I have this RAF-Camera adapter and when using it especially with flash I get flare.
Image attached shows how the internal of adapter seems to reflect light and I think this causes the flare.
Are there any good "DIY paint" you can use for making the internal of the adapter "anti-reflective"?
Think many adapters does not have the best anti-reflective inner surfaces.....?
-
Gluing some black velvet fabric could be an alternative solution ?
-
Yes, maybe.....some kind of thin black felt?
I think for this conical shape......maybe paint will be easier....?
What does Nikon use for the internal parts of cameras, lenses etc.?
-
I only Googled, but there do seem to be solutions (pardon the pun)...

A good search term is: https://www.google.com/search?client=safari&rls=en&ei=spRGYMX1MKrfmAX1rq8g&q=flat+black+paint+for+telescopes&oq=anti+reflective+black+paint+camera&gs_lcp=Cgdnd3Mtd2l6EAEYADIHCAAQRxCwAzIHCAAQRxCwAzIHCAAQRxCwAzIHCAAQRxCwAzIHCAAQRxCwAzIHCAAQRxCwAzIHCAAQRxCwAzIHCAAQRxCwA1AAWABgvGVoAnACeACAAc8BiAHPAZIBAzItMZgBAKoBB2d3cy13aXrIAQjAAQE&sclient=gws-wiz

Thank you!
The German "telescope-paint" seems perfect......38 Euros + shipping.....expected to cost a bit more than just normal paint......
-
Maybe also this could be an option:

Ordered a small can of the "Albrecht" paint from Gerd Neumann.......
-
I have used Humbrol #33 Matt Black for years for that application, also doesn't shine in [IR] Cost 2€ lasts for years.
It's also possible to buy "Lens Flocking" with sticky backing - purpose made for that application.

First image in this post by JA indicate 'a lot' of internal reflections :o

Was later modified using a black Nikon lens cloth sponsored by Birna, also soaked up the last bit of moisture in the can,,, ::)
-
Aha......a hole-camera using a beer can as lens?
I found the #33 paint locally....can try that also......

I don't know how durable this paint is, but it is very very black.

Seems like it would be a good option.
-
Yes, Pinhole camera using beer can ::)
Remember to stir the paint a very long time, you really need that to get the flat matt effect from Humbol Matt paints - I would say about 5 minutes and out in all corners of the little can!
-
Ok......that was a long time....but probably to get all the pigments even distributed in the paint.......
-
Ok.....that is "black".....I go with "Albrecht" and Humble #33 first and see how this works......probably most adapters we buy to use 3. party lenses could benefit from this.....

The Humbrol enamel is going to be more durable for sure.

It helped a lot with the flare after the lens tube got its internal painted with matte paint.
If the internal of the tube had circular grooves like we normally see on cylindric tubes the refleksions would be less I think.
Don't know if a cylindric tube would be better than a conical to have less internal refleksions?
-
I have a similar conical RMS to L39 adapter, and I painted its inside with the blackboard paint.
Unless you need a tiny lens to stick into complicated places to shoot subjects, a cylindrical extension tube could be less reflective, because the part right behind the attached lens is away from its rear optical element.
