May I ask what is the difference between a cylindrical lens hood and a flower hood? I don't mean the shape but rather, what are their difference in terms of usage? From what I see, the normal cylindrical hood seem to be better, but if so, why are so many camera manufacturers providing flower hoods for their cameras instead (e.g. Pana, Sony etc)??
Would appreciate it if some knowledgeable person here can enlighten me.
Thanks in advance!
