Can I use my old Ricoh XR Speedlight 400 safely with my Nikon D5200?
Chris says… The worry about putting old flashguns on newer SLRs is that the trigger voltage used by the flash could be much higher than modern circuitry can deal with, which could lead to an expensive repair. Not all old ’guns have this problem, but I can’t find a trigger voltage for yours to be sure it would be safe.
Using the Ricoh on the hotshoe may be of limited use anyway, as you would be forced to set up everything manually. Instead, I would recommend a more modern strobe. My top choice would be Nikon’s SB-700, costing £225/$330.
Don’t throw away your Ricoh, though. These old ’guns are great for strobist set-ups, when used remotely and fired by a wireless trigger.
