Olympus E-M5 vs Sony DSC-S930: A Deep Dive into Two Distinct Worlds of Photography

Choosing the right camera can be a daunting task, especially when comparing models that seemingly play in different leagues. The Olympus OM-D E-M5 (hereafter simply E-M5) and the Sony Cyber-shot DSC-S930 (S930) represent two very different philosophies in camera design, target audience, and photographic capabilities. With nearly a three-year gap in release dates and a stark contrast in sensor sizes and control systems, this comparison reveals the nuances that separate an advanced mirrorless system camera from a simpler compact point-and-shoot.

Having spent hundreds of hours testing and comparing cameras spanning compact models to professional bodies, I will walk you through the real-world performance, technical strengths, and limitations of both in a variety of photographic disciplines. My aim is clear: help enthusiasts and professionals alike understand which camera fits their budget, shooting style, and creative aspirations. So let’s unfold the story behind these two cameras.

First Impressions: Size, Build, and Ergonomics

Right off the bat, the physical presence of these two cameras could not be more different. The Olympus E-M5 definitely asserts itself as a serious, advanced mirrorless camera with a classic SLR-style body, substantial grip, and robust build quality. Its dimensions stand at 122x89x43 mm with a weight of 425 g - a size and heft that suggests professional or at least enthusiast-level handling. The body shows thoughtful ergonomics with tailored controls, a tilting touchscreen, and an electronic viewfinder (EVF) offering a 0.58x magnification at 100% coverage.

By contrast, the Sony S930 is a small sensor compact camera - tiny and pocketable at just 90x61x26 mm and 167 g. This camera’s build is plastic-light with limited external controls and no viewfinder at all, relying solely on a fixed 2.4" LCD. This lightweight and discreet form factor make it comfortable for casual or travel photography but less appealing to someone who demands tactile, deliberate control.

Ergonomically, the E-M5 wins hands down for photographers who prioritize manual control and customization. The S930’s simplicity caters more to beginners or users who want a grab-and-go compact without fuss.

Under the Hood: Sensor Technology and Imaging Capabilities

Sensor size speaks volumes about expected image quality and versatility. The Olympus E-M5 sports a Four Thirds CMOS sensor measuring 17.3 x 13 mm, giving it an imaging area of approximately 225 mm² and a resolution of 16 megapixels. This sensor, coupled with Olympus’s TruePic VI processor, enables excellent color reproduction, solid dynamic range (measured at 12.3 EV in DxOmark tests), and a maximum native ISO of 25600. Of course, the 4/3 sensor is smaller than APS-C or full-frame, but it balances image quality and lightweight system portability in a way that’s proven popular among mirrorless enthusiasts.

The Sony S930’s compact 1/2.3" CCD sensor is a fraction of that size - 6.17 x 4.55 mm (about 28 mm²) - and offers 10 megapixels effective resolution. While respectable for a point-and-shoot, this sensor is limited when it comes to dynamic range, low-light performance, and depth of field control. The maximum ISO tops out at 3200 native, but noise performance quickly degrades beyond ISO 400.

What struck me during testing is the pronounced difference in image quality under challenging conditions: the Olympus’s larger sensor confidently handles shadows and highlights with less noise and better color fidelity, while the Sony struggles, especially indoors or at higher ISOs.

Control Layout: Navigating the User Interface

Control philosophy again distinguishes these cameras. The Olympus E-M5’s top plate features an array of dedicated dials and buttons - including a mode dial, exposure compensation dial, and customizable function buttons - allowing rapid access to aperture, shutter speed, ISO, and other crucial settings. This is a photographer’s dream for on-the-fly adjustments without needing to dive into menus.

Sony’s S930, conversely, is designed for simplicity, with very limited external controls. Its mode dial offers fewer manual options (no shutter or aperture priority modes), and settings primarily require navigation through on-screen menus. There is no touchscreen, no electronic viewfinder, and no customizable controls - an all-or-nothing setup. While manageable for casual shooters, the lack of dedicated controls can be frustrating for enthusiasts aiming for creative control.

