Here are first hands-on photos of the XF 8-16mm f/2.8 R LM WR and GF 250mm f/4 R LM OIS WR lenses.
As you might remember the company has updated the X-mount and G-mount lens roadmaps a few weeks ago. One of them is the XF 8-16mm f/2.8 WR lens that is schedule for mid-2018. The other X-series model is the XF 200mm f/2 R LM OIS WR lens. From the WR symbol we can also say that these products will be weathersealed.
