Olympus PEN E-PM1 vs Olympus SZ-11: A Hands-On Comparison With Real-World Insights

When it comes to Olympus cameras released around 2011, you might stumble across two very different approaches to photography: The Olympus PEN E-PM1, a compact, entry-level Micro Four Thirds mirrorless camera, versus the Olympus SZ-11, a highly portable superzoom compact. Both appeal to budget-conscious photographers, but they occupy distinctly separate niches. Having spent hours testing these two under various conditions, I’m here to share an honest, in-depth comparison so you can decide which fits your photography style and wallet best.

Let’s dissect their capabilities, quirks, and value proposition from the standpoint of a seasoned enthusiast (with a healthy dose of cheapskate wisdom thrown in for good measure).

First Impressions and Build: Handling, Size, and Ergonomics

Picking up a camera, it’s immediately clear how different these two are in form and feel.

The Olympus E-PM1 is a rangefinder-style mirrorless camera designed with a minimalist but functional approach. It weighs in at about 265g and measures 110 x 64 x 34 mm. Its body shows some purposeful design decisions - a fixed 3-inch HyperCrystal LCD with anti-reflective coating to aid in various lighting, and a decent array of control dials for aperture and shutter priority.

Conversely, the Olympus SZ-11 is a modestly chunky compact zoom, lighter at 226g but with a thickness of 40mm due to its massive 20x zoom lens (25-500mm equivalent). It’s designed for pocket-friendly reach and convenience - no interchangeable lenses here. Controls are pared back with no manual exposure modes or aperture priority.

In side-by-side handling, the E-PM1’s club-worthy thumb grip provides a better hold and feels more robust in your hands versus the thin, rounded SZ-11, which is a bit of a slippery soap bar especially in cold or wet conditions. For those quick shutter moments or extended shoots, I’d pick the E-PM1’s ergonomics any day. However, if weight and zoom range are priorities - perhaps for travel or casual snapshots - the SZ-11 wins.

The top view further reveals these differences:

The E-PM1’s dedicated dials and buttons make it a breeze to tweak settings on the fly - a serious plus for enthusiasts and budding pros. The SZ-11’s simplified control scheme is more consumer-focused, limiting direct access to things like ISO or exposure compensation.

Build-wise, neither camera boasts weather sealing or ruggedness, so treating them as delicate tools is advisable. The E-PM1’s Micro Four Thirds mount gives it more future-proofing via lens upgrades. The SZ-11’s fixed lens means you’re pretty much married to its optics.

Sensor Technology and Image Quality: Size, Resolution, and Performance

Let’s get to the heart of image quality - the sensor.

The Olympus E-PM1 employs a Four Thirds CMOS sensor measuring 17.3 x 13 mm, roughly 225 mm² of imaging area. It offers 12 megapixels (4032x3024 resolution) with a native ISO range of 100 to 12,800, and an anti-alias filter to reduce moiré. The sensor is paired with Olympus’s TruePic VI image processor, which helps improve noise reduction and color accuracy.

On the flip side, the SZ-11 uses a significantly smaller 1/2.3-inch CCD sensor (6.17 x 4.55 mm, ~28 mm²), but cranks up the resolution to 14 megapixels (4288x3216). Its ISO tops out at 1600 natively, with no option for RAW shooting - all images are JPEG compressed. The SZ-11 uses the older TruePic III+ processor tailored towards compact cameras.

In practical testing, you’ll notice the E-PM1’s larger sensor delivers noticeably cleaner images with better dynamic range and richer color depth, especially in low light or high contrast scenes. The Four Thirds sensor size advantage is crucial - it provides bigger photosites, making for less noise and more detail retention. In a landscape shoot at dawn, for example, the E-PM1’s 10.3 EV dynamic range lets you pull shadows without blowing highlights, something the SZ-11 struggles with given its smaller sensor and limited ISO.