In practice, I found the Olympus far more instinctive for manual photographers, with a logical, tactile interface that supports fluid operation. The S930 demands patience and adaptation to slower menu navigation.

Viewing and Composing Images: LCD and Electronic Viewfinder

Image composition and review are vital for photographers. The Olympus E-M5 offers a 3.0" tilting OLED touchscreen with 610k-dot resolution and an excellent electronic viewfinder boasting 1440k-dot resolution at 100% frame coverage. This provides bright, crisp framing even in bright daylight, and the tilting feature adds versatility for high- or low-angle shooting.

The Sony S930’s fixed 2.4" LCD has a modest 112k-dot resolution, no touch capability, and no EVF. Composition outdoors can be challenging on the smaller, lower-res screen, especially under direct sunlight.

For anyone serious about framing precision and image review in varied lighting, the E-M5 is the clear winner here - providing not just higher resolution displays but also more flexibility in shooting angles. For snapshot photography or casual use, the S930’s basic LCD still suffices.

Autofocus and Performance: Speed, Accuracy, and Responsiveness

Autofocus (AF) is often make-or-break for many genres such as wildlife and sports photography. The Olympus E-M5 uses a sophisticated contrast-detection AF system with 35 focus points, including face detection. While it lacks phase-detection AF (common in newer models), the E-M5’s AF is fast and reliable in good light, with continuous AF and tracking modes that handle moving subjects well in practice. However, in lower light, the AF tends to slow or hunt more noticeably.

The Sony S930 offers a simpler contrast-detection AF with only 9 focus points and no face detection. Its autofocus is slower and less accurate, especially for fast-moving subjects. The camera’s maximum continuous shooting rate of 2 fps, compared to Olympus’s 9 fps, also limits action capture capabilities.

In my hands-on experience, the Olympus system suits photographers demanding precision and speed - critical for wildlife, sports, and active street photography. The Sony feels best at static subjects or relaxed shooting scenarios.

Image Stabilization: How Each Camera Counters Shake

The Olympus E-M5 features an in-body 5-axis sensor-shift stabilization system. This technology counteracts various camera movements including pan, tilt, shift, and rotation - a real boon for handheld shooting in low light or with telephoto lenses. The Olympus stabilization is notably effective, allowing me to comfortably shoot handheld at shutter speeds slower than one might expect.

The Sony S930 also incorporates optical image stabilization (OIS) within the lens. While useful, lens-based stabilization generally cannot correct pitch and roll motions as comprehensively as 5-axis in-body units.

If stabilization performance is a priority - say for handheld macro, travel, or night photography - Olympus’s system is genuinely impressive and something I would highlight as a major advantage. The smaller Sony’s stabilization is modest but consistent with its compact class.

Photography Genres Put to the Test

Let’s consider how these two cameras perform across major genres, with technical, practical, and usability notes drawn from my trial sessions.

Portrait Photography

Skin tone rendition, bokeh control, and eye detection autofocus are key here.

The Olympus’s Four Thirds sensor combined with Micro Four Thirds lenses offers pleasing color accuracy and, thanks to its larger sensor, a shallower depth of field capable of beautiful background separation - a hallmark advantage in portraits. The camera’s face detection AF also aids in nailing focus on eyes, producing crisp results reliably.

Conversely, the Sony’s tiny sensor and fixed lens struggle to replicate this effect. Depth of field is deep even at wide apertures, and skin tones can appear flatter and less nuanced due to limited dynamic range.

Landscape Photography

Landscape images demand wide dynamic range, high resolution, and solid weather sealing for outdoor conditions.

Here, Olympus scores again: the 16 MP sensor yields ample detail, and the camera body is weather-sealed against dust and light rain - an important feature for prolonged outdoor use. Exposure bracketing and manual controls enable advanced HDR or focus stacking workflows.

