YWP - Lion Country

From todays visit to Yorkshire Wildlife Park, these are from "Lion Country".  This is the first time I have used my 100-300 lens (35mm equivalent to 200-600mm).  I also used my new GX80 for the trip but had a number of total lock ups (at least 10 times) and cannot be used again until the battery is removed and put back in, so I will be sending it back for a refund.  I am a little bit reluctant to let it go as it is a great camera (when it doesn't lock up).
