This is the biggest omission in flash design. WHY don't the just make a small bouncable flash!!??
Let US decide if it is to weak. We have high ISOs now!
I shoot my Sunpak RD2000 in M mode with good results. Use a wire flash tether to.
And only at shutter 1/400 does the lower part of the picture become a bit shaded. At 1/500 lover 10% if blacked out by the shutter.
