I'm looking for a manual flash to use on the motor grip of a Bronica SQ Ai medium format camera to give me side-mounted flash. I think I've narrowed my choices down to three fairly inexpensive possibilities, but flash is new to me. --- Vivitar 285HV (new series from 2007 onward): This seems to be a very popular unit (along with the pre-2007 version). However, it has no horizontal swivel, and the Strobist site claims the new version is NOT comparable to the original model. They hailed the announcement of the 285HV's return and then when they actually tried it out, they outright rejected it, calling it "total crap". --- Lumapro LP160: This is the one Strobist likes. It costs about twice as much as the Vivitar and Lumapro is a Strobist site sponsor. --- Yongnuo YN565: This costs about the same (MSRP) as the Vivitar but has horizontal swivel and is available directly from a Chinese distributor with around 15% discount and free shipping. What should I be looking at to decide between the three. If I want both horizontal swivel and vertical tilt, the Vivitar is out. If I want swivel and lower price, only the Lumapro makes the cut.
