Q: 3. I was gnderin what is the function of two screws that are on the filter? I've realized the range was limited and I thought something was off. Then I unscrewed them and having the ability to turn the top glass 360 degrees, now I have full range of Nd, and it saved my life. I figured the glasses are not detachable. So, now I am confused about the function of those screws. They put hard stops for sure but those hard stops were limiting the actual range of the filter. Either mine was a faulty one, or there is something else.

Q: 8. I read a customer review in Amazon which indicates that this filter does not fit the canon cap for the EF 24-105mm lens. Is that true?I currently own 2 L-class canon lenses the EF 24-105 f/4 kit bought with Canon EOS 6D and the EF 17-40 f/4. Both need 77mm UV filters. I have already had two (2) non-heliopan 77 mm filters ,but want to upgrade to Heliopan filters and want to make sure they fit my canon lense caps.Thank you for your answer

A: As these filters are slimmer than most, the front thread may not necessarily grip a clip-on lens cap. You may want to try a screw-on cap instead:Sensei 77mm Screw-In Metal Lens CapB&H # SELCM77 Mfr # LCM-77
