Originally posted by Adam The Sigma 70-200mm should work, right? Just send it to Sigma first so they can fix the mount on it so that it doesn't scratch the bottom of the prism housing.
I already did (while I was waiting for the K1 to arrive) to be prepared in advance. They sent it back and the mount is just fine, but the lens just freezes the camera.
They told me they updated the FW on the lens and they checked it on another client's K1 and it was OK. Probably that K1 had an older FW than mine (mine is 1.40).
So now, I have to send it in again, this time together with the K1 so that they can load a more recent FW on the lens and check that it will work with my K1... (bummer...).
Hope they will send it back within next week as I'm leaving for Canada in a a few more days and I definitely want the 70-200 with me...