Detail sharpness also defers to the E-PM1, despite the SZ-11’s higher megapixel count - a classic case of sensor size advantage outweighing resolution numbers. The Olympus penalty for a small sensor here manifests as increased chromatic aberration and less pleasing bokeh at telephoto due to the tiny sensor constraints.

Autofocus and Shooting Speed: How Fast and Accurate Are They?

Autofocus performance is often make-or-break for shooting unpredictable subjects - let’s talk speed and accuracy.

The E-PM1 features a contrast-detection AF system with 35 focus points and face detection. It supports continuous autofocus and tracking modes, which proved decent in daylight and reasonable indoor lighting. Its autofocus locks fairly quickly given the budget tier, though slow in very dim environments as expected for a contrast detection system without phase detection pixels.

The SZ-11, meanwhile, has a basic contrast detection AF as well but with unknown focus points and no continuous autofocus - AF locks only once per shot in single mode. It too supports face detection but lacks any manual focus hardware.

Burst rates tip slightly in favor of the SZ-11, clocking 7fps at full resolution versus 6fps for the E-PM1, but continuous autofocus during burst is only possible on the E-PM1.

In wildlife or sports scenarios, neither camera is especially fast or reliable compared to modern beasts, but if you want subject tracking during fast action, the mirrorless E-PM1 is the better choice due to flexible AF modes, even if it’s no Nikon D500. For casual use, the SZ-11’s simple AF is acceptable.

Viewing and User Interface: Screens, Viewfinders, and Handling Controls

Both cameras employ fixed 3-inch LCD screens with 460k dot resolution - neither touchscreen-enabled nor articulating.

The E-PM1’s "HyperCrystal LCD" boasts an anti-reflective coating, boosting visibility outdoors, while the SZ-11’s TFT panel is more prone to glare. The E-PM1 also offers an optional electronic viewfinder attachment (sold separately), allowing for more traditional composition - a feature absent on the SZ-11.

Menu systems reflect their target users: The E-PM1’s interface is fairly robust with customization options and numerous exposure modes. The SZ-11 keeps things simple - it’s quick to navigate by design but offers no manual controls or customization.

The absence of an EVF in both limits shooting flexibility, but the E-PM1’s viewfinder add-on potential gives it a leg up in professional or outdoor use, where LCD glare can impede composition.

Lens Ecosystem and Versatility: Interchangeability vs Superzoom Convenience

Here is where the cameras define their identities.

The Olympus E-PM1’s Micro Four Thirds mount invites you into one of the richest mirrorless lens ecosystems. From fast primes for portraits to ultra-wide landscapes and telephoto for wildlife, the lens options (over 100 lenses) give you creative freedom.

The SZ-11 is a fixed superzoom with a 25-500mm (20x) equivalent lens, aperture F3.0-6.9, perfect for those who want optical reach without lugging around lenses or worrying about changing glass. It even offers macro focusing down to 1 cm, impressive for close-ups.

For enthusiasts who value image quality, focusing control, and future upgrades, the E-PM1’s interchangeable lens system wins easily. But for casual travelers or point-and-shoot fans craving a Swiss Army zoom, the SZ-11 cannot be beaten on convenience and pocketability.

Specialized Photography Disciplines: How Do They Stack Up?

Time to break down each camera by popular photography uses - I’ve tested them across these scenarios to see how well they perform.

Portrait Photography

The E-PM1 offers superior skin tone rendition thanks to its larger sensor and better color depth (21-bit). Its ability to throw backgrounds out of focus with wide-aperture lenses opens up creative possibilities - the kit lens is okay, but a fast 45mm f/1.8 is where portraits sing. Accurate face detection AF adds confidence.

The SZ-11’s tiny sensor and slow lens aperture mean portraits look flatter, with less subject-background separation and more noise indoors. Face detection helps, but the image quality limitations reduce its appeal for serious portraiture.

Landscape Photography

Here, sensor size, resolution, and dynamic range dominate. The E-PM1’s Four Thirds sensor with 12 MP yields files that hold up well for prints up to A3, preserving detail and shadow gradations. I tested several landscape scenes and was impressed by color fidelity and detail.

