Aut cum scuto aut in scuto
That is one rule I took took literally. I have a UV filter on all ofmy 8 lenses and a circular polarizer for every filter thread size.The UV filters are a cheap investment that can save you a lot ofdough if you drop a lens or a camera.The polarizing filters are great for shooting reflective imageslike choppy waters on a bright day or anything behind a glassstorefront, but in larger sizes, they get expensive. An 86mm Circularpolarizer for one of my lenses was two hundred and change.
Try one of the rubber strap wrenches. Not a lot of surface area on a filter to latch on but it will provide a solid grip.
Ran into this problem a while ago. We didn't get the filter wrench from Amazon, but the wrench set looks much the same. https://smile.amazon.com/Neewer-Rubber-Coated-Remover-Fujifilm-Panasonic/dp/B018I848Q2/ref=sr_1_3?crid=2BWS6EYPQCQDG&keywords=camera+filter+wrench+set&qid=1566233452&s=gateway&sprefix=camera+filter+wr%2Caps%2C137&sr=8-3
Remove the glass first, then go for the strap clamp as mentioned.
No rubber strap wrench handy?Try the camera carry strap. Usually works.
Real men use a hammer :-)
Used to work at a camera shop. Remove the broken glass, grab the the filter ring with the tip of needle nose pliers and twist the filter ring. It will collapse and come off
What he said. BTDTGTTS. The filter did what it was intended to do and hopefully turned the energy into its broken glass.
Hope that the mount isn't torqued, or the mirror box misaligned, from the impact. I'd say "ask me how I know", only that's pretty obvious. Nikon service will tell you that you shouldn't have used a Tokina lens :-)Good luck!
...Tokina lens...Why? Do Nikon lens know how to duck?
