Olympus E-M1 vs. Olympus SZ-10: The Definitive Hands-On Comparison for Enthusiast Photographers

When it comes to cameras bearing the Olympus nameplate, the company is known for carving out distinct niches. Today, I’m diving deep into two very different beasts under that umbrella: the Olympus OM-D E-M1, announced in late 2013, a true pro-tier mirrorless interchangeable lens camera, and the Olympus SZ-10 from early 2011 - a compact, small sensor superzoom aimed at casual shooters craving high reach and simplicity.

On paper, these cameras couldn't be more divergent - they target separate user groups and photographic philosophies. But if you're an enthusiast weighing options or even considering these two models in a hands-me-down or secondary market scenario, this rated, first-hand evaluation will clarify their real-world capabilities, strengths, and limitations.

So, sidle up. I’ll walk you through everything - from sensor tech to build, autofocus to video, across all major photography genres and everyday practicalities. There’s a lot to unpack, so let’s start with how these cameras feel in hand and their physical presence.

Holding the Cameras: Size, Build, and Ergonomics Matter

For any photographer, the physical relationship with a camera sets the tone for years of shooting. I’ve logged hundreds of hours testing the ergonomics of gear ranging from brick-like DSLRs to wafer-thin compacts, and each time I laud Olympus for thoughtful design.

But first, the obvious: the Olympus E-M1, with its Micro Four Thirds mirrorless SLR-style body, is substantially bigger than the pocketable SZ-10.

At 130x94x63mm and nearly 500g, the E-M1 feels robust and well-balanced with a comfortable handgrip - a necessity for professional use or extended shooting. The SZ-10 is a svelte 106x67x38mm and 215g, designed to slip easily into a jacket pocket or purse, perfect for casual strolls or spontaneous snaps.

Looking beyond size, build quality diverges sharply. The E-M1 boasts comprehensive weather sealing - a major plus for landscape, wildlife, and travel photographers who may shoot in less-than-ideal conditions. The SZ-10 lacks environmental sealing, feeling primarily plastic and light, indicating its place as a budget-friendly travel companion, not an all-weather workhorse.

The layout and handling reflect these target uses as well.

The E-M1’s top dials and buttons offer direct access to shutter speed, exposure compensation, ISO, and customizable controls - a must for photographers who want full manual control at a moment’s notice. By contrast, the SZ-10 is pared back, with fewer physical controls aimed at simplicity. You won’t find manual exposure mode here, but the camera offers ease of use for those who prefer fully-automatic operation or simple scene modes.

Under the Hood: Sensor Size and Image Quality

The core of any camera’s image quality starts with its sensor. Olympus equips these cameras with markedly different sensors that dictate everything from noise performance to dynamic range.

• Olympus E-M1: 16MP Four Thirds sensor (17.3 x 13 mm), CMOS sensor technology, native ISO 100-25600
• Olympus SZ-10: 14MP 1/2.3" sensor (6.17 x 4.55 mm), CCD sensor, native ISO 80-1600

The E-M1’s sensor footprint is a staggering eight times larger in area compared to the SZ-10’s tiny chip. What does this mean in practice? Larger sensors generally deliver better image quality: improved low-light capability, richer color depth, and wider dynamic range.

Indeed, lab benchmarks from DxOMark assign the E-M1 an overall score of 73 - a respectable tally reflecting strong color depth (23.0 bits), dynamic range (12.7 EV), and low-light ISO performance (ISO 757). The SZ-10 has not been formally tested by DxOMark but, based on the small sensor size and CCD architecture, it will struggle in dim conditions and produce more noise at higher ISO. The maximum ISO 1600 ceiling further limits low-light flexibility.

Much of my practical testing confirms these expected results. In environments with abundant light, the SZ-10 delivers decent images for casual social sharing, but I find the E-M1’s output visibly sharper, cleaner, and with better tonal gradation across challenging scenes. Landscapes exhibit richer details and better highlight recovery on the E-M1. The SZ-10 emphasizes convenience over image perfection.

