Definitely
Though I can probably think of other monstrosities...
I currently have an old zoom lens from an old 8mm Kodak movie camera that had a pretty surprising amount of fungus growing on it (I didn't know it could make mountains!)
The lens is afocal, I will try and make it fit on my Nikon, probably using another camera's taking lens as the base... a monstrosity for sure.
But I don't know if I'll make it in time as it's a pretty complex build....
