This is my first question-post. First of all my final goal is to build a simple but functional objective. I was inspired by this video: DIY Camera Lens (I don't hope to make something so neat the first time.)
I decided I shoud start by building my own EF mounts (or rather have a mchinist build EF mounts) and I can't find specific information on the dimensions of EF mounts (body and lens sides) where to start. I know I could always measure the mount, but a comprehensive drawing would be better. Does anyone have some insight on where to find such data on line?
This question popped on my searches up: Mechanical drawings of lens mounts: are they “open source”?, but most answers deal with the opensourceness of the EF mount and not provide any drawings.
Another option I thought of is using one of the sides of extension rings. And only dealing with the thread.
Thanks for your time!
