Take a look at the view from Sony's new ultra-wide zoom, paired with the 60MP a7R IV. The 12-24mm F2.8 GM rounds out a series of F2.8 constant zooms, joining the existing 24-70mm and 70-200mm in the high-end 'G Master' lineup. It's a touch wider than Sigma's 14-24mm F2.8 but more than double the cost – check out our samples above and see what that extra-wide view looks like.
