The rear element of a lens has some peripheral haziness on the front surface (inaccessible when the lens is fully assembled). Based on lens diagrams, I believe it is between the two rear-most elements, but I cannot figure out how to separate them from the housing.
What is the likely cause of the haziness? Since the haziness is peripheral and on the rear element, what effect is this likely to have on images? If I cannot separate the elements (because they are stuck in the housing), can anything be done to clear it up?
The lens is a Kiron 28-105mm f/3.2-4.5 Macro MC. When I first examined the lens, the haziness appeared to cover the entire area of the front of the rear element, though it was definitely worse peripherally:
After disassembling the lens and heating the rear lens group, the haziness seemed to shift, or lighten, to cover only the peripheral portion of the lens. It also didn't look quite as bad as before.
