Hi, was it something I said? over 60 views and no one owns or has used a Sigma 105mm CPL filter. Are they that bad?????
Thanks

A 105mm diameter filter is a very rare size as the lens it would attach to would be enormous and extremely expensive thus the lack of response. A Sigma 150-500mm "only" takes an 86mm filter!

As a rule the Sigma professional grade products are very good.

Thanks for that Bob, it is for the LEE filter system holder, there option for the pol is way over my spending

Considering that most amateur lenses have 67m filters and pro lenses have 77mm filters do you really want all that overhang on your lens to get caught on things?
