Originally posted by dws1117 I was lucky to find a 1.4x tele converter yesterday. Is it normal for the focus to sound like grinding gravel? What I mean is that when you use either auto focus or manual focus it sounds and feels like there is gravel or some debris in the focus mechanism. When it is off the converter or attached to the camera without the converter everything sounds and feels smooth and normal again. Is this normal or a bad converter?
Camera is K200 and lens is Tamron 70-300 DI LD macro.
Thanks
One possibility: if you gently try to move the the lens while the TC is attached between the lens and the camera, is there a fair bit of movement or is the whole thing quite solid and no movement of any note?
