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.
Summary: The only mirrorless compact that falls within the price bracket of Rs.30,000 is the 14 megapixel Sony NEX-5k, which is currently retailing for Rs.24,500. The advantages it offers over the E-PM1 are tilting display and larger sensor. Given a choice between the two, the Sony NEX-5k is clearly a better bang for your buck. But if you want something really light and compact, then the Olympus E-PM1 is the only mirrorless compact in this price bracket.
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 ideal for viewing 4:3 still images, Use of clip-on flash precludes use of an EVF or any other accessory port item, No live view in continuous shooting mode, No touchscreen in...
Summary: Olympus started the mirrorless interchangeable lens digital movement and with three new entries into this market niche shows no sign of wishing to cede this territory to more recent arrivals. While the PM1 is nominally the entry-level model in this newly introduced triumvirate, a lot of the performance hardware and features of its higher-priced siblings are present in the PM1 as well.
Pros: Good still image quality, Very good HD video quality, Good AF and shutter performance, Relatively low price in the class
Cons: A bit slow to start up, Somewhat slick feeling finish, Average high ISO performance (3200+)
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. We recently used several Sony mirrorless models , even taking similar shots with the PM1 and NEX-5N. With its larger sensor, the Sony outperformed the Olympus but you’ll definitely pay a lot more for it (around $200).
Excerpt: Camera manufacturers have been slugging it out in an entirely new product category this year: the micro sharpshooter. Much as the revived Mini Cooper helped change the compact car category in the last decade by offering style and performance in a small package, Panasonic, Sony, and Olympus are hoping their compact system cameras (CSC), which use tiny interchangeable lenses, will present a pint-sized alternative to digital SLRs.
Summary: If you’re stepping up from a standard compact camera you’ll feel quite at home with the PEN mini, and love its enhanced image quality, but DSLR users may well find it somewhat frustrating to use.
Olympus' smallest interchangeable lens camera is capable of producing very clear images

Summary: The Olympus PEN E-PM1 Mini dishes out image quality that's on par with the high-end PEN E-P3, but for a more reasonable price. We were impressed with its clear and vibrant results, as well as its useful high ISO settings. However, its video quality isn't great.
Pros: Clear image quality, Good high ISO performance, WYSIWYG LCD screen
Cons: Flash not built in, Video capture is "wobbly"
Conclusion: Although theoretically all Olympus digital Pen cameras have been targeted at compact “upgraders” since the E-P1 was unveiled in late 2009, the E-PM1 is the one that offers the most obvious step-up potential for happy snappers wanting to up their game. Available in our black, white, silver, dark brown or purple, the fact that it’s the most diminutive Pen yet doesn’t, for us, unequivocally tip the balance in the Mini’s favour, as the old school Tonka-toy like bulk of the...
Pros: Good value when bought with standard zoom, competent and consistent performance, quick and responsive for the most part
Cons: No integral flash, rear operational controls and on-screen symbols are tiny, no dedicated delete button nor handgrip
