Its fundamental layout remains unchanged. The top dial includes typicalas well as a dedicated movie mode and Art Filters. Olympus' Live Guide, which appears in automatic, provides a user-friendly adjustment interface and shooting tips; it now works with video. I really like that you don't have to be in movie mode to record. The company has expanded its Art Filters to accommodate more variations on each filter. There's also a new Art Frame that you can add in-camera as well as overlay two filters. Real-time Art Filter preview processing can be burdensome for the camera--display refresh slows down to a crawl--so Olympus added a second display mode for Art Filters that provides a lower-quality preview. That ratchets up their usefulness quite a bit.
For shooting, Olympus changed the large buttons and four-way-navigation keys to smaller buttons and a dial for navigation. It looks a lot nicer and I like the dial, but the buttons may be small for some people. The movie record button is also recessed a bit more, to prevent accidental operation.
This newer generation model also supports the more recent version of the accessory connector for an add-on EVF, the new PEN Pal Bluetooth module, and the antenna-like macro light. There's also a ton of advanced features in the camera, but you have to read the manual, and you must turn on the double-secret menu system to know some of them exist. For instance, it's now more flexible for HDR shooting, with up to a seven-frame bracket. Every button on the camera can be redefined. You can hardwire in an exposure shift for each metering mode independently, specify how long many of the adjustment control displays persist, and add copyright information. There are also four slots for saving custom settings, but accessing them seems to be a fairly clunky process as far as I can tell; you can map one to the Fn button, but to use any other but the mapped default you have to go into the menu system. The one feature that would be nice to have is time lapse. (For a full account of the E-PL2's features and operation, download the PDF manual.)
A notable update over the E-PL1, the Olympus PEN E-PL2 delivers better photo quality and performance, as well as a nice shooting experience. But while I'd definitely recommend it to people who want to upgrade from a point-and-shoot to get better overall (and especially low-light) photo quality, it remains a little too sluggish to recommend for shooting active kids and pets.
