Tamron 75-300mm lense quit focusing??
Check you have not switched camera t manual focus...if it's on auto then try changing various focal lengths to see if it kicks in....if it does intermittently you may have a cracked flex cable...this eventually happens with long throw lens because the cable gets weaken as it stretches and closes.It is also possible the ribbon became dislodged at the Circuit board just behind the mount.
