Bahtinov mask for Sigma 40mm F1.4 (L Mount) - anyone with a 3d printer?

[a6400]

Hi,

Can't find any Bahtinov masks for this lens and I don't own a printer.

I wonder if there is anyone who could print out one if I would provide the lens diameter?

Of course will pay for it.

Sometimes I feel like I'm focused but it's hard to tell on tiny display on the camera and then it turns out it could be better.

I'll PM you

Try Astro Printer. I have two of their small Bahtinov masks, one for a 55mm camera leans and one (now slightly modified with a short length of pipe) for a 30mm FMA135 scope.

@a6400, did you mean the Sigma 40mm F/1.4 DG HSM Art?

If yes, I designed it and printed a few days ago. It works, tested on Capella. Are you interested? 🙂

Hmm AstroKeith printed for me 2 different ones and both won’t work. 

Can you post a photo of your mask?

I have the EF bayonet version, but it's the same lens.

Vroobel has kindly made 2 masks for me and they seem to work very well.

Big thanks!
