dude I hate you 😀
uhh, if you can't work things out with Ethan, I have a 12mm that I could (somewhat reluctantly, but whatever) possibly post over to ya.
as for checking the camera, make sure you check 1/1000 for capping (can occur if you push the shutter release slowly- try that) and make sure you check the finder for separation or anything like that! finder overhauls are like ~$300 or something.
and adaptors... I got mine off fleabay for like $10 from some guy in HK. it works pretty okay.
good luck and enjoy!
