I purchased a gently used XF 80mm f/2.8 aspherical macro for my X-T5. Not being familiar with this lens but having had experience with the Leica T mount 60mm macro and Canon and Zeiss macros, I was surprised that I felt what might be best described as a loose lens element that shifted when I tilted the lens, even before being mounted to the camera. In manual focus mode, the lens is fine, but there is a distinct “wobble” when the lens is in autofocus mode. I reported this to the company (I bought it from KEH), and they agreed this was odd and accepted it back for a full refund. I just got a replacement lens and the same thing is happening. I’ve never had an experience in which I feel a lens element loose inside the housing. Is this normal? Should I return it (again)?

I use my XT5 in full manual and the actual exposure does not match my viewfinder image. This just started to take place after owning the camera for over a year. I did a reset to factory settings, but to no avail. This is extremely frustrating, and I’m wondering if the metering system is faulty. Thoughts?
