Olympus E-M10 III vs Panasonic FS15: An Expert’s Take on Two Cameras from Two Worlds

When I first set out to compare the Olympus OM-D E-M10 Mark III and the Panasonic Lumix DMC-FS15, I chuckled a little to myself. On paper, they’re worlds apart - the E-M10 III is an entry-level mirrorless camera debuting in 2017, while the FS15 is a basic ultra-compact from way back in 2009. That’s a full eight years between them - eternity in camera tech terms.

But you’d be surprised how diving deep into these cameras unveils fascinating nuances about how technology and photography habits have evolved. Whether you’re a beginner hunting for a budget-friendly snapshooter or a seasoned enthusiast looking for the perfect travel companion, this detailed hands-on comparison aims to clarify which camera ticks the boxes - and more importantly, why.

Holding Them in Your Hands: Ergonomics and Build

Jumping in, one of the most immediate impressions you get is the size and feel. The Olympus E-M10 III sports the classic SLR-style mirrorless design, compact but solid, while the Panasonic FS15 is a pocket-sized, no-frills ultracompact.

The E-M10 III weighs about 410 grams with dimensions 122x84x50mm - it feels reassuringly substantial without clunkiness. Its grip is pronounced enough for steady shooting, crucial when you shoot handheld landscapes or portraits over extended periods. Meanwhile, the FS15 is feather-light at 136 grams, measuring a slim 97x54x22mm, perfect for sliding into a jacket pocket or purse.

I found the E-M10 III’s robust build significantly more comfortable when shooting for hours or navigating manual controls. Plus, it’s well-suited for colder or wetter conditions with its durable design (although not fully weather-sealed). The FS15, as an ultracompact, sacrifices grip comfort for ultimate portability, which can lead to some camera shake in certain situations.

So, if size and handling are big factors - whether because of weather, hand size, or the length of your shoot - the Olympus takes a clear lead here.

First Impressions from Above: Control Layout and Usability

Picking up each camera and exploring the controls reveals their differing philosophies. The Olympus is designed for active photographers who want to tinker with settings; the Panasonic aims for simplicity.

The E-M10 III’s top plate houses a mode dial with priority and manual modes, a dedicated exposure compensation dial, and ergonomically placed shutter and control buttons. This layout lets you tweak exposure, ISO, and autofocus modes rapidly without diving into menus - a boon when timing matters in wildlife or sports shooting.

By contrast, the FS15 offers limited physical controls - no manual exposure options, no external dials for shutter priority or aperture. Everything is done mostly via menu navigation on its fixed screen. For street shooters or casual users, this might be less intimidating, but for anyone wanting creative control, it feels a bit like trying to build a sandcastle with mittens on.

Sensor Specs and Image Quality: The Heart of the Matter

One of the largest divides between these cameras is their sensor technology - a fundamental determinant of image quality.

The E-M10 III sports a 16-megapixel Four Thirds CMOS sensor measuring 17.4 x 13 mm with a sensor area of 226.2 mm². It’s paired with Olympus’s TruePic VIII processor. The efficient size-to-performance ratio yields crisp 4608x3456 images with a good dynamic range and decent high ISO noise control up to ISO 25600 (though rarely practical at the top end, it’s nice to have the headroom).

In contrast, the Panasonic FS15 uses a much smaller 1/2.3" CCD sensor (6.08x4.56 mm, 27.72 mm²) offering 12 megapixels at 4000x3000 resolution. While it was adequate for casual snapshots in 2009, its tiny size severely limits dynamic range and low-light performance by today’s standards.

From my practical testing, the Olympus consistently renders finer detail, smoother gradations, and richer colors, especially in challenging lighting. The Panasonic squashes shadows and struggles with noise beyond ISO 400. Not to mention, CCD sensors typically can’t match the high ISO fidelity of later CMOS designs.

The View You Need: LCD Screens and Viewfinders Compared

No photographer wants to struggle framing shots or navigating settings, so display quality is key.

The E-M10 III’s 3-inch, 1.04-million-dot tilting touchscreen makes composition flexible and intuitive; touch to focus is responsive and a pleasure during macro or awkward angles. The electronic viewfinder (EVF) with 2.36 million dots and full 100% coverage offers a bright, lag-free preview - essential for working in bright outdoor conditions or fast action.

Meanwhile, the FS15’s fixed 2.7-inch, low-res 230,000-dot LCD feels cramped and subpar by modern standards. No EVF on board means you’re forced to compose with an LCD that’s tough to see in bright sunlight. Moreover, no touchscreen means slower menu navigation.

So for framing flexibility and user interface convenience, the Olympus smokes the Panasonic.

Autofocus Systems and Speed: Catching the Decisive Moment

Performance-wise, autofocus is a key area where these cameras diverge significantly - especially important for wildlife, sports, and street shooters.

The Olympus features a contrast-detect AF system boasting 121 focus points (with face detection), continuous tracking autofocus, and a maximum burst rate of 8.6 frames per second. This combination gives you confidence in capturing sharp images of moving subjects, from kids on a bike to birds in flight.

