Yes I know the Nikon is a tack slower, still the new Panasonic 50mm f/1.4 lens is really BIG!
Ken Rockwell posted the 24-70mm S lens. The conclusion:
The Nikon Z 24-70mm f/4 S is a compact high-performance ultra-ultra sharp lens for Nikon’s new full-frame mirrorless cameras.
It’s tiny and optically excellent, so it’s the best lens you can get for you Nikon Z now. I’d not bother with an SLR lens on the FTZ, which is going to be bigger and have lower performance. If you’re going to use a Z body, get the right lenses for it.
What we like:
Good build quality, and nicely balanced on Z6/7
Excellent sharpness at all apertures
Very well-controlled coma
What we don’t
Large by the standards of ‘traditional’ 50mm F1.8 lenses
Costly compared to the F-mount equivalent (but a totally new design)
Not the prettiest bokeh – onion rings and ‘bullseyes’ visible at some apertures and with some subjects
The Nikon Z 50mm F1.8 S is a powerful standard lens for the Z system, offering outstanding sharpness and full-aperture performance. There are better 50mm lenses on the market for portraiture, but none that are sharper or so well-corrected for coma and longitudinal chromatic aberration when shot wide open.
