I read in the Oculus subreddit that the focus distance of the DK2 was 1.3 meters, I hadn't heard this and wanted to check. The distance is probably not fixed at exactly 1.3 meters but there's probably an interval where things are in focus, but that could also depend on the apperture set on my camera.
Looking at this, I did have a hard time getting the camera in the sweet spot, haha. 80 cm seems sharper than 130 cm but it's hard to tell. I redid this video three times but it still is kind of crap, sorry about that :P I think the conclusion is at least that focus lies around 1 meter somewhere, and not at infinity :)
Note: Lenses used were the A-lenses, the ones originally on the headset.
