Hi,
First post here so hello!
I've got one of these lenses which I purchased used along with an AF101.
It seems a great general purpose lens and the images look really nice but I'm having a few issues with pulling focus. I'm finding that it can be quite 'steppy' or judderry when pulling focus between different distances, and I can see the focus scale on the lens 'hopping' rather than moving really smoothly as if it's fighting some resistance. It also seems to be variable, sometimes it's smoother than others. Being focus by wire I'm wondering whether this is just an unfortunate function of the lens or whether it has a fault? It also makes a bit of an electronic whining sound when the camera is running (but the OIS is switched off).
I'd be grateful of your thoughts...
Thanks
