Май е от това, поне в моя случай:
Just fwiw, I remember reading someone who had trouble with camera or lens finish (not Sigma incidentally) and it turned out he stored his gear in a closet that also had mothballs, thus developed the 'sticky' problem other readers wrote in --
Have you contacted Sigma service office for their suggestions?

Преместих обективите в един шкаф, за де не ги видят телефонните техници.
Аааагрх - и от това, както предположихме по-горе :
I had a couple of Sigma lenses with ZEN finish which were stored in plastic bags and developed soft sticky spots. Soft plastic contains plasticizers which can react with other plastic. Have you ever noticed the greasy deposit which sometimes forms inside car windows? It's plasticizer from the vinyl in your interior seats, dashboard, etc. which volatilized and condensed on the glass. If you can smell a plastic, you know something is evaporating. The polyurethane coating used to waterproof nylon in many camera bags often stinks, especially in old bags.
