The development concept for XF50-140mmF2.8 R LM OIS WR was “to achieve the image quality and function of F2.8 zoom lens with the size of F4 zoom lens.”
In order to find the right balance of quality, functionality, durability with the size and weight in mind, Fujifilm designer and developer looked into every aspect of the lens and started from scratch.They cut the weight at 0.1gram level for each part of the lens and tested the lens over and over.
What you see hidden inside the lens is the trace of the effort put into create the flagship lens.
