<p>This is actually the old 35mm summicron v4 pre-asph! probably because i brought this to the alps....but the temperature difference wasnt that bad i thought. I have sent to Mr. Lin in taiwan and I saw his experiences in repairing separation of lenses and he also fixed few of the exact same summicron 35mm before. I will show you here all the photos I got after scanning the films. It doesnt happen in every single photo but sometimes it shows up as straight rainbow like lines on the right side of the photo.</p><div></div>
