DIY C-mount lens hoods

[Floris Vanhoof]

Can anyone suggest a type of tubes or other material to make hoods for my C-mount lenses? 

I'm thinking of black, opaque, non-reflective, flexible rubber tubing that would slide over the front of the C-mount lens.

My lenses are 3,3mm 3,4mm and 3,5mm wide.

Any help where to look and what stuff to use is welcome.

ps: I'd rather have a fitting flexible hood then a 3D printed one as 3D prints I can do are mostly reflective and so stiff they will fall off of not fit on if a little too big or small.

Hoods may already exist. Which lenses are you wanting to shade?

Switar 1:1,4 - 25mm H16 RW

Yvar 1:2,8 - 75mm AR

Switar 1:1,8 - 16mm H16 RX

 

My 25mm has a little bump in the outer ring, so might be hard to screw an existing hood on.

Using old third party slip on adapters and shades is probably your best bet. The Switar 25/1.4 takes a 33mm slip on adapter and fits series 5 filters and hoods. Sometimes these things are almost free from local brick and mortar camera shops, if you can get to one. When you get the proper fit, they work really well. Other than that, look around the house for plastic things you can use as shades: 35mm film canisters, pill bottles, etc.

I just tested some inexpensive universal lens caps:

a 37mm cap fits on my Macro Switar 26mm lens

and 43mm cap fits on Macro Switar 50mm lens

 

next up is the plumber store for tubing to make the hoods