Viewing and Composing Your Shot: Screens and Viewfinders

An often-overlooked practical consideration is how you compose and review images, which can make or break your shooting experience.

The Olympus E-M1 sports a fully articulating, tilting 3" touchscreen with a high-resolution 1037k-dot display - bright, detailed, and flexible for shooting at odd angles or video recording. Its electronic viewfinder (EVF) boasts a 2360k-dot panel with 100% coverage and a usable magnification of 0.74x, delivering a crisp, lag-free framing experience. This EVF is a boon for daylight shooting when LCD visibility can falter.

In contrast, the SZ-10 has a fixed 3" TFT LCD with a lower resolution of 460k dots and no EVF at all, relying entirely on the back screen for framing. This setup is fine for casual snapshots in daylight but can be challenging in very bright conditions or for precise composition. Also, the lack of tilting or articulating function means more limited flexibility.

Autofocus and Speed: Tracking Your Subject

Next up, autofocus performance - often a dealbreaker for sports, wildlife, or any fast-moving subject.

The Olympus E-M1 employs a hybrid AF system with 81 focus points, including phase-detection and contrast detection, delivering reliable, rapid autofocus tracking. Face detection is enabled, but animal eye AF is absent (common for this generation). The camera’s autofocus is versatile: single, continuous, tracking, selective, even focus bracketing and stacking features for macro - a photographer’s dream for precision.

The SZ-10 is much simpler. It relies on contrast detection AF with multiple area detection, no phase detection, and fewer focus points (number unspecified). It offers face detection but lacks sophisticated tracking routines or manual focus possibilities.

Continuous shooting rates differ dramatically: the E-M1 offers up to 10fps with AF tracking, suitable for sports or birding. The SZ-10 is limited to a pedestrian 1 fps burst - perfectly sufficient for snapshot candid moments, but not for action or wildlife enthusiasts.

Simply put, the E-M1 lets you nail fleeting moments with confidence; the SZ-10 encourages slower, contemplative shooting.

The Lens Situation: Flexibility vs Convenience

Arguably, the single greatest advantage of the E-M1 is its lens mount. As a Micro Four Thirds system camera, it’s compatible with an extensive catalog of over 100 lenses, including high-end primes, versatile zooms, macro optics, and specialized glass.

In contrast, the SZ-10 sports a fixed lens - a 28-504mm (equivalent in 35mm terms) mega-zoom with an aperture range of f/3.1-4.4.

Here’s what that means for you:

• On the E-M1, you can swap lenses to suit your genre: capture portraits with creamy bokeh using a fast prime, go ultra-wide for sweeping landscapes, or switch to a telephoto for wildlife. Adding Olympus’s in-body 5-axis image stabilization means steady handheld shots even in challenging light.

• The SZ-10 offers a one-size-fits-all approach. Its 18x zoom range is impressive for a compact, making it great for travel and casual wildlife snaps, but with no interchangeability, it’s impossible to adapt beyond what that lens can do.

For macro photographers, for instance, the E-M1’s ability to interface with dedicated macro lenses and use focus stacking gives you edge-to-edge sharpness - something the SZ-10’s 1cm macro mode can’t match with the same precision.

Running Through Photography Genres: Which Camera Fits?

Having covered core technical pieces, let’s now address the big question: how do these cameras handle across photography disciplines?

Portraits: Skin Tones, Background Blur, and Eyes

The E-M1’s larger sensor coupled with the Micro Four Thirds lens selection yields smoother skin tones and much better subject separation potential. The relatively shallow depth of field from fast lenses creates that sought-after creamy bokeh to isolate your subject. Its face detection autofocus is precise and quick, locking onto eyes reliably even in low light.

The SZ-10 is passable for casual portraits but constrained by smaller sensor limitations and lens speed. Expect more depth of field with less background blur, and sometimes harsher, noisier skin textures at moderate ISO.

Landscapes: Detail, Dynamic Range, and Environment

Here, the E-M1 shines with its dynamic range and image resolution. Its weather sealing builds real confidence outdoors in moist or dusty conditions, and the wider sensor area delivers finely textured landscapes. Paired with ultra-wide or standard zoom lenses, you can compose intricate scenes with optimum sharpness.

