The 50-140mm f/2.8 lens is perhaps one of the most impressive lenses in the entire Fuji X-Mount lineup. This red-badged XF zoom combines impressive construction quality with outstanding optics, but it’s not without its quirks. I rented this lens as part of the Fuji Professional Rental Service and got to spend a few weeks testing it out. Read on to hear my thoughts! Fuji has really done a great job on the construction of the 50-140mm f/2.8. It’s a solid and weighty lens (at nearly 4 lbs) and it looks great in person. It achieves it’s WR (Weather Resistant) designation thanks in part to the fact that all of the focusing mechanism is inside of the lens itself. I’ve had some issues with particles making their way into telescoping zooms in the past thanks to them sucking said particles in during zooming, and it’s nice to know that the 50-140mm f/2.8 is sealed in multiple places (including at the lens mount) to keep that type of risk down. The zoom ring is the most prominent element of the lens, and the manual focus ring sits just above it. Fuji has done a great job with the aperture ring which clicks nicely in 3rd stop intervals with a range from f/2.8 to f/22. The lens comes packaged with both lens caps, a lens hood with a built in opening for filter access and a tripod collar to mount the lens itself to a monopod or tripod……….
