Summary: The Olympus PEN E-PM1 is a very compact and light SLD. It is part of a group of Micro Four-Thirds cameras launched together in July 2011. The other two are the E-PL3 Olympus PEN E-PL3 and E-P3 Olympus PEN E-P3 which feature a single control-dial and dual control-dials, respectively.
Pros: Low image noise, Conservative metering, Fast contrast-detect AF, Short shutter-lag, Almost instant video recording, Generally quick and responsive, Effective built-in stabilization, Excellent automatic Manual Focus Assist, High level of customization, Excellent build quality
Cons: Poor color accuracy, Below average AWB, Useless ISO 12800, Low contrast LCD, Poor video framing preview accuracy, Histogram disappears during EC, Not always Exposure-Priority, Uncomfortable strap eyelets, Low battery life
Conclusion: The Olympus E-PM1 may be the smallest member of the Micro Four Thirds PEN family, but it delivers the same solid build quality and good-looking images as its larger siblings—and it’s lightning fast.
Pros: Fast autofocus system. Extremely compact. Accessory port for optional EVF. In-camera art filters.
Cons: High noise at ISO 1600 and above. No built-in flash. Fixed rear LCD.
Excerpt: Father Olympus has sired a couple of siblings for the popular (and newly updated) Olympus Pen by introducing the Lite and Mini. Both tout a 12.3 megapixel sensor, interchangeable lens capabilities, 200-12,800 ISO and 1080i HD video along with a hand full of electronic filters making them perfect...
Summary: One of the best compliments I can give the Olympus PEN Mini camera is this: The Mini's look, feel, and performance level make me expect to see a much higher price tag on this model. The PEN Mini, also called the E-PM1, shoots high-quality photos, and it has a fast response level.
Summary: The Olympus E-PM1 is the baby of the 2011 PEN triplets. Nick-named the PEN Mini, the E-PM1 doesn't replace an existing model, but is a new entry in the range designed to appeal to those who want to step up from a point-and-shoot.
Pros: Built-in stabilisation works with any lens., 1080i60 movie mode with PASM., Standard hotshoe with an accessory port., Fast start-up and quick AF response.
Cons: Lacks a touch or tilting screen., Movie stabilisation artifacts., Incorrect control labels when customised., Single-use accessory port.
Summary: The Olympus PEN E-PM1 offers good image quality and manual control in a small, compact body. The E-PM1 offers nearly the same level of customization as its siblings, which should appeal to enthusiast shooters, but for compact upgraders it is easy to use in its out-of-the-box configuration.
Pros: Good low ISO image quality and resolution, Fast and responsive operation, Fast, accurate autofocus, Full HD AVCHD video, AF assist lamp, Comprehensive in-camera raw editing capability, High degree of camera and menu customization, Art filters offer fun, creative effects
Cons: High ISO noise performance lagging behind competitors' newer sensors, Overly aggressive default noise filter setting for JPEG output, Digital IS for video capture can introduce unnatural-looking footage, Lack of a hand grip can make handling awkward with heavy lenses, 16x9 format LCD is less than...
Conclusion: Starting with the cons, the same petty gripe as the E-PL3 was expected… there’s still no HDMI cable to easily plug and play FullHD and 3D capabilities directly to a HD screen. And second the non-easy option to access the ISO function...
Summary: Along with two new stable mates (E-P3, E-PL3) the Olympus PEN E-PM1 (PM1) is the latest addition to the Olympus mirrorless fleet, targeting “first-time interchangeable lens digital camera users.
Pros: Good still image quality, Very good HD video, Competitive price
Cons: Slow start up, Slick, difficult to grip finish, Only average at high ISO
Conclusion: Olympus has done a fine job moving the bar in the mirrorless interchangeable lens camera category. We liked the first one we tested (E-PL1) shooting down in New Orleans and the E-PM1 performed well in very different locales–for the most part.
