Olympus PEN E-PL1 vs PEN E-PM1: An Enthusiast’s Deep Dive into Two Mirrorless Entrants

When Olympus launched the Micro Four Thirds system, they opened a new gateway into compact, versatile mirrorless cameras - proof that you didn’t need a DSLR-sized behemoth to produce quality photos. Among their early offerings were the Olympus PEN E-PL1 and, about a year later, the E-PM1. Both cameras target entry-level users craving that perfect balance of portability and creative control - but how well do they perform in real-world scenarios? And how much of an upgrade is the E-PM1 over the original E-PL1?

Having spent hundreds of hours testing these two models across genres ranging from landscapes to sports, I’m here to offer a thorough, no-nonsense comparison. I’ll walk you through their specs, hands-on usability, and how they stack up in various photographic styles, finishing with recommendations on who should pick which camera.

Let’s kick off with the physicalities - the part you feel first.

Size and Handling: Compactness vs Comfort - The Ergonomics Showdown

Upon first pick-up, the Olympus E-PL1 has a definite sense of substance. Its rangefinder-style design measures approximately 115 x 72 x 42 mm and weighs in around 334 grams - light but hearty for an entry-level mirrorless body. The E-PM1, however, strips some girth, coming in at 110 x 64 x 34 mm and just 265 grams. The subtle difference means the E-PM1 slips into small bags or even large coat pockets with ease, ideal for travel or street shooters craving discretion.

That said, the E-PL1’s slightly larger body yields a more confident grip, especially with bigger lenses. During prolonged shooting sessions, I noticed my hands appreciated the extra real estate - fewer cramps, more natural reach to buttons. The E-PM1’s minimalistic design is sleek but might be a bit fiddly for users with larger hands or those used to traditional DSLR layouts.

Looking at the top design and control ergonomics confirms these impressions. The E-PL1 features a dedicated on/off switch, a mode dial with clear tactile feedback, and a more extensive array of external controls. Meanwhile, the E-PM1 opts for a pared-down control scheme - perfect for novices but potentially frustrating if you want speedy access to manual settings.

In summary, if you value a comfortable, almost DSLR-like handling experience, the E-PL1 edges ahead. The E-PM1 scores for portability, which aligns well with its “mini” moniker.

Sensor and Image Quality: Same Sensor, Different Processors - What’s the Real Impact?

Both cameras use the same 12-megapixel Four Thirds CMOS sensor with a 17.3 x 13 mm footprint, sporting an anti-aliasing filter typical of the era. The sensor grants a 2.1x crop factor - compact lenses (in physical size) but narrower angles compared to full-frame or APS-C sensors. However, Four Thirds sensors inhabit a sweet spot when it comes to balancing detail capture and noise performance for Micro Four Thirds systems.

Image quality tests on both revealed surprisingly loyal color rendition and respectable dynamic range for their class: the E-PL1 has a measured dynamic range around 10 stops and a respectable color depth of approximately 21.5 bits, slightly edging the E-PM1’s 10.3 stops and 21.0 bits. However, the E-PM1 comes with an updated TruePic VI image processor compared to the E-PL1’s TruePic V. This newer processor accounts for better noise reduction at higher ISOs and more efficient image pipeline performance.

Real-world shooting at various ISOs confirmed this - images from the E-PM1 handled ISO 1600 and above with less chroma noise, smoother tonality, and cleaner shadows. Conversely, the E-PL1 showed more aggressive noise patterns, especially beyond ISO 800.

For the pixel peepers among us who demand razor-sharp images, both offer the same 4032 x 3024 resolution, which suffices for 13x19 inch prints without issues. But if you shoot landscapes or studio portraits and plan on heavy cropping or wall prints, keep in mind the sensor limitations; the 12MP count feels modest by today’s standards.

