Tamron 16 30mm f 2 8 di iii vxd g2 vs tamron 20 40mm f 2 8 di iii vxd?

These two Tamron zooms both cover full frame, both have f/2.8 and autofocus, and both fit Sony E and Nikon Z. The difference is the range.

The Tamron 16-30mm f/2.8 Di III VXD G2 is the wider of the two. It's the one I'd pick for big skies and strong foregrounds, and at 440 grams it doesn't extend as it zooms. Its APS-C view is like 24-45mm.

The Tamron 20-40mm f/2.8 Di III VXD starts a little tighter, so it suits street and documentary work where you want to stand back a bit less. On APS-C it frames like 30-60mm.

If you shoot landscapes, go with the 16-30mm. For everyday mixed use, the 20-40mm is the more general choice. Neither has stabilisation, so check the lens guide before you commit.
