Nikon Z7 + Nikon NIKKOR Z 50mm f/1.8 S = Lovely
See my Nikon mirrorless wishlist.
My initial impressions of the Nikon NIKKOR Z 50mm f/1.8 S are highly favorable, at least for handheld portraiture. Critical evaluation is coming.
Below, Western Mountaineering Flash XR down jacket is as good a jacket as you can buy at any price, with 850 fill power down.
