Hi, I am Antonio, from Italy (sorry for my english..)
Like other people I started to have some problems of separation with the secondary mirror of my tamron. Being a chemist in life, I have unglow the mirror using methylene cloride (if someone have a question, I am here!). Until this point all ok: the primary lens into my left hand and the secondary mirror into my right ha... NO! It is fall down to the ground and broke...

So if someone have one broke sp 500 secondary mirror to send me (obviously paying) I would be happy: I have tried to contact Tamron Itay, Europe and Japan but they have not nothing, not more.

Thank you all
