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.
It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena; whose face is marred by the dust and sweat and blood; who strives valiantly; who errs and comes short again and again, because there is no effort without error or shortcoming; who knows the great enthusiasms, the great devotions and spends himself in a worthy cause; who at the best, knows in the end the triumph of high achievement, and who, at worst, if he fails, at least fails while daring greatly; so that his place shall never be with those cold and timid souls who know neither victory or defeat.
