tamron 11-16

Hi all - first post so be gentle. ? I have moved from a Nikon D5300 (Crop) to Sony A7 iii Full Frame. I used a Tamron 11-16 DX on the Nikon and want the same sort of angle of view on the Sony Question is do I need to do any calculations on the numbers ? As the Tamron 11-16 has a 'DX' rating...
