This ZEISS Distagon T* 18mm f/3.5 ZE has seen better times...

I have here in my hand a Distagon that was sawn in half for demonstration purposes, as seen at the Amsterdam Photo Academy this morning. On the one hand, I found it fascinating, but on the other hand I thought: this is such a waste! (Then again: you end up with two of these...)

I'm trying to figure out which lens I want to do that with. But not something like that.

But how?
I got a lot of Helios 44 lenses 😉

How? some sort of abrasive saw.

Wonder if I could get an abrasive blade for my portaband...

I saw a video of them doing this with a Nikon lens, and it was a diamond blade on a bandsaw with coolant, so you really have to flush it out afterwards. You can also do it with a water blade, but it's a bit rougher cut. https://www.youtube.com/watch?v=DRyVeyD1muM
