Panasonic lumix s 14 28mm f 4 5 6 macro vs panasonic lumix s pro 16 35mm f 4?
Both are L-Mount zooms for full-frame cameras, and both are autofocus with no stabilisation. The difference is in the framing and what each one is built for.
The Panasonic Lumix S 14-28mm f/4-5.6 Macro goes wider, to 14mm, and carries a macro label. Its aperture drops to f/5.6 as you zoom, which matters less for landscapes than for close work.
The Panasonic Lumix S Pro 16-35mm f/4 stays at f/4 across its range and is the one I'd pick for landscapes. As I say on the landscape page, a wide zoom like this is the classic choice for big skies and strong foregrounds, and f/4 is plenty when you're stopping down to f/8 or f/11 anyway.
If you want the extra width or close-up work, get the 14-28mm. For most landscape shooting, the 16-35mm is the better everyday lens. For a quick refresher on what the focal lengths mean, see the focal length guide.
