Only if the whole glass appears yellowish when you look through the lens. It'll impart a slight yellowish tinge to anything viewed through it. I "fixed" a pair of Super Tak 50/1.4's by leaving them out in the sunlight for a couple of months. I put tin foil underneath the lens and put them on my windowsill. After 2 months of this, the yellowing was almost completely gone. -Mat -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
