I want to know about Nikkor 18-55mm lens hood?

They never did and they never were completely engaged with the idea. They never got to make their own propriety lens mount and used Nikon's instead. That would have been very expensive, I imagine.

Anyway, good for them because they have some of the best mirrorless cameras which are more expensive than a lot of dSLRs right now. Their X-Pro series are dSLR-busters especially in the low-light shooting department. To prove they're serious about their mirrorless line-up?

They did develop their own lens mount this time.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
