Sony fe 20 70mm f 4 g vs tamron 17 50mm f 4 di iii vxd?

Both are light f/4 standard zooms for Sony E full frame bodies, and neither has stabilisation, so the choice mostly comes down to framing.

The Tamron 17-50mm starts wider, which makes it my pick for landscapes, interiors, or anywhere you want more room around the subject. The Sony 20-70mm gives up a little width for more reach, which suits everyday shooting and portraits.

On APS-C, the Tamron frames roughly like 26-75mm and the Sony like 30-105mm, so the Sony still has the longer reach.

Both hold f/4 across the whole zoom, so exposure stays steady as you zoom. If you're building a first kit, a standard zoom like these is a sensible place to start. Choose the Tamron for wide views and the Sony for reach.
