Olympus PEN E-P1 Mirrorless MFT (Micro Four Thirds) Camera Body, Silver/Silver {12.3MP}

Olympus PEN E-P1: The Rangefinder-Style Camera That Started Micro Four Thirds

The E-P1 packs a Four Thirds sensor and TruePic V processing into a rangefinder-style body that ditches the mirror box and optical viewfinder entirely, framing everything through live view on its 3-inch HyperCrystal LCD. That shorter flange back distance is what lets the body stay compact while still mounting a full lineup of Micro Four Thirds glass, plus existing Four Thirds lenses via an adapter.

Sensor-shift image stabilization works with whatever lens you attach, useful for handheld shooting at slower shutter speeds without hunting for a stabilized lens. The shutter runs from 60 seconds up to 1/4000 sec, giving street and travel shooters room to work in bright midday light or stretch exposures after dark. Full manual, aperture priority, and shutter priority modes are on board, along with 3 fps burst shooting for casual action work. A hot-shoe accepts external flash units, with flash modes covering fill-in, slow sync, and manual output across three levels.

RAW capture is standard, and the camera shoots 720p video in Motion JPEG with stereo audio, a genuine crossover feature for the era. Exposure compensation runs to plus or minus 3 stops, and AE bracketing gives you three frames per sequence for tricky lighting. At 355 g, it's a body built for carrying all day, not just for weekend outings.

Who It's For

Street and travel photographers benefit from the compact rangefinder-style body and fixed 3-inch LCD, which make framing discreet and the whole kit light enough for a full day out at 355 g. Enthusiasts moving up from compacts get sensor-shift stabilization that steadies handheld shots regardless of the lens mounted, plus aperture priority and shutter priority modes for deliberate exposure control. Those experimenting with hybrid stills-and-video work can lean on 720p Motion JPEG recording with stereo sound, a rare combination when this body launched. Adapted-lens shooters, meanwhile, can run existing Four Thirds glass through an adapter alongside native Micro Four Thirds lenses, extending the system without starting a lens collection from scratch.

FAQ

What mount does the E-P1 use, and can I adapt older Four Thirds lenses?

The E-P1 uses Micro Four Thirds, which has a shorter flange back distance than the original Four Thirds mount. Existing Four Thirds lenses work via an optional adapter, though you'll keep the native 2× focal length multiplier either way.

Does the E-P1 have an optical viewfinder?

No. It frames everything through the 3-inch HyperCrystal LCD on the back in live view mode, which updates in real time as you adjust exposure or white balance.

What shutter speed range does it offer?

60 seconds to 1/4000 sec, which gives you flexibility for both bright daylight and long exposures without needing ND filters on every lens.

How does the image stabilization work?

It's sensor-shift stabilization, so it works with any lens you mount-no need to hunt for optically stabilized glass. Useful for handheld shooting at slower shutter speeds.

What video capabilities does the E-P1 have?

It shoots 1,280 x 720 at 30 fps in Motion JPEG format with stereo audio. Straightforward codec, no fancy frame rates, but genuine video capture for the era.

How long does the battery last on a single charge?

The BLS-1 lithium-ion battery is rated for 300 exposures per charge under CIPA testing conditions. Real-world life varies based on how much you rely on live view versus chimping.

Can I shoot RAW files?

Yes, RAW is standard. The camera also captures JPEG at multiple aspect ratios (1:1, 4:3, 3:2, 16:9) and resolution options down to 640 x 480.
