Last night I was out shooting and I changed lenses, and put on my Sigma 18-250 (which has previously worked fine for a good few years) I now get "F--" flashing on the back screen instead of the actual aperature and I can't take pictures.
It seems like it is intermittently and very briefly "seeing" the lens as it flashes an F number every now and then.
Has anyone had this issue and got any ideas of how to fix it? (I've cleaned the contacts on the lens and body) Other lenses are also still working fine. Or is this going to be new lens time?
Thanks
