Overview

The Olympus PEN E-PM1 is a small mirrorless camera with a retro look and interchangeable lenses. Controls are kept to a minimum. There’s no viewfinder, so every shot is framed on the rear screen.

Sensor and Image Quality

The sensor is a 12.3-megapixel Live MOS in the Micro Four Thirds format, with Olympus’s TruePic VI processor. In decent light the files are sharp enough for 8 x 10 prints or for posting online, and colors come out lively. Noise shows up early as you raise the ISO. By the time you’re shooting indoors at night, the grain is obvious.

Autofocus and Speed

There are 35 contrast-detection focus points. On a still subject it’s accurate. In dim light or on anything moving, it slows down and sometimes misses. Burst shooting runs at about 3.5 fps, which covers snapshots of kids and pets on a good day and won’t keep up with sports.

Screen

The rear screen is 3 inches with 460,000 dots. It’s bright and clear, but it’s not a touchscreen, while the Lumix GF3 and Canon EOS M both have one. Coming from either, you’ll notice.

Features

Art Filters (Pop Art, Soft Focus, Grainy Film) apply their effect as you shoot, so you see the result right away. Editing software can copy most of these looks later. In-camera tools let you resize, crop and adjust color. Video is HD, fine for family clips.

Lenses

The lens mount matters more than any other spec here. Olympus and Panasonic both make lenses for Micro Four Thirds, so you can start with the kit lens and add a macro or a telephoto later. A fixed-lens compact gives you no such option.

Handling and Battery

The automatic modes suit a beginner. If you like to set everything yourself, you’ll find the manual controls limited. The BLS-5 battery is rated at about 300 shots per charge, enough for a day of casual shooting, and I’d take a spare on a trip.

How It Compares

Panasonic Lumix GF3: the same sensor format at 12.1MP, with a 3-inch touchscreen that makes menus and playback easier. Image quality is close.
Sony NEX-C3: a larger 16.2MP APS-C sensor, which should be cleaner in low light and give shallower depth of field.
Canon EOS M: 18MP APS-C with a touchscreen, in a bigger body. You gain resolution and lose size.

Verdict

The E-PM1 is for someone moving up from a phone or a basic compact who wants to swap lenses without buying a DSLR. It’s easy to use and the body is small. The screen is low-resolution and not touch-sensitive, manual controls are limited, and high-ISO files are noisy. If you shoot in dim light, shoot action, or want a lot of control, buy something else.
