Omega #421-170 Flat Lens Mount for D-3, D-4, B, E, and F Series Enlargers

This flat lens mount can be used with Omega D-3 and D-4 4x5 enlargers, B-series 6x9 enlargers including the B-3, B-4, B-5, B-6, B-7, B-8, B-9, and B-10, E-series 5x7 enlargers including the E-5, E-6, and Super Chromega E Dichroic, and F-series 8x10 enlargers including the F and Super Chromega F Dichroic. In some applications the 421-170 lens mount supersedes the older #421-150 lens mount. Please refer to the enlarger manual or our Omega Enlarger Guide to confirm that this is the correct lens mount for your application.

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 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.
