Subject: [Leica] IMG: Takumar in the Sunshine

My slightly radioactive Pentax Super-Multi-Coated Takumar 50/1.4 is 
undergoing a sunshine treatment in hopes of reducing the slight 
discoloration of the 3 rear elements.  The recommended exposure is about 
a week, but may get extended because of bad weather days. You may note 
that this photo was taken with with a Takumar 55/1.8, which also has 
Thoriumdioxide glass, but is not discolored enough to notice.
