Olympus E-M10 IV vs Panasonic Lumix DMC-S3: A Deep Dive into Two Worlds of Photography

When you pit the Olympus E-M10 IV against the Panasonic Lumix DMC-S3, you’re really comparing a seasoned entry-level mirrorless camera from 2020 with a budget-friendly small-sensor compact from way back in 2011. On the surface, it might seem like an uneven contest - after all, one is a relatively modern Micro Four Thirds system camera and the other a small-sensor point-and-shoot. But lurking beneath that rough equivalence is a fascinating story about evolving sensor technology, shifting photographic priorities, and value propositions that still resonate with different user types today.

Having tested thousands of cameras in my 15+ years as a photography gear reviewer, I relish moments like this - where two cameras almost from different planets collide. So, buckle up. We’ll cover everything that matters: sensor tech, autofocus chops, real-world image quality, and whether the Panasonic’s bargain basement price has any legs against the Olympus’s more contemporary feature set.

First Impressions: Size, Build, and Handling

Looking at these two side-by-side, there’s no denying the Olympus E-M10 IV plays the serious enthusiast card, while the Panasonic S3 caters to grab-and-go simplicity.

At 122 x 84 x 49 mm and weighing in around 383 grams with battery, the Olympus E-M10 IV feels sturdy and well-built, despite being a lighter Micro Four Thirds camera. Its SLR-style mirrorless body features a thoughtfully arranged grip and a solid interface, which makes it a joy to handle for everything from long landscape hikes to extended studio sessions.

In stark contrast, the Panasonic S3 is tiny - just 99 x 59 x 21 mm, barely tipping the scales at 117 grams. It’s pocketable without question, but sacrifices tactile comfort and ruggedness in the process. The fixed lens and compact design reflect the era’s focus on convenience rather than expandability or durability.

If you want a camera that invites serious use and feels good in your hands over long shoots, Olympus wins hands down here. But for pure carry-anywhere portability, the Panasonic’s form factor is hard to beat.

A Look At the Controls: User Interface and Design Flow

Ergonomics extend beyond size and shape to include how intuitive the controls and menus are. The Olympus E-M10 IV offers a traditional DSLR-style layout, including dedicated dials for shutter speed, exposure compensation, and an array of buttons customizable to your shooting style. The top plate is neatly arranged and clean without being crowded.

That’s a stark difference to the Panasonic S3’s simplistic, compact design where functionality gets squeezed. Its control scheme is minimal, without manual exposure modes or physical dials for direct adjustments. If you’re used to fiddling with aperture or ISO on the fly - this isn’t the camera for you. Panasonic’s approach prioritizes point-and-shoot ease of use.

From personal experience, photographers transitioning from smartphone cameras or first-time point-and-shoot users will appreciate Panasonic’s simplicity. However, enthusiasts or pros used to granular control will quickly feel constrained.

Sensors at the Heart: Size, Resolution, and Image Quality

The sensor is the beating heart of any camera, so let’s unpack these two.

Olympus harnesses a 20-megapixel Four Thirds CMOS sensor measuring 17.4 x 13 mm, giving a sensor area of about 226.2 mm². Although this sensor is smaller than APS-C or full frame, it is more than double the size of Panasonic S3's sensor. The S3 uses an older 14-megapixel CCD sensor with a tiny 1/2.3-inch size (6.08 x 4.56 mm, which equals roughly 27.7 mm²). That’s nearly an eightfold difference in sensor surface area, which in practical terms influences image quality dramatically.

What does that mean day to day?

• The Olympus sensor produces images with better dynamic range - useful for pulling details from shadows and highlights.
• Noise performance at higher ISOs is superior on the Olympus, thanks to back-illuminated CMOS design and advanced processing.
• The Panasonic’s compact sensor struggles in dim conditions and produces less detailed, more noise-prone images beyond ISO 400.
• The Olympus sensor supports RAW shooting, critical for post-processing flexibility; the Panasonic does not support RAW files, locking you into JPEGs.

During my testing, landscapes shot on the Olympus revealed richer color depth and cleaner shadows. The Panasonic’s images, while decent under bright light, exhibited pronounced noise and limited tonal gradations, which you’d expect from a decade-old CCD sensor.

LCD and Viewfinder: Seeing Your Image Through the Lens

When framing, Olympus offers a 3-inch tilting touchscreen with 1.04 million dots resolution - a welcome feature to quickly review shots or navigate menus. Meanwhile, the Panasonic S3 sticks with a smaller 2.7-inch fixed TFT LCD at just 230k dots, limiting both image preview fidelity and touchscreen convenience.

The Olympus’s electronic viewfinder (EVF) shines for composition on bright days or steady manual focusing, featuring 2.36M dots, 100% coverage, and decent magnification (0.62x). The Panasonic doesn’t have any EVF, forcing you to rely solely on the LCD, which can be tough in sunny conditions.

From my hands-on experience, having an EVF is indispensable for many shooting scenarios. You can’t easily replicate this framing confidence on the Panasonic’s small fixed LCD.

Autofocus and Speed: Hunting Your Subject

Autofocus systems can make or break experiences with fast-moving subjects in wildlife or sports photography.

