Help !
I'm stuck repairing my Canon FL 19mm 3.5.
I can't remove the second front lens.
So I'm looking for a helping hand or a repair manual for this lens.
Can someone help me ?
Thank you in advance and have a good evening!

This is not a lens I've worked on in the past, but here is what I suggest based on what I can see:
In picture number one, there is a small hole in the center just above the black front ring. Is there a set screw in this? If so, and you remove it, you may be able to rotate the black front portion until it unscrews, in which case, the second element may insert from the back.
Typically, when you see a seam between two colored sections, one can be removed from the other, so even if there is no set screw, it may still simply rotate out. If it is too tight to turn, heating the lens might help. |

This looks like it should be helpful. It does seem to indicate that the entire black portion comprising the front cell of the lens (part A in the second illustration) screws out. It doesn't explode the cell into individual elements/retaining rings,though. Is there another illustration that does so? If so, it can let the OP know whether the element in question is set in from the front and the back, as well as the retaining ring configuration holding it in.
