I went out with a few friends today to take a few pictures. After emerging from my car, I decided to try out the polarizer for my new lens. I tried to attach it like any ordinary filter, yet it did not screw in. Upon closer inspection, I have found that my 77mm Tiffen polarizer came without threading to allow for it to be screwed in! Argh!
I’ll have to contact some people about it on Monday to get a replacement.
