+[title] Iris lock at a fixed value
+[* black] If you have removed the iris gear to lock the F-value, I suggest to lock the iris ring with some small pieces of adhesive tape. You can see 3 of them in the 1st picture.
+[* black] I decided to set the iris at f:4. The open iris has a diameter of around 11.5mm, so I closed it to 6.7 mm (I used a digital caliper to measure ) and then I locked the ring with some tape.
+[* black] In the 2nd picture you can see the final result.
