HOWTO: 105mm f/2.5 AIS infinity adjustment?
« on: September 30, 2024, 22:18:03 »
Is there a way to adjust/calibrate the infinity focus for the 105mm f/2.5 AIS?

I stripped and cleaned this lens and it only occurred to me upon reassembly and testing infinity that I didnt know the technique for this - thankfully reassembly aligned with all my helicoid key and other marks and inifitiy was good


BTW, I found helicoids required a really thin layer of JHT#10 grease otherwise it was really tough to turn.
