Anti-reflex paint for lens adapter
« on: March 08, 2021, 22:01:16 »
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.?

Thank you!
The German "telescope-paint" seems perfect......38 Euros + shipping.....expected to cost a bit more than just normal paint......

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.

Was later modified using a black Nikon lens cloth sponsored by Birna, also soaked up the last bit of moisture in the can,,,  ::)

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 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.
