These lens mounts are supplied complete with filter holder mounting bracket, lens disc, and lens disc attachment screws. The lens mount will be supplied with a #421-001 Lens Disc with 39mm hole unless a different lens disc is requested. Other lens discs are available to accommodate lenses with 25mm, 32.5mm, 42mm, 50mm, 53mm, and 55mm mounting threads. Please contact us regarding custom sizes.

The used lens mounts may have cosmetic marks from previous use, but are in perfect working condition.

Note: Lens discs are not threaded - a retaining ring or lens flange will be required to mount the lens to the disc. If you require a retaining ring or lens flange, it may be purchased separately.
