Ok, this may be completely dumb question, I've never own a dedicated flash, 540 arrived yesterday, I after reading the manual over and over again, and few test shots, very confused:
P-TTL, manual states "flash pre-fires" so more accurate reading via multisegment metering takes place" - I've read this question in this thread
https://www.pentaxforums.com/forums/pentax-camera-accessories/3256-p-ttl-pre-...n-visible.html
I'm in the fairly dark room, flash set on P-TTL, A-Zoom, leading curtain sync - I see no pre-flash, only the "red light" in the front sensor is being activated...
Camera set on Av... Am I doing something wrong? Shouldn't I see the pre-flash? Even tried holding the camera off to the side, not looking into the viewfidner...
Regards,
D
