    Hi,
    My camera is an E-PL1. I have three native lenses (14-42 kit lens, 45 f/1.8, and 14 f/2.5) and a bunch of non-native glass purchased on ebay. I almost always shoot in manual mode. On occasion I wanted to use flash but being a relative noob had no idea how to adjust exposure for flash. So with a native lens, I would switch from manual to either aperture priority or auto.

    Are there any rules of thumb for changing exposure when shooting manual? Thanks in advance!

    What flash will you be using?

    First check your settings:

    In Menu/Cogs/F (Flash symbol Custom)

    Make sure you have FEC+EC set to OFF.

    If it's ON it will tie the flash EC to the camera's EC.
    When it's OFF you can set the FEC independent to the camera's EC.

    So when you pop up the flash, bring up the SCP and you'll have access to the separate flash exposure compensation mode.

    I assume we are referring to using the built in flash.

    The BIF uses TTL or manual to set its exposure and has nothing to do with the camera exposure mode. There is no reason why the cameras mode is M and the flash is Auto or Fill, TTL. In any event, using whatever mode you desire (PSAM), if the flash is is in Auto or Fill mode, the flash output is adjusted by changing the flash compensation. If you want to manually set the flash output, set the flash to Full or one of the fractional power settings.

    The built-in flash on the E-PL1.

    I know this is an older thread, hopefully it will still help

    I read somewhere that the flash on the e-pl1 has a GN of 26 (guide number.) That means that if you divide the GN by the distance to your subject you will get the f-stop you need. Shutter speed makes no difference as long as it syncs.

    So from 6 feet you need to set the aperture to approx f4. (GN/d = f)

    Do a web search for "flash Guide number" for all the gory details.

    actually it's pretty easy, you can learn the parameter from the auto mode with the native lens.
