If you are in the X system and want a high-performance telephoto lens, the XF 400mm f/4.5 is a great place to start.

I think that this lens is really nice design and a welcome addition to the X series lineup.

For wildlife and birding photographers needing a lightweight lens, strong and pleasing bokeh, and hardcore weather resistance, the XF 400mm F4.5 R LM OIS WR sounds like a solid choice.
-
The XF400mmF4.5 R LM OIS WR really surprised me. For a lens with this much reach, it’s remarkably light and easy to carry, even after a full day in the field.

I think the speed and the length that you get from this lens is really impressive. A 600 equivalent that shoots down to 4.5, so you can really throw out that background.

This lens changed the distance between me and those things, but it didn't change the photographers's vision itself.
