[QUOTE="Metal Jacket, post: 602685, member: 43028"] Just checked on my old Sigma 300 F4 and its has a tag which pushes on the button ..D lens ? Maybe not, there is no button on the D7100 and the same lens works fine on that ..... More tests show that the protrusion on the lens moves with the aperture ring and only aligns when at smallest aperture ( f 22) .That makes the feeler inside the camera open the aperture for focusing. With the D7100 etc this must be done electronically as there is no lens mount side button. [/QUOTE]
