4 months ago I bought an a6300 on ebay. The EVF was so tilted that I carefully inspected the side of the camera, assuming I would see signs of it being dropped. I estimate it was off by 8° counter-clockwise.
3 weeks ago I bought an a6500 from adorama. The EVF was tilted counter-clockwise about 4°. Enough to drive me insane. So i sent it back for a return as defective. I would have done an exchange, but I feared their entire batch would have the defect.
Last week I bought one from K&M Camera. It arrived today. The EVF is tilted counter-clockwise about 2-3°. Still plenty to drive me crazy. I'm sending it back for a return, except I'm convinced that they all have this defect, and I may not order another to try.
