I have a sigma 150-500 lens.I have had to send it back to sigma 3 times (it seems to happen every 3 mo.)to repair the main pcb.It was one on the recall list.I got it back last thurs. used it 3-4 times and twice the shutter has stayed closed and will not open untill I turn the camera off.Is this a lens problem or my camera? I don't want to call sigma and raise holy heck if it is not the lens. I have a nikon d90 and d50 and use the lens on both of them.
thanks! |