The FS15 has a much simpler contrast detect AF system with 11 zones and no tracking or face detection. The continuous shoot speed is a sluggish 2 fps, which pretty much restricts you to posed or slow-moving subjects.

In my experience, the E-M10 III nails focus quickly and accurately in diverse lighting, while the FS15 requires patience and sometimes manual adjustments for anything beyond casual snapshots.

Portraits exhibit the Olympus’s superior skin tone rendering and smoother bokeh, thanks to lens options and sensor size. In landscapes, the dynamic range and detail from the E-M10 III are noticeably better. Night shots expose the FS15’s struggles with noise and limited exposure versatility.

Shooting Across Genres: Which Camera Shines Where?

Now, let’s break down performance by photography type - because your priorities here might differ wildly.

Portrait Photography

The Olympus’s larger sensor and Micro Four Thirds (MFT) lens ecosystem let you create pleasant subject separation with creamy bokeh - crucial for flattering portraits. Eye-detection autofocus, though not state-of-the-art, helps lock sharp focus on faces. The Panasonic is limited to its fixed zoom’s mid-range aperture (f/3.3-5.9), producing flatter images overall.

Olympus for portraits, no contest.

Landscape Photography

With higher resolution, better dynamic range, and weather-sealed body (albeit not fully professional-grade), the E-M10 III wins for landscapes. The Panasonic’s small sensor restricts sharpness and exposure latitude.

E-M10 III is the clear landscape champion.

Wildlife and Sports Photography

Tracking autofocus, fast burst rates, and adaptable lenses let the Olympus capture action with agility. The FS15 is better suited for static subjects.

Street Photography

This is where things get interesting. The FS15’s tiny size and unobtrusiveness make it a stealthy street shooter in crowded cityscapes. The Olympus, though compact compared to DSLRs, is bulkier and louder.

Macro Photography

Olympus benefits from focusing precision and in-body 5-axis stabilization - great for detailed close-ups. The Panasonic, while offering 5 cm macro from its fixed lens, lacks sophisticated focusing aids or stabilization.

Night and Astro Photography

The E-M10 III’s higher ISO capabilities, longer shutter options (up to 60 seconds), and in-body stabilization enable more successful nightscape shots. The FS15’s ISO ceiling and slow shutter max of 2 seconds limit creative freedom here.

Video Capabilities

The Olympus shoots impressive 4K video at 30fps, recording in efficient H.264 codec with decent in-camera stabilization. The FS15 maxes out at 640x480 standard definition; practically obsolete for today’s video demands.

Travel Photography

While the Olympus isn’t pocketable, its versatile feature set and battery life (~330 shots per charge) make it a solid travel companion. The FS15’s ultra-compact size shines when ultimate portability is your only priority.

Professional Work

The Olympus supports raw capture, offers detailed custom white balance, in-body image stabilization, and a better lens ecosystem suited for workflow integration. The Panasonic is geared more to casual hobbyists without pro ambitions.

Toughness and Reliability: Built to Last?

Neither camera is ruggedized for extreme weather, but Olympus uses more durable materials and offers better environmental sealing - something I appreciate when shooting outdoors.

Behind the Lens: Lens Ecosystem and Compatibility

Arguably one of Olympus’s biggest strengths is compatibility with 107 Micro Four Thirds lenses ranging from ultra-wide primes to super telephotos, macro optics, and options for stabilization. This ecosystem is battle-tested and supported by multiple manufacturers (Panasonic, Sigma, Tamron).

The FS15’s fixed lens (29-145 mm equivalent with f/3.3-5.9 aperture) offers no interchangeability. This limitation restricts creative growth, though it simplifies the learning curve for beginners.

Powering Through: Battery and Storage

Olympus uses a BLS-50 lithium-ion battery rated for about 330 shots per charge, quite reasonable for mirrorless in this class. The Panasonic’s battery specs are barely documented, but ultracompacts like the FS15 typically offer shorter usage times due to smaller cells.

Both cameras utilize standard SD/SDHC storage, but the Olympus supports UHS-I/II cards for faster writing - important for continuous shooting and video.

Connectivity and Extras

Built-in wireless on the Olympus lets you transfer images to smartphones and control the camera remotely, a godsend for modern workflows. The Panasonic offers none of these wireless bells and whistles.

The Olympus has HDMI output, a USB 2.0 port for tethering and charging, but no headphone or mic jacks. The FS15 includes HDMI but lacks any external audio or wireless options.

When Price Meets Performance: Value Breakdown

Here’s where the story folds into pragmatic territory. The Olympus E-M10 III retails around $650 - fairly priced given its sophisticated sensor, excellent image quality, and versatility. The Panasonic FS15 lists at around $180 new (or can be found used cheaper).

Frankly, the Panasonic is best seen as a budget point-and-shoot for casual shooting with zero fuss - a small, pocketable companion for daylight snaps. The Olympus is an investment in image quality and creative growth, appealing to beginners willing to learn and enthusiasts desiring portability without compromise.
