Sony 14mm f/1.8 GM vs Sony 20-70mm f/4 G
It's a trade-off
The Sony 14mm f/1.8 GM and Sony 20-70mm f/4 G differ mainly in focal length — 14mm versus 20-70mm — so the right choice comes down to the field of view you want rather than one lens outperforming the other. The Sony 14mm f/1.8 GM offers a wider f/1.8 aperture, a lighter body (28g less) and closer minimum focusing, while the Sony 20-70mm f/4 G offers a lower price (£126 less). Both share a compatible lens mount.
Our take: If you're unsure, the Sony 20-70mm f/4 G is the safer value pick — step up to the Sony 14mm f/1.8 GM only if you want a broader field of view (14mm), a wider f/1.8 aperture, a lighter body (28g less) and closer minimum focusing.
Which should you buy?
It really comes down to field of view — 14mm versus 20-70mm — pick the one that frames what you shoot.
