Here i will show you a test about an old Canon FD f1.4 lense. Maybe many of you guys think that your lense is broken or something. But maybe it isn't so .. please wait and see.
To test the aperture without screwing the lense on your lensemount, is only possible with a SSC "chrome" lense.
A SSC "chrome" lens can fix the "big arm" in one position, without mounting it on. So you can switch through the different f-steps without mounting.

Hmm…it looks like things are taking a while to load. Try again?
