It's a trade-off
The Sony 10-20mm f4 PZ G and Tamron 28-75mm f/2.8 Di III VXD G2 differ mainly in focal length — 10-20mm versus 28-75mm — so the right choice comes down to the field of view you want rather than one lens outperforming the other. The Sony 10-20mm f4 PZ G offers a lower price (£114.58 less) and a lighter body (362g less), while the Tamron 28-75mm f/2.8 Di III VXD G2 offers a wider f/2.8 aperture and closer minimum focusing.
Our take: If you're unsure, the Sony 10-20mm f4 PZ G is the safer value pick — step up to the Tamron 28-75mm f/2.8 Di III VXD G2 only if you want a wider f/2.8 aperture and closer minimum focusing.
It really comes down to price versus aperture — pick the one whose strengths match how you shoot.
