Just to ad.....
I have lots of Nikon lenses and every lens i have have a filter attached at the front of the glass.....Make sure that u have at least polarizer even if it is cheap polarizer....so that u protect the glass...
Many lenses gets banged up while in a hurry to capture that image and i know i have done it myself so many times...
All my filters are SINGHRAY filters...but that is not to say that other filters wont do the job...
Just get the filter...And u dont have to have filter on every lens ...if the size is the same u can move one filter from lens to lens...Make sure u get filter same time when u get lens or u will never get it later...comon thing
I am just lazy to do that so i have every lens covered with filter...LOL
U wont be sorry beleive me...cause lenses are to expensive to be damaged...
