if any of you want to releive yourselves of these flash guns let me know i am needing another one for some strobing stuff.
i use one to good effect both on a 400D and 50D body. they are great but you can use any mode but TTL
I use mine as a basic bounce flash normal settings are f/2.8, ISO 100, sync (shutter speed) 1/250s. I use Av mode and manual flash power at 1/2
