Not only do I have an adapter that lets me connect any flash of indeterminate voltage to my dSLR, but I had full tilt and swivel functionality from my existing flash.
I got the idea from the Strobist blog, which I've been wading through of late. I've decided to start using an external flash with my dSLR because I haven't been happy with the in-camera flash: it's too weak and it can't be effectively used in automatic mode with the manual-focus lenses I've got. What's more, some of the photography I've been doing demands more than the in-camera flash's feeble efforts when it comes to fill flash. So here I am.
Being a real writer means being able to do the work on a bad day.
