This is a brand new fully coated optical glass filter made in JAPAN. It is top quality, as good or better than big brands like Hoya or Tiffen but these two companies do not make 43mm color filters anymore, too bad. The rings are threaded front and back, made of metal not plastic. The glass is top quality Optical glass with anti-reflective coating on both sides.
Search my storefront to see the other Canonet items I have listed.I have a lot of NEW old stock from a major purchase. It's going fast though and 48mm accessories are not manufactured anymore. Get it while you can. Just because it's here today doesn't mean it won't be gone tomorrow.
Soft Focus is a mild softening filter, very much like the diffusion but about half as strong
