I am currently in the market for some new equipment, one (minor) item of which is a 62mm Nikon circular polarizer, I also want to get a lens cap to fit. Not knowing the outer thread size, I just stated the requirement and let the potential suppliers come back. These are the responses: B+H : Not available Adorama: $8 M&M: Visit Wal-Mart and check out the tupperware pot lids. Comments? Andy Shaw
