Nikon lens adapter for the new Sbig CFW-10 filters wheel, selfbuilted with a standard Sbig nosepiece adapter; I placed on it a bayonet mount that I removed from a Nikon extension ring set (model K), it's simple only 4 drill but the lens is free to turn..(!!!) Overall thickness is 8 mm, I made a test with the 300 f/4.5 lens and work great, an example here. |
