    Thank you so much for your answers guys! I tried to disassemble and reassemble the FD 28mm but the problem is still there. I attach below the photos for each aperture so you can understand better my problem. As you can see the aperture at f22 and f16 are the same. Aperture ring set to 22 Aperture ring set to 16 Aperture ring set to 11 Aperture ring set to 8 Aperture ring set to 5.6 Aperture ring set to 4 Aperture ring set to 2.8 Aperture ring set to A And this photo shows how I assembled the lens If you can take a photo for each aperture maybe I can compare with mine. Thank you so much

    Thank you so much! I will try to give it another try :) I wish I can find another lens like mine that works so I can disassemble it and step by step compare how is inside... I tried to check online but seems that there aren’t video, photos or manuals about it... Anyone has any website/place/book where maybe I can find it?

    Hi Orsetto, thank you for Your reply. I am using a Canon AE-1. Actually I’ve already checked what you told me and even I already did what the video shows. I will upload a video in a few minutes where actually explain what is the problem so everyone can understand better. I might post a link to the video. Probably I will upload it to YouTube and here I will post the link. thanks to everyone that is trying to help me

    Unfortunately not, I already cleaned the blades. They move free and smooth.

    Haha yeah! Thanks for the reply. No, I know what you mean though. I'm meaning in manual mode, if I move from f22 to f11 there is no change in the diaphragm size but from f11 to 2.8 it opens as it should?

    Hi everyone. I got this lens that have a problem: from an aperture of f22 to f11 (there are 5 stops moving the ring on the lens) actually the diaphragm doesn’t move, is stuck at f22. After that each stops it move correctly. I can’t understand what could be the problem and I've already disassembled 2 times the lens.

    Thanks, I Tried actually few days ago to just open up the top of the camera and give it a little clean. Now it seems it’s working fine and delivery every shutter speed! You might were right, maybe it was just dirty contacts!

    yes, the camera deliver the selected shutter speed, even the quickest ones!

    Hi everyone! I got this problem with my Canon AE1 that sometimes the camera doesn't respect the shutter speed: if I, for example, snap at 1 full second, sometimes can happen that the camera snap like it was settled at 1/500; also I figure it out that if I keep pressing down the shutter button for the entire period of time (like one or two second) the camera . When I press it normally (like you press the button and release it immediately) sometimes can happen that is not respecting the time function, but as I said, if I keep pressing it the camera does her job! I don't know what could be the problem. Hope someone can help me figuring this out! Thanks!
