My 45N-2 has no detents at all except for the sort of detent that consists of two pins that pull in to release the front tilt. I honestly think I am better for it, I always double check things anyway before putting a loupe on the ground glass and it makes tiny adjustments a breeze. I have used two other field cameras that had detents and I always found them to be somewhat of a disrupting while engaging in view camera movements..
