The Tamron 20mm F/2.8 Di III OSD M1:2 is the ideal ultra-wide-angle lens for any photographer. It is a lens for anyone wanting to travel light. The fast 2.8 aperture allows picture taking in low light and the use of low dispersion glass and glass molded aspherical lens elements provide outstanding optical performance. One of the key features is the ability to take pictures as close as 4.3 inches from your subject. This close-up feature will allow you to take pictures that show the unique perspective of ultra-wide-angle lenses.

Q: Would this lens work with a Sony a7iii?

A: Yes! I have the next model up, which has the same lens mount and full-frame as the a7iii, so the Tamron 20mm will work just fine.
