[QUOTE="TwistedThrottle, post: 745367, member: 46724"] Double check it is set to f22. I know that with my 8mm, since there is no aperture lock on the lens, I usually have to dial it back into f22 after twisting it onto the lens mount because I inadvertently adjust the aperture ring at the same time. My 8mm Rokinon works with my D40x, (which is a pre pre pre pre pre pre d3500) as long as the aperture is dialed into f22 on the lens. Also, are you sure you got a lens that has the CPU contacts? DSLR's need to be able to communicate somehow with the lens either through electronic connection where both lens and camera have electrical connections or mechanical where the camera has to have an aperture feeler gage to detect where the aperture is set on the lens.
