Olympus PEN E-PL1 Review: Retro Mirrorless Camera with Interchangeable Lenses

Olympus's PEN series began in 1959 with a film camera. In 2010, it carried the PEN name over to mirrorless digital cameras. The Olympus PEN E-PL1 is the digital interpretation of this deep-rooted design heritage — and still a strong option for those looking for a retro camera with interchangeable lenses.

What is the Olympus PEN E-PL1?

The Olympus PEN E-PL1 is an entry-level mirrorless digital camera released in 2010, featuring a Micro Four Thirds (MFT) sensor system. With its 12.3-megapixel Live MOS sensor and interchangeable lens system, it was designed to bridge the gap between compact cameras and DSLRs.

Today, the E-PL1 has evolved into a compact collector's item that keeps Olympus's legacy alive. Moreover, the MFT lens ecosystem is still active — with thousands of lens options, it's still possible to take modern shots.

Micro Four Thirds: Why Is It Still Valuable?

MFT is a lens standard jointly developed by Olympus and Panasonic. Hundreds of MFT lenses, still produced today, work on the E-PL1: Olympus M.Zuiko, Panasonic Lumix G, Sigma, Voigtländer, and more. This ecosystem makes the E-PL1 not just a collector's item, but also a viable platform for modern shooting.

Entry-Level Mirrorless? Not Really.

The E-PL1 was marketed with an "entry-level" label, but the sensor and lens quality inside belie this tag. RAW format support, manual settings, and full control — a photographer can do everything with this camera. A 2010 entry-level mirrorless can still be used for engagement shoots in 2024.

Who Is It Ideal For?

• Those who want to build a retro camera system with interchangeable lenses
• Those who want to add the legacy of the Olympus PEN series to their collection
• Those who want to enter the broad MFT lens ecosystem at an affordable price
• Those looking for a compact system camera with RAW support and full control
