I mentioned that Foto Erhardt in Germany offers a free SmallRig grip with every Nikon Zf camera purchase. The grip can be purchased separately directly from SmallRig (they do offer international shipping) and is also available at WEX UK. The new grip should also be soon listed at Adorama, Amazon. and B&H Photo.
Some of the first Zf reviews I saw online mentioned that the camera is heavy and an actual grip could be very helpful.
