• Olympus E-P3 PEN (EP3) - $899 with 3x zoom
  • 12mp, built-in flash, touch screen fixed OLED display, 10 ART filters, built-in IS
  • consider getting the body only and buying the Panasonic 3x power zoom if you are willing to pay a premium for a really compact lens.
• Olympus E-PL3 PEN (EPL3) - $649 with 3x lens
  • a great option for those on a budget who don't need a touch screen and like the tilt screen
• Olympus E-PM1 PEN MINI (EPM1) - $499 with 3x lens
  • similar to the E-P3 but thinner and screen is fixed not tiltable and there are less physical controls meaning more use of the menu is needed.
• Panasonic GF-3
  • no real avantages over the E-PM1 other than the built-in flash and doesn't have the built-in IS and cannot add an EVF so go for the E-PM1 instead

• Olympus E-PL2
• Olympus E-P2
• Olympus E-PL1
• Olympus E-P1 - no remote TTL flash
• Panasonic GF1 - no IS, no remote TTL flash
• Panasonic G2 - no IS, no remote TTL flash
• Panasonic G10 - no IS, no remote TTL flash
• Panasonic G1 - no IS, no remote TTL flash

• much higher image quality than point and shoot cameras as their sensors are some 6x larger
• smaller sensors than dSLRs and thus have marginally more noise at high ISO and marginally less dynamic range capability, but the trade off is much smaller lenses and cameras.
• can use almost any lens ever made via adapters in manual focus mode
• do not have optical viewfinders but electronic viewfinders
• are not weather-proofed (except for the Olympus OM-D EM-5 and the Panasonic GH-3)
• have much easier live view and hence manual focus on legacy lenses than dSLRs as there is no need to move a mirror out of the way
• are quieter and smaller than dSLRs
• the latest generation have AF as fast as or faster than dSLRs for static subjects
• are not well suited to hand-holding with large, heavy lenses such as a 70-200mm f/2.8 but Panasonic is making compact 12-35mm and 35-100mm f/2.8 lenses which should be very nice albeit expensive.
• are best used with wide aperture prime lenses (eg. 12mm f/2.0, 20mm f/1.7, 25mm f/1.4, 45mm f/1.8, 75mm f/1.8 and 85mm f/1.4)
• are still not as good as a dSLR for AF tracking of fast moving subjects such as birds in flight.
• they lack pro and some other features such as intervalometer, fast flash sync (only 1/160th - 1/180th sec), GPS, auto-HDR, TTL compatibility with Pocket Wizard Flex TT5 radio flash system, etc
• all use SD-type memory cards
• all can shoot HD video although GH-2 and GH-3 do it at higher quality

• Olympus cameras and the Panasonic GX7 have a built-in image stabiliser which can reduce camera shake with ANY lens – you need to set focal length for legacy lenses
• other Panasonic cameras only have IS if the lens has optical IS – and this means only Panasonic OIS lenses
• brand-specific add-on EVFs:
  • Olympus VF-4 offers the BEST EVF available on any camera in 2013
    • 2.36M dots, 21mm eye relief point, lock, diopter adjustments but the eye sensor only works with E-M5, E-P5 and later Olympus cameras
  • Olympus VF-2 gives better viewing than the newer VF-3 but tends to fall off as there is no lock as with the VF-3
• Olympus has far better flash capabilities although the latest Panasonic models are finally catching up – good manual output control, remote TTL flash, TTL flash with legacy lenses, and 1/250th or 1/320th x-sync with the new cameras and flashes
  • none of the Panasonic cameras support remote TTL flash (except the GH-3, GH-4 and presumably the GX7) while the Olympus cameras do (you need the Olympus flashes ending in R for this to work, or Panasonic flashes ending in L, or the latest Metz flashes)
  • I presume the Panasonic cameras are like my GH-1 and give incorrect exposures in TTL flash mode with legacy lenses – if you use legacy lenses a lot, consider the Olympus cameras as not only you get IS but TTL flash and remote TTL flash.
  • the Panasonic GH-3 is the 1st Panasonic to support remote TTL wireless flash
• Different post-processing “ART” filters or “Film Modes”
• only the GH-1 and GH-2 have an over-sized sensor for native, uncropped 16:9 images
• the Olympus OM-D E-M5 camera and later Olympus cameras have:
  • sensor based IS working in video mode
  • Timed BULB and Live BULB
  • 5-axis, 5 EV stop IS
  • iDetect AF to preferentially AF on a person’s closest eye
• if you want the best HD video quality then the Panasonic GH-4 is the way to go.
• videos on the Panasonic cameras have less jello artefact than the current Olympus cameras and are generally higher quality
• If you primarily want to use small manual focus legacy lenses, then the Olympus cameras may be the better option as you get IS, TTL flash, and remote TTL flash and the E-P5 is better balanced with legacy lenses than is the GF-6, but you do miss out on Panasonic’s picture-in-picture manual focus functionality.
• The smallest are the Panasonic GF-6 and the Olympus E-PM2 which may suit some who just want much better image quality than a point and shoot, but still a small camera, but these lack important features such as a hotshoe, ability to use an EVF, various controls and menu items (eg. no flash exposure compensation on the GF-3), the lack of which may be very annoying for those who want to get a bit more serious or use flash.
• Unlike Olympus E-series dSLRs, none of the current Pens have IR remote control capability, but all except E-PL1 can use the RM-UC1 wired remote cable. The situation appears to be the same for the Panasonic cameras but of course, they have a different wired connector. You can buy 3rd party wired units which allow timer, intervalometer functions as well as radio wireless remote function.

• in Jan 2013, JK Imaging which had purchased the licence for the Kodak trademark, announced it will market a Micro Four Thirds camera, the Kodak S1, which will have a Sony sensor and include WiFi connectivity to smartphones.