The SZ-11’s high pixel count is hamstrung by its size and JPEG-only files; results tend to be softer and noisier once you push exposure adjustments. The physical size is more portable, but weather sealing is absent from both, so bring a raincoat.

Wildlife and Sports Photography

Neither camera is a professional sports sniper, but the E-PM1’s faster continuous AF and burst shooting edge make it better suited for shooting moving subjects, especially with long telephoto lenses. While the SZ-11’s 20x zoom is tempting for wildlife, the smaller sensor and autofocus limitations mean coarse images at maximum zoom and slow focus. Plus, its maximum shutter speed tops at 1/2000s, which restricts freezing fast action, whereas the E-PM1 hits 1/4000s.

Street Photography

For discreet shooting, the SZ-11 is more compact and less conspicuous for candid moments, though its clunky zoom lens extends fairly noticeably when powered on. The E-PM1’s bulk and retro looks may draw more attention, but its silent shutter mode - I checked - is absent, which may matter for some street shooters. Low light performance favors the E-PM1, helpful for dimly lit streets.

Macro Photography

The SZ-11 offers a superb macro focusing distance (1 cm), making it great for casual close-ups of flowers or insects, aided by its stabilized lens. The E-PM1 relies on lenses for macro, so you’ll need to invest in a dedicated macro prime or extension tubes. Its sensor-based image stabilization does help though.

Night and Astro Photography

This is where the E-PM1 takes a definitive lead: Higher ISO capability (up to 12,800), larger sensor, and better noise handling mean cleaner low-light images and less hot spots in starscapes. The SZ-11 maxes out at ISO 1600 and produces noisier results. Neither offers built-in intervalometer or bulb modes, so external solutions are needed for advanced astro work.

Video Capabilities

The E-PM1 shoots Full HD at 1080p/60fps, records in AVCHD and Motion JPEG formats, but lacks microphone or headphone ports - limiting professional audio work. It does have sensor-based stabilization, which is helpful.

The SZ-11 tops out at 720p HD and only 30fps, with Motion JPEG compression. Both cameras’ video quality is basic by modern standards but serviceable for casual use.

Power, Storage, and Connectivity

The E-PM1 uses a BLS-5 battery with a rated 330 shots per charge, which is good for a mirrorless of its time. The SZ-11’s LI-50B battery offers around 200 shots, which can feel restrictive on longer outings.

Both cameras support SD/SDHC/SDXC cards but only have single slots - no redundancy or speed advantage here.

Connectivity is limited: No Wi-Fi, Bluetooth, or NFC on either camera, so quick sharing or remote control is off the table - a downside for today’s social shooters. Both have USB 2.0 and HDMI ports for tethering or video output.

Price-to-Performance: Choosing Based on Your Budget

At launch, the Olympus E-PM1 retailed around $499 body-only, while the SZ-11 was about $253. This price gap accurately reflects their capabilities - the E-PM1’s superior sensor, lens flexibility, and manual control carry a premium.

If you’re a beginner or need a simple grab-and-go superzoom with a small footprint, the SZ-11 represents tremendous value. Just don’t expect DSLR or mirrorless quality - it’s a big step down in sensor tech and flexibility.

If you want to learn photography properly, experiment with lenses, shoot in RAW, and eventually do serious work, the E-PM1 offers a platform to grow. It’s also a decent stepping stone into Olympus’s more advanced PEN series.

Objective Performance Scores

For a summary, here are their DxO Mark overall and specialty ratings, with my practical observations aligning well:

• Olympus E-PM1: DxO Overall Score 52. Color Depth 21 bits. Dynamic Range 10.3 EV. Low-Light ISO: 499.
• Olympus SZ-11: Not DxO tested but sensor specs and real-world tests place it notably behind - smaller sensor, noisier images.

Breaking down genre-specific performance:

The E-PM1 dominates in portraits, landscapes, and low-light shooting, while the SZ-11 edges slightly in casual macro and superzoom reach.
