D850  10,5mm f/2.8

Erik, I am bringing this old thread to life again as when shaving my 10.5mm, I realized that with the material removed, there is very little left to keep the original cap in place (with the intact shade part inserted) to hold it in place even after adding tape, and I like your approach to this. So on a whim, but without fully understanding the description  , I acquired a set consisting of a 6T and 5T ring with elements (to be removed) showing separation in order to try replicate your filter ring attachment modification,. After receiving the 6T (that differs slightly in the labeling from Erik's) here is my understanding of the dremeling modification that I would appreciates some feedback on. The 6T ring is hereafter just called the "Ring".

0. The retaining ring is loosened and put aside, the optical element is taken out of the Ring not to be used.
1. As the male thread on the Ring would extend too far and cover the focus collar on the 10.5mm, it is to be dremeled off to the base of the ring. (No threads shown in your image on the lens side)
2. The part of the ring that seats the optical elements (not sure how much is left of it after removing the male threads) is too narrow and has to be dremeled down to slightly wider diameter than the female threads of the Ring.
3. The female threads on the Ring might have to be slightly dremeled down a bit to fit tightly over the 10.5mm front.
(Additinoal question: is it to be pushed linearly in, or be fitted by rotating and sort of screwed on the the front of the 10.5mm)
4. Not so sure about this but from the following:

The donor was a Close up nr. 6T filter housing relieved from the glass and the male 62mm threads are used as a spacer inside to make the filter slide on to the lens and position, seat correctly.  A bit of Dremel work,,, and the filter ring slides into position solidly.

The male 62mm threads that are used as a spacer inside, you mean the retainer ring, right?

If used with a standard lens cap, it seems the added filter ring (that has to be added to the Ring) has to be unscrewed at every use unless a circular crop of the field is wanted?

About the shade:

If mounted in a filter ring trimming of the ring is needed

Is this pointing to a regular filter ring opposed to the Ring as the Ring is wider or has already threads partly reduced?

Hope some of this makes sense. Outside and inside of the Ring shown below.

Add me to the positive feedback. It was a great show, full of energy, with an excellent bass and 2nd guitar. He keeps his sound and voice. He may be Old but not faded away

Nice!

All the Neil Young shows I have been to are great and full of energy. He obviously loves to play live
