Hi! I have an F90 and SB-22 speedlight. When I use TTL mode to shot something in the dark, the results often come out over exposed. This happens even when the object is in the center. I am thinking about upgrade to a brighter speedlight such as SB-28. Does anybody know if F90 (non-s) will work well with SB-28? Such as the functions of 3D Multi-SEnsor Balanced Fill Flash High-Speed Sync up to 1/4000 Red-eye REduction etc. Thanks! Koling
