Hi Optimalers. I use a Zeiss FF450IR and lately the keyboard has been freezing and the mirror seems to be a little slow to return. I called Zeiss today and they told me that since last Feb they do not service the FF450's. I was ver dissapointed to say the least! I asked them for guidance about who/where I could get the camera serviced and they told me "to google it". Wonderful idea!! A few years back Zeiss replaced the springs that assist the mirror up-down movement. Anyone has spare springs? I will do the replacement myself if necessary. Any recommendations for who can service this camera? Thank you very much. Fernando
