Two Sony 3 fat lenses. The one on the right is the one that comes with the first version of the Sony 3 fat with a single laser, kes-400A, but it only reads Blu-ray. | The one on the left is the one that comes with the rest of the devices which have two lasers. It's untested because it was on a disc reader that doesn't take cartridges. kes-410A | A small note, if you are looking for a lens for the Sony 3, there are only two types: either with one laser or two lasers. So if your device is the first fat version, its lens is the one on the right, otherwise it's the one on the left.