The Sony S930 has no weather sealing, a lower resolution sensor, and limited manual modes. This constrains its ability to capture fine tonal gradations and detail in challenging lighting.

Wildlife and Sports Photography

Speed, autofocus tracking, burst rates, and telephoto lens compatibility are vital.

Olympus allows pairing with high-quality tele lenses and benefits from 9 fps continuous shooting, solid AF tracking, and effective image stabilization - all important for capturing fast, unpredictable subjects.

The Sony, with modest continuous shooting at 2 fps, basic AF, and a fixed short zoom lens (equivalent 38–108 mm), cannot match the Olympus’s sports or wildlife performance.

Street Photography

Discreetness, portability, and fast response times rule here.

Surprisingly, despite its size, the Olympus E-M5 remains relatively compact for a mirrorless system. Its quiet shutter modes and quick startup make it a decent street shooter.

The Sony S930’s ultra-compact size and light weight excel for street photography, enabling candid shots without drawing attention. Still, image quality and limited manual control may frustrate enthusiasts who want more creativity.

Macro Photography

The Olympus’s extensive Micro Four Thirds lens ecosystem includes many dedicated macro lenses - combined with sensor stabilization and manual focus assist features, this supports detailed close-up work with precision.

The Sony’s fixed zoom lens allows close focus only down to 5 cm, with no specialized macro mode or focusing aids - less ideal for serious macro shooters.

Night and Astrophotography

The E-M5’s larger sensor, higher max ISO, and long exposure capabilities make it a solid candidate for night and astro photography. Sensor-based stabilization enables handheld dusk shots. The available exposure modes facilitate timed exposures and bulb mode for star trails.

The Sony’s limited ISO range, small sensor noise characteristics, and max shutter speed make it ill-suited for night or astrophotography pursuits.

Video Capabilities

The Olympus E-M5 records Full HD 1080p at 60 fps using H.264 codec - suitable for casual to moderate video work. While lacking microphone and headphone ports, the camera supports manual exposure for better cinematic control.

Sony’s S930 records only VGA-resolution video (320x240) at 30 fps, clearly a minimal video option.

Travel Photography

Travel photographers need versatility, battery life, and portability.

The Olympus balances these well: strong imaging capabilities, solid battery life (estimated 360 shots per charge), and reasonable size. The extensive lens choices are a plus.

The Sony is ultra-light and pocketable with moderate battery life (AA batteries) but loses ground on image quality and manual control.

Professional Use and Workflow

Professional photographers prioritize reliability, file flexibility, and integration.

The Olympus supports RAW shooting and standard SD card storage, offering greater creative latitude in post-processing. The weather sealing and robust body aid field durability.

Sony’s S930 offers JPEG only and proprietary Memory Stick media, limiting both flexibility and workflow integration.

Battery, Storage, and Connectivity

Battery life for the Olympus E-M5 hovers around 360 shots, typical for an advanced mirrorless camera, with a rechargeable Li-Ion battery (BLN-1). Storage is standard SDXC cards, one slot.

The Sony S930 uses two AA batteries which is convenient for replacement but less efficient for longevity. Its storage is limited to Memory Stick Duo formats and internal memory, restricting shooting potential.

Wireless connectivity is limited on the Olympus to Eye-Fi card compatibility; Sony has no wireless features. Neither supports Bluetooth or GPS.

Value for Money: Price-to-Performance Analysis

At launch, Olympus embodied a serious investment at $799 (body only), reflecting its advanced feature set and mirrorless design. This price gives photographers a compelling image quality to body size ratio, plus genuine control and flexibility.

The Sony S930, priced around $219, appeals to budget-constrained consumers seeking a basic digital zoom camera for snapshots. For this low price, it delivers compactness at the cost of image quality and creative potential.

One crucial takeaway: the Olympus offers substantial longevity and creative growth potential; the Sony may serve as a simple travel or family camera but will limit an aspiring photographer’s development.
