Fuji has previously said it had expected to launch a 23mm f/1.4 lens earlier this year.
The Fujinon XF 23mm f/1.4 R is designed to produce the 35mm viewing angle equivalent of a 35mm lens.
The seven-blade-diaphragm optic boasts a minimum focusing distance of around 28cm and is ideal for close-up shots, according to Fuji.
The 300g lens is due to go on sale in October priced £849.99.
In the spring, Fuji stressed the importance of making its customers aware that the company plans to have a range of Fujinon lenses as part of its X-mount compact camera system.
