Some while ago I bought the teleconverter second hand, it remained in my bag unused, I did not get an operating manual with it and have not figured out how to find one on Ricoh Pentax support. It only seems to focus when I pre-focus manually close to the focus point, when it is a long way off it just hunts back and forth without finding focus.
I had hoped to use it with my 300mm DA* on a K5 ii, is it a lost cause? or am I doing something wrong? When mounted I put in the actual focal length 300mm, not 500mm which would be 300 x 1.7
I have the latest firmware 1.07 and it does the same with my K1
