K-01 & Tamron Lens. Need your help.....
Recently acquired a used Tamron 24-135mm lens. One thing I am noticing is that the pictures taken with auto focus are not turning out sharp. But the odd thing is that when I use manual focus, I not only get much sharper pictures, but also ones with very different shutter speed, as per EXIF data.
I have two questions:
* Why the difference in shutter speed, when all I have done is changed focus from auto to manual? The focal length, ISO, etc., is staying the same.
* Do you think the auto focus issue can be fixed with fine adjustment technique?
