This question already has an answer here:

I have nikon D3400 and an extra sigma lens 70-300mm DL Macro Super. They are not compatible because the lens does not have a built in af motor and d3400 also does not have af motor in it. Is there any extension or adapter that would make these 2 compatible? THANKS

  • I think I have the Pentax version of that lens (adapted to Fuji X) Mine is manual focus. Does yours not have manual focus? – Belle-Sophie Feb 28 '18 at 12:50
