.0-5.8) yielded flatter depth-of-field and less background separation, making portraits appear more snapshot-like. Lack of face detection can cause missed focus on eyes, a dealbreaker for detailed portraits.

Landscape Photography: Dynamic Range and Detail

Landscape photography tests dynamic range and resolution.

The E-P5 delivered detailed images with strong dynamic range, retaining highlight and shadow details even during harsh midday sun. File flexibility via raw processing enables fine tonal adjustments that landscape photographers commonly require.

The W310’s limited dynamic range and excluding raw mode restrict editing latitude. Images tended to clip highlights or flatten shadows in complex landscape scenes.

Wildlife and Sports Photography: Autofocus, Burst Rates, and Speed

The Olympus E-P5’s 9 fps burst, coupled with better AF tracking, aided capturing fast action, even though the Four Thirds sensor’s crop factor (2.1x) means reaching far wildlife subjects requires telephoto lenses. Meanwhile, the W310 offers just a 1 fps burst, effectively limiting it to candid moments rather than serious action photography.

Street and Travel Photography: Discretion, Portability, and Versatility

Sony’s W310 ultra-compact size excels for discrete street shooting and travel scenarios where minimal gear is preferred. It fits comfortably in pockets and can be pulled out in a flash.

The E-P5, while larger, remains compact by mirrorless standards. Its sturdy build and comprehensive control layout favor users wanting one camera to do it all - from street to portraits to landscapes.

Considering battery life - the E-P5 yields around 330 shots per charge, enough for a day’s excursion with spare batteries. The W310’s smaller battery and older tech limit prolonged outings.

Macro and Night Photography

Macro capability on the E-P5 benefits from compatible lenses offering excellent close-focusing and stabilization, while the W310’s minimum 5cm macro focus is fine for casual snaps but lacks precision.

In low-light or astrophotography, the E-P5’s higher ISO capability (up to 25,600) combined with sensor stabilization yields more usable shots. The W310’s maximum ISO 3200 and CMOS sensor yield noisy images.

Video Capabilities: A Subtle but Important Consideration

The Olympus E-P5 records Full HD 1080p video at 30fps in H.264 format. It offers tilting screen advantages, sensor-based 5-axis stabilization (helpful for handheld clips), and built-in stereo mic options. It doesn’t offer microphone input or headphone monitoring, limiting professional video users but sufficient for casual videographers.

The Sony W310 tops out at simple VGA video (640x480 @30fps) in Motion JPEG format. This is inadequate for modern video needs beyond fun family videos or snapshots.

Build Quality, Weather Sealing, and Durability

Neither camera is weather sealed or ruggedized. The E-P5’s metal and high-quality construction make it more resilient to daily wear, while the W310’s plastic body is more vulnerable to shocks and drops. Those anticipating tough environments should consider this carefully.

Lenses, Storage, and Connectivity

Olympus E-P5 uses the Micro Four Thirds mount, supported by over 100 lenses from Olympus and third parties - from wide-angle primes to super-telephotos and specialty optics. This lens ecosystem is a major asset for creative photographers wanting versatility.

The Sony W310 is fixed-lens, limiting its optical flexibility.

Regarding storage, both use SD cards with the E-P5 supporting the newer SDXC standard for larger capacities. Connectivity-wise, the E-P5 includes built-in Wi-Fi for image transfer and remote shooting. The W310 lacks wireless features entirely.

Price and Value: Investment and Target User

Currently, the Olympus E-P5 may still be found used or at discounted rates around $400, which reflects its enthusiast-grade feature set and imaging potential. The Sony W310, often available under $150, remains a straightforward budget-friendly compact.

Your choice shifts dramatically depending on priorities. The E-P5 demands a more serious photographer willing to invest time and money in lenses and accessories, while the W310 might suit casual recorders wanting simplicity.
