Hi Juan, First of all, keep it FAR from the other lenses, and be careful. If you open it do it on something that will never be in touch with the 'sane' lenses. Being it a KM lens, I think the internal layout would be the same of the 50/1.4. Maybe there is something slightly different compared to the K 55/1.8 but I think not. Somebody surely can correct me on this point. The screws of the mount are usually very tightly screwed in, so you have to use a good cross screwdriver of the right size. I opened a couple of 50 (a KA 1.7 and a KM 1.7, if I'm right) but it was many years ago and I'm not able to remember the right procedure. I tried some days ago to check a KM 50/1.4 that doesn't close past f/16 but I simply was unable to unscrew the mount, so I decided to quit for now. Hope this helps a bit.
