There is normal wear and tear from using this camera for a couple years but nothing extreme or out of the ordinary. I have found that the rear mic port (port 2) only works with certain types of mics like Rode NTG-2. A Sennhesier and Sony mics that I've tried haven't worked in port 2. I cannot guarantee the rear port 2 will work with your mic. I'm not sure what the problem is, perhaps a firmware issue. The front port 1 has always worked flawlessly with any other mic I've ever used. I have also had intermittent autofocus lock while filming with this camera, specifically when it is racked in all the way the camera simply will not focus. Everything else on this camera functions correctly and I've never had any other issues. 

There are absolutely no scratches on the lense. I have a UV filter over it 100% of the time so it was and has always been protected. I will leave the UV filter on the camera for you. 

This also comes with 3 batteries and a charger and well as all the manuals that come with it from the manufacturer.
