Is the sony fe 16 25mm f 2 8 g good for landscape?
Yes, it's a solid wide zoom for landscapes, as long as you shoot it on full frame. At 16-25mm it gives you the wide sweep that landscape photography relies on for big skies and strong foregrounds. Pair it with one of the high-resolution a7R bodies on its fit list, such as the a7R IV, a7R V or a7R VI, and you'll have plenty of detail to work with.
Two caveats. Landscapes rarely need f/2.8, since you'll usually stop down to f/8 to f/11 anyway. That means you're paying for speed you won't use, and an f/4 wide zoom would be lighter and cheaper. Also, on APS-C this lens frames like 24-38mm, which is no longer wide, so it's a poor landscape choice on bodies like the a6400 or a6700.
