Raphael, >>>>>>>>>>>>>>>>>> Can someone tell me what's the difference between cable MC12-A and MC12-B ? Are there other possibilities for a remote cable on the N70/F70? >>>>>>>>>>>>>>>>>> The -A is longer than the -B. The -B is about 1 meter long. I believe the -A is about 3 meters long. Another possible cable is the programable MC-21(?), which is more expensive. An MR-3 mechanical release can be used with an ISO mechanical cable, but some functionality is lost. >>>>>>>>>>>>>>>>>> And finally the $1000000 last question : is it possible to use high synchr. speed with the N70/SB25 combo (I mean higher than 1/125)? I've been reading a lot on it (in mailing lists and magazines) and half of the people think it is whereas the rest thinks it's not. Did somenone REALLY succeed having a 1/4000 speed? The problem is that the N70 has been made after the SB-25. So nothing is said on the N70 in the SB-25 manual... >>>>>>>>>>>>>>>>> The N70 does not support sync higher than 1/125. However, I do not have an SB-25. I doubt the high speed sync is available with that unit. Hope this helps, Jim Korczak Pocono Mountains, USA
