Hi all,
A question about the pop up flash on the 20d. I am relatively new to dslr. I have owned film slr's, old and pretty much manual, up until buying a digital p&s 1 year ago. My old film slr had a shoe mounted flash. When taking flash pictures I basically set the shutter speed at 1/125 and the aperature at whatever the flash said was appropriate for the ISO of the film.
I am confused with the settings I am seeing with the pop up flash on the 20d. The camera has the 18-55 zoom lens. In auto at about 40MM the settings are 1/60 and fstop of 5.0. In program mode the same. In shutter priority at 1/60 the fstop is flashing and doesn't stop until I roll back to a shutter speed of 1/8. I was able to bump that up to 1/25 by setting the exposure compensation to -2. In aperature priority it wasn't happy until 1/20 at 5.0 and a -2.
With ttl metering why wouldn't the camera adjust the flash strength so that the shot would be possible at 1/60? Or does that only happen in auto mode? I took pictures of the same subject from the same spot and they are all pretty close.
Would I get better results with a shoe mounted flash?
I was taking pictures of different color water bottles that sat on a table underneath 5 60 watt bulbs in a chandelier. Without the flash opened, in shutter priority, the camera wanted a shutter speed of 3 seconds to get the 5.0 fstop, so it looks like the camera recognizes when the flash is to be used.
