==============
Note about Olympus service. It turns out that my camera had an issue with taking picture at fast shutter speed (1/4000s). I called the service and sent it in. It was fixed by week's end, and was shipped it out by 2nd Day Air. It was all for free as my camera is still under warranty. I did not get a refurbished unit; I got mine back. When I tested my 'fixed' camera, I found everything was working as expected and no more problems at high shutter speed. Big kudos for Olympus service!

One key feature I forgot to mention is the in-body image stablization (IBIS). Olympus has the IBIS whereas Panasonic only supports the IS built into the lens. There are PROs and CONs of IBIS. However this comes in handy in many cases, and I prefer camera having IBIS where some lenses do not come with IS built-in (OIS). Some of my lenses do not have OIS, and if I do not use IBIS on Olympus, images would not be as... Read more

I've owned this camera for a few weeks now, so I just wanted write a few notes about this camera that get neglected.

1. The image stabilization is only good up to 4 fps, but the default multi shot modes are 5 fps or 3 fps. To get 4 fps, you have to use a custom menu setting.

2. Always shoot in multi shot mode. Single shot mode will cause camera lag (my guess is that it waits for the SD card to finish writing in single shot mode). This lowers your shot to shot times down to about 1.5 fps as the camera will just ignore your shutter press. Shooting in multi shot mode solves this problem, at the expense of not always seeing your next shot.

3. Buy the Panasonic 20mm f1.7 lens if you want to take any indoor shots without a flash. The kit lens, at f3.5, is just not fast enough indoors. Your shots will come out at 1600 ISO and contain blur or noise, depending upon your noise filtering setting, usually both, because f3.5, just doesn't cut it. Okay, that might... Read more

I've been using E-PM1 for a couple of weeks. It's very nicely build and appears to be metal front, back or sides and the top (E-PL2 has only metal front panel). The menu is cleverly designed so you won't miss the additional external controls all that much. Rec button and "right" & "down" buttons can be customized. E.g., you can set Rec button to serve as AEL/AFL, AF/MF switch, "Magnify", "Tele-converter", etc. In addition, if you turn off "keep WB warm" in the menu (it's on by default), the colors will be much better especially indoors. Don't forget to dial flash exposure compesation "+1EV" (the camera will remember this setting) for proper exposure because the bundled flash is always in semi-bounce position when activated.
Overall, great little camera with super fast AF (incl. continous AF in HD video), fast buffer clearing with a huge number of customizations available. 5.5fps burst mode and art filter bracketing is really cool. So far my basic settings: Noise filter off, "keep... Read more
