So I've sat on my 120-300 2.8 OS non sport for over a year now without using it but for one baseball game. Since getting the 200L I just have had zero interest in picking it up. Well sitting for so long without use evidently caused the OS unit to fail... and It's been like that for several months. I had intentions of selling it but never really "Pushed" selling it. Well I decided that in order to sell it I must repair it. I don't want to sell it non functional. So off it goes. Over the phone Sigma basically said the OS unit was $200 itself plus labor and will also check everything else as well. Not sure if this will hold it's resale value or not but I just don't feel like selling anything broken.
Plus... Still up in the air if I should even sell it or not. I could offload the 200L keep the 120-300 and pickup the 16-35 2.8 III, 24-70 2.8 II and 400 2.8L but then I'd need to get bigger bags.
