A: There does not appear to be any sort of screw for mounting another lens on the front of this one.

Q: 8. When stopped to the highest setting (5 stops) does the image degrade (sharpness, cross hatching)?

A: I've shot extensively with the 95mm, 72mm, & 67mm versions. You don't get any cross-hatching, but a definite vignette in the corners toward the 5 stop range when shooting photos. Video is not an issue as it crops to 16:9. Other than than, negligible colour cast & no sharpness issues.

A: I don't have this filter. Not sure why I was asked by BH to answer the question. Sorry.

A: definitely not!! the rear thread of the filter is 95mm, however the front thread of the filter is 105mm
