jim_momary Posted February 20, 2008 Share Posted February 20, 2008 Purported to have an 8V synch voltage. see - http://www.botzilla.com/photo/strobeVolts.html 8V is fairly low and fairly safe. IMO. Jim M. Link to comment Share on other sites More sharing options...
Michael R Freeman Posted February 20, 2008 Share Posted February 20, 2008 "8V is fairly low and fairly safe. IMO." I would say 8V is COMPLETELY safe. Nikons can handle up to +250V on the sync circuit. Link to comment Share on other sites More sharing options...
Jerry_ Posted February 20, 2008 Share Posted February 20, 2008 It is a chance. The Wein folks make a 'safe' connector that protects the camera for about $50.00. If *for any reason* you cook the D40 circuits with your Sunpac flash, Nikon will not fix it under warranty. Link to comment Share on other sites More sharing options...
frank_skomial Posted February 21, 2008 Share Posted February 21, 2008 Get Nikon AS-15 hot shoe to PC adapter, at about $15. Set D40 in Aperture priority and turn the Auto ISO to OFF. Set 622 to Auto, and set Aperture and ISO values on the flash that match your camera settings. Link to comment Share on other sites More sharing options...
