| p.1 #1 · sigma 30 E mount problem/question |
Just picked up a sigma 30. here is my question. when the lens is not mounted, or the lens is mounted with camera off, the aperture is closed, and as I tilt the lens, it makes a clicking sound like things are shifting inside, and I can actually feel thing tilting inside. when the lens is mounted and the aperture opens, the lens no longer makes the sound. Is this normal? has anyone else experience this? if the camera is on, and the aperture is closed down to f22, it still does not make any noise.
can someone who owns this lens test this and see if its normal? thanks.
