>>3508483I think its just the k-30
Its flash housing protrudes a lot and wont allow the 500mm f6.3 to mount, the 1000 f10 mounts without a problem.
I think I can just sand or cut away 2mm and ruin the resale value of the camera, not that this model has any thanks to the black frame issue that plagues it.
On the other issue is extremely easy to make you come out from anonymity just by making a post about mirror lenses :P
