I lost my lens to my 100-400mm on a trip and I am in need of a new one. What size lens cap fits this lens? Also, what size lens cap fits the 18-135mm?
100-400 is 77mm and 18-135 is 67mm. They're the same with filter size. You can get the knock off pinch cap from ebay for $5 each.
THANK YOU SO MUCH!