User Interface & Rear LCD Screen: Clearer Views and Smarter Controls

The rear LCD manifests a marked difference between these cameras. The E-PL1 packs a 2.7-inch fixed screen with a modest 230k-dot resolution - adequate, but somewhat tough to rely on under bright daylight or for critical focus checks.

The E-PM1 compensates with a larger 3-inch HyperCrystal LCD boasting a 460k-dot count - nearly doubling pixel density and offering better color fidelity and viewing angles.

From my numerous shoots outdoors, the E-PM1’s screen is much easier on the eyes when framing and reviewing shots, especially for manual focus critical work like macro or portraiture. Neither camera offers touchscreen functionality - a skip that feels more acceptable for this generation but a definite drawback today.

As for menu systems, both cameras run Olympus’s classic UI, which feels a bit involved but consistent. The E-PM1’s reduced physical controls mean more menu diving if you want to change settings on the fly, which could frustrate quick shooters.

Autofocus Performance: Contrast-Detect Workhorse Gets a Little Boost

Autofocus on both cameras is based on contrast-detection with no hybrid phase-detection pixels - a hallmark of early mirrorless models. The E-PL1 uses 11 focus points and claims face detection, while the E-PM1 uplifts that count to 35 points, improving coverage and tracking flexibility.

While testing fast-moving subjects, such as bustling city street scenes or kids at play, I found the E-PM1’s broader AF grid subtly reduces missed focus instances. Its continuous AF at 6 fps burst shooting (double the E-PL1’s 3 fps) means better chances at hitting the shot in burst mode.

Both struggle in low-contrast or dim environments, requiring patience and occasional manual focus aid, but the E-PM1 shines with more efficient AF algorithms courtesy of the updated TruePic VI processor.

Unfortunately, neither offers animal eye detection - a feature now common but absent in this generation. Portrait shooters will appreciate face detection though, which both cameras handle adequately.

Variety and Suitability Across Photography Genres

Let’s pivot from specs and into the actual fun territory - how well do these cameras play in your favorite photographic playgrounds? I’ve put both to the test across important genres.

Portrait Photography

Skin tone rendition is critical for portraits, and so is the ability to separate subjects from background. The Four Thirds sensor with its 2.1x crop can make achieving creamy bokeh a bit challenging compared to larger sensors unless you invest in fast primes.

Both cameras paired with Olympus’s sharp 45mm f/1.8 lens produced pleasing skin tones - natural with a slightly warm palette favored by many portrait shooters. The E-PM1’s superior noise handling at moderate ISO gives cleaner skin textures in low-light indoor portraits.

Face detection autofocus allowed confident eye focusing, though lack of eye-detection autofocus means you need to ensure focus precision manually at times. For bokeh, the small sensor and kit lens limitations show - the Pokey backgrounds are softer with fast primes.

Landscape Photography

Dynamic range performance between these two is very close, hovering around 10 stops - a respectable number in this sensor class but not revolutionary. For landscapes, this means mid-tone detail retention is solid but recovering extreme highlights (like blown-out skies) can be challenging.

The E-PL1’s better physical grip was helpful during longer handheld landscape sessions, but the E-PM1 compensates with a slightly higher max shutter speed of 1/4000s - allowing wider aperture use in bright light without ND filters.

Neither camera boasts weather sealing - something serious landscape photographers might demand - so extreme fieldwork in wet or dusty environments is best avoided or done carefully.

Wildlife Photography

Here’s where entry-level mirrorless models show their limits. Both cameras’s contrast-detect AF systems and burst shooting speeds (3 fps for E-PL1 and 6 fps for E-PM1) struggle to keep pace with twitchy wildlife.

The E-PM1's 6 fps was more usable for birds or small mammals in action, but autofocus hunting under long telephoto lenses is common on both. Olympus’s Micro Four Thirds lens lineup includes solid telephoto zooms but pairing these bodies with heavy lenses offsets their portability advantage.

Neither camera has animal eye autofocus, a letdown for portraiture with pets or wildlife.

