Choosing your next camera is a significant step in your photography journey. Whether you're an enthusiast eyeing professional results or a working pro seeking reliable gear, understanding how cameras perform both technically and in the field is crucial. Today, we’ll explore two Olympus cameras separated by a decade: the Olympus E-3, a 2008 advanced DSLR, and the Olympus PEN E-PL9, a 2018 entry-level mirrorless model. Both share the Micro Four Thirds lineage yet reflect vastly different eras of camera technology.

Drawing on extensive hands-on testing, we compare their sensor technology, autofocus capabilities, build, ergonomics, and more - and crucially, how each performs across various photography disciplines. Our goal is to help you find the right fit for your creative needs, budget, and style.

First Impressions: Size, Design & Handling

One of the most visible differences is the physical size and overall design philosophy.

• Olympus E-3 is a mid-sized DSLR with a robust, weather-sealed magnesium alloy body, designed for durability and professional reliability.
• Olympus PEN E-PL9 embraces a compact rangefinder-style mirrorless design, prioritizing portability and user-friendly handling.

At 142 x 116 x 75 mm and weighing 890 g, the E-3 feels substantial in hand, offering confident grip and balance - ideal for extensive shoots in challenging environments. Its weather sealing means you can shoot in rain or dust without worry.

The PEN E-PL9, measuring 117 x 68 x 39 mm and weighing just 380 g, excels at discretion and travel convenience. Its lighter weight and smaller footprint make it ideal for street and travel photographers looking to stay nimble.

Ergonomics & Control Layout

Ergonomics deeply affect your shooting experience:

• The E-3 features a traditional DSLR layout with a full pentaprism optical viewfinder (OVF), dedicated exposure dials, and multiple control buttons for quick access.
• The E-PL9 uses a minimalist top-plate with limited physical controls but a tilting touchscreen for intuitive input.

The E-3’s control scheme suits photographers who appreciate direct, tactile control - especially when shooting action or landscapes where quick settings changes matter.

Meanwhile, the E-PL9 benefits vloggers and casual photographers with touchscreen focus points, swipe navigation and simplified button placement. However, this can feel limiting for advanced users craving fast manual overrides.

Sensor & Image Quality: Foundation of Every Photo

Both cameras use Four Thirds sensors measuring 17.3x13 mm, with a 2.1x crop factor, but advances over ten years make a critical difference.

The E-PL9’s higher 16MP resolution provides more detail - a boon for large prints or cropping flexibility. Its newer TruePic VIII processor improves noise handling and dynamic range compared to the older TruePic III in the E-3.

DxOmark scores (though the E-3 was tested on legacy platforms) hint at this leap:

• E-3 overall: 56 points, color depth 21.6, dynamic range 10.5 EV, low light ISO 571 equivalent.
• E-PL9: DxOmarks not officially published, but empirical testing confirms superior noise control and sharper output.

Practically, this means the E-PL9 excels in low-light and bright-highlight scenes, giving you cleaner shadows and richer colors.

Autofocus Systems: Precision and Speed

Fast, accurate autofocus (AF) is essential across many genres.

The E-3’s phase-detection AF excels in optical viewfinder shooting with quick lock-on, especially useful for wildlife and sports, delivering reliable focus on moving subjects.

The E-PL9’s contrast-detection AF offers more focus points and sophisticated face and eye-detection capabilities, but it relies on live view and electronic display. While contrast AF typically operates slower than phase-detection, E-PL9’s advanced algorithms help close the gap for everyday use.

For tracking fast action, the E-3's classic PDAF may feel more responsive. Yet for portraits and street shooting, the E-PL9’s eye detection provides a decisive advantage in capturing sharp eyes without manual adjustments.

Viewfinder and LCD: Seeing Your Shot

Viewfinders influence composition style and shooting posture.

• The E-3 has a bright optical pentaprism viewfinder covering 100% of the frame with 0.58x magnification.
• The E-PL9 lacks a built-in viewfinder but supports an optional electronic viewfinder (EVF).

For LCD screens:

The E-PL9’s high-resolution touchscreen vastly improves live view framing, menu navigation, and focus control (tap-to-focus, swipe). The articulated E-3 screen predated touch but still folds out nicely for awkward angles.

OVF fans may prefer the E-3’s traditional viewfinder, lending a natural, lag-free shooting experience, especially outdoors. The absence of a built-in EVF on the E-PL9 may be a drawback if you often shoot in bright sunlight where the rear LCD is challenging to see.

Burst Speed and Continuous Shooting

Continuous shooting capability can be a dealbreaker for wildlife and sports photographers.

The PEN E-PL9’s 8.6 fps burst rate with live autofocus tracking offers an advantage for capturing fleeting moments in street or casual sports photography.

The E-3’s 5 fps is slower but still capable for many action scenarios. Its buffer is limited by older storage standards.

Lens Ecosystem: Mount and Compatibility

Both cameras use the Micro Four Thirds lens mount, ensuring broad lens compatibility.

• E-3 launched early in the Four Thirds system era but here mistakenly listed with Micro Four Thirds mount - historically, it uses the Four Thirds DSLR mount, which is not compatible natively with Micro Four Thirds lenses without an adapter.
• E-PL9 employs the Micro Four Thirds mirrorless mount, compatible with an extensive, modern selection of over 100 lenses from Olympus and Panasonic, plus third-party manufacturers.

Despite this discrepancy, from a practical standpoint, the E-PL9 offers greater native access to contemporary stabilized zooms, primes, and specialty optics - critical for diverse photographic styles.

You’d want to check adapter availability if you intend to use legacy Four Thirds lenses on the E-PL9.

Build Quality & Environmental Resistance

The Olympus E-3 touts professional-grade weather sealing (dustproof, splashproof) and a magnesium alloy chassis. This makes it ideal for demanding outdoor shooting, including landscapes and wildlife in tough conditions.

The E-PL9 has a plastic body with no weatherproof sealing, prioritizing portability and sleekness over ruggedness. It’s better suited for everyday urban, travel, and casual shooting under controlled conditions.

Battery Life and Storage

The E-3 uses older CF/xD cards, which may be costlier and slower than modern SD cards used by the E-PL9.

Battery life info for the E-3 is rare, but DSLRs typically outlast mirrorless cams due to lack of continuous sensor powering. However, the E-PL9’s battery permits a decent 350 shots, still acceptable for casual shooting days.
