Thank you for you all guys in here, especially with the trials and error, all the effort, Gutta, Scorpio/Michael etc.
Now I am using Michael file to order 3D print, it is cheap, only 3.5usd here, I order 2 pcs for reserve
(because it is cheap).
It will be ready in the next 2 days, finger cross, I hope I can do all the mod.
As the owner of DA200, DA300, DFA150-450 and DA60-250, I really want to get rid this lens, but my several trip really teach me to hold this DA60-250 instead to replace it with DFA 70-200.
DFA70-200 F2.8 is as big as DFA150-450,-- they are not for travelling lenses, but DA60-250/F4 is.
Btw, DA200 and DA300 are the fantastic lenses on K1.
Now my K1 is going to Ricoh Japan to upgrade to K1ii, repair the crack because I dropped it and replace the scratch focusing screen, it cost a lot, but I am willing to pay, because I love the IQ of K1, it will take 2 months.
I am very happy, my camera is repairing in Japan !!! it takes time, but me it is no problem, I want the Japanese/Ricoh Japan service, I am more confident with them.