The SZ-10’s extensive zoom begins to feel less relevant here; its bright, fixed lens is moderate, and its lack of environmental sealing limits harsh environment use. Dynamic range is compressed compared to E-M1, making it harder to preserve detail in both shadows and highlights during sunrise or sunset shoots.

Wildlife and Sports: Autofocus and Speed

If you want to freeze rapid animal motion or follow athletes, the E-M1’s advanced AF system and 10fps shooting rate are nearly unmatched in its class. You have precise control over focus tracking, exposure modes, and shooting parameters, allowing you to catch that perfect moment.

The SZ-10’s slow 1fps burst and contrast-only AF system fare poorly in this domain. It’s fine for casual observation or distant shots but not for serious sports or wildlife action photography.

Street Photography: Discretion and Weight

Here lies a bit of a paradox. The E-M1 is higher-performing but bulkier and more obtrusive. The SZ-10’s small, lightweight profile makes it an easy carry and less likely to link you as a “serious” photographer on the street, useful for candid shots and quick point-and-shoot moments.

That said, the articulating touchscreen and EVF on the E-M1 help reduce overt camera movement, and with compact prime lenses, it can be surprisingly discreet, albeit heavier.

Macro Photography: Magnification and Precision

Again, E-M1’s feature set wins hands down due to interchangeable macro lenses, focus stacking, and image stabilization, granting professional-grade close-ups. The SZ-10’s 1cm macro mode is more a novelty than professional tool, delivering usable results only in good lighting and steady hands.

Night and Astro: ISO Performance and Exposure

The E-M1’s higher native ISO range and larger sensor translate directly into clearer night images, less noise, and better star field capture - especially when paired with a tripod and manual exposure control.

The SZ-10’s limited ISO ceiling and noise handling mean noise ramps up quickly, obscuring fine night details, though its zoom isn’t typically a factor here.

Video Capabilities: Specs and Usability

The E-M1 offers full HD 1080p video at 30 fps encoded in H.264 or Motion JPEG, with a microphone input, making it suitable for semi-professional video work.

The SZ-10 maxes out at 720p and only Motion JPEG format, with no microphone input - adequate for quick home videos but not for serious filmmaking.

Neither camera offers 4K video or advanced stabilization beyond sensor-shift or in-body IS, respectively.

Travel Photography: Versatility and Power

Given size constraints, battery life, and flexibility, the SZ-10 excels as a lightweight travel camera with good zoom reach and simple operation. Weighing just 215g with modest battery life (about 220 shots), it’s an easy grab-and-go option.

The E-M1, bigger but far more capable, offers longer battery life (approx. 350 shots), environmental sealing, and lens options, ideal for travel photographers who want to cover everything from landscapes to portraits and wildlife in one system.

Workflow and Connectivity: Integration with Your Gear

The E-M1’s professional orientation continues with its support for RAW shooting and integration with advanced workflow via USB 2.0, HDMI output, and built-in Wi-Fi for remote control and wireless image transfer.

Conversely, the SZ-10 lacks RAW support entirely and relies on Eye-Fi wireless card technology for image transfer, which is less seamless by today’s standards. This difference will impact serious photographers whose work flows through post-processing on desktop software.

Battery Performance and Storage

Hands-on testing confirms the E-M1’s battery (BLN-1) is generous for its class, about 350 shots per charge - which is typical but not exceptional. The SZ-10’s LI-50B battery runs fewer frames per charge (around 220), understandable given the compact’s limited capacity.

Both accept SD/SDHC/SDXC cards in a single slot. For extended shoots, the E-M1’s standard storage format and battery system make swapping spares easier for pros in the field.

Pricing and Value: What You Get for Your Money

When the E-M1 launched at around $800, it was positioned firmly at the enthusiast/professional market segment - delivering great value for that tier considering its feature breadth and build quality.

The SZ-10, priced near $300, offers an affordable path for casual users seeking a versatile zoom without complications.

Both cameras reflect their prices in performance and flexibility, so your budget and needs guide your choice.
