With that said I use both Nikon and BW filters and I do not like using adapters or swapping filters in order to minimize thread damage that may strip them.
FYI, the filter thread on the lens is a lot stronger than we think - they are really not that flimsy. I work in a camera store with an inhouse repair facility and I have yet to see a lens with damage filter thread. We see a lot of filters being stuck on the lens and help remove them. Here are the 3 most common scenario:
1. Filter screwed on too tight (usually a woman will bring this problem to us because her gorrilla BF or hubby put the filter on for her!) or while it's hot (left in the sun in the car) and when cooled down with filter on, it's seized. This can usually be removed by using a filter wrench (buy one on eBay if you don't want to pay us $10 to do it for you.) or put lens in zip lock sandwich bag in the freezer for 15 mins and filter will unscrew. (Nikon repairs told us to do this - yes they did and it works wonderfully.)
2. Filter screwed on in a hurry and got cross-threaded. In minor cases, if there's still room to put a screw driver between filter and lens lip, we put a thin screw-driver in the space and twist till we hear a pop and lens thread falls back in place and unscrews very loosely. If that doesn't work, in severe cases, we break the glass on the filter, use a needle-nose pliers and pull in the rim of the filter (without the glass) and then remove the metal rim. Again $10 plus sell another filter!
3 Worst case scenario, lens "gently" dropped on hard surface landing on the rim bending the filter and so cannot be unscrewed. Remedy same as (2) above - break glass and use pliers to pull in metal rim then unscrew.
But in all cases, I have never ever seen the female thread side on the lens being damaged. Our store also is a pickup point for Borrowlenses.com which rents out expensive (and not so expensive lenses) and we asked if they have any problem with filter threads damaged by renters - the answer is no. So, there you have it - don't worry. The filter threads on the lens are much more durable than we imagine.
