I started making Camera Butter ND filters because I couldn't find ND filters for my GoPros that had high quality optical performance, could be removed and re-used, didn't need any special mounts or brackets, and fit in just about every mounting system. There really just wasn't anything out there that I liked.
I have an engineering and photography background, which I used to start making them for myself - then friends started asking for them, and it just grew from there.
My first filters were made out of resin - they worked well, and were strong, but they didn't match the high quality that you could get on DSLR filters. After a very long time assessing material samples, testing, re-working and prototypes, I finally came up with the current design: super high quality optical glass, a special nano-coating that repels water and fingerprints, and a custom-made adhesive that can be used and re-used.
After being asked by a customer if I could make lens protectors (for when he wasn't using a filter), I came up with the design for the Camera Butter Lens Shields - solid, high-strength tempered glass that is thick enough to be stronger than anything else out there, but retail the same excellent optical properties of high-end optical glass.
Thank you to everyone who supports this endeavor - I truly appreciate the amazing support that I've received from the community. I would not be here doing this if it wasn't for you.
