Big Head Taco unboxed the Fujifilm X100F Brown and beyond the different wrap, everything else is the same in the box. During the unboxing, he did mention that the brown wrap felt more leather like so maybe Fujifilm used a higher quality material to wrap the camera with than they normally do, which will also likely be used on the Fujifilm X-E3 Brown.
Adorama currently has the Fujifilm X100F discounted and you can bundle it with the Fujifilm TCL-X100 II here as a special offer. This is a great deal and hopefully, B&H Photo will match it soon. The Fujifilm TCL-X100 II is a 1.4x upconverter that gives the Fujifilm X100F an effective focal length of 50mm if you’re not familiar with it and it is a very useful tool to accompany the X100F.
