An ugly discovery...

I got a tip from one PF member. The issue may be very local and related to identical identification of Sigma 500/4.5 and 180/3.5 by Pentax cameras. Unfortunately I'm a Mac user and do not have Windows at home to confirm it via PhotoME.

Would someone with PhotoME installed help me to identify the lens numerical IDs of two relatively small jpeg files. I will shoot low quality images with both lenses tomorrow and may email them for identification.
