The Fuji 1.4x teleconverter – a Hands-on review | Tom Grill
The Fujifilm XF 1.4x TC WR teleconverter is intended to fit two lens — the current 50-140mm f/2.8 zoom, and the 100-400mm to be released later this year — multiplying their focal length ranges by 1.4x with a loss of only one f/stop. This makes the 50-140mm a 70-196mm f/4, and the variable aperture 100-400mm f/4.5-5.6 lens a 140-560mm f/6.3-8 zoom, and means that the Fuji X mirrorless system now extends its optical system into the long telephoto range, albeit only with zooms. Anytime you put a teleconverter on a lens, you are going to compromise the quality of the original optics. The real question is: How much lens quality are you going to sacrifice? The very best teleconverters are usually made by the lens manufacturer and are dedicated to a particular lens set in a way that minimizes the loss in quality. Many off brand converters, on the other hand, can be downright awful. Because Fujifilm is known for its superb optics I went into this test thinking (and hoping) that the combination of the Fuji 50-140mm zoom plus 1.4x telextender would be capable of excellent results…..
