Slip Mount

  • Designed for varifocal lenses, wide angle lenses and lenses without filter threads
  • Accommodates standard threaded mounts
  • Low profile and oversize diameter design prevents wide angle lens vignetting
  • Locking set screws and a wrench are provided to secure the adapter to the lens
  • Many varifocal and shorter fixed focal length (wide angle) lenses are not supplied with filter threads due to the presence of a protruding, strongly convex lens element. Our slip mount adapters allow standard threaded filters to be fitted securely to these and a large variety of lenses that do not have filter threads provided.

Ordering Example:

  • Filter: BP470
  • Outside Diameter of Lens in mm: 43mm

Correct Part# is:

  • BP470-S43
