So, using a Pentax 67 helicoid for focus I fabbed with a carbon fiber tube to adapt to a mount scavenged from a defective pentax 67 teleconverter. The lens came with a robust aluminum threaded mounting bracket. So a tube I could tap into, this was fabbed from CF and epoxy. I spent way too long on that part. Learning experiece. I already had all the P67 to EF and EF to nex adapters. I will add some photos after a I get a chance to use it a bit.
