Great guide! This worked perfectly for me getting into and out of my S100. I didn’t have a replacement lens assembly though so I went deeper and pulled the assembly apart to see how it worked. Have you ever done that, and successfully revived a lens assembly that seemed high friction?
Reassembling the lens assembly was like a 3D puzzle. Had never seen anything like the helical guides inside the lens before. I wasn’t able to make the assembly work again but its failure mode is different now haha. Was previously no motion, lens error. Now it edges open over 3 tries then closes itself on the 4th try. Progress, maybe? Thinking of trying a bit of grease. Or a new lens assembly.
