Thank you for the advice. I’ve checked and the aperture isn’t working. I’ve been tricked by the seller :(

Hey guys! I've got my father's Canon AE-1 but the FD 50mm f/2 (Bayonet mount) that came with it is filled with fungi now and the repair shop didn't wanna risk breaking the lens down to fix. So! I've just bought another FD 50mm f/1.8 S.C. (breech-lock) to replace to old one but when testing, the shutter is only released half way and would complete only when I turn the breech-lock off and pull out the lens. This doesn't happen with the other FD 50mm f/3.5 macro (Bayonet mount). Does anyone have any idea what I should do in this case? Is there any secrets that I don't know? I thought FD lenses are all the same and I'm pretty sure I turned the breech-lock ring tight and it fits into the camera mount but yeah... Now I'm mourning over my stupidity and the money I spend :'( Thanks in advance!
