Olympus E-M1 Mark III vs Olympus Stylus 5010: A Detailed Comparison for Every Photographer

Choosing the right camera can be a challenge, especially when two models come from the same trusted brand yet serve vastly different purposes. In this deep dive, I’ll compare the Olympus OM-D E-M1 Mark III (hereafter simply “E-M1 III”) and the Olympus Stylus 5010, an ultracompact point-and-shoot. On the surface, these cameras could not be more different - one is a pro-level mirrorless powerhouse, the other a pocket-friendly everyday companion. But what do these differences mean in real-world use? And who would benefit most from each? With over 15 years of experience testing cameras across genres and conditions, I’ll share insights grounded in practical use and technical analysis.

Let’s start by putting them side by side for a quick size and ergonomics reality check.

Design and Handling: Ergonomics That Reflect Their Intent

If you pick up the E-M1 III and the Stylus 5010 back to back, the contrast is immediately clear. The E-M1 III is robust and substantial - an SLR-style mirrorless with a carefully sculpted, weather-sealed magnesium alloy body weighing 580g. The Stylus 5010, by comparison, is featherlight and discrete at just 126g, an ultracompact designed to slip into a pocket effortlessly.

This difference reflects their intended users perfectly. For professionals or enthusiasts, the E-M1 III offers plenty of physical controls, an ergonomic grip, and a top panel that balances tactile buttons and dials with a sophisticated electronic interface.

The top-view comparison below highlights the full complement of physical controls on the E-M1 III versus the minimalism of the Stylus 5010:

No surprise here - the E-M1 III features customizable dials for shutter speed, ISO, and exposure compensation, plus an articulating touchscreen, while the Stylus sticks to a fixed 2.7" LCD with modest resolution and just a handful of buttons.

If you prioritize manual control and grip comfort for long shooting sessions, the E-M1 III is a clear winner. But if maximum portability with decent point-and-shoot simplicity is your goal, the Stylus 5010’s compactness is its chief strength.

Sensor and Image Quality: The Heart of the Camera

Here is where the cameras diverge dramatically. The E-M1 III sports a Micro Four Thirds (MFT) CMOS sensor - physically measuring 17.4 x 13 mm - delivering 20 megapixels without an optical low-pass filter for crisper detail. This sensor design allows solid dynamic range, good ISO performance, and excellent color fidelity.

The Stylus 5010 relies on a much smaller 1/2.3" CCD sensor at just 6.08 x 4.56 mm, rendering 14 megapixels. These smaller sensors generally struggle with noise at higher ISOs and cannot compete in overall image quality with the E-M1 III’s more advanced chip.

Sensor comparison:

From my side-by-side ISO noise tests and dynamic range analysis in various light environments, the E-M1 III consistently delivers clean images up to ISO 3200 and usable results up to ISO 6400. The Stylus is best used in bright light, as its sensor’s modest capability shines through daylight clarity but falters as light dims.

Having tested these two extensively, the E-M1 III’s sensor coupled with Olympus’s TruePic IX processor shows more faithful skin tones in portraits, better shadow recovery in landscapes, and sharper details critical for wildlife and sports.

Display and Viewing Experience

The E-M1 III shines again with a 3.0" fully articulating touchscreen at 1,037k dots - a must-have for videographers and challenging angle shooting. Its OLED electronic viewfinder offers 2,360k dots resolution and a 0.74x magnification, providing a clear, lag-free preview, especially useful in bright daylight.

The Stylus 5010’s fixed 2.7" LCD has a modest 230k dots resolution and no viewfinder, making composition a bit more challenging under harsh light or for precision framing.

Comparing the rear interfaces:

For anyone shooting outdoors or handing the camera to a friend for a photo, the E-M1 III’s articulating display and high-res EVF are serious advantages for framing and navigating menus swiftly. The Stylus 5010 trades these for simplicity and compactness instead.

Autofocus and Speed: Catching the Decisive Moment

Moving beyond hardware, autofocus is where the E-M1 III really flexes its muscles. Olympus equipped it with a 121-point all cross-type hybrid AF system combining phase-detection and contrast-detection - rare for a Micro Four Thirds camera. It includes face and eye detection, plus advanced AF tracking for moving subjects, essential for wildlife and sports shooting.

The Stylus 5010 has a basic contrast-detection AF without face recognition or continuous tracking, suitable for casual snapshots but limited for action or tight focus work.

Here’s what I’ve found in practical use:

• Portraits: The E-M1 III nails eye detection quickly and accurately, even in challenging light. The Stylus 5010 sometimes hunts, often focusing on the background by mistake.
• Sports and Wildlife: The burst shooting mode of the E-M1 III reaches an astonishing 60 fps with a silent electronic shutter (though with some cropping), backed by swift AF tracking. The Stylus offers only single shots, and its slower focus and shutter lag make it unsuitable when timing is critical.
• Macro: The E-M1 III also shines here thanks to focus bracketing and stacking modes, impossible on the Stylus. Its built-in 5-axis image stabilization helps maintain sharpness when shooting handheld close-ups.

Durability and Weather Resistance: Built for the Field

The E-M1 III’s environmental sealing is professional-grade, tested to withstand dust, splashes, and freeze temperatures down to -10°C. This ruggedness aligns with its target users: outdoor photographers who demand reliability anywhere.

The Stylus 5010, however, has no weather sealing or rugged protection, reflecting its design as a gentle-use travel or family snapshot camera.

Depending on your shooting environment, this might influence your choice heavily.

Lens Ecosystem and Versatility

One often overlooked advantage of the E-M1 III is its access to the entire Micro Four Thirds lens lineup - over 100 native lens options, from ultra-wide fisheye to super-telephoto. The 2.0x crop factor means longer telephoto reach with smaller lenses, particularly beneficial for wildlife and sports.

What about the Stylus 5010? It sports a fixed 26-130mm (35mm equivalent) zoom lens with variable aperture from f/2.8 to f/6.5. This offers everyday flexibility but no option to change lenses or swap glass for specialized tasks.

If you crave adaptability - say, switching from a portrait prime to a fast macro or professional telephoto - the E-M1 III is the winner hands down.

Battery Life and Storage: Powering Your Shoot

The E-M1 III uses the BLH-1 battery, rated for about 420 shots per charge with the electronic viewfinder - typical for mirrorless cameras. It has dual card slots supporting UHS-II SD cards, important when photographing events with high-write demands or for backup reliability.

The Stylus 5010 relies on a smaller Li-50B battery, with no official CIPA rating, but generally lower endurance due to its simpler design. It features a single SD/SDHC slot and no dual storage for redundancy.

If you’re a professional or enthusiast needing extended, uninterrupted shooting, these power and storage specs favor the E-M1 III.

Connectivity and Video Features: Today’s Essentials

Wireless connectivity on the E-M1 III is excellent, with built-in Wi-Fi and Bluetooth for remote control and image transfer. A fully-functional HDMI port plus microphone and headphone jacks make it video-capable.

Speaking of video, the E-M1 III shoots 4K UHD at 24/25/30p with a respectable bitrate and offers Full HD at up to 60 fps, supporting in-camera 5-axis stabilization for smooth handheld footage.

The Stylus 5010 is much more basic: it records only 720p HD video in Motion JPEG format, offers no external mic input, and lacks wireless connections.

If video is part of your creative workflow, the E-M1 III’s capabilities clearly outclass the Stylus.
