It seems that Amazon US currently has a new batch of GFX 100 medium format mirrorless camera shipping soon. You can now pre-order Fujifilm GFX 100 at Amazon US again. Unlike B&H Photo Video and Adorama, Amazon usually open pre-order when they actually receive new batch of items from manufacturers. So order soon before sold out again.
Venus Optics has announced the new Laowa 17mm f/4 GFX Zero-D lens for Fujifilm GFX medium format cameras. The US price for Laowa 17mm f/4 GFX lens is $1,199, now available for pre-order at B&H Photo Video/Adorama.
