As I use M mode is most of time, is there any external flash tha tworks with the exposure indicator? I'm lost about flashes.
Thanks
Av mode sucks as it is almost impossible to get the camera to change shutter to max sync speed of 1/180 by changing exposure. Tv should be fine, but really with flash I like to control DOF, so not that great. Experimenting for a few minutes with P mode, I found I could control shutter speed better and it calculates exposure with flash into account.
I am new to flashes as well, so please double check of everything I say...AFAIK, there is no flash with expousure indicator like you describe. P-TTL is suppose to work to compensate EVERYTHING for you and thus an indicator is not needed, and if you argue that P-TTL is not very accurate the same would be true of any technology that can run an exposure indicator. So, there is no need for it. There are lot's of articles on 'strobist' to how to quickly get at the correct flash exposure by trial and error and they say in time you would know instinctively (they recommend M mode for the camera and Manual for flash, so no P-TTL). I am waiting for my 540 to experiment and I am hoping I can balance light in P-TTL/
