Overview
(From company literature) The GF1.4X TC WR is a 1.4x teleconverter for G Mount. Attaching the teleconverter to the Fujinon GF250mF4 R LM OIS WR allows for telephoto shooting at a focal length of 350mm (approximately 277mm in 35mm format equivalent) while maintaining superior image quality. The maximum aperture is reduced by one F stop. As both the lens and the teleconverter are high quality, there’s hardly any deterioration in MTF when the teleconverter is attached.
The FUJINON Teleconverter GF1.4X TC WR will be available in Late May 2018 for USD $849.95 and CAD $1,059.99.
