Chosen Solution
Can i buy only the lens and not the Tube. I would like to try to replace it, because of a smear in the coating that i got day 1. I would at least try to change the lens even if it is glued in. If it fails i can replace the whole Tube afterwards. Re: Sry but my Title-question was not precise. I wanted to know where can i get such a lens, here on ifixit i can buy only the whole assembly.
unfortunately, u have to replace the whole tube
Stanislav Bespalko that is exactly the problem. You can get eye tubes but I have not yet found anybody that sells replacement lenses. The only thing you can try is to check sites like ebay etc and see if there are broken VR sets for sale where you can harvest the lens from. Cost will most likely be higher than a new eye tube.
