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
