Hi.I have bought a used SB-22 for my F3P mainly (Hope to be able to use it-very occationally-on my Pentax 67).Since the manual wasn't shipped with it,I have a few questions for you out there: 1)What does the functions (a1,a2,md,m,ttl) stand for,how do they work,and is it possible for the F3 to utilize ttl blitz-metering?When I turned on that option,a red dot started to blink in my view-finder which on the other modes was constantly on. 2)There is also a light which reads bounce.Is it only a warning to compensate aperture for the greater travelling distance,smaller amount of light reaching the subject,or does it have a function? 3)Is there an online manual for this blitz? 4)Is it possible to use it on a Pentax 67?I guess it will,but it is always nice to hear from folks who have experience:) Thanks in advance.