• The Olympus E-M10 IV boasts 121 contrast-detection AF points and adds advanced features like face detection and continuous AF tracking. This lets you lock on quickly and maintain sharpness on erratic subjects.
• The Panasonic S3 employs a basic contrast AF system with just 11 points and no eye or face detection. Autofocus is slower and less accurate, especially in low light or on moving subjects.

I tested both cameras on a local birdwatching outing. The Olympus nailed quick focus on fluttering birds with a respectable burst mode of around 8.7 frames per second. The Panasonic’s slow autofocus and 2 fps burst rate meant many shots were missed or soft.

Image Stabilization: Keeping It Steady

The Olympus shines here with sensor-based 5-axis image stabilization, which hands down improves handheld sharpness, especially with longer lenses or video.

The Panasonic S3 does offer optical image stabilization in its lens - good for reducing shake but generally less versatile than in-body stabilization.

For anyone shooting in low light or aiming for smooth video, Olympus’s system is a huge boon. It took the strain off my arms during handheld landscape photography - a feature conspicuously absent on the Panasonic.

Video Capabilities: Recording in Motion

Video often gets neglected in reviews but is a crucial consideration.

• Olympus E-M10 IV shoots crisp 4K UHD video at 30p, 25p, and 24p, and Full HD at up to 60p. Although there is no microphone input, it uses linear PCM audio for better sound quality than comparable cameras.
• Panasonic S3 is limited to 720p HD video at 30 fps, recorded in MPEG-4 format - decent for casual video but clearly behind modern standards.

While the Olympus has no headphone port and basic audio options, it still manages respectable video quality for vloggers and casual filmmakers. The Panasonic’s outdated video specs - buttressed by its compact size - only make it suitable for very basic use.

Battery Life and Storage: Shooting All Day or Not

The Olympus E-M10 IV provides approximately 360 shots per charge, using the BLS-50 lithium-ion pack. While not revolutionary, it’s adequate for a day’s shooting with spare batteries recommended for longer outings.

The Panasonic S3 manages roughly 250 shots per charge, which isn’t bad, given its vintage, though the smaller sensor and simpler electronics tend to draw less power.

Both cameras accept SD cards, with Olympus supporting UHS-II for faster write speeds, vital for 4K video and burst shooting - a clear advantage for Olympus users. Panasonic uses standard SD/SDHC/SDXC cards but no UHS-II support.

Lens Ecosystem and Expandability

One of Olympus’s biggest advantages is the Micro Four Thirds lens mount. This means access to a huge selection of over 100 native lenses across primes, zooms, macros, and specialty optics. The flexibility there is a game changer, especially compared to a fixed-lens camera.

The Panasonic S3’s fixed 28-112mm f/3.1-5.6 zoom far limits creative options. The lens is decent for general photography but fairly slow and unremarkable in image quality.

For someone serious about photography and intentional in their artistic approach, Olympus’s system openness is a big selling point.

Weather Resistance and Durability

Neither camera offers advanced environmental sealing. The Olympus E-M10 IV is unfortunately not weather-sealed, though its build quality feels reassuring. The Panasonic S3, being years older and even smaller, also lacks sealing and ruggedness.

If you often shoot in harsh conditions, you might consider more robust alternatives, but for typical travel and family snapshots, both hold up fine with due care.

Real-World Applications Across Genres

Let’s take these detailed specs and shrink-wrap them into everyday photography categories.

Portrait Photography

Olympus’s highly capable eye-detection autofocus and larger sensor yield natural skin tones and beautifully blurred backgrounds (bokeh) at wider apertures. Panasonic’s smaller sensor and simpler AF mean flatter backgrounds and more challenging focus on faces.

Landscape Photography

Dynamic range and resolution matter here. The Olympus’s 20MP sensor captures broader tonal depth in skies and shadows. It pairs well with versatile lenses for wide vistas. The Panasonic’s lower resolution and poor dynamic range deliver less detail and more noise in shadow areas.

Wildlife and Sports

The Olympus’s fast burst rate and tracking AF shine on fast subjects. Panasonic’s sluggish autofocus and 2 fps burst place it out of contention.

Street Photography

Panasonic’s pocket size and inconspicuous design make it a stealthy street shooter where blending in matters. Olympus is bulkier but more versatile. If subtlety is king, Panasonic wins there but compromises image quality.

Macro Photography

The Olympus can leverage a huge array of dedicated macro lenses and precise manual focusing aided by its EVF and tilting screen. Panasonic’s 5cm macro focus is good for casual close-ups but lacks versatility.

Low-Light and Night Photography

Olympus’s 5-axis stabilization and better high-ISO performance enable handheld low-light shooting and astrophotography. Panasonic’s limited ISO ceiling and noise make it unsuitable beyond well-lit scenes.

Video Recording

Clear 4K-capable Olympus marginally wins. Panasonic’s 720p output is outdated but can suffice for casual home video.

Travel Photography

Olympus balances size with flexibility, while Panasonic’s tiny footprint is excellent for minimalist travel but at the expense of image quality and control.

Professional Use

The Olympus with RAW support, lens options, and advanced controls suits certain pro workflows, especially as a lightweight secondary. The Panasonic S3 is no pro tool.
