Qustion regarding the Fujinon XT17sx45BRMK1 17x 4.5mm HD ENG Lens

Does anyone know if this lens could be compatible with an X-T4? It uses a 1/3" bayonet lens mount. I've been searching for an adapter bit without success.

Image circle of 1/3" lens it's really too small to be conveniently adapted to an APS-C sensor.

Better to look for a 2/3" lens with built-in doubler., with the XT4 you can use the sport finder mode or the high speed burst mode for still (1.29x crop)  and the fixed movie mode (1.29x crop) for video.

In this way, a 2/3" lens with the extender engaged and one of the above mentioned mode, will cover the entire sensor with no vignetting.

Another option is to add a 1.4x tele converter which eliminates the need for the crop modes.

A third solution for lens without built-in extender is to stack a 2x plus 1.4x converter.

There are few options about. how to adapt a 2/3" tlens o a Fuji X mount, depending  on the choise adopted among the use or not of external lens converter.

 

If still interested, I can send you links to the various mount adapters available.
