Hi, No I cannot tell you that but I have a samyang 8mm fisheye with a Pentax bayonnette and the aperture is controllable from the body (one small contact is visible on the mount) in Av mode with aperture ring set to A and therefore gives auto exposure in that mode! In the leaflet it also mentions that Nikon has a certain facility to do the same,other mounts have nothing, AFAIK. But obviously this applies to the 8mm, the 14mm may be different! PS. The 8mm is marked Fisheye CS.
