50D on camera flash not firing for fill flash outdoors

[alex_dannenbaum]

<p>I don't use my on camera flash very often. Today I wanted to use it while outddoors for fill flash. I was in a fairly shady area, shooting a portrait about 15 feet away. For some reason, it ddn't fire. I tried everything. I changed the settings, (I ran through them all), I tried the flash button, etc. After a minute or so of frustration, I was able to get the flash to pop up, however, after running through the settings again, I still could not get it to fire. <br>

When I got home tonight, and tested it indoors, tada! it seemed to work fine. This looks suspiciously like a user error problem. What am I doing wrong?</p>

<p>I have the 20D and depending on the settings you were using on it can cause the camera to decide that it doesn't need it. Also, you might not have had the correct shutter speed for the flash to sync with the shutter. I think the max is 1/250 for the 50D? </p>

<p>My best guess is that your shutter speed was probably too fast.</p>
