Thread measurements of my new wide angle lens?

Question

I just bought a Digital Concepts 72mm wide angle lens with macro for my Panasonic DVX-102BE. I want to attach the wide angle lens without having to put the macro on as well, but the wide angle has slightly smaller threads, so, its too small.

Nowhere on the box or in the bit of paper it came with does it tell me the measurements of the threads for the fisheye on its own

Anyone got one of these lenses, or wanna find out the measurements for me? I guess itl be around 68mm??

Answer 1

have a look in the rim of the lens it fits on.  it usually has the size there so you know what size ring to get for say Cokin filters
