A rather simple filter adapter for the ISCO UltraStar anmorphot. Should work with on all of these small versions (regardless if red or golden). These are needed to for screw-on diopters or something as simple as a lens cap.
!! These adapters are not finished and still need threads, you get them with either an empty UV-filter or a stepper ring !!
There are two versions, bot will have a really tight fit. Depending on your print need some sending to fit at all! Use some strong glue to attach your threads, I use epoxy
V1 - basic (and boring) design for 72mm filters - designed with the Tamron A9F +0.5 diopter in mind - you need an empty 72mm UV filter for threads
V2 - more slick looking, newer design for either 72mm, 77mm or even 82mm filters - takes an empty 77mm UV filter for threads - takes 77->72mm step-down ring for threads - takes 77->82mm step-up ring for threads
Again: use a strong glue (like epoxy) to secure your filter-threads to these adapters!
and btw, I laughed out loud at the disgusting HDR-pics my phone took, so I left them in :)
