I am looking at buying a flash for my 8008s and I want to make sure I get one that will work with the N90s which will probably be my next camera. Will the SB25 give me the same functionality on the N90s as it does on the N90? Or should I look for the SB26? Also...If I save a few buck and get the SB24...will I miss anything besides the fast 1/4000 sync and the 3D on the N90s? Thanks in advance!