Sports Photography

High-speed action requires speedy AF tracking and rapid frame rates - both of which these models partially lack.

The E-PL1’s 3 fps burst falls behind, making it challenging to capture fast-moving subjects like cyclists or football players. The E-PM1 doubles this to 6 fps, which is better but still modest compared to dedicated sports shooters topping 10 fps with phase-detection AF.

Continuous autofocus performs acceptably in good light, but low-light sports will stress both models.

Street Photography

The E-PM1’s compact size and quiet operation make it an attractive street camera - easy to carry unnoticed and quick to deploy.

You can appreciate the E-PL1’s more reliable handling, but its larger size and slower burst rates make it a bit less nimble on the street.

Low-light ISO performance favors the E-PM1, allowing usable images in dim urban environments without resorting to flash.

Macro Photography

Neither camera offers dedicated macro modes or focus stacking. I tested both paired with Olympus’s 60mm f/2.8 Macro lens, and focusing precision was adequate thanks largely to manual focus aided by live view magnification.

Image stabilization helped ensure sharp handheld shots at close distances, although the sensor-shift implementation is the same for both, providing modest stabilization.

Night and Astro Photography

High ISO noise performance is crucial here. The E-PM1’s newer processor grants cleaner images at ISO 1600–3200, extending usable ISO range for astrophotography.

Limited exposure modes and absence of bulb-mode restrict long-exposure flexibility. Also, lack of electronic shutter means shutter vibration can impact star sharpness, requiring a sturdy tripod.

Overall, the E-PM1 slightly better suits night scenes but neither is ideal for demanding astrophotography.

Video Capabilities

The E-PM1 is the clear winner here. It offers Full HD 1920 x 1080 recording at smooth 60 fps, with AVCHD and Motion JPEG codecs, compared to the E-PL1’s max 1280 x 720 at 30 fps and only Motion JPEG.

Neither camera boasts microphone or headphone jacks, so audio recording is limited to in-built mics. Both lack in-body stabilization benefits during video, making gimbals or lenses with optical IS desirable for smooth footage.

Travel Photography

The portable E-PM1 is a clear favorite for travel: its smaller size, lighter weight, superior battery life (~330 shots vs 290 shots for E-PL1), and better low-light capabilities combine into a versatile everyday travel companion.

The E-PL1’s more solid grip and control layout, while appreciated indoors or in controlled settings, become less convenient on long excursions where bulk is a liability.

Build Quality, Weather Resistance & Durability

Neither camera offers weather sealing, dustproofing, or shockproof features - typical for entry-level mirrorless cameras from this period. Both bodies are mostly polycarbonate with metal mounts, which feel solid but not rugged.

If you’re tossing gear around aggressively, these won’t be your best bet.

Lens Ecosystem and Compatibility Notes

Both cameras share the Micro Four Thirds mount, ensuring compatibility with over 100 lenses - including Olympus’s exceptional primes and zooms, as well as third-party options from Panasonic, Sigma, and others.

Lens authenticity and performance remain consistent across the two bodies. The sensor crop factor remains unchanged, and focus assistance is adequate.

Connectivity, Storage, and Battery Life

Connectivity is basic; no Wi-Fi, Bluetooth, or NFC on either. Both have USB 2.0 and HDMI out for tethering and playback.

Storage-wise, the E-PM1 accepts SD, SDHC, and SDXC cards, while the E-PL1 is limited to SD/SDHC. This hints at better future-proofing with the E-PM1.

Battery life favors the E-PM1 modestly with 330 shots per charge compared to 290 for the E-PL1.

Price and Value Proposition

At their respective launch prices, the E-PM1 was significantly costlier (~$499) than the E-PL1 (~$288). Today, in the used market, prices vary heavily but generally reflect these differences.

Is the extra money justifiable? It boils down to how much you value faster burst rates, better video, improved screen, and slightly better high ISO.
