Hello, I did a search but was unsure about the terminology so I couldn't find what I was looking for.
I purchased a 15-85mm lens a few months ago. This is a very heavy duty, great quality lens. Well recently, I put the camera on a tripod to try and take some product shots (downwards towards the ground). Unfortunately, the zoom wouldn't stay still and kept falling forwards. I couldn't get the zoom to stay where I wanted it.
If I recall correctly, the zoom part was stiffer when I first received it. Is this just a normal wear problem, or am I doing something wrong? Also, any solutions?
Thanks,
Zach
